Forming a Idaho LLC, section by section

  1. Section 1

    Search the register for the name

    Check the name against the Idaho register kept by the Idaho Secretary of State; this avoids a rejected filing.

    Keep a second choice on hand.

  2. Section 2

    Designate the registered agent

    Every LLC must name a registered agent with an in-state street address. An Idaho resident, or a business entity authorized to do business in Idaho. An assumed business name (DBA) cannot serve.

    The address has to be a physical street address in Idaho. P.O. boxes and commercial mailboxes are not accepted.

    The recommended services all supply the registered agent role.

  3. Section 3

    Self-filing compared with hiring help

    Both routes pay $100 to the state. The services in the ranking charge $199 more and do the forms.

  4. Section 4

    Your paperwork here is the Certificate of Organization Limited Liability Company

    This section is the legal act that creates the company: the Certificate of Organization Limited Liability Company goes to the Idaho Secretary of State, accompanied by $100 (Idaho Code § 30-25-201). The published turnaround is About 7 to 10 days.

    Reference: legislature.idaho.gov, as published October 2026

  5. Section 5

    Secure the LLC's EIN

    With the state's approval in hand, the company can ask the IRS for a federal tax number; opening a business bank account depends on it. With Mainstay Filing this section is completed for you.

  6. Section 6

    Record how the company will be run

    Ownership and management rules belong in the operating agreement, an internal record that is separate from the Idaho filing.

  7. Section 7

    Handle the recurring Idaho filing

    Idaho asks for the annual report every year, due last day of the entity's anniversary month and charges nothing for it.

    Reference: legislature.idaho.gov, as published October 2026
