What forms does the Illinois Secretary of State provide?

The Illinois SOS maintains the official forms for creating and maintaining business entities: articles or certificates of formation, amendments, annual reports, registered-agent changes, foreign registration, and dissolution. Using the current official Illinois form matters because an outdated or wrong-entity version gets rejected. We file the correct Illinois formation or maintenance form for whatever you need so it is accepted the first time.

Where do I find the right Illinois business form?

On the Illinois Secretary of State's website, but the catalog is large and organized by entity type and action, so it is easy to grab the wrong one. The right form depends on your entity, LLC versus corporation, and exactly what you are changing. Rather than hunt through the Illinois library, we identify and prepare the correct form for your specific situation.

Can I file Illinois business forms online?

Most Illinois filings are available online now, which is faster than mail, though a few documents still require paper or a wet signature. Online filing also reduces rejection from handwriting or formatting. We file your Illinois forms electronically where the state allows and handle the paper exceptions, returning the stamped result to your records.

Why do Illinois filings get rejected?

Usually small things: a name that conflicts or lacks the right designator, a missing registered agent, an unsigned or wrong-version form, or an unpaid fee, and each rejection costs days. We review the Illinois form against the state's requirements before submitting so it clears rather than bouncing back for a fixable error you did not know about.

Do I need to notarize Illinois business forms?

Generally no: most Illinois Secretary of State business filings do not require notarization, just an authorized signature, though a few specific documents or other agencies may. Assuming everything needs a notary slows you down. We tell you which Illinois forms, if any, need more than a signature so you do not add steps that are not required.

How much do Illinois forms cost to file?

Illinois sets a fee per filing type, and it varies by form and entity, with expedited options costing more. Because the figures change, we show the current Illinois fee before filing and pass it through at cost. Our service pricing is on the pricing page rather than quoted here where a number could go stale.

What is the difference between formation and maintenance forms?

Formation forms, the articles or certificate, create the entity; maintenance forms keep it current, annual reports, amendments, agent changes, while closing forms end it. Mixing them up, filing an amendment when you needed an annual report, causes delays. We map which Illinois forms your situation actually calls for so you file the right document.
