How to Pay Your California Property Tax Bill
Where Your Property Tax Payment Goes and When It's Due
California property taxes are collected by your county assessor and county tax collector, not the state. You receive a bill twice a year — typically in November and February — and each bill covers a six-month period. The November bill is due by December 10, and the February bill is due by April 10. If you miss either deadline, a 10% penalty is added immediately, and additional penalties and interest accumulate monthly.
Your property tax bill funds local schools, fire departments, libraries, and county services. The amount you owe is based on the assessed value of your property, which is usually 1% of the purchase price (or the last assessed value if you bought before 1975). Even if you own your home outright, you still owe property tax every year.
If you pay through a mortgage lender, your lender may handle the payment for you using money from your escrow account — the account where you deposit extra money each month alongside your mortgage payment. If you own your home free and clear, or if your lender does not handle taxes, you pay the county directly.
Key Takeaways
- California property tax bills arrive twice yearly from your county tax collector, with payments due by December 10 and April 10.
- You can pay online, by mail, in person, or through automatic bank transfer (ACH), depending on your county's system.
- A 10% penalty is added the day after the deadline, plus additional interest that compounds monthly, so late payment costs significantly more than on-time payment.
- If your mortgage lender pays your taxes through escrow, confirm the payment went through by checking your county's online system or calling the tax collector.
- Senior homeowners, disabled homeowners, and those with very low income may reduce their tax bill through Proposition 13 protections or the Homeowners' Property Tax Exemption.
How to Pay Online, by Mail, or in Person
Each California county runs its own tax collection system, so the payment method depends on where your property is located. Most counties now offer online payment through their tax collector's website. To find your county's system, search "[Your County Name] tax collector" and look for a "Pay Your Taxes" or "Online Services" link. You will need your parcel number (found on your bill) and the bill amount.
Online payment usually costs nothing if you pay by bank transfer (ACH) directly from your checking or savings account, though some counties charge a small fee for credit or debit card payments. The payment typically posts within one to three business days, so pay at least three days before the deadline to be safe.
If you prefer to mail a check, send it to your county tax collector's office at least one week before the due date. Include your bill stub or write your parcel number on the check. Mailed payments are considered on time if they are postmarked by the deadline, not if they arrive by the deadline, so the postal service's date stamp matters.
You can also pay in person at your county tax collector's office during business hours, usually Monday through Friday. Some counties accept payment at satellite offices or authorized payment centers. Call your tax collector's office to confirm locations and hours before you go.
What Happens If You Miss the Deadline
A 10% penalty is added to your bill on the day after the deadline passes. If the December 10 deadline is missed, the penalty is added December 11. If the April 10 deadline is missed, the penalty is added April 11. This penalty is not waived even if you pay a day late.
After the first penalty is applied, additional interest accrues at a rate set by the state (currently around 0.5% per month, though this varies by year). The interest compounds, meaning you pay interest on the interest. A bill that is three months late costs significantly more than the original amount owed.
If your bill remains unpaid for several months, your county may file a tax lien against your property, which means the county has a legal claim on your home. If the bill stays unpaid for years, the county can foreclose on the property and sell it to recover the debt. This process takes time — usually at least three to five years — but it is a real consequence of sustained non-payment.
If you cannot pay by the deadline, contact your county tax collector immediately. Some counties offer payment plans or short-term deferrals, especially if you are a senior or disabled homeowner. Asking before the deadline is much more effective than waiting until after penalties have accumulated.
Paying Through Your Mortgage Lender's Escrow Account
If you have a mortgage, your lender may collect property taxes as part of your monthly payment. The lender holds this money in an escrow account and pays the county on your behalf. This arrangement protects the lender because property tax debt can be foreclosed on before mortgage debt.
Your lender should send you an escrow statement once a year showing how much they collected, how much they paid out, and what balance remains. If the statement shows a shortage (meaning they did not collect enough to cover the full tax bill), they may raise your monthly payment to make up the difference. If there is a surplus, they may lower your payment or send you a refund.
Even though your lender pays the taxes, you remain legally responsible if the payment is not made. Confirm that your lender actually paid by checking your county tax collector's website or calling them directly. Search your parcel number in the county system to see the payment history. If your lender failed to pay and a penalty has been added, contact your lender's escrow department immediately — they are responsible for the penalty, not you, and they should correct it.
Reducing Your Tax Bill Through Senior or Disability Exemptions
California offers a Homeowners' Property Tax Exemption that reduces the assessed value of your primary residence by $7,000, which lowers your annual tax bill by roughly $70 (since the tax rate is about 1%). You must own and live in the home as your principal residence. The exemption is not automatic — you must file a form with your county assessor's office, usually by the March 1 deadline for that fiscal year.
Senior homeowners (age 62 or older), disabled homeowners, and widow(er)s of deceased veterans may also reduce their tax bill through Proposition 13 protections or the Senior Citizen Property Tax Postponement Program. The postponement program allows you to delay paying property taxes until you sell the home or pass away, though you must meet strict income limits (currently around $40,000 annually for a single person, though this varies by county). Interest still accrues on the postponed amount.
To explore these programs, contact your county assessor's office or search "[Your County Name] property tax exemption." Each county has different income limits and application deadlines, so call or visit their website to confirm what you may be may be able to access for and when to file.
Understanding Your Bill and Parcel Number
Your property tax bill shows several key pieces of information: your parcel number (a unique identifier for your property), the assessed value, the tax rate, and the total amount due. The parcel number is critical — it is how the county identifies your property and how you identify yourself when paying online or calling the tax collector.
The bill also shows which fiscal year it covers. California's fiscal year runs July 1 to June 30, so a bill marked "2024-2025" covers July 1, 2024 through June 30, 2025. The November bill covers the first half of the fiscal year (July through December), and the February bill covers the second half (January through June).
If you do not receive a bill, do not assume you do not owe taxes. Contact your county tax collector to confirm your mailing address is correct. If you recently bought the property, the bill may be delayed by several months while the county processes the change of ownership. If you recently moved, update your address with the tax collector so future bills reach you.
Paying Property Taxes on a Rental Property or Commercial Building
If you own rental property or a commercial building in California, you still owe property taxes on the same schedule — bills arrive in November and February, with the same December 10 and April 10 deadlines. The tax is based on the assessed value of the building and land, not the rental income you collect.
You can deduct property taxes as a business expense on your federal income tax return (Schedule C for self-employed, or Schedule E for rental property). Keep copies of your paid bills and payment receipts for your tax records. If you use a property manager or accountant, they may handle the payment for you, but you remain legally responsible if the payment is not made on time.
Commercial properties are reassessed more frequently than residential properties, so your tax bill may change more often. If you believe your property is overassessed, you can file a Proposition 8 appeal with your county assessor within 30 days of receiving your bill, though the process and deadlines vary by county.
Frequently Asked Questions
What if I pay my property tax bill late by accident?
A 10% penalty is added the day after the deadline, and interest compounds monthly after that. Contact your county tax collector immediately to set up a payment plan if you cannot pay the full amount at once. Some counties will waive the penalty if you pay within a few days and have a good payment history, though this is not may provide.
Can I pay my property taxes with a credit card?
Most California counties accept credit card payments online, but they charge a processing fee (usually 2% to 3% of the bill amount). Paying by bank transfer (ACH) is free or nearly free and is the cheapest option. Check your county's website to see which payment methods are available and what fees apply.
What if my property tax bill is wrong?
Contact your county assessor's office to request a review of the assessed value. You can file a Proposition 8 appeal within 30 days of receiving your bill if you believe the value is incorrect. The assessor will review comparable properties in your area and may adjust your assessment. You still owe the current bill while the appeal is pending.
Do I owe property taxes if I own my home free and clear?
Yes. Property taxes are owed every year regardless of whether you have a mortgage. The tax is based on the assessed value of the property, not on whether you owe money to a lender. If you do not have a mortgage, you are responsible for paying the county directly.
Can I set up automatic payments so I never miss a deadline?
Most California counties allow you to set up automatic ACH payments through their online system. You can arrange for the payment to be deducted from your bank account on a specific date each year. This removes the risk of forgetting the deadline, though you should still check your bank statement to confirm the payment went through.
