Ohio business law regulates the formation and maintenance of businesses registered in Ohio. Registering an LLC in Ohio requires filing a document, called an Articles of Organization, with the Ohio Secretary of State. An Ohio LLC must additionally register with the Ohio Department of Taxation to receive an Ohio tax registration number. There may be additional requirements depending on the type of LLC being formed.
File an Articles of Organization with the Ohio Secretary of State. You may use the Articles of Organization form provided by the Ohio Secretary of State (see Resources). You must provide the name of your LLC and the name and address of a registered statutory agent. The filing fee is $125 as of December 2010.
File for a Federal Employment Identification Number, or EIN, with the IRS. Either apply online or fill out IRS Form SS-4 (see Resources). Provide the name and contact information for your LLC, indicate how your LLC is classified for federal taxation purposes, the amount of employees you expect to hire and the type of business your LLC will conduct. There is no fee to obtain an EIN.
Register for an Ohio Business Gateway Account with the Ohio Department of Taxation (see Resources). Provide either your EIN, or your Social Security number if you are registering a sole proprietorship. Provide the legal name of your LLC and any corporate or trade names used by your LLC. Provide your name, address and email address. After registering with the Ohio Department of Taxation, use your Federal Identification Number to file your Ohio Commercial Activity Tax.
