How Ohio sales tax works

Ohio imposes a statewide sales tax on most retail purchases, then allows counties to levy an additional surtax. The combined rate depends on the county where the sale occurs. This calculator adds or extracts Ohio state and county sales tax using rates effective January 1, 2025.

Retailers who price from cost and margin can combine tax planning with the margin sales tax calculator. For other U.S. state tax rates, compare results with the Missouri sales tax calculator.

Ohio sales tax formulas

The Ohio Department of Taxation sets the state base rate at 5.75%. Counties add their own rate on top. To calculate tax on a pre-tax price:

Total Tax=Pre-Tax Price×rstate+rcounty100\text{Total Tax} = \text{Pre-Tax Price} \times \frac{r_{\text{state}} + r_{\text{county}}}{100}
Final Price=Pre-Tax Price×(1+rstate+rcounty100)\text{Final Price} = \text{Pre-Tax Price} \times \left(1 + \frac{r_{\text{state}} + r_{\text{county}}}{100}\right)

When you only know the tax-inclusive total, extract the embedded tax with:

Pre-Tax Price=Total Price1+rstate+rcounty100\text{Pre-Tax Price} = \frac{\text{Total Price}}{1 + \frac{r_{\text{state}} + r_{\text{county}}}{100}}

Worked example: Franklin County purchase

A $100 pre-tax purchase in Franklin County carries a combined rate of 7% (5.75% state plus 1.25% county). State tax is $5.75, county tax is $1.25, and total tax is $7.00. The customer pays $107.00 at checkout.
