For tax year 2026, the federal SALT deduction is capped at $40,400 for single, head-of-household and married-filing-jointly filers. Married taxpayers filing separately have a $20,200 ceiling. The higher limit does not apply automatically to every return.
A taxpayer must itemize deductions on Schedule A to claim it. That means comparing eligible itemized expenses with the standard deduction for the applicable filing status. The SALT deduction limit may rise, but it only affects a return when itemizing is worthwhile.
The cap also narrows as income climbs. The phase-down begins when 2026 modified adjusted gross income, or MAGI, exceeds $505,000 for most filing statuses, and $252,500 for married taxpayers filing separately.

A 30% reduction applies to income above the relevant threshold, subject to a floor. Married-separate filers have a lower floor than other filers.
The cap starts shrinking above $505,000 in MAGI
For filers other than married taxpayers filing separately, the calculation subtracts 30% of MAGI above $505,000 from the $40,400 maximum. The reduction cannot push the cap below $10,000. Separate filers use their own threshold and a $5,000 minimum.
| 2026 MAGI example | Available cap |
|---|---|
| $505,000 or less | $40,400 |
| $525,000 | $34,400 |
| $600,000 | $10,000 |
At $525,000 of MAGI, the phase-down removes $6,000 from the maximum. At $600,000, the calculation would put the cap below its minimum, so the floor applies instead.
Only paid personal taxes qualify for the combined cap
Eligible amounts include state and local income taxes or general sales taxes, but not both. Real-estate property taxes and personal-property taxes can also count. Property and income taxes draw on one shared limit.
The deduction cannot exceed qualifying SALT actually paid. A tax bill alone is not enough if payment has not been made in the relevant tax year. Personal itemized deductions also should not be confused with tax expenses properly claimed by a business or rental activity.
Itemizing and income planning can change the result
Start by adding deductible SALT to mortgage interest, charitable contributions and other allowable itemized deductions. If that combined total does not exceed the standard deduction for the filing status, the higher SALT ceiling will not make itemizing beneficial on its own.
Income planning may reduce or limit the phase-down for taxpayers who qualify. Traditional 401(k) contributions and HSA contributions can affect income, as can the timing of bonuses, capital gains, Roth conversions and other income. The result depends on a taxpayer’s circumstances and eligibility.
Charitable gifts offer another way to make itemizing worthwhile in a particular year. Someone whose deductions sit near the standard-deduction threshold may concentrate several years of donations into one year, sometimes using a donor-advised fund. That can increase itemized deductions for that year rather than spreading gifts across multiple years.
The tax categories also call for a deliberate choice. Taxpayers can claim state and local income taxes or general sales taxes, not both. People living in states without an income tax may find it useful to document eligible sales-tax expenses instead.
Payment dates and assessments affect the amount claimed
Property taxes generally count when paid to the taxing authority. With an escrow account, the relevant payment is generally the mortgage servicer’s remittance, not the earlier deposit into escrow.
A property owner can also review a local assessment for errors. Reducing an excessive assessment may lower the tax bill and leave more room under the shared cap for state income tax or other qualifying taxes.
A business election may keep some state tax outside the cap
Owners of eligible partnerships, S corporations and other pass-through businesses may be able to use a state pass-through entity tax election, or PTET. Under such a regime, the entity pays state income tax, which is generally deducted at the business level rather than counted against the owner’s individual SALT cap.
Election requirements and deadlines vary by state. Business and rental property taxes may also follow different rules when they qualify as business or rental expenses; they should not automatically be treated as personal itemized deductions.
The higher ceiling is scheduled to end after 2029
The increased cap is scheduled to rise by 1% annually through 2029, then return to $10,000 in 2030 absent further legislation. The phase-down and the itemizing requirement continue to shape how much of the higher limit an individual can use.
