How to form a
Illinois LLC

The filing, in plain English

A Illinois LLC is created when the Illinois Secretary of State, Department of Business Services accepts your Articles of Organization and issues a certificate. Everything else — the EIN, the operating agreement, the bank account — happens around that central act. Our $299 flat service walks through all of it; you pay the Illinois filing fee of $150 separately, directly to the state.

Most founders forming a single-member Illinois LLC are done in 5–10 business days of standard processing time. Multi-member filings take about the same; the additional complexity lives in the operating agreement, not at the state.

The six steps we take

1. I.

   Confirm your name is available

   We check your chosen LLC name against the Illinois Secretary of State database before anything is submitted. If the first choice is taken, we call before filing — we do not submit a filing you did not authorize.

2. II.

   Draft the Articles of Organization

   A formation specialist prepares the Articles to Illinois's exact format, with your members, registered agent, principal office address, and effective date.

3. III.

   Submit electronically

   Filed through the Illinois Secretary of State's online system. Your Illinois registered agent of record is our Springfield office for the first year.

4. IV.

   Illinois approves the LLC

   Approval typically arrives in 5–10 business days. We watch the queue daily and forward the stamped certificate the moment it clears.

5. V.

   We obtain the EIN

   Once the LLC is approved, we file SS-4 with the IRS to get your Employer Identification Number — the federal tax ID you need to open a business bank account.

6. VI.

   We deliver the bank-ready packet

   Stamped certificate, EIN letter, custom operating agreement drafted to your ownership structure, and your registered agent confirmation. You sign the operating agreement and open the account.

What you need to have ready

Before we file, we need a handful of decisions from you. None of them are heavy, but we have to confirm each one on the reservation call:

• A Illinois LLC name — ending in "LLC," "L.L.C.," or "Limited Liability Company," distinguishable from other Illinois entities.
• A principal office address — home, commercial, or mail-forwarding. Becomes part of the public record.
• Members — the individuals or entities that own the LLC. Illinois allows single-member LLCs.
• Management structure — member-managed (most common) or manager-managed. We draft the operating agreement to match.
• An effective date — either immediately on approval, or a future date if you want a January 1 start for tax reasons.

What's included in the $299 flat fee

The $299 is a flat service fee for everything on our side. Illinois's state filing fee of $150 is paid directly to the Illinois Secretary of State and is the same whether you file with us or on your own. There are no upsells — no basic, plus, or premium tiers. One price, four things.
