The IRS $10,000 SALT tax deduction for 2025 remains a crucial consideration for taxpayers, especially those in high-tax states.

As tax laws evolve, consulting with a qualified tax professional can help ensure you’re optimizing your tax strategy effectively.
What Is the SALT Deduction and Why Does It Matter?
The State and Local Tax (SALT) deduction allows taxpayers to deduct certain taxes they pay to state and local governments. Before 2018, there was no limit on how much could be deducted. However, with the Tax Cuts and Jobs Act (TCJA) of 2017, a cap of $10,000 ($5,000 for married filing separately) was introduced, significantly reducing potential deductions for many taxpayers.
Who Benefits the Most from the SALT Deduction?
- Homeowners in high-tax states (California, New York, New Jersey, Illinois, Massachusetts, etc.)
- Individuals with high property taxes
- Taxpayers who itemize instead of taking the standard deduction
For example, if you pay $8,000 in state income taxes and $7,000 in property taxes, you can only deduct $10,000, leaving $5,000 non-deductible under the cap.

Strategies to Maximize Your SALT Deduction in 2025
Even with the $10,000 cap, there are smart ways to optimize your tax deductions:
1. Bunching Deductions
If your total SALT payments exceed the cap, consider prepaying property taxes or timing state tax payments to maximize your itemized deductions every other year.
2. Consider Alternative Tax Strategies
- Use donor-advised funds (DAFs) to increase itemized deductions.
- Maximize other deductible expenses, such as medical expenses exceeding 7.5% of your adjusted gross income (AGI).
3. Explore State-Level Workarounds
Some high-tax states have implemented Pass-Through Entity Tax (PTET) workarounds, allowing businesses to deduct state taxes at the entity level, bypassing the federal cap.
