Lewis County property tax rate vs the rest of Washington
Lewis County has an effective property tax rate of 0.71% — its median real-estate tax bill ($2,433) as a share of its median home value ($341,500). That is below Washington's 0.75% state average, and ranks the 11th lowest of the 39 counties in Washington.
Rates are set by local taxing bodies — the county, your city or town, and the school district — so two homes of the same value in different parts of Washington can owe very different amounts. The calculator above starts from Lewis County's 0.71% effective rate; adjust it to your exact municipality or add a homestead exemption for a closer estimate.

How Lewis County property tax is calculated
Lewis County's assessor sets your home's assessed value, and local millage rates from the county, municipality and school district are applied to it; the 0.71% effective rate rolls all of that into one share of market value. To estimate your tax, multiply your home value by 0.71% (or your exact local rate), then subtract any homestead or senior exemption you qualify for. The calculator above does this and shows both the annual bill and the monthly escrow amount.
