How registration works in Alabama

  1. Section 1

    Decide if the LLC must register

    Alabama requires an out-of-state LLC to register first if it will do business here. The consequences of failing to register include: Alabama's courts will not hear its own claims until it registers (Ala. Code 10A-1-7.21(a)) contracts it has signed remain valid (Ala. Code 10A-1-7.21(b))

    Reference: Reference: revenue.alabama.gov, consulted October 2026

  2. Section 2

    Secure a registered agent with an address in Alabama

    Every LLC must name a registered agent with an in-state street address. The address has to be a street address in Alabama where papers can be handed to the agent. P.O. boxes are not accepted, and an agent cannot work only through a virtual office or a mail-forwarding service.

    The services listed above supply one.

  3. Section 3

    Next comes the Foreign Limited Liability Company (LLC) Application for Registration

    Complete the Foreign Limited Liability Company (LLC) Application for Registration, enclose $150, and send both to the Alabama Secretary of State, Business Entities Division.
