Obbba Salt Deduction 40000

The OBBBA raises the SALT deduction cap to $40,000 for married filing jointly. Learn who benefits most, how to maximize your SALT deduction, and state-level planning strategies.

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
