How to Pay Your San Diego Property Tax Bill
Where to send your San Diego property tax payment
San Diego County Assessor-Recorder-Clerk (ARC) collects property taxes for the county. You can pay online through their official website, by mail, in person at their office, or by phone. The mailing address and payment portal are both on the ARC website under "Pay Your Taxes." Payments made online or by phone are processed immediately; mail typically takes 7 to 10 business days to reach the office and post to your account.
If you own property in an incorporated city within San Diego County—such as San Diego, Chula Vista, or Oceanside—you still pay through the county ARC, not the city. The county collects the full bill and distributes portions to the city, schools, and other local agencies. Your bill will show the breakdown of where your money goes.

Understanding your property tax bill and payment schedule
San Diego County sends property tax bills twice per year. The first bill (for the July–December period) is mailed in November and due by December 10. The second bill (for the January–June period) is mailed in February and due by April 10. You receive one bill per parcel of land you own, and the bill shows the assessed value, the tax rate, and the total amount owed.
The bill also itemizes where your tax money goes: to the school district, county services, fire protection, water districts, and other local agencies. The total amount is not negotiable—it is set by law based on your property's assessed value and the tax rates approved by those agencies. If you believe your assessed value is wrong, you can file an appeal with the assessor's office, but that is separate from paying the current bill on time.
If you do not receive a bill by the expected month, contact the ARC office directly. A missing bill does not erase the deadline; if you do not pay by December 10 or April 10, penalties and interest begin to accrue even if you never saw the bill.
What happens if you miss a payment deadline
A 10% penalty is added to any unpaid balance on the day after the deadline passes. This penalty is automatic—you do not have to be notified. After the penalty is added, interest accrues daily at a rate set by California law (currently around 1.5% per month, but this rate changes annually). The longer you wait, the more interest you owe on top of the original tax.
If your bill remains unpaid for several months, the county may file a tax lien against your property. This lien makes it difficult or impossible to sell, refinance, or take out a loan against the property until the debt is paid. In extreme cases, the county can foreclose on the property and sell it to recover the unpaid taxes, though this process takes time and the county must follow specific legal steps first.
If you know you cannot pay by the deadline, contact the ARC office before the date passes. Some payment plans or deferrals may be available depending on your situation, though they are not may provide. Waiting until after the deadline to ask for help means you will owe the penalty regardless.
Online payment and automatic payment options
The San Diego County ARC website has a secure online payment portal where you can pay with a debit card, credit card, or bank account. You will need your parcel number (found on your bill) or your assessor's parcel number (APN). Payments made online are processed the same day and post to your account within 24 hours. There is no fee for paying by bank account transfer, but credit and debit card payments incur a processing fee (typically 2% to 3% of the amount paid).
You can also set up automatic payments through the ARC website so that your bill is paid on the same date each year without you having to remember. This is useful if you own multiple properties or want to ensure you never miss a deadline. You can change or cancel automatic payments at any time through your online account.
If you prefer not to use the website, you can pay by phone by calling the ARC office during business hours. Phone payments are also processed immediately, and the same card or bank account fees apply.
Mailing and in-person payment methods
To pay by mail, send a check or money order to the address listed on your bill. Include your bill stub or write your parcel number on the check so the payment is credited to the correct property. Mail payments take 7 to 10 business days to arrive and post, so if you are close to a deadline, mail is risky—the postmark date does not count as the payment date; the date the ARC office receives it does.
You can also pay in person at the San Diego County Assessor-Recorder-Clerk office. The main office is located in downtown San Diego, and there are satellite offices in other parts of the county. In-person payments are processed immediately and you receive a receipt on the spot. Bring your bill, your parcel number, and a check, money order, or debit card (credit cards are not accepted for in-person payments at some locations, so call ahead to confirm).
Property tax reductions and postponement programs
California law allows certain property owners to reduce or postpone their property tax bills. Senior citizens (age 65 or older), disabled persons, and disabled veterans may be may be able to access for a homeowner's property tax exemption or a reduction in assessed value. To pursue this, you must file a claim with the San Diego County Assessor's office. The exemption is not automatic; you have to request it, and the deadline to file is typically in the year you turn 65 or become disabled.
Disabled and senior homeowners may also be may be able to access for the Property Tax Postponement Program, which allows you to defer paying your property taxes until you sell the home, move, or pass away. Interest still accrues on the postponed amount, but you do not have to pay it immediately. This program has income and asset limits, and you must own and occupy the home as your primary residence.
To learn about these programs, contact the San Diego County Assessor's office directly or visit their website. Staff can explain the requirements and help you determine whether you may have access to. If you do may have access to, filing early in the year gives you the best chance of having the reduction or postponement in place before your next bill arrives.
Paying taxes on a property you just bought or sold
When you buy property in San Diego County, you become responsible for property taxes starting on the date of transfer (usually the closing date). The seller is responsible for taxes up to that date. At closing, the title company or escrow officer typically calculates a prorated amount and collects it from the buyer and seller to settle up. This prorated amount is separate from your first full bill from the county.
Your first full property tax bill from the county will arrive several months after you close. It will be based on the purchase price (which becomes the new assessed value) and will cover the July–December or January–June period, depending on when you bought. If you bought mid-year, your first bill may be prorated to cover only the months you owned it.
If you sold property, you are responsible for taxes only through the date of transfer. After that date, the new owner is on the hook. Make sure you receive a final bill or a statement from the county confirming that your account is settled, so you do not accidentally receive bills for a property you no longer own.
Frequently Asked Questions
Can I pay my property taxes with a credit card?
Yes, but only online or by phone through the county ARC website or office. Credit card payments incur a processing fee of 2% to 3%. In-person payments at the ARC office do not accept credit cards; debit cards and checks are accepted instead. Paying by bank account transfer online has no fee.
What if I own multiple properties in San Diego County?
You receive a separate bill for each parcel. You can pay each bill individually online, or you can set up automatic payments for all of them at once through your online account. Make sure you use the correct parcel number for each property so the payment is credited to the right one.
Can I get my property tax bill lowered if I think my home is overvalued?
Yes, you can file an appeal with the San Diego County Assessor's office if you believe your assessed value is incorrect. The deadline to file is usually 30 days after you receive your bill. You will need to provide evidence, such as recent sales of comparable homes or a professional appraisal. Filing an appeal does not stop you from paying your current bill on time; you still owe the full amount while the appeal is being reviewed.
What if I paid my bill but it still shows as unpaid on my account?
Check the payment date, not the date you sent it. Mail payments take 7 to 10 days to post. Online and phone payments post within 24 hours. If more than 10 days have passed since you mailed a check and it still does not show, contact the ARC office with your check number and amount. If you paid online or by phone, you should have received a confirmation number; provide that when you call.
Do I have to pay property taxes if I am behind on my mortgage?
Yes. Property taxes and mortgage payments are separate obligations. Your mortgage lender may pay your property taxes on your behalf if you fall behind (and add the cost to your loan), but you are still legally responsible for them. Failing to pay property taxes can result in foreclosure even if your mortgage is current.
