Important Notice
There is a $30.00 non-refundable processing fee for each Assessment Appeal Application submitted.
One Assessment Appeal Application is required for each parcel.
The property taxes you pay are primarily based on your property's assessed value as determined by the County Assessor. If you disagree with the value established by the Assessor, you can appeal that value to the Assessment Appeals Board.
Role of the Assessment Appeals Board
Please note: Prior to filing your appeal you are urged to discuss the basis of your assessment with the Assessor's staff. If you do not agree as to the taxable value, you may file an "Assessment Appeal Application." After filing within the deadline, you may still attempt to reach an agreement with the Assessor anytime up to the date set for the Assessment Appeals Board hearing.
