The Iowa agent, in order

  1. Step
    1

    Understand the requirement

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

    Where this comes from: Class notes: legis.iowa.gov (October 2026)

  2. Step
    2

    Check who qualifies as an agent

    Any individual or business with a place of business in Iowa that has agreed to serve. You will find this in Iowa Code § 489.115.

  3. Step
    3

    Meet the address 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.

    Hiring a service keeps your own address off the public record.

  4. Step
    4

    Decide: serve yourself or hire someone

    Qualified owners may act as their own agent. Otherwise our graded picks charge $99 to $149 per year.

  5. Step
    5

    Get the agent on record

    New companies list the agent on the Certificate of Organization; changing agents later means filing with the Iowa Secretary of State again.

    Where this comes from: Class notes: legis.iowa.gov (October 2026)

  6. Step
    6

    Look after it year by year

    File the biennial report on time ($30, April 1 of odd-numbered years) and the agent record stays correct.
