The $150 state fee, the paperwork, the registered agent requirement — here's exactly what it costs, how long it takes, and the fastest legitimate path to an approved LLC.
Illinois keeps this straightforward — get the order right and you're filed within a week or two, without the guesswork.
Must include "LLC" or "L.L.C." — run it through the Illinois Secretary of State's business search first, since a taken name is the #1 reason filings bounce.
Non-negotiable under Illinois law. Needs a real street address, staffed during business hours — no P.O. boxes.
Your Articles of Organization, filed online or by mail with the Illinois Secretary of State for a $150 fee. This is the step that makes it official.
Free straight from the IRS — you'll need it before a bank will let you open a business account.
Annual Report, $75, due before the first day of your anniversary month every year — miss it and Illinois can administratively dissolve your LLC.
Northwest handles all five steps above and includes your Illinois registered agent free for year one.
Wrong entity designator, missing registered agent info, and name conflicts account for most bounced filings. Here's what changes with a formation service handling it.
| What matters | Filing it yourself | Using a formation service |
|---|---|---|
| Time spent | 3–5 hours of research + filing | ~10 minutes |
| Total cost | $150 state fee only | $150 state fee + service fee |
| Registered agent | Separate purchase, $100–$300/yr | Often included year one |
| Compliance reminders | You track manually | Automated deadline alerts |
| Rejection risk | Common on first attempt | Reviewed before submission |

"Filed on a Monday, approved about a week and a half later. Didn't expect the registered agent to already be set up when the confirmation came through."
"I tried filing myself first and got rejected over the entity name format. Second time, went through a service and it was fixed before submission."
"Didn't realize the Annual Report deadline landed before my anniversary month even started, not on it. The reminder email caught it in time."
