Quick Answer
The 2026 SALT deduction cap increased to $15,000 for single filers and $20,000 for married couples, up from the previous $10,000 limit. However, before 2018, there was no cap at all – taxpayers could deduct unlimited state and local taxes, which averaged $18,400 for affected households.

How the SALT cap has changed over time
The State and Local Tax (SALT) deduction has undergone significant changes since 2017. Before 2018, there was no limit on how much you could deduct for state and local taxes. The Tax Cuts and Jobs Act imposed a $10,000 cap starting in 2018, and the One Big Beautiful Bill Act raised it to $15,000 for single filers and $20,000 for married filing jointly in 2026.
Historical comparison: What taxpayers actually deducted
According to IRS Statistics of Income data, before the cap was implemented:
Example: $125,000 household in New Jersey
Let's look at how a married couple earning $125,000 in New Jersey would fare under each system:
Pre-2018 (No cap):
2018-2025 ($10,000 cap):
2026 ($20,000 cap for MFJ):
Who benefits most from the 2026 changes
States with the biggest impact
The Tax Foundation data shows average property tax burdens by state. Combined with state income taxes, residents in these states benefit most:
1. New Jersey: Average combined SALT burden $17,600
2. New York: Average combined SALT burden $16,200
3. Connecticut: Average combined SALT burden $15,800
4. California: Average combined SALT burden $14,900
What you should do
For 2026 tax planning:
1. Re-evaluate itemizing: If you previously switched to the standard deduction due to the SALT cap, run the numbers again
2. Consider tax timing: If you live in a high-tax state, the higher SALT cap might make December property tax prepayments worthwhile
3. Review your withholding: The additional deduction might mean you're over-withholding on federal taxes

Key takeaway: The 2026 SALT cap increase provides meaningful relief for middle and upper-middle class families in high-tax states, potentially saving $1,200-$3,600 annually compared to the 2018-2025 rules.

Key Takeaway: The 2026 SALT cap increase to $15,000/$20,000 restores much of the deduction that was lost in 2018, potentially saving middle-class families in high-tax states $1,200-$3,600 annually.
SALT deduction limits by tax year and filing status
| Tax Years | Single Filers | Married Filing Jointly | Average Pre-2018 Deduction |

| 2018-2025 | $10,000 | $10,000 | Capped at $10,000 |
| 2026+ | $15,000 | $20,000 | Projected $16,800 |

Taxpayers earning over $200,000 who are most affected by SALT limitations
Why high earners still face SALT challenges
Even with the 2026 increases, high-earning taxpayers in expensive states often exceed the new caps. A Manhattan couple earning $500,000 might pay $25,000 in state income tax plus $30,000 in property taxes – far exceeding the $20,000 married filing jointly limit.
Strategic considerations for high earners
Timing strategies:
Business structure implications:
Example: $400,000 couple in California
Total SALT burden: ~$45,000 (state income + property)
2026 deduction: Limited to $20,000
Lost deduction: $25,000
Additional federal tax: ~$9,250 (37% bracket)
While the 2026 changes help, this couple still pays $6,175 more in federal taxes than they would without any SALT cap.
Key takeaway: High earners benefit from the 2026 SALT increases but still face significant limitations – comprehensive tax planning becomes essential for optimal results.

Families with children who need to balance SALT deductions with other family tax benefits
How families should approach SALT deduction planning
Families face unique considerations with SALT deductions because they must balance state tax savings with federal credits and deductions that phase out at higher incomes.
Family-specific scenarios
Young families with mortgages:
The combination of mortgage interest, SALT deductions, and child tax credits often makes itemizing worthwhile. A family earning $95,000 with $8,000 in mortgage interest and $12,000 in SALT might save $2,200 by itemizing instead of taking the $30,000 standard deduction.
Families considering private school:
Some states offer tax credits for private school tuition that work alongside federal SALT deductions. However, these often count toward the SALT cap, requiring careful planning.
Multi-generational planning:
Families supporting elderly parents should consider whether property tax payments on parents' homes qualify for the SALT deduction and how this affects overall family tax strategy.
Education savings coordination
Families should coordinate SALT planning with 529 plan contributions, especially in states offering state tax deductions for 529 contributions (which may count toward SALT limits in some jurisdictions).
Key takeaway: Families benefit most from SALT increases when they coordinate with mortgage interest, child credits, and education planning for comprehensive tax optimization.
