San Diego County property taxes are due in two parts each year. The first installment is due November 1, with delinquency after December 10, and the second is due February 1, delinquent after April 10. When a due date lands on a weekend or holiday, it is moved to the next business day. Payments must reach the Treasurer-Tax Collector or be USPS-postmarked by the deadline to prevent penalties.
