Quick Answer
The SALT deduction lets you deduct state and local taxes paid, but it's capped at $10,000 through 2025. This includes property taxes plus either income taxes OR sales taxes. For 2026, the cap expires and reverts to unlimited deductions, potentially saving high-tax state residents thousands.

Best for homeowners paying significant property and state income taxes
What exactly is the SALT deduction?
The State and Local Tax (SALT) deduction allows you to deduct taxes you paid to state and local governments from your federal taxable income. This includes property taxes on your home, plus either state income taxes OR state sales taxes (you choose whichever is higher).
The deduction is currently capped at $10,000 per year through 2025, but this cap expires for the 2026 tax year, reverting to unlimited deductions.
How the $10,000 cap works in practice
Let's say you're a homeowner in New Jersey earning $150,000. Here's what your SALT deduction might look like:
For 2026, this homeowner would save an additional $12,500 × 24% tax bracket = $3,000 in federal taxes compared to the capped years.
State income tax vs. sales tax election
You must choose between deducting state income taxes OR state sales taxes — not both. Most people benefit more from the income tax deduction, but if you:
Then the sales tax deduction might be better. The IRS provides tables showing average sales tax amounts by income and state, or you can track actual receipts.

Key factors that determine your benefit
What you should do
1. Track all SALT payments: Keep records of property tax bills, state estimated payments, and withholding
2. Consider timing: In December, you might prepay January property taxes to maximize deductions (check your state's rules)
3. Use our [return-scanner](return-scanner) to identify if you've missed any SALT deductions from prior years
4. Plan for 2026: With the cap expiring, high-SALT taxpayers should prepare for potential tax planning opportunities
Key takeaway: The SALT deduction is capped at $10,000 through 2025, but the cap expires in 2026. Homeowners in high-tax states could save $2,000-$5,000+ annually once the cap is lifted.
Key Takeaway: The SALT deduction covers state/local taxes up to $10,000 through 2025, but the cap expires in 2026, potentially saving high-tax state residents thousands annually.

For W-2 employees wondering if SALT affects them
Do I even need to worry about SALT?
If you take the standard deduction ($30,000 for married filing jointly in 2026, $15,000 for single filers), the SALT deduction cap doesn't directly affect you. You're not itemizing deductions, so you don't claim SALT anyway.
However, the SALT cap might be *why* you're taking the standard deduction instead of itemizing.
When SALT might matter for you
Even as a simple W-2 filer, consider itemizing if your total deductions exceed the standard deduction:
If you're a renter in a low-tax state earning $75,000, you're probably better off with the standard deduction. But if you bought a home or moved to a high-tax state, run the numbers.
The 2026 change could affect you
Once the SALT cap expires in 2026, some taxpayers who currently take the standard deduction might benefit from itemizing. If your property taxes are $8,000 and state taxes are $6,000, that's $14,000 in SALT alone — potentially making itemizing worthwhile.
Key takeaway: Most simple filers stick with the standard deduction, but the 2026 SALT cap expiration could make itemizing beneficial for homeowners in moderate-tax states.
Key Takeaway: Simple filers usually take the standard deduction, but removing the SALT cap in 2026 might make itemizing worthwhile for homeowners.

For couples in high-SALT states exploring filing strategies
The married filing separately SALT strategy
Here's a little-known strategy: the $10,000 SALT cap applies per tax return, not per person. So married couples filing separately each get a $10,000 SALT deduction, effectively doubling the cap to $20,000.
When this strategy works
Consider this example for a couple in California:
Filing jointly: SALT deduction = $10,000 (capped)
Filing separately: SALT deduction = $20,000 (each spouse claims $10,000)
This saves them $10,000 × 32% = $3,200 in federal taxes.
The downsides to consider
What you should do
Run the numbers both ways. This strategy typically works best for:
Remember: this strategy becomes less relevant in 2026 when the SALT cap expires entirely.
Key takeaway: Married filing separately can double your SALT deduction to $20,000, but only works in specific high-income, high-tax situations.
Key Takeaway: Married filing separately doubles the SALT cap to $20,000 total, potentially saving high-income couples in high-tax states $2,000-4,000 annually.
