State and Local Tax (SALT) deduction The State and Local Tax (SALT) deduction is a provision of United States federal income tax law that allows taxpayers to deduct certain state and local taxes from their federal taxable income. It has influenced fiscal relations among Congress, IRS, and state and local authorities such as the New York State Department of Taxation and Finance and California Franchise Tax Board, and it figures centrally in debates involving lawmakers from New York, California, Texas, Florida, and Illinois. The deduction has been shaped by landmark statutes and contested through litigation involving parties like the Supreme Court, Second Circuit, and various state supreme courts.
The deduction historically allowed individual taxpayers who itemize to deduct payments for qualifying taxes such as state and local income taxes, property taxes, and, in some periods, sales taxes, subject to federal rules codified in the Internal Revenue Code. Important actors in shaping rules include Congress committees like the House Ways and Means Committee and the Senate Finance Committee, as well as executive branch offices such as the Treasury Department. The provision affects stakeholders ranging from municipal governments including Chicago and Los Angeles to activist organizations like the Brookings Institution and Tax Foundation, and features in fiscal analyses by researchers at Harvard University, Stanford University, University of Chicago, and National Bureau of Economic Research.
Origins trace to federal income tax establishment under the Sixteenth Amendment and implementing legislation including the Revenue Act of 1913. Over the twentieth century, modifications arose through acts such as the Revenue Act of 1942, the Tax Reform Act of 1986, and regulatory guidance from the IRS. A major alteration occurred with the Tax Cuts and Jobs Act of 2017 enacted by the 115th Congress under the Trump administration, which imposed a $10,000 cap and excluded certain categories; legislative responses have come from members such as Nancy Pelosi, Mitch McConnell, Chuck Schumer, and Paul Ryan. State-level reactions involved governors like Andrew Cuomo, Gavin Newsom, and Larry Hogan, and state legislatures in New Jersey, Connecticut, and Massachusetts exploring workaround measures.
Eligibility typically requires taxpayers to itemize deductions on IRS forms such as Form 1040 schedules and to have paid qualifying taxes to jurisdictions including state revenue agencies like the New York City Department of Finance or county treasuries such as Los Angeles County Treasurer and Tax Collector. Calculation distinguishes among deductible taxes: state and local income taxes, real property taxes, and certain sales taxes, subject to guidance in the Internal Revenue Code and IRS publications. Taxpayers use worksheets and instructions influenced by rulings from bodies like the United States Tax Court and scholarly analyses from Columbia University and Yale University.
The $10,000 cap introduced by the Tax Cuts and Jobs Act of 2017 applies to the aggregate deduction for state and local income, sales, and property taxes for married couples filing jointly, with $5,000 for married filing separately, altering incentives for residents of high-tax jurisdictions including New York, New Jersey, California, and Connecticut. Prior to the cap, higher-income taxpayers and homeowners in cities like San Francisco and Boston often realized large federal tax benefits. Legislative proposals and state responses have included measures like charitable contribution workarounds advanced in legislatures of Maryland, Pennsylvania, and Rhode Island; some were subject to scrutiny under decisions such as Wayfair in the context of sales tax collection.
Empirical studies by institutions such as the National Bureau of Economic Research, Brookings Institution, Urban Institute, and universities including Princeton University and Massachusetts Institute of Technology examine the deduction’s incidence, showing benefits concentrated among higher-income taxpayers and homeowners in high-property-tax jurisdictions like Westchester County and Fairfax County. Analyses connect the deduction to migration patterns studied with data from the Census Bureau and to state fiscal choices reviewed by organizations like the Government Accountability Office. Debates compare efficiency effects discussed by economists such as Thomas Piketty and Emmanuel Saez against normative tax fairness arguments articulated by policymakers including Elizabeth Warren and Ronald Reagan in historical context.
Litigation over federal limits and state workarounds has reached federal courts including the Southern District of New York and appellate courts; notable actors include attorneys general from New York, California, New Jersey, and Connecticut. Cases have addressed whether certain state-created charitable or pass-through mechanisms violate federal tax law or the Constitution of the United States. The Supreme Court of the United States and circuit courts have considered questions about preemption, standing, and statutory interpretation, with briefs often filed by legal scholars from institutions like Georgetown University Law Center and Harvard Law School.
Policy proposals range from full repeal of the cap to replacement with credits or limitations targeted by income, advanced by lawmakers in the 116th Congress, 117th Congress, and think tanks such as the Tax Policy Center and American Enterprise Institute. Proposals align with political platforms of figures including Joe Biden, Donald Trump, Bernie Sanders, and bipartisan coalitions seeking regional relief for high-tax states. Reform options discussed include converting deductions into refundable tax credits, indexing caps to inflation, or restoring pre-2017 rules, with analyses by Congressional Budget Office and Joint Committee on Taxation estimating fiscal costs and distributional consequences.
