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.
