Can You Deduct Property Taxes? SALT Cap, Itemizing, and AMT

Yes, you can deduct property taxes on your federal return, but the rules split sharply depending on how the property is used. Taxes on a personal home or vacation property are deductible only if you itemize, and they share a combined state and local tax (SALT) cap of $40,400 for tax year 2026.¹ Property taxes on rental or business real estate are fully deductible with no cap and no itemizing required.

The SALT Cap and What It Covers

The SALT cap limits the total you can deduct on Schedule A for all state and local taxes combined: property taxes, state income taxes (or state sales taxes, if you elect those instead), and local taxes. For 2026, that ceiling is $40,400, up sharply from the $10,000 limit that applied from 2018 through 2024.¹ Married filing separately is capped at $20,200.

Because everything sits in one bucket, the mix matters. If state income tax already consumes $30,000 of your $40,400, you have only $10,400 of room left for property taxes, no matter how large the bill.

Phase-Out for Higher Incomes

The full cap does not survive at every income level. When modified adjusted gross income exceeds $505,000 ($252,500 for married filing separately), the cap shrinks by 30 cents for each dollar over that threshold.² Around $606,000 of MAGI, the cap bottoms out at $10,000 ($5,000 for married filing separately).

How Long the $40,400 Cap Lasts

The One Big Beautiful Bill Act set the higher SALT cap for tax years 2025 through 2029, with the dollar amount growing 1% annually. After 2029, the cap reverts unless Congress acts. The $40,400 figure applies specifically to 2026 returns.¹

You Have to Itemize

Property taxes on a personal residence show up only if you itemize on Schedule A. Take the standard deduction and the property tax deduction disappears entirely.³ For 2026, the standard deduction is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household.¹

Itemizing pays only when your combined deductions, including mortgage interest, charitable giving, and SALT, beat those figures. The much larger SALT cap for 2026 pushes more homeowners over that line than in recent years, especially in states with meaningful income and property tax bills. If you are close, run the return both ways before deciding.

Which Property Taxes Actually Qualify

A charge is deductible only if it is assessed uniformly at a like rate on all property in the jurisdiction and funds general government purposes.⁴ Standard real estate taxes on your primary home and any vacation homes meet that test.

Some personal property taxes qualify too, but only when the tax is based on the item’s value and charged annually. A vehicle registration fee calculated as a percentage of the car’s market value is the common example. A flat fee that ignores value does not count.

Charges That Look Like Property Taxes But Aren’t Deductible

Assessments for local improvements such as new sidewalks, sewers, or street work. These get added to your home’s cost basis, which can reduce capital gains later.⁴
Service fees for trash pickup, water, and similar utilities, even when billed alongside property taxes.
Transfer taxes paid at purchase or sale. These are closing costs that adjust basis.
Foreign real property taxes on a personal residence. The deduction was eliminated starting in 2018 and remains barred through 2029. Foreign property taxes on rental or business property are still fully deductible.²

Co-op shareholders do not get a direct tax bill; instead, you deduct your proportionate share of the corporation’s real estate taxes, which the co-op reports to you each year.⁵ That amount goes on Schedule A under the same SALT cap.

Rental, Business, and Mixed-Use Property

Property taxes on real estate that produces income are ordinary business expenses. They reduce your income before the SALT cap ever enters the picture.⁶ A landlord deducts the full property tax for a rental on Schedule E. A sole proprietor with an office building deducts it on Schedule C. No cap, no itemizing.

Mixed use is where a lot of value hides. Own a four-unit building and live in one unit? Roughly 75% of the property tax is a rental expense on Schedule E, uncapped, and only the remaining 25% lands on Schedule A under the SALT limit.

Home Office

If you use part of your home exclusively and regularly for business, you can allocate a share of the property tax to the business side. Under the regular method, you divide by the square-footage percentage, put the business share on Schedule C outside the SALT cap, and leave the personal share on Schedule A.⁷ The simplified method ($5 per square foot, up to 300 square feet) is easier but keeps all of the property tax on Schedule A under the cap. For homeowners with hefty property tax bills, the regular method usually gives up more of the tax to the uncapped side.

When You Can Claim It

Most individuals use the cash method and deduct property taxes in the year they are actually paid, not when the bill is assessed or arrives. A few situations complicate that.

Escrow

If your mortgage servicer pays property taxes from escrow, the deduction lines up with when the lender pays the county, not when you make monthly deposits. Box 10 of Form 1098 reports the total disbursed during the year.⁸ Cross-check that figure against county receipts.

Prepayments

You can pay a property tax bill before the due date and deduct it, but only if the tax has actually been assessed. Sending money for a future, unassessed tax is a deposit, not a deductible payment. That trips up taxpayers trying to push next year’s taxes into December.

Buying or Selling Mid-Year

When a property changes hands during the year, the IRS splits the annual tax between buyer and seller by days of ownership, regardless of who wrote the check.⁴ If a buyer paid more than their allocated share at closing, the excess is not deductible; it adds to cost basis. If the buyer also covered the seller’s delinquent taxes as part of the deal, those back taxes are not deductible either. They become part of the purchase price.

The closing disclosure shows the allocation. Keep it with your tax records.

The AMT Can Wipe It Out

Taxpayers subject to the alternative minimum tax lose the property tax deduction entirely. On the AMT calculation, all SALT deductions get added back to income. The $40,400 cap on the regular side offers no protection. For 2026, the AMT exemption is $90,100 for single filers and $140,200 for joint filers, with phase-outs starting at $500,000 and $1,000,000.¹

Someone in a high-tax state might deduct $40,000 in SALT on the regular return and watch the AMT claw most of it back. Tax software runs the calculation automatically, but the smaller refund still surprises people. Near AMT territory, the deduction’s real value can be much less than its face amount.

Refunds and Rebates

Deducted property taxes in a prior year and then received a refund from a successful assessment appeal, retroactive rate reduction, or relief program? Under the tax benefit rule, that refund is taxable income in the year received, but only to the extent the original deduction actually reduced your tax.⁹

Refund arrives in the same year you paid the tax? Just reduce that year’s deduction by the refund amount. No separate income item.⁴

Where to Report It

Personal residence or vacation home: Schedule A, Line 5b for real estate taxes and Line 5c for qualifying personal property taxes; the SALT-capped total flows to Line 5e.
Rental property: Schedule E, as an expense against rental income.⁶
Business property: Schedule C, as an operating expense.⁶

Keep the Form 1098 from your servicer, direct receipts from the county, and any closing statements from purchases or sales that year.⁴ Nothing gets attached to the return, but you need it if the IRS asks.
