Ohio Sales Tax and Invoicing Rules for 2026

TL;DR: Ohio charges a 5.75% state sales tax, with county additions pushing combined rates to 6.5%–8.0%. Economic nexus triggers at $100,000 in Ohio sales OR 200 transactions. Ohio uses origin-based sourcing for in-state sellers.

State sales tax rate

Ohio imposes a 5.75% state sales tax. All 88 counties levy additional county sales taxes ranging from 0.75% to 2.25%, making combined rates vary from 6.5% to 8.0%.

Cuyahoga County (Cleveland) has one of the highest combined rates at 8.0%. Franklin County (Columbus) sits at 7.5%. Hamilton County (Cincinnati) is at 8.0%.

Ohio uses origin-based sourcing for Ohio-based sellers — you charge the rate for your business location. Out-of-state remote sellers use destination-based rules, charging the rate at the buyer's address.

Nexus rules

Physical nexus applies if you have a place of business, employees, or property in Ohio.

Economic nexus triggers if you have either $100,000 in gross receipts from Ohio sales OR 200 or more transactions delivered to Ohio buyers in the current or prior calendar year. Meeting either threshold creates nexus.

Marketplace facilitators are required to collect and remit. Ohio also recognizes substantial nexus through ownership of intangible property (trademarks, patents) used in Ohio.

Invoice requirements

The Ohio Department of Taxation requires sellers to keep records supporting all sales and tax collected. Invoices should contain:

• Vendor name and address
• Vendor's license number
• Date of sale
• Buyer information
• Description of items
• Sale price
• Tax rate, tax amount, and total

Tax should be itemized separately. For exempt sales, retain a valid Ohio Sales and Use Tax Blanket Exemption Certificate (STEC-B) or unit exemption certificate. Records must be kept for the statute of limitations period — typically four years.

Exemptions and special cases

Food (off-premise consumption, not restaurant meals) is exempt. Prescription drugs are exempt. Clothing is fully taxable in Ohio.

Manufacturing machinery and equipment used directly in production is exempt. Building materials for new manufacturing facilities may qualify for exemptions.

Ohio taxes most services only when specifically enumerated — SaaS is generally not taxable as the state has not broadly classified it as taxable tangible personal property. However, electronically downloaded software (canned) is taxable. Employment services and janitorial services are among the specifically taxable services.

Filing frequency and deadlines

Ohio assigns frequency based on liability:

• Monthly — tax liability over $5,000/year
• Quarterly — between $1,200 and $5,000/year
• Semi-annual — under $1,200/year

Monthly returns are due the 23rd of the following month. Quarterly returns are due the 23rd of the month following the quarter. Semi-annual returns are due July 23 and January 23.

Ohio offers a 0.75% vendor discount on timely returns. Electronic filing through the Ohio Business Gateway is required for most filers.

Penalties for non-compliance

Late returns incur a penalty of the greater of $50 or 10% of the tax due per month (capped at 50%). Interest is assessed at the federal short-term rate plus 5%.

Failure to register and collect tax results in back-assessments to the date nexus was established. Ohio's Department of Taxation actively audits businesses and can assess penalties for negligent or fraudulent returns.

FAQ

Does Ohio's origin-based sourcing mean I always charge my local rate?

Only if you are an Ohio-based seller. In-state sellers charge based on their business origin. Out-of-state sellers shipping into Ohio must use destination-based sourcing — the rate at the buyer's delivery address. This distinction is important if you have customers across multiple Ohio counties.

Is SaaS taxable in Ohio?

Generally no. Ohio has not classified SaaS as taxable tangible personal property. Pre-written software delivered electronically (downloaded) is taxable, but cloud-based software accessed via a browser without downloading is typically not. Confirm your specific situation with a tax advisor.

What is a blanket exemption certificate?

Ohio allows buyers to provide a single blanket certificate (STEC-B) that covers all future exempt purchases from the same vendor, rather than issuing a new certificate for each transaction. Sellers should verify the certificate is properly completed and keep it on file.
