  2. Appoint a Registered Agent: Designate a registered agent who will receive official legal and tax documents on behalf of your LLC. The registered agent must have a physical address in Ohio.
  3. File Articles of Organization: File the Articles of Organization with the Ohio Secretary of State, providing essential information about your LLC, such as its name, address, and registered agent details. The filing fee is $99.
  4. Create an Operating Agreement: Although not legally required in Ohio, creating an operating agreement is highly recommended. This document outlines the ownership structure, member responsibilities, and operating procedures of your LLC.
  5. Obtain an EIN (Employer Identification Number): Apply for an EIN from the IRS, especially if you plan to hire employees or operate as a multi-member LLC. This number is used for tax identification purposes.
  6. Comply with Ohio Tax Requirements: Register with the Ohio Department of Taxation and understand your obligations regarding the Commercial Activity Tax (CAT) and any applicable municipal income taxes. Even if your gross receipts are under $1M, registration may be required.
