This cap was temporarily raised to $40,000 through 2029, which is a big deal for people living in high-tax states.
Knowing how to work within this limit, like timing your payments right, can actually save you some serious money.

What Is the SALT Deduction?

Although it might seem complex, the SALT deduction lets you subtract certain state and local taxes—like property, income, and sales taxes—from your federally taxable income. This tax benefit was established by the Revenue Act of 1913 and expanded in 1964. It allows you to reduce your taxable income on your federal tax return by deducting these state and local taxes.
The SALT deduction lets you reduce your federal taxable income by subtracting certain state and local taxes.
To claim the SALT deduction, you must itemize deductions on Schedule A rather than taking the standard deduction.
The Tax Cuts and Jobs Act introduced a tax cap that limits the SALT deduction to $10,000 per year. This change affects many taxpayers, especially those in high-tax states.
But here’s something recent: legislation has temporarily increased this cap to $40,000 for 2025-2029. Knowing this tax law helps you understand how property taxes, income taxes, and sales taxes work with your federal tax return. When you itemize deductions, it can potentially lower your tax liability.
Who Can Claim the SALT Deduction and How Does the Cap Work?

To claim the SALT deduction, you need to itemize your deductions on Schedule A instead of taking the standard deduction. Only taxpayers who itemize can benefit from the SALT deduction, which includes property taxes and either income taxes or sales taxes—but not both.
The deduction has a cap that limits how much you can claim each year. For 2025, the maximum deduction is $40,000 for most taxpayers, up from $10,000 in previous years. If you’re married and filing separately, your cap is $20,000.
Keep in mind, the SALT deduction applies at the federal level, reducing your taxable income by the amount of state and local taxes you paid, up to the cap. To maximize your deduction, you might consider prepaying property taxes or making early estimated tax payments before year-end, so they count for that tax year.
Understanding these rules helps you make the most of the SALT deduction within the allowed limits. It’s all about timing and knowing the limits to get the best benefit.
