Property Tax 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 Board.

The Assessment Appeals Board conducts 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 Board is separate and independent from the Assessor's Office.

For Fiscal Year 2023-2024, individuals and businesses seeking to appeal their property tax assessments may do so between July 2, 2024 and December 2, 2024.
