SALT Deduction Explained Simply for 2026

The SALT deduction lets you subtract state and local taxes you paid during the year from your federal taxable income. SALT stands for State And Local Taxes, and it covers state income tax (or sales tax, but not both) plus property tax. For 2026, you can deduct up to $40,400 in total SALT on Schedule A when you itemize. The deduction only helps if your total itemized deductions exceed the standard deduction of $16,100(single) or $32,200 (married filing jointly).

What is the SALT deduction?

When you pay taxes to your state or local government, the federal government allows you to deduct some of those payments from your federal taxable income. This is the SALT deduction. It appears on Schedule A of your federal Form 1040 and is one of the most common reasons taxpayers choose to itemize deductions instead of taking the standard deduction.

The deduction reduces your taxable income, not your tax directly. If you deduct $40,400 in SALT and you are in the 24% federal tax bracket, the deduction saves you approximately $9,696 in federal tax. The higher your marginal tax bracket, the more each dollar of SALT deduction is worth.

What taxes count as SALT?

Three categories of taxes qualify:

1. State and local income taxes. The state income tax withheld from your paycheck, any estimated state tax payments you made, and any balance you paid when filing your state return. City and local income taxes (like New York City or Ohio municipal taxes) also count.
2. General sales taxes (as an alternative to income tax). You pick one or the other each year. If your state has no income tax (like Florida or Texas), you would choose sales tax.
3. Real property taxes. The property tax on your home, land, or other real property. This counts regardless of whether you choose income tax or sales tax above.

These three add together into one SALT total. That total is then compared to the cap.

Taxes that do not count: federal income tax, Social Security tax, Medicare tax, self-employment tax, foreign taxes, estate taxes, and fees like trash collection or sewer charges.

The 2026 cap: how much you can deduct

For 2026, the SALT deduction cap is:

If your total SALT exceeds the cap, you can only deduct the cap amount. The rest provides no federal tax benefit.

For taxpayers with MAGI above $505,000, the cap phases down by30% of each dollar above the threshold. Even at high incomes, the cap never drops below $10,000.

You must itemize to claim SALT

The SALT deduction is only available if you itemize deductions on Schedule A. You cannot claim it if you take the standard deduction. Every year, you choose whichever is larger:

• Standard deduction: $16,100 (single), $32,200 (MFJ), $24,150 (HoH). No paperwork needed.
• Itemized deductions: Add up SALT, mortgage interest, charitable contributions, and any other qualifying expenses. If the total exceeds the standard deduction, itemizing saves you more.

In 2026, about 90% of taxpayers take the standard deduction because the standard deduction amounts are high enough that itemizing does not produce a larger benefit. The SALT deduction primarily helps homeowners in high-tax states whose combined SALT and mortgage interest exceed the standard deduction threshold.

A simple example

This filer's $14,000 SALT is well below the $40,400 cap, so the full amount is deductible. Combined with mortgage interest and charitable donations, total itemized deductions reach $24,000, which exceeds the $16,100 standard deduction by $7,900. Itemizing produces a larger tax benefit.

This renter's itemized deductions total only $3,000. The $16,100 standard deduction is far larger, making the SALT deduction irrelevant for this taxpayer.

Who benefits most from SALT?

The SALT deduction provides the greatest benefit to taxpayers who:

• Live in high-income-tax states (California, New York, New Jersey, Connecticut, Massachusetts, Oregon, Minnesota)
• Own property with high property tax assessments
• Have MAGI below $505,000 so the full cap is available
• Have enough other itemized deductions (mortgage interest, charitable contributions) that total itemized deductions exceed the standard deduction

Homeowners in the New York City metro area, northern New Jersey, and coastal California are among the most likely to claim the maximum SALT deduction because they face high state income tax rates and high property tax assessments simultaneously.

Common mistakes to avoid

• Claiming both income tax and sales tax. You must pick one. Most people in income-tax states should choose income tax.
• Including federal taxes. Federal income tax, Social Security, and Medicare are not SALT.
• Itemizing when the standard deduction is larger. Claiming SALT only makes sense as part of itemizing. If your total itemized deductions are below the standard deduction, you lose money by itemizing.
• Forgetting estimated payments. If you made estimated state tax payments during the year, those count as SALT in the year paid.
• Missing local income taxes. City and county income taxes (common in New York City, Philadelphia, and Ohio municipalities) are deductible SALT that taxpayers sometimes overlook.
