Illinois LLC formation
Form an LLC in Illinois.
Illinois is a large operating market with straightforward fees: $150 to file, $75 every year. The part worth planning around is the queue — routine filings run about ten business days, and the fast lane is not something you can buy online.
No charge until secure checkout. State fees shown before payment.

Why founders choose Illinois
What a Illinois LLC gives you.
1
Chicago is a genuine business base
Illinois is not a filing-address state and does not pretend to be. It is where you form when you have Illinois activity — offices, staff, customers — and forming here avoids registering an out-of-state LLC as a foreign entity on top.
2
Predictable, flat annual cost
The $75 annual report is a flat fee rather than a tax on capital or receipts. Compared with Washington's B&O gross-receipts tax or California's $800 minimum, an Illinois LLC's yearly state obligation is a knowable line item.
3
Series LLCs are available
Illinois is one of the states that recognises the Series LLC, at a $400 filing fee. For founders holding several properties or separate product lines under one umbrella, that structure exists here — though whether it suits you is a question for a lawyer, not for us.
Worth knowing before you choose
Illinois's routine queue is about ten business days, not the two to four most formation sites quote. Expedited service turns filings around in 24 hours, but requests must be made in person at the Springfield or Chicago office, so it is not a remedy available to a founder abroad. The annual report is due before the first day of your anniversary month; more than 60 days late adds a $100 penalty, and 120 days delinquent puts the entity on the path to administrative dissolution. Card payments also carry a processor fee.

FAQ
Questions about Illinois LLCs.
Specific answers for forming and running an LLC in Illinois.
View full pricing →How long does an Illinois LLC actually take?
Roughly ten business days in the routine queue. The 24-hour expedited option exists but has to be requested in person in Springfield or Chicago, which makes it impractical for founders outside the US. Plan on two weeks rather than two days.
When is the Illinois annual report due?
Before the first day of the month in which your LLC was organised, every year. Form on 14 June and it is due by 1 June each year after. More than 60 days late adds a $100 penalty, and continued delinquency leads to administrative dissolution.
Do I need to live in Illinois to form an LLC there?
No. Illinois imposes no residency or citizenship requirement on LLC members. You need a Registered Agent with a physical Illinois address, which RazorFile provides.
Is Illinois worth it if I don't operate there?
Generally no. At $150 to file with a ten-day queue and no privacy advantage, a founder with no Illinois connection is better served by Wyoming or Colorado. Illinois earns its place when the business is genuinely here.
Do I need to understand US legal paperwork?
No. RazorFile keeps the process plain-language and organised so you know what is needed, what is paid, and what happens next at every stage of your order.
What is a Registered Agent and do I need one?
A Registered Agent is required for every US LLC, regardless of where you live. They receive official government and legal correspondence on your company's behalf at a physical address in your formation state. RazorFile provides this service.
