Do you have any prior or pending appeals?
  • The Assessor sends revaluation notices each year. A separate appeal must be filed each year in order to protect your appeal rights, as past or pending appeals should not be assumed to affect a subsequent year’s valuation. It is also important to keep in mind that information submitted in a previous year’s appeal remains as part of the permanent record for that petition. If you feel the information is still pertinent to the current year’s appeal, you may resubmit a copy of this data with your new appeal.


I appealed last year’s valuation but haven’t had a hearing or decision from the Board. Do I need to appeal again this year?
  • Yes! The Assessor revalues properties each year, which means you must file a new complete petition to protect your appeal rights. It is important to keep in mind that information submitted in a previous year’s appeal remains as part of the permanent record for that petition. If you feel the information is still pertinent to the current year’s appeal, you may resubmit a copy of this data with your new petition.


Why should I include comparable sales and how do I find them?
  • Sales of the subject property and/or comparable properties are the foundation of our State’s market value standard. Accordingly, comparable sales typically provide the best indicators of market value.   [RCW 84.40.030] This is particularly true for residential properties. The best comparables are sales located in your neighborhood, with similar land and improvement features, which sold closest to the valuation date at issue. Assistance in finding comparable sales is available in the Assessor’s Public Information Office, 206-296-7300, and in the Property Tax Advisor Office (for residential properties only), call: 206-477-1060. Realtors and title companies may also be resources for comparable sales.
