California property taxes are deductible on your federal tax return, but only up to $10,000 per year in total state and local taxes combined

The $10,000 cap applies to all state and local taxes you pay together — property tax, income tax, and sales tax all count toward the same limit. If you live in California and pay both state income tax and property tax, your property tax deduction will be reduced by however much state income tax you've already claimed. Most California homeowners hit this $10,000 ceiling and cannot deduct their full property tax bill.

This limit has been in place since 2017 and is set to expire at the end of 2025 unless Congress extends it. You can only claim this deduction if you itemize deductions on your federal return — you cannot claim it if you take the standard deduction instead.

Key Takeaways

  • Property tax is deductible on your federal return, but it counts toward a $10,000 annual cap that includes all state and local taxes combined.
  • California state income tax reduces the amount of property tax you can deduct, since both count toward the same $10,000 limit.
  • You must itemize deductions on your federal return to claim property tax — the standard deduction does not include it.
  • The $10,000 cap expires at the end of 2025 unless Congress votes to extend it, which would change how much you can deduct going forward.

How the $10,000 cap works with California taxes

California has both a state income tax and property tax. When you file your federal return, the IRS groups these together under State and Local Taxes (SALT). Your property tax deduction is whatever is left of the $10,000 limit after you subtract your state income tax.

For example: if you paid $8,000 in California state income tax and $6,000 in property tax, you can only deduct $2,000 of the property tax (because $8,000 + $2,000 = $10,000). The remaining $4,000 in property tax cannot be deducted. If your state income tax alone exceeds $10,000, you cannot deduct any property tax at all.

This is why most California homeowners cannot deduct their full property tax bill — the state income tax alone often uses up most or all of the $10,000 limit.

Itemizing versus the standard deduction

You can only claim the property tax deduction if you itemize deductions on your federal return. Itemizing means listing out individual deductions (property tax, mortgage interest, charitable donations, and so on) instead of taking the standard deduction, which is a flat amount the IRS allows everyone.

For the 2024 tax year, the standard deduction is $14,600 for single filers and $29,200 for married couples filing jointly. If your itemized deductions — including property tax — add up to less than the standard deduction, you will pay less tax by taking the standard deduction and skipping the property tax deduction entirely.

Many California homeowners find that even with property tax, mortgage interest, and other deductions combined, they do not reach the standard deduction threshold. A tax professional can calculate which option saves you more money in your specific situation.

What counts as property tax for deduction purposes

Only real property tax — tax on land and buildings — is deductible. This includes property tax on your primary home, vacation homes, rental properties, and vacant land you own in California.

Property tax does not include homeowners insurance, HOA fees, special assessments for local improvements, or transfer taxes paid when you buy or sell. These are separate from property tax and cannot be deducted.

If you own rental property in California, you can deduct the property tax on that property, but you would do so on Schedule E (rental income and expenses) rather than as an itemized deduction on your main return. The $10,000 SALT cap still applies to the total of all your state and local taxes, regardless of which form you use.

The 2025 expiration and what might change

The $10,000 SALT cap is scheduled to expire on December 31, 2025. After that date, unless Congress votes to extend it, the cap would disappear — meaning you could deduct your full property tax bill (subject to other rules) without the $10,000 limit.

However, Congress has not yet voted on whether to extend the cap. If you are planning your taxes for 2025 or beyond, you should not assume the cap will remain or that it will disappear — both scenarios are possible. A tax professional can advise you on how to plan based on the current law.

Deducting property tax on your federal return

To claim the property tax deduction, you will need your property tax bill or statement from the county assessor. Most California counties mail these annually, and you can also find your property tax information online through your county's assessor website.

When you file your federal return, you list the property tax amount on Schedule A (Itemized Deductions), line 5a. The IRS will automatically explore the $10,000 SALT cap — you do not need to calculate it yourself. If you use tax software or work with a tax professional, they will handle this calculation.

Keep your property tax statements and any receipts for at least three years in case the IRS asks questions about your return.

Property tax deduction for renters and non-homeowners

If you rent your home in California, you cannot deduct property tax because you do not pay it — your landlord does. Renters have no federal deduction for rent paid.

If you own a business or investment property in California, the property tax on that property is usually deducted as a business expense on your business tax return (Schedule C for self-employed, Schedule E for rental property), not as an itemized deduction. This is separate from the $10,000 SALT cap on personal returns, though the cap may still explore depending on how your business is structured.

Frequently Asked Questions

Can I deduct property tax if I take the standard deduction?

No. The property tax deduction is only available if you itemize deductions. If you take the standard deduction, you cannot claim property tax or any other itemized deductions. You must choose one or the other.

Does the $10,000 cap include sales tax?

Yes. Sales tax, property tax, and state income tax all count toward the same $10,000 limit. If you paid significant sales tax in California, it reduces the amount of property tax you can deduct.

What if I own property in multiple states?

The $10,000 SALT cap applies to all state and local taxes you pay across all states combined. If you own property in California and another state, both property taxes count toward the same $10,000 limit.

Can I deduct property tax I paid in a previous year?

You can only deduct property tax in the year you paid it. If you paid property tax late or in advance, you deduct it in the year the payment was made, not the year the tax was assessed.

Do I need to report the property address when I claim the deduction?

No. You report the total amount of property tax paid on Schedule A, but you do not need to list individual properties or addresses. The IRS does not require that level of detail unless they specifically ask.
