1.   I received my new assessment this past summer or fall - how do I appeal it?


Most assessment notices were mailed June 17, 2022, and the appeal deadline was August 16, 2022, at 5PM. There are very limited circumstances which may allow for late filing, such as severe illness, death in your immediate family, or absence from your place of residence for an extended time during the appeal period. If you believe you may qualify for late filing, please contact the clerk at or 425-388-3407.

2.  How do I conduct an assessment appeal with a greater chance of success?


By state law, the appellant (yourself) must overcome the Assessor's assessed value by providing clear, cogent, and convincing evidence that a different valuation is justified.

The Board of Equalization (BOE) can consider the following market-based information: comparable sales, bids or estimates for needed repairs, development restriction or easement documentation.

The BOE cannot by law consider other properties' assessments, the amount of tax paid, percentage increase of assessment, personal hardship, or other matters unrelated to the market value of your property. Please visit our FAQ for detailed information.

3.  I filed an appeal last year, but haven't received resolution. What's happening?


Your petition is in process. Most appeals are resolved within 12-18 months of filing. You may call or email to check the status at any time.

The BOE receives many appeals on properties’ assessed valuations every year. For the 2022 assessment year, we received approximately 1700 appeals. We do our best to manage these appeals in a timely manner, and we do plan to hold hearings throughout 2023 for those appeals. 

A copy of your petition has been provided to the Assessor for their review. The Assessor may contact you for more information. Then they will issue a response that supports their assessed value, or they may issue a corrected value, and it is at that point that a hearing will be scheduled before the Board of Equalization if necessary. 

We understand that it is difficult to wait, but we appreciate your patience. In the meantime, please be sure to pay your billed tax amount to avoid penalties and interest. If your appeal results in a reduction of your assessment, any overpayment will be returned to you.

About the Board

The board is an independent body organized to hear appeals of various determinations made by the assessor. It is comprised of five citizen members appointed by the Snohomish County Council, on the recommendation of the executive. The board’s goal is to provide an impartial hearing environment that protects each party’s due process rights and results in a fair decision. Board members must have knowledge of property values, and may not be an elected official or employed by an elected official. Board members are limited to three terms of three years each, and must attend training within one year of appointment or reappointment.
