If you filed Form 966 late, or haven’t filed it at all, the good news is that there is no specific dollar penalty in the Internal Revenue Code tied to a late Form 966 filing. The often-repeated $10-per-day, $5,000-maximum penalty comes from IRC Section 6652, and that penalty applies to exempt organization termination returns filed under Section 6043(b), not to the corporate dissolution returns filed under Section 6043(a).1Office of the Law Revision Counsel. 26 USC 6652 – Failure to File Certain Information Returns, Registration Statements, Etc. No subsection of Section 6652 references Section 6043(a). That said, a late Form 966 still carries real consequences: administrative friction with the IRS, potential criminal exposure for willful failure to file, and transferee liability that can reach shareholders and officers personally after the corporation is gone. File the form as soon as you can, and if the IRS assesses anything, reasonable cause relief is the path.
The Deadline You Missed
Form 966 is due within 30 days of the date the board or shareholders formally adopt a resolution or plan to dissolve the corporation or liquidate any of its stock.2eCFR. 26 CFR 1.6043-1 – Return Regarding Corporate Dissolution or Liquidation The clock runs from the vote, not from when the actual winding down finishes, and it doesn’t stretch just because the liquidation will take years to complete.
If you’re past that 30-day window, file anyway. A late Form 966 is far better than none. The IRS will still process it, and having the notification on file reduces the chance of complications when the final corporate return arrives.
What Late Filing Actually Costs You
The absence of a codified civil penalty for late Section 6043(a) returns is not the same as the absence of consequences. Four things can happen, and they range from mild to serious.
Administrative Friction on the Final Return
The IRS expects Form 966 to arrive before the final corporate tax return. When it doesn’t, there’s a mismatch in the agency’s records. Your final Form 1120 or 1120-S is more likely to draw scrutiny, processing can be delayed, and the IRS may send notices requesting the unfiled form. That starts a back-and-forth that eats time when you’d rather be closing the books.
Criminal Exposure for Willful Failure
Revenue Ruling 65-80 addresses failure to file Form 966 and notes that while the omission does not nullify a liquidation’s tax treatment, it could expose the corporation to criminal penalties for willful failure to file a required return. In practice the IRS almost never pursues criminal charges over a missed Form 966 alone. Willful disregard of the filing obligation, though, sits in a different risk category than missing the deadline by a few weeks because a filing was overlooked.
Transferee Liability After the Corporation Is Gone
Once a corporation dissolves and distributes its remaining assets, the IRS cannot collect from an entity that no longer exists. Under IRC Section 6901 the agency can instead pursue transferee liability against shareholders, officers, or directors who received distributions from the dissolved corporation, reaching unpaid taxes, penalties, and interest.3Internal Revenue Service. IRM 4.11.52 – Transferee Liability Cases The liability is generally capped at the value each person received, but the mechanism means tax problems from the dissolution period can follow individuals personally long after the entity is closed.
What Late Filing Does Not Do
If you’re liquidating a subsidiary under Section 332, failing to file Form 966 on time does not disqualify the transaction from nonrecognition treatment. Revenue Ruling 65-80 addressed this directly, holding that the Form 966 filing is administrative rather than a condition for tax-free treatment. The genuine risk in multi-year Section 332 liquidations sits with Form 952, which waives the statute of limitations on assessment; failing to file Form 952 for all years within the liquidation period can result in the IRS denying nonrecognition treatment.4Office of the Law Revision Counsel. 26 US Code 6043 – Liquidating, Etc., Transactions
Requesting Penalty Relief If the IRS Assesses One
If a notice does show up assessing a penalty tied to your late Form 966, the primary route to relief is a reasonable cause request.
The Reasonable Cause Standard
The IRS will remove or reduce a penalty if you can show that the failure to file on time was due to reasonable cause and not willful neglect. The test is whether you exercised ordinary business care and prudence but were still unable to comply, and the agency evaluates each case on its own facts.5Internal Revenue Service. Penalty Relief for Reasonable Cause
Circumstances that typically support a reasonable cause argument include:
- Death or serious illness of the person responsible for the corporation’s tax filings during the filing window.
- Fire, natural disaster, or other disturbance that destroyed or blocked access to corporate records.
- Inability to obtain the information needed to complete the form despite reasonable efforts.
- Good-faith reliance on a tax professional who gave incorrect guidance about the filing requirement or the deadline.6Internal Revenue Service. IRM 20.1.1 – Introduction and Penalty Relief
The list is not exclusive. Any explanation showing you acted responsibly but couldn’t meet the deadline can qualify. What the IRS looks for is a story that matches the specific dates and events, documentation to back it up, and evidence that you filed as soon as the obstacle was removed.
How to Submit the Request
You can call the number shown on the penalty notice; phone requests are sometimes accepted without written documentation. You can also submit a written request or file Form 843, Claim for Refund and Request for Abatement.7Internal Revenue Service. Administrative Penalty Relief A written submission gives you room to lay out the facts and attach supporting documents, which helps when the circumstances are complex. Include the corporation’s EIN, the specific penalty being contested, the tax period involved, and a detailed explanation.
Why First Time Abatement Usually Won’t Help
The First Time Abatement waiver that the IRS commonly grants for late income tax returns and late deposits generally does not apply to event-based filing requirements like Form 966.7Internal Revenue Service. Administrative Penalty Relief Reasonable cause is the more reliable path.
Filing the Late Form 966 Correctly
When you send the late form in, get the substantive requirements right so the IRS doesn’t treat it as incomplete on top of being late. The form asks for the corporation’s Employer Identification Number, the date and place of incorporation, and the IRS service center where the corporation filed its most recent income tax return.8Internal Revenue Service. Form 966 – Corporate Dissolution or Liquidation It also asks for the date the dissolution resolution or plan was adopted and the last month, day, and year of the corporation’s final tax year.
You must attach a certified copy of the resolution or plan. A board resolution approving dissolution typically works, but it needs to be certified. Filing without the certified copy attached can lead the IRS to treat the submission as incomplete.2eCFR. 26 CFR 1.6043-1 – Return Regarding Corporate Dissolution or Liquidation
Form 966 must be mailed to the IRS service center where the corporation files its income tax return. The correct address depends on the state where the corporation is headquartered, so check the current Form 966 instructions.8Internal Revenue Service. Form 966 – Corporate Dissolution or Liquidation The form cannot be filed electronically; the IRS excludes it from the e-file system for corporate returns, so you have to print, sign, and mail it.9Internal Revenue Service. Tax Year 2022 Directions for Corporations to E-file Use certified mail or a private delivery service that provides proof of the mailing date, especially since you’re already past the deadline and the mailing date will matter if the IRS later questions when the filing was made.
State Dissolution Is Separate
Filing Form 966 with the IRS does not dissolve your corporation at the state level, and filing articles of dissolution with your state does not satisfy the federal Form 966 requirement. Both are required. Most states require articles or a certificate of dissolution filed with the secretary of state, and neglecting the state filing can leave the corporation in active status, triggering ongoing franchise tax or annual report obligations even though the business has stopped operating.
