The State and Local Tax (SALT) deduction has been one of the most talked-about tax topics since the $10,000 cap was introduced under the Tax Cuts and Jobs Act of 2017 (TCJA). For many homeowners and higher-income earners, this cap significantly reduced the ability to deduct property taxes, state income taxes, and certain local taxes.
Beginning in the 2025 tax year, however, the rules are changing again, bringing a mix of increased opportunity and phased-in limits. Here’s what taxpayers need to know about the newly expanded SALT deduction.
1. The SALT Deduction Cap Increases to $40,000 for 2025
For the 2025 tax year, the deduction cap for state and local taxes increases dramatically:
- New cap: $40,000 for most individual taxpayers
- Married filing separately: $20,000 cap
This represents a significant boost from the previous $10,000 limit and may offer meaningful tax relief for Floridians who own properties elsewhere or have multistate income.
While Florida has no state income tax, many residents pay substantial property taxes or own second homes in states with higher tax burdens, making this increase particularly valuable.
2. Income-Based Phase-Down for Higher Earners
Although the new $40,000 cap is generous, it does not apply evenly to every taxpayer. The expanded deduction begins to phase down for higher-income individuals starting at:
- $500,000 in modified adjusted gross income (MAGI) for single filers
- $250,000 MAGI for married filing separately
The cap is reduced by 30% of the amount by which a taxpayer’s MAGI exceeds the threshold, but never below $10,000 (or $5,000 for married filing separately).
What this means practically:
- If your income is below $500,000 (or $250,000 MFS), you may receive the full $40,000 deduction.
- If your income is above these thresholds, your deduction could be reduced but not lower than the original $10,000 limit.
For high-income households, planning ahead will be essential.
3. Gradual Annual Increases From 2026-2029
From January 1, 2026 through December 31, 2029:
- The SALT cap and
- The income thresholds
will increase by 1% each year.
This slow upward adjustment helps maintain the deduction’s value as income and property taxes rise over time. It also means taxpayers should evaluate their SALT exposure annually to ensure they’re maximizing available deductions.
4. The Cap Reverts in 2030
Beginning in 2030, the SALT deduction cap reverts back to:
- $10,000 for most individuals
- $5,000 for married filing separately
This makes the next several years a window of opportunity for strategic tax planning.
5. What This Means for You
Even though Florida has no state income tax, the expanded SALT deduction can still offer substantial benefits for:
- Homeowners with significant property taxes
- Individuals with income or real estate interests in other states
- Retirees who split residency between Florida and higher-tax states
- Business owners with multistate operations
- Investors with properties nationwide
Understanding where you fall within the new income thresholds is crucial for maximizing the deduction.
