How to Dissolve a Corporation in Illinois: Filings, Taxes, and Creditors

To dissolve a corporation in Illinois, you need shareholder authorization, a filed Form BCA 14.30 with the Secretary of State, and a careful wind-up that pays creditors, closes tax accounts, and distributes what’s left to shareholders. The state filing fee is only five dollars.1Justia Law. Illinois Code Chapter 805 Act 5 – Article 15 Fees, Franchise Taxes and Charges The work around it takes longer, and skipping pieces can leave directors and shareholders personally on the hook for years.

Check That Your Corporation Is in Good Standing

The Secretary of State will reject a dissolution filing from a corporation that isn’t current. Before anything else, look up your corporation in the Secretary of State’s online business database. Every outstanding annual report has to be filed, and every fee owed has to be paid.

Illinois repealed its corporate franchise tax effective in 2025, with the statutory provisions fully removed as of January 1, 2026.2Illinois General Assembly. HB5490 103rd General Assembly Franchise tax isn’t a going-forward concern, but if your corporation owes unpaid franchise taxes from years before the repeal, those still need to be resolved before the state processes your dissolution.

If the Secretary of State already administratively dissolved your corporation for noncompliance, you’ll need to reinstate it before you can voluntarily dissolve. Reinstatement means submitting an application with all overdue reports and paying the outstanding fees and penalties.3Justia Law. Illinois Code Chapter 805 Act 5 – Article 12 Dissolution and Remedies

Authorize the Dissolution

Illinois law gives you two ways to authorize a voluntary dissolution.

Board Resolution and Shareholder Vote

The usual route: the board of directors adopts a resolution proposing dissolution and directing the question to a shareholder vote at an annual or special meeting. Shareholders must approve by at least a two-thirds vote of all outstanding shares entitled to vote, unless the articles of incorporation set a different threshold, which can’t be lower than a simple majority.3Justia Law. Illinois Code Chapter 805 Act 5 – Article 12 Dissolution and Remedies

Unanimous Written Consent

If every shareholder entitled to vote signs off in writing, you can skip both the board resolution and the meeting. No director action is required at all.3Justia Law. Illinois Code Chapter 805 Act 5 – Article 12 Dissolution and Remedies For a corporation with just a handful of shareholders, this is almost always the fastest path.

File the Articles of Dissolution

Once the dissolution is authorized, prepare Form BCA 14.30, Articles of Dissolution, and file it with the Secretary of State’s Department of Business Services. The form asks for:

  • The exact corporate name as it appears on the original articles of incorporation. A missing comma or an abbreviated word can trigger a rejection.
  • The date the board and shareholders (or the shareholders alone, under unanimous consent) approved the dissolution.
  • The total shares outstanding and the total that voted in favor. If unanimous written consent was used, that gets indicated on the form.

Submit by mail to the Department of Business Services in Springfield, or through the Secretary of State’s online filing system. The fee is five dollars.1Justia Law. Illinois Code Chapter 805 Act 5 – Article 15 Fees, Franchise Taxes and Charges Online filings typically process within a few business days; mailed filings can take several weeks. Once approved, the Secretary of State issues a Certificate of Dissolution.

Close Out Federal Taxes

Form 966 Within 30 Days

Within 30 days of adopting the resolution or plan to dissolve, file IRS Form 966 (Corporate Dissolution or Liquidation). If you later amend the resolution, another Form 966 is due within 30 days of the amendment.4Internal Revenue Service. Form 966 Corporate Dissolution or Liquidation The clock starts when shareholders authorize the dissolution, not when the state processes your filing, so prepare Form 966 alongside your Articles of Dissolution.

Final Form 1120

File a final federal income tax return on Form 1120 for the corporation’s last tax year and check the “final return” box. Pay any taxes owed. The IRS won’t close the account until returns are filed and taxes are paid.

Close the EIN

To close the corporation’s EIN account, send a letter to the IRS with the full legal name of the business, the EIN, the business address, and the reason for closing. Include a copy of the original EIN assignment notice if you still have it. Mail to the IRS in Cincinnati, OH 45999.5Internal Revenue Service. Closing a Business

Final IL-1120

File a final Form IL-1120 with the Illinois Department of Revenue and check the “final return” box in Step 1, Line C. The due date matches the federal one: generally the 15th day of the fourth month after the close of the tax year.6Illinois Department of Revenue. IL-1120 Instructions

A dissolving corporation can request a prompt determination of its tax liability from the Department of Revenue. When the request is properly made after the final return has been filed, the statute of limitations (absent fraud) will not extend beyond 18 months from the date of the request.6Illinois Department of Revenue. IL-1120 Instructions That can spare shareholders from a surprise assessment years down the line.

Sales Tax, Withholding, and Other Accounts

Close every open Illinois tax account. That means sales tax, withholding tax, and anything else the corporation was registered for. You can do it through MyTax Illinois, by calling 217-785-3707, or by visiting a regional office. Check the “final return” box on each final return you file.7Illinois Department of Revenue.

Unemployment Insurance

If the corporation had employees, close its unemployment insurance account with the Illinois Department of Employment Security through MyTax Illinois or by filing a Notice of Change form (UI-50).8Illinois Department of Employment Security. Business Updates

Take Care of Employees

Final Paychecks

Under the Illinois Wage Payment and Collection Act, pay all final compensation at the time of separation if you can, and no later than the next regularly scheduled payday. Final compensation covers wages, earned commissions, earned bonuses, and the cash value of any earned but unused vacation. Illinois law prohibits any policy that forces employees to forfeit earned vacation on separation.9Justia Law. Illinois Code 820 ILCS 115 – Illinois Wage Payment and Collection Act

Advance Notice of Closing

The Illinois WARN Act requires employers with 75 or more full-time employees to give 60 days’ written notice of a plant closing or mass layoff to affected employees, their representatives, and state and local officials.10Illinois Department of Labor. Worker Adjustment and Retraining Notification Act (WARN) Below 75 full-time employees, the Illinois WARN Act doesn’t apply, though the federal WARN Act may still reach employers with 100 or more.

Notify Creditors and Pay Debts Before Shareholders

After the Certificate of Dissolution is issued, the corporation’s legal existence ends for new business. It can still do what’s needed to wind up: collect what it’s owed, settle its obligations, and distribute anything left to shareholders.3Justia Law. Illinois Code Chapter 805 Act 5 – Article 12 Dissolution and Remedies

Send written notice to every known creditor and claimant within 60 days of the effective date of dissolution. The notice must set a deadline (at least 120 days from the effective date) by which creditors must submit their claims. A creditor who misses that deadline loses the right to pursue the claim against the corporation, its directors, officers, or shareholders.3Justia Law. Illinois Code Chapter 805 Act 5 – Article 12 Dissolution and Remedies Failing to notify a known creditor can leave directors and shareholders personally exposed, so treat this step carefully.

Pay debts in the correct order. All liabilities, including taxes, employee wages, and creditor claims, come before any distribution to shareholders. Only after every obligation is cleared can remaining property go to shareholders in proportion to their ownership.3Justia Law. Illinois Code Chapter 805 Act 5 – Article 12 Dissolution and Remedies Distributing to shareholders before the debts are paid can create personal liability for the shareholders who took the money.

The Five-Year Exposure Window and Records

Dissolution doesn’t wipe out claims that already exist. Any civil suit that could have been brought against the corporation, its directors, or its shareholders for a right or liability existing before or at dissolution can still be filed for up to five years after the dissolution date. The corporation can sue and be sued in its own name during that period.11Illinois General Assembly. Illinois Code 805 ILCS 5/12.80 – Survival of Remedy After Dissolution The five-year window doesn’t extend a shorter statute of limitations; it just prevents dissolution itself from cutting off an existing claim.

Because suits can arrive years later and the IRS can audit past returns, hold onto the paperwork. Keep federal and state tax returns and supporting financial records for at least seven years. Keep corporate formation documents, board and shareholder resolutions (especially the dissolution authorization), and any contracts with ongoing obligations indefinitely.
