The property tax deduction lets you subtract real estate taxes you paid on your home from your federal taxable income, but only if you itemize on Schedule A and only up to the combined state and local tax cap. For 2026, that cap is $40,400 for most filers and $20,200 if you’re married filing separately. The tax has to be based on your property’s assessed value and levied by a general government, and you deduct what was actually paid to the taxing authority during the year.
Does Itemizing Beat the Standard Deduction
The property tax deduction only helps if you itemize, and itemizing only helps if your deductible expenses together exceed the standard deduction for your filing status. For 2026 the standard deduction is $16,100 for single filers and married filing separately, $32,200 for married filing jointly, and $24,150 for head of household.1Internal Revenue Service.

Add up your property taxes, state income or sales taxes, mortgage interest, charitable contributions, and other Schedule A items. If the total lands below your standard deduction, itemizing costs you money. Run the numbers each filing season. The standard deduction moves with inflation, and your own expenses shift year to year.
Which Property Taxes Qualify
A property tax is deductible only if it’s based on the assessed value of your real estate and charged uniformly across the community to fund general government services. Most county and municipal property taxes clear that bar. You’ll see the charge on your annual tax bill, calculated as a percentage of what the local assessor says your property is worth.2Internal Revenue Service. Publication 530 (2025), Tax Information for Homeowners
Several charges that appear on the same bill don’t qualify:
- Service fees for trash pickup, water, or sewer are payments for a specific benefit to your property, not a general tax.
- Local improvement assessments for new sidewalks, street paving, or similar projects that increase your property’s value aren’t deductible. You can add them to your home’s cost basis instead, which may reduce your taxable gain when you sell.
- Homeowners association dues are private contractual obligations, not government taxes.
Many jurisdictions bundle everything onto one statement, which makes it easy to overclaim. Read the bill line by line and separate the value-based tax from the rest.
The value-based portion of an annual vehicle registration fee also counts, though it’s a personal property tax rather than a real estate tax. Flat registration charges don’t qualify, and many states blend both types into one bill, so check the breakdown.3Internal Revenue Service.

The SALT Cap
Your property tax deduction is bundled with your state and local income taxes (or sales taxes, if you pick those instead) into a single category called SALT. Federal law caps the total. However much you paid in combined property and income taxes, you can only deduct up to the ceiling.
For 2026, the cap is $40,400 for most filers and $20,200 for married filing separately. It rises by roughly 1% per year through 2029 and then drops back to $10,000 unless Congress extends it again.4Internal Revenue Service. Real Estate (Taxes, Mortgage Interest, Points, Other Property Expenses) 5
High-Income Phasedown
If your modified adjusted gross income exceeds $505,000 in 2026, the $40,400 cap starts shrinking. For every dollar over that threshold, the cap drops by 30 cents, bottoming out at $10,000. The threshold itself rises by 1% per year through 2029. Households in that income range often find the effective deduction much smaller than the headline cap.
The AMT
If you owe the Alternative Minimum Tax, the property tax deduction disappears for AMT purposes. State and local taxes get added back into income when your AMT is figured. High earners in high-tax states are the most likely to run into this. If AMT has hit you before, factor it in before assuming SALT will lower what you actually owe.
Rentals and Business Property
The SALT cap only applies to taxes on your personal residence. Property taxes on rental real estate go on Schedule E, and taxes on business property go on Schedule C. Neither is subject to the SALT cap.
For a mixed-use property such as a vacation home you rent part of the year and use yourself the rest, the taxes get split. The personal-use portion falls under the SALT cap on Schedule A. The rental-use portion goes on Schedule E without a cap. The allocation matters, especially if your personal SALT is already close to the limit.
Buying or Selling During the Year
When a home changes hands, the property tax deduction is split between buyer and seller by the number of days each owned the home. Federal law treats the seller as paying the taxes for every day before the sale and the buyer for the sale date forward.5Office of the Law Revision Counsel. 26 USC 164 – Taxes
That split holds regardless of who actually wrote the check. If the buyer paid the full year’s tax at closing, only the buyer’s share from the sale date forward is deductible. The seller’s portion the buyer covered gets added to the buyer’s cost basis in the home. Your closing statement should break this out, but check the math.2Internal Revenue Service. Publication 530 (2025), Tax Information for Homeowners
One trap catches buyers often. If you agree to pay the seller’s delinquent taxes from prior years, those aren’t deductible at all. They go into your home’s cost basis as part of the purchase price.
What Amount to Use and What to Keep
The deductible amount is what was actually paid to the taxing authority during the calendar year. Not what was billed. Not what sits in an escrow account waiting to be sent. That distinction trips up more people than any other feature of this deduction.
If your lender pays property taxes from an escrow account, look at Form 1098, which lenders send by the end of January. Box 10 may report the real estate taxes the lender disbursed to the local government during the year. The figure you want is what the lender paid out, not what you deposited.6Internal Revenue Service. Instructions for Form 1098 – Introductory Material
If you pay the municipality directly, keep your tax bills and proof of payment: canceled checks, bank statements, or online confirmations. The payment date determines which tax year the deduction falls in, no matter when the bill was issued or which period it covers. A December 2026 payment on a bill covering early 2027 belongs on your 2026 return.
How to Enter It on Schedule A
Real estate taxes go on Line 5b of Schedule A (Form 1040). Deductible personal property taxes, such as the value-based portion of a vehicle registration, go on Line 5c. State and local income or sales taxes go on Line 5a. The sum of the three lines is your SALT deduction, capped at $40,400 for 2026.3Internal Revenue Service. Instructions for Schedule A (Form 1040) (2025) – Specific Instructions
Your completed Schedule A total transfers to Line 12 of Form 1040 and reduces your taxable income. Hold on to your tax bills, Form 1098, and payment records for at least three years from your filing date, which is the general IRS audit window.7Internal Revenue Service.
