Property Tax Payments
This service is for public access and is available for personal use only. To protect your privacy, we do not display an owner's name in the result of any searches you perform on this page.
Assessment vs. Fee Numbers
Your tax bill shows both an assessment (ASMT) number and a fee number. Use of the ASMT number displays that specific tax bill only. The fee number will display all tax bills associated with this property, including supplemental tax bills and defaulted tax years. We recommend using the fee number for online payments.
To access your property tax information, only enter one "Search Criteria" in the corresponding row of the chosen field; assessment number, fee parcel number or property address. For questions about your property taxes, please contact the Tax Collector's office at 707-253-4312.
If you do not receive a confirmation number at the end of your transaction, your transaction was not successful.
