Don't miss your filing deadline! Taxpayers must file a complete appeal petition form (both pages) for each parcel being appealed. Petitions must be received by the Board of Equalization on OR before July 1st of the assessment year* OR within thirty (30) calendar days after the date of the value change notice (or other notice of determination). Petitions submitted by mail must be postmarked by the post office no later than the filing deadline (WAC 458-14-056(4)).

Please be advised that "Emailed or Faxed" Petitions are acceptable only for the purpose of protecting a deadline to file. You must still submit the original Petition with signature to our office. Assessment year is the year before the tax is due. Under very limited conditions, late petitions or appeals for previous assessment years may be accepted. (WAC 458-14-056; 458-14-127).
