Homeowners who itemize their federal tax return got real relief from a provision buried in the tax-and-spending law President Trump signed on July 4, 2025. The cap on how much state and local tax a filer can deduct — property taxes, state income tax, or state sales tax — jumped from $10,000 to $40,000, a limit that had squeezed itemizers in high-tax states since 2018. The increase is temporary, income-limited at the top, and only helps those who itemize in the first place, but for the households it reaches, it is one of the larger changes in the law.
What the SALT cap was, and what the new law changed
The 2017 Tax Cuts and Jobs Act first capped the state and local tax, or SALT, deduction at $10,000 per household starting in 2018, a limit that hit hardest in states with high property taxes or state income taxes. The enrolled text of H.R. 1, the One Big Beautiful Bill Act, raises that cap to $40,000 — $20,000 for married couples filing separately — effective for the 2025 tax year, according to the Bipartisan Policy Center’s explainer of the provision. The cap itself rises by 1 percent each year through 2029, so the effective limit is somewhat higher than $40,000 for the 2026 tax year and beyond.

How the $40,000 cap phases down for higher earners
The higher cap is not available in full to every filer who itemizes. It begins phasing down at a 30 percent rate once modified adjusted gross income exceeds $500,000 for most filers, or $250,000 for married couples filing separately, with that threshold also rising 1 percent annually through 2029. As income climbs above the threshold, the deduction shrinks back down, eventually bottoming out at the old $10,000 floor for the highest earners — meaning the biggest beneficiaries of the increase sit in the upper-middle range of the income distribution, not at the very top.
The rule is temporary — it snaps back in 2030
Unlike some provisions of the law that were made permanent, the higher SALT cap is written to expire. Beginning with the 2030 tax year, the cap reverts to the original $10,000 limit, with no income-based phase-down attached at that point. Anyone budgeting around the higher deduction for the long term should treat 2025 through 2029 as the window in which it applies, not as a permanent fixture of the tax code.
Why this matters most for retirees with high property-tax bills
For a retiree who owns a home outright or nearly so in a high-tax state, property taxes alone can approach or exceed the old $10,000 cap, especially in parts of California, Connecticut, Maryland, New Jersey, and New York, where a large share of filers have historically claimed SALT deductions. A retiree in one of those states who also pays state income tax on pension income, retirement account withdrawals, or investment income may now be able to deduct the full combination up to $40,000, compared with being capped at $10,000 total under the prior rule. That said, the deduction only reduces a bill for someone who itemizes on IRS Schedule A rather than taking the standard deduction, so a retiree whose total itemized deductions still fall short of the standard deduction amount sees no benefit from the higher cap at all.
A simple illustration of the difference
To see the size of the change, consider a retired couple with a $12,000 annual property tax bill and another $9,000 in state income tax withheld from pension and retirement-account income — a combined $21,000 in state and local taxes. Under the old $10,000 cap, that household could only deduct $10,000 of the $21,000 actually paid, losing the deductibility of the remaining $11,000. Under the new $40,000 cap, the same household can deduct the full $21,000, provided their total itemized deductions still exceed the standard deduction for a married couple. The gap between what was paid and what could be deducted has effectively closed for households whose combined state and local tax bill lands anywhere under the new ceiling — the exact scenario common among retirees who have paid off a home in a high-tax jurisdiction but still owe state tax on retirement income.
Who gets no benefit at all from the higher cap
Two groups see little or no change from this provision. Retirees who take the standard deduction because their total itemized expenses, even with the larger SALT allowance, do not exceed it gain nothing from the higher cap. And retirees whose income sits well above the $500,000 phase-down threshold see the deduction shrink back toward the old $10,000 limit regardless of how much they actually paid in state and local taxes. The provision is aimed squarely at the middle of the itemizing population — homeowners with meaningful but not extreme incomes in high-tax states — rather than at either end of the income spectrum.
