Frequently Asked Questions
How much does it cost to form an LLC in Illinois?
Forming an LLC in Illinois requires a $150 state filing fee (Articles of Organization). Add $125/year for a registered agent service and $$75/year for the annual report — total first-year cost is approximately $350.
Should I form my LLC in Illinois or another state?
If you conduct business primarily in Illinois, form your LLC here. Forming in another state (Wyoming, Delaware, New Mexico) and then operating in Illinois requires paying foreign registration fees in Illinois anyway — you end up paying both states' fees. Wyoming or New Mexico make sense only if you genuinely have no state-specific business presence and want lower costs or more privacy.
Do I need a registered agent in Illinois?
Yes — Illinois law requires every LLC to maintain a registered agent with a physical street address in Illinois during normal business hours. You can serve as your own registered agent if you have a Illinois address, but most business owners use a professional service ($50–$300/year) for privacy (your name and address are kept off public records) and reliability (someone is always available during business hours).
What are the annual costs to maintain an LLC in Illinois?
Annual Illinois LLC costs: Annual report fee: $75. Registered agent: $50–$300/year. Add bookkeeping/accounting ($100–$500/month) and business insurance ($500–$2,000/year) for a realistic total operating cost.
