Illinois annual report deadline
Illinois law says the annual report must be delivered with required fees within the 60 days immediately preceding the first day of the anniversary month.
Example: if the LLC was formed on November 14, the anniversary month is November. The report should be filed before November 1. The practical reminder window begins 60 days before November 1.
What the annual report updates
The annual report keeps the Secretary of State record current. The paper form asks for information such as:
- LLC name
- Registered agent
- Registered office
- State or country of organization
- Date organized or admitted
- Principal place of business
- Managers and any member with manager authority
- Signature from an authorized person
Changes to the registered agent or registered office are not handled casually inside the annual report. Illinois notes that changes to registered agent or office must be submitted on the proper change form.
What it does not do
The annual report does not:
- File federal taxes
- File Illinois income tax
- Register sales tax
- Register withholding
- Register unemployment insurance
- Renew local licenses
- Renew professional licenses
- Replace the operating agreement
Common mistakes
Using the anniversary day instead of anniversary month
The Illinois annual report deadline is tied to the first day of the anniversary month, not the exact formation day.
Forgetting the report because nothing changed
The report is still required even if the LLC’s information is unchanged.
Missing agent changes
If the registered agent or office changed, use the proper registered agent/office change filing.
Treating annual report as taxes
It is not a tax return. Keep tax filings separate.
