Step by step

How to form an LLC in Illinois

Every cost below matches the breakdown above, including the card processing the state adds at checkout. See the full done-for-you Illinois formation flow →

  1. 1

    Pick and check your Illinois LLC name

    Free

    Search the Illinois business registry for your exact name, make sure it ends with "LLC" or "L.L.C.", and avoid restricted words like bank or insurance. Name reservation is optional in most states.

  2. 2

    Appoint a registered agent

    $0 yourself · ~$129/yr commercial

    Every Illinois LLC needs a registered agent with a physical in-state street address available during business hours. You can act as your own agent if you live in the state; otherwise use a commercial agent.

  3. 3

    File the Articles of Organization (Form LLC-5.5)

    Illinois state fee — $156

    File the Articles of Organization (Form LLC-5.5) online with the Illinois Secretary of State at https://www.ilsos.gov/departments/business_services/home.html. Standard approval takes 10 days. The state fee is charged as $156 at checkout.

  4. 4

    Optional: pay for expedited processing

    $100

    Illinois will move your filing to the front of the queue and approve it in 1 day instead of 10 days.

  5. 5

    Get your EIN from the IRS

    Free direct · $80 with our EIN service

    Apply online at IRS.gov once your LLC is approved. It is free and issued immediately for US residents; non-residents file Form SS-4 by fax or mail, or use our EIN service.

  6. 6

    Write an operating agreement

    Free template · ~$50 drafted

    Not filed with the state, but banks ask for it and it settles ownership, profit splits and what happens if a member leaves.

  7. 7

    File your BOI report with FinCEN

    Free direct · $50 with our BOI service

    Report your beneficial owners to FinCEN within the deadline that applies to your formation date. Filing directly is free.

  8. 8

    Open a US business bank account

    Varies by provider

    Use your approved Articles, EIN letter and operating agreement. Non-residents typically use Wise, Payoneer, Airwallex or Mercury-style accounts.

  9. 9

    Calendar your Annual Report (Form LLC-50.1)

    $75

    Illinois requires the annual report every year (Annual report due before the first day of the anniversary month), starting the year after formation. Missing it risks penalties and administrative dissolution.
