The Iowa agent, in order

  1. Task 1

    The Iowa rule in brief

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

    Source: Look it up at legis.iowa.gov; our reading dates from October 2026

  2. Task 2

    Who counts as an agent

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

  3. Task 3

    Use an office address that qualifies

    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.

    Paying a service keeps your home address out of public records.

  4. Task 4

    Decide who will hold the role

    Hiring from the recommended agents costs $99 to $149 a year; serving yourself is the option for those who qualify.

  5. Task 5

    Put the agent on the state's record

    You identify the agent in your filing with the Iowa Secretary of State, and any change is its own filing at that office.

  6. Task 6

    Watch the details

    The biennial report costs $30 every two years and is due April 1 of odd-numbered years; any notice about it comes through the registered agent.
