Pro​​perty Assessment Appeals Process


 

To appeal an Assessor's valuation of your property from your recently mailed Valuation Notice you must file, in a timely manner, a completed appeal petition with the Island County Board of Equalization. There is no fee charged for filing an appeal. Petitions must be received by the Board on or before July 1st of the assessment year* or within thirty (30) calendar days after the date of the value change notice. If submitted by mail, petitions must be postmarked by the post office no later than the filing deadline.

The 2017 Change of Value Notice for most property owners was mailed June 1st, 2017.  If your Notice was dated June 1st, 2017 then the filing deadline for an appeal is Monday, July 3rd, 2017.

The appeal petition form must be used; a letter or phone call is not acceptable as a substitute for the petition form. You must submit separate petitions for each parcel that you want the Board to review. The appeal process is comprised of 2 steps:

  • Registering your appeal by filing the minimum information on Form A within 30 days of your assessment notice, and

  • Providing detailed evidence along with Form B (the Petitioner’s Worksheet) later in the process. Form B should be filed as early in the appeal process as possible, but at least no later than 7 business days prior to any schedule hearing for the subject property.
