California's base property tax rate is 1% of assessed value, but your actual bill includes voter-approved local taxes that vary by county and district
California's statewide property tax rate is set at 1% of a property's assessed value under Proposition 13, passed in 1978. This 1% goes to the county assessor, county treasurer, schools, and other local services. However, your total property tax bill is almost always higher than 1% because counties, cities, school districts, and special districts can add their own taxes on top of the base rate. These additional taxes, called voter-approved bonds and assessments, vary significantly depending on where your property is located.
Your actual property tax rate depends on three things: the 1% statewide rate, the county where your property sits, and which local districts have passed bond measures or special assessments. A property in one California county might pay 1.1% total, while an identical property in another county pays 1.4% or higher. The only way to know your exact rate is to look at your county assessor's website or your property tax bill, which lists every tax component separately.
Key Takeaways
- California's base property tax rate is 1% of assessed value statewide, but most properties pay additional local taxes on top of this amount.
- Counties, cities, school districts, and special districts can add voter-approved taxes and assessments that raise your total rate above 1%.
- Your actual property tax rate varies by location within California, so two similar homes in different areas can have different total tax bills.
- Property values are reassessed when you buy a home or make major improvements, which can significantly change your annual tax bill.
- Your county assessor's website and your annual property tax bill both show the exact rate and all components of your local taxes.
How the 1% base rate works under Proposition 13
Proposition 13, passed by California voters in 1978, capped the statewide property tax rate at 1% of assessed value. This means the state cannot impose a property tax higher than 1%. The assessed value is not the market value of your home — it is the value the county assessor determines for tax purposes, which is often lower than what your home would sell for.
When you buy a property, the county assessor reassesses it at its purchase price (or current market value if higher). After that, the assessed value can increase by no more than 2% per year, even if your home's market value rises much faster. This is why homeowners who have owned their property for many years often pay significantly less in property taxes than newer owners in the same neighborhood. The 1% rate applies to this assessed value, not the current market price.
Local taxes and voter-approved bonds that add to your bill
On top of the 1% base rate, your county and local districts can impose additional property taxes if voters approve them. These typically take the form of bond measures for schools, infrastructure, or public safety, and special assessments for specific services like fire protection or water districts. Each of these is a separate line item on your property tax bill.
For example, your bill might show: 1% base rate (0.76% to county, 0.24% to schools), plus 0.15% for a school bond measure, plus 0.08% for a fire district assessment, plus 0.05% for a water district. Your total rate would be 1.28%. In another county, the same breakdown might total 1.10% or 1.45%, depending on which bond measures and assessments have passed locally.
These additional taxes are not optional — they are legally imposed once voters approve them. However, they are temporary. Most bond measures last 20 to 30 years and then expire unless voters renew them. Special assessments also have set end dates. Your property tax bill will show when each tax component expires.
How county assessors determine your property's assessed value
The county assessor's job is to determine the assessed value of every property in the county. This value is used to calculate your 1% base tax and is the foundation for all other local taxes. Assessors use several methods: recent sales of similar properties, income the property generates (for rental properties), or the cost to replace the building.
When you purchase a property, the assessor typically reassesses it at the purchase price within a few months. If you make major improvements — adding a room, replacing the roof, or installing solar panels — the assessor may reassess the property and increase the assessed value. Minor repairs and maintenance do not trigger reassessment. After the initial assessment, the value can rise by a maximum of 2% per year, regardless of market conditions, until the property is sold again.
You have the right to appeal your assessed value if you believe it is incorrect. Most counties have a formal appeal process, and you can file a Proposition 15 appeal (based on market value) or a Proposition 8 appeal (based on decline in value). The important date to file is usually 30 days after you receive your assessment notice, though some counties allow longer periods. Your county assessor's office can provide the specific timeline and forms.
Variation in property tax rates across California counties
Because local districts can add their own taxes, property tax rates vary across California. The statewide base is always 1%, but total rates typically range from about 0.76% to 1.5% depending on the county and which bond measures are in effect. Some counties with many voter-approved bonds may exceed 1.5%.
Counties with higher rates often have more recent school bond measures, larger fire districts, or special water or flood control assessments. Rural counties may have lower rates if fewer bond measures have passed. Urban areas with newer infrastructure bonds tend to have higher rates. This variation is one reason property tax bills can differ significantly between similar homes in different parts of California.
You can find your county's average property tax rate on the county assessor's website, though this is only an average — your individual rate depends on which specific districts your property is in. The most accurate way to learn your rate is to look at a recent property tax bill or contact your county assessor directly.
What happens to your property tax bill when you buy or improve your home
When you purchase a property, expect your property tax bill to increase significantly if the previous owner had owned it for many years. The county assessor will reassess the property at the purchase price, which is usually much higher than the previous assessed value. Your new bill will reflect the 1% base rate plus all local taxes, applied to this new, higher assessed value.
If you make major improvements to your home, the assessor may reassess the property and increase the assessed value accordingly. However, not all improvements trigger reassessment. The assessor typically reassesses only when the improvement adds value to the property itself — such as adding square footage, replacing a roof, or installing a pool. Painting, landscaping, or replacing interior fixtures usually does not trigger reassessment. If you are unsure whether a planned improvement will affect your assessment, contact your county assessor before starting work.
How to find your specific property tax rate
Your annual property tax bill is the most reliable source for your exact rate. It lists every tax component — the 1% base rate, school bonds, fire assessments, water district taxes, and any other local taxes — along with the percentage each represents. The bill also shows your assessed value and the total amount due.
If you do not have a recent bill, you can visit your county assessor's website. Most counties allow you to search for your property by address or parcel number and view the assessed value and tax rate information online. Some counties charge a small fee for this service; others provide it free. You can also call your county assessor's office directly and ask for your property's assessed value and total tax rate.
Frequently Asked Questions
Can my property taxes increase more than 2% per year?
Your assessed value can increase by no more than 2% per year under Proposition 13, but your total tax bill can increase more if new voter-approved bonds or assessments take effect. For example, if a school bond measure passes, your bill will jump by the amount of that new tax, even though your assessed value only rose 2%.
What is the difference between assessed value and market value?
Assessed value is what the county assessor determines your property is worth for tax purposes. Market value is what your home would sell for today. Assessed value is often lower than market value, especially if you have owned your home for many years. The 1% property tax rate applies to assessed value, not market value.
Do I have to pay property taxes if I own my home outright?
Yes. Property taxes are owed by the property owner, whether the home is paid off or financed. If you have a mortgage, your lender typically collects property taxes as part of your monthly payment and pays them on your behalf. If you own the home outright, you receive a bill directly from the county and must pay it yourself.
What happens if I do not pay my property taxes?
If property taxes are not paid by the due date, penalties and interest accrue. The county can place a lien on your property and eventually foreclose and sell it to recover the unpaid taxes. If you are having trouble paying, contact your county tax collector about payment plans or hardship options.
Can I deduct California property taxes on my federal income tax return?
You may be able to deduct state and local property taxes (including California property taxes) on your federal return, but the total deduction for all state and local taxes combined is capped at $10,000 per year. Consult a tax professional to determine whether you can deduct your California property taxes and how much you can claim.
