Obtaining Your Tax Bill

Ownership Changes Backlog

Due to an extraordinary number of ownership changes, the Sonoma County Assessor’s Office is experiencing a significant backlog processing these changes. If you received a tax bill for a property you no longer own, please write “sold” on the bill and return it to our office. Should you need additional assistance please reach out to our office at (707) 565-2281 or

Secured Property Tax Bill

Annual Secured Property Tax Bills are mailed once a year in the fall to the mailing address the Assessor's office has on file. Per California State Revenue and Taxation Code (Section 2700) annual property taxes shall be payable in two installments. One bill will be mailed, on the bottom of which you will find two detachable payment stubs for each installment. If you do not receive your annual tax bill by November 10th, please contact our office to request a duplicate copy.

Please note: 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.

Sign Up for E-Billing

The Auditor-Controller Treasurer-Tax Collector Office is now offering a paperless Property Tax e-Billing System that allows you to receive your property tax bill by email. Once enrolled, you’ll receive an e-mail with a link to a copy of your property tax bill instead of a paper version in the mail. Please visit our Property Tax E-Billing section for more information about how to enroll. Please note, supplemental bills are excluded from e-billing and if applicable will be mailed to the address on file.

Supplemental Property Tax Bills

Supplemental Property Tax bills (additional taxes added after reassessment upon sale of the property) are mailed throughout the year. Copies of these bills can be retrieved in the same manner as annual Secured Tax Bills. These bills 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 the supplemental property tax on the Property Tax FAQs page for more information.

Unsecured Property Tax Bills

Unsecured Property Tax bills are generated and mailed in the first month of the fiscal year, July. If you do not receive your bill by August 10th, please contact our office using any of the methods mentioned above to request a copy. Unsecured bills have a delinquent date of August 31st at 5:00 p.m. each year. 

Impound or Escrow Accounts

If your taxes are paid through an impound account (i.e., included with your monthly mortgage payment), your lender will receive your annual tax bill, and you will receive an informational copy. Please reach out to your lender should you have any questions about who is paying your taxes.
