What if I disagree with the tax bill?

If the assessee name or the property being assessed is incorrect, contact the Assessor’s Office immediately at (925) 313-7600.

If the value of the property is incorrect, contact the Assessor or if between July 2 and November 30 contact the Assessment Appeals Board. In the meantime, you must still pay the taxes by the due date in order to avoid penalties, liens and enforced collections. Should the taxes be reduced later, a refund will be issued.

Information about the appeals process can be obtained by calling (925) 335-1920 or writing to the Clerk of the Assessment Appeals Board, Suite 150, 1025 Escobar Street, 1st Floor, Martinez, CA 94553

If the tax rate is incorrect, contact the Auditor’s Office, Property Tax Division, at (925) 646-2236. 

For delinquency date or payment information, contact the Tax Collector at (925) 608-9500.
