California's Base Property Tax Rate Is 1%, But Your Actual Rate Depends on Your County

California's statewide property tax rate is 1% of assessed property value. This is the base rate set by state law. However, your total property tax bill is almost always higher because counties and local districts add their own taxes on top of that 1%. The actual rate you pay depends on where your property sits — your county, school district, city, and any special districts that serve your address all layer on additional taxes.

The 1% base rate applies to the assessed value of your property, not its market value. This distinction matters. When you buy a property, the county assessor sets an assessed value based on the purchase price. That assessed value can only increase by up to 2% per year, even if your home's market value climbs much faster. This is called the Proposition 13 cap, and it is why two identical homes on the same street can have very different tax bills if one sold recently and the other sold decades ago.

Your total property tax rate — the 1% plus all local additions — typically ranges from about 0.8% to 1.5% of assessed value, depending on your location. A property assessed at $500,000 in one county might generate a $4,500 annual bill, while the same property in another county could cost $6,500 or more.

How Counties and Local Districts Add to the Base Rate

The 1% state rate is just the beginning. On top of that, your county collects taxes for county services. Your school district adds a rate for schools. Your city adds a rate for city services. If you live in an area served by a water district, fire district, or other special district, each of those adds a rate as well. These all stack together to create your final property tax rate.

The amount each district adds varies widely. A school district in a wealthy area might add 0.3% to your bill, while a school district in a less-funded area might add 0.5% or more. County rates also differ — some counties add 0.15% while others add 0.25% or higher. There is no single "California rate" beyond the 1% base; your actual rate is a sum of decisions made by multiple local bodies.

You can see the breakdown on your property tax bill, which lists each taxing agency and its rate. Your county assessor's office also publishes this information online, usually searchable by address or parcel number. If you are considering buying property in California, checking the total tax rate for that specific address is worth doing before you make an offer.

What Proposition 13 Means for Your Tax Bill Over Time

Proposition 13, passed in 1978, caps how fast your assessed value can rise. Your assessed value can increase by no more than 2% per year, even if your home's market value doubles or triples. The only time your assessed value resets to current market value is when the property sells. This is why long-term owners often pay far less in property tax than newer owners in the same neighborhood.

This cap affects your bill directly. If you bought your home for $400,000 and it is now worth $800,000, your assessed value is still based on that $400,000 purchase price (plus 2% annual increases). You pay 1% of that lower assessed value, not 1% of the current market value. A neighbor who just bought an identical home for $800,000 pays tax on the full $800,000 assessed value. Over time, this difference compounds.

When you sell your property, the new owner's assessed value resets to the sale price. This is sometimes called a "reassessment." The new owner then starts the 2% annual increase cycle from that new, higher base. This is one reason property taxes are often a surprise for new California homeowners — they may not realize they are paying tax on current market value while long-term owners in their neighborhood pay tax on much older purchase prices.

Finding Your Specific Property Tax Rate and Assessed Value

Your property tax bill arrives once or twice per year, depending on your county. It shows your assessed value, the tax rate applied to it, and the total amount due. The bill also breaks down which agencies are collecting taxes — county, school district, city, and special districts. If you have lost your bill or want to check before buying, your county assessor's office maintains searchable records online.

To find your information, go to your county assessor's website and search by address or parcel number. Most counties allow free searches. You will see the assessed value, the property description, and sometimes a breakdown of tax rates. Some counties also show the sale history, which helps you understand why your assessed value is what it is.

If you believe your assessed value is wrong — for example, if the assessor recorded incorrect square footage or missed a major repair that lowered value — you can file a formal appeal. The important date to appeal is usually 30 days after your bill arrives, though some counties allow longer. Contact your county assessor's office for the specific process in your area.

How Property Tax Rates Differ Across California Counties

Total property tax rates vary noticeably from county to county. This variation comes from different local tax rates layered on top of the 1% base. A property in one county might have a total rate of 0.95% (lower than the state base, because some older bonds have been paid off), while the same property in another county might face 1.4% or higher.

Urban counties with higher service demands and older infrastructure often have higher rates. Rural counties sometimes have lower rates, though not always — it depends on local debt, school funding needs, and special district taxes. If you are relocating within California or comparing two properties in different counties, the property tax rate difference can add thousands of dollars per year to your costs.

You can compare rates across counties by checking the assessor websites for each area you are considering. Look at the total tax rate listed on sample properties, or ask the county assessor directly. Real estate agents can also provide this information, though it is worth verifying on the official county site.

Special Assessments and Bonds That Increase Your Bill

Beyond the regular property tax rate, some properties are subject to special assessments or bond taxes. These are additional charges that appear on your bill and are tied to specific projects or services. A special assessment might fund a new school building, a water system upgrade, or a fire station. Bond taxes repay debt issued to pay for past projects.

Special assessments and bonds are not part of the standard rate — they are separate line items on your bill. They can last for 20, 30, or even 40 years, depending on the project. If you buy a property that has an active special assessment, you inherit that obligation. This is why it is important to ask about special assessments when buying property or to check your county assessor's records before making an offer.

Your property tax bill lists all special assessments and bonds separately, so you can see exactly what you are paying for. If you are unsure what a particular charge is, the county assessor or your local tax collector can explain it.

Frequently Asked Questions

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

No. The base rate is 1%, but counties and local districts add their own taxes on top of that. Total rates range from roughly 0.8% to 1.5% of assessed value, depending on your county, school district, city, and any special districts serving your address. You need to check the specific rate for your property's location.

Why do two homes on the same street have different property tax bills?

Proposition 13 caps assessed value increases at 2% per year. A home that sold 20 years ago has a much lower assessed value than an identical home that sold last year, even though they have the same market value. The older owner pays tax on a lower assessed value, while the new owner pays tax on the current purchase price.

Can my property tax bill go down if my home's value drops?

Rarely. Your assessed value can only increase (by up to 2% per year) or reset when the property sells. It does not decrease if the market value falls. The only exception is if you successfully appeal your assessment and prove the assessed value is too high, or if a natural disaster significantly damages the property.

What happens to my property taxes when I buy a home in California?

Your assessed value resets to the purchase price when you buy. You then pay 1% of that assessed value, plus local district taxes, for a total rate of roughly 0.8% to 1.5% depending on location. Your assessed value can only increase 2% per year after that, unless you sell again.

Where can I find my property's assessed value and tax rate?

Your property tax bill shows both. You can also search your county assessor's website by address or parcel number — most counties offer free online searches. The assessor's office can also provide this information by phone or in person.
