Annual tax bills, which can be paid in two installments, are mailed once each year by November 1. Since the bill contains payment stubs for both installments, this is the only bill regularly mailed each year by the Tax Collector. If you do not receive your annual tax bill by November 10, you should request one by calling the Sonoma County Tax Collector's Office at (707) 565-2281 during regular business hours, Monday through Friday 8:00 a.m. to 5:00 p.m.
When you make your request, you will need to provide the Fee Parcel Number, which you can find on a previous year's tax bill, or the address of the taxed property.
You may also obtain a bill in person at the Tax Collector's Office located at the Sonoma County Administration Center, 585 Fiscal Drive, Room 100, Santa Rosa, California. This option is not recommended during tax periods due to parking problems and lengthy delays.
If your taxes are paid through an impound account (i.e., included with your mortgage payment), your lender will receive your annual tax bill, and you will receive an informational copy. Supplemental Property Tax bills (additional taxes added after reassessment upon sale of the property), however, are not sent to your lender, but are mailed directly to you. It is your responsibility to contact your lender to determine who will pay the supplemental tax bill. See our section on Supplemental Property Tax in the FAQs for more information.
It is your responsibility to obtain your annual tax bill. Failure to receive a bill does not provide a basis for excusing penalties for late payment.
