How Much an LLC Costs in Illinois
Forming an LLC in Illinois requires paying a one-time filing fee to the Illinois Secretary of State. As of Q2 2026, that fee is $150. This amount is due at the time the Articles of Organization are submitted and covers the state's cost of processing and registering the new entity.
Illinois LLCs are subject to an annual report requirement, which carries a filing fee of $75 each year. This fee is due on a recurring annual basis for the life of the LLC. There are no additional special cost callouts provided in the available facts beyond this standard annual obligation.
Online submissions to the Illinois Secretary of State have taken approximately 5 to 10 business days to process, while mail submissions have taken approximately 7 to 14 business days, not counting transit time in either direction. These figures come from a single source and are indicative only, not guaranteed. Illinois state fees are subject to change at fiscal-year boundaries, so the Illinois Secretary of State's official fee schedule remains the authoritative source for current and future filing costs before submitting any documents.
