The sales tax rate in Warren County, Ohio is 6.75%. That figure combines Ohio’s 5.75% statewide sales tax with a 1.00% county permissive tax, and because Warren County has no transit authority levy, the 6.75% rate is flat across the entire county.1Ohio Department of Taxation. State and Permissive Sales Tax Rates, by County Whether you’re shopping in Lebanon, Mason, Springboro, or a rural township along the eastern edge, the rate is the same.
Where the 6.75% Comes From
Ohio sets the statewide base at 5.75% under Ohio Revised Code 5739.02, and that portion flows to the state’s General Revenue Fund, which supports statewide operations and public school funding.2Ohio Legislative Service Commission.

The August Sales Tax Holiday
Ohio holds a back-to-school sales tax holiday each August, and during that window the 6.75% rate drops away on specific items. In 2026, the holiday runs from 12:00 a.m. on Friday, August 7 through 11:59 p.m. on Sunday, August 9.5Ohio Department of Taxation. Ohio Sales Tax Holiday 2026 Fully exempt during that weekend:
- Clothing priced at $75 or less per item
- School supplies priced at $20 or less (notebooks, pens, calculators, folders, and similar)
- School instructional materials priced at $20 or less (reference books and similar learning materials)
Ohio will not run an expanded holiday on items $500 and under in 2026, so the exemption is limited to those three categories.5Ohio Department of Taxation. Ohio Sales Tax Holiday 2026
Online and Out-of-State Purchases
Most large online retailers already collect Ohio tax at the correct Warren County rate, because remote sellers must register and collect once they hit the state’s economic nexus threshold of $100,000 in Ohio sales or 200 or more separate transactions in the current or previous calendar year.6Ohio Department of Taxation. Sales and Use Tax Marketplace facilitators like Amazon, Etsy, and eBay have also collected on behalf of their third-party sellers since September 2019, so purchases shipped from those platforms to a Warren County address include the 6.75% automatically.
If no sales tax gets collected at checkout, though, Ohio expects you to pay use tax at the same 6.75% rate.6Ohio Department of Taxation. Sales and Use Tax This typically comes up with small independent vendors, private sellers, or overseas transactions where no Ohio tax was charged. Individual consumers can report use tax on their Ohio income tax return. The Department of Taxation does enforce it, so treating it as optional carries real risk during an audit.
