San Joaquin County Treasurer-Tax Collector Phonxay Keokham, CPA, announced that property tax bills for the 2025–2026 fiscal year have been mailed to all county property owners.
If you own property in San Joaquin County and haven’t received your bill by November 10, 2025, you can easily access it online at sjcttc.org or contact the Treasurer-Tax Collector’s Office at 44 N. San Joaquin Street, Suite 150, Stockton, or by calling (209) 468-2133.
