Ohio Sales Tax Calculator (2026) — Add or Reverse Tax
Ohio's combined sales tax rate is 7.29% (5.75% state + 1.54% average local). Use the calculator below to add Ohio sales tax to a price, or reverse a tax-included total to find the pre-tax price and exact tax amount.
How to use this calculator:
- Adding tax — enter a pre-tax price, pick "Add tax to price," and the calculator applies the Ohio rate to show the tax amount and final total.
- Reversing (extracting) tax — enter a total that already includes tax, pick "Extract tax from total," and the calculator divides by 1 + the rate to isolate the pre-tax price and the exact tax paid.
- Pick the rate that matches your situation: the average combined rate is a good statewide estimate, but the state-only or maximum-local rate is more precise if you know the exact city or county.
Understanding Ohio Sales Tax
Ohio's state sales tax rate is 5.75%, and local jurisdictions add an average of 1.54% on top, bringing the typical combined rate to 7.29%. Rates vary by city and county — the highest combined rate in Ohio can reach 8.00%.
Ohio also levies a state income tax, which shapes how much the state relies on sales tax revenue relative to other funding sources.

Why Reverse Sales Tax Calculation Matters
Receipts, invoices, and marketplace payouts usually show only the tax-included total — not the pre-tax price. Reversing the calculation matters for bookkeeping (separating revenue from tax collected), expense reports (reimbursing only the pre-tax cost), and price comparisons (checking what an item actually costs before Ohio's tax is applied). Because dividing by (1 + rate) is not the same as simply subtracting the rate from the total, doing this by hand is a common source of errors — the calculator above handles it exactly.

History & Rate Breakdown
Facing a severe Depression-era budget crisis, Ohio's General Assembly enacted a 3% state sales tax effective January 1, 1935, with a companion use tax following a year later. The state rate has since risen to 5.75%.
Ohio's 7.29% average combined rate layers the 5.75% state rate with county (and in some cases transit-authority) permissive taxes that average 1.54% statewide — every one of Ohio's 88 counties levies at least some additional local sales tax on top of the state rate.
Where the Money Goes
Because every Ohio county levies some local add-on, Ohio's combined rate structure functions as an effectively mandatory two-tier system — state plus county — rather than the optional local-adoption model seen in states like Nebraska or Idaho.
Business Use Case: Registering & Collecting Ohio Sales Tax
A retailer crossing Ohio's $100,000 (or 200-transaction) economic nexus threshold must register with the Ohio Department of Taxation and apply the correct county (and, where applicable, regional transit authority) rate for every delivery address, since all 88 counties charge some local rate above the 5.75% state floor.
Sales Tax Terms Glossary
Combined rate
The state sales tax rate plus any applicable local (city, county, or special district) rates — the actual rate charged at checkout in a given location.
Reverse sales tax
The process of working backward from a tax-included total to find the pre-tax price and the exact tax amount, using total ÷ (1 + rate) = pre-tax price.
Economic nexus
A sales threshold (in dollars, transaction count, or both) that obligates an out-of-state seller to collect and remit sales tax even without a physical presence in the state.
Marketplace facilitator
A platform (e.g. Amazon, Etsy, eBay) that collects and remits sales tax on behalf of third-party sellers under most states’ marketplace facilitator laws.
Real-World Example
A $500.00 purchase in Ohio at the average combined rate of 7.29%:
- Tax amount: $500.00 × 7.29% = $36.45
- Total price: $500.00 + $36.45 = $536.45
Ohio Sales Tax Compliance for Sellers
Remote and online sellers establish economic nexus in Ohio once they exceed $100,000.00 in annual sales or 200+ separate transactions. Once nexus is established, a seller must register with the state, collect Ohio sales tax at checkout, and file returns on the state's required schedule. Marketplace facilitators (Amazon, Etsy, eBay, Walmart) generally collect and remit on behalf of third-party sellers automatically.
