An Assessment Appeal Application which is postmarked by the US Postal Service on or before the filing deadline date will be considered timely filed.
|Regular Assessments||Between July 2, 2023 to November 30, 2023|
|Supplemental Assessments||No later than 60 days after postmark or the mailing date printed on the tax bill, whichever is later.|
|Escape Assessments||No later than 60 days after postmark or the mailing date printed on the tax bill, whichever is later.|
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.
