Sales tax in Fairfield County, Ohio
There is no single sales tax rate in Fairfield County. It runs from 6.75% to 7.75% depending on the exact address, because cities and special districts inside the county levy their own on top of the 5.75% state rate. The 5.75% state rate applies everywhere in the county; everything above that depends on where you are standing.
What is the sales tax rate in Fairfield County?
| Ohio state rate | 5.75% |
|---|---|
| Fairfield County rate | 1% |
| Lowest combined rate in the county | 6.75% |
| Highest combined rate in the county | 7.75% |
The two combined figures are the lowest and highest totals found anywhere inside the county. They are not a state rate plus a county rate added together, and adding the rows above will not reproduce them, because cities and special districts levy in between.
Why the rate here is not the whole story
Ohio's state sales tax rate is 5.75 percent and Fairfield County levies a permissive county sales tax of 1 percent, which puts most of the county at 6.75 percent. The Central Ohio Transit Authority (COTA) levies a further 1 percent inside the parts of the cities of Columbus and Reynoldsburg that lie in Fairfield County, so an address there pays 7.75 percent while the rest of the county pays 6.75 percent. That transit levy is neither a state tax nor a county tax, so it sits in no rate field here and adding the state and county rates together understates the rate inside the transit district. Ohio cities and villages cannot levy a general sales tax of their own. 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.

How do I find the exact rate for an address in Fairfield County?
Because the rate changes within the county, an address is the only way to get it right. Use Ohio's own lookup. A vendor's calculator is not the state speaking.
Who has to collect sales tax in Fairfield County?
A seller with a physical presence in Ohio collects at the rate for the address where the sale takes place. A remote seller collects once it passes Ohio's economic nexus threshold, which is a separate question from the rate and is covered on our sales tax nexus checker.
