What an LLC costs in Illinois
Illinois costs $150 to form and $75 a year after, due before your anniversary month rather than on a fixed date.
The numbers
What it owes every year
Annual report, $75, due before the first day of your formation anniversary month, starting the year after formation.
Know this before you file
A $100 late penalty applies after 60 days past the annual report deadline, and continued nonfiling risks administrative dissolution - the deadline is tied to your anniversary month, not a fixed calendar date, so it's easy to lose track of.
First-year math
$150 Articles of Organization. The $75 annual report starts the year after you form.
