The Two Hurdles
Property taxes are deductible on your federal return. That's the easy part. Whether the deduction actually saves you money depends on clearing two separate hurdles, and plenty of homeowners clear neither:
- You have to itemize. The deduction only exists if you skip the standard deduction and itemize on Schedule A instead. Since the standard deduction roughly doubled in 2018, most taxpayers no longer itemize.
- The SALT cap limits the total. State and local taxes (property taxes plus either state income taxes or sales taxes) are deductible only up to a combined cap.
The SALT Cap Is Now $40,400
The $10,000 cap that applied from 2018 through 2024 is gone for now. The 2025 tax law (the "One Big Beautiful Bill Act") raised it and set it on a schedule:
| Tax year | SALT cap (single or married filing jointly) | Married filing separately |
|---|---|---|
| 2018–2024 | $10,000 | $5,000 |
| 2025 | $40,000 | $20,000 |
| 2026 | $40,400 | $20,200 |
| 2027–2029 | Rises 1% a year | Half the full cap |
| 2030 onward | Back to $10,000 unless Congress acts | $5,000 |
Note that the cap is per return, not per person: a married couple filing jointly gets the same $40,400 as a single filer.
High earners get less
Above a modified adjusted gross income of $500,000 ($505,000 for 2026), the cap shrinks by 30 cents for every dollar over the threshold, but never below $10,000. In 2026 it bottoms out at $10,000 once income reaches roughly $606,000. Example: a household with $560,000 of MAGI in 2026 is $55,000 over, so its cap drops by $16,500, from $40,400 to $23,900.
How the Deduction Works
On Schedule A, you add up your deductible state and local taxes:
| Tax Type | Deductible? |
|---|---|
| Property taxes on your home | Yes |
| Property taxes on a second home or land | Yes |
| State and local income taxes | Yes (or sales taxes, but not both) |
| Property taxes on rental properties | Not here. Deducted on Schedule E as a business expense instead, with no cap. |
| Assessments for local improvements (sidewalks, sewers) | Generally no. These add to your cost basis. |
| HOA fees | No |
The total, up to the cap, gets added to your other itemized deductions (mortgage interest, charitable donations, some medical expenses). If that sum beats your standard deduction, itemizing wins.
Two Worked Examples
Homeowner in New Jersey (high-tax state)
| Property tax bill | $11,400 |
| State income tax paid | $7,200 |
| Total SALT before cap | $18,600 |
| Deductible SALT, old $10,000 cap (2024) | $10,000 |
| Deductible SALT, new $40,400 cap (2026) | $18,600 (all of it) |
| Mortgage interest | $9,800 |
| Total itemized deductions (2026) | $28,400 |
Under the old cap, $8,600 of taxes this homeowner actually paid got no deduction at all. Under the new one, every dollar counts. Whether that helps depends on filing status, because the standard deduction rose too (for 2026, $16,100 single and $32,200 married filing jointly):
- Single filer: $28,400 itemized beats the $16,100 standard deduction by $12,300. The property tax deduction is doing real work.
- Married couple: $28,400 is still below the $32,200 standard deduction, so they take the standard deduction and the higher cap changes nothing for them, unless charitable gifts or other deductions push them over.
That split is the most common surprise of the new cap: it matters most to single homeowners and to couples with very large tax bills, mostly in New Jersey, New York, California, Illinois and Connecticut.
Homeowner in Tennessee (low-tax state)
| Property tax bill | $1,900 |
| State income tax | $0 (Tennessee doesn't tax wages) |
| Sales tax deduction (IRS table estimate) | $1,450 |
| Total SALT | $3,350 |
| Mortgage interest | $7,100 |
| Total itemized deductions | $10,450 |
This homeowner's itemized total falls well short of the standard deduction. They take the standard deduction, and their property taxes provide zero federal tax benefit. Nothing wrong happened here; the standard deduction is simply the better deal.
Who Actually Benefits
Putting it together, the property tax deduction tends to matter for people who check most of these boxes:
- Large mortgage with significant interest (pushes you over the standard deduction)
- High property tax bill, high state income taxes, or both
- Filing in a high-tax state
If you own your home outright and live in a low-tax state, you almost certainly take the standard deduction and this whole topic is academic.
Common Mistakes
- Deducting the wrong year. You deduct taxes in the year you actually paid them, not the year they were assessed. If your escrow paid the bill in January 2026, that's a 2026 deduction even if the bill was for 2025.
- Using the escrow contribution instead of the actual tax paid. What you deposited into escrow isn't deductible; what the servicer paid out to the county is. Your Form 1098 shows the right number.
- Forgetting rental properties go on Schedule E. Landlords deduct property taxes as a business expense with no SALT cap. Putting them on Schedule A wastes the deduction. More on this in our guide to property taxes on rental properties.
- Deducting special assessments. That one-time charge for the new sewer line isn't a deductible tax.
Bottom Line
Property taxes are deductible, but only if you itemize, and only up to the SALT cap, which is $40,400 for 2026 (less above $505,000 of income) and is scheduled to fall back to $10,000 in 2030. Run both numbers (standard vs. itemized) before assuming the deduction helps you. Tax software does this automatically; if you use a preparer, they should show you the comparison.
