Quick Answer
The 2026 SALT deduction cap increased to $20,000 for married filing jointly (up from $10,000) and $10,000 for single filers (unchanged). This doubles the deduction limit for married couples, potentially saving high-tax state residents up to $2,200 annually in federal taxes.

Taxpayers in moderate to high-tax states who itemize deductions
How the SALT deduction limits changed for 2026
The Tax Cuts and Jobs Act originally capped the state and local tax (SALT) deduction at $10,000 starting in 2018. For 2026, Congress made a significant adjustment through the One Big Beautiful Bill Act, raising the cap to $20,000 for married filing jointly while keeping it at $10,000 for single filers.
This change primarily benefits married couples in high-tax states like California, New York, New Jersey, and Connecticut, where property taxes alone can exceed $15,000 annually.
Example: California couple's tax savings
Consider Maria and David, a married couple in San Jose earning $180,000 combined. Their annual SALT payments include:
Under the old $10,000 cap, they could only deduct $10,000, losing $16,500 in potential deductions. Under the new $20,000 cap, they can deduct $20,000, losing only $6,500.

High-income taxpayers in the 32%+ tax brackets who maximize itemized deductions
Strategic implications for high earners
For taxpayers in the 32%, 35%, or 37% tax brackets, the doubled SALT cap for married filers creates significant planning opportunities. The maximum additional federal tax savings jumps to $3,700 for those in the top bracket.
Advanced planning considerations
Timing state tax payments: With the higher cap, you may benefit from prepaying estimated state taxes in December rather than January, especially if you're near the $20,000 threshold.
Property tax timing: Consider timing property tax payments to maximize the deduction in years when you're in higher brackets or have other large itemized deductions.
Multi-state complications: If you have income in multiple states, the aggregate of all state and local taxes counts toward the cap. High earners with complex multi-state situations should model different scenarios.
AMT interaction remains critical
Remember that SALT deductions are completely disallowed for Alternative Minimum Tax (AMT) purposes. High earners subject to AMT (roughly $1.2 million+ for MFJ in 2026) won't benefit from any SALT deduction, regardless of the cap increase.
Key takeaway: High earners see proportionally larger savings (up to $3,700 annually), but AMT limitations and complex timing strategies require careful planning.
Key Takeaway: High earners can save up to $3,700 annually from the doubled SALT cap, but AMT limitations and timing strategies require sophisticated planning.

Families with children who need to balance SALT benefits with other family tax priorities
How families should evaluate the SALT changes
Families face a critical decision: take the $30,000 standard deduction (MFJ) or itemize to claim the higher SALT deduction. The break-even point has shifted significantly with the doubled cap.
Family break-even analysis
To benefit from itemizing, your total itemized deductions must exceed $30,000. With the new $20,000 SALT cap, you need only $10,000 in other deductions (mortgage interest, charitable giving, medical expenses) to break even.
Example family scenario:
Interaction with family credits
The SALT deduction reduces your Adjusted Gross Income, which can help you qualify for or maximize:
Key takeaway: Families in high-tax areas with modest mortgages and charitable giving can now more easily exceed the standard deduction threshold, creating additional planning opportunities.
Key Takeaway: Families can more easily exceed the $30,000 standard deduction with the doubled SALT cap, potentially unlocking additional tax credits and savings.
