SALT (State and Local Tax)

What Is SALT (State and Local Tax)?

The acronym SALT stands for state and local tax and generally is associated with the federal income tax deduction for state and local taxes available to taxpayers who itemize their deductions. In 2017, a $10,000 ceiling on the previously unlimited SALT deduction was enacted and made applicable for tax years beginning in 2018 and continuing through 2025.

The limitation on the deduction has prompted continuing political debate with high-income individuals and officials in states with high taxes, leading to intense opposition.  

Key Takeaways

  • SALT refers to the state and local taxes associated with a federal income tax deduction for taxpayers that itemize their deductions.
  • A $10,000 ceiling on the previously unlimited SALT deductions was enacted and made applicable for taxpayers between 2018 and 2025.
  • Individual taxpayers who itemize their personal deductions can deduct up to $10,000 of their aggregated state and local taxes per return annually ($5,000 for married people filing separately).
  • The Joint Committee on Taxation estimates large revenue decreases for the government as a result of limitations on SALT deductions.

Understanding SALT

Individual taxpayers who itemize their personal deductions can deduct up to $10,000 of their aggregated state and local taxes per return annually ($5,000 for married people filing separately). The limitation does not apply to taxes paid or accrued in carrying on a trade or business or incurred as expenses in an income-producing activity.

Deductible taxes include state, local, and foreign taxes on income, war profits, and excess profits; and state and local (but not foreign) taxes on personal property and real property, including amounts paid by tenant-stockholders to cooperative housing corporations with respect to such corporations’ real estate taxes.

Taxpayers can elect to deduct state and local general sales taxes in lieu of claiming a deduction of income taxes. Deductible state and local sales taxes include taxes on retail sales, similar “compensating use” taxes for the use, storage, or consumption of items, and taxes on motor vehicles.

Taxes imposed on certain income distributions related to generation-skipping transfers by trusts and estates are also deductible if the distribution is included in the taxpayer's income.

Federal Revenue Impact

Opponents of the SALT deduction limitation face a significant issue: the impact of the limit on federal revenue. The $10,000 limit on SALT deductions has a significant, measurable revenue impact affecting the federal budget.

The Joint Committee on Taxation estimates that an increase in the limitation on deductions for SALT for married individuals for 2019 and a termination of deductions in 2020 and 2021 would reduce revenues by a total of $184.5 billion between 2019 and 2024.

Efforts to Alleviate or Eliminate SALT Ceiling

Shortly after the ceiling on the SALT tax deduction passed, a change that hit taxpayers in states with high income and property taxes particularly hard, efforts began to restore the previously unlimited deduction.

Recharacterization as Charitable Contribution

States reacted quickly to the ceiling on SALT deductions and undertook various steps to reduce their federal tax cost for their citizens and the negative political environment that it created for state and local taxation. Initial efforts by several states to allow their residents to contribute to a state charitable fund instead of paying income taxes were thwarted by final regulations issued by the U.S. Treasury Department to countermand this approach.

Litigation

Connecticut, Maryland, New Jersey, and New York filed a lawsuit challenging the SALT ceiling as unconstitutional. The case was dismissed by a federal district court, and in 2021, the U.S. Supreme Court also found against the states.  

Special Relief for Pass-Throughs

Owners of pass-through entities (also known as flow-through entities)—principally partnerships and S corporations—received indirect relief from the SALT ceiling in Internal Revenue Service (IRS) Notice 2020-75, issued on Nov. 9, 2020.

The notice stated that forthcoming regulations would allow partnerships and S corporations to claim SALT deductions at the entity level without applying the SALT ceiling. This will allow income to pass through to partners and shareholders on an after-tax basis, without having to take into account their share of the SALT deductions previously claimed by the entity, in determining the SALT cap for their tax returns.

Legislative Repeal

Repeal would be the one clearly effective method for eliminating the SALT cap, but its prospects are uncertain. Although some members of both parties favor repeal, most proponents are Democrats representing states with higher state and local taxes. Republicans—who more commonly represent lower-tax states—generally do not support repeal.

In November 2019, the U.S. House of Representatives passed a partial repeal of the SALT cap by a vote of 218–206, with five Republicans voting for the bill and 16 Democrats—mainly progressives who considered it inadequate—voting against it. The bill would have raised the cap to $20,000 for joint returns for 2019 and eliminated it for 2020 and 2021 for taxpayers with incomes below $100 million. It would have left the $10,000 cap in place for 2023 through 2025.

In early 2021, bills to eliminate the SALT cap were introduced in both houses of Congress. In the House of Representatives, proposed legislation already had more than 106 co-sponsors before March. In the Senate, Majority Leader Sen. Charles Schumer, D-N.Y., introduced a total-repeal bill, while Sen. Susan Collins, R-Maine, introduced legislation to increase the limit to $20,000 for joint returns.  

Because the present law about the ceiling on SALT deductions expires after Dec. 31, 2025, the SALT cap will disappear in 2026 unless it is extended by legislation in the interim.

What State and Local Taxes Can Be Deducted?

The SALT deductions allow for deductions on income taxes and property taxes, or sales tax in lieu of income tax. Certain taxes, such as those on gasoline, car inspections, and property improvements cannot be deducted.

How Much Can I Deduct for State and Local Taxes?

The total amount that a taxpayer can deduct for state and local taxes if they itemize their deductions is $10,000.

What Is the SALT Cap Workaround?

The SALT cap workaround was enacted in 2021 in California and allows for business taxed as S corporations or partnerships to choose to pay a 9.3% state income tax. The owners of the businesses can claim a credit on their income tax equal to the amount the business paid. Other states have adopted workarounds.
