Ohio sales tax nexus determines whether your business must collect and remit sales tax in the Buckeye State. For e-commerce sellers shipping products into Ohio, understanding nexus became critical after the 2018 Wayfair decision allowed states to require remote sellers to collect tax based solely on economic activity.
Missing Ohio’s thresholds means potential back taxes, penalties, and audit headaches. Crossing them without proper registration creates the same problem. That’s where Hands Off Sales Tax (HOST) helps! Providing nexus analysis, registration services, and ongoing compliance management so you can focus on growing your business instead of decoding Ohio tax law.
What Is Sales Tax Nexus?
Sales tax nexus is the connection between your business and a state that creates a tax collection obligation. Once you establish nexus in Ohio, you must register for a sales tax permit, collect the appropriate tax from Ohio customers, and file returns with the Ohio Department of Taxation.
Physical nexus occurs when your business maintains a tangible presence in Ohio—employees, warehouse space, inventory, offices, or temporary activity like attending trade shows. Store products in an Ohio fulfillment center or employ remote workers living in Columbus? You’ve established physical nexus.
Economic nexus triggers based solely on sales volume or transaction count, regardless of physical presence. After the Supreme Court’s 2018 South Dakota v. Wayfair ruling, states gained authority to require out-of-state sellers to collect sales tax based on economic activity alone. Ohio adopted its economic nexus standard on August 1, 2019, replacing previous affiliate and click-through nexus provisions.
For most remote sellers, economic nexus is what matters.
Ohio Economic Nexus Thresholds
Ohio requires remote sellers to collect sales tax once they exceed $100,000 in gross receipts OR 200 or more separate transactions from sales into Ohio during the current or preceding calendar year. Meeting either threshold triggers nexus.
The $100,000 calculation includes all retail sales to Ohio customers, whether taxable or exempt. Even if you sell exempt goods, those sales count toward the threshold. However, Ohio excludes wholesale transactions from the calculation. The 200-transaction threshold counts all separate retail transactions delivered into Ohio.
Ohio implemented its economic nexus law on August 1, 2019, following Wayfair. Since then, thousands of remote sellers have registered for Ohio sales tax permits.
Key point: Ohio uses a “current or preceding calendar year” measurement. Exceeded $100,000 in Ohio sales OR 200 transactions during 2024? You have nexus throughout 2025, even if 2025 volume drops below the thresholds.
How to Determine If You Have Ohio Nexus
Start by analyzing your Ohio sales data over the past two calendar years. Pull reports from your e-commerce platform, accounting software, or sales tax automation tool showing total gross receipts from Ohio customers.
Step 1: Calculate your Ohio gross receipts and transaction count for the current calendar year (year-to-date).
Step 2: Calculate your Ohio gross receipts AND transaction count for the preceding calendar year (full year).
Step 3: If either year exceeds $100,000 OR 200 transactions, you have economic nexus in Ohio.
Most e-commerce platforms can generate sales reports filtered by state. If you use sales tax software like TaxJar or Avalara, nexus monitoring features often alert you when approaching state thresholds.
Don’t forget physical nexus triggers: inventory at third-party logistics providers, employees working remotely in Ohio, or drop-shipping arrangements where suppliers ship from Ohio on your behalf.
HOST offers comprehensive nexus analysis services, examining your sales footprint across all states to identify exactly where you’ve triggered obligations, including Ohio’s specific rules.
What Happens After You Cross Ohio’s Threshold
Once you establish nexus, registration obligations begin on the first day of the month following at least 30 days after crossing either threshold. For example, if you meet the threshold on January 20, you must register by March 1.
Ohio registration occurs through the Ohio Business Gateway, the state’s online portal. You’ll need your FEIN or SSN, business legal name and structure, business address, estimated monthly sales tax liability, and banking information for electronic payments.
The state issues your Ohio Vendor’s License electronically. There’s no registration fee, though Ohio requires a $50 security deposit from some out-of-state sellers depending on projected volume.
After registration, you must collect Ohio sales tax on all taxable sales to Ohio customers. Ohio’s state rate is 5.75%, but most transactions also include county and transit authority taxes. Combined rates range from 6.5% to 8%. Cleveland charges 8%, Columbus 7.5%, and Cincinnati 7.8%.
Ohio assigns filing frequencies based on estimated tax liability: monthly (over $2,400 annual), quarterly ($600-$2,400 annual), or annual (under $600 annual). New registrants typically start with monthly filing until Ohio reviews actual collections. All returns are filed electronically through the Ohio Business Gateway, with payment due on the 23rd of the month following the reporting period.
HOST manages the entire registration process and files your Ohio returns on schedule, so you never miss a deadline.
Common Ohio Sales Tax Exemptions
Understanding what Ohio taxes helps you collect correctly.
Generally Taxable:
- Tangible personal property (physical goods)
- Digital products for business use (software, streaming, downloads)
- Software-as-a-Service (SaaS) for business use
- Clothing and apparel
Important distinction: Ohio taxes SaaS and digital products only when sold for business purposes. Sales for personal use are not taxable.
Generally Exempt:
- Groceries (unprepared food for home consumption)
- Prescription drugs and prosthetic devices
- Newspapers and magazines (by subscription)
- Manufacturing machinery and equipment
- Sales for resale (wholesale transactions)
- Custom software developed for specific clients
When selling exempt items, obtain proper exemption certificates from customers. Ohio accepts the Multistate Tax Commission’s Uniform Sales & Use Tax Certificate.
Marketplace Facilitator Laws
Ohio’s marketplace facilitator law, effective October 1, 2019, requires platforms like Amazon, eBay, Etsy, and Walmart Marketplace to collect and remit sales tax on behalf of third-party sellers.
Sell exclusively through marketplace facilitators? You likely don’t need to register. The platform handles collection and remittance. However, track your sales for nexus purposes in states where you sell through other channels.
Critical distinction: Sell both on marketplaces and through your own website? You must register and collect tax on your direct sales once you cross Ohio’s threshold. Your total Ohio sales (marketplace + direct) determine nexus, but you only collect tax on sales the marketplace doesn’t handle.
HOST helps sort through these scenarios, determining your precise obligations across all sales channels.
Penalties for Non-Compliance
Ohio enforces sales tax compliance aggressively. Failing to register, collect, or remit tax after establishing nexus exposes your business to:
- Late filing: $50 or 10% of tax due (whichever is greater)
- Late payment: 15% of unpaid tax for the first month, then 5% per month up to 50%
- Interest on unpaid tax (typically 3-7% annually)
- Lookback period: Four years from when a return was due, or indefinitely in cases of fraud
Consider a seller who crossed Ohio’s threshold in January 2023 but didn’t register until an audit notice in January 2025. They owe two years of uncollected tax (which they must pay from their own funds), plus penalties up to 50%, plus interest, which is potentially tens of thousands of dollars.
Voluntary Disclosure Agreements: Limiting Past Liability
Discovered you should have been collecting Ohio sales tax but weren’t? A Voluntary Disclosure Agreement (VDA) can limit damage.
Ohio’s VDA program allows businesses to come forward voluntarily, typically limiting the lookback period to three years and waiving many penalties. You’ll owe back taxes and interest, but avoid the worst financial consequences.
HOST facilitates VDAs with Ohio and other states, negotiating on your behalf to minimize lookback periods, secure penalty abatement, and resolve past obligations.
Multi-State Compliance: Beyond Ohio
Ohio is rarely the only state where you’ll have nexus. E-commerce businesses typically trigger thresholds in multiple states as they grow.
Each state maintains different rules: varying thresholds, lookback periods, marketplace facilitator laws, and product taxability. Managing compliance across 45+ sales tax states means tracking thresholds, registering in each state, calculating varying rates, filing on different schedules, and responding to notices from multiple tax authorities.
This complexity explains why most growing e-commerce businesses eventually seek professional help.
