What the salt cap means in plain English

The One Big Beautiful Bill Act temporarily raised the limit on the state and local tax (SALT) itemized deduction from $10,000 to $40,000 for 2025. The limit is indexed, so for tax year 2026 it is $40,400 ($20,200 for married filing separately). The higher limit applies for tax years 2025 through 2029, then is scheduled to revert to $10,000 in 2030 unless extended.

Unlike the Schedule 1-A deductions, the SALT deduction is an itemized deduction claimed on Schedule A — you only benefit if your total itemized deductions exceed the standard deduction. SALT includes state and local income (or sales) taxes plus property taxes.

For high earners the limit phases down. For 2026, once modified adjusted gross income exceeds $505,000 ($252,500 for married filing separately) the $40,400 limit is reduced by 30% of the excess income, but it never falls below the old $10,000 floor ($5,000 for married filing separately). Both the limit and the threshold are indexed each year through 2029.

PTET & SALT Workarounds
Business owners can sidestep the SALT cap by paying state tax at the entity level — here's how PTET works.

Who qualifies

  • You itemize deductions on Schedule A (your itemized total beats the standard deduction).
  • You paid state and local income or sales taxes plus property taxes during the year.
  • Married-filing-separately taxpayers get half the limit ($20,200 for 2026).
  • Your MAGI determines whether the $40,400 limit is reduced toward the $10,000 floor ($5,000 if married filing separately).

Common mistakes to avoid

  • Expecting the higher cap to help even though you take the standard deduction — SALT only matters if you itemize.
  • Forgetting the limit is per return, so married-filing-separately filers are limited to $20,200 each for 2026.
  • Assuming the higher limit is permanent — it is scheduled to revert to $10,000 in 2030.
  • Overlooking the high-income phase-down, which for 2026 reduces the limit above $505,000 MAGI ($252,500 if married filing separately).

SALT Cap FAQs

What is the SALT deduction cap for 2026?

For 2026 the SALT (state and local tax) itemized deduction is limited to $40,400 ($20,200 for married filing separately) — up from $10,000 under prior law. The higher limit applies for tax years 2025 through 2029 before reverting to $10,000 in 2030. It phases down for taxpayers with modified adjusted gross income above $505,000 ($252,500 for married filing separately). Verify current figures with IRS instructions.

Do I have to itemize to use the higher SALT cap?

Yes. SALT is an itemized deduction claimed on Schedule A, so you only benefit if your total itemized deductions — including SALT, mortgage interest, and charitable gifts — exceed your standard deduction. If you take the standard deduction, the SALT cap doesn't affect you.

How does the high-income SALT phase-down work?

For 2026, once modified adjusted gross income exceeds $505,000, the $40,400 limit is reduced by 30% of the income above that threshold, but it never drops below the $10,000 floor. For example, $605,000 MAGI is $100,000 over the threshold; 30% of $100,000 is $30,000, reducing the limit from $40,400 to $10,400. The limit reaches the $10,000 floor at about $606,334 of MAGI. Married filing separately halves the limit, the threshold, and the floor to $20,200, $252,500 and $5,000.

What taxes count toward the SALT deduction?

SALT includes state and local income taxes (or, alternatively, state and local general sales taxes) plus state and local property taxes. You add these together and deduct the total up to the cap. Federal taxes and most fees do not count.
