Why the rate here is not the whole story
Washington charges 6.5 percent statewide and then cities, counties, transit authorities and other special purpose districts add local rates whose boundaries do not follow county lines, so a single rate for the whole county does not exist. The Department of Revenue publishes one combined local rate for each location code and does not split out the county's own share of it, so the county rate is recorded as unknown here rather than estimated. Washington counties do levy taxes of their own that apply countywide. The floor of 8.2 percent applies in the unincorporated county and in Grandview, Granger, Harrah, Mabton, and four other cities. The ceiling of 8.6 percent is in Yakima.
