The Assessor's mission is to appraise all property equally and fairly and maintain accurate assessment information for taxation purposes.

State law requires all properties to be valued at 100 percent of fair market value under RCW 84.40. Most assessment information is available online through the Lewis County Parcels website, so you can check values without calling in.

Property owners who disagree with their assessed value can appeal to the Lewis County Board of Equalization. If the Board's decision still isn't satisfactory, further appeals go to the Washington State Board of Tax Appeals at bta.wa.gov.

Lewis County PATS Parcel Search

The main online tool for Lewis County property tax records is the Parcel and Tax Information System (PATS) at parcels.lewiscountywa.gov. You can search by parcel number, owner name, or property address. Results show assessed values, property information, and tax statuses. The data comes from Lewis County's tax records and is updated annually with certified assessment rolls.

The parcel data is provided for taxation purposes, and the county notes that use of this information is at your own risk.
