Deadline for Filing Appeals

Petitions must be received by the Board on or before July 1 of the assessment year*  OR  within 30 calendar days after the date of the value change notice, from the Assessor. If submitted by mail, petitions must be postmarked by the post office no later than the filing deadline.

Remember when calculating your deadline some months have more than 30 days. For example, October has 31 days, so for an Assessor's determination that is dated October 21 the appeal must be filed by November 20.

* Please note: 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} Please contact our office regarding these conditions.

Weekend or Holiday

If the last day to file falls on a weekend or holiday, the deadline for filing is the next business day. A petition filed by mail shall be postmarked no later than the filing deadline. If you are appealing other assessor determinations, for example, denial of a senior exemption, or destroyed property, you also have 30 days from the date of the mailing notification.
