When are San Joaquin County property taxes due?

The first installment is due November 1 and delinquent after 5:00 p.m. on December 10. The second is due February 1 of the following year and delinquent after 5:00 p.m. on April 10.

The county notes that you may pay the entire tax when the first installment is due, or at any time after, until the properties on the current secured roll become tax defaulted.

Because the second installment can be paid on its own only after the first is paid, an owner who skipped the first installment cannot catch up by paying only the second.

• The office is open until 5:00 p.m. on delinquent dates, later than its usual 4:30 p.m. close.
• If your lender pays through an impound account, confirm the payment posted before the delinquent date.
• Check the Tax Collector’s pay page for the payment methods currently accepted.

How do I pay my San Joaquin County property tax bill?

The Treasurer-Tax Collector’s secured taxes page links to a separate page for paying taxes or getting a copy of your bill, so start there for the current online options. You can also visit the office at 44 North San Joaquin Street, Suite 150 in Stockton, call (209) 468-2133, or email tax@sjgov.org with questions about your parcel.

What happens if I don’t pay property taxes in San Joaquin County?

Under California law a late installment takes a 10 percent penalty, and the second installment also carries a small cost. The county’s secured taxes page does not list penalty amounts, default interest or redemption fees, so confirm the exact figures for your parcel with the office at (209) 468-2133.

What the page does make clear is that once a parcel on the current roll becomes tax defaulted, you can no longer simply pay the current-year bill, and the Tax Collector’s redemption process applies. Selling before that point keeps the sale in your hands.

How to sell a house in San Joaquin County when you owe property taxes

You can sell a house in San Joaquin County with unpaid property taxes. Taxes are a lien on the home, so escrow pays what is owed from your proceeds at closing and the buyer receives the property with the taxes current.

1. Get your payoff figure. Call the Tax Collector at (209) 468-2133 or email tax@sjgov.org and ask for the amount due in the month you expect to close.
2. Expect proration. Escrow splits the current year’s tax between you and the buyer by the closing date.
3. Budget for transfer tax. The county-level rate is $0.55 per $500 of the sale price, so a $500,000 sale is $550 before any city tax. Ask escrow what applies to your address.
4. Watch the calendar. Closing before December 10 or April 10 avoids the penalty on that installment, and closing before the parcel becomes tax defaulted keeps the payoff simple.

A cash sale helps when time is the problem. There is no loan approval to wait for, so closing can be scheduled ahead of a tax deadline. See how we buy houses in San Joaquin County, our local pages for Stockton, Tracy, Manteca and Lodi, and the California real estate transfer tax report.
