How Much of Your Property Taxes Are Tax Deductible?

How much of your property taxes are tax deductible depends on two things: whether you itemize on Schedule A, and how much room is left under the state and local tax (SALT) cap after your state income or sales taxes are counted. For the 2026 tax year, that cap is $40,400 for most filers and covers real estate taxes, personal property taxes, and either state income taxes or state sales taxes combined. Property taxes above what fits under the cap give you no federal benefit, and neither do any property taxes at all if your total itemized deductions come in below the standard deduction.

The SALT Cap Is the Main Limit

The Tax Cuts and Jobs Act capped the SALT deduction at $10,000 starting in 2018. The One Big Beautiful Bill Act restructured the cap beginning in 2025, and for 2026 the ceiling is $40,400 for most filers and $20,200 for married filing separately.¹ The cap and its income threshold increase 1% each year through 2029, then revert to a flat $10,000 in 2030.

Everything eligible sits under one ceiling. You add up your real estate taxes, your personal property taxes, and either your state income taxes or your state sales taxes (you have to pick one), and the total cannot exceed $40,400. If your state income tax alone is $35,000 and your property tax bill is $10,000, you have $45,000 in eligible SALT and can deduct $40,400. The extra $4,600 is lost. In a high-income-tax state where state taxes alone eat the whole $40,400, your property tax deduction effectively disappears.

Phase-Down for Higher Incomes

The $40,400 cap starts shrinking once modified adjusted gross income passes $505,000 ($252,500 for married filing separately). Above that line, the cap drops 30 cents for every dollar of excess income, with a floor of $10,000 ($5,000 for married filing separately).²

The math for a joint filer at $600,000 in modified AGI with $15,000 in property taxes and $12,000 in state income taxes:

Total eligible SALT: $27,000
Excess income: $600,000 − $505,000 = $95,000
Cap reduction: $95,000 × 30% = $28,500
Reduced cap: $40,400 − $28,500 = $11,900
Deductible SALT: $11,900

At roughly $606,000 in modified AGI, the reduced cap hits the $10,000 floor for joint filers.

You Only Get the Deduction If You Itemize

Property taxes only reduce your federal tax if you itemize on Schedule A. For 2026, the standard deduction is $32,200 for married couples filing jointly, $16,100 for single filers and married filing separately, and $24,150 for heads of household.¹

Itemizing pays off only when your capped SALT deduction plus your mortgage interest, charitable contributions, and other itemized deductions exceeds the standard deduction. A married couple claiming the full $40,400 in SALT still needs at least another $11,800 in other deductions before itemizing beats the standard deduction. Run the numbers each year; the choice is not binding from one year to the next.

Which Charges on the Bill Count

To be deductible, a property tax has to be charged by a state or local government, applied uniformly across the jurisdiction, and based on assessed value. The IRS calls this an ad valorem tax, and it covers real estate taxes on your primary home, vacation homes, and land held for personal use.³ Vehicle registration fees calculated as a percentage of market value qualify as personal property taxes; flat registration fees do not.

Several charges that appear on property tax bills do not count:

Local improvement assessments for new sidewalks, streets, or sewer lines. These are capital costs that add to your property’s basis.³
Service fees for trash collection, water, or sewer usage, even when included in the tax bill.
Transfer or stamp taxes paid at closing. Buyers add these to basis; sellers treat them as selling expenses.
Late payment penalties and interest on those penalties.⁴

Charges to maintain or repair existing infrastructure are deductible; charges to build new infrastructure are not. Resurfacing an old sidewalk counts; installing a new one does not.³

Timing matters too. You deduct property taxes in the year you actually paid them. A December 2026 bill you pay in January 2027 belongs on your 2027 return.

If Your Lender Pays Through Escrow

When your mortgage servicer holds property taxes in escrow, the deductible figure is what the lender actually disbursed to the taxing authority during the calendar year, not what you deposited into escrow. Those numbers often differ because tax collectors get paid on their own schedule.

Your lender reports the amount paid from escrow in Box 10 of Form 1098, which can also include escrow-paid insurance premiums. Check the property tax portion against your annual escrow statement before putting it on Schedule A.⁵

If You Bought or Sold During the Year

When a property changes hands mid-year, federal law splits the property tax between buyer and seller based on how many days each owned the home during the real property tax year. This allocation controls for tax purposes regardless of who wrote the check at closing.⁶ The seller’s share runs from the start of the tax year through the day before closing; the buyer’s share starts on the closing date. Your closing disclosure shows the proration, and that is the figure to use on Schedule A.⁷

Co-op Owners

Shareholders in a cooperative housing corporation can deduct their proportionate share of the co-op’s real estate taxes. The share is generally based on the shareholder’s percentage of the corporation’s total outstanding stock, though a co-op can elect a unit-specific allocation reflecting the actual cost attributable to each dwelling.⁸ The corporation should send you a statement with your allocable share. It goes on Schedule A and counts toward the SALT cap like any other property tax.

Situations Where the Rule Above Does Not Apply

Foreign Property

Property taxes on real estate located outside the United States are not deductible as an itemized deduction. The TCJA eliminated that deduction starting in 2018, and the Schedule A instructions still limit Line 5b to state and local real estate taxes.² A personal vacation home abroad gives you no federal property tax deduction.

Rental and Business Use

Property taxes on rental real estate are a business expense on Schedule E, not an itemized deduction, and they bypass the SALT cap entirely. You can claim them whether or not you itemize.⁹ The same is true for real estate used in a trade or business.

If part of your home qualifies as a home office, the business-use percentage of your property tax comes off on Form 8829 outside the SALT cap.¹⁰ The remaining personal-use share still runs through Schedule A subject to the $40,400 limit. A 20% business use of the home means 20% of the tax goes on the business return and 80% on Schedule A.

The AMT Can Take It Back

State and local tax deductions, property taxes included, are completely disallowed when the alternative minimum tax is calculated. For taxpayers whose regular tax runs close to their AMT liability, the property tax deduction may produce little or no actual savings. For 2026 the AMT exemption is $90,100 for single filers and $140,200 for joint filers, phasing out beginning at $500,000 and $1,000,000 respectively.¹ High-income filers in high-tax states are the most likely to see AMT eat into their SALT benefit.

If You Get a Property Tax Refund Later

A refund or rebate of property taxes you deducted in a prior year is taxable in the year you receive it, but only to the extent the original deduction actually reduced your tax under the tax benefit rule. If you took the standard deduction the year you paid the tax, a later refund is not taxable because you got no benefit from the payment. State property tax relief checks that reimburse previously deducted taxes follow the same rule.
