California's base property tax rate is 1% of assessed value, but your actual bill includes voter-approved local taxes

California's statewide property tax rate is 1% of a property's assessed value. This is set by state law and applies everywhere in the state. However, your total property tax bill is almost always higher than 1% because counties, cities, school districts, and special districts add their own taxes on top of the base rate. These additional taxes are called voter-approved bonds and assessments, and they vary significantly depending on where your property is located.

The 1% base rate was established by Proposition 13 in 1978. Before that, property taxes were much higher and reassessed frequently. Proposition 13 capped the rate at 1% and limited how often properties could be reassessed for tax purposes. This is why California's base rate is lower than most other states, but it also means local governments rely heavily on those additional voter-approved taxes to fund schools, infrastructure, and services.

Key Takeaways

  • California's statewide property tax rate is 1% of assessed value, but your actual bill includes additional local taxes that vary by location.
  • Counties, cities, school districts, and special districts each add their own voter-approved taxes on top of the 1% base rate.
  • Your total effective tax rate typically ranges from 0.76% to 1.5% or higher depending on where the property is located and what bonds or assessments are in place.
  • Properties are reassessed when sold, but existing owners' assessments increase by no more than 2% per year under Proposition 13.
  • You can find your specific property tax rate and bill amount on your county assessor's website or your annual tax bill.

How assessed value is determined and when it changes

Your property tax bill is calculated by multiplying your property's assessed value by the tax rate. The assessed value is not the same as the market value or what you paid for the property. When you buy a property, the county assessor sets the assessed value at the purchase price (or the market value if higher). From that point forward, the assessed value can increase by no more than 2% per year, even if the property's market value rises much faster.

The assessed value resets to current market value only when the property is sold or when certain ownership changes occur. This is why two identical houses on the same street can have very different property tax bills—the one that sold recently will have a higher assessed value than the one owned for decades. When you sell, expect your assessed value to jump to the new purchase price, which will increase your property taxes significantly.

Some properties are partially or fully exempt from property taxes. These include owner-occupied homes (which receive a homeowner's exemption of $7,000 off the assessed value), agricultural land, churches, and government-owned property. If you own your home as your primary residence, you should automatically receive the homeowner's exemption, but you may need to file a form with your county assessor to claim it.

Local taxes and bonds that add to your bill

After the 1% base rate is applied, your county, city, school district, and special districts add their own tax rates. These are called overlapping tax rates or voter-approved assessments. A school district might add 0.5%, a city might add 0.1%, and a county flood control district might add 0.05%. These amounts vary widely by location and change when voters approve new bonds or assessments.

School districts typically make up the largest portion of the additional taxes. California schools are heavily funded by property taxes, so school district rates are often 0.4% to 0.8% of assessed value depending on the district. Cities and counties add smaller amounts for general operations, and special districts (water, fire, flood control, library) add their own rates for specific services.

When you receive your property tax bill, it will show the 1% base rate plus each overlapping rate separately. The total of all these rates is your effective tax rate. In some areas this total is around 0.76% to 0.85%, while in others it can exceed 1.5%. The difference depends entirely on which districts serve your property and what voter-approved taxes are in place.

Finding your specific property tax rate

Your county assessor's office maintains records of every property's assessed value and tax rate. You can visit your county assessor's website and search by address or parcel number to see your assessed value and the breakdown of all taxes applied to your property. Most county websites allow free online searches without registration.

Your annual property tax bill, called a property tax statement or tax bill, shows your assessed value, the tax rate, and the total amount due. This bill is mailed to the property owner and the mortgage lender (if there is one). The bill also shows the due date and payment instructions. If you do not receive a bill, contact your county tax collector's office.

If you want to know the tax rate before buying a property, ask the seller's agent or the county assessor for a preliminary assessment. Keep in mind that the assessed value will change to the purchase price once you buy, so your taxes will increase. You can estimate your new tax bill by multiplying the purchase price by the effective tax rate in that area.

How Proposition 13 affects your taxes over time

Proposition 13 limits how much your assessed value can increase each year. Once your property is assessed, the value can rise by a maximum of 2% per year, regardless of how much the property's market value actually increases. This means if you buy a house for $500,000, your assessed value starts at $500,000. The next year it can only go up to $510,000 (2% increase), then $520,200, and so on—even if the market value jumps to $700,000.

This protection benefits long-term homeowners because their property taxes stay relatively stable. However, it also means that when you sell and buy a new property, your assessed value resets to the new purchase price, and your taxes jump accordingly. A homeowner who has owned their house for 20 years may pay significantly less in property taxes than a neighbor who just bought an identical house next door.

Proposition 13 also requires a two-thirds voter approval for any new taxes or increases to existing tax rates. This makes it difficult for local governments to raise revenue, which is why many rely on special assessments (which sometimes require only a majority vote) or state funding.

Property tax rates by county and region

Property tax rates vary across California because each county, city, and school district sets its own rates. There is no single "California rate" beyond the 1% base. Some areas have effective rates around 0.76% (mostly rural counties with lower local tax burdens), while others exceed 1.25% or 1.5% (urban areas with high school funding needs and city services).

The Bay Area, Los Angeles County, and San Diego County tend to have higher effective rates because of dense populations, high school funding needs, and multiple overlapping districts. Rural counties often have lower rates because they have fewer districts and lower service demands. However, this is a generalization—the only way to know your specific rate is to check your county assessor's records or your tax bill.

If you are considering buying property in California, research the effective tax rate in the specific area and school district. The difference between a 0.8% rate and a 1.3% rate on a $600,000 home is $3,000 per year. Over a 30-year mortgage, that adds up significantly.

Frequently Asked Questions

Is California's property tax rate the same everywhere in the state?

No. The statewide base rate is 1%, but every county, city, school district, and special district adds its own taxes on top of that. Your total effective rate depends on where your property is located. Two properties in different counties can have very different total tax rates even though they have the same market value.

What happens to my property taxes when I sell my house?

When you sell, the new owner's assessed value resets to the purchase price. Your taxes do not change until the sale closes and the new owner takes title. After that, the new owner's assessed value can increase by only 2% per year under Proposition 13, unless the property is sold again.

Can I reduce my property tax bill?

If you own your home as your primary residence, make sure you have claimed the homeowner's exemption, which reduces your assessed value by $7,000. You can also file a Proposition 8 appeal if you believe your assessed value is higher than the property's market value. Contact your county assessor's office for details on how to file.

Why is my property tax bill higher than my neighbor's if our houses are similar?

The most common reason is that one house was purchased more recently than the other. Under Proposition 13, assessed values increase by only 2% per year. If your neighbor bought 15 years ago and you just bought, your assessed value is much higher, so your taxes are higher. Once you own the property for a while, the gap will narrow slightly each year.

How do I find out what my property taxes will be before I buy?

Contact the county assessor's office in the area where you are buying and ask for the effective tax rate. Multiply the purchase price by that rate to estimate your annual bill. Keep in mind this is an estimate—your actual bill may vary slightly depending on which specific districts serve the property and what voter-approved assessments are in place.
