If you own a home in New York, you already know how heavy the tax burden can feel. Property taxes and state income taxes can feel overwhelming. Since 2018, the federal SALT deduction cap has made things tougher by limiting how much of those taxes you can deduct on your federal return. For many families on Long Island and throughout the NYC suburbs, that $10,000 cap has been a real financial hit.
A new federal law called the One Big Beautiful Bill Act (OBBBA) changes that starting in tax year 2025. For many New York homeowners, this shift will increase how much of what you already pay can actually count on your federal return.
Here is a clear look at what changed, who benefits most, and what to keep in mind as you plan for 2025.
SALT stands for State and Local Taxes. If you itemize deductions on your federal return, you can deduct eligible state and local taxes you paid during the year.
SALT typically includes:
You only benefit from SALT if you itemize. Taxpayers who take the standard deduction do not receive any direct benefit from SALT.
The OBBBA temporarily raises the SALT cap for several years.
Prior rules (2018–2024):
New rules (2025–2029 under current law):
Income Phase‑Down (Important): The full $40,000 cap does not apply to everyone. Once your modified adjusted gross income (MAGI) passes certain thresholds (around $500,000 for most filers and $250,000 for married filing separately), the expanded cap begins to shrink. It can never go below the original $10,000 limit, or $5,000 for married filing separately.
Homeowners in high‑tax states benefit the most, especially New Yorkers whose property taxes alone often fall between $12,000 and $20,000.
You’re likely to benefit if:
Middle‑income and upper‑middle‑income homeowners fall into the strongest benefit group.
A homeowner pays:
Total SALT: $26,000.
Before 2025: Only $10,000 was deductible.
Starting in 2025: They may be able to deduct the full $26,000, assuming they itemize and do not lose the expanded amount due to phase‑down.
The amount paid to the state doesn’t change - but the federal return finally reflects more of it.
New York’s Pass‑Through Entity Tax (PTET) allows S corps and partnerships to pay certain NY taxes at the entity level. This can make those taxes deductible as business expenses for federal purposes.
Even with the higher SALT cap:
If you use PTET, it’s worth reevaluating your approach for 2025.
Here is a straightforward way to prepare:
Planning early helps avoid surprises during tax season.

Does the higher SALT cap mean I should stop taking the standard deduction?
Not automatically. It depends on your total itemized deductions. For some, itemizing will now make sense again. For others, the standard deduction will still provide the better result.
Will the higher SALT cap stay this high permanently?
No. Under current law, the expanded cap runs from 2025 through 2029 and returns to $10,000 beginning in 2030.
Does New York follow the same rules?
Not always. New York often decouples from federal tax changes. Your federal and state returns may differ.
