How do I appeal my property tax assessment?

Above is a link to King County.

Factual Error Corrections – When an Appeal May Not Be Required

If you feel a mistake has been made in valuing your property, it is recommended that you contact the Department of Assessments directly before filing an appeal at (206) 296-7300 or You can review your property parcel/account information online using eReal Property at Assessor-Online Services or with the Assessor’s staff to make sure an error has not been made.

File a petition form (or file online using eAppeals) during the 60 calendar day period following the mailing date printed on their property’s value notice.

Market Timing

According to State law, the Assessor must base assessed valuations as of January 1st of each assessment year. For example, if you are appealing a 2019 assessment year valuation, for taxes payable in 2020, the valuation date at issue is January 1, 2019. From a market timing standpoint, the Board gives comparable sales occurring closest to this date most weight.  Sales that occurred before the valuation date are preferred.

Comparable Sales

The best comparables are sales located in your neighborhood, with similar land and improvement features, which sold closest to the valuation date at issue.
