How California Property Tax Works

Property tax in California is an annual tax levied on real estate by local governments — primarily counties, municipalities, and school districts. The amount you owe is determined by your property's assessed value multiplied by the local mill rate. The statewide effective rate is approximately 0.71% of market value, placing California 0.39% below the national average of 1.10%.

The effective rate combines all local levies: county tax, municipal tax, school district tax, and any special assessments. Because California has multiple taxing jurisdictions, your actual rate depends heavily on where in the state your property is located. The 0.71% figure is a weighted average across all California counties.

On the median California home valued at $683,000, the typical annual property tax bill is about $4,849 — or roughly $404 per month when paid through a mortgage escrow account.

Who Collects Property Tax in California — and How Rates Are Set

In California, property taxes are assessed and collected at the county level. Each county has an assessor who determines property values and a treasurer (or equivalent office) who collects taxes. The state sets the framework and maximum rates; counties, municipalities, and school districts each add their own levies within those limits.

Mill rates (expressed as dollars of tax per $1,000 of assessed value) are set annually based on local budget needs. A mill rate of 10 equals a 1.0% effective rate. Most jurisdictions reassess properties every one to four years, though some reassess annually. If your home's market value rises faster than neighboring properties, your share of the tax burden can increase even if the mill rate stays the same.

To find your exact rate, contact your California county assessor's office or check your county's official website. Your most recent property tax bill will also show the breakdown of all levies applied to your parcel.

California Property Tax Exemptions and Relief Programs

California's Proposition 13 caps property tax increases at 2% per year and offers a Homestead Exemption of $7,000 off assessed value for owner-occupied homes.

Veterans may qualify for a partial or full exemption depending on disability rating and service history. Agricultural land often receives a preferential assessment based on use-value rather than market value. If you believe your assessment is incorrect, you have the right to appeal — typically within 30 to 90 days of receiving your assessment notice.

To apply for any exemption, contact your county assessor. Most exemptions require an annual or one-time application and proof of eligibility (residency, age, disability documentation, etc.).

Property Tax Calculator California: Prop 19 Transfer Rules and Mello-Roos (2026)

The property tax calculator california above uses the statewide effective rate, but two California-specific rules can dramatically change your real bill: Proposition 19 (effective February 16, 2021) and Mello-Roos special assessments. Prop 19 lets homeowners 55+, severely disabled, or wildfire/disaster victims transfer their old Prop 13 base-year value to a new home statewide up to three times in a lifetime — meaning a 70-year-old Long Beach homeowner moving to San Diego can keep their $200,000 assessed value instead of jumping to current market. Prop 19 also tightened parent-to-child inheritance: the child must use the home as a primary residence, and any market value above $1 million over the parent's assessed value is reassessed at current value. Mello-Roos (Community Facilities District) assessments add $1,500–$5,000/year on top of base property tax in newer developments — verify by looking up your parcel at the California State Board of Equalization property tax site or your county assessor before buying.

California Property Tax by County: LA, San Diego, Orange, San Francisco & Riverside (2026)

California's 0.71% statewide effective rate hides big county-level variation. Los Angeles County averages 0.75% effective (median bill $5,132 on a $684k home). San Diego County runs 0.71% ($5,046 on $711k). Orange County is a lower 0.68% despite pricier homes ($6,215 on $914k). San Francisco lands at 0.65% effective — but the median SF home costs $1.35M, so the average bill is $8,775. Riverside County has the highest rate on this list at 0.83%, driven by Mello-Roos-heavy master-planned communities in Corona, Menifee, and Eastvale — expect $4,150 base plus $1,500–$5,000/year Mello-Roos on top. Real tax = base 1% (per Prop 13) + voter-approved bonds (avg 0.15–0.25%) + parcel taxes + Mello-Roos where applicable. Look up your exact parcel on your county assessor site before closing.

California Property Tax Appeal: When and How to Fight Your 2026 Assessment

If the property tax calculator california result differs significantly from your assessed bill — or your home's market value dropped since last assessment — you can appeal to your county Assessment Appeals Board (AAB). Per the California State Board of Equalization Decline-in-Value (Prop 8) rules, the appeal window is July 2 through September 15 or November 30 (varies by county), and you must show that current market value is BELOW your assessed value. Prop 8 is temporary — the county restores your Prop 13 base once market recovers. In 2026, homeowners who bought at 2022 peak prices in Sacramento, Riverside, and San Bernardino counties (where values dropped 8–15%) are seeing successful appeals lowering annual bills by $800–$2,400. File free at your county assessor site; hire a licensed property tax consultant only for homes over $2M. Bring: 3 comparable recent sales, MLS printouts, or a certified appraisal.

Tips to Manage Your California Property Tax Bill

First, verify your assessment is accurate. Review your property record card at the county assessor's office and check for errors in square footage, bedroom/bathroom count, or lot size. Even small errors can inflate your assessed value and tax bill. If the assessment seems high, look up recent sale prices of comparable homes in your neighborhood and file an appeal if warranted.

Second, apply for every exemption you qualify for. Homestead, senior, veteran, and disability exemptions can reduce your taxable value by thousands of dollars. Third, if your mortgage servicer handles tax payments through escrow, review your escrow statement annually. Servicers sometimes over-estimate and hold excess funds — you may be entitled to a refund. Finally, California property taxes are due in two installments: November 1 (delinquent December 10) and February 1 (delinquent April 10).
