The IRS Mission
Provide America’s taxpayers top-quality service by helping

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 Unpublished rulings will not be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.

Bulletin No. 2021–25

Part I
Section6621.—
Determination of Rate of
Interest
26CFR301.6621-1: Interest rate.

Rev.Rul.2021-10
Section 6621 of the Internal Revenue
Code establishes the interest rates on overpayments and underpayments of tax. Under section 6621(a)(1), the overpayment
rate is the sum of the federal short-term
rate plus 3 percentage points (2 percentage
points in the case of a corporation), except the rate for the portion of a corporate
overpayment of tax exceeding $10,000 for
a taxable period is the sum of the federal short-term rate plus 0.5 of a percentage
point. Under section 6621(a)(2), the underpayment rate is the sum of the federal
short-term rate plus 3 percentage points.
Section 6621(c) provides that for purposes of interest payable under section
6601 on any large corporate underpayment, the underpayment rate under section
6621(a)(2) is determined by substituting
“5 percentage points” for “3 percentage
points.” See section 6621(c) and section
301.6621-3 of the Regulations on Procedure and Administration for the definition of a large corporate underpayment
and for the rules for determining the applicable date. Section 6621(c) and section 301.6621-3 are generally effective for
periods after December 31, 1990.
Section 6621(b)(1) provides that the
Secretary will determine the federal short-

June 21, 2021

term rate for the first month in each calendar quarter. Section 6621(b)(2)(A)
provides that the federal short-term rate
determined under section 6621(b)(1) for
any month applies during the first calendar quarter beginning after that month.
Section 6621(b)(3) provides that the federal 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 2021 is the rate published in Revenue
Ruling 2021-8, 2021-18 IRB 1120, to take
effect beginning May 1, 2021. The federal
short-term rate, rounded to the nearest full
percent, based on daily compounding determined during the month of April 2021
is 0 percent. Accordingly, an overpayment
rate of 3 percent (2 percent in the case of a
corporation) and an underpayment rate of
3 percent are established for the calendar
quarter beginning July 1, 2021. The overpayment rate for the portion of a corporate
overpayment exceeding $10,000 for the
calendar quarter beginning July 1, 2021

1202

is 0.5 percent. The underpayment rate for
large corporate underpayments for the calendar quarter beginning July 1, 2021, is
5 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 3 percent rate also applies to estimated tax underpayments for the third calendar quarter
beginning July 1, 2021. In addition, pursuant to section 6603(d)(4), the rate of interest on section 6603 deposits is 0 percent
for the third calendar quarter in 2021.
Interest factors for daily compound interest for annual rates of 0.5 percent are
published in Appendix A of this Revenue
Ruling. Interest factors for daily compound interest for annual rates of 2 percent, 3 percent and 5 percent are published
in Tables 9, 11, and 15 of Rev. Proc. 95-17,
1995-1 C.B. 563, 565, and 569.
Annual interest rates to be compounded
daily pursuant to section 6622 that apply
for prior periods are set forth in the tables
accompanying this revenue ruling.

ruling is Casey R. Conrad of the Office of

and Administration). For further information regarding this revenue ruling, contact

Bulletin No. 2021–25

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.
