How to File Illinois LLC Articles of Organization

A lot goes into the conception and planning of a new business. It is the Articles of Organization that make the LLC official. Being prepared before sitting down to complete the application will help you finish it efficiently.

First, have all of the required information handy. You will be asked for the following information:

  • The name and address of the Illinois LLC
  • The purpose for which it is being organized
  • The name and address of the registered agent (P.O. Box not acceptable)
  • The effective date of the articles (up to 60 days of filing date)
  • The dissolution date (if one applies)
  • Optional provisions for the regulation of LLC internal affairs
  • The name and address of the manager(s)
  • The name(s), address(es), and signature(s) of the organizer(s)

Second, the cost of filing the Articles of Organization is $150 ($250 for expedited processing), so have a credit card or check ready to go.

Finally, processing time varies depending on which option you choose. If you’re in a hurry, consider the online option which will process within 24 hours. Standard processing will take 10 to 15 business days. Expedited processing (24 hours) is available when filing in person.


Filing Options

When filing the Articles of Organization, use one of the three methods below.


Filing online includes automatic expediting. Therefore, an additional $100 fee will be automatically added to the $150 regular filing fee. Processing will take 24 hours, excluding holidays and weekends.

Online processing does have several restrictions:

  • It cannot have a post-effective date.
  • The general purpose section must be completed.
  • It cannot include optional provisions.
  • It must include a “perpetual duration.”
  • It cannot have more than eight initial managers.
  • It can only have one organizer.


The original completed application plus one copy need to be included with a certified check, cashier’s check, money order, or check from an Illinois attorney or accountant. The check is payable to the Secretary of State. Expedited processing is not available when filing through the mail.

Application materials can be sent to the following address:

Secretary of State

Department of Business Services Limited Liability Division

501 S. Second St., Rm. 351

Springfield, IL 62756

In Person

See the application and payment requirements for the mailing option. The application can be delivered in person to either the Springfield address listed above or to the Chicago address below:

Illinois Secretary of State

Division of Business Services

69 W. Washington St., Suite 1240

Chicago, IL 60602

Expedited processing is available  in either the Springfield or Chicago office.


Want Help Filing Your Articles of Organization?

If you decide to use your time building your business rather than completing paperwork, but don’t want to spend the money on an attorney, an LLC formation service is a great compromise.

Lots of online incorporation services are out there but do vary in perks offered, processing times (theirs, not the state’s), and price.

In general, a service will collect and review your information, prepare the documents, and send them to the Illinois Office of the Secretary of State / Department of Business Services. They will contact you when the Articles of Organization have been filed.

One additional benefit offered by some services is a free year of registered agent service. Others offer order tracking or notifications of future legal requirements needed with the state.

After reviewing all the top LLC services available, we found IncFile and Northwest Registered Agent the best overall options. While neither of them have as high brand power as the industry giant, LegalZoom, both services have great customer support, prices and offer a free registered agent.
