How do I lookup a property tax rate / property tax bill?



You can lookup the Tax Rate Area (TRA) for a property on CCMAP, the Assessor's property mapping database.  (click here to see how to search this database). 

When you know your TRA, use the Detail of Tax Rate document for the current year, published by the County Auditor-Controller's office. This document will show the tax rate for your TRA and the tax rate breakdown.


To look up your current property tax account / bill, you can do so from the County Tax Collector's website.

To look up previous year's tax bills click here.

For more information, contact Contra Costa County Tax Collector staff at 925-957-5280.


NOTE: Property Owner's Name is not available on CCMAP.  Contact the Assessor's office for this information - (925) 313-7400.
