Dissolving a Delaware LLC vs a Delaware C-Corp: Key Differences

If you own a Delaware company and are deciding how to close it, the entity type determines almost everything about the process: who approves it, what you file, what Delaware charges before it lets you leave, and how the IRS taxes the money that comes out at the end.

The two processes run in opposite orders. A Delaware C-Corp files its Certificate of Dissolution first and then winds up its affairs, with the corporation continuing to exist for three years afterward for that purpose. A Delaware LLC winds up first and files its Certificate of Cancellation only once winding up is complete, at which point it ceases to exist. On the tax side, a C-Corp's liquidation is a taxable event at both the company and shareholder level, while an LLC taxed as a partnership or disregarded entity generally passes its final-year results straight through to its owners.

Below is how the two compare at each stage, and where the differences cost owners time or money.

The filing order is reversed

This is the difference that shapes the rest.

C-Corp: dissolve, then wind up. Under the Delaware General Corporation Law, the corporation files a Certificate of Dissolution once dissolution is authorized. The filing makes the dissolution effective. The corporation then continues to exist for three years (or longer if the Court of Chancery directs) for the purpose of prosecuting and defending suits, settling its affairs, disposing of property, and distributing remaining assets.

LLC: wind up, then cancel. Under the Delaware LLC Act, dissolution happens when a dissolution event occurs, such as a member vote. The LLC then winds up while it still exists. Only after winding up is complete does it file a Certificate of Cancellation, which ends its existence.

The practical effect is that a C-Corp can make its dissolution public on day one and work through its obligations afterward, while an LLC's public filing comes at the end. An LLC that files its Certificate of Cancellation before it has actually finished winding up has filed a certificate that is not accurate, and the cancellation does not protect its members from claims that should have been provided for.

Approval thresholds come from different sources

C-Corp. The board of directors adopts a resolution recommending dissolution, and holders of a majority of the outstanding voting stock approve it. Alternatively, dissolution can be authorized without board action if all stockholders entitled to vote consent in writing. The company's charter and any stockholder or investor agreements can impose additional requirements, and venture-backed companies frequently have protective provisions that give preferred stockholders a separate vote on dissolution.

LLC. The LLC agreement controls. If it is silent, the Delaware LLC Act's default rule applies: dissolution is approved by members holding more than two-thirds of the then-current profit interests in the LLC. Because LLC agreements are drafted with wide latitude, the actual threshold varies more from company to company than it does for corporations.

In both cases, the approval should be documented in writing and kept with the company's records. For a C-Corp, the date of the board resolution also starts the federal Form 966 deadline.

Delaware's state tax works differently for each

Delaware will not accept either filing while state taxes are outstanding, but the taxes themselves are structured differently.

C-Corp franchise tax. Before Delaware will file a Certificate of Dissolution, the corporation must file all outstanding annual franchise tax reports and pay franchise taxes and fees through the end of the calendar year in which the certificate is filed. A corporation dissolving in January pays the full year.

The amount depends on the calculation method. Delaware's default bill uses the authorized shares method, which can produce very large figures for companies that authorized millions of shares. Most startups pay far less by recalculating under the assumed par value capital method, which uses the company's gross assets and issued shares. A corporation that receives an unexpectedly large franchise tax bill during dissolution should check which method was used before paying it.

LLC annual tax. A Delaware LLC files no annual report. It pays a flat annual tax instead, and the tax for the year in which cancellation becomes effective must be paid before Delaware will accept the Certificate of Cancellation. Past-due years must also be paid, along with penalties and interest.

For most small entities, the LLC's flat tax is simpler to clear. For a corporation, the franchise tax calculation is the step most worth checking before filing.

Creditor rules overlap but are not identical

Both entities have to pay their creditors, or make reasonable provision for them, before distributing anything to owners.

C-Corp. The DGCL offers a formal, optional notice procedure under which the corporation sends notice to known claimants, sets deadlines for claims, and can seek court approval of the amount it reserves. Following it gives directors and stockholders stronger protection from later claims. A corporation that does not use the formal procedure must still adopt a plan of distribution that makes reasonable provision for known, pending, and reasonably likely future claims.

LLC. The LLC Act requires the LLC to pay or make reasonable provision for known claims, pending claims, and claims likely to arise or become known within ten years after dissolution. A member who receives a distribution while creditors were not properly provided for can be required to return it.

In practice, a company with real contingent liabilities (pending litigation, open warranties, lease obligations) needs more care in either form. The C-Corp's court-approved route is more formal and takes longer, but offers more certainty.

The federal tax treatment differs at the core

C-Corp liquidation is taxed twice. The corporation files Form 966 within 30 days of adopting its plan of dissolution and a final Form 1120 for its last short tax year. Property the corporation distributes to shareholders in liquidation is treated as if it had been sold at fair market value, so appreciated assets can create taxable gain on the final return. Shareholders then treat their liquidating distributions as payment in exchange for their stock, reported to them on Form 1099-DIV, and recognize their own gain or loss against their basis. The corporation's net operating losses and unused credits end with it.

LLC liquidation usually passes through. An LLC taxed as a partnership files a final Form 1065 and issues final Schedule K-1s. Distributions to members are generally not taxable to the extent they do not exceed the member's basis in their interest, and losses flow through to the members' own returns. A single-member LLC taxed as a disregarded entity reports its final year directly on its owner's return. There is no Form 966 and no entity-level tax on distributions, unless the LLC elected to be taxed as a corporation, in which case it follows the corporate rules.

Foreign ownership adds filings to both. A C-Corp that is 25% or more foreign-owned files Form 5472 with its final Form 1120. A single-member LLC wholly owned by a foreign person files a final pro forma Form 1120 with Form 5472. The $25,000 penalty for a missing Form 5472 applies to the final year in either structure.

Outstanding registrations in other states don't close themselves

This applies to both. A Delaware entity registered to do business in another state, because it had an office or employees there, files a withdrawal and a final state return in that state. Dissolving or canceling in Delaware does not withdraw the registration elsewhere, and withdrawing elsewhere does not end the entity in Delaware. Each state continues to assess its own annual fees and minimum taxes until its own filing is made.

Undoing the decision is handled differently

C-Corp. A dissolved corporation can revoke its dissolution at any time within three years after dissolution (or a longer period the Court of Chancery directs) by filing a certificate of revocation of dissolution, after approval by the board and stockholders.

LLC. Dissolution can be revoked during winding up, before the Certificate of Cancellation is filed, with the approval the LLC Act and LLC agreement require. Once the Certificate of Cancellation is filed, the LLC has ceased to exist, and the revocation route is no longer available.

The bottom line

The entity type decides the sequence: a C-Corp files first and winds up afterward, while an LLC winds up first and files only when it is finished. A C-Corp's costs tend to concentrate in the franchise tax calculation and the two levels of federal tax on its liquidation, while an LLC's concentrate in getting the winding up genuinely complete before it cancels, since cancellation ends the entity outright. Before choosing a timeline for either, check the governing documents for the approval threshold, the state tax position in Delaware and every other state of registration, and which federal information returns the company has been filing.

Frequently asked questions

What is the difference between a Certificate of Dissolution and a Certificate of Cancellation in Delaware?

A Certificate of Dissolution is filed by a corporation and begins its dissolution, after which the corporation winds up while it continues to exist for three years. A Certificate of Cancellation is filed by an LLC after it has dissolved and completed winding up, and it ends the LLC's existence on filing.

Is it cheaper to dissolve a Delaware LLC or a Delaware C-Corp?

The Delaware filing fees for both are modest. The larger cost difference usually comes from state tax and federal tax. A C-Corp pays franchise tax through the end of the year it dissolves and faces corporate-level tax on any appreciated assets it distributes, while an LLC pays a flat annual tax and usually passes its final-year results through to its owners.

Does a Delaware LLC need to file Form 966 when it dissolves?

Only if the LLC elected to be taxed as a corporation. An LLC taxed as a partnership files a final Form 1065, and a single-member LLC taxed as a disregarded entity reports its final year on its owner's return. Neither files Form 966.

Who has to approve dissolving a Delaware C-Corp?

By default, the board of directors adopts a dissolution resolution and holders of a majority of the outstanding voting stock approve it, or all voting stockholders consent in writing without board action. The charter and investor agreements may add requirements, such as a separate vote of preferred stockholders.

Who has to approve dissolving a Delaware LLC?

Whatever the LLC agreement specifies. If the agreement is silent, Delaware's default rule requires approval from members holding more than two-thirds of the then-current profit interests in the LLC.

Can a dissolved Delaware company be brought back?

A dissolved C-Corp can revoke its dissolution within three years by filing a certificate of revocation of dissolution. An LLC can revoke its dissolution during winding up, but once its Certificate of Cancellation is filed, it no longer exists and cannot revoke the dissolution.
