Ohio charges sales tax on most internet purchases, and the Ohio internet sales tax rate runs from 6.50% to 8.00% depending on the buyer’s county. The state portion is 5.75%, and each county adds its own piece on top. Since the U.S. Supreme Court’s 2018 decision in South Dakota v. Wayfair, out-of-state online sellers with enough business in Ohio have had to collect that tax the same way a local store does.1Supreme Court of the United States. South Dakota v. Wayfair, Inc.
What Rate Applies to Your Order
The statewide rate is 5.75%.2Ohio Department of Taxation. Sales and Use Tax Every Ohio county piggybacks on that with its own local tax. The lowest combined rate anywhere in the state is 6.50%, the highest is 8.00%, and most counties land somewhere between 7.00% and 7.25%.3Ohio Department of Taxation. Sales and Use Tax Rate Map
Rate follows the delivery address. An online seller shipping orders all over the state may apply a different rate to each one, and sellers report taxable sales broken down by county on their returns. The Ohio Department of Taxation publishes an updated rate map showing each county’s current combined rate.
What’s Taxable When You Buy Online
Ohio’s sales tax reaches further than physical shipments. Three broad categories of online commerce are taxable:
- Tangible personal property. Anything physical you can touch, from electronics and clothing to furniture and auto parts. Prewritten computer software is included, whether delivered on disc or by download.4Ohio Department of Taxation. Sales and Use Taxability
- Specified digital products. Electronically transferred audiovisual works like movies and TV shows (streamed or downloaded), digital audio works like music and podcasts, and digital books.5Ohio Legislative Service Commission. Ohio Revised Code 5739.01 – Sales Tax Definitions
- Business-use technology services. Automatic data processing, computer services, and electronic information services, but only when the technology service itself is what the customer is paying for, not a professional service that happens to use a computer.5Ohio Legislative Service Commission. Ohio Revised Code 5739.01 – Sales Tax Definitions
That last category is where software-as-a-service gets complicated. Ohio generally treats SaaS as taxable when the buyer uses it for business purposes and the real value of the transaction is the data processing or information access. A cloud accounting platform is taxable. Hiring an accountant who uses cloud software to prepare your books is not.
What’s Exempt
Not every online purchase in Ohio is taxed. The exemptions that come up most often in e-commerce:
- Food for off-premises consumption. Groceries and takeout eaten off-site are exempt. Alcohol, soft drinks, tobacco, and dietary supplements don’t qualify.4Ohio Department of Taxation. Sales and Use Taxability
- Prescription medicine and medical equipment. Insulin, syringes, test strips, doctor-prescribed home medical equipment like wheelchairs and oxygen machines, and prescription eyeglasses or contacts.4Ohio Department of Taxation. Sales and Use Taxability
- Children’s and baby products. Car seats, cribs, strollers, children’s diapers, and diaper creams and wipes designed for children’s skin, provided they meet applicable safety standards.
- Feminine hygiene products. Pads, tampons, and period underwear have been exempt since April 2020.
- Items purchased for resale. A buyer who intends to resell can purchase tax-free by providing a valid exemption certificate.
- Goods shipped out of Ohio. If the buyer takes the product out of state, Ohio tax doesn’t apply.
Getting the exempt-versus-taxable call wrong cuts both ways. Collecting tax on an exempt item creates refund headaches for the buyer. Failing to collect on a taxable item leaves the seller owing the tax out of pocket.
When Out-of-State Sellers Have to Collect
An out-of-state business must register and start collecting Ohio sales tax once it crosses one of two thresholds in the current or preceding calendar year: more than $100,000 in gross receipts from sales into Ohio, or 200 or more separate transactions with Ohio buyers.6Ohio Legislative Service Commission. Ohio Revised Code 5741.01 – Definitions Crossing just one is enough.
These thresholds track the framework the Supreme Court approved in Wayfair, which held that states can require tax collection from sellers without physical presence as long as those sellers do meaningful business within the state. Once a seller crosses the line, it must register for a seller’s use tax account and begin collecting on all taxable sales delivered into Ohio. Ignoring the obligation doesn’t make it disappear. The state can assess the uncollected tax plus interest going back to the date the obligation first arose.
Selling Through Amazon, Etsy, or Walmart
If your sales go through a platform like Amazon, Etsy, or Walmart Marketplace, the platform is responsible for collecting and remitting Ohio sales tax on your behalf. Ohio law treats the marketplace facilitator as the seller on all sales it facilitates, once the facilitator meets the same $100,000 or 200-transaction thresholds that apply to individual remote sellers.6Ohio Legislative Service Commission. Ohio Revised Code 5741.01 – Definitions Major platforms cross those lines almost immediately.
If you also sell through your own website, those direct sales remain your responsibility to collect and remit separately. Keep clean records of both channels so nothing slips through the cracks at filing time.
Use Tax: What Buyers Owe Directly
Ohio’s use tax is the mirror image of its sales tax. When you buy something online and the seller doesn’t charge Ohio sales tax, you owe use tax yourself at the same combined rate. The rate and the tax base are identical. The only difference is who pays the state.2Ohio Department of Taxation. Sales and Use Tax
In practice, most consumers never pay use tax on individual purchases because major online retailers and marketplace facilitators now collect it automatically. The obligation still matters for businesses that buy supplies, equipment, or raw materials from out-of-state vendors that don’t collect Ohio tax. Those businesses need a consumer’s use tax account with the Department of Taxation and report and pay the tax directly, either monthly or quarterly depending on the amount owed.
Registering and Filing as a Seller
Before collecting any Ohio sales tax, a business must register with the Department of Taxation. You’ll need your Federal Employer Identification Number and your North American Industry Classification System code, which describes your type of business activity.7Ohio Secretary of State. Ohio Business Roadmap – Starting a Business
Most businesses register through the Ohio Business Gateway. If you already sell in multiple states, the Streamlined Sales Tax Registration System at sstregister.org lets you register in Ohio and other member states through a single application.8Streamlined Sales Tax Governing Board. Streamlined Sales Tax Governing Board The Streamlined system also offers free tax calculation and reporting tools through Certified Service Providers.
Once you’re registered, the state assigns an account number tied to all your future filings. Sellers file the Universal Sales Tax Return (Form UST-1), which requires total gross sales, total taxable sales, and the tax collected, broken down by county.9Ohio Department of Taxation. Ohio Universal Sales Tax Return UST 1 Instructions
Filing frequency depends on how much tax you collect:
- Semi-annual. Sellers with less than $1,200 in tax liability per six-month period may qualify to file twice a year.
- Quarterly. Sellers with less than $15,000 in quarterly tax liability may file every three months.
- Monthly with accelerated payments. Sellers whose annual liability exceeds $75,000 must make accelerated payments by electronic funds transfer.10Ohio Department of Taxation. How to File Sales Tax
When a buyer claims exemption, you need documentation to prove the sale was legitimately tax-free. Ohio’s standard form is the Sales and Use Tax Blanket Exemption Certificate (STEC-B). The buyer fills it out, specifies the reason for the exemption, and provides a vendor’s license number for resale purchases. You keep the certificate on file.11Ohio Department of Taxation. Sales and Use Tax Unit Exemption Certificate Without a valid certificate, you must collect the tax. If an audit turns up exempt sales with no supporting certificate, you’re on the hook for the uncollected amount.
What It Costs to Get It Wrong
Falling behind on Ohio sales tax is expensive. When the Department of Taxation issues an assessment for uncollected or unpaid tax, the unpaid amount accrues interest at 7% per year until it’s paid or turned over to the attorney general for collection.12Ohio Department of Taxation. Annual Certified Interest Rates Once the attorney general gets involved, the entire unpaid balance continues accruing interest at that same rate until paid in full.13Ohio Legislative Service Commission. Ohio Revised Code 5739.13 – Liability of Vendor and Consumer
A seller who receives an assessment has 60 days to file a written petition for reassessment. Miss that window and the assessment becomes final, with the full amount due immediately.13Ohio Legislative Service Commission. Ohio Revised Code 5739.13 – Liability of Vendor and Consumer The real danger for out-of-state sellers who never registered is that no statute of limitations protects them. If Ohio discovers years later that you should have been collecting, the state can reach back to the very first sale that triggered your obligation.
Businesses that realize they have past-due Ohio sales tax liabilities before the state finds them can contact the Department of Taxation about its voluntary disclosure program. States that offer these programs generally waive penalties and limit the look-back period to a few years in exchange for the business registering and paying what it owes. Getting ahead of the problem voluntarily is almost always cheaper than waiting to be found in an audit.
