Licenses & Permits in Ohio
Licenses & Permits in Ohio
General Business License
Ohio requires most businesses to register for a Vendor's License with the Ohio Department of Taxation if they sell taxable goods or services. Entity registration is handled through the Ohio Secretary of State. Many Ohio municipalities levy their own income taxes (RITA — Regional Income Tax Agency, or CCA — Central Collection Agency) in addition to state taxes, and cities like Columbus, Cleveland, and Cincinnati have their own business licensing requirements. The Ohio Business Gateway portal helps streamline multi-agency registration.

Home-Based Business Rules
Ohio cities and townships regulate home-based businesses through local zoning ordinances. Columbus allows home occupations with restrictions on customer traffic, exterior commercial activity, and the proportion of home space used. Ohio's numerous suburbs have varying home occupation rules — some are very restrictive while others are permissive. Ohio's cottage food law explicitly authorizes home-based food production and direct consumer sales subject to a state-defined annual cap.
