If you think that an error has been made in the valuation of your property, call the Assessor's Office at 360.337.5777, and discuss your concern with a county appraiser. The appraiser will examine the valuation of your property and may initiate further review. If you are still not satisfied, you may appeal the valuation to the Kitsap County Board of Equalization. You may appeal your valuation within 60 days of the mailing date of your Change of Value Notice or by July 1 each year, whichever is later.
**3,073 change-of-value notices were mailed on October 9, 2026. The notices are dated October 12, 2026, marking the start of the 60-day appeal period. These notices are a result of new construction or miscellaneous actions the office has processed that have impacted your property value. State law requires the Assessor to add all new construction to the tax roll based upon its percentage of completion as of July 31st each year. Even though you may have received a change of value notice from the office earlier in the year, this revised value will be used to calculate your 2027 property tax obligation. Notices are only sent when the value of a property changes. If you do not receive a notice, you may still have the right to appeal, please contact the Board of Equalization for more information on the appeal process.**
For more information or an appeal packet, please contact the Clerk of the Board of Equalization at 360.337.4424 or visit their webpage at: Board of Equalization.

The appeal process is informal and does not require an attorney. However, you are required to submit clear and convincing evidence that the Assessor's valuation of your property is not correct. If you are not satisfied with the decision of the Board of Equalization, you may then appeal to the Washington State Board of Tax Appeals, which is also an informal process.
