Form 966 is a one-page IRS notice that a corporation files after its board or shareholders adopt a resolution or plan to dissolve or liquidate any of the company’s stock. The filing is due within 30 days of that resolution, and it must be mailed on paper to the IRS service center where the corporation files its income tax return, with a certified copy of the resolution attached. The filing requirement comes from 26 U.S.C. § 6043(a).1Office of the Law Revision Counsel. 26 USC 6043 – Liquidating, Etc., Transactions It puts the IRS on notice that the company is winding down. It does not, by itself, dissolve the corporation, settle any tax debt, or close the EIN.
Who Has to File
Any corporation that adopts a resolution or plan to dissolve or liquidate all or part of its capital stock files Form 966. That covers C corporations filing Form 1120 and S corporations filing Form 1120-S. A subsidiary being liquidated into its parent still has to file; the Treasury regulations say so directly.2eCFR. 26 CFR 1.332-6 Records to Be Kept and Information to Be Filed With Return
Two groups do not file it. Tax-exempt organizations under Section 501 use the instructions for Form 990 or Form 990-PF instead. Qualified subchapter S subsidiaries (QSubs) follow Form 8869.3IRS.gov. Form 966 (Rev. October 2016) – Corporate Dissolution or Liquidation
If the corporation is being wound up in bankruptcy, the receiver, trustee, or assignee handling its affairs signs and files the form instead of a corporate officer.3IRS.gov. Form 966 (Rev. October 2016) – Corporate Dissolution or Liquidation
The 30-Day Deadline
The clock starts the day the board or shareholders formally adopt the resolution or plan.1Office of the Law Revision Counsel. 26 USC 6043 – Liquidating, Etc., Transactions From that date, you have 30 days to get Form 966 to the IRS. The window does not run from the day assets start being distributed, and it does not run from the day the state paperwork is filed. It runs from adoption. That trips up owners who assume the federal notice can wait until state dissolution is finalized.
If the plan is later amended or supplemented, a second Form 966 is due within 30 days of that amendment, referencing the original filing date and attaching a certified copy of the amendment.4eCFR. 26 CFR 1.6043-1 Return Regarding Corporate Dissolution or Liquidation
What the Form Asks For
The form itself is short, but it wants specific information and a mandatory attachment:
- The corporation’s legal name, mailing address (including any suite, unit, or P.O. box), and Employer Identification Number.
- The date and state or jurisdiction of original incorporation.
- Whether the return type is Form 1120 or Form 1120-S.
- Whether the liquidation is complete or partial.
- The exact date the resolution or plan was adopted. This is the date the IRS uses to check the 30-day window, so accuracy matters.
- The total number of common and preferred shares outstanding when the plan was adopted.
- The Internal Revenue Code section the corporation is dissolving under. Most standard dissolutions cite Section 331. A subsidiary liquidation qualifying for nonrecognition treatment cites Section 332.
You must attach a certified copy of the resolution or plan, along with any amendments or supplements not previously filed.3IRS.gov. Form 966 (Rev. October 2016) – Corporate Dissolution or Liquidation Without the resolution, the IRS has no way to verify what the shareholders or board actually authorized.
How to File It
Form 966 is paper only. The IRS does not accept it electronically, and it should not be bundled into an e-filed corporate income tax return.5Internal Revenue Service. Tax Year 2022 Directions for Corporations to E-File Mail it to the IRS service center where the corporation normally files its income tax return.3IRS.gov. Form 966 (Rev. October 2016) – Corporate Dissolution or Liquidation
The IRS does not send back a confirmation of receipt. Because the 30-day deadline is strict, certified mail with a return receipt is worth the small extra cost; it becomes your proof of timely filing if the timeline is later questioned. Keep the stamped receipt, a copy of the completed form, and the attached resolution in the corporation’s permanent records.
What Happens If You Don’t File
The penalty picture is narrower than some sources suggest. Section 6043(d) lists specific penalty cross-references for failures under subsections (b) and (c) of the statute, but not for subsection (a), which is the provision that requires Form 966.1Office of the Law Revision Counsel. 26 USC 6043 – Liquidating, Etc., Transactions The $500-per-day, $100,000-cap penalty that gets cited in some guides applies to failures under § 6043(c), which covers changes in corporate control and recapitalizations, not dissolution notices.6Office of the Law Revision Counsel. 26 USC 6652 – Failure to File Certain Information Returns, Registration Statements, Etc.
Skipping it still causes real problems. Without Form 966, the IRS has no record the corporation is winding down. Its systems keep expecting annual returns, and when those returns don’t come, the agency generates automated notices and can assess failure-to-file penalties under Section 6651. Cleaning that up after the assets are gone and the officers have moved on is slow work, often requiring professional help.
The Other Filings That Come With Dissolution
Form 966 is the opening step. Several other filings need to follow, or the corporation’s account stays open and the notices keep coming.
Final Income Tax Return
The corporation files a final Form 1120 or 1120-S with the “Final return” box checked under Item E. A dissolved corporation generally files this by the 15th day of the fourth month after the date of dissolution.7Internal Revenue Service. Instructions for Form 1120 (2025) The return reports income, deductions, and any gain or loss on liquidating distributions through the dissolution date.
Final Employment Tax Returns
If the corporation had employees, it files a final Form 941 (or Form 944) for the quarter in which the last wages were paid, checking the box that the business has closed and entering the date of the final paycheck. It also files a final Form 940 for unemployment tax with box “d” checked.8Internal Revenue Service. Closing Your Business Employment tax filings get overlooked more than any other piece, especially when payroll stopped months before the formal dissolution.
Reporting Distributions to Shareholders
The corporation files Form 1099-DIV for each person receiving $600 or more in liquidating distributions. Cash goes in Box 9 and noncash distributions go in Box 10 at fair market value on the distribution date. These are reported separately from ordinary dividends, not in Box 1a or 1b.9Internal Revenue Service. Instructions for Form 1099-DIV
Closing the EIN Account
Filing the final returns does not close the EIN. Send a letter to the IRS in Cincinnati, OH 45999 with the corporation’s legal name, EIN, address, and the reason for closing the account. Include a copy of the EIN assignment notice if you still have it. The IRS will not close the account until all required returns are filed and all taxes are paid.8Internal Revenue Service. Closing Your Business
Personal Liability for Unpaid Payroll Taxes
The largest personal risk during a dissolution is the Trust Fund Recovery Penalty. Under IRC § 6672, any person responsible for collecting and paying over the income tax and employee share of FICA withheld from paychecks can be held personally liable for 100% of the unpaid amount if the failure was willful. The liability follows the individual, not the corporation.10Internal Revenue Service. 8.25.1 Trust Fund Recovery Penalty (TFRP) Overview and Authority Officers who distribute assets to shareholders before settling payroll tax obligations are the usual targets. Filing Form 966 and the final employment returns on schedule builds the paper trail that limits this exposure.
Form 966 Does Not Dissolve the Corporation Under State Law
This is worth stating plainly because the misconception is common. Form 966 notifies the IRS for federal tax purposes. It does nothing to end the corporation’s legal existence.11IRS.gov. About Form 966, Corporate Dissolution or Liquidation To actually terminate the entity, you file articles of dissolution (sometimes called a certificate of dissolution) with the Secretary of State where the corporation was incorporated.
Most states also require a creditor claim window, typically 90 days to six months, before finalizing the dissolution. Many states require a tax clearance certificate from the state revenue department before accepting the filing. If the corporation is registered to do business in other states, each of those states usually requires separate withdrawal paperwork. Miss the state steps and the corporation keeps existing on paper, accruing annual report fees, franchise taxes, and late penalties long after it has stopped operating.
