About 47,000 properties in Lewis County will receive notices of updated property value assessments this week ahead of the 2026 tax season.
According to a news release from the Lewis County Assessor’s Office, the office mailed out notices of property revaluations last week.
The new values that will determine property taxes owed for 2026 are based on the “real and fair” value of properties as of Jan. 1, 2025, the office stated in a news release.
As part of its state-mandated responsibilities for assessing real and personal property, the Lewis County Assessor’s Office updates its property value assessments every year.
According to state law, the assessor’s office is responsible for valuing all properties at 100% of market value.
In addition to assessing the current value of property in the county, the assessor's office also keeps property record inventory, appraisal reports, maps of properties within the county and an assessment record of all properties in the county.
The records include basic information on each property such as ownership, a brief description, tax code area, location, sales and current value assessments.
Most of that information is available online through the Lewis County Parcels website, which allows residents to search properties by address or parcel number.
The Lewis County Assessor’s Office, like other county assessors, is responsible for allocating taxes for all governments and taxing districts from state and county taxes to those paid to fire, water and library districts.
“As for taxes, the Assessor’s Office allocates taxes for the state, the county, cities and taxing districts, such as schools and fire districts,” the news release stated. “Taxes also fund voter-approved measures for veterans, seniors, fire protection and parks. For the most part, these voter-approved measures and taxing district budget increases are responsible for changes in property taxes, not changing property values.”
The Lewis County Assessor’s Office urges any county residents who disagree with the value change of their property or who are looking for more information about the revaluation process to contact the assessor’s office at 360-740-1392 or visit the assessor’s office on the second floor of the Lewis County Courthouse in Chehalis.

Owners of property in Lewis County can also appeal the valuation of their property to the Lewis County Board of Equalization.
