How registration works in Iowa

  1. Section 1

    Decide if the LLC must register

    An LLC formed in another state must register with Iowa before conducting business there. The consequences of failing to register include: Iowa's courts will not hear its own claims until it registers (Iowa Code 489.902) existing contracts keep their force (Iowa Code 489.902(3))

    Reference: See sos.iowa.gov; page last consulted October 2026

  2. Section 2

    Order the certificate your home state issues

    You will need certificate of existence (good standing) from the state or country of formation, issued no earlier than 90 days.

    Ask for it close to the date of filing.

  3. Section 3

    Appoint a registered agent for Iowa

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

    Every recommended service provides the registered agent.

  4. Section 4

    Section four is the Limited Liability Company Foreign Registration Statement

    Filing is the act of registering, and the state charges $100.

    Reference: See sos.iowa.gov; page last consulted October 2026

  5. Section 5

    Keep the registration in force

    To keep the registration in force, file the biennial report for $30, January 1 to April 1 of each odd-numbered year.
