Illinois Tax Compliance
Personal Property Replacement Tax (PPRT)
LLCs taxed as partnerships must file Form IL-1065 and pay the PPRT:
- 2.5% of net income for LLCs with individual/trust partners
- 1.5% of net income for LLCs with corporate partners
- Due April 15 for calendar-year filers
- Estimated payments required if PPRT liability exceeds $500/year
Member Income Tax
LLC members pay Illinois personal income tax (4.95%) on their distributive share of LLC income on Form IL-1040 (Schedule NR for non-residents).
Registered Agent Requirements
Your Illinois LLC must always have a registered agent with a physical Illinois street address. If your registered agent changes their address or resigns, you must file an update within a reasonable time. Failure to maintain a current registered agent can result in the LLC being unable to receive service of process — and potential dissolution.
Penalties for Non-Compliance
| Violation | Penalty |
|---|---|
| Late annual report filing | $300 + $100/month |
| Administrative dissolution | Loss of good standing; cannot do business |
| Late PPRT payment | 2% per month + interest |
| No registered agent | Possible dissolution; missed legal documents |
