SALT Deduction Cap Raised to $40,000 Under OBBBA 2026
The One Big Beautiful Bill Act (OBBBA) raises the State and Local Tax (SALT) deduction cap from $10,000 to $40,000 for married filing jointly ($20,000 for single filers) for tax years 2025 and 2026. This is a landmark change for taxpayers in high-tax states who have been severely limited since the TCJA imposed the $10,000 cap in 2018.
Who Benefits Most?
Taxpayers in high-tax states with significant state income tax and property tax bills will see the largest benefit:
- California — Top state income tax rate: 13.3%
- New York — Top state income tax rate: 10.9%
- New Jersey — Top state income tax rate: 10.75%
- Illinois — Flat state income tax: 4.95%
- Massachusetts — Flat state income tax: 5%
Example Savings
California couple paying $35,000 state income tax + $8,000 property tax = $43,000 total SALT:
- Under old cap: $10,000 deductible → $3,700 tax savings at 37%
- Under OBBBA: $40,000 deductible → $14,800 tax savings at 37%
- Additional savings: $11,100 per year
SALT Cap Planning Strategies
- Bunching SALT payments: Prepay Q4 state estimated taxes in December to maximize the deduction in the current year
- Pass-Through Entity (PTE) tax elections: Many states allow S-corps and partnerships to pay state tax at the entity level, bypassing the SALT cap entirely — this strategy remains valuable even with the higher cap
- Property tax prepayment: Prepay next year's property taxes before December 31 to maximize current-year deductions
Important Limitations
- The SALT deduction is only available to taxpayers who itemize (Schedule A)
- The Alternative Minimum Tax (AMT) does not allow SALT deductions — high-income taxpayers should model AMT exposure
- The $40,000 cap applies to the combined total of state income taxes, local income taxes, and property taxes
