How to Close an LLC in Illinois: Steps, Forms, Fees, and Tax Checklist

Closing an Illinois LLC takes more than stopping operations or filing a final tax return. To end the company properly, you need to follow the dissolution process, settle debts, handle state tax obligations, notify the right parties, and file the correct paperwork with the Illinois Secretary of State.

If you skip those steps, the LLC can remain on the state’s records, continue to rack up filing obligations, and create avoidable cleanup work later. A clean wind-down protects the members, reduces compliance risk, and gives the business a formal ending.

This guide walks through how to close an LLC in Illinois, what forms you may need, how much the filing costs, and what to do before and after termination.

What It Means to Dissolve an LLC in Illinois

Dissolving an LLC is the legal process of ending the company’s existence. It is different from simply ceasing to operate. A dissolved company has gone through the required approvals, filed the appropriate termination document, paid outstanding obligations, and wrapped up business affairs.

In Illinois, an LLC must generally be in good standing before it can voluntarily terminate. The Illinois Secretary of State’s instructions state that an LLC cannot terminate or withdraw if it has been administratively dissolved, revoked, merged, converted, domesticated, or expired.

That means the first step is not the filing itself. The first step is confirming that the LLC is eligible to close the way you intend.

When an Illinois LLC Might Need to Close

There are many reasons an LLC may no longer make sense:

• The owner is retiring or moving on to another venture.
• The business never became profitable.
• The members want to form a different entity structure.
• The owners no longer agree on how to operate the company.
• The LLC completed the project or purpose for which it was formed.

Whatever the reason, the closing process should be handled deliberately. A formal shutdown is almost always better than letting the business go dormant.

Step 1: Review the Operating Agreement

Start with the LLC’s operating agreement.

Many operating agreements explain:

• Who can propose dissolution
• What vote threshold is required
• Whether written consent is allowed
• How to distribute remaining assets
• How to handle unresolved debts or liabilities

If the agreement is silent, the members should still document the decision carefully. Good records help prove that the LLC properly approved the closing and can reduce disputes later.

If there is no operating agreement, state law and member consent procedures may control the process. In that situation, it is wise to document every action in writing.

Step 2: Approve the Decision to Dissolve

Once the members agree that the LLC should close, record the approval in formal company records.

Use a meeting resolution, written consent, or member vote, depending on how the company is organized. The records should show:

• The date of the approval
• The names of the approving members or managers
• The percentage or number of votes in favor
• The effective date of dissolution, if applicable

This documentation matters because the company is moving from active operations into wind-up mode. Banks, vendors, landlords, and tax agencies may later ask for proof that the closing was authorized.

Step 3: Stop New Business and Start Winding Up

After approval, the LLC should stop entering new obligations unless they are necessary to complete the wind-up.

Winding up usually includes:

• Completing unfinished work, if needed
• Collecting money owed to the company
• Paying vendors and creditors
• Canceling subscriptions and recurring charges
• Closing business bank accounts after final reconciliation
• Ending leases, service contracts, and insurance policies when possible
• Canceling licenses, permits, and assumed names that are no longer needed

The goal is to convert the company from an operating business into a closed estate of assets and liabilities. Do not distribute remaining funds to members until debts and taxes are handled.

Step 4: Handle Illinois Tax Obligations

Tax compliance is one of the most important parts of closing an LLC.

The Illinois Department of Revenue says that when you decide to close your business, you must contact the department regarding your tax liabilities. It also says that when you file the final tax form for each tax type, you should mark it as a final return when the form allows it.

Depending on how the LLC operated, you may need to address:

• Illinois withholding tax accounts
• Illinois sales tax accounts
• Corporate income tax filings if the LLC elected corporate taxation
• Federal final returns and related closeout filings

If the LLC had employees, Illinois withholding filings may need a final return. If the business collected sales tax, the sales tax account should be closed after the last taxable period is reported. If the LLC was taxed as a corporation, the entity should file the proper final Illinois corporate return.

If your LLC used MyTax Illinois, you may be able to manage part of the closeout process there. For many businesses, it is also helpful to work with a tax professional to make sure every account is closed correctly and no reporting period is missed.

Step 5: File the Correct Illinois Termination Form

The filing you use depends on the type of LLC and how it is registered in Illinois.

For a domestic Illinois LLC, the Secretary of State uses Form LLC-35.15, Statement of Termination. The publication listing for Illinois LLC forms shows a $5 filing fee for this form.

For a foreign LLC that is withdrawing from Illinois, the company generally uses the withdrawal filing instead of a domestic termination form. The Secretary of State’s LLC termination instructions distinguish between termination and withdrawal, and the company must use the correct filing for its status.

The filing can be completed online or by paper, depending on the route you choose. The online instructions note that payment may be made by credit card and that a payment processor fee applies for online transactions. The paper form states that payment by check is accepted and payable to the Secretary of State.

Before filing, make sure the signer is authorized. Illinois says the termination must be executed by a manager or another person authorized by the company.

Step 6: Notify Creditors, Vendors, and Other Stakeholders

An LLC should not quietly vanish. Notice gives creditors and counterparties a chance to submit claims or close out accounts.

Common parties to notify include:

• Vendors and suppliers
• Landlords and property managers
• Lenders and finance companies
• Insurance carriers
• Employees and contractors
• Customers with prepaid balances, warranties, or ongoing service arrangements

If the LLC owes money, settle valid claims or establish reasonable reserves before making distributions to members. That helps avoid disputes and protects against improper wind-up distributions.

Step 7: Close Accounts and Cancel Registrations

Once the core financial obligations are resolved, finish the administrative cleanup.

This often includes:

• Closing the business bank account
• Cancelling debit and credit cards tied to the LLC
• Ending payroll services
• Removing the company from tax accounts that are no longer active
• Canceling local business licenses and permits
• Ending fictitious name registrations, if they are no longer needed

Keep copies of the final statements, confirmations, and filed forms. Even after dissolution, you may need records for tax, banking, or legal reasons.

Step 8: Distribute Remaining Assets

After debts, taxes, and final obligations are handled, any remaining assets can be distributed to the members.

The operating agreement should control the distribution process whenever possible. If there is no agreement or if the agreement is unclear, the members should document how the distribution amount was calculated and why each person received what they did.

Do not rush this step. Premature distributions can create problems if a later claim or tax bill appears.

Common Mistakes to Avoid

Closing an LLC is straightforward when handled in order, but several mistakes come up often:

• Filing the termination form before resolving taxes and debts
• Forgetting to mark final tax returns as final
• Assuming the LLC can just stop operating without a formal filing
• Using the wrong filing for a foreign LLC versus a domestic LLC
• Distributing assets before liabilities are fully resolved
• Failing to keep the records of member approval and final closeout

A careful checklist prevents most of these issues.

Frequently Asked Questions

Can I just stop doing business and ignore the filing?

No. If you want the LLC to end formally, you should follow the Illinois dissolution or withdrawal process. Otherwise, the entity may remain active in state records and continue to have filing or compliance obligations.

How much does it cost to dissolve an Illinois LLC?

For a domestic Illinois LLC, the Secretary of State form listing shows a $5 filing fee for the Statement of Termination. Online filing may also include a payment processor fee.

Do I need to be in good standing?

Yes, for a voluntary termination or withdrawal, Illinois requires the LLC to be in good standing. An LLC that has already been administratively dissolved or revoked generally cannot use the voluntary termination filing.

What if my LLC had employees or collected sales tax?

You should close those tax accounts properly and file any final Illinois returns that apply. The Department of Revenue says to contact it when closing your business and to mark final returns where the form allows it.

Should I keep records after the LLC is closed?

Yes. Keep copies of the dissolution filing, tax filings, final bank statements, member consents, and creditor notices. Those records can matter long after the company is closed.

Final Checklist for Closing an Illinois LLC

Before you consider the LLC closed, make sure you have:

• Reviewed the operating agreement
• Approved dissolution in writing or by vote
• Stopped new business activity
• Paid or addressed debts and liabilities
• Filed all final state and federal tax returns
• Submitted the correct Illinois termination or withdrawal filing
• Notified creditors and stakeholders
• Closed business accounts and permits
