In San Diego County, secured property taxes are due in two installments. The first is due November 1 and becomes delinquent after December 10, and the second is due February 1, delinquent after April 10. If a due date falls on a weekend or holiday, it extends to the next business day. Payments must be received by the Treasurer-Tax Collector or USPS-postmarked on time to avoid penalties.
