The real estate tax deduction lets you write off state and local property taxes on your home when you itemize on Schedule A, subject to a combined cap on all state and local taxes. For the 2026 tax year, that cap is $40,400 for most filers, up sharply from the $10,000 limit that ran from 2018 through 2024. Whether claiming it actually cuts your tax bill depends on whether your total itemized deductions beat the standard deduction, which for 2026 is $16,100 for single filers and $32,200 for married couples filing jointly.
Which Property Taxes Qualify
The deduction covers state and local taxes charged on the assessed value of your real property, as long as the tax is imposed at a uniform rate across the community and funds general government services like schools, roads, and emergency response.1Internal Revenue Service. Instructions for Schedule A (Form 1040) Tax professionals call this an “ad valorem” tax, and it’s the main line item on most homeowners’ bills.
Charges tied to a specific benefit to your property don’t count. Assessments for new sidewalks, sewer lines, or street paving are treated as capital improvements because they increase your property’s value. Trash collection fees, water charges, and similar service billing are also non-deductible. If your bill bundles these with the general property tax, only the ad valorem portion qualifies.2Internal Revenue Service. Publication 530 – Tax Information for Homeowners Your assessment notice should break these out, and that breakdown is worth checking before you file.
A few other items that look like property taxes but aren’t deductible:
- Taxes on real property located outside the United States lost their deductibility starting in 2018.3Office of the Law Revision Counsel. 26 USC 164 – Taxes
- Transfer taxes and stamp taxes at closing. If you’re the buyer, they get added to your cost basis; if you’re the seller, they reduce your amount realized. Neither side gets a deduction.2Internal Revenue Service. Publication 530 – Tax Information for Homeowners
- Homeowners association dues, which are private charges rather than government-imposed taxes.
The SALT Cap for 2026
The Tax Cuts and Jobs Act of 2017 first capped total state and local tax deductions at $10,000. The One Big Beautiful Bill Act, signed on July 4, 2025, raised that cap. For the 2026 tax year, the cap is $40,400 for single filers, married couples filing jointly, and heads of household. Married individuals filing separately face a cap of $20,200.3Office of the Law Revision Counsel. 26 USC 164 – Taxes
The cap covers your combined deductions for state and local income taxes (or sales taxes, if you elect that instead), personal property taxes, and real property taxes together. Once your total hits the ceiling, additional payments don’t reduce your federal tax bill.
Phase-Down for Higher Incomes
The increased cap shrinks for taxpayers with modified adjusted gross income above $505,000 in 2026 ($252,500 for married filing separately). Above that threshold, the cap drops by 30 cents for every dollar of excess income, though it never falls below $10,000.3Office of the Law Revision Counsel. 26 USC 164 – Taxes In practice, a joint filer earning around $606,000 or more is effectively back at the old $10,000 cap. If your income is anywhere near that range, run the math carefully before you assume the higher limit applies.
What Happens After 2029
The increased cap adjusts for inflation at 1% per year through 2029. In 2030, it reverts to $10,000 ($5,000 for married filing separately) unless Congress acts again.3Office of the Law Revision Counsel. 26 USC 164 – Taxes
Does Itemizing Beat the Standard Deduction?
The property tax deduction only saves you money if your total itemized deductions on Schedule A exceed the standard deduction. For 2026:4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- Single: $16,100
- Married filing jointly: $32,200
- Head of household: $24,150
- Married filing separately: $16,100
Add your property taxes to any state income tax, mortgage interest, charitable contributions, and other qualifying expenses. With the higher SALT cap for 2026, more homeowners in high-tax areas will find itemizing pays off compared to recent years, when the $10,000 ceiling made it hard to clear the standard deduction threshold. If your itemized total lands close to the standard deduction, run both calculations. Sometimes the standard deduction wins on simplicity alone.
Who Can Claim It
You need to own the property and be legally obligated to pay the taxes on it. Paying someone else’s property taxes, such as a parent’s, doesn’t earn you a deduction because you had no legal obligation to make the payment.2Internal Revenue Service. Publication 530 – Tax Information for Homeowners
Most taxpayers use the cash method, meaning you deduct property taxes in the year you actually pay them, regardless of what period the bill covers. A bill for the second half of 2026 that you pay in January 2027 goes on your 2027 return. You can also only deduct taxes that have been formally assessed by the local taxing authority; prepaying an estimated future bill that hasn’t been levied yet doesn’t create a current deduction.
If your lender pays property taxes from an escrow account, the deduction belongs to the year the lender actually sends the money to the taxing authority, not when you deposit funds into escrow. Those dates are often different, and the distinction matters.2Internal Revenue Service. Publication 530 – Tax Information for Homeowners
Co-op Apartment Owners
If you own shares in a cooperative housing corporation, you can deduct your proportionate share of the building’s property taxes even though the co-op holds title and pays the tax bill directly. Your share is generally based on the percentage of the corporation’s stock you own, and the co-op should provide an annual statement showing your allocable portion.5Office of the Law Revision Counsel. 26 USC 216 – Deduction of Taxes, Interest, and Business Depreciation by Cooperative Housing Corporation Tenant-Stockholder
Rental Properties and Home Offices Sit Outside the Cap
Property taxes on rental real estate are deducted as a business expense on Schedule E, not as an itemized deduction on Schedule A. The SALT cap does not apply.6Internal Revenue Service. Instructions for Schedule E (Form 1040) If you own rental property in a high-tax jurisdiction, every dollar of property tax reduces your rental income with no $40,400 ceiling.
Self-employed taxpayers who use part of their home exclusively and regularly as their principal place of business can split their property taxes. The business-use portion is deducted through Form 8829, while the personal-use portion stays on Schedule A under the SALT cap.7Internal Revenue Service. Topic No. 509 – Business Use of Home A dedicated home office covering 15% of your home’s square footage, for instance, would shift 15% of your property taxes outside the SALT cap.
Splitting the Deduction When You Buy or Sell
When a home changes hands, the IRS splits the property tax deduction between buyer and seller based on the number of days each party owned the property during the tax year. The seller gets the deduction for the period before the closing date, and the buyer gets it starting on the closing date. This allocation applies regardless of which party actually wrote the check at settlement.2Internal Revenue Service. Publication 530 – Tax Information for Homeowners
Your settlement statement will show exactly how property taxes were credited between the two sides. Use that figure rather than calculating the split yourself.
One trap catches buyers. If the seller owed delinquent property taxes from prior years and you agreed to pay them as part of the deal, you cannot deduct those back taxes. They get added to your cost basis in the property, which can reduce any taxable gain when you eventually sell.2Internal Revenue Service. Publication 530 – Tax Information for Homeowners
How to Claim It on Your Return
Report deductible real estate taxes on line 5b of Schedule A (Form 1040). Your combined state and local taxes then flow to line 5e, where the SALT cap is applied.1Internal Revenue Service. Instructions for Schedule A (Form 1040)
Finding Your Property Tax Amount
If your lender handles property tax payments through escrow, check Form 1098 (Mortgage Interest Statement). Box 10 may show the real estate taxes paid from your escrow account during the year, though lenders are not required to fill in this box.8Internal Revenue Service. Instructions for Form 1098 – Mortgage Interest Statement If Box 10 is blank, contact your lender or check your annual escrow statement for the amounts actually disbursed to the taxing authority. If you pay taxes directly to your local assessor, your annual tax bills and payment receipts are your documentation. Keep copies of both.
If You Get a Property Tax Refund
If your county or municipality refunds part of your property taxes in the same year you paid them, reduce your deduction for that year by the refund. A refund that arrives in a later year is trickier: if you deducted the original payment and it actually reduced your tax, you may need to report some or all of the refund as income. You only include the portion that provided a tax benefit in the earlier year.9Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income If you took the standard deduction in the year you paid the taxes, the refund isn’t taxable because the original payment never reduced your tax.
Recordkeeping
Hold onto your property tax receipts, Form 1098, settlement statements, and any refund documentation for at least three years from the date you filed the return claiming the deduction.10Internal Revenue Service. How Long Should I Keep Records Keeping them longer is reasonable if your return was complex.
