  • About This Answer

    To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county.

California Property Taxes

Photo credit: ©iStock.com/DustyPixe

Property taxes in California are limited by Proposition 13, a law approved by California voters in 1978. The law has two important features. First, it limits general property taxes (not including those collected for special purposes) to 1% of a property’s market value. And secondly, it restricts increases in assessed value to 2% per year. Those two rules combine to keep California’s overall property taxes below the national average. The average effective property tax rate in California is 0.79%, compared with a national average of 1.19%

How Property Taxes in California Work

California property taxes are based on the purchase price of the property. When you buy a home, the assessed value is equal to the purchase price. From there, the assessed value increases every year by the rate of inflation (change in the California Consumer Price Index), with a cap on increases of 2%.

This means that, for homeowners who have been in their house a long time, assessed value is often lower than market value. The same is true of homeowners in areas that have experienced rapid price growth such as San Francisco and San Jose in recent years.

Homeowners in California can claim a $7,000 exemption on their primary residence. This reduces the assessed value by $7,000, saving you at least $70 per year. You only need to claim this exemption once and it’s important to do so shortly after you buy – the due date is Feb. 15.

California Property Tax Rates

Property taxes are applied to those assessed values. Each county collects a general property tax equal to 1% of assessed value. That general tax is the single largest tax, but there are other smaller taxes that vary by city and district.

Voter-approved taxes for specific projects or purposes are common, as are “Mello-Roos” taxes. Mello-Roos taxes are voted on by property owners and are used to support special districts that finance services, public works or other improvements.

A good rule of thumb for California home buyers who are trying to estimate what their property taxes will be is purchase price x 1.25%. This incorporates the base rate of 1% and additional local taxes, which are usually about 0.25%.

The table below shows effective property tax rates, as well as average annual property tax payments and average home value, for each county in California. Assessed value is often lower than market value so effective tax rates (taxes paid as a percentage of market value) in California are typically lower than 1%, even though nominal tax rates are always at least 1%.

Los Angeles County

San Diego County

The average effective property tax rate in San Diego County is 0.76%, significantly lower than the national average. However, because assessed values rise to the purchase price when a home is sold, new homeowners can expect to pay higher rates than that.

Rates homeowners can expect to pay vary by city. In the city of San Diego, property tax rates are 1.16967%. In Chula Vista, which sits to the south of San Diego, the rate is lower at 1.12573%. In Oceanside, the rate is 1.11393%, not very much higher than the baseline rate of 1%.

Orange County

The median annual property tax homeowners pay in southern California’s Orange County is $4,027. That is the eighth highest amount in the state and $1,830 more than the national median.

Riverside County

The average effective property tax rate in Riverside County is 1.00%, second highest in the state. While that is the rate a typical homeowner in the county pays, it is not necessarily what a new homeowner will pay. Since assessed values rise (or fall) to equal purchase price when a home is bought or sold, homeowners in Riverside County can expect to pay 1% plus the sum of local voter-approved rates. In the city of Riverside, total property tax rates range from about 1.08% to 1.20%.

San Bernardino County

San Bernardino County is the fifth largest county in California by population and the largest county in both the state and the country by area. It has a land area of 20,057 square miles, making it slightly larger than Costa Rica. The average effective property tax rate in San Bernardino County is 0.86%, 17th highest in the state.

Santa Clara County

The median home value in Santa Clara County is among the highest in the nation, at $615,200 in 2016. That ranks fourth in California and fifth in the U.S. Because of those high home values, annual property tax bills for homeowners in Santa Clara County are quite high, despite actual rates near the state average. The median annual property tax in Santa Clara County is $5,800, second highest in the state.

Alameda County

Situated on the eastern shore of the San Francisco Bay, Alameda County contains the cities of Oakland, Berkeley and Fremont (among others). The total tax rate in Oakland is 1.3486%, according to 2014 and 2015 data. The rate in Berkeley is 1.2136%. The rate in Fremont is 1.1641%. Those rates apply to assessed value, which is equal to the sales price of recently purchased homes but is otherwise generally lower than actual value.

Sacramento County

Sacramento County is located in northern California and has a population of about 1.6 million. It is also home to the state capital. The county’s average effective property tax rate is 0.88%, 12th highest in the state. At that rate, the total property tax on a home worth $200,000 would be $1,760. New homeowners in Sacramento County can expect to pay higher rates than that however, between 1% and 1.5% depending on where in the county they live.

Contra Costa County

The median property tax paid by homeowners in the Bay Area’s Contra Costa County is $4,224 per year, sixth highest in California. That is nearly double the national median property tax payment.

Fresno County

According to the U.S. Census Bureau, the median home value in Fresno County is $204,900, 50% lower than the state median. That means that, while property tax rates in Fresno County are similar to those in the rest of the state, property taxes paid in dollar terms are far lower.

Rank County Property Tax Rate School Rating Crimes Per 100k People


Our study aims to find the places in the United States where people are getting the most for their property tax dollars. To do this we looked at school rankings, crime rates and property taxes for every county.

As a way to measure the quality of schools, we analyzed the math and reading/language arts proficiencies for every school district in the country. We created an average score for each district by looking at the scores for every school in that district, weighting it to account for the number of students in each school. Within each state, we assigned every county a score between 1 and 10 (with 10 being the best) based on the average scores of the districts in each county.

For each county, we calculated the violent and property crimes per 100,000 residents.

Using the school and crime numbers, we calculated a community score. This is the ratio of the school rank to the combined crime rate per 100,000 residents.

We used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.

Finally, we calculated a tax value by creating a ratio of the community score to the per capita property tax paid. This shows us the counties in the country where people are getting the most bang for their buck, or where their property tax dollars are going the furthest.
