California property taxes operate under a unique system shaped by Proposition 13, the landmark 1978 ballot measure that capped base property tax rates and limited annual assessment increases. While California’s average effective property tax rate of ~0.70% is well below the national average, the state’s high home values mean homeowners often pay substantial amounts in absolute dollars.

California Property Tax Rates (2026)

MetricRate / Amount
Base rate cap (Prop 13)1.00% of assessed value
Average effective rate~0.70%
National average effective rate~0.99%
Median home value~$750,000
Median annual property tax~$5,250

Local voter-approved bonds and special assessments can push the total rate above the 1% base. In many California counties, the actual total tax rate ranges from ~1.05% to ~1.25% of assessed value when these additional levies are included.

How California Property Tax Works

Proposition 13 Framework

Prop 13 established three foundational rules that still govern California property taxes:

  1. Assessed value is set at the purchase price. When you buy a home, the county assessor records its value at the purchase price (or fair market value at the time of transfer).
  2. Annual increases are capped at 2%. Regardless of how much the market value rises, the assessed value can increase by no more than 2% per year.
  3. The base tax rate is capped at 1%. Counties cannot impose a general property tax rate exceeding 1% of assessed value.

This means a homeowner who purchased a home for $300,000 in 2005 may have an assessed value of only ~$440,000 in 2026, even if the market value has risen to $900,000. Their annual base tax would be approximately $4,400 rather than $9,000.

Proposition 19 (2021)

Prop 19 changed the rules for inherited property and portability:

  • Portability: Homeowners 55+ (or those affected by natural disaster) can transfer their Prop 13 assessed value to a replacement home anywhere in California, up to three times.
  • Inheritance: Children who inherit a parent’s home only retain the low assessed value if they use it as their primary residence. Inherited properties used as rentals or second homes are reassessed to market value.

Exemptions and Deductions

  • Homeowner’s Exemption: Reduces assessed value by $7,000, saving approximately $70/year. Available to all owner-occupied primary residences.
  • Disabled Veteran’s Exemption: Up to $161,083 reduction in assessed value (or full exemption for 100% disabled veterans).
  • Senior Citizen Property Tax Postponement: Homeowners 62+ with household income under ~$51,762 can defer property taxes until the home is sold.
  • Proposition 60/90 (now largely replaced by Prop 19): Allowed over-55 homeowners to transfer base year value to a replacement home within the same county (Prop 60) or between participating counties (Prop 90).

Comparison to National Average

MetricCaliforniaNational Average
Average effective rate~0.70%~0.99%
Median annual tax paid~$5,250~$2,700
Assessment growth cap2%/yearVaries (many states: market value)

California’s effective rate is below the national average, but the median tax paid is nearly double the national figure due to high home values. A homeowner in a median-priced California home pays ~$5,250, while a homeowner in a median-priced U.S. home pays ~$2,700.

Tips for Minimizing California Property Tax

  1. File for the homeowner’s exemption immediately after purchase. Many homeowners miss this simple $70/year savings because they never file the one-page form with their county assessor.
  2. Challenge your assessment if values decline. If market conditions cause your home’s value to drop below its assessed value, you can file a Proposition 8 reduction claim for a temporary reassessment.
  3. Use Prop 19 portability if you are 55+. Moving within California no longer triggers a full reassessment if you meet the age or disability requirements.
  4. Understand supplemental tax bills. When you purchase a home, you will receive a supplemental tax bill reflecting the difference between the prior assessed value and your purchase price, prorated for the remainder of the tax year.
  5. Plan for Mello-Roos and special assessments. Newer developments often carry Community Facilities District (Mello-Roos) charges that can add $2,000 to $10,000+ annually on top of the base property tax.

Key Takeaways

  • California’s property tax system is governed by Proposition 13, capping the base rate at 1% and annual assessment increases at 2%
  • The average effective rate of ~0.70% is below the national average, but high home values push actual tax bills well above national medians
  • Proposition 19 expanded assessment portability for seniors while limiting inherited property tax benefits
  • Supplemental tax bills and Mello-Roos assessments can significantly increase costs for new buyers
  • Filing for the homeowner’s exemption and monitoring assessments during market downturns can reduce your bill
