Illinois Filing Time

If the Articles of Organization are filed online (or paper filing with the expedited fee), the processing time is about 24 hours.

If the Articles of Organization are filed in paper form, the processing time generally takes up to 15-20 business days depending on the current workload. An expedited processing fee of $100.00 for paper filing reduces the turnaround time to 24 hours from receipt of the approved Article of Organization and must be made in person at the Chicago office.

Illinois Annual Compliance Requirements

An Illinois LLC is required to file an Annual Report with the Illinois Secretary of State to maintain its existence. This report is due each year prior to the first day of the company’s anniversary month (the month in which the company is organized) and may be completed by online or paper filing. The fee to file the Annual Report by paper filing is $250.00, and online filing is $300.00 which includes a $50.00 expedited fee for 24 hr. processing time.
