The map of Ohio sales tax rates, along with the same information in table form, is available at Tax.Ohio.gov, the official website of the Ohio Department of Taxation. The rate varies by county and falls between 8 percent and 6.5 percent, as of 2015.
Ohio has 88 counties, and more than half of them have a sales tax rate of 7.25 percent. The highest sales tax rate in Ohio is in Cuyahoga County, where the rate is 8 percent. The rate is only 6.5 percent in Lorain, Wayne, Stark and Butler Counties, reports the Ohio Department of Taxation.
Retailers in Ohio, as well as certain service providers, must collect a tax after making retail sales to consumers. This "trust" tax entrusts the tax to the retailer, and the retailer then bears the responsibility of reporting and paying the tax to the state, according to the Ohio Department of Taxation. The state tax rate in Ohio in 2015 is 5.75 percent, but each county's tax is higher because the county, as well as any regional transit authority, has the discretion to levy its own sales tax on top of the state tax, provided the total sales tax remains less than 8.75 percent.
