Illinois Annual Report: $75 to File On Time, $175 If You Don't
Illinois takes annual report compliance seriously. The filing fee is $75 per year — but miss your deadline and the state slaps on a $100 penalty, more than doubling your cost. Extended non-compliance leads to administrative dissolution. Here's everything you need to stay on the right side of this obligation.
Key Details
Filing frequency: Annual — every single year your entity exists.
Fee: $75.
Late penalty: $100 additional (total cost if late: $175).
Deadline: Before the first day of your LLC's anniversary month. If you formed on August 20, your report is due before August 1 each year.
Filing location: Illinois Secretary of State at ilsos.gov.
Consequence of extended non-filing: Administrative dissolution — your entity loses legal standing.
What the Report Covers
Your annual report confirms or updates:
- Entity name and identification number
- Principal business address
- Registered agent name and registered office address
- Names and addresses of managers/members (LLC) or officers/directors (corporation)
- Business purpose description
- Contact email
Even if nothing changed, you file. The report confirms your entity is active and your data is current.
The $100 Penalty Is Avoidable
Most businesses that pay the penalty simply forgot their deadline. The filing itself takes minutes online. The fee is $75. But once you're past your due date, $100 gets added automatically. That's $175 instead of $75 — for the exact same filing.
This is why deadline reminders matter. Knowing your date is coming gives you time to log in, confirm your information, and pay before the penalty triggers.
Additional Illinois Business Costs
Beyond the annual report, budget for:
| Obligation | Amount |
|---|---|
| LLC formation | $150 |
| Agent change (mail) | $25 |
| Agent change (online) | $75 |
| Replacement tax (LLCs taxed as partnerships) | 1.5% of partnership income |
The replacement tax is a unique Illinois obligation. If your LLC is taxed as a partnership (the default for multi-member LLCs), you owe 1.5% on the LLC's net income to Illinois.
What Dissolution Means in Practice
If you fail to file and Illinois dissolves your entity:
- Liability protection disappears — personal assets become exposed to business debts
- You lose standing to sue or enforce contracts in Illinois courts
- Bank accounts may be frozen
- Reinstatement requires paying all missed fees, penalties, and additional reinstatement charges
- Your entity name may be claimed by another business during the lapse
