Introduction

The Internal Revenue Bulletin is the authoritative instrument

of the Commissioner of Internal Revenue for announcing official rulings and procedures of the Internal Revenue Service

and for publishing Treasury Decisions, Executive Orders, Tax

Conventions, legislation, court decisions, and other items of

general interest. It is published weekly.

It is the policy of the Service to publish in the Bulletin all substantive rulings necessary to promote a uniform application

of the tax laws, including all rulings that supersede, revoke,

modify, or amend any of those previously published in the

Bulletin. All published rulings apply retroactively unless otherwise indicated. Procedures relating solely to matters of internal management are not published; however, statements of

internal practices and procedures that affect the rights and

duties of taxpayers are published.

Revenue rulings represent the conclusions of the Service

on the application of the law to the pivotal facts stated in

the revenue ruling. In those based on positions taken in rulings to taxpayers or technical advice to Service field offices,

identifying details and information of a confidential nature are

deleted to prevent unwarranted invasions of privacy and to

comply with statutory requirements.

Rulings and procedures reported in the Bulletin do not have the

force and effect of Treasury Department Regulations, but they

may be used as precedents. Unpublished rulings will not be

relied on, used, or cited as precedents by Service personnel in

the disposition of other cases. In applying published rulings and

procedures, the effect of subsequent legislation, regulations,

court decisions, rulings, and procedures must be considered,

and Service personnel and others concerned are cautioned

against reaching the same conclusions in other cases unless

the facts and circumstances are substantially the same.

The Bulletin is divided into four parts as follows:

Part I.—1986 Code.

This part includes rulings and decisions based on provisions

of the Internal Revenue Code of 1986.

Part II.—Treaties and Tax Legislation.

This part is divided into two subparts as follows: Subpart A,

Tax Conventions and Other Related Items, and Subpart B,

Legislation and Related Committee Reports.

Part III.—Administrative, Procedural, and Miscellaneous.

To the extent practicable, pertinent cross references to these

subjects are contained in the other Parts and Subparts. Also

included in this part are Bank Secrecy Act Administrative

Rulings. Bank Secrecy Act Administrative Rulings are issued

by the Department of the Treasury’s Office of the Assistant

Secretary (Enforcement).

Part IV.—Items of General Interest.

This part includes notices of proposed rulemakings, disbarment and suspension lists, and announcements.

The last Bulletin for each month includes a cumulative index

for the matters published during the preceding months. These

monthly indexes are cumulated on a semiannual basis, and are

published in the last Bulletin of each semiannual period.

The contents of this publication are not copyrighted and may be reprinted freely. A citation of the Internal Revenue Bulletin as the source would be appropriate.

SUPPLEMENTARY INFORMATION:

Authority

This Treasury Decision contains final

regulations that amend the Income Tax

Regulations (26 CFR part 1) under section 415, related to the definition of the

term “compensation” for purposes of

May 26, 2026

contribution and benefit limits applicable

to qualified retirement plans. These final

regulations are issued under the authority

granted by section 415(j) of the Internal

Revenue Code (Code), which authorizes

the Secretary of the Treasury or his delegate (Secretary) to prescribe such regulations as may be necessary to carry out the

purposes of section 415. These final regulations are also issued under the authority

granted by section 7805(a), which authorizes the Secretary to prescribe all needful

rules and regulations for the enforcement

of the Code.

Background

This document contains amendments

to regulations under section 415 of the

Code, which generally imposes limitations on the annual amount that a qualified

retirement plan may provide, with respect

to a participant, in either benefit payments

or in contributions and other additions to

the plan. These limitations generally are

based on a participant’s compensation.

Section 415(c)(3) provides that the term

“participant’s compensation” means the

compensation of the participant from the

employer for the year.

Section 1.415(c)-2(a) of the Income

Tax Regulations generally provides that

compensation from the employer within

the meaning of section 415(c)(3) includes

all items of remuneration described in

§1.415(c)-2(b) to the extent that the

amounts are includible in gross income,

but excludes the items of remuneration

described in §1.415(c)-2(c), such as contributions made by an employer to a plan

of deferred compensation to the extent

that the contributions are not includible in

the gross income of the employee for the

taxable year in which contributed.

Section 7873(a)(1) provides that no

tax shall be imposed on income derived

from a fishing rights-related activity of

an Indian tribe by (A) a member of the

Indian tribe directly or through a qualified Indian entity, or (B) a qualified Indian

entity. Section 7873(a)(2) provides that

no employment tax shall be imposed on

remuneration paid for services performed

in a fishing rights-related activity of an

Indian tribe by a member of such tribe

1512

for another member of such tribe or for a

qualified Indian entity.

On November 15, 2013, proposed

regulations under section 415 were published in the Federal Register (78 FR

68780). The proposed regulations would

provide that income described in section

7873(a) (“fishing rights-related income”)

is included in the definition of compensation under section 415. Specifically, the

proposed regulations would provide that

amounts paid to a member of an Indian

tribe as remuneration for services performed in a fishing rights-related activity

(as defined in section 7873(b)(1)) do not

fail to be treated as compensation under

§1.415(c)-2(b)(1) and (b)(2) (and are not

excluded from the definition of compensation pursuant to §1.415(c)-2(c)(4)) merely

because those amounts are not subject to

income tax or employment taxes as a result

of section 7873(a)(1) and (a)(2). Thus, the

determination of whether an amount constitutes wages, salaries, or earned income

for purposes of §1.415(c)-2(b)(1) or (b)(2)

is made without regard to the exemption

from income tax under section 7873(a)(1)

or employment tax under section 7873(a)

(2). In addition, by permitting fishing

rights-related income to be treated as

wages, salaries, or earned income under

§1.415(c)-2(b)(1) and (b)(2), plans that

accept contributions of fishing rights-

related income would not be precluded

from utilizing the safe harbor definitions

of compensation under §1.415(c)-2(d)(2)

and (d)(3).

Written comments on the proposed

regulations were received and considered.

The Department of the Treasury (Treasury Department) and the IRS did not

receive any requests for a public hearing

to address the proposed regulations, and,

accordingly, no hearing was held. The

Treasury Department held a Tribal consultation on this proposed rule on December 17, 2013. Additionally, on August 22,

2024, the Treasury Department met with

the Treasury Tribal Advisory Committee,

Subcommittee on Parity and Reform and

received additional feedback on the proposed regulations. After consideration of

the comments received, the proposed regulations are adopted by this Treasury decision without material modification.

Bulletin No. 2026–22

Summary of Comments and

Explanation of Provisions

A. Treatment of Fishing Rights-Related

Income as Compensation under Section

415

The proposed regulations were issued

primarily in response to requests from

the Tribal community that the Treasury

Department and the IRS address whether

contributions can be made to qualified retirement plans based on fishing

rights-related income. Under the proposed

regulations, fishing rights-related income

would not fail to be treated as compensation under §1.415(c)-2(b)(1) and (b)(2)

(and is not excluded from the definition of

compensation pursuant to §1.415(c)-2(c)

(4)) merely because those amounts are not

subject to income tax or employment tax

as a result of section 7873(a)(1) or (a)(2).

Commenters generally reacted favorably to this proposed rule, stating that

the proposed regulations provided much

needed clarity on how plans should treat

fishing rights-related income paid to

employees subject to section 7873 (Tribal

employees) under section 415. The Treasury Department and the IRS also received

comments stating that additional guidance is needed with respect to a variety

of issues relating to fishing rights-related

income in retirement plans. Many of these

issues are outside the scope of these regulations, which are modifying the definition

of compensation for purposes of section

415, and so the text of the final regulations

does not address them. However, this preamble (under the headings “Taxation of

Distributions,” “Treating Contributions as

Roth Contributions,” and “Self-Employed

Tribal Members” in this Summary of

Comments and Explanation of Provisions)

provides clarifying information relating to

many of these issues.

B. Taxation of Distributions

The preamble to the proposed regulations requested comments regarding the

taxation of qualified plan distributions

attributable to contributions based on fishing rights-related income, and the application of section 72(f)(2)1 to such distributions. All of the comments received

requested that distributions attributable

to contributions based on fishing rights-

related income should not be taxable to a

Tribal employee.

Several of the commenters referred

to Hall v. Commissioner, 76 T.C.M. 473

(1998), in which the petitioner was a

full-time employee in a Tribal fish hatchery who received a choice between an

employer contribution to a retirement

account or an employer contribution to a

health plan. In 1992, the petitioner elected

the retirement benefit and the employer

contributed a monthly amount to an individual retirement account (IRA). That

same year, the petitioner received early

distributions from the IRA attributable

to those employer contributions and to

income earned in the IRA. The Tax Court

generally found that, under section 72 (as

modified by section 408(d)(1) and (2)), the

amount of the distributions attributable to

contributions based on fishing rights-

related income represents a nontaxable

return of his investment in the contract,

but added that the amount of distributions

attributable to the earnings on the IRA

contributions represents accrued income

that is taxable to the petitioner.

In response to the requests to clarify

the taxation of qualified plan distributions

attributable to contributions based on fishing rights-related income, the Treasury

Department and the IRS have determined

that the holding in Hall v. Commissioner

should apply to these distributions. Thus,

consistent with Hall, any contribution to

a qualified retirement plan that is attributable to remuneration for services performed by a Tribal employee in a fishing

rights-related activity is treated as investment in the contract for a plan participant

under the rules of section 72(f)(2). Therefore, any distribution of such amounts is

nontaxable to the participant. However,

also consistent with Hall, the amount of

the distribution attributable to earnings on

those contributions is taxable.

Another commenter raised an issue

regarding the ordering for determining

the taxable and nontaxable amounts of

a qualified retirement plan distribution.

Referring to qualified retirement plan

distributions attributable to fishing rights-

related income, this commenter suggested

that plan participants be allowed to elect

the order in which the qualified retirement

plan distributions are made so that the nontaxable amounts could be received first.

This suggestion is not adopted because

it is inconsistent with the basis recovery

rules in section 72.2 Tribal employees will

have investment in the contract on contributions to the plan attributable to fishing

rights-related income, and thus the general basis recovery rules of section 72 will

apply.

The Treasury Department and the

IRS also received comments concerning

the treatment of earnings on contributions attributable to fishing rights-related

income and the treatment of employer

matching and profit-sharing contributions

related to contributions attributable to fishing rights-related income. As explained in

the preceding paragraph, section 72 provides basis recovery rules for determining the taxable and nontaxable portions

of a distribution. Section 72(f) applies to

amounts contributed by the employer and

does not distinguish employer matching

or employer profit-sharing contributions

from employee elective deferrals (which

are treated as employer contributions pursuant to section 402(e)(3)). Therefore, section 72(f)(2) applies not only to employee

elective deferrals but also to employer

matching and employer profit-sharing

contributions attributable to remuneration for services performed by a Tribal

employee in a fishing rights-related activity. As explained in Hall v. Commissioner,

however, section 72(f)(2) does not apply

to earnings. Therefore, qualified retirement plan distributions attributable to the

earnings on contributions based on fishing rights-related income generally will

Section 72(f)(2) treats employer contributions as investment in the contract if those amounts would not have been includible in income of the employee had they been paid directly to the

employee.

Section 72(b) provides that gross income does not include that part of any amount received as an annuity which bears the same ratio to such amount as the investment in the contract bears

to the expected return under the contract.

Bulletin No. 2026–22

1513

May 26, 2026

be taxable to the participant and the basis

recovery rules of section 72 will apply in

determining the portion of a distribution

that is includible in income.

C. Treating Contributions as Roth

Contributions

One commenter suggested that guidance be provided to allow a qualified

retirement plan to treat contributions

attributable to fishing rights-related

income as either Roth contributions or

after-tax contributions. The commenter

added that the guidance could provide

that, if the plan permits participants

to make Roth contributions, then the

employee’s contributions attributable to

fishing rights-related income would be

treated as Roth contributions. If the plan

does not provide for Roth contributions,

then these contributions would be treated

as after-tax contributions.

Section

1.401(k)-1(f)(2)

provides

that if an elective contribution would not

have been includible in gross income if

the amount had been paid directly to the

employee (rather than being subject to a

cash or deferred election), the elective contribution is nevertheless permitted to be a

designated Roth contribution, provided the

employee is entitled to treat the amount as

an investment in the contract pursuant to

section 72(f)(2). As previously stated in this

preamble under the heading “Taxation of

Distributions,” any contributions attributable to remuneration for services performed

in a fishing rights-related activity are treated

as investment in the contract for the plan

participant under the rules of section 72(f)

(2). Therefore, contributions attributable to

fishing rights-related income are permitted

to be designated Roth contributions under a

qualified retirement plan that permits participants to make those contributions.

D. Self-Employed Tribal Members

Two commenters asked about the retirement plan options for Tribal members who

earn fishing rights-related income but who

may not be employed by an Indian tribe.

Section 401(a) provides that a plan of an

employer is a qualified plan only if it is created or organized for the exclusive benefit

of the employer’s employees or their beneficiaries. For these purposes, whether an

May 26, 2026

individual is an employee of the employer

maintaining a plan is generally determined

under common law principles. See Nationwide Mutual Insurance Co. v. Darden, 503

U.S. 318 (1992). Self-employed individuals generally may not participate in a qualified retirement plan sponsored by another

employer. Moreover, whether an individual

earns fishing-rights related income is not

determinative of whether that individual is

an employee. However, an individual who

is self-employed under section 401(c)(1)

may nevertheless maintain his or her own

qualified retirement plan, such as a section

401(k) plan.

E. Additional Comments

Commenters also requested guidance

on several other issues, including guidance

permitting rollover of contributions attributable to fishing rights-related income from

a nonqualified plan to a qualified plan, guidance permitting Tribal employers to take

retroactive action to permit Tribal employees to contribute fishing rights-related

income to a qualified plan, and guidance

on testing for contributions attributable to

fishing rights-related income. These comments are all beyond the scope of these regulations and, in certain cases, the requested

guidance may not be permissible under the

Code (for example, rollover of amounts

from a nonqualified plan into a qualified

plan). However, the Treasury Department

and IRS will continue to review comments

that are beyond the scope of these regulations and consider if any further guidance

is needed. If additional guidance is needed,

the Treasury Department and the IRS will

conduct Tribal consultation pursuant to

Executive Order 13175.

Applicability Date

These final regulations apply for plan

years ending on or after May 4, 2026.

Special Analyses

I. Regulatory Planning and Review

OMB’s Office of Information and Regulatory Affairs has determined that this

regulation is not significant and is not subject to review under section 6(b) of Executive Order 12866, as amended.

1514

II. Regulatory Flexibility Act

It is hereby certified that these final

regulations will not have a significant

economic impact on a substantial number of small entities within the meaning of section 601(6) of the Regulatory

Flexibility Act (5 U.S.C. chapter 6). This

certification is based on the fact that only

5,000 to 6,000 employees nationwide are

estimated to earn fishing rights-related

income. Therefore, a regulatory flexibility

analysis under the Regulatory Flexibility

Act is not required.

Pursuant to section 7805(f) of the Code,

the proposed regulations that preceded

these final regulations were submitted to

the Chief Counsel for the Office of Advocacy of the Small Business Administration

for comment on their impact on small business, and no comments were received.

Consultation and Coordination With

Tribal Governments

In addition to written comments

responding to the proposed regulations,

these final regulations reflect comments

provided in a Tribal consultation held on

December 17, 2013, as well as comments

provided in a meeting with members of

the Treasury Tribal Advisory Committee

Subcommittee on Parity and Reform on

August 22, 2024.

Drafting Information

The principal author of these regulations is Jamie Dvoretzky, Office of Associate Chief Counsel (Employee Benefits,

Exempt Organizations, and Employment

Taxes). However, other personnel from

the Treasury Department and the IRS participated in the development of these regulations.

eral short-term rate for any month is the

federal short-term rate determined during

that month by the Secretary in accordance

with section 1274(d), rounded to the nearest full percent (or, if a multiple of 1/2 of

1 percent, the rate is increased to the next

highest full percent).

Notice 88-59, 1988-1 C.B. 546,

announced that in determining the quarterly interest rates to be used for overpayments and underpayments of tax under

section 6621, the Internal Revenue Service will use the federal short-term rate

based on daily compounding because that

rate is most consistent with section 6621

which, pursuant to section 6622, is subject

to daily compounding.

The federal short-term rate determined

in accordance with section 1274(d) during

April 2026 is the rate published in Revenue Ruling 2026-9, 2026-19 IRB 897, to

take effect beginning May 1, 2026. The

federal short-term rate, rounded to the

nearest full percent, based on daily compounding determined during the month

of April 2026 is 4 percent. Accordingly,

an overpayment rate of 7 percent (6 percent in the case of a corporation) and an

underpayment rate of 7 percent are established for the calendar quarter beginning

July 1, 2026. The overpayment rate for

the portion of a corporate overpayment

exceeding $10,000 for the calendar quarter beginning July 1, 2026, is 4.5 percent.

The underpayment rate for large corporate

underpayments for the calendar quarter

beginning July 1, 2026, is 9 percent. These

rates apply to amounts bearing interest

during that calendar quarter.

Sections 6654(a)(1) and 6655(a)(1) provide that the underpayment rate established

under section 6621 applies in determining

the addition to tax under sections 6654 and

6655 for failure to pay estimated tax for

any taxable year. Thus, the 7 percent rate

also applies to estimated tax underpayments for the third calendar quarter beginning July 1, 2026. In addition, pursuant to

section 6603(d)(4), the rate of interest on

section 6603 deposits is 4 percent for the

third calendar quarter in 2026.

Interest factors for daily compound

interest for annual rates of 4.5 percent, 6

percent, 7 percent and 9 percent are published in Tables 14, 17, 19 and 23 of Rev.

Proc. 95-17, 1995-1 C.B. 566, 569, 571,

L. 116-260, 134 Stat. 3051 (December

27, 2020), § 13104 of Pub. L. 117-169,

136 Stat. 1818 (August 16, 2022), commonly known as the Inflation Reduction

Act (IRA), and § 70522 of Pub. L. 11921, 139 Stat. 72 (July 4, 2025), commonly

known as the One, Big, Beautiful Bill Act

(OBBBA).

Section 45Q(a)(1) allows a credit of

$20 per metric ton of qualified carbon

oxide (i) captured by the taxpayer using

carbon capture equipment which is originally placed in service at a qualified facility before the date of the enactment of the

BBA, (ii) disposed of by the taxpayer in

secure geological storage, and (iii) not

used by the taxpayer as a tertiary injectant

in a qualified enhanced oil or natural gas

recovery project.

Section 45Q(a)(2) allows a credit of

$10 per metric ton of qualified carbon

oxide (i) captured by the taxpayer using

carbon capture equipment which is originally placed in service at a qualified

facility before the date of the enactment

of the BBA, and (ii) either (I) used by the

taxpayer as a tertiary injectant in a qualified enhanced oil or natural gas recovery

project and disposed of by the taxpayer in

secure geological storage or (II) utilized

by the taxpayer in a manner described in

§ 45Q(f)(5).

Section 45Q(b)(3) provides that, for

purposes of determining the carbon oxide

sequestration credit under this section,

a taxpayer may elect to have the dollar

amounts applicable under § 45Q(a)(1)

or (2) apply in lieu of the dollar amounts

applicable under § 45Q(a)(3) or (4) for

each metric ton of qualified carbon oxide

which is captured by the taxpayer using

carbon capture equipment which is originally placed in service at a qualified facility on or after the date of the enactment of

the BBA.

Notice 2022-38 provided that 2022

was the final calendar year for which a

taxpayer may claim a § 45Q credit under

§ 45Q(a)(1) and (2) for qualified carbon

oxide that is captured by carbon capture

equipment originally placed in service at a

qualified facility before the date of enactment of the BBA. Therefore, the inflation

adjustment amounts in section 3 of this

notice only apply if a taxpayer elects under

§ 45Q(b)(3) to apply the dollar amounts

applicable under § 45Q(a)(1) or (2) in lieu

of the dollar amounts applicable under §

45Q(a)(3) or (4).

Under § 45Q(f)(7), for taxable years

beginning in a calendar year after 2009,

the dollar amounts contained in § 45Q(a)

(1) and (2) must be adjusted for inflation

by multiplying such dollar amount by the

inflation adjustment factor for such calendar year determined under § 43(b)(3)(B),

determined by substituting “2008” for

“1990.”

Section 43(b)(3)(B) defines the term

“inflation adjustment factor” as, with

respect to any calendar year, a fraction the

numerator of which is the GNP implicit

price deflator for the preceding calendar

year and the denominator of which is the

GNP implicit price deflator for 1990. For

purposes of § 45Q(f)(7), for the 2025 calendar year, the inflation adjustment factor

is a fraction the numerator of which is

the GNP implicit price deflator for 2025

(128.888) and the denominator of which

is the GNP implicit price deflator for 2008

(88.046).

SECTION 3. INFLATION

ADJUSTMENT FACTOR

The inflation adjustment factor for

calendar year 2026 is 1.4639. The § 45Q

credit for calendar year 2026 is $29.28 per

metric ton of qualified carbon oxide under

§ 45Q(a)(1) and $14.64 per metric ton of

qualified carbon oxide under § 45Q(a)(2).

2025 Section 45K(d)(2)(C)

Reference Price

Notice 2026-30

SECTION 1. PURPOSE

This notice publishes the reference

price under § 45K(d)(2)(C) of the Internal Revenue Code for calendar year

2025.1 The credit period for the nonconventional source production credit under

§ 45K ended on December 31, 2013, for

facilities producing coke or coke gas

(other than from petroleum-based products). However, the reference price continues to apply in determining the amount

of the enhanced oil recovery credit under

§ 43, the marginal well production credit

for qualified crude oil production under

§ 45I, and the applicable percentage

under § 613A to be used in determining

percentage depletion in the case of oil

and natural gas produced from marginal

properties.

SECTION 2. BACKGROUND

Section 45K(d)(2)(C) provides that the

term “reference price” means, with respect

to a calendar year, the Secretary’s estimate

of the annual average wellhead price per

barrel for all domestic crude oil the price

of which is not subject to regulation by the

United States.

Section 43(a) provides that, for purposes of § 38, the enhanced oil recovery

credit for any taxable year is an amount

equal to 15 percent of the taxpayer’s qualified enhanced oil recovery costs for such

taxable year.

Section 43(b)(1) provides that the

amount of enhanced oil recovery credit

for any taxable year shall be reduced by

an amount which bears the same ratio to

the amount of such credit (determined

without regard to this paragraph) as (A) the amount by which the reference

price for the calendar year preceding the

calendar year in which the taxable year

begins exceeds $28, bears to (B) $6.

Section 43(b)(2) provides that the term

“reference price” means, with respect

to any calendar year, the reference price

determined for such calendar year under

§ 45K(d)(2)(C).

Section 45I(a) provides that, for purposes of § 38, the marginal well production credit for any taxable year is an

amount equal to the product of the credit

amount and the qualified crude oil production and the qualified natural gas production which is attributable to the taxpayer.

Section 45I(b)(1) provides that for

crude oil production, the amount of the

marginal well production credit is $3 per

barrel of qualified crude oil production.

Section 45I(b)(2) provides that the

$3 amount under § 45I(b)(1) shall be

reduced (but not below zero) by an

amount which bears the same ratio to

such amount (determined without regard

to this paragraph) as – (i) the excess (if

any) of the applicable reference price

over $15, bears to (ii) $3. The applicable reference price for a taxable year is

the reference price of the calendar year

preceding the calendar year in which the

taxable year begins.

Section 45I(b)(2)(C) provides that for

qualified crude oil production the term

“reference price” means, with respect

to any calendar year, the reference price

determined under § 45K(d)(2)(C).

Section 613A(c)(6)(A) provides, in

general, that the allowance for depletion

under § 611 shall be computed in accordance with § 613 with respect to - (i) so

much of the taxpayer’s average daily marginal production of domestic crude oil as

does not exceed the taxpayer’s depletable

oil quantity (determined without regard

to paragraph (3)(A)(ii)), and (ii) so much

of the taxpayer’s average daily marginal

production of domestic natural gas as

does not exceed the taxpayer’s depletable

natural gas quantity (determined without

regard to paragraph (3)(A)(ii)), and the

applicable percentage shall be deemed to

be specified in subsection (b) of § 613 for

purposes of subsection (a) of that section.

Section 613A(c)(6)(C) provides that

the term “applicable percentage” means

the percentage (not greater than 25 per-

cent) equal to the sum of - (i) 15 percent,

plus (ii) 1 percentage point for each whole

dollar by which $20 exceeds the reference price for crude oil for the calendar

year preceding the calendar year in which

the taxable year begins. For purposes of

this paragraph, the term “reference price”

means, with respect to any calendar year,

the reference price determined for such

calendar year under § 45K(d)(2)(C).

Rev. Proc. 2026-21

SECTION 1. PURPOSE

This revenue procedure describes a

program for letter rulings with respect to

certain issues solely under the jurisdiction

of the Associate Chief Counsel (Corporate). This program does not diminish the

availability of letter rulings under existing

programs.

SECTION 2. CHANGES

This revenue procedure modifies and

amplifies Rev. Proc. 2026-1, 2026-1

I.R.B. 1, which explains how the Internal Revenue Service (Service) provides

advice to taxpayers on issues under the

jurisdiction of the Associate Chief Counsel (Corporate). This revenue procedure

also modifies and amplifies Rev. Proc.

2026-3, 2026-1 I.R.B. 143, which sets

Unless otherwise specified, all “section” references will be to the Internal Revenue Code, as amended, or the Income Tax Regulations.

May 26, 2026

1538

Bulletin No. 2026–22

forth the areas of the Internal Revenue

Code (Code)1 under the jurisdiction of

the Associate Chief Counsel (Corporate)

relating to issues on which the Service

will not issue letter rulings.

SECTION 3. BACKGROUND

.01 Prior Ruling Policy. As described

in this section 3.01, the Service has taken

various positions over time on issuing letter rulings on only part of an integrated

transaction.

(1) Rev. Proc. 2001-3. Rev. Proc. 20013, 2001-1 I.R.B. 111, modified by Ann.

2001-25, 2001-11 I.R.B. 895, provided

that the Service would not rule on whether

a transaction qualifies under § 332, 351,

368(a)(1)(A), (B), (C), (E) or (F), or 1036,

and whether various consequences (such

as nonrecognition and basis) result from

the application of that section, unless the

Service determined that there was a significant issue that must be resolved in order

to decide those matters. In that case, the

Service would rule on the entire transaction and not just on the significant issue.

See section 3.01(29) of Rev. Proc. 2001-3.

(2) Rev. Proc. 2009-25. Rev. Proc.

2009-25, 2009-24 I.R.B. 1088, announced

a pilot program for letter rulings on issues

arising in the context of distributions to

which § 355 applies (§ 355 distributions).

Under this program, a taxpayer could

request a letter ruling on part of a larger

transaction or on a particular issue under a

Code section that a transaction presented.

In turn, the Service would issue a letter

ruling on the particular issue raised in the

letter ruling request and not on any other

issue (including, in some cases, qualification of the distribution under § 355) or on

any other aspect of the transaction.

(3) Rev. Proc. 2013-32. Rev. Proc.

2013-32, 2013-28 I.R.B. 55, provided that

the Service no longer would rule on (i)

whether a transaction qualifies for nonrecognition treatment under § 332, 351, 355,

or 1036, (ii) whether a transaction constitutes a reorganization within the meaning

of § 368, or (iii) the various tax consequences resulting from the application of

those Code sections. Instead, the Service

would rule only on significant issues presented in transactions described in those

Code sections (significant issue rulings).

Rev. Proc. 2013-32 further provided that

(i) the Service would not issue a letter ruling with respect to an issue that is clearly

and adequately addressed by statute, regulations, decision of a court, or authority

published in the Internal Revenue Bulletin

(comfort ruling), but that (ii) except with

respect to issues under §§ 332, 351, 355,

368, and 1036 and the tax consequences

resulting from the application of those

Code sections, an Associate office may,

in its discretion, issue a comfort ruling if

the Associate office is otherwise ruling on

another issue arising in the same transaction. Rev. Proc. 2013-32 also provided

that the pilot program announced in Rev.

Proc. 2009-25 was discontinued.

(4) Rev. Proc. 2017-52. Rev. Proc.

2017-52, 2017-41 I.R.B. 283, provides

procedures for requesting letter rulings

regarding § 355 distributions. Rev. Proc.

2017‑52 established a pilot program to

issue letter rulings that address the general Federal income tax consequences of

a § 355 distribution. Rev. Proc. 2017-52

also provides procedures for requesting

such rulings and clarifies procedures for

requesting rulings on significant issues

presented in those transactions. Rev. Proc.

2017-52 modified and superseded a number of prior revenue procedures, including

superseding Rev. Proc. 2009-25 and Rev.

Proc. 2013-32.

(5) Rev. Proc. 2024-1 and Rev. Proc.

2024-3. Rev. Proc. 2024-1, 2024-1

I.R.B. 1, and Rev. Proc. 2024-3, 2024-1

I.R.B. 143, removed issues under §§ 332,

351, 368, and 1036 from the list of areas in

which letter rulings ordinarily would not

be issued, permitted the issuance of comfort rulings relating to transactions under

§§ 332, 351, 355, 368, 1036, and related

operative provisions, and ended the practice of issuing significant issue rulings,

including with respect to § 355 distributions. See sections 6.11 and 16 of Rev.

Proc. 2024-1; section 1.02 of Rev. Proc.

2024-3.

.02 Current Ruling Policy. The Service

ordinarily will not issue a letter ruling

on only part of an integrated transaction.

However, if part of an integrated transaction falls under an area of the Code,

including those under the jurisdiction of

the Associate Chief Counsel (Corporate),

on which the Service will not issue letter rulings, the Service may issue a letter

ruling on other parts of the transaction.

Section 6.03 of Rev. Proc. 2026-1; section 4.02(2) of Rev. Proc. 2026-3. If it is

impossible for the Service to determine the

tax consequences of an integrated transaction without resolving an issue on which

the Service will not issue rulings (no-rule

issue) involving a part of the transaction

or a related transaction, the taxpayer must

state in its letter ruling request to the best

of its knowledge and belief the tax consequences of the no-rule issue. The Service’s

letter ruling will state that the Service did

not consider, and no opinion is expressed

upon, that issue. In appropriate cases,

notwithstanding the taxpayer’s representation, the Service may decline to issue a

letter ruling on the integrated transaction

due to the relevance of the no-rule issue.

Section 2.03 of Rev. Proc. 2026-3.

In addition, except with respect to

issues under §§ 332, 351, 355, 368, 1036,

and related operative provisions, the Service ordinarily will not issue comfort rulings, but the Service may in its discretion

decide to issue a comfort ruling if the

Service is otherwise issuing a letter ruling

to the taxpayer on another issue arising

in the same transaction. Section 6.11 of

Rev. Proc. 2026-1; section 4.02(9) of Rev.

Proc. 2026-3.

Furthermore, the Service will not issue

letter rulings on questions that the Service

determines, in its discretion, should not

be answered in the interest of sound tax

administration, including due to resource

constraints. Section 3.02(10) of Rev. Proc.

2026-3.

A taxpayer requesting a letter ruling

solely or primarily under the jurisdiction

of the Associate Chief Counsel (Corporate) may request fast-track processing,

but not expedited handling, of that letter

ruling request. However, expedited handling, but not fast-track processing, may

be available for letter ruling requests that

Unless otherwise provided, all "section" or "§" references are to sections of the Code or the Income Tax Regulations (26 CFR part 1).

Bulletin No. 2026–22

1539

May 26, 2026

include a closing agreement with respect

to an issue or letter ruling requests for an

extension of time for making an election

or other relief. Section 7.02(4) of Rev.

Proc. 2026-1; Rev. Proc. 2023-26, 202333 I.R.B. 486.

.03 Feedback Requesting Significant

Issue Rulings. The Service has received

numerous informal comments from taxpayers and practitioners regarding the

time required to process letter ruling

requests and the scope of those letter ruling requests. Taxpayers and practitioners

have recommended that the Service reinstate the practice of issuing significant

issue rulings. To use Service resources

more efficiently, and to increase the availability and timeliness of letter rulings, this

revenue procedure establishes a significant issue ruling program to allow taxpayers to request rulings on one or more

issues that—

(1) Are solely under the jurisdiction of

the Associate Chief Counsel (Corporate);

(2) Are significant (as defined in section 4.02 of this revenue procedure); and

(3) Involve the tax consequences or

characterization of a transaction (or part

of a transaction) that is described in § 332,

351, 355, 368, or 1036.

SECTION 4. SCOPE

.01 Significant Issue Ruling Program. Under the significant issue ruling

program described in this revenue procedure, taxpayers may request, and the

Service may issue, a ruling on part of

an integrated transaction described in

§ 332, 351, 355, 368, or 1036. In addition, taxpayers may request, and the Service may issue, a ruling on a particular

legal issue under a section of the Code

or the Income Tax Regulations with

respect to a transaction (or part thereof)

rather than a ruling that addresses all

aspects of that section (or any other

section) with respect to the transaction

(or part thereof). For example, the Service may issue a letter ruling addressing significant issues presented by the

application of § 355(e), 1.368-1(d), or

1.368-2(k), even though the ruling does

not address overall qualification of the

transaction under § 355 or 368.

In addition, the Service may rule on

the tax consequences (such as nonrec-

May 26, 2026

ognition and basis) resulting from integrated transactions described in § 332,

351, 355, 368, or 1036 to the extent that

a significant issue is presented under

related Code sections that address such

tax consequences. For example, a § 351

exchange that does not present any significant issues under § 351 may present

a significant issue regarding the application of § 358 to the transferor in the

exchange.

This revenue procedure does not limit

the number of significant issues with

respect to a transaction that may be the

subject of a single letter ruling. However,

the Service reserves the right to rule on

any other issue related to the transaction

(including ruling adversely) if the Service

believes that doing so would be in the

interest of sound tax administration.

If the Service issues a letter ruling on a

significant issue under Rev. Proc. 2026‑1

as modified and amplified by this revenue

procedure, the letter ruling will state that

no opinion is expressed as to the overall tax consequences of the transactions

described in the letter ruling or as to any

issue or step not specifically addressed by

the letter ruling.

.02 Significant Issue. A significant

issue is a germane and specific issue of

law, provided that a ruling on the issue

would not be a comfort ruling or the conclusion in such a ruling otherwise would

not be essentially free from doubt. An

issue is germane if resolution of the issue

is necessary to determine an element

of the tax treatment of the transaction.

An issue is specific if it is the narrowest articulation of the germane issue. A

change of circumstances arising after a

transaction ordinarily does not present

a significant issue with respect to the

transaction.

SECTION 5. PROCEDURE

.01 In General. Letter ruling requests

submitted under Rev. Proc. 2026‑1 as

modified and amplified by this revenue

procedure must comply with the requirements set forth in Rev. Proc. 2026-1,

including the requirements of section

6.03 of Rev. Proc. 2026-1, as modified

and amplified by this revenue procedure.

All pertinent no-rule policies described in

Rev. Proc. 2026-3, as modified and ampli-

1540

fied by this revenue procedure, will govern

requests for letter rulings made pursuant

to this revenue procedure. For example,

see section 3.01(66) of Rev. Proc. 2026-3

(no-rule policy regarding business purpose under § 355).

In preparing a letter ruling request

under Rev. Proc. 2026‑1 as modified

and amplified by this revenue procedure,

taxpayers should continue to consult

other applicable revenue procedures. For

example, see Rev. Proc. 2025-30, 202542 I.R.B. 489 and Rev. Proc. 2017-52.

However, the letter ruling request must

include the information and representations described in such revenue procedures (as applicable) only to the extent

that they relate to the significant issue.

Further, when a taxpayer is requesting a

ruling regarding a significant issue under

a section of the Code or the Income Tax

Regulations (for example, § 355(e)), the

taxpayer must provide a representation

(to the best knowledge and belief of the

taxpayer) that the transaction would otherwise satisfy the requirements under

that section (for example, § 355) or, as

applicable, the relevant definitional section (for example, § 368).

.02 Rev. Proc. 2026-1. Rev. Proc.

2026-1 is modified and amplified as follows:

(1) Section 6.03. The following text is

added after the first paragraph of section

6.03 of Rev. Proc. 2026-1:

Significant issue rulings. In addition,

the Office of Associate Chief Counsel

(Corporate) may issue a letter ruling on

part of an integrated transaction without ruling on the larger transaction if the

requested ruling would address one or

more issues that: (1) are solely under the

jurisdiction of the Associate Chief Counsel (Corporate); (2) are significant; and

(3) involve the tax consequences or characterization of a transaction (or part of

a transaction) that is described in § 332,

351, 355, 368, or 1036. The Service also

may rule on a particular legal issue under a

section of the Code or related regulations

without ruling on other legal issues under

that section of the Code or regulations if

the issue meets the three conditions of the

preceding sentence.

A significant issue is a germane and

specific issue of law, provided that a ruling on the issue would not be a comfort

Bulletin No. 2026–22

ruling or the conclusion in such a ruling

otherwise would not be essentially free

from doubt. An issue is germane if resolution of the issue is necessary to determine an element of the tax treatment of

the transaction. An issue is specific if it is

the narrowest articulation of the germane

issue. A change of circumstances arising

after a transaction ordinarily does not

present a significant issue with respect to

the transaction.

Before preparing the letter ruling

request under this section 6.03, a taxpayer

should follow the procedures provided in

section 10.07(1) of this revenue procedure

for pre-submission conferences to discuss

whether the Office of the Associate Chief

Counsel (Corporate) will issue a letter

ruling under this section 6.03. The Service reserves the right to rule on any other

aspect of the transaction (including ruling

adversely) if the Service believes doing so

is in the interest of sound tax administration.

All requests for a ruling under this section 6.03 must contain the following:

(1) A narrative description of the transaction that puts the significant issue in

context;

(2) A statement identifying the issue;

(3) An analysis of the relevant law

that sets forth the authorities most closely

related to the issue, explains why these

authorities do not resolve the issue, and

explains why the issue is significant;

(4) Applicable information and representations from relevant revenue procedures with respect to the significant issue

(see Appendix F of this revenue procedure) and as otherwise may be required

by the Office of Associate Chief Counsel

(Corporate) depending on the facts and

circumstances;

(5) If the taxpayer is requesting a ruling

on the tax treatment of part of an integrated

transaction, a representation regarding the

relevant tax consequences of the integrated transaction (to the best knowledge

and belief of the taxpayer), assuming that

the Service issues the requested ruling;

(6) The precise ruling(s) being

requested; and

(7) A statement that no rulings outside

the jurisdiction of the Associate Chief

Counsel (Corporate) are requested.

(2) Appendix C. The following text is

added after question 8 of Appendix C of

Rev. Proc. 2026-1:

See section 6.03.

.03 Rev. Proc. 2026-3. The following

text is added after the first paragraph of

section 4.02(2) of Rev. Proc. 2026-3:

Notwithstanding the prior paragraph,

in connection with transactions described

in § 332, 351, 355, 368, or 1036, the

Office of Associate Chief Counsel (Corporate) may issue a letter ruling on part of an

integrated transaction if and to the extent

that the transaction presents a significant issue. See section 6.03 of Rev. Proc.

2026-1, 2026-1 I.R.B. 1, as modified and

amplified by Rev. Proc. 2026-21, 2026-22

I.R.B. 1538.

SECTION 6. EFFECT ON OTHER

REVENUE PROCEDURES

Rev. Proc. 2026-1 and Rev. Proc.

2026-3 are modified and amplified.

SECTION 7. EFFECTIVE DATE

The significant issue ruling program established by this revenue procedure applies to all letter ruling requests

described in section 4.01 of this revenue

procedure postmarked or, if not mailed,

received by the Service after May 5, 2026.

SECTION 8. PAPERWORK

REDUCTION ACT

The collections of information in this

revenue procedure have been reviewed

and approved by the Office of Management and Budget (OMB) in accordance

with the Paperwork Reduction Act (44

U.S.C. 3507) under control number 15451522.

An agency may not conduct or sponsor,

and a person is not required to respond

to, a collection of information unless the

collection of information displays a valid

OMB control number.

The collections of information in this

revenue procedure are in section 5. This

information is required to determine

whether a taxpayer qualifies for a letter

ruling on part of an integrated transaction

without the Service ruling on the larger

transaction. The collections of information are required to obtain a benefit. The

likely respondents are corporations seeking letter rulings. These procedures do

not change the estimated burden already

approved by OMB.

Books or records relating to a collection of information must be retained as

long as their contents may become material in the administration of any internal

revenue tax law. Generally, tax returns and

tax return information are confidential, as

required by § 6103.

Rev. Proc. 2026-22

SECTION 1. PURPOSE

This revenue procedure provides

indexing adjustments for the applicable dollar amounts under § 4980H(c)(1)

and (b)(1) of the Internal Revenue Code.

These indexed amounts are used to calculate the employer shared responsibility

payments (ESRP) under § 4980H(a) and

(b)(1), respectively.

SECTION 2. ADJUSTED ITEMS

Under § 4980H(c)(5), in the case of

any calendar year after 2014, the applicable dollar amounts of $2,000 and $3,000

under § 4980H(c)(1) and (b)(1), respectively, are increased by an amount equal

to the product of such dollar amount and

the premium adjustment percentage (as

defined in § 1302(c)(4) of the Patient

Protection and Affordable Care Act1) for

increase is rounded to the next lowest

multiple of $10.

The Department of Health and Human

Services (HHS) published the premium

adjustment percentage for 2027 on January 29, 2026, using the most recent

National Health Expenditure Accounts

(NHEA) income and premium data that

was available at the time of publication.

For calculation of the 2027 benefit year

payment parameters, HHS used the NHEA

Projections 2024-2033, the data source

that reflected the most recent projections

available. Using the NHEA Projections

2024-2033, the premium adjustment percentage for 2027 is the percentage (if any)

by which the most recent NHEA projection of per enrollee premiums for private

health insurance (excluding Medigap

and property and casualty insurance) for

2026 ($8,919) exceeds the most recent

NHEA estimate of per enrollee premiums

for private health insurance (excluding

Medigap and property and casualty insurance) for 2013 ($4,715) carried out to

ten significant digits. Using this formula,

the applicable premium adjustment percentage is 1.8916224814.2 For calendar

year 2027, the adjusted $2,000 amount

under § 4980H(c)(1) is $3,780 ($2,000 x

1.8916224814 = $3,783.2449628 rounded

down to $3,780), and the adjusted

$3,000 amount under § 4980H(b)(1)

is $5,670 ($3,000 x 1.8916224814

= $5,674.8674442 rounded down to

$5,670).

(Also: Part 1, §§ 25, 143, 6a.103A-1(b)(4), 6a.103A2(f)(5))

Rev. Proc. 2026-23

SECTION 1. PURPOSE

This revenue procedure provides

issuers of qualified mortgage bonds, as

defined in § 143(a) of the Internal Revenue Code1, and issuers of mortgage credit

certificates, as defined in § 25(c), with (1)

the nationwide average purchase price for

residences located in the United States,

and (2) average area purchase price safe

harbors for residences located in statistical areas in each state, the District of

Columbia, Puerto Rico, the Northern Mariana Islands, American Samoa, the Virgin

Islands, and Guam.

SECTION 2. BACKGROUND

.01 Section 103(a) provides that,

except as provided in § 103(b), gross

income does not include interest on any

State or local bond. Section 103(b)(1) provides that § 103(a) shall not apply to any

private activity bond that is not a “qualified bond” within the meaning of § 141.

Section 141(e) provides, in part, that the

term “qualified bond” means any private

activity bond if such bond (1) is a qualified mortgage bond under § 143, (2) meets

the volume cap requirements under § 146,

and (3) meets the applicable requirements

under § 147.

.02 Section 143(a)(1) provides that the

term “qualified mortgage bond” means a

bond that is issued as part of a qualified

mortgage issue. Section 143(a)(2)(A) provides that the term “qualified mortgage

issue” means an issue of one or more

bonds by a State or political subdivision thereof, but only if: (i) all proceeds

of the issue (exclusive of issuance costs

and a reasonably required reserve) are to

be used to finance owner-occupied res-

idences; (ii) the issue meets the requirements of subsections (c), (d), (e), (f), (g),

(h), (i), and (m)(7) of § 143; (iii) the issue

does not meet the private business tests

of paragraphs (1) and (2) of § 141(b);

and (iv) with respect to amounts received

more than 10 years after the date of issuance, repayments of $250,000 or more of

principal on mortgage financing provided

by the issue are used by the close of the

first semiannual period beginning after the

date the prepayment (or complete repayment) is received to redeem bonds that are

part of the issue.

Average Area Purchase Price

.03 Section 143(e)(1) provides that an

issue of bonds meets the purchase price

requirements of § 143(e) if the acquisition cost of each residence financed by

the issue does not exceed 90 percent of

the average area purchase price applicable

to such residence. Section 143(e)(5) provides that, in the case of a targeted area

residence (as defined in § 143(j)), § 143(e)

(1) shall be applied by substituting 110

percent for 90 percent.

.04 Section 143(e)(2) provides that the

term “average area purchase price” means,

with respect to any residence, the average

purchase price of single-family residences

(in the statistical area in which the residence is located) that were purchased

during the most recent 12-month period

for which sufficient statistical information is available. Under § 143(e)(3) and

(4), respectively, separate determinations

of average area purchase price are to be

made for new and existing residences,

and for two-, three-, and four-family residences.

.05 Section 143(e)(2) also provides that

the determination of the average area purchase price shall be made as of the date

on which the commitment to provide the

financing is made or, if earlier, the date of

the purchase of the residence.

.06 Section 143(k)(2)(A) provides

that the term “statistical area” means (i) a

metropolitan statistical area (MSA), and

(ii) any county (or the portion thereof)

that is not within an MSA. Section

143(k)(2)(C) further provides that if suf-

Unless otherwise specified, all “section” or “§” references are to sections of the Internal Revenue Code or the Temporary Regulations under Title II of the Omnibus Reconciliation Act of

1980 (26 CFR part 6a).

1542

Bulletin No. 2026–22

ficient recent statistical information with

respect to a county (or portion thereof)

is unavailable, the Secretary may substitute another area for which there is sufficient recent statistical information for

such county (or portion thereof). In the

case of any portion of a State which is not

within a county, § 143(k)(2)(D) provides

that the Secretary may designate an area

that is the equivalent of a county. Section

6a.103A-1(b)(4)(i) (issued under § 103A

of the Internal Revenue Code of 1954,

the predecessor of § 143) provides that

the term “State” includes a possession

of the United States and the District of

Columbia.

.07 Section 6a.103A-2(f)(5)(i) provides

that an issuer may rely upon the average

area purchase price safe harbors published

by the Department of the Treasury (Treasury Department) for the statistical area

in which a residence is located. Section

6a.103A-2(f)(5)(i) further provides that an

issuer may use an average area purchase

price limitation different from the published safe harbor if the issuer has more

accurate and comprehensive data for the

statistical area.

Qualified Mortgage Credit Certificate

Program

.08 Section 25(c) permits a State or

political subdivision thereof to establish

a qualified mortgage credit certificate

program. In general, a qualified mortgage

credit certificate program is a program

under which the issuing authority elects

not to issue an amount of private activity

bonds that it may otherwise issue during

the calendar year under § 146, and in its

place, issues mortgage credit certificates

to taxpayers in connection with the acquisition of their principal residences. Section 25(a)(1) provides, in general, that the

holder of a mortgage credit certificate may

claim a federal income tax credit equal to

the product of the credit rate specified

in the certificate and the interest paid or

accrued during the tax year on the remaining principal of the indebtedness incurred

to acquire the residence. Section 25(c)(2)

(A)(iii)(III) generally provides that residences acquired in connection with the

issuance of mortgage credit certificates

must meet the purchase price requirements of § 143(e).

Bulletin No. 2026–22

Income Limitations for Qualified

Mortgage Bonds and Mortgage Credit

Certificates

.09 Section 143(f) imposes limitations

on the income of mortgagors for whom

financing may be provided by qualified

mortgage bonds. In addition, § 25(c)(2)(A)

(iii)(IV) provides that holders of mortgage

credit certificates must meet the income

requirement of § 143(f). Generally, under

§§ 143(f)(1) and 25(c)(2)(A)(iii)(IV),

the income requirement is met only if all

owner-financing under a qualified mortgage bond and all mortgage credit certificates issued under a qualified mortgage

credit certificate program are provided to

mortgagors whose family income is 115

percent or less of the applicable median

family income. Section 143(f)(5), however, generally provides for an upward

adjustment to the percentage limitation

in high housing cost areas. High housing

cost areas are defined in § 143(f)(5)(C) as

any statistical area for which the housing

cost/income ratio is greater than 1.2.

.10 Under § 143(f)(5)(D), the housing cost/income ratio with respect to any

statistical area is determined by dividing

(a) the applicable housing price ratio for

such area by (b) the ratio that the area

median gross income for such area bears

to the median gross income for the United

States. The applicable housing price ratio

is the new housing price ratio (new housing average area purchase price divided

by the new housing average purchase

price for the United States) or the existing housing price ratio (existing housing

average area purchase price divided by the

existing housing average purchase price

for the United States), whichever results

in the housing cost/income ratio being

closer to 1.

Average Area and Nationwide Purchase

Price Limitations

.11 Average area purchase price safe

harbors for each state, the District of

Columbia, Puerto Rico, the Northern Mariana Islands, American Samoa, the Virgin

Islands, and Guam were last published in

Rev. Proc. 2025-18, 2025-19 I.R.B. 1430.

.12 The nationwide average purchase

price was last published in section 4.02 of

Rev. Proc. 2025-18. Guidance with respect

1543

to the United States and area median gross

income figures that are used in computing

the housing cost/income ratio described in

§ 143(f)(5) was published in Rev. Proc.

2021-19, 2021-15 I.R.B. 1008.

.13 This revenue procedure uses Federal Housing Administration (FHA) loan

limits for a given statistical area to calculate the average area purchase price safe

harbor for that area. FHA sets limits on the

dollar value of loans it will insure based on

median home prices and conforming loan

limits established by the Federal Home

Loan Mortgage Corporation. In particular,

FHA sets an area’s loan limit at 95 percent of the median home sales price for

the area, subject to certain floors and caps

measured against conforming loan limits.

.14 To calculate the average area purchase price safe harbors in this revenue procedure, the FHA loan limits are

adjusted to take into account the differences between average and median purchase prices. Because FHA loan limits do

not differentiate between new and existing

residences, this revenue procedure contains a single average area purchase price

safe harbor for both new and existing residences in a statistical area.

.15 The average area purchase price

safe harbors listed in section 4.01 of this

revenue procedure are based on FHA

loan limits released December 11, 2025.

FHA loan limits are available for statistical areas in each state, the District of

Columbia, Puerto Rico, the Northern Mariana Islands, American Samoa, the Virgin

Islands, and Guam. See section 3.03 of

this revenue procedure with respect to

FHA loan limits revised after December

11, 2025.

.16 OMB Bulletin No. 23-01, dated

and effective July 21, 2023, revised the

definitions of the nation’s 935 metropolitan areas. The OMB bulletin no longer

includes primary MSAs.

SECTION 3. APPLICATION

Average Area Purchase Price Safe

Harbors

.01 Average area purchase price safe

harbors for statistical areas in each state,

the District of Columbia, Puerto Rico,

the Northern Mariana Islands, American

Samoa, the Virgin Islands, and Guam are

May 26, 2026

set forth in section 4.01 of this revenue

procedure. Average area purchase price

safe harbors are provided for single-family and two to four-family residences. For

each type of residence, section 4.01 of this

revenue procedure contains a single safe

harbor that may be used for both new and

existing residences. Issuers of qualified

mortgage bonds and issuers of mortgage

credit certificates may rely on these safe

harbors to satisfy the requirements of

§ 143(e) and (f). Section 4.01 of this revenue procedure provides safe harbors for

MSAs and for certain counties and county

equivalents. If no purchase price safe harbor is available for a statistical area, the

safe harbor for “ALL OTHER AREAS”

may be used for that statistical area.

.02 If a residence is in an MSA, the safe

harbor applicable to it is the limitation of

that MSA. If an MSA falls in more than

one state, the MSA is listed in section 4.01

of this revenue procedure under each state.

.03 If the FHA revises the FHA loan

limit for any statistical area after December 11, 2025, an issuer of qualified mortgage bonds or mortgage credit certificates

may use the revised FHA loan limit for that

statistical area to compute (as provided in

the next sentence) a revised average area

purchase price safe harbor for the statistical area provided that the issuer maintains

records evidencing the revised FHA loan

limit. The revised average area purchase

price safe harbor for that statistical area

is computed by dividing the revised FHA

loan limit by 0.860.

.04 If, pursuant to § 6a.103A-2(f)(5)(i),

an issuer uses more accurate and compre-

hensive data to determine the average area

purchase price for a statistical area, the

issuer must make separate average area

purchase price determinations for new

and existing residences. Moreover, when

computing the average area purchase

price for a statistical area that is an MSA,

as defined in OMB Bulletin No. 23-01, the

issuer must make the computation for the

entire applicable MSA. When computing

the average area purchase price for a statistical area that is not an MSA, the issuer

must make the computation for the entire

statistical area and may not combine statistical areas. Thus, for example, the issuer

may not combine two or more counties.

.05 If an issuer receives a ruling permitting it to rely on an average area purchase

price limitation that is higher than the

applicable safe harbor in this revenue procedure, the issuer may rely on that higher

limitation for the purpose of satisfying the

requirements of § 143(e) and (f) for bonds

sold, and mortgage credit certificates

issued, not more than 30 months following the termination date of the 12-month

period used by the issuer to compute the

limitation.

computing the housing cost/income ratio

under § 143(f)(5) regardless of whether

they are relying on the average area purchase price safe harbors contained in this

revenue procedure or using more accurate and comprehensive data to determine

average area purchase prices for new and

existing residences for a statistical area

that are different from the published safe

harbors in this revenue procedure.

.08 If, pursuant to section 6.02 of this

revenue procedure, an issuer relies on the

average area purchase price safe harbors

contained in Rev. Proc. 2025-18, the issuer

must use the nationwide average purchase

price set forth in section 4.02 of Rev. Proc.

2025-18 in computing the housing cost/

income ratio under § 143(f)(5). Likewise,

if, pursuant to section 6.04 of this revenue

procedure, an issuer relies on the nationwide average purchase price published in

Rev. Proc. 2025-18, the issuer must use

the average area purchase price safe harbors set forth in section 4.01 of Rev. Proc.

2025-18 in computing the housing cost/

income ratio under § 143(f)(5).

Nationwide Average Purchase Price

SECTION 4. AVERAGE AREA

AND NATIONWIDE AVERAGE

PURCHASE PRICES

.06 Section 4.02 of this revenue procedure sets forth a single nationwide

average purchase price for purposes of

computing the housing cost/income ratio

under § 143(f)(5).

.07 Issuers must use the nationwide

average purchase price set forth in section 4.02 of this revenue procedure when

.01 Average area purchase prices for

single-family and two to four-family residences in MSAs, and for certain counties and county equivalents are set forth

below. The safe harbor for “ALL OTHER

AREAS” (found at the end of the table

below) may be used for a statistical area

that is not listed below.

ratio for new and existing residences) is

$553,900.

SECTION 5. EFFECT ON OTHER

DOCUMENTS

Rev. Proc. 2025-18 is obsolete except

as provided in section 6 of this revenue

procedure.

SECTION 6. EFFECTIVE DATES

.01 Issuers may rely on this revenue

procedure to determine average area purchase price safe harbors for commitments

to provide financing or issue mortgage

credit certificates that are made, or (if

the purchase precedes the commitment)

for residences that are purchased, in the

period that begins on May 6, 2026, and

ends on the date as of which the safe harbors contained in section 4.01 of this revenue procedure are rendered obsolete by a

new revenue procedure.

.02 Notwithstanding section 5 of this

revenue procedure, issuers may continue

to rely on the average area purchase price

safe harbors contained in Rev. Proc. 202518, with respect to bonds sold, or for mortgage credit certificates issued with respect

to bond authority exchanged, before June

5, 2026, if the commitments to provide

financing or issue mortgage credit certificates are made on or before July 6, 2026.

.03 Except as provided in section 6.04,

issuers must use the nationwide average

purchase price limitation contained in this

Bulletin No. 2026–22

revenue procedure for commitments to

provide financing or issue mortgage credit

certificates that are made, or (if the purchase precedes the commitment) for residences that are purchased, in the period

that begins on May 6, 2026 and ends on

the date when the nationwide average purchase price limitation is rendered obsolete

by a new revenue procedure.

.04 Notwithstanding sections 5 and

SECTION 7. PAPERWORK

REDUCTION ACT

The collection of information contained in this revenue procedure has been

reviewed and approved by the Office of

Management and Budget in accordance

with the Paperwork Reduction Act (44

U.S.C. 3507) under control number 15451877.

An agency may not conduct or sponsor,

and a person is not required to respond

to, a collection of information unless the

collection of information displays a valid

OMB control number.

This revenue procedure contains a collection of information requirement in section 3.03. The purpose of the collection

1555

of information is to verify the applicable

FHA loan limit that issuers of qualified

mortgage bonds and qualified mortgage

certificates have used to calculate the

average area purchase price for a given

MSA for purposes of §§ 143(e) and 25(c).

The collection of information is required

to obtain the benefit of using revisions to

FHA loan limits to determine average area

purchase prices. The likely respondents

are state and local governments.

The estimated total annual reporting

and/or recordkeeping burden is: 15 hours.

The estimated annual burden per

respondent and/or recordkeeper: 15 minutes.

The estimated number of respondents

and/or recordkeepers: 60.

Books or records relating to a collection of information must be retained as

long as their contents may become material in the administration of any internal

revenue law. Generally, tax returns and

tax return information are confidential, as

required by 26 U.S.C. 6103.

SECTION 8. DRAFTING

INFORMATION

The principal author of this revenue

procedure is Brian Choi of the Office of

Associate Chief Counsel (Financial Institutions & Products). For further information regarding this revenue procedure

contact Mr. Choi on (202) 317-3154 (not a

toll-free number).

Definition of Terms

Revenue rulings and revenue procedures

(hereinafter referred to as “rulings”) that

have an effect on previous rulings use the

following defined terms to describe the

effect:

Amplified describes a situation where

no change is being made in a prior published position, but the prior position is

being extended to apply to a variation of

the fact situation set forth therein. Thus,

if an earlier ruling held that a principle

applied to A, and the new ruling holds that

the same principle also applies to B, the

earlier ruling is amplified. (Compare with

modified, below).

Clarified is used in those instances

where the language in a prior ruling is

being made clear because the language

has caused, or may cause, some confusion. It is not used where a position in a

prior ruling is being changed.

Distinguished describes a situation

where a ruling mentions a previously published ruling and points out an essential

difference between them.

Modified is used where the substance

of a previously published position is being

changed. Thus, if a prior ruling held that a

principle applied to A but not to B, and the

new ruling holds that it applies to both A

and B, the prior ruling is modified because

it corrects a published position. (Compare

with amplified and clarified, above).

Obsoleted describes a previously published ruling that is not considered determinative with respect to future transactions.

This term is most commonly used in a ruling

that lists previously published rulings that

are obsoleted because of changes in laws or

regulations. A ruling may also be obsoleted

because the substance has been included in

regulations subsequently adopted.

Revoked describes situations where the

position in the previously published ruling

is not correct and the correct position is

being stated in a new ruling.

Superseded describes a situation where

the new ruling does nothing more than

restate the substance and situation of a

previously published ruling (or rulings).

Thus, the term is used to republish under

the 1986 Code and regulations the same

position published under the 1939 Code

and regulations. The term is also used

when it is desired to republish in a single

ruling a series of situations, names, etc.,

that were previously published over a

period of time in separate rulings. If the

new ruling does more than restate the substance of a prior ruling, a combination of

terms is used. For example, modified and

superseded describes a situation where the

substance of a previously published ruling

is being changed in part and is continued

without change in part and it is desired to

restate the valid portion of the previously

published ruling in a new ruling that is

self contained. In this case, the previously

published ruling is first modified and then,

as modified, is superseded.

Supplemented is used in situations in

which a list, such as a list of the names of

countries, is published in a ruling and that

list is expanded by adding further names

in subsequent rulings. After the original

ruling has been supplemented several

times, a new ruling may be published that

includes the list in the original ruling and

the additions, and supersedes all prior rulings in the series.

Suspended is used in rare situations

to show that the previous published rulings will not be applied pending some

future action such as the issuance of new

or amended regulations, the outcome of

cases in litigation, or the outcome of a

Service study.
