Assessment Appeals
The property taxes you pay are primarily based on your property's assessed value as determined by the County Assessor. If you disagree with value established by the Assessor, you can appeal that value to the Assessment Appeals Boards.

The Assessment Appeals Boards conduct hearings on property assessment disputes. Acting on the basis of relevant evidence submitted at the hearing, it is their role to make a fair, impartial decision on all property assessment disputes appealed, between taxpayers and the Assessor. The Assessment Appeals Boards are separate and independent from the Assessor's Office.

The Assessment Appeals Boards are quasi-judicial bodies composed of three members appointed by the Board of Supervisors. These Boards are administered by the Clerk of the Board of Supervisors. The Board members have professional experience in the fields of real estate, property appraisal, accounting, law, or similar areas. Property owners in the County of Solano may file an Application for Changed Assessment with the Clerk of the Board of Supervisors. The filing period begins on July 2, 2023 and ends on November 30, 2023. There is a $35 fee per application for this service.  The application, instructions and helpful guides can be found below.
