How to change your registered agent in Illinois

  1. Choose your new registered agent first. Do not file the change form until you have a new agent lined up. The new agent has to consent to the appointment, and most states will not process the change without that consent in hand. If you let coverage lapse, the Illinois SOS can administratively dissolve your LLC.

    Two ways to go. Name yourself or someone you know. Nothing to pay beyond the state filing fee above, but your address goes in the public record and somebody has to be there during business hours to accept legal mail.
    Or use a service at $125/year. That keeps your address private and prepares the change form for you. If you are here because your current agent resigned, missed a delivery, or raised its price, this is usually the reason. See what Northwest charges, or compare what the major agents cost first.

  2. Get the Statement of Change of Registered Agent and/or Registered Office (Form LLC-1.36/1.37). Download the form ↗ You can file this online through the Illinois Secretary of State portal. The form requires your LLC name, the new agent name and address, and a signature. The new agent must consent to the appointment.
  3. Pay the $25 filing fee. Pay by credit card during the online filing. A small processing surcharge usually applies. Mail filings accept check or money order; confirm the exact payee on the form before you send it, because it is not the Secretary of State in every state.
  4. Notify your old agent. Once the change is processed, your old agent's responsibility ends. If you are paying them an annual fee, cancel that subscription so it does not auto-renew. Most agents do not refund the unused portion, so time the cancellation against your renewal date.
  5. Verify the change in state records. Search your LLC name on the Illinois SOS business search and confirm the new registered agent is listed. Check back after the processing window shown above.

Important to know about Illinois

  • Online filing offers both $25 routine (10-day) and $75 expedited (24-hour) tiers - it is not automatically the expedited option.
  • If your LLC is not in good standing (annual report unpaid or another lapse), you cannot file the change until the problem is fixed. The online service only accepts LLCs in good standing, and the Secretary of State cannot file any other document for you until then.
  • Mail filings require Form LLC-1.36/1.37 submitted in duplicate.

Have a service handle the change for you

Northwest will prepare and file the Statement of Change of Registered Agent and/or Registered Office (Form LLC-1.36/1.37) for you when you sign up, and it pays the state filing fee. The change is usually filed the same business day.
