🇺🇸 California Property Tax Calculator
Estimate California property tax from your assessed home value and local effective rate. California property tax is uniquely governed by Proposition 13, which caps the base rate at 1% of assessed value and limits annual assessment increases to just 2%. With local bonds and levies, most California homeowners pay an effective rate between 0.65% and 1.1%, making it lower than many other states despite high home prices.

Formule
Multiply your assessed value (not market value) by the effective annual tax rate. In California, assessed value is typically the purchase price plus up to 2% annual increases under Prop 13. Divide the annual tax by 12 for a monthly estimate. Rates typically range from 0.65% to 1.1% depending on county, city bonds, and local levies.
Questions Frequentes
How does Proposition 13 affect property tax?
Prop 13 (1978) caps the base property tax rate at 1% of assessed value at time of purchase. Annual increases in assessed value are limited to 2%, regardless of actual market appreciation. This means long-term homeowners pay much less than recent buyers for comparable properties.
What is the effective property tax rate in California?
Typically 1.0-1.25% of assessed value (not market value). The base 1% rate plus local bonds and assessments brings most areas to 1.1-1.25%. New developments with Mello-Roos districts can reach 1.5-2.5%.
What is Mello-Roos in California?
Mello-Roos is a special tax on properties in Community Facilities Districts, common in newer developments. It funds infrastructure (schools, roads, parks) that the developer did not fully build. It can add 0.25-1.5% on top of the base property tax and runs for 20-40 years.
Does assessed value reset when I buy?
Yes. When a property is sold, the assessed value resets to the purchase price. Your 1% base tax is then calculated on this new value. Annual increases are capped at 2% from this reset point. Inherited properties may also trigger reassessment under Prop 19 (2021).
How do I pay property tax in California?
CA property tax is paid in two installments: first half due November 1 (delinquent December 10), second half due February 1 (delinquent April 10). Mortgage holders often pay through an escrow account managed by their lender.
Can I get a homeowner exemption?
Yes. The CA Homeowners Exemption reduces assessed value by $7,000 for owner-occupied primary residences. At a 1.1% effective rate, this saves approximately $77 per year. You must file with your county assessor to claim it.
