What Happens If You Miss the Deadline

Stage 1

First day of the second month after the anniversary month

Under 805 ILCS 180/50-15(b)(1) a $100 penalty is triggered, plus another $100 for each year or fraction of a year the report stays unfiled.

✓ Fix:Yes. File the annual report and pay the $75 fee plus the $100 penalty.
Stage 2

Continued delinquency

An Illinois LLC that remains delinquent can be administratively dissolved. The statutory number of months before dissolution is not published.

✓ Fix:Yes. Reinstatement costs $200 under 805 ILCS 180/50-10.

How to Fix It: Step-by-Step

1

File the Overdue Annual Report

Complete the annual report online through the Illinois Secretary of State website at https://www.ilsos.gov or mail the paper form with $75 fee.

2

Pay All Required Fees

Submit the $75 annual report fee. If administratively dissolved, reinstatement costs a flat $200 under 805 ILCS 180/50-10; it does not scale with how long the LLC has been dissolved.

3

Request Reinstatement if Dissolved

If your LLC was administratively dissolved, file Articles of Reinstatement with the Secretary of State, which cost $200 under 805 ILCS 180/50-10, along with all overdue annual reports and fees.

4

Verify Good Standing Status

Request a Certificate of Good Standing from the Illinois Secretary of State to confirm your LLC is properly reinstated and compliant.

🚨 Reinstatement After Dissolution

Reinstatement Possible?
Yes
How Long Allowed
The filing office has not published a reinstatement deadline that we have been able to verify; confirm your entity's status with it before applying. The fee is $200.
Reinstatement Fee
$200 under 805 ILCS 180/50-10, plus all overdue annual report fees
What You Lose During Dissolution
Good standing, and with it the certificate of good standing that banks, lenders and licensing bodies ask for. The LLC continues to exist for winding up, so this does not by itself void the liability shield, but the company cannot carry on ordinary business and its name protection is at risk until it is reinstated.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state publishes about filing deadlines, fees, and the consequences of missing them, with the sources this page cites. It cannot tell you what your own company owes: the date turns on when and where you formed, states change these rules between our reviews, and in several states an entity-level tax falls due in a year when no report does. Confirm your own dates with the filing office named on this page before you rely on one here, because the penalty for missing a deadline can be administrative dissolution of the company.
