Forming the LLC, in order

  1. Step 1: Choose a name and check it is free

    Before you file, look the name up in the business records at the Iowa Secretary of State; a name already in use can send the filing back.

    TipCheck the matching web domain at the same time.

  2. Step 2: Pick your registered agent

    Every LLC must name a registered agent with an in-state street address. Any individual or business with a place of business in Iowa that has agreed to serve.

    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.

    TipEach pick above can serve as the registered agent.

    Doing it yourself costs $50. Using one of our picks adds $199, and the agent comes with it.

    File the Certificate of Organization with the Iowa Secretary of State; the fee is $50 (Iowa Code § 489.201).

  5. Step 5: Request an EIN

    Wait for the state's approval, then get the EIN from the IRS. You need it to open accounts in the LLC's name. This step is included with Mainstay Filing.

  6. Step 6: Put an operating agreement in writing

    Even with one owner, a written operating agreement for the Iowa LLC is worth having in your records.

  7. Step 7: Stay in good standing with Iowa

    Mark the biennial report in your calendar: every two years, due April 1 of odd-numbered years, fee $30.
