Plaintiffs,
v.
OPINION & ORDER
UNITED STATES OF AMERICA, et al.,
Defendants.
CECCHI, District Judge.
Before the Court is the motionof the United States of America, Secretary of the Treasury,
Department of the Treasury, Commissioner of Internal Revenue, and Internal Revenue Service
(“Defendants”) to dismiss (ECF No. 33; see also ECF No. 33-1 (“Br.”)) the second amended
complaint of plaintiffs Sherry L. Sims and Marcia Brown (“Plaintiffs”). ECF No. 24 (“SAC”).
Plaintiffs opposed the motion and filed a cross motion for summary judgment. ECF No. 36
(“Opp.”); ECF No. 42. Defendants replied on their motion to dismiss and opposed the cross
motion. ECF No. 57. Plaintiffs then repliedon their crossmotion. ECF No. 60. Having reviewed
the papers and determining that this matter can be resolved entirely on the motion to dismiss,1 the
Court will address that motion only. The Court decides this matter without oral argument pursuant
to Federal Rule of Civil Procedure 78. For the reasons set forth below, Defendants’ motion to
dismiss is granted.
I. BACKGROUND
1 Given the competing motions with differing standards of review, the Court directed the parties
to advise the Court as to whether the motions should be addressed at the same time or in sequence.
ECF No. 69. Defendants contend that deciding their motion to dismiss first would be most
efficient, as the motion for summary judgment would be mooted if the Court is inclined to grant
the motion to dismiss. ECF No. 70. Plaintiffs do not oppose proceeding with the motion to dismiss
first. ECF No. 71.
Plaintiffsbring this action to challengethe constitutionality ofa limitimposed by Congress
on the federalincometaxdeductionfor state and local taxes (the “SALT Deduction”). SAC ¶ 67.
These claims largely mirror those rejected by the Second Circuit in a similar constitutional
challenge. See New York v. Yellen, 15 F.4th 569 (2d Cir. 2021), cert. denied, 142 S. Ct. 1669 (Apr.
18, 2022).
A. History of the Federal Income Tax and SALT Deduction
Article I of the U.S. Constitution provides Congress with the power to “lay and collect
Taxes, Duties, Imposts and Excises.” U.S. Const. art. I, § 8, cl. 1. The federal government,
however, did not enact the first federal income tax until 1861. Yellen, 15 F.4th at 572 (citation
omitted). With this law, Congress provided that “in estimating [taxable] income, all national, state,
or local taxes assessed upon the property, from which the income is derived, shall be first
deducted.” State of New York v. Mnuchin, 408 F. Supp. 3d 399, 403 (S.D.N.Y. 2019) (alteration
in original) (citation omitted). This provision—the SALT Deduction—remained largely
unchanged for the next decade even as Congress amended theincome tax code multiple timesuntil
the income tax lapsed in 1872. Id. (citations omitted).
In 1894, Congress reinstated federal income taxes and with it, the SALT Deduction.
Yellen, 15 F.4th at 573 (citation omitted). One year later, however, the Supreme Court declared
that the 1894 tax law violated Article I, Section 9 of the Constitution, which provided that “no . . .
direct[] Tax shall be laid, unless in Proportion to the Census,” because the federal income tax was
a “direct” tax that was not apportioned according to the states’ relative populations. Id. (citing
Pollock v. Farmers’ Loan & Tr. Co., 158 U.S. 601, 637 (1895) and U.S. Const. art. I, § 9, cl. 4).
In the wake of this decision, Congress proposed a constitutional amendment to eliminate
the apportionment requirement for direct taxes, including taxes on income. Mnuchin, 408 F. Supp.
3d at 404. The Sixteenth Amendment, ratified in 1913, provides Congress withthe power to “lay
and collect taxes on incomes, from whatever source derived, without apportionment among the
several States.” U.S. Const. amend. XVI. Shortly thereafter, Congress reimplemented the federal
income tax, which included the SALT Deduction. Yellen. 15 F.4th at 573 (citation omitted). From
1913 to the present, some form of the SALT Deduction “has been a mainstay of the federal Tax
Code.” Mnuchin, 408 F. Supp. 3d at 404.
Despite its durability, Congress has repeatedly altered the SALT Deduction. Yellen, 15
F.4th at 573. In 1944, Congress introduced the standardized deduction, which meant that the
SALT Deduction was relevant only to those who chose to itemize their tax deductions. Mnuchin,
408 F. Supp. 3d. at 404 (citation omitted). In 1964, Congress specifically “enumerated the types
of [state and local] taxes that were deductible and disallowed a deduction for any other state and
local taxes,” departing from the previous rule that “all state and local taxes were deductible unless
specifically disallowed.” Id. at 404–05 (quoting Gladriel Shobe, Disaggregating the State and
Local Tax Deduction, 35 Va. Tax Rev. 327, 338 (2016)). In 1986, Congress implemented an
alternative minimum tax schemewhich, if applicable, would preclude use of the SALT Deduction.
Yellen, 15 F.4th at 573–74 (citation omitted). Along with this change, Congress prevented
taxpayers from deducting state and local sales taxes. Id. at 574. In 1990, Congress passed the
“Pease limitation,” which required taxpayerswith adjusted gross incomes above certain thresholds
to reduce the totals claimed in itemized deductions, including any SALT Deductions, by as much
as eighty percent. Id.(citation omitted). And in 2004, Congress reinstatedthe deduction for sales
taxes but made taxpayers choose between deducting sales or income taxes, which led to fewer
taxpayers deducting state and local income taxes. Id. (citation omitted).
Then, in 2017, Congress passed the Tax Cuts and Jobs Act (the “2017 Tax Act”). Pub.
L. No. 115-97, 131 Stat. 2054; see also SAC ¶¶ 1–2. As relevant to this matter, section 11042 of
the 2017 Tax Act limited the SALT Deduction to “$10,000 ($5,000 in the case of a married
individual filing a separate return).” 2017 Tax Act § 11,042, 131 Stat. at 2085–86 (codified at 26
U.S.C. § 164(b)(6)) (the “SALT Deduction Cap” or “Cap”). Plaintiffs bring this action to
challenge the constitutionality of the SALT Deduction Cap.
B. The Complaint
In addition to describing the history of the SALT Deduction, the SAC asserts that the SALT
Deduction Cap was intended to coerce high-tax states into changing their fiscal policies. SAC ¶¶
29, 53–54. Plaintiffs cite statements made by various Congressmen and Executive officials
suggesting that the Cap would impose a greater burden on high-tax states. Id. ¶¶ 31, 39, 42.
Plaintiffs further allege that the SALT Deduction Cap did harm high-tax states. In particular, they
assert that states such as Illinois, New Jersey, and New York have experienced population declines
that are directly attributable to this enactment. Id. ¶¶ 59–62.
Plaintiffs raise ten counts in the SAC, alleging that the SALT Deduction Cap is
unconstitutional on various grounds. The first nine counts assert violations of the (1) Tenth
Amendment; (2) Privileges and Immunities Clause of Article IV; (3) Ninth Amendment; (4) Full
Faith and Credit Clause of Article IV and Preamble to the Constitution; (5) “Reciprocal Immunity
Doctrine”; (6) Republican Guarantee Clause of Article IV; (7) constitutional principles of
federalism; and (8) and (9) Sixteenth Amendment. Id. ¶¶ 71–166. In Count Ten, Plaintiffs seek
a declaratory judgment that the SALT Deduction Cap is unconstitutional and request a tax refund
for the 2018 and 2019 tax years. Id. ¶ 167–70. Defendants now move to dismiss all counts for
failure to state a claim.2 ECF No. 33.
II. LEGAL STANDARD
To survive dismissal under Federal Rule of Civil Procedure 12(b)(6), “a complaint must
contain sufficient factual matter . . . to ‘state a claim to relief that is plausible on its face.’” Ashcroft
v. Iqbal, 556 U.S. 662, 678 (2009) (citations omitted). A claim is facially plausible when supported
by “factual content that allows the court to draw the reasonable inference that the defendant is
liable for the misconduct alleged.” Id. A complaint that contains “a formulaic recitation of the
elements of a cause of action” supported by mere conclusory statements or offers “‘naked
assertion[s]’ devoid of ‘further factual enhancement’” will not suffice. Id. (citation omitted). In
evaluating the sufficiency of a complaint, the court accepts all factual allegations as true, draws all
reasonable inferences in favor of the non-moving party, and disregards legal conclusions. Phillips
v. Cnty. of Allegheny, 515 F.3d 224, 231–34 (3d Cir. 2008).
III. DISCUSSION
A. Tenth Amendment and Federalism Claims (Counts One and Seven)
In Count One, Plaintiffs assert that the SALT Deduction Cap violates the Tenth
Amendment, SAC¶¶71–96, which provides that “[t]he powers not delegated to the United States
by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to
the people.” U.S. Const. amend. X. In Count Seven, Plaintiffs allege that the Cap violates
constitutional principles of federalism. SAC ¶¶ 147–53. The Court will consider these Counts in
tandem, asthe Supreme Court has instructed that arguments raised under the “Tenth Amendment”
2 Defendants also move to dismiss Counts Four and Six as to the 2018 refund claim, but not the
2019 refund claim, for lack of jurisdiction. Br. at 8–11.
“encompass any implied constitutional limitation on Congress’ authority to regulate state
activities, whether grounded in the Tenth Amendment itself or in principles of federalism derived
generally from the Constitution.” See South Carolina v. Baker, 485 U.S. 505, 511 n.5 (1988); see
also City of Phila. v. Sessions, 280 F. Supp. 3d 579, 647 (E.D. Pa. 2017) (“[T]he Tenth Amendment
embodies the principle of Federalism that pervades the Constitution. Thus, courts frequently cite
to the Tenth Amendment as a placeholder for Federalism concerns.”).
i. Congress Has the Power to Tax Income and Define Deductions
Where a power is delegated to Congress, the Tenth Amendment expressly disclaims the
reservation of that power to the states. New York v. United States, 505 U.S. 144, 156 (1992). The
Constitution grants Congress the power to impose taxes, including direct income taxes. U.S.
Const. art. I, § 8, cl. 1 & amend. XVI; see also G.M. Leasing Corp. v. United States, 429 U.S. 338,
354 (1977) (noting that the taxation power “is a specifically enunciated power of the Federal
Government”). Moreover, “Congress has unquestioned power to condition, limit, or deny
deductions from gross income.” Alpenglow Botanicals, LLC v. United States, 894 F.3d 1187, 1200
(10th Cir. 2018) (citation omitted); see also INDOPCO, Inc. v. C.I.R., 503 U.S. 79, 84 (1992)
(recognizing that an “income tax deduction is a matter of legislative grace” (citation omitted)).
Thus, Congress acted within its delegated taxing authority when limiting the SALT Deduction.
ii. Plaintiffs’ Arguments in Defense of this Claim Lack Merit
Plaintiffs’ arguments that the SALT Deduction Cap violates the Tenth Amendment or
principles of federalism lack merit. First, they contend that “States’ sovereign power of taxation
cannot be abridged or suspended in whole or in part by the use of federal power to tax.” SAC ¶
76. Plaintiffs argue that federal legislation cannot “hinder or limit” the states’ sovereign right to
tax its citizens, but do not explain how a cap on a deduction available to individual taxpayers
interferes with the states’ own taxing powers. Opp. at 4–7. Nothing about the Cap limits the
states’ abilities to pursue any particular tax policy. See Yellen, 15 F.4th at 582–83 (finding
unpersuasive the plaintiff-states’ argument that the SALT Deduction Cap “unconstitutionally
infringes on state sovereignty” by “coerc[ing] them to abandon their preferred fiscal policies”).
Second, Plaintiffs assert that the Tenth Amendment “reserves to the States the taxing
powers that existed prior to the adoption of the Constitution.” See SAC ¶ 75. They contend that
the “States had full rights to levy taxes under the Articles of Confederation that preceded our
Constitution.” Id. ¶ 77; see also Opp. at 11. Plaintiffs add that the states have a “sovereign[] right
to have priority” and “primacy” with respect to taxes because the states’ right to tax came first and
predated the Constitution. Opp. at 11. The Constitution, however, “greatly changed” the
allocation of taxing powers that existed under the Articles of Confederation. Lane Cnty. v. State
of Oregon, 74 U.S. 71, 77 (1868). Whereas under the Articles the states maintained the “whole
power of direct and indirect taxation of persons and property,” the Constitution “gave the power
to tax, both directly and indirectly, to the [federal] government.” Id. at 76–77. Thus, the Tenth
Amendment did not reserve to the states the taxing power existing prior to the Constitution, as the
Constitution affirmatively allocated these powers to the federal government. Id.at 77 (noting that
the power to tax was given to the federal government, subject to only limited exceptions, “without
any express reservation”).
Third, Plaintiffs assert that “SALT revenues” were not taxed as part of the earliest income
taxes and that Congress maintained the SALT Deduction from the passage of the first income tax
under the Sixteenth Amendment in 1913 through 2017. SAC ¶¶ 85–91; see also Opp. at 13. But
Congress has repeatedly altered the SALT Deduction since the passage of the Sixteenth
Amendment, and this legislative history shows that Congress has not “view[ed] its authority to
limit the SALT deduction as subject to any relevant constitutional constraints.” Yellen, 15 F.4th
at 581–82. Moreover, Plaintiffs’ citation to statements by various members of congress, see SAC
¶¶ 22–24, 26–27, does not undermine this point. Yellen, 15 F.4th at 581–82 (noting that such
statements “have over time been drowned out by the overall statutory history of the deduction,”
which does not reflect that Congress believed thatthe deduction was required by the Constitution).
Therefore, history does not show that the SALT Deduction is constitutionally compelled by
principles of federalism.
Fourth, Plaintiffs argue that the SALT Deduction Cap is an unconstitutional use of
Congress’s taxing power to impose a regulatory penalty. Opp. at 8–10. Congress may not use its
taxing power to “adopt[] the criteria of wrongdoing” and then impose a tax on those who do not
comply. See Bailey v. Drexel Furniture Co., 259 U.S. 29, 38 (1922) (striking down a “so-called
tax” that was primarily meant to deter child labor). But the SALT Deduction is not a tax. See
Yellen, 15 F.4th at 572 (describing the SALT Deduction as allowing “taxpayers to deduct from
their taxable income” (emphasis added)). Moreover, income tax deductions are not available by
right but instead are afforded to taxpayers only by the grace of Congress. INDOPCO, 503 U.S. at
84. Accordingly, the Cap cannot be a regulatory penalty.
Fifth, Plaintiffs allegethat the SALT Deduction Cap was meant “to make States lower their
taxes and the necessary public services they provide.” SAC ¶ 65. This appears to implicate the
anticommandeering doctrine, see Br. at 13–16, which instructs that “Congress may not simply
commandeer the legislative processes of the States by directly compelling them to enact and
enforce a federal regulatory program.” Murphy v. Nat’l Collegiate Athletic Ass’n, 584 U.S. 453,
472 (2018) (citation modified) (quoting New York, 505 U.S. at 161).
TheSALT DeductionCap does not violate this doctrine, as it does not directly compel the
states to do anything. See id. at 475 (recognizing that in Baker, a law altering the tax treatment of
state-issued bonds “did not order the States to enact or maintain any existing laws” and thus did
not directly compel the states to act). Instead, “it simply ha[s] the indirect effect of pressuring
States to” alter their tax policies. Id. For example, a state may opt to lower taxes so that their
residents do not pay in excess of the SALT Deduction Cap, thereby incentivizing resident
taxpayers to remain in the state. But nothing about the Cap compels any state to do anything at
all. See id. at 474 (holding that a federal statute that prohibited states from authorizing sports
gambling violated the anticommandeering doctrine because it “unequivocally dictate[d] what a
state legislature may and may not do”). Accordingly, the SALT Deduction Cap does not violate
the anticommandeering principle.
Sixth, Plaintiffs allege that the SALT Deduction Cap “is intended to interfere with many
States’ sovereign authority to determine their fiscal policies.” SAC ¶¶ 92–93. Congress may use
its taxing and spending powers to encourage the states to regulate in a particular way, including
by using financial incentives to influence states’ policy choices. Yellen, 15 F.4th at 582 (2d Cir.
2021) (citing New York, 505 U.S. at 166). Where this “pressure turns into compulsion,” however,
such action may infringe upon state sovereignty and violate principles of federalism by “indirectly
coerc[ing] a State to adopt a federal regulatory system as its own.” Nat’l Fed’n of Indep. Bus. v.
Sebelius, 567 U.S. 519, 577–78 (2012) (“NFIB”). But the Supreme Court has only found such
coercion once: NFIB. Yellen, 15 F.4th at 582. Under the Affordable Care Act, states that opted
out of the expansion of health care coverage under Medicaid stood to lose both newly appropriated
Medicaid funding as well as all of their existing federal Medicaid funding. NFIB, 567 U.S. at 581.
The Court recognized that this amounted to a potential 10 percent loss of a state’s budget, leaving
the state with “with no real option but to acquiesce in the Medicaid expansion.” Id. at 581–82.
The Court thus concluded that such a significant financial incentive was unconstitutionally
coercive. Id.
Turning to Plaintiffs’ claims here, they assert that “[e]xperts expect New Jersey and New
York real estate to lose value as a result” of the SALT Deduction Cap. SAC ¶ 56. They add that
several high-tax states did lose citizens to migration between the passage of the 2017 Tax Act and
2020 because citizens had an incentive to move to low-tax states. Id. ¶¶ 60–62, 65. But these
assertions do not show that state tax revenues will decrease so significantly that the SALT
Deduction Cap would “exert such undue pressure as to raise a genuine constitutional concern.”
Yellen, 15 F.4th at 583 (citing NFIB, 567 U.S. at 581). In fact, even in Yellen, where the court had
allegations of specific estimated tax revenue losses for the plaintiff-states as a result of the Cap,
the court found that the approximate “quantitative losses constitute[ed] such a small portion of a
State’s budget” so as to not amount to federal coercion. Id. (citing NFIB, 567 U.S. at 581).
Therefore, the SAC fails to show that the SALT Deduction Cap is unconstitutionally coercive. As
all of Plaintiffs’ arguments in defense of Counts One and Seven are unpersuasive, Defendants’
motion to dismiss these claims is granted.
B. Privileges and Immunities Clause of Article IV (Count Two)
In Count Two, Plaintiffs assert that the SALT Deduction Cap violates the Privileges and
Immunities Clause of Article IV because it discriminates against citizens of high-tax states. SAC
¶¶ 97–102. This provision states that “[t]he Citizens of each State shall be entitled to all Privileges
and Immunities of Citizens in the several States.” U.S. Const. art. IV, § 2, cl. 1.
The Privileges and Immunities Clause, however, is inapplicable to the challenged action.
This Clause was intended “to foster a national union by discouraging discrimination against
residents of another state on the basis of citizenship.” Yerger v. Mass. Turnpike Auth., 395 F.
App’x 878, 885 (3d Cir. 2010) (citation omitted); see alsoLutz v. City of York, Pa., 899 F.2d 255,
262 (3d Cir. 1990) (“[T]he purpose of the [Privileges and Immunities Clause] was simply ‘to insure
to a citizen of State A who ventures into State B the same privileges which the citizens of State B
enjoy.’” (quoting Toomer v. Witsell, 334 U.S. 385, 395 (1948))). It therefore imposes a limit on
state power, not federal power. Pollack v. Duff, 793 F.3d 34, 41 (D.C. Cir. 2015) (noting that the
Supreme Court “has [n]ever held [that] an action taken by any branch of the federal government
is subject to scrutiny under the Privileges and Immunities Clause of Article IV”); see also Laws.
for Fair Reciprocal Admission v. United States, No. 22-2399, 2023 WL 145530, at *9 (D.N.J. Jan.
10, 2023) (“The federal government is simply not subject to scrutiny under the Privileges and
Immunities Clause of Article IV.”). Plaintiffs challenge a federal action, and therefore, the
Privileges and Immunities Clause of Article IV does not apply.
Plaintiffs contend that the original intent of the Clause was actually to “protect against
federal action.” Opp. at 18–19, 25–27. Theframers’intent, however, was to remedy “the practice
of some States denying to outlanders the treatment that its citizens demanded for themselves.”
Austin v. New Hampshire, 420 U.S. 656, 660–61 (1975). Thus, contrary to Plaintiffs’ argument,
the intent of the Clause was to address discrimination by the states, not the federal government.
Plaintiffs additionally cite Barron v. City of Baltimore, 32 U.S. 243 (1833), to argue that
the Clause was intended to restrain federal action. Opp. at 17–18. They contend that Barron
stands for the proposition that constitutional clauses intended to limit state power specifically say
so, and that the absence of “no state shall” from a clause indicates that it applies to the federal
government. Id. at 17. Barron, however, merely held that the prohibitions in Article I, Section 10
expressly applied to the states because they affirmatively provided that “no state shall” take any
of the listed actions. 32 U.S. at 248–49. The Court did not hold that all of the Constitution’s
restrictions on state power categorically include the language “no state shall.” In fact, Barronalso
explains that the location of a clause within the Constitution is relevant to whether it appliesto the
state or federal governments. Id. at 248 (noting that certain prohibitions on state power are
“brought together in the same section”). And the location of the Privileges and Immunities Clause
cuts against Plaintiffs’ position:
If the Privileges and Immunities Clause applied to the federal government, then we
might expect to find it in Article I, § 9, alongside other limitations upon the powers
of the Congress to discriminate against residents of certain states, such as the Export
Taxation Clause and the Port Preference Clause; in any case, it would not be in
Article IV
Pollack, 793 F.3d at 44. Thus, Barron does not demonstrate that the Clause limits federal power.
Because the Privileges and Immunities Clause has no application to the challenged federal
action, the Court need not address Plaintiffs’ other arguments as to why the action violated the
Clause. Accordingly, Defendants’ motion to dismiss Count Two is granted.
C. Ninth Amendment (Count Three)
In Count Three, Plaintiffs assert that the SALT Deduction Cap violates the Ninth
Amendment by disparaging the rights of citizens to be free from arbitrary or discriminatory taxes
on phantom income3 and double taxation.4 SAC ¶¶ 103–113. The Ninth Amendment provides
that “[t]he enumeration in the Constitution, of certain rights, shall not be construed to deny or
3 “Phantom income” occurs when a “taxpayer receives taxable income but does not presently
receive cash or other tangible economic benefits.” Timothy M. Todd, Phantom Income and
Domestic Support Obligations, 67 Buff. L. Rev. 365, 376–77 (2019). It requires someone to “pay
taxes on something without receiving . . . any commensurate asset with which to pay those taxes.”
Id. at 377. For example, a partnership does not pay income taxes at the entity level. Id. Rather,
the net income of the partnership is allocated to each partner, who then report their allocated
income on their own tax returns and pay the taxes individually. Id. Although the partnership may
have a positive net income, and thus the partners report receiving a positive net income for tax
purposes, that does not necessarily mean that the partners actually received their allocated net
income in cash through a distribution. Id. Instead, the partnership may have reinvested that
income into the business. Id. at 377–78. In this situation, the partners are said to have received
“phantom income,” because while they must report on their individual taxes that they had positive
net income, they did not actually receive the cash distribution on which to pay the corresponding
income tax. Id. at 378.
Plaintiffs assert that “state taxes deducted and withheld from their income” by New Jersey and
“real estate taxes” paid to New Jersey constitute “phantom income” because the “Plaintiffs have
never received the benefit of that income.” SAC ¶ 69; see also id. ¶ 129 (“The income withheld
by operation of law by the State in which the taxpayer resides is income the taxpayer does not
physically receive, i.e., phantom income.”). Plaintiffs further argue that these taxes are phantom
income because the “taxpayer did not keep or possess [the sums] paid to the state” or the sums
were “never received [because they were] withheld.” Opp. at 2. There are two flaws in Plaintiffs’
argument. First, that Plaintiffs did not keep the sums paid to the state in taxes says nothing about
whether they received the corresponding assets on which they paid the taxes. By Plaintiffs’
definition, all state and local taxes would constitute phantom income just by virtue of an individual
having to pay the taxes at all. Second, that Plaintiffs had certain taxes withheld from paychecks
by the state does not mean that they never received the benefit of that income. Tax withholdings
allow an individual to pay the commensurate portion of income tax with every paycheck, rather
than paying all of one’s income tax one time a year. See Tax Withholding for Individuals,
https://www.irs.gov/individuals/employees/tax-withholding (last visited Apr. 13, 2026). But
unlike true “phantom income,” an individual whose taxes are withheld from a paycheck still
receives the income that is subject to taxation. Because Plaintiffs’ argument misconstrues the
nature of “phantom income,” their assertion that the SALT Deduction Cap leads to a tax on
phantom income lacks merit.
4Plaintiffs assert that “[d]ouble taxation exists when the taxpayer has paid taxes to the state where
he resides and then pays federal taxes on the same money he has already paid the state.” Opp. at
15. According to Plaintiffs, Congress not providing an unlimited SALT Deduction constitutes
double taxation and is unconstitutional. Id. at 27–28. The cases Plaintiffs cite to support this
position, however, involve challenges to state (not federal) taxes based on the interstate commerce
clause. See Comptroller of the Treasury of Md. v. Wynne, 575 U.S. 542 (2015); Complete Auto
Transit v. Brady, 430 U.S. 274 (1977); Cent. Greyhound Lines, Inc., of N.Y. v. Mealey, 334 U.S.
disparage others retained by the people.” U.S. Const. amend. IX. But this amendment “does not
independently provide a source of individual constitutional rights.” Perry v. Lackawanna Cnty.
Children & Youth Servs., 345 F. App’x 723, 726 (3d Cir. 2009) (citations omitted). Rather than
providing any substantive rights, courts interpret the Ninth Amendment as a rule of construction.
Soder v. Chenot, No. 06-1522, 2007 WL 1098970, at *4 (M.D. Pa. Apr. 11, 2007) (citation
omitted); see also Cousar v. Morgan, No. 21-14517, 2021 WL 5918474, at *5 (D.N.J. Dec. 15,
2021) (“The Ninth Amendment is not a source of rights as such; it is simply a rule about how to
read the Constitution.” (citation omitted)). Any claim arising under the Ninth Amendment
accordingly fails as a matter of law. Fennimore v. Lower Twp., No. 09-2090, 2011 WL 1705599,
at *4 n.5 (D.N.J. May 4, 2011). Therefore, Defendants’ motion to dismiss Count Three is granted.
D. Full Faith and Credit Clause of ArticleIVand thePreamble (Count Four)
In Count Four,5 Plaintiffs assert that the SALT Deduction Cap violates the Full Faith and
Credit Clause of Article IV and the Preamble to the U.S. Constitution. SAC ¶ 114–122. The Full
653 (1948); Gwin, White & Prince v. Henneford, 305 U.S. 434 (1939); J.D. Adams Mfg. Co. v.
Storen, 304 U.S. 307 (1938); Armco Inc. v. Hadesty, 467 U.S. 638 (1984); Container Corp. of Am.
v. Franchise Tax Bd., 463 U.S. 159 (1983); Tyler Pipe Indus., Inc. v. Wash. State Dep’t of Revenue,
483 U.S. 232 (1987). These authorities do not support Plaintiffs’ assertion that subjecting an
individual to federal and state taxes on the same income constitutes “double taxation.” Plaintiffs
thus fail to provide any legal support for their double taxation argument.
5In addition to contending that Plaintiffs fail to state a claim here, Defendants argue that the Court
lacks jurisdiction to consider Count Four as to Plaintiffs’ 2018 tax refund claim (but nottheir2019
claim) based on the “variance doctrine.” Br. at 9–11. This doctrine bars a taxpayer from “raising
in a refund suit grounds for recovery which have not previously been set forth in its
[administrative] claim for a refund” before the Internal Revenue Service. Shadoan v. United
States, No. 12-2538, 2021 WL 5235112, at *5 (S.D. Ind. Nov. 8, 2021) (citation omitted)). Thus,
to the extent that Plaintiffs did not raise the constitutional provisions at issue in Count Four at the
administrative level in their 2018 refund claim, the Court lacks jurisdiction to consider those
arguments here. Nevertheless, because Defendants do not contend that the Court lacks jurisdiction
as to the 2019 refund claim, the Court must stillconsider whether Plaintiffs state a claim in Count
Four.
Faith and Credit Clause provides that “Full Faith and Credit shall be given in each State to the
public Acts, Records, and judicial Proceedings of every other State.” U.S. Const. art. IV, § 1. The
Preamble to the U.S. Constitution states that the Constitution’s purpose is to “form a more perfect
union” and to “promote the general welfare.”
The Full Faith and Credit Clause does not apply to federal action. Instead, it “require[s]
the judgments of the courts of one State to be given the same faith and credit in another State as
they have by law or usage in the courts of the State rendering them.” Morris v. Jones, 329 U.S.
545, 547 (1947); see also Franchise Tax Bd. of Cal. v. Hyatt, 587 U.S. 230, 245 (“The Court’s
Full Faith and Credit Clause precedents . . . demand that state-court judgments be accorded full
effect in other States and preclude States from ‘adopt[ing] any policy of hostility to the public
Acts’ of other States.” (alteration in original) (citation omitted)); Zahl v. Warhaftig, 655 F. App’x
66, 77 (3d Cir. 2016) (noting that the Clause and implementing statute requires that federal courts
“give ‘full faith and credit’ to the judgments of state courts”). Plaintiffs challenge a provision of
a federal law and thus the Full Faith and Credit Clause does not apply.
Plaintiffs’ reliance on the Preamble to the Constitution is similarly misplaced. The
Preamble does not provide any substantive rights but rather “describes the goals and aspirations
behind the text of the Constitution.” Tinsley v. Methodist Hosp. of Ind., Inc., 70 F.3d 1275, 1275
(7th Cir. 1995) (citing Jacobson v. Commonwealth of Mass., 197 U.S. 11, 22 (1905)). It thus
cannot form the basis of any claim and Defendants’ motion to dismiss Count Four is granted.
E. Intergovernmental Tax Immunity (Count Five)
In Count Five, Plaintiffs assert that the SALT Deduction Cap conflicts with the Reciprocal
Immunity Doctrine, also known as Intergovernmental Tax Immunity. SAC ¶¶ 123–40. This
doctrine provides that the “States can never tax the United States directly,”whether the “levy falls
on the United States itself, or on an agency or instrumentality so closely connected to the
Government that the two cannot realistically be viewed as separate entities.” Baker, 485 U.S. at
523 (citations omitted). And the “rule with respect to state tax immunity [from direct federal taxes]
is essentially the same,” with some exceptions. Id.
Congress’s altering of the SALT Deduction does not violate this doctrine. Even if the Cap
was considered to be a tax, it merely changes the amount of income that may be collected by the
federal government from individualtaxpayersand thus is not a direct tax on the states themselves.
See id. at 526–27 (holding that a federal law removing a tax exemption from state-issued bonds
did not violate Intergovernmental Tax Immunity because the tax was “imposed on and collected
from bondholders,” and not from the states). The SALT Deduction Cap therefore does not violate
Intergovernmental Tax Immunity and Defendants’ motion to dismiss Count Five is granted.
F. Republican Guarantee Clause of Article IV (Count Six)
In Count Six,6Plaintiffs assert that the SALT Deduction Cap conflicts with the Republican
Guarantee Clause. SAC ¶¶ 141–46. This provision, which states that “[t]he United States shall
guarantee to every State in this Union a Republican Form of Government,” U.S. Const. art. IV, §
4, does not provide the basis for a justiciable claim. See Rucho v. Common Cause, 588 U.S. 684,
718 (2019) (noting that the Supreme Court has concluded “several times” that the Republican
Guarantee Clause “does not provide the basis for a justiciable claim”). Accordingly, Defendants’
motion to dismiss Count Sixis granted.
G. Sixteenth AmendmentClaims (Counts Eight and Nine)
6As with Count Four, see supra n.5, Defendants argue that the Court lacks jurisdiction to consider
Count Six with respect to Plaintiffs’ claims for a tax refund for 2018 (but not 2019) based on the
“variance doctrine.” Br. at 9–11. Again, because Defendants do not raise this argument as to the
2019 refund claim, the Court must still consider whether Plaintiffs state a claim in Count Six.
In Counts Eight and Nine, Plaintiffs assert that the SALT Deduction Cap violates the
Sixteenth Amendment, which provides that “[t]he Congress shall have power to lay and collect
taxes on incomes, from whatever source derived, without apportionment among the several States,
and without regard to any census or enumeration.” U.S. Const. amend. XVI.
i. The Sixteenth Amendment Does Not Require a SALT Deduction
Nothing in the text of the Sixteenth Amendment expressly requires a SALT deduction (or
any deduction at all), nor does it limit Congress’s authority to revoke or limit the SALT deduction
once enacted. Yellen, 15 F.4th at 580; see also Alpenglow Botanicals, 894 F.3d at 1202
(“Congress’s choice to limit or deny deductions for [certain business] expenses . . . does not violate
the Sixteenth Amendment.”). Nevertheless, Plaintiffs allege that the “meaning and intent” of the
Sixteenth Amendment shows that the SALT Deduction Cap is unconstitutional. SAC ¶ 165. They
add that the “States ratified the 16th Amendment with the representations and understanding that
it would not expand the taxing power of the federal government” and that “State tax revenues
could not be federally taxed.” Id. ¶¶ 163–64.
The Constitution originally provided that “[n]o . . . direct[] Tax shall be laid, unless in
Proportion to the Census.” U.S. Const. art. I, § 9, cl. 4. The Supreme Court had interpreted “direct”
taxes to include income taxes. See Bowers v. Kerbaugh-Empire Co., 271 U.S. 170, 174 (1926)
(citing Pollock, 158 U.S. at 618 (1895)). The Sixteenth Amendment then eliminated the
requirement that such “direct taxes” be subject to apportionment relative to the states’ populations.
Bowers v. Kerbaugh-Empire Co., 271 U.S. 170, 174 (1926) (citations omitted). Indeed, “it was
not the purpose or effect of that amendment to bring any new subject within the taxing power,” as
“Congress already had power to tax all incomes.” Id. Thus, Plaintiffs’ assertion that the states
ratified the amendment with the understanding that it would not expand federal taxing power is to
no avail as no such expansion occurred. Accordingly, the Sixteenth Amendment does not
implicitly require the SALT Deduction.
ii. History Does Not Show that the SALT Deduction is Constitutionally
Required
In the Sixteenth Amendment Counts and elsewhere, Plaintiffs assert that the history
surrounding the SALT Deduction shows that it is constitutionally required. See, e.g., SAC ¶ 157
(“In imposing an unprecedented $5,000 per person limitation on the deductibility of SALT
revenue, Congress has exceeded its powers under the 16th Amendment.”); id. ¶ 28 (“Congress has
never before limited the amount of the exemption from federal taxation and the deduction of SALT
revenues to a specific dollar cap of such taxes . . . .”). As an initial matter, “[l]egislative novelty
is not necessarily fatal; there is a first time for everything.” NFIB, 567 U.S. at 549. In Baker, for
example, the Supreme Court upheld a change to the tax code even where Congress had not altered
the relevant provision since enacting the first federal income tax statute. 485 U.S. at 523, 527.
More important, however, and contrary to Plaintiffs’ assertion, Congress has repeatedly
altered the availability and scope of the SALT Deduction. Yellen, 15 F.4th at 573 (“[A]mendments
to the Tax Code have over time also made the deduction more difficult or less attractive for
taxpayers to claim.”). For example, in 1964, Congress amended the SALT Deduction directly by
providing that only certain specific state and local taxes were deductible. Id. (citation omitted).
Congress made additional changes in 1986 by prohibiting certain high-income taxpayers from
claiming the SALT Deduction and then again in 1990 by reducing the amount of the SALT
Deduction available to taxpayers exceeding certain adjusted gross income thresholds. Id. at 573–
74 (citations omitted). Thus, rather than supporting Plaintiffs’ position, the history of the SALT
Deduction suggests that “Congress did not view its authority to limit the SALT deduction as
subject to any relevant constitutional constraints.”7 Yellen, 15 F.4th at 581–82.
iii. The SALT Deduction Cap Does Not Violate the Sixteenth Amendment or the
Uniformity ClauseBy Having a Non-Uniform Effect on the States
Count Nine also asserts that the SALT Deduction Cap exceeds the scope of the Sixteenth
Amendment because the Amendment “did not authorize unequal taxation of citizens based on the
state of residence.” SAC at 24. In addition to invoking the Sixteenth Amendment, this Count
appears to also rely on the Uniformity Clause of Article I, which provides that taxes “shall be
uniform throughout the United States.”8 U.S. Const. art. I, § 8, cl. 1.
Plaintiffs’ argument that a tax with non-uniform effects on taxpayers from different states
violates either constitutional provision lacks merit. All that the Constitution “requires is that the
law shall be uniform in the sense that by its provisions the rule of liability shall be alike in all parts
of the United States.” Florida v. Mellon, 273 U.S. 12, 17 (1927). It does not require “Congress
to devise a tax that falls equally or proportionatelyon each state.” United States v. Ptasynski, 462
U.S. 74, 82 (1983). Rather, a “tax is uniform when it operates with the same force and effect in
7 Beyond the legislative history, Courts have also upheld constitutional challenges to changes to
the SALT Deduction, including on Sixteenth Amendment grounds. See Campbell v. United States,
No. 00-4746, 2001 WL 1262934, at *3–4 (S.D.N.Y. Oct. 22, 2001) (finding that the 1980
amendment did not violate Article I, Section 8, the Tenth Amendment, or the Sixteenth
Amendments), aff’d, 45 F. App’x 50 (2d Cir. 2002); Okin v. C.I.R., 808 F.2d 1338, 1342 (9th Cir.
1987) (rejecting a due process challenge to the 1986 amendment to the SALT Deduction and
collecting cases that did the same).
8 Although Plaintiffs state that a claim under the Uniformity Clause “is not pled separately as a
cause of action herein,” Opp. at 47, they cite to case law concerning this Clause and invoke this
Clause to support their argument that the SALT Deduction Cap “creates uniformity problems.”
Id. at 49; see also id.at 51 (“Many clauses of the fabric of the Constitution are designed to ensure
that federal taxes . . . are applied equal to all states and their citizens.” (citing U.S. Const. art. I, §
8, cl. 1)). Accordingly, the Court will address this argument by reference to both the Sixteenth
Amendment and the Uniformity Clause.
every place where the subject of it is found.” Id. (quoting Head Money Cases, 112 U.S. 580, 594
(1884)). The SALT Deduction Cap meets this requirement,asacitizen of any state may claim the
deduction subject to the same Cap. See Campbell, 2001 WL 1262934, at *4 (finding that an earlier
amendment to the SALT Deduction applied equally to citizens of all states “as it limit[ed] itemized
deductions that all taxpayers above a specific adjusted gross income can take”). And the “outsized
effect of the SALT deduction cap on the [Plaintiffs] arises only because [they] previously
benefitted most from the SALT deduction, not because the cap applies to some States but not
others.” Yellen, 15 F.4th at 584. Thus, the SALT Deduction Cap does not unconstitutionally treat
taxpayers of the various states differently.
Finally, Plaintiffs’ reliance on statements by certain members of Congress and the
Executive branch suggesting that the SALT Deduction Cap was enacted to intentionally punish
certain states does not save their claim. See, e.g., SAC ¶¶ 45–53. Courts “generally presume that
government officials act in good faith.” Cnty. of Butler v. Governor of Pa., 8 F.4th 226, 230 (3d
Cir. 2021). And “‘cherry-picked’ statements” from individual legislators “cannot be deemed to
reflect the views of other legislators, much less of a majority of those who enacted the statute.”
OFC Comm Baseball v. Markell, 579 F.3d 293, 302 n.5 (3d Cir. 2009) (citation omitted). In any
event, a handful of quotes do not change the fact that the SALT Deduction Cap complies with the
Supreme Court’s requirements for tax uniformity. Therefore, Defendants’ motion to dismiss
Counts Eight and Nine is granted.
H. Declaratory Relief/Tax Refund (Count Ten)
In Count Ten, Plaintiffs request a judgment declaring the SALT Deduction Cap
unconstitutional. SAC ¶¶ 167–70. As no substantive claims remain in this action, the declaratory
judgment claim will be dismissed. See Bonilla v. City of Allentown, 359 F. Supp. 3d 281, 305
(E.D. Pa. 2019), as amended (Apr. 19, 2019).
