Understanding the SALT Deduction Cap
The State and Local Tax (SALT) deduction cap, introduced under the Tax Cuts and Jobs Act (TCJA) of 2017, limits individuals to a $10,000 deduction for state and local income, sales, and property taxes on their federal tax return. This cap disproportionately impacted taxpayers in high-tax states such as New York, California, New Jersey, and Illinois.
However, with the TCJA provisions set to expire after 2025, discussions around adjusting or removing the SALT cap have gained traction in Congress. Lawmakers on both sides of the aisle—especially from high-tax states—are advocating for relief or a repeal, potentially making the SALT deduction fully or partially deductible once again for many filers.
Key Developments:
- House Proposals in 2023 and 2024 suggested increasing the SALT cap for married filers or eliminating it entirely for households under certain income thresholds.
- The Biden Administration’s Budget Proposal included language supporting targeted SALT cap relief for middle-income taxpayers.
- If Congress fails to act, the $10,000 SALT cap will sunset after 2025, restoring unlimited deductions for state and local taxes unless a new law is passed.

Implications for Tax Planning
A change to the SALT cap will have broad implications for:
- Itemizing vs. Standard Deduction strategies
- Income and property tax planning
- AMT exposure for high-income filers
- Real estate tax projections and planning
Tax professionals should prepare now to revise multi-year strategies for impacted clients.
