How property taxes work in Washington
Washington property taxes are levied locally — typically a stack of county, municipal, school, and special-district rates applied to assessed value after any exemptions. The 0.75% figure on this page is an ACS effective rate (taxes paid ÷ owner-occupied home value), which is useful for comparing counties and modeling PITI. It is not the millage printed on a specific parcel's bill.
For millage, exemption filings, or an official estimate, use Washington Department of Revenue — Property Tax.

On a $400,000 home, the U.S. benchmark used for comparison is 0.90% ($3,600 / year).
