How to Dissolve an Illinois LLC: Step-by-Step Filing Guide

Closing an Illinois LLC is more than stopping business activity. You also need to wind down obligations, file the correct termination document, and keep a clean record of the process. If the company was formed in Illinois and you want to end its legal existence, the state’s formal filing is the Statement of Termination, Form LLC-35.15.

This guide explains how to dissolve an Illinois LLC, what the Secretary of State expects, and how to avoid the mistakes that can create delays or leave the company in an unresolved state.

What Dissolving an Illinois LLC Actually Means

Dissolving an LLC ends the business’s legal life after its affairs are wrapped up. That is different from simply stopping operations. If you stop taking on new work but never file the proper state paperwork, the LLC can remain active on state records and continue to have compliance obligations.

A proper dissolution generally includes:

• Confirming the members or managers have approved the shutdown according to the operating agreement and state law
• Winding up business affairs
• Paying or resolving company debts and obligations
• Filing the state termination form
• Keeping the filed record and other closing documents for future reference

If you are closing an Illinois LLC because you are starting a new venture, a clean dissolution can help you separate the old business from the new one.

Illinois Requirements Before You File

Illinois does not treat dissolution as an informal shutdown. The Secretary of State requires the LLC to meet specific conditions before the termination can be filed.

According to the state’s instructions, the LLC must be in good standing. An LLC cannot terminate if it has been administratively dissolved, revoked, merged, converted, domesticated, or expired.

In addition:

• The termination must be executed by a manager or another person authorized by the company
• The filing must include the company name and a mailing address for process service
• The filing fee for Form LLC-35.15 is $5
• If you file online, a payment processor fee applies
• If you file the paper form, the state form instructions call for submission in duplicate and payment by check payable to the Secretary of State

Illinois also notes that expedited service requests must be made in person in the Springfield or Chicago office.

Step 1: Review the Operating Agreement and Internal Approval Rules

Before you file anything with the state, check the operating agreement. Many LLCs spell out how a dissolution vote must be approved, how assets are distributed, and who has authority to sign state filings.

If the operating agreement does not address dissolution in detail, document the decision carefully. Your internal records should show:

• Who approved the shutdown
• When the approval occurred
• Whether the company is winding up voluntarily or because the business purpose ended
• Who is authorized to sign the filing

This step matters because the state filing must be signed by someone with authority.

Step 2: Wind Up the Business Before Filing

Dissolution is not just a filing event. It is a closing process.

Before you submit the Statement of Termination, make sure you have handled the company’s practical shutdown tasks:

• Stop taking on new business that could create additional obligations
• Notify vendors, contractors, customers, and other parties as needed
• Collect outstanding receivables
• Pay or negotiate final debts
• Cancel recurring services and subscriptions that belong to the business
• Close or prepare to close business bank accounts after all transactions clear
• Preserve important records, contracts, and tax documents

The cleaner the windup, the less likely you are to leave loose ends behind after the state filing is complete.

Step 3: Prepare Form LLC-35.15, Statement of Termination

Illinois publishes Form LLC-35.15 for a domestic LLC termination. The form is short, but every field matters.

The statement requires:

• The LLC name
• A mailing address where process served on the Secretary of State can be mailed
• A statement that the limited liability company has been terminated
• The signer’s affirmation, under penalties of perjury, that the filing is true, correct, and complete
• The date, signature, name, and title of the person signing

Because the form is a legal filing, make sure the company name matches the state’s records exactly. Small errors in the legal name can create avoidable processing issues.

Step 4: Choose How You Will File

Illinois provides an online LLC termination/withdrawal filing page, and the state also publishes the paper Statement of Termination form.

If you file online:

• Payment must be made with Visa, Mastercard, Discover, or American Express
• A payment processor fee is assessed
• The state says a link will be provided on the receipt page and confirmation email so you can print the filed document
• The online system discourages opening multiple tabs and using autofill because those actions can increase input errors

If you use the paper form:

• The published form instructs filers to submit the document in duplicate
• Payment may be made by check payable to the Secretary of State
• The form is intended to be typed or printed clearly

If you need expedited service, Illinois says the request must be made in person in Springfield or Chicago.

Step 5: File and Keep the Confirmation

Once the filing is submitted, do not treat the process as finished until you have the final proof of filing.

Keep:

• The confirmation page or filed copy
• The receipt email or transaction record
• A copy of the submitted form
• Internal meeting notes or written approval for the dissolution
• Records showing how the business was wound up

These documents can be useful if a bank, tax authority, former vendor, or future owner needs proof that the LLC was properly terminated.

What to Watch for After Filing

Even after the state accepts the filing, you still need to complete the business shutdown.

Focus on the following areas:

• Final accounting and bookkeeping
• Final tax filings, if applicable
• Closing business accounts
• Ending business licenses, permits, subscriptions, and registrations that are no longer needed
• Preserving records in case the company’s history is questioned later

The exact tax and accounting steps depend on the company’s situation, so it is smart to coordinate with your accountant or tax professional before and after the filing.

Dissolution vs. Administrative Dissolution

A voluntary dissolution is a planned shutdown. Administrative dissolution is different. It usually happens when a company fails to stay compliant with state obligations.

That distinction matters because a voluntary termination is cleaner, faster to explain, and easier to document.

To avoid administrative issues:

• Keep the LLC in good standing before you file the termination
• Do not assume that stopping operations ends the company automatically
• Do not ignore state notices or filing obligations while the company is still active on the state’s records

If the entity is already administratively dissolved or revoked, it may not be eligible to file a termination in the same way as a company that is still in good standing.

Common Mistakes to Avoid

Illinois LLC owners often run into problems when they move too quickly or skip the windup process.

Common mistakes include:

• Filing before the LLC is eligible to terminate
• Missing the authorized signer requirement
• Using an incorrect company name on the form
• Forgetting to keep a mailing address for process service on the filing
• Treating the dissolution filing as the only closing step
• Failing to retain proof of filing
• Confusing dissolution of a domestic LLC with withdrawal of a foreign LLC

A careful checklist prevents most of these issues.

When You Might Need a Different Filing

Not every company that ends operations should file the same document.

For a domestic Illinois LLC, the termination filing is Form LLC-35.15, Statement of Termination.

If your company is a foreign LLC authorized to do business in Illinois, the correct closing filing may be a withdrawal rather than a domestic termination. The right filing depends on how the entity was originally formed and registered.

If you are not sure which path applies, confirm the entity type before you submit the filing.
