Here is a breakdown of property tax rates across California major counties, how the assessment system works, and what you can do if you think you are paying too much.
How California Property Taxes Are Calculated
Your property tax bill is determined by two factors: your assessed value and your tax rate. In California, property is assessed at Proposition 13 limits: assessed at 1975 value + max 2% annual increase, or purchase price + max 2% annual increase. The tax rate (often expressed as a mill rate or dollars per hundred of assessed value) is set by your county, city, school district, and other local taxing authorities.
Your total tax bill = assessed value x combined tax rate from all overlapping taxing districts.
California Property Tax Rates by County
| County | Effective Rate | Median Home Value | Median Annual Tax |
|---|---|---|---|
| Los Angeles County | 0.70% | $750,000 | $5,250 |
| San Diego County | 0.73% | $785,000 | $5,731 |
| Orange County | 0.68% | $900,000 | $6,120 |
| Santa Clara County | 0.67% | $1,350,000 | $9,045 |
| San Francisco County | 0.63% | $1,400,000 | $8,820 |
| Alameda County | 0.72% | $950,000 | $6,840 |
| Riverside County | 0.91% | $530,000 | $4,823 |
| Sacramento County | 0.80% | $480,000 | $3,840 |
Rates shown are effective rates (total taxes paid as a percentage of home market value). Your nominal tax rate from the county may look different because it is applied to assessed value, not market value.
Why Rates Vary So Much
School Districts
School district taxes typically make up 50-70% of your total property tax bill. High-performing or high-spending school districts drive higher tax rates. Two homes in the same county but different school districts can have very different tax bills.
Local Government Services
Cities and counties with more services (police, fire, parks, libraries, public transit) fund them through property taxes. Urban areas tend to have higher rates than rural areas for this reason.
Special Districts
Hospital districts, water districts, fire protection districts, and other special purpose districts add their own levies on top of city, county, and school taxes. You may be in multiple special districts without realizing it.
Property Values
Areas with higher property values can generate the same revenue at a lower tax rate. Wealthy suburban counties often have lower rates than urban or rural areas because their tax base is larger.
How to Check Your Actual Rate
Your effective tax rate is the amount you actually pay divided by your home's market value. To calculate yours:
- Find your total annual property tax payment on your tax bill
- Divide by your home's estimated market value (not assessed value)
- Multiply by 100 to get a percentage
If your effective rate is significantly higher than the county average shown above, your assessment may be too high. Consider filing an appeal.
How to Lower Your California Property Tax Rate Impact
You cannot change the tax rate itself since that is set by elected officials and taxing authorities. But you can reduce your assessed value, which directly lowers your bill. There are two main approaches:
1. Claim Every Exemption You Qualify For
Exemptions reduce your taxable value. Most California homeowners qualify for at least a homestead exemption. Seniors, veterans, and disabled homeowners often qualify for additional exemptions. See our guide to lowering California property taxes for every available method.
2. Appeal Your Assessed Value
If your home's assessed value is higher than its actual market value, or higher than comparable homes in your area, you can appeal. A successful appeal directly reduces your tax bill. See our California property tax appeal guide for step-by-step instructions.

Your Next Steps
Take action on your California property taxes this week:
- Pull your property record card. Request it from your county assessor's office or check their website. Compare every detail to your actual property and flag anything incorrect.
- Check recent neighborhood sales. Find 3 to 5 homes similar to yours that sold in the past 12 months. If they sold for less than your assessed value, you have the basis for a strong appeal.
- File for unclaimed exemptions. Many California homeowners qualify for exemptions they have never applied for. Seniors, veterans, and disabled homeowners should check eligibility immediately.
- Mark your appeal deadline. Find the date on your assessment notice and set a calendar reminder for two weeks before. A missed deadline means another full year of overpaying.
Why Acting Now Matters in California
Every month you delay is money lost. Property taxes are assessed annually, and once the tax year begins, you are locked in at your current assessed value unless you file an appeal. There is no retroactive correction for years when you overpaid but did not challenge the assessment.
In California, the appeal window is limited. Once it closes, you wait a full year for your next opportunity. Homeowners who act promptly after receiving their assessment notice have the best outcomes because they have the most time to gather evidence, review comparable sales, and prepare a clear case.
If you are reading this and your current assessment notice is sitting unopened, go read it now. That single step puts you ahead of the majority of homeowners who never check their assessments at all.
