San Diego property taxes are due in two installments each fiscal year, with the first half due November 1 and the second half due February 1

San Diego County Assessor's Office divides the property tax year into two payment periods. The first installment covers July through October and is due by November 1. The second installment covers November through June and is due by February 1. Both dates are firm important date — penalties and interest begin to accrue the day after each due date passes.

Your property tax bill arrives in the mail roughly 30 days before each installment is due. The bill shows the amount owed, the due date, and payment instructions. If you do not receive a bill, contact the San Diego County Tax Collector's Office directly rather than assuming you do not owe taxes. Missing a bill does not erase the debt.

Key Takeaways

  • The first property tax installment is due November 1 each year, and the second is due February 1.
  • Penalties of 10 percent are added to any amount unpaid after the due date, plus interest that compounds monthly.
  • You can pay online through the San Diego County Tax Collector website, by mail, or in person at their office.
  • If you own property jointly or have a mortgage, your lender may pay taxes from an escrow account, so check your loan documents to confirm who pays.

What happens if you miss the important date

A 10 percent penalty is added to any unpaid balance the day after the due date. Interest then accrues at 1.5 percent per month (18 percent annually) on the unpaid amount plus the penalty. These charges compound, meaning you pay interest on the interest. A $1,000 bill unpaid for six months becomes roughly $1,190 owed.

If taxes remain unpaid for five years, the county can foreclose on the property and sell it at a tax sale. The process moves slowly — you receive notices and have opportunities to pay — but the risk is real. Contact the Tax Collector's Office when ready if you cannot pay by the due date; they sometimes work out payment plans for hardship situations, though this is not may provide.

How to pay your San Diego property taxes

The San Diego County Tax Collector's Office accepts payment through three main channels. Online payment through their website (sdcounty.ca.gov/taxcollector) is the fastest method and shows confirmation when ready. You can also mail a check to the Tax Collector's Office with your bill stub, or pay in person at their office located at 1600 Pacific Highway, San Diego, CA 92101.

If you pay by mail, send your payment at least one week before the due date to account for postal delays. Postmark date does not count — the payment must arrive by the due date. Online and in-person payments processed before midnight on the due date are considered on time.

When your lender or escrow account pays taxes

If you have a mortgage, your lender may collect property taxes as part of your monthly payment and hold them in an escrow account. When this happens, your lender pays the county directly on your behalf, and you do not receive a separate bill. Check your loan documents or contact your lender to confirm whether taxes are escrowed.

Even if your lender pays taxes, you remain legally responsible if the payment is late or incorrect. Verify that your lender actually paid by checking the Tax Collector's website or calling them directly. Mistakes happen — a lender may miss a payment or explore it to the wrong property. Catching errors early prevents penalties from accumulating.

Checking your property tax status online

The San Diego County Tax Collector's Office provides an online lookup tool where you can search your property by address or assessor's parcel number (APN). This tool shows whether your taxes are current, what you owe, and when the next payment is due. You can access it at sdcounty.ca.gov/taxcollector without creating an account.

Your assessor's parcel number appears on your property tax bill and on the county assessor's website. If you cannot locate your APN, call the Tax Collector's Office at (619) 531-5700 and provide your street address. They can pull up your account in seconds and tell you the exact balance and due date.

Frequently Asked Questions

What if I pay one installment but not the other?

Each installment is treated separately. If you pay the first installment on time but miss the February 1 important date for the second, only the second installment incurs a penalty. However, both are still your legal obligation, and unpaid amounts will eventually trigger collection action.

Can I set up automatic payments for my property taxes?

The San Diego County Tax Collector's Office does not offer automatic recurring payments through their website. You can pay online each time a bill arrives, or contact your mortgage lender if they handle escrow — they typically process payments automatically. Some banks also allow you to schedule bill payments through your own account.

Do I owe property taxes if I just inherited a house?

Yes. The property owner on the assessment roll owes taxes regardless of how recently ownership changed. If you inherited the property, you are now responsible for taxes due after the transfer. Contact the assessor's office to confirm the ownership record has been updated and to receive bills in your name.

What if my property tax bill seems too high?

You can file an appeal with the San Diego County Assessment Appeals Board within 30 days of receiving your bill. The appeal process is free. You must show that the assessed value is incorrect — for example, by providing comparable sales of similar properties. The assessor's office website has appeal forms and instructions.

Is there a grace period after the due date?

No. Penalties begin the day after the due date. There is no official grace period, though the county may work with you on a payment plan if you contact them before the important date. Waiting until after the due date to ask for help makes negotiation much harder.
