Annual Secured Property Tax (real estate) bills are mailed near the beginning of October. If you do not receive your annual tax bill by November 10th, you should contact the County Tax Collector's Office. Please have your assessment number available.

What is the penalty if i don't pay my San Luis Obispo County property taxes in time?

California law requires that a ten percent (10%) delinquency penalty be added to the unpaid balance if the first installment is not paid by 5:00 p.m. on December 10th or deposited in US mail prior to midnight on the delinquency date.

If the second installment is not paid by 5:00 p.m. on April 10th or deposited in the mail prior to midnight on the delinquency date, a ten percent (10%) penalty cost plus a $20 collection cost is added to the unpaid balance.

If any installment is not paid by 5:00 p.m. on June 30th or mail deposited prior to midnight of delinquency date, then the property becomes tax-defaulted and additional penalties and fees accrue.
