Appointing a Wisconsin registered agent, procedure by procedure

  1. Procedure 1: Begin with the rule

    Every LLC must name a registered agent with an in-state street address.

    Specimen: Specimen: docs.legis.wisconsin.gov, logged October 2026

  2. Procedure 2: Confirm who may act

    A Wisconsin resident, or a business entity formed in Wisconsin or authorized there, whose business office is the registered office. The agent needs an email address and has to consent. (Wis. Stat. § 183.0115)

  3. Procedure 3: Apply the address test

    The address has to be an actual physical location with a street address in Wisconsin, not solely a P.O. box, mailbox service or answering service.

    TipWith a service, the record shows its address instead of the owner's.

  4. Procedure 4: Settle who will be the agent

    The ranked agents cost $99 to $149 a year; personal service is the alternative for those who qualify.

  5. Procedure 5: Record the agent with the state

    The agent of a new LLC is named in the Articles of Organization - Limited Liability Company (Form 502), filed with the Department of Financial Institutions (DFI). An existing LLC that changes agents files an amendment at the same office.

    Specimen: Specimen: dfi.wi.gov, logged October 2026

  6. Procedure 6: Maintain accurate details

    Wisconsin learns the agent's details from the annual report ($25, every year, due end of the calendar quarter containing the LLC's anniversary date), and state notices about it reach the registered agent.
