What California Property Tax Is

California property tax is an annual tax on real estate — houses, land, rental properties, and commercial buildings. The county assessor determines the value of your property, and you pay a percentage of that value to your county each year. The money funds local schools, fire departments, roads, and other county services.

Unlike income tax, which is based on what you earn, property tax is based on what your property is worth. If you own a home worth $500,000, you pay tax on that $500,000 value. If you own rental property or commercial real estate, you pay tax on that too. If you do not own property, you do not pay property tax directly — though renters often pay it indirectly through higher rent.

Key Takeaways

  • California property tax is calculated as a percentage of your property's assessed value, set at 1% of the purchase price under Proposition 13.
  • The county assessor determines your property's value, and you can challenge that value if you believe it is wrong.
  • Your property tax bill arrives in two installments each year, usually in November and February, and is due by specific important date or penalties explore.
  • Homeowners over 55 or those with disabilities may transfer their lower tax base to a new home under Proposition 60 or 90.
  • Property tax rates vary by county because each county sets additional taxes on top of the base 1% rate.

How the Tax Rate Is Calculated

California's property tax rate starts at 1% of your property's assessed value. This base rate has been in place since 1978, when voters passed Proposition 13. On top of that 1% base, your county and local districts (schools, fire protection, water districts) can add their own taxes. The total rate you pay depends on where your property is located.

For example, if your home is assessed at $400,000 and your county's total tax rate is 1.25%, you would owe $5,000 per year. A home assessed at $400,000 in a different county with a 1.35% rate would owe $5,400. The difference comes from local add-ons, not the state.

Your property is reassessed at its current market value when you buy it. After that, the assessed value can increase by no more than 2% per year, even if the market value rises much faster. This is also part of Proposition 13. When you sell and a new owner takes over, the property is reassessed at the new purchase price, and the cycle begins again.

Who Determines Your Property's Value

The county assessor is the official who determines what your property is worth for tax purposes. Assessors use recent sales of similar properties, the condition of your building, the size of your lot, and local market trends to set a value. They do not always inspect every property every year — many use computer models based on comparable sales.

You have the right to challenge the assessor's value if you believe it is too high. This is called filing an assessment appeal or Proposition 8 appeal. You can submit evidence such as a recent appraisal, a professional inspection report, or sales prices of nearby homes. The important date to file is usually 30 days after you receive your assessment notice, though some counties allow longer.

If you file an appeal, the county assessor's office or an independent appeals board will review your evidence. If they agree your property was overvalued, they will lower the assessed value, and your tax bill will drop. If they disagree, your original assessment stands. There is no cost to file an appeal.

When and How You Pay Property Tax

Property tax bills in California arrive in two installments. The first bill is usually mailed in November and is due by December 10. The second bill arrives in February and is due by April 10. You can pay online, by mail, or in person at your county tax collector's office.

If you pay late, penalties and interest begin to accrue. Missing the December 10 important date triggers a 10% penalty on the first installment. Missing the April 10 important date triggers another 10% penalty on the second installment. Interest also compounds monthly after the important date passes. If you cannot pay by the due date, contact your county tax collector to discuss payment plans or hardship options.

If your property has a mortgage, your lender may require you to pay property tax through an escrow account. You send money to the lender each month, and the lender pays the tax bill on your behalf when it is due. This protects the lender's investment in your home. If you own your home outright, you pay the tax collector directly.

Proposition 13 and How It Affects Your Tax Bill

Proposition 13, passed in 1978, fundamentally changed how California property tax works. It capped the tax rate at 1% and limited annual increases in assessed value to 2% per year, regardless of how much the market value of your home rises. This means a homeowner who bought a house 30 years ago may pay far less tax than a neighbor who bought an identical house last year.

For example, if you bought a home for $200,000 in 1995, your assessed value today might be around $400,000 (growing at 2% per year). But if your neighbor bought the same home last year for $800,000, their assessed value is $800,000. You pay tax on $400,000; they pay tax on $800,000. Both pay the same 1% rate, but their bills are very different.

Proposition 13 is why property tax in California is often lower than in other states — but it also creates inequality between neighbors. The assessed value resets to current market value only when the property is sold or ownership changes. If you inherit a home, the assessed value may not reset, depending on whether you inherit from a parent or grandparent (Proposition 19 changed some of these rules in 2021).

Tax Breaks and Exemptions for Homeowners

California offers a homeowners' exemption that reduces the assessed value of your primary residence by $7,000. This means if your home's market value is $500,000, the taxable value becomes $493,000. You must file for this exemption with your county assessor — it does not happen automatically. The important date is usually the same as the assessment appeal important date, around 30 days after you receive your assessment notice.

Homeowners over 55, those with disabilities, or those who are severely disabled can transfer their lower tax base to a new home under Proposition 60 or Proposition 90. If you bought your first home 30 years ago and it is now worth $800,000 but your assessed value is only $300,000, you can move to a new home and keep that lower assessed value (up to the market value of the new home). You must file within two years of the purchase of your new home.

Veterans with service-connected disabilities may also receive an exemption. The amount depends on the severity of the disability and ranges from $4,000 to $200,000 of assessed value. You must explore through your county assessor with proof of your disability rating from the Department of Veterans Affairs.

What Happens If You Do Not Pay

If your property tax bill goes unpaid for five years, the county can sell your property at a tax sale to recover the money owed. Before that happens, you receive multiple notices and opportunities to pay. The county will send you a delinquent notice, and you have time to pay the back taxes plus penalties and interest before a sale is scheduled.

If your property goes to a tax sale, a buyer purchases it at auction, and you lose ownership. However, you have a redemption period — usually one year — during which you can reclaim the property by paying the buyer the full amount they paid plus interest. If you do not redeem within that period, the new owner receives the deed.

If you are struggling to pay, contact your county tax collector when ready. Some counties offer payment plans, and you may be able to negotiate a schedule that works for your situation. Waiting until a tax sale is imminent makes your options much more limited.

Frequently Asked Questions

Can I deduct California property tax on my federal income tax return?

Yes, but with limits. Federal law allows you to deduct up to $10,000 per year in state and local taxes combined — that includes property tax, income tax, and sales tax. If your property tax alone exceeds $10,000, you can only deduct $10,000 total. Many California homeowners hit this cap. You must itemize deductions on your federal return rather than taking the standard deduction for this to benefit you.

What if I disagree with my property tax bill amount?

First, check that the bill is for your property and that the assessed value matches your assessment notice. If the bill itself has an error, contact your county tax collector. If you disagree with the assessed value, you must file an assessment appeal with the county assessor — this is separate from disputing the bill amount. The appeal important date is usually 30 days after you receive your assessment notice.

Do I have to pay property tax if I rent out my home?

Yes. Rental properties are taxed the same way as owner-occupied homes — at 1% of assessed value plus local add-ons. The assessed value is based on the market value of the property, not the rent you collect. You pay property tax whether or not you have tenants or whether the property generates income.

What happens to property tax when I inherit a home?

It depends on your relationship to the person who left you the home. If you inherit from a parent or grandparent, Proposition 19 (passed in 2021) may allow the property to keep its lower assessed value if you occupy it as your primary residence. If you inherit from someone else or if you do not occupy it as your primary residence, the assessed value resets to current market value. You should consult a tax professional or your county assessor to understand your specific situation.

Can I pay my property tax in installments?

The county tax collector offers two installments per year — December and April — as the standard payment schedule. If you cannot pay by those important date, contact your county tax collector to ask about payment plans. Some counties allow you to spread payments over several months if you demonstrate financial hardship, though interest and penalties may still explore.
