Illinois LLC Compliance 2026: $75 Annual Report, Taxes & Deadlines
Quick Answer
To keep your Illinois LLC in good standing, you must: (1) file the $75 annual report with the Secretary of State before the first day of your anniversary month each year, (2) maintain a registered agent with a physical Illinois address, (3) pay the 1.5% Personal Property Replacement Tax (PPRT) on net income if your LLC is taxed as a partnership or S corp, and (4) file Illinois income tax returns as required. Miss the annual report and you owe a flat $100 late penalty; prolonged non-filing leads to administrative dissolution.

Illinois Tax Compliance
Personal Property Replacement Tax (PPRT)
LLCs taxed as partnerships file Form IL-1065 and pay PPRT directly at the entity level. The Illinois Department of Revenue sets the replacement tax rate by entity type:
- 1.5% of net Illinois income for LLCs taxed as a partnership or S corporation
- 2.5% of net Illinois income for LLCs that elect C corporation status
- Due the 15th day of the 4th month after the tax year ends (April 15 for calendar-year filers)
- Estimated payments may be required if your liability is large enough — check the IL-1065 instructions
Member Income Tax
LLC members pay Illinois personal income tax (a flat 4.95%) on their distributive share of LLC income, reported on Form IL-1040 using the Schedule K-1-P your LLC issues (non-residents use Schedule NR).
Registered Agent Requirements
Your Illinois LLC must always have a registered agent with a physical Illinois street address (a P.O. box alone does not qualify). To change your agent or its office address, file Form LLC-1.36 with a $25 fee by mail. Failure to maintain a current registered agent can leave the LLC unable to receive service of process — and can lead to dissolution. For who qualifies and how to appoint one, see Illinois registered agent requirements. For a full cost breakdown including PPRT, see Illinois LLC taxes and fees.
Penalties for Non-Compliance
| Violation | Penalty |
|---|---|
| Late annual report filing | Flat $100 (on top of the $75 fee) |
| Administrative dissolution | Loss of good standing; $200 to reinstate plus back fees |
| Late PPRT / income tax payment | Late-payment penalty plus interest set by the Dept. of Revenue |
| No registered agent | Possible dissolution; missed service of process |
