Why the rate here is not the whole story
Ohio's state sales tax rate is 5.75 percent and Adams County levies a permissive county sales tax of 1.5 percent, for a combined 7.25 percent that applies at every address in the county. Ohio cities and villages cannot levy a general sales tax of their own. No regional transit authority levies in Adams County, so the county is the only body below the state that taxes here and the county line is the tax boundary. Ohio counties and regional transit authorities may raise their levies only in multiples of 0.05 percent, the combined state, county and transit rate may not exceed 8.75 percent, and a change can only take effect at the start of a calendar quarter.
