Quick Answer
The SALT deduction cap is more complex than just $40,000. For married filing jointly, you can deduct up to $40,000 in general state and local taxes, plus an additional $20,000 for primary residence property taxes, for a total of $60,000. Single filers get $20,000 plus $20,000, totaling $40,000 maximum.

The SALT deduction cap isn't simply $40,000
The 2026 SALT deduction rules create a two-part system rather than a single cap. The actual limit depends on your filing status and what types of state and local taxes you're deducting.
For married filing jointly:
For single filers:
So while $40,000 is the base limit for married couples, it's not the full story.
What counts toward each limit?
General SALT limit ($40,000 MFJ / $20,000 Single):
Additional primary residence allowance ($20,000):
Example: How the limits work together
Let's say you're married and paid these taxes in 2026:
Option 1 - Use both limits:
Option 2 - Use only general limit:
Both options give the same result here, but Option 1 preserves $22,000 of your general SALT limit for future use.
When the distinction matters
The two-limit system becomes important when:

Best for high-income taxpayers with substantial state tax bills who may hit the limits
Strategic planning when you'll hit the SALT limits
For high earners, the question isn't whether you can deduct your SALT payments—it's how to maximize the deduction within the new limits and plan around them.
When you'll max out the limits
You'll likely hit the SALT limits if:
Example: High earner hitting the limits
Married couple earning $500,000 in California:
Maximum deduction allowed:
Advanced planning strategies
Timing state estimated payments: Accelerate or defer quarterly payments between December and January to optimize deductions across tax years.
Multiple residence strategy: If you have homes in multiple states, consider which should be your "primary residence" for the $20,000 property tax allowance.
Retirement account contributions: Since SALT deductions don't reduce AGI, maximize 401(k) and IRA contributions to reduce state income tax bills.
The expanded limits help significantly, but high earners in expensive areas will still hit the caps and need sophisticated planning.
Key takeaway: High earners will benefit significantly from the increased limits but may still max out at $60,000, requiring strategic tax planning around the caps.
Key Takeaway: High earners will benefit from the increased $60,000 SALT limit but may still max out, requiring strategic timing of payments and multi-year tax planning.

Best for families trying to understand how the SALT limits affect their overall tax planning
How SALT limits affect family tax planning
For families, understanding the SALT limits helps determine whether itemizing beats the standard deduction and how to coordinate with other family tax benefits.
Family-specific considerations
Families often have:
Example: Family of four with $120,000 income
Their SALT payments:
Deduction calculation:
Other itemized deductions:
Since $41,800 exceeds the $30,000 standard deduction, this family benefits significantly from itemizing—saving approximately $2,832 in taxes (24% of the $11,800 difference).
The sweet spot for families
Most families with property taxes between $10,000-$25,000 will find the expanded SALT deduction makes itemizing worthwhile, especially when combined with mortgage interest.
Unlike high earners, most families won't hit the SALT limits but will benefit from the increased flexibility to deduct their full property tax bills.
Key takeaway: Most families won't hit the new SALT limits but will benefit significantly from being able to deduct their full property tax and state income tax amounts when itemizing.
Key Takeaway: Most families won't approach the SALT limits but benefit significantly from deducting full property tax amounts, often making itemizing worthwhile when combined with mortgage interest.
