The year 2025 brings good news for homeowners in high-tax states as the state and local tax (SALT) deduction cap has quadrupled to $40,000. This significant increase from the previous limit of $10,000 is a game-changer for high-income taxpayers this year.
The SALT deduction allows you to deduct various non-federal taxes you have paid, up to $40,000 for the 2025 tax year (taxes due on April 15, 2026). However, it’s important to note that you can only claim the SALT deduction if you choose to itemize your deductions. If you opt for the standard deduction, this tax break will not be available to you.
The amount you can benefit from the SALT deduction depends on factors such as your income, state and local tax burden, and other deductions you claim on your tax return. The SALT deduction covers a range of taxes including state and local income taxes, property taxes, local taxes, and even sales taxes in states without income tax.
The SALT cap is set to increase by 1% annually, along with the income phase-out threshold. If no action is taken by lawmakers, the limit will revert back to $10,000 in 2030.
The SALT deduction is a valuable tax break, especially for middle- to high-income households in states with high income taxes like California, New York, and Connecticut. Families in the $400,000 to $500,000 income range are likely to see the largest reductions in their federal tax bills.
To prevent the deduction from benefiting only the ultra-wealthy, the OBBB introduced a phase-out for high earners starting in 2026. This means that once your income exceeds $500,000 ($250,500 if married filing separately), the deduction starts to decrease.
Claiming the state and local tax deduction requires careful documentation of property taxes, state income or sales taxes, and personal property taxes. For those living in states without income tax, the IRS Sales Tax Deduction Calculator can help estimate the standard sales tax deduction.
Staying organized throughout the year with your tax-related documents is key to maximizing the benefits of the SALT deduction. If your tax situation is complex, seeking assistance from a tax preparer can help you navigate the process efficiently.
The $40,000 cap for the SALT deduction applies to single filers and married couples filing jointly for the 2025 tax year. For married couples filing separately, the cap is $20,000 per person.
The expanded $40,000 cap is set to remain in place through the 2029 tax year with annual inflation adjustments. However, if Congress does not take action, the cap will revert back to $10,000 in 2030.
