California Property Tax Calculator

Figure basis: Official US Census Bureau, American Community Survey 5-year estimates

This California property tax calculator estimates the annual property tax on a home using the state's median effective property tax rate, which the US Census Bureau reports as 0.71% of a home's value. Enter a home value to see the estimated yearly property tax at that median rate. The Census figure is derived from the median real estate taxes paid in California ($4,926) divided by the median home value ($695,400), from the American Community Survey 5-year estimates. Property tax in the United States is set locally, not by the state, so your actual rate depends on your county, city, school district and any special districts, and on how your property is assessed. Two homes of the same value in different counties of California can have noticeably different bills. Use this as a sound statewide benchmark, then check your county assessor for your property's assessed value and the exact local millage rate, plus any homestead or senior exemptions you qualify for. The median real estate taxes and median home value here are official Census figures; the effective rate is the simple, disclosed ratio of the two.

California's median effective property tax rate is 0.71% of home value (Census: median tax $4,926 on a median home worth $695,400). On a $400,000 home that is about $2,840 a year.

How California property tax is estimated

estimated annual property tax = home value x effective rate / 100
California median effective rate = median real estate taxes / median home value x 100
= $4,926 / $695,400 x 100 = 0.71%

Property tax is levied by local governments, so your exact rate is set by your county and municipality, not the state. The median rate above is a benchmark; check your county assessor for the assessed value and local millage that apply to your home.

Proposition 13 hides California's true rate

California's median effective property tax rate, near 0.70% of home value, sits below the national average, which surprises anyone who knows the state for its high home prices. The explanation is Proposition 13, passed by voters in 1978. It fixes the base tax at 1% of a property's assessed value and caps the annual growth in that assessed value at 2%, no matter how fast the market climbs. Assessed value only resets to the current market price when the home is sold or substantially rebuilt.

That design makes any statewide median a weak guide for one house. A neighbor who bought in 1998 is taxed on a value frozen near the old purchase price plus 2% a year, while the buyer of an identical home in 2025 is assessed at today's full market value. The gap between the two bills can run into thousands of dollars. So if you just bought, do not lean on the 0.70% figure: base your estimate on the price you actually paid, then expect the real rate to clear the 1% floor once voter-approved school and infrastructure bonds and any Mello-Roos special assessments are added, often landing between 1.0% and 1.25%.

One more California wrinkle: Proposition 19, effective in 2021, narrowed the old parent-to-child exclusion, so an inherited home that is not the heir's primary residence is now usually reassessed to market value. Before you rely on a low inherited-property rate, check the county assessor for the current assessed value and the exact voter-approved rates on your tax bill.

Why is California's property tax different from my neighbour's?

Property tax is local, not statewide. Rates and assessment practices vary by county, city and school district, and exemptions (such as homestead exemptions) differ. The 0.71% here is the California statewide median effective rate from the Census; individual bills vary above and below it.
