All businesses operating in the State of Ohio that make taxable retail sales of tangible personal property or selected taxable services are legally required to obtain an Ohio Vendor’s License, collect state and county sales taxes, and remit these funds electronically through the Ohio Business Gateway (OBG).
Mandatory electronic filing applies to all businesses regardless of sales volume. This comprehensive guide walks you through registering an OBG account, filing monthly and semi-annual Form UST-1 returns, making electronic ACH debit/credit payments, understanding Ohio county sales tax rates, and avoiding late filing penalties.

Frequently Asked Questions (FAQ)
Do I have to file a return if I had zero sales this month?
Yes. If your business holds an active Ohio Vendor’s License, you must file a “Zero Return” on the Ohio Business Gateway for every required filing period even if zero taxable sales occurred to prevent non-filer delinquency notices and $50 late fees.
What is the difference between County Sales Tax and Transit Authority Tax?
In Ohio, individual counties can levy local sales taxes (0.75% to 1.50%), and regional transit authorities (like COTA or RTA) can levy additional transit taxes (up to 0.50%). The Ohio Business Gateway automatically aggregates these rates by county code.
