Sole Proprietor Instructions

Per the Ohio Secretary of State, any business entity, domestic or foreign, planning to transact business within Ohio, using a name other than his or her own personal name, must register with the Ohio Secretary of State office. Business entities must file the appropriate formation documents to register their business. Sole proprietorships and general partnerships are not required to register the business entity; however, they may need to register a trade name or report the use of a fictitious name if they are doing business in a name other than their own. For example, if you are doing business under your personal name, i.e. Bob Smith, then you do not need to register with the Ohio Secretary of State office, but if you are doing business under the name “Bob Smith Engineering,” the name must be registered with the Ohio Secretary of State office.
