For 2026 the deduction for state and local taxes (SALT) is capped at $40,400 per return, or $20,200 if you are married filing separately, up from $40,000 in 2025. The cap shrinks once modified AGI passes $505,000: it drops by 30% of the amount over, but not below $10,000. You only get the deduction if you itemize.
What counts toward the cap
The cap covers the state and local taxes you deduct on Schedule A:
- state and local income taxes, including amounts withheld from your pay and estimated payments, or general sales taxes instead;
- real estate taxes on your home and other property you own personally (see the property tax calculator);
- personal property taxes charged every year and based only on value, such as the value-based part of some car or boat taxes.
How the cap shrinks with income
Above the $505,000 threshold, each $1,000 of modified AGI cuts the cap by $300. The cap reaches the $10,000 floor at $606,333. Modified AGI is your AGI with a few adjustments listed in the Schedule A instructions.
| Modified AGI | SALT cap |
|---|---|
| $505,000 | $40,400 |
| $531,000 | $32,600 |
| $556,000 | $25,100 |
| $581,000 | $17,600 |
| $607,000 | $10,000 |
Single, head of household and married filing jointly. Married filing separately: half the cap, threshold and floor.
Itemize or take the standard deduction?
The SALT deduction is one of the itemized deductions, so it only matters if your itemized total beats the standard deduction: $16,100 for single filers, $24,150 for heads of household and $32,200 for married couples filing jointly in 2026. The income tax calculator uses the standard deduction, so subtract the difference yourself if you itemize. If you live in a state without income tax, the state map shows which ones, and deducting sales tax may help. If you live in a high-tax state, see which ones are ranked highest for income tax.
What happens after 2029
The law that raised the cap (Public Law 119-21) lets the cap and the income threshold rise a little each year through 2029. Starting in 2030 the phase-down ends and the cap returns to $10,000 for everyone, unless Congress changes it again.

Frequently asked questions
What is the SALT cap for 2026?
$40,400 for single, head of household and married filing jointly returns, and $20,200 for married filing separately. It is reduced for modified AGI over $505,000 ($252,500 separately).
Is the SALT cap per person or per return?
Per return. A married couple filing jointly gets one $40,400 cap, the same as a single filer. Filing separately gives each spouse $20,200.
Do I get the SALT deduction if I take the standard deduction?
No. State and local taxes are an itemized deduction on Schedule A. You only benefit if all your itemized deductions add up to more than your standard deduction ($16,100 single, $32,200 married filing jointly for 2026).
Can I deduct both state income tax and sales tax?
No. You choose one: state and local income taxes or general sales taxes. Property taxes are added either way.
What happens to the SALT cap after 2029?
Under current law the phase-down ends and the cap goes back to $10,000 starting in 2030.
