Who must register for Ohio sales tax
You must register for an Ohio vendor's license if your business has a sales tax nexus in the state. This usually applies when a business:
- Exceeds the economic nexus threshold of $100,000 in annual sales or 200 or more separate transactions into Ohio in the current or previous calendar year, or;
- Has a physical presence in Ohio, such as an office, employee, warehouse, or inventory stored in the state.
Ohio's dual threshold means you must register once you cross either the dollar amount or the transaction count, whichever comes first.
Once you exceed the threshold, you should register before making further taxable sales in Ohio. If you're unsure whether your business has nexus, see the Ohio Sales Tax Guide for a broader explanation.
How to register for Ohio sales tax
Sellers can register online through the Ohio Business Gateway, the state's centralized business services portal. This is the same portal you will use to file returns and make payments after registration.
Information you need before registering
Before applying for an Ohio vendor's license, have this information ready:
- Your Social Security number (if registering as a sole proprietor with no employees)
- Your Employer Identification Number (EIN), if your business has one (required for corporations, partnerships, and most LLCs)
- North American Industry Classification System (NAICS) code for your primary business activity
- The date of your first sale in Ohio
- Your business address and any Ohio locations, if applicable
Registration steps
Follow these steps to register for an Ohio vendor's license.
1. Create your online login
Set up your Ohio Business Gateway account credentials.
- Choose a username and password
- Set up your security information
- This login is used for all future filings, payments, and account management
If you already have an Ohio Business Gateway account, you can add a sales and use tax account to your existing login.
2. Provide your business information
Enter your business name, address, type of entity, and any Ohio locations.
- Remote sellers without an Ohio location should indicate they are selling remotely
- Ohio uses destination-based sourcing for remote sellers — you charge based on where the buyer is located (specifically, the buyer's county)
- Ohio's county rate structure means the applicable combined rate depends on which county the buyer is in
3. Application fee
Ohio charges a $25 fee for a vendor's license at the time of registration. This fee is paid online through the Ohio Business Gateway.
4. Submit your application
Review your entries and submit the application.
- You will receive an on-screen confirmation after submission
- A confirmation email is typically sent shortly after submission
5. Receive your Ohio vendor's license
Once approved, you will receive:
- Your Ohio vendor's license number (used for filing and payments)
- Your assigned filing frequency (monthly, quarterly, or annually, based on expected tax liability)
- Access to the Ohio Business Gateway for filing, payment, and account management
What happens after registration
After registering, you must begin collecting Ohio sales tax on taxable sales and file returns based on your assigned filing frequency. Note that Ohio sales tax returns are due on the 23rd of the month following the reporting period — one of the latest due dates in the US.
Ohio taxes SaaS sold to businesses (B2B) but not SaaS sold to individuals for personal use (B2C). See the Ohio Sales Tax Guide for details on taxability.
