What Percentage Is California Property Tax?
The short answer is: California property tax is commonly described as a 1% general tax on assessed value, but the amount homeowners actually pay is often more than exactly 1% because local voter-approved debt, direct assessments, parcel taxes, Mello-Roos and special charges may be added.
1% general tax
The base California property tax system is usually explained as 1% of assessed value under Proposition 13.
Extra voter-approved debt
School bonds, city bonds and other voter-approved indebtedness can increase the effective percentage.
Direct local charges
Mello-Roos, parcel taxes, special assessments, sewer, lighting, landscape or district charges can appear as line items.
| Bill Part | What It Means | Where to Verify |
|---|---|---|
| Assessed value | The value used for tax calculation, usually maintained by the county assessor. | County Assessor website or value notice. |
| 1% general levy | The statewide base property tax concept under Proposition 13. | California BOE property tax guidance. |
| Voter-approved debt | Additional rate for approved bonds or indebtedness. | County bill line items and tax rate area. |
| Direct assessments | Parcel-specific charges that may not be based only on assessed value. | County bill and listed agency/district. |
| Penalty / prior balance | Added after late payment or unpaid prior taxes. | County tax collector or treasurer-tax collector. |
How to Calculate California Property Tax Percentage from Your Bill
A California property tax estimate should start with assessed value, not current Zillow value or purchase price alone. The actual effective percentage depends on the county tax bill and local charges.
1
Find your assessed value
Use your county assessor, not a real estate estimate.
▾
Start from your official county assessor website or use state-level guidance from the California Board of Equalization property tax page. Your assessed value may be lower than market value because of Proposition 13 rules.
2
Apply the 1% base estimate
This gives only the general tax portion.
▾
Multiply assessed value by 1%. Example: if assessed value is $700,000, the base estimate is $7,000 before voter-approved debt, direct assessments, Mello-Roos, parcel taxes or local charges.
3
Add county bill line items
This is why your total can be higher than 1%.
▾
Open your official county tax collector bill and add any voter-approved debt, fixed charges, Mello-Roos, parcel taxes, direct assessments, penalties or prior-year balances. The California Property Tax information page is useful for statewide context, but your county bill controls the amount due.
4
Calculate your effective percentage
Total bill divided by assessed value.
▾
Use this formula: total annual property tax ÷ assessed value × 100. Example: $8,400 total bill ÷ $700,000 assessed value × 100 = 1.20% effective property tax percentage.
| Example | Calculation | Result |
|---|---|---|
| Assessed value | $700,000 | County assessor value for tax purposes. |
| Base 1% | $700,000 × 1% | $7,000 |
| Local charges | Bonds + direct assessments + parcel charges | $1,400 |
| Total bill | $7,000 + $1,400 | $8,400 |
| Effective percentage | $8,400 ÷ $700,000 × 100 | 1.20% |
How to Look Up Your California Property Tax Percentage by County
California property tax lookup is county-based. The state explains the rules, but your county assessor and county tax collector show the real assessed value, tax rate area, tax bill, payment history and bill line items.
1
Identify the county where the property is located
Payment and tax bills are handled locally.
▾
Use the official county name from your deed, property address, mortgage escrow record or prior tax bill. California property taxes are not paid through one statewide payment portal; they are paid through county tax collectors.
2
Use the county assessor for assessed value
This explains the base used for the 1% calculation.
▾
Search for your county’s official assessor website from California’s official government portal or your county website. The assessor record usually helps with assessed value, ownership, parcel number, exemptions and valuation questions.
3
Use the county tax collector for bill percentage and payment
The bill shows the actual total tax and local charges.
▾
Search for the official county tax collector or treasurer-tax collector website. Use parcel number, address, AIN/APN or tax bill number to view the actual bill, installment amounts, due dates, payment status and direct assessment lines.
4
Compare total bill with assessed value
This gives the real effective property tax percentage.
▾
Divide the total annual tax bill by assessed value and multiply by 100. If the result is higher than 1%, review the local charges, bonds, Mello-Roos or assessments shown on the county bill.
Where to Pay California Property Tax Online
California property taxes are paid through the county tax collector or treasurer-tax collector where the property is located. The state does not collect every homeowner’s annual property tax bill through one universal statewide payment page.
| Task | Correct Office | What to Check |
|---|---|---|
| Pay annual secured tax | County tax collector / treasurer-tax collector | Parcel, tax year, installment, amount, fees and deadline. |
| Check assessed value | County assessor | Assessed value, exemptions, ownership and property description. |
| Ask about BOE rules | California Board of Equalization | Statewide property tax law, guidance and assessment context. |
| Tax postponement help | State Controller’s Property Tax Postponement | Eligibility for qualified seniors, blind or disabled homeowners. |
| Payment receipt | County tax collector | Confirmation number, posting date and paid status. |
1
Start from your official county website
Avoid ads and unofficial payment pages.
▾
Use your county’s official tax collector or treasurer-tax collector page. You can begin with California’s official government portal if you need to find your county, then navigate to the county’s property tax payment page.
2
Confirm parcel, installment and amount
Avoid paying the wrong property or wrong half.
▾
Before submitting payment, match parcel/APN/AIN, property address, tax year, installment, amount due, penalty status and payment fee. Many California secured tax bills have first and second installments.
3
Review online payment fees
Card and e-check rules vary by county.
▾
County payment systems may charge card processing fees or offer e-check options. Read the official payment screen carefully before final submission, especially near a delinquency deadline.
4
Save your confirmation and receipt
Keep proof until the county shows paid.
▾
Save the confirmation number, date, amount, parcel number and screenshot or receipt. If the payment does not post, these details help the county tax collector research the issue.
California Property Tax Due Dates and Penalty Timing
Most California secured property tax bills are split into two installments. Due dates and delinquency dates are not the same thing, and this is where many homeowners make expensive mistakes.
| Installment | Due Date | Delinquent After | Best Action |
|---|---|---|---|
| First installment | November 1 | December 10 | Pay before the delinquency date and save proof. |
| Second installment | February 1 | April 10 | Do not wait for another reminder if you already have the annual bill. |
| Supplemental tax bill | Bill-specific | Bill-specific | Read the separate supplemental bill carefully after a purchase or new construction. |
| Escrow payment | Mortgage servicer schedule | County deadline still matters | Confirm lender paid before the county delinquency date. |
Why California Property Tax Percentage Is Different by County, City or Parcel
Two California homes with similar market values can have different effective tax percentages. That can happen because assessed values, purchase dates, local bonds, special districts, Mello-Roos and parcel-level assessments are different.
Purchase date matters
Properties bought years apart can have very different assessed values because Proposition 13 affects how assessed value changes over time.
Location matters
School bonds, city debt, special districts and local assessments vary by city, neighborhood and tax rate area.
Parcel charges matter
Mello-Roos, parcel taxes, direct assessments and special charges can increase the effective percentage above the base 1%.
California Property Tax Relief, Postponement and Value Review Options
If the percentage or bill feels too high, the next step depends on the reason: value issue, payment issue, senior/disabled postponement, supplemental tax, or local assessment line.
| Issue | Best Official Route | What to Prepare |
|---|---|---|
| Assessed value seems wrong | County Assessor | Parcel number, value notice, comparable sales, appraisal evidence. |
| Payment or receipt issue | County Tax Collector | Confirmation number, payment date, parcel number, tax year. |
| Senior/disabled postponement | CA Property Tax Postponement | Eligibility documents, income/property information, program forms. |
| General state property tax rule | California BOE | Property type, county, assessed value issue or tax question. |

California Property Tax Percentage Tips That Prevent Wrong Estimates, Missed Bills and Payment Mistakes
These tips are useful for California homeowners, new buyers, escrow users, investors, retirees, people buying new construction, and anyone comparing county tax bills.
Use assessed value, not market value
Your tax percentage estimate should use county assessed value. Market value and assessed value can be very different in California.
Check for Mello-Roos before buying
A newer home or planned community may have Mello-Roos or community facilities district charges that raise the effective percentage.
Do not ignore supplemental bills
After purchase or new construction, a supplemental tax bill can arrive separately from the regular annual bill.
Compare effective percentage correctly
Use total tax divided by assessed value. Comparing only the county base rate hides bonds and parcel-specific charges.
Escrow users should still check
Mortgage escrow may pay the regular tax bill, but supplemental bills or corrected bills can still require homeowner attention.
Use the right office
Assessor handles value. Tax collector handles payment. BOE explains state property tax rules. Local districts may explain direct assessments.
