Can I Write Off My Property Taxes? SALT Cap, Escrow, and Rentals

You can claim the property tax deduction on your federal return if you itemize, but only up to the state and local tax (SALT) cap, which is $40,400 for most filers in 2026. Property taxes on rental real estate, business property, and the business-use portion of a home office follow separate rules and aren’t subject to that cap at all. Get the mechanics wrong and you either leave money behind or claim something the IRS won’t allow.

The 2026 SALT Cap

The SALT cap limits the combined deduction for all state and local taxes, including real estate taxes, state and local income taxes, and general sales taxes. The One Big Beautiful Bill Act, signed in July 2025, raised the cap from $10,000 to $40,000 for tax year 2025, with 1% annual increases through 2029.¹ For 2026, the cap is $40,400. Married couples filing separately get $20,200 each.

You can deduct real estate taxes plus either state and local income taxes or general sales taxes, not both. Pick whichever gives you the larger number.² Anything above $40,400 gives you no federal benefit.

High earners face a phase-down. The $40,400 cap starts shrinking when modified adjusted gross income exceeds $505,000 ($252,500 for married filing separately), losing 30 cents for every dollar of income above that threshold. It bottoms out at $10,000 ($5,000 for married filing separately). A single filer at $607,000 or more in 2026 is effectively back to the old $10,000 cap. In 2030, the cap reverts to $10,000 for everyone.

Do You Itemize or Take the Standard Deduction

The property tax deduction only helps 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 individuals filing separately, and $24,150 for heads of household.³

Itemizing only pays off when your total itemized deductions, including property taxes and other SALT items, mortgage interest, and charitable contributions, add up to more than the standard deduction.² If they don’t, your property taxes give you nothing on the federal side, no matter how much you paid. With the cap now at $40,400, more homeowners in high-tax areas will find itemizing worthwhile. Run the numbers both ways.

What Counts as a Deductible Property Tax

Not every line on your property tax bill qualifies. The IRS separates taxes from fees, and the distinction matters.

Real Estate Taxes on Your Home

To qualify, a tax must be levied uniformly at a rate based on the property’s assessed value, and the revenue must fund general government purposes.⁴ Standard ad valorem property taxes that fund schools, roads, and local government meet this test. You can deduct these taxes on your primary home and any secondary residence, such as a vacation property.

You must have a legal ownership interest to claim the deduction. Paying property tax on a relative’s house when you’re not on the deed gets you nothing.

Fees and Special Assessments

Itemized charges for specific services aren’t deductible, even when they appear on the same bill. Flat or usage-based charges for trash, water, sewer, or fire protection don’t count.⁴

Special assessments that fund local improvements adding to your property’s value, such as new sidewalks, street repaving, or sewer lines, are also non-deductible. They add to your cost basis instead, which reduces your taxable gain when you sell.⁵ One exception: if part of a special assessment covers maintenance, repairs, or interest rather than a capital improvement, that portion is deductible.

Vehicles and Other Personal Property

Some states tax vehicles, boats, or other personal property annually. These fall under the SALT cap, but only if the tax is based on value. A fee calculated from weight, model year, or horsepower doesn’t qualify. A percentage of market value does.⁶ If your state combines a value-based tax with a flat fee, only the value-based portion is deductible.

Rental, Business, and Home Office Property

Property taxes on real estate used for business or rental income play by different rules. They’re ordinary expenses deducted against that activity’s income, and the SALT cap doesn’t apply.

Rental Property

For a rental, you deduct the full property tax on Schedule E along with repairs, insurance, and depreciation. The tax reduces rental income directly, which lowers your adjusted gross income. No $40,400 ceiling.⁵

Business Property

Real estate used in an active trade or business goes on Schedule C for sole proprietors or Schedule F for farmers. Fully deductible in the year paid, no SALT limit.

Home Office

Use part of your home exclusively and regularly for business, and you can allocate a portion of your property taxes to that use, based on the percentage of square footage dedicated to the office.⁷ Self-employed filers compute the allocation on Form 8829. The business portion comes off Schedule A entirely and gets claimed as a business expense, free from the cap.¹ The personal-use portion stays on Schedule A and counts against the SALT cap as usual. If you use the simplified home office method ($5 per square foot, up to 300 square feet), you deduct the full property tax on Schedule A instead, with no separate business allocation.

Timing: Buying, Selling, Escrow, and Late Payments

Proration at Closing

When a home changes hands, the deduction is split between buyer and seller by the number of days each owned the property during the tax year.⁵ Who physically wrote the check at closing doesn’t matter. Sell on September 1, and you deduct only January 1 through August 31, even if the buyer paid the full annual bill. Your closing statement shows the split.

Escrow

Most homeowners pay property taxes through an escrow account funded with each mortgage payment. The deduction isn’t triggered by what you send into escrow. You deduct the amount in the year your lender actually pays the taxing authority.⁴ Your Form 1098, which arrives in January, shows the amount disbursed on your behalf during the prior calendar year.

Delinquent Taxes

Catching up on your own back taxes? You deduct those payments in the year you make them. Cash-basis taxpayers recognize the expense when the money leaves your account.

A prior owner’s delinquent taxes work differently. If you agreed at closing to pay the seller’s unpaid taxes, those payments aren’t deductible. They get added to your cost basis in the property.⁴

Cutting the Bill Before It Hits Your Return

Your deduction only reflects what you actually owe, so reducing the underlying bill saves money whether or not you itemize. Two tools stand out.

Most states offer a homestead exemption that lowers the taxable assessed value of your primary residence. The amount varies widely, from a few thousand dollars off the assessment to well over $100,000 in some states. You usually apply once with your county assessor, and the reduction carries forward. If you’ve owned your home for years without applying, you may be leaving savings on the table.

Assessment appeals are the other underused option. If your assessed value looks high next to recent sales of comparable homes, you can challenge it. Most jurisdictions give homeowners 30 to 45 days after the assessment notice to file. The process typically starts with a written protest to a local review board, filing fees are usually modest, and comparable sales data supports the case. A win cuts your bill for the current year and often future years too.
