California Property Tax and Proposition 13

In California your property tax depends less on what your home is worth today than on when you bought it. Proposition 13 set that rule in 1978, and it still shapes every bill in the state.

How Much Is Property Tax in California

California property tax is capped at 1% of your home’s assessed value, plus any local bonds and special assessments that voters approved. On average, homeowners paid an effective rate of 0.70% of their home’s market value in 2024, about $700 a year per $100,000. That ranks California 32th among the 50 states (Tax Foundation).

Key facts

  • The base rate is capped at 1% of assessed value (California Constitution, Art. XIII A).
  • Assessed value rises no more than 2% a year until the home is sold or newly built on.
  • The homeowners exemption takes $7,000 off the taxable value of the home you live in (Board of Equalization).
  • Texas homeowners paid about 2 times California’s effective rate in 2024 (Tax Foundation).

How Proposition 13 Works

Proposition 13, approved by voters on June 6, 1978, taxes your home on what you paid for it, not on what it is worth now. When you buy a home or build on it, the county assessor sets its value at the purchase price or the cost of the new construction. After that the assessed value can rise with inflation, but by no more than 2% a year, however fast market prices climb (California Constitution, Art. XIII A, Sec. 2).

That is why two identical homes on the same street can have very different bills. The illustration below uses round, made-up prices and the 1% base rate only. Real bills also include local bonds and assessments.

Illustration: two identical homes, one street, the 1% base rate Owner A bought in 2006; Owner B bought in 2026. Assessed value for A grows 2% a year, the maximum.
Owner A paid in 2006 $400,000
Owner A's assessed value after 20 years at 2% $594,379
Owner A base tax $5,944
Owner B paid in 2026 $900,000
Owner B base tax $9,000
Owner B pays more each year $3,056

The longer you own, the wider the gap tends to grow. When market prices rise faster than 2% a year, a long-time owner’s assessed value falls further behind the market, and a new buyer is assessed at today’s price. When prices fall, the assessor can lower a value to reflect the decline (Art. XIII A, Sec. 2(b)).

California Homeowners Exemption

If the home is your main residence on January 1, you can take $7,000 off its taxable value, which saves about $70 a year at the 1% rate. You file once with your county assessor. File by February 15 to get the full exemption for that year (Board of Equalization).

What Proposition 19 Changed

Proposition 19, approved November 3, 2020, made it easier for some owners to keep a low tax base when they move, and harder to pass one to children. The Board of Equalization’s comparison charts lay out both halves (Board of Equalization).

California vs. Texas Property Tax

Texas homeowners paid about 2 times California’s effective rate in 2024. Texas has no state income tax, and local property taxes pay for its schools, cities and counties. Texas limits a homestead’s taxable value increase to 10% a year, against California’s 2%, and offers a $140,000 school homestead exemption against California’s $7,000.

How does Proposition 13 work?

Your home is assessed at its purchase price. After that, the assessed value can rise no more than 2% a year, however fast market prices climb, until the home is sold or newly built on. The tax is capped at 1% of that value plus voter-approved debt.

What is the California homeowners exemption?

It takes $7,000 off the taxable value of the home you live in on January 1, which saves about $70 a year at the 1% rate. You file once with your county assessor, by February 15 for the full exemption.

What did Proposition 19 change?

Homeowners 55 and older, severely disabled homeowners and wildfire or disaster victims can move their tax base to a replacement home anywhere in California, up to 3 times for those 55 and older. Parents can still pass a family home to children at the old tax base only if a child lives in it, and only up to the base value plus about $1.04 million.

What You Can Do

  1. Check that your homeowners exemption is on file with your county assessor.
  2. Read your bill’s line items. Bonds and special assessments added by local voters appear on top of the 1% base.
  3. Vote on local bond measures. They are the part of your bill that local voters control.
  4. Plan ahead for a family home. If you expect to inherit or pass on a house, read the Prop 19 rules first.
