The Iowa agent, in order

  1. Move 1

    Rule first

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

    Where this comes from: Source page legis.iowa.gov, October 2026

  2. Move 2

    Who counts as an agent

    Any individual or business with a place of business in Iowa that has agreed to serve. (Iowa Code § 489.115)

  3. Move 3

    Registered office rule

    The address has to be a place of business in Iowa. The registered office street address and the agent's business office have to match, and P.O. boxes are not accepted.

    Hire a service and your home address stays out of public view.

  4. Move 4

    Self-serve or professional

    Qualifying owners can name themselves. The recommended agents cost $99 to $149 annually.

  5. Move 5

    Get the agent on record

    A new LLC names its agent on the Certificate of Organization, filed with the Iowa Secretary of State. An LLC that changes agents files an amendment there.

    Where this comes from: Source page legis.iowa.gov, October 2026

  6. Move 6

    Recheck every year

    Anything the state sends about the biennial report goes to your registered agent. The filing costs $30 every two years, due April 1 of odd-numbered years.
