More than a year after Republicans passed President Donald Trump's tax package, the state and local tax deduction is temporarily more generous. The cap jumped from $10,000 in 2024 to $40,000 for 2025, then to $40,400 for 2026. It is scheduled to climb by 1% each year through 2029, then drop back to $10,000 in 2030.
SALT stands for state and local taxes. You can count property taxes and then choose either state and local income taxes or sales taxes for the same year, but not both. Only itemizers can claim it. Before the 2017 overhaul, there was no ceiling, and the 2018 cap stung many taxpayers in higher tax states.
Taxpayers pick between the standard deduction and their total itemized deductions. In 2026, individuals get a standard deduction of $16,100, while married couples filing jointly receive $32,200. Itemized write-offs can include SALT, charitable donations, medical expenses and more. In the 2023 tax year, the IRS reports that about nine in ten filers opted for the standard deduction.
The bigger cap tends to favor higher earners who itemize. According to Garrett Watson, the Tax Foundation's vice president of federal tax policy, who spoke to CNBC, it generally aids "upper-middle to upper-income earners" because of income based phase-outs. The expanded cap also created what pros call a SALT torpedo. As certified financial planner Joon Um, managing owner of Secure Tax and Accounting in Hayward, California, put it, "The higher cap creates more opportunity, but higher-income taxpayers can lose the benefit as income rises."
Here is how that plays out in 2026: once modified adjusted gross income rises above $505,000, the full $40,400 deduction starts to phase down, and by roughly $606,333 of income and higher, the SALT break is back at $10,000. Between those amounts, you effectively give up 30% of each dollar of SALT benefit, which pushes up the marginal bite. Precise income planning matters for anyone in that range.

The IRS has not yet published specifics on SALT claims for 2025. Still, some numbers showed filers in high tax states like California and New Jersey received larger refunds during the 2026 filing season. Heather Long - Navy Federal Credit Union's chief economist - said that pattern could indicate some taxpayers benefited from the higher SALT cap.
Because only itemizers benefit, many are stacking deductions into one year to clear the standard deduction. Juan Hernandez-Ariano, a certified financial planner and the founder of WealthCreate in Houston, noted that a household that typically misses itemizing could tip the balance by remitting this year's property taxes ahead of schedule and making an additional payment by Dec. 31 toward next year's bill. If your mortgage servicer escrows property taxes, though, you may have less wiggle room. Also, you must have received the property tax assessment before prepaying, and assessment schedules vary by location.
If you have state quarterly estimated taxes for self-employment, a small business, or investment income, you could make the final 2026 state payments by Dec. 31 to load more deductions into the year. The federal fourth quarter estimated tax due date is Jan. 15, 2027, and state deadlines may be different.
For clients hovering near the phase-out, Um said he is "looking closely" at income creators like Roth conversions, capital gains, or year end bonuses, since those can push earnings into the band where the SALT benefit erodes.
If you usually itemize or hover close to the threshold, the timing of property and state tax payments in 2026 could move the needle for your tax bill. The sweet spot is getting enough deductions in the year to beat the standard deduction while staying mindful of the $505,000 to $606,333 income window where the SALT break fades and your effective rate can jump.
