Will the higher SALT deduction cap lower your 2026 tax bill? For taxpayers in high-tax states, the answer may be yes—but the benefit is not as straightforward as the $40,000 headline suggests. Income limits, phaseouts, and scheduled changes may determine how much of the deduction you can actually claim.
What Is SALT?
SALT stands for State and Local Taxes. Taxpayers who itemize deductions can deduct certain taxes paid to state and local governments from their federal taxable income. These include state and local real estate taxes, personal property taxes, and either state and local income taxes or general sales taxes.
The cap
For tax years 2018 – 2024, the maximum SALT deduction was generally $10,000, or $5,000 for married taxpayers filing separately.
For 2025, the OBBBA increased the cap to $40,000, or $20,000 for married filing separately (MFS). This can provide a significant benefit to taxpayers who itemize deductions, particularly those living in states with high income and property taxes, such as California, Oregon, and New York.
For 2026, the cap increases by 1% to $40,400, or $20,200 for MFS. The SALT cap is now indexed for inflation and will increase 1% each year until 2029.
The income threshold
The old $10,000 SALT cap didn’t have an income-based phase-down. The new SALT deduction does.
For 2025, the phase-down begins when a taxpayer’s modified adjusted gross income (MAGI) exceeds $500,000 for all filing statuses except MFS. For MFS, the threshold is $250,000.
For 2026, those thresholds increase by 1%. The phase-down begins at $505,000, or $252,500 for MFS.
Once a taxpayer exceeds the applicable threshold, the SALT cap is reduced by 30% of the excess MAGI. However, the deduction limit can’t be reduced below $10,000, or $5,000 for MFS.
How does the phase-down work?
Let’s look at a simple example.
Say a Single taxpayer has a MAGI of $550,000 in 2026. The phase-down begins at $505,000, meaning the taxpayer is $45,000 over the threshold.
The SALT cap is reduced by 30% of that $45,000:
$45,000 × 30% = $13,500
The standard 2026 SALT cap is $40,400, so we subtract the $13,500 reduction:
$40,400 − $13,500 = $26,900
That means this taxpayer’s maximum SALT deduction would be $26,900, assuming they paid at least that much in qualifying state and local taxes and otherwise qualify to claim the deduction.
As income continues to increase, the available deduction continues to decrease until the taxpayer reaches the minimum $10,000 SALT cap.
So, what’s the big change for 2026?
From 2025 to 2026? Not much.
The SALT deduction isn’t undergoing another major overhaul. Instead, 2026 brings the first scheduled increase to the new limits. The general cap rises from $40,000 to $40,400, while the income threshold rises from $500,000 to $505,000.
For most taxpayers, the difference between the 2025 and 2026 rules will be relatively minor. The much bigger change was the jump from the old $10,000 SALT cap to the new $40,000 cap beginning in 2025.
If you claim the standard deduction, this change will have no impact on your tax return. If you itemize, you may see a small positive effect on your bottom line at tax time.
Taxpayers who itemize deductions on Schedule A and live in high-tax states (such as California, New York, or New Jersey) stand to benefit most. If you claim the standard deduction or pay less than $10,000 in state and local taxes, the higher cap will not change your tax liability.
The phase-down begins once your Modified Adjusted Gross Income (MAGI) exceeds $505,000 for Single, Head of Household, or Married Filing Jointly filers. For Married Filing Separately (MFS), the threshold begins at $252,500. If your income is below these amounts, you can claim up to the full $40,400 cap.
No. Even if your income far exceeds the $505,000 threshold, the law specifies a floor—meaning your deduction limit cannot be reduced below $10,000 ($5,000 for Married Filing Separately).
You can combine:
State and local real estate (property) taxes.
Personal property taxes.
Either state and local income taxes or general sales taxes (you must choose one or the other).
Note: Federal taxes, transfer taxes, and HOA fees do not qualify.
Under current rules, the cap and phase-out thresholds will continue to rise by 1% each year through 2029. Unless modified by future legislation, the SALT cap is scheduled to revert back to $10,000 ($5,000 for MFS) starting in tax year 2030.
