California property tax: what families actually pay

Prop 13 caps annual increases at 2% — but as a new family buyer, you start at full purchase price. Here's how California property tax actually works for a primary-residence buyer.

Effective rate: 1.0%–1.5% (base 1.0% + local + Mello-Roos)National rank: Mid-pack national, but compounded by Prop 13 lock-inLast updated

California property tax is one of the most family-relevant pieces of buying-state vocabulary you'll encounter. The base rate is roughly 1% of assessed value, capped on annual growth at 2% per year (Proposition 13). That sounds simple, and the math is — but the practical effect for a new family buyer is anything but. You start at full purchase price, you pay essentially no Prop 13 advantage in your first decade of ownership, and in newer suburbs you also pay Mello-Roos on top. Long-term holders win big; first-five-year holders barely break even with cheaper-state alternatives. Here's the family-buyer breakdown.

At-a-glance

Estimated annual California property tax by home price

Estimates use a typical effective rate for California; specific bills depend on town, school district, and exemptions.

$800,000 home~$8,800/yr
$1,200,000 home~$13,200/yr
$1,800,000 home~$19,800/yr

How it works

Key mechanics

The base rate is 1% — but the real rate is higher

Proposition 13 caps the base property tax at 1% of assessed value. But local voter-approved bonds (school construction, parks, infrastructure) add 0.05–0.30%, and in newer-build communities Mello-Roos adds another 0.5–1.5%. The total effective rate ranges from about 1.05% in older established neighborhoods to 1.5%+ in newer Sun Belt-style suburbs (Folsom, Eastvale, parts of Irvine).

The 2% annual cap (the Prop 13 mechanic)

After purchase, your assessed value can grow at most 2% per year, regardless of market value. Over 10 years that's a 22% cumulative increase to assessed value; over 20 years it's 49%. Meanwhile, market values often grow 50–100% in those same windows, so long-term holders end up paying tax on a much smaller base than recent buyers next door. This is why an established neighbor with the same house pays $11,000/year while you pay $18,000/year.

Reassessment triggers (the moments you lose protection)

Three events reset the assessment: (1) sale, which is the standard case; (2) major construction — adding square footage, a new ADU, a major remodel that 'substantially equates to new construction' — which adds the construction value to the existing base; (3) certain family transfers, with much tighter rules under Proposition 19 (2020) than the previous regime. Routine maintenance, paint, kitchen refreshes, replacing windows: all fine, no reassessment.

Mello-Roos — the California-specific extra

If you're buying in a community built after about 1985, you're probably in a Community Facilities District paying Mello-Roos on top of the base 1%. Mello-Roos funds new infrastructure — most often the school district your kids will attend. Typical rates: 0.5%–1.5% additional on assessed value, often $4,000–$10,000/year on a $1M home, sunsetting after 20–40 years. The presence of Mello-Roos almost always indicates a newer-build community with newer schools.
Family takeaways

What buyers with kids should actually do

  • Run your monthly affordability math on YOUR new Prop 13 basis (your purchase price), not on the seller's existing tax bill. The seller's $11,000 number doesn't apply to you.
  • Long-term holds are heavily favored. If you plan to raise kids in one home through K-12 (15+ years), the Prop 13 cap meaningfully offsets California's high purchase prices.
  • If you're moving from Texas: California's 1.0–1.5% effective rate on a frozen base is often cheaper than Texas's 2.0–2.5% on a market-reset base over a 20+ year hold. Run the comparison both ways.
  • Major remodels are best deferred a year or two after purchase — bundling sale + construction reassessment in the same tax year exposes more value to current-market valuation.
Exemptions

California property-tax exemptions

Homeowners' Exemption

Reduces your assessed value by $7,000 if the home is your primary residence on January 1 of the tax year. Saves about $70/year. File with the county assessor in the year you buy.

Disabled Veterans' Exemption

Up to $169,769 (low-income) or $254,656 (extreme low-income) of assessed value exempt for 100%-disabled veterans on their primary residence. Substantial benefit; verify eligibility through county assessor.

Parent-to-child transfer (Prop 19)

After 2020, parent-to-child transfers preserve the parents' Prop 13 base only if the child uses the property as their primary residence within one year, and only up to a $1M+inflation cap on the value protected. Pre-2021 transfers were much more generous. Plan accordingly if a family home will eventually transfer to your kids.

FAQ

Common California property-tax questions

Does Prop 13 apply to all California property?

Yes — primary residences, second homes, rentals, commercial. The 1% base, 2% annual cap, and reassessment-on-sale rules apply universally. Prop 19 (2020) added restrictions on parent-to-child transfers but didn't change the basic mechanics for general buyers.

How is California property tax different from Texas?

Texas has no state income tax but property tax of 2.0–2.5% of full annual market value. California has state income tax but property tax of 1.0–1.5% of a frozen Prop 13 base. Over short holds (< 5 years) Texas can be cheaper. Over long holds (15+ years) California is often cheaper. The crossover depends on appreciation rates in your specific market.

Can I appeal my California property tax assessment?

Yes — within 60 days of receiving the assessment notice (deadline varies by county; typically September 15 or November 30). The strongest appeal is when comparable nearby sales come in below your assessment. For first-year buyers, appeals are rarely successful because the assessment is your purchase price; for long-term holders during market dips, appeals can be very effective.

Does property tax in California fund public schools?

Partially. Roughly 35–45% of California public school funding comes from property tax (combined with state-level funding via the Local Control Funding Formula). In Mello-Roos districts, additional school funding comes directly from the special tax. Compared to Texas (where property tax funds about 50% of schools), California schools are less property-tax-dependent — which means moving from a high-tax neighborhood doesn't automatically degrade your kids' school.
