In our continuing effort to provide accurate and timely information to the taxpayers of King County, we are pleased to offer online data by entering the property tax account/parcel number.

The accuracy of the information you are accessing may be affected by changes. Therefore, the King County Department of Assessments can not warrant the accuracy, reliability or timeliness of the information, and shall not be held liable for losses caused by using this information. Any person or entity who relies on any information obtained from this system, does so at their own risk.

I understand that Washington State law, RCW 42.56.070.(9) prohibits the use of lists of individuals for "commercial purposes". I understand that the use for "commercial purposes" of said records may also violate the rights of the individual(s) named therein and may subject me to liability for such commercial use. I understand that "commercial purposes" means that the person requesting the record intends that the list will be used for general business purposes, including but not limited to communicating with the individual(s) named in the record for the purpose of facilitating profit expecting activity.

The advertisements on the King County Assessor’s eReal Property website are part of a pilot program to test the viability of web ads on the site. The goal of the ads is to generate revenue to support department operations and taxpayer services. Advertisements are placed in accordance with the Department of Assessments' guidelines for web advertising.

An important part of our work is to gather public feedback and to make sure the advertising does not interfere with the viewing or navigation of the Assessor's website. If you have any questions or comments, we encourage you to send them to: We want to hear from you.
