California's property tax rate is 1% of assessed value, plus local voter-approved additions that vary by county and district

California's base property tax is 1% of the assessed value of your property. This rate is set by state law and applies statewide. On top of that base rate, your county and local districts (schools, fire, water, libraries) can add their own taxes, called bonds and assessments. These additions vary significantly depending on where your property sits — a home in one county might pay 1.2% total, while an identical home in another county pays 1.35% or higher.

The assessed value is not the market value of your home. Instead, it is the value assigned by your county assessor, which is usually much lower. California's Proposition 13 (passed in 1978) limits how much the assessed value can increase each year — typically 2% annually, even if your home's market value rises much faster. This means your property tax bill grows slowly unless you sell the property or make major improvements to it.

Your total property tax bill combines the 1% base rate plus all local additions. A property assessed at $500,000 with a total tax rate of 1.25% would owe $6,250 per year. The exact rate you pay depends on your specific location, so two neighbors in different school districts can have different bills even if their homes are worth the same.

Key Takeaways

  • California's base property tax rate is 1% of assessed value, set by state law and applied uniformly across the state.
  • Your assessed value is typically much lower than your home's market value and increases by no more than 2% per year under Proposition 13.
  • Local districts add taxes on top of the 1% base rate, so your total rate varies by county, school district, and special districts in your area.
  • Your property tax bill is recalculated when you buy a property, when you make major improvements, or when the county reassesses it after a disaster.
  • You can find your specific assessed value and tax rate on your county assessor's website or your property tax bill.

How assessed value differs from market value

When you buy a property in California, the county assessor sets the assessed value at the purchase price (or fair market value if you inherited it). This becomes your base. From that point forward, the assessed value can only increase by 2% per year, regardless of how much your home's actual market value rises. If you bought your home for $400,000 in 2010 and it is now worth $800,000, your assessed value might only be around $550,000.

This gap between assessed value and market value is the reason Proposition 13 is so significant. Your property tax bill stays relatively stable year to year, even as your neighborhood appreciates. However, the moment you sell the property, the new owner's assessed value resets to the new purchase price, and their tax bill jumps accordingly. The same applies if you make major renovations — the assessor may increase the assessed value to reflect the improvement.

You can look up your property's assessed value on your county assessor's website. Most counties allow free online searches by address or parcel number. Your property tax bill also lists the assessed value, so you can verify it there.

What local taxes and bonds add to your bill

On top of the 1% base rate, your county and local districts levy additional taxes. These typically include school district taxes, county taxes, city taxes (if you live in an incorporated area), and special district taxes for fire protection, water, libraries, or other services. Each of these is voted on by local voters and appears as a separate line on your property tax bill.

The total of all these additions varies widely. In some areas, the combined local rate might add only 0.15% to your bill, bringing your total to 1.15%. In others, especially areas with recent school bonds or infrastructure measures, the additions can reach 0.5% or more, bringing your total to 1.5% or higher. A county assessor's office can tell you the exact breakdown for your property, or you can review your property tax bill, which itemizes each district's portion.

These local taxes are not optional — they are levied on all property owners in the district. However, you can see which measures are coming up for a vote in your area and understand what they would add to your bill before they pass.

When your assessed value changes

Your assessed value stays at the 2% annual increase unless one of three things happens: you sell the property, you make major improvements, or the county reassesses it after a natural disaster or significant change.

If you sell, the new owner's assessed value resets to the purchase price. If you renovate — adding a room, replacing the roof, or making other substantial improvements — the assessor may increase the assessed value to reflect the added value. Minor repairs and maintenance do not trigger a reassessment. If your area experiences an earthquake, fire, or flood, the county may reassess properties in the affected zone.

You can also request a reassessment if you believe your assessed value is incorrect. The process and timeline vary by county, but most allow you to file a Proposition 8 process (for values that have declined) or a regular assessment appeal. Your county assessor's office has the forms and important date.

How to find your property tax rate and bill

Your property tax bill arrives once or twice per year, depending on your county. It shows your assessed value, the tax rate applied, and the total amount due. The bill also breaks down which districts are taxing your property and how much each contributes.

You can also find this information online. Most California county assessor offices maintain searchable databases where you can enter your address or parcel number and see the assessed value, tax rate, and sometimes a breakdown of local additions. The county tax collector's office may also have an online portal where you can view your bill and payment history.

If you cannot find your information online, contact your county assessor's office directly. They can provide your assessed value, explain the tax rate breakdown, and answer questions about how your specific property is taxed.

Differences between counties and special districts

While the 1% base rate is the same statewide, the local additions vary significantly by location. A property in one county might have a total rate of 1.10%, while the same property value in a neighboring county could be taxed at 1.40% or higher. This is because each county and district sets its own local taxes based on voter-approved measures and local needs.

Special districts add another layer. If your property is in a fire protection district, a water district, or a community services district, each of those levies its own tax. Urban areas tend to have more districts and higher combined rates. Rural areas may have fewer districts and lower rates. Your property tax bill itemizes all of these, so you can see exactly which districts are taxing you and by how much.

When comparing properties or considering a move, factor in the total property tax rate, not just the base 1%. A home in a high-tax district will cost more in annual property taxes than an identical home in a low-tax district, even if the purchase price is the same.

Frequently Asked Questions

Is property tax in California higher than other states?

California's 1% base rate is lower than many states, but the total rate (base plus local additions) varies. Some California counties end up around 1.2% to 1.3% total, which is moderate compared to states like New Jersey or Illinois. However, because California home values are often high, the dollar amount owed can be substantial even at a lower percentage rate.

Can I reduce my property tax bill?

If you believe your assessed value is too high, you can file an assessment appeal with your county assessor. If you are over 65, disabled, or a veteran, you may be may be able to access for a property tax exemption or postponement — contact your county assessor for details. Otherwise, your tax bill is set by law and cannot be reduced.

What happens to property tax if I inherit a home?

If you inherit a property, the assessed value is typically reset to the fair market value at the time of inheritance, not the original purchase price. This can result in a significant increase in your property tax bill. Some family transfers may may have access to for an exemption under Proposition 19, but the rules are specific — consult your county assessor about your situation.

Do I have to pay property tax if I own my home outright?

Yes. Property tax is owed by the property owner regardless of whether there is a mortgage. If you own your home outright, you pay the tax directly. If you have a mortgage, your lender typically collects the tax through an escrow account and pays it on your behalf.

How often does my assessed value get updated?

Your assessed value increases by up to 2% each year automatically. It is recalculated when you sell the property, when you make major improvements, or when the county reassesses after a disaster. You receive a notice of assessment change if your value increases beyond the 2% annual adjustment.
