Dissolve a corporation in Colorado

What does dissolving a Colorado corporation involve?

Dissolving a corporation in Colorado means formally ending the company's existence with the Colorado Secretary of State and settling its obligations with the IRS and the Colorado Department of Revenue. It is not the same as halting operations or letting the periodic report lapse. Until the paperwork is filed and the tax accounts are closed, the corporation still exists, still owes its periodic report, and still has open tax accounts.

A corporation carries more formality than an LLC. Where an LLC in Colorado can be dissolved by its members simply, a corporation needs a board resolution and a shareholder voteplus the corporation-specific federal filing, IRS Form 966. The general framework is in the guide to dissolving a corporation; this page covers what is specific to Colorado, chiefly that everything at the Secretary of State is done online.

The steps to dissolve a Colorado corporation, in order

1. Board resolution recommending dissolution and a plan of liquidation.
2. Shareholder approvalrecorded in the minutes or a written consent.
3. File articles of dissolution online with the Colorado Secretary of State.
4. File IRS Form 966 within 30 days of the resolution.
5. Wind up: notify creditors, settle debts, and distribute remaining assets.
6. Close Department of Revenue accounts and file final state returns.
7. File final federal returns and close the IRS business account attached to the EIN.

Board and shareholder approval

The two-step approval distinguishes a corporation from an LLC. The board of directors adopts a resolution recommending dissolution, usually with a plan of liquidation, and then the shareholders vote to approve, generally a majority of the outstanding shares unless the articles or bylaws set a higher bar.

Record both actions in writing. Even a single-shareholder Colorado corporation completes both, the board resolution and the shareholder consent, on paper. The written record keeps the dissolution clean if it is ever questioned, and it fixes the resolution date that starts the Form 966 clock.

Articles of dissolution in Colorado

Colorado requires business filings to be made onlinethe Secretary of State does not take paper for most of them. You file articles of dissolution through the state's business filing system, and processing is typically fast, often effective on submission. Colorado does not gate the dissolution behind a Secretary of State tax-clearance certificate, which keeps the state step straightforward.

The online filing fee is low, but because the Secretary of State sets and can revise it, confirm the current amount on the system before filing rather than relying on an out-of-date figure.

IRS Form 966

Form 966, “Corporate Dissolution or Liquidation,” is the federal filing unique to corporations. You file it with the IRS within 30 days after the resolution or plan to dissolve is adopted. An LLC taxed in the default way does not file it; a corporation, and an LLC that elected corporate taxation, does. Because the clock runs from the approval of the dissolution rather than from your Colorado filing, it is one of the most commonly missed steps, and it is covered on the final tax return page.

Final returns and Colorado state tax

A dissolving corporation files a final federal income tax return with the “final return” box checked, Form 1120 for a C-corp, Form 1120-S for an S-corp, plus final Colorado returns and, if it had employees, final employment tax returns. Separately, close any Colorado Department of Revenue accountssales tax, wage withholding, so those accounts do not keep expecting filings after the corporation is gone. Colorado does not require a separate clearance certificate to dissolve, but leaving Revenue accounts open is still a loose end worth tidying.

Closing the IRS account and the EIN

The step almost everyone misses: the IRS does not cancel an EIN. The number is permanent and never reassigned. You ask the IRS to close the business account attached to the EIN with a short letter, the corporation's exact legal name, EIN, address, and reason, after final returns are filed, and the IRS will not close it while returns are outstanding. Filing articles of dissolution with the Colorado Secretary of State does not do this.

One rule sits underneath the whole wind-up: creditors before shareholders. Winding up means notifying known creditors, settling or setting aside funds for the corporation's debts from its assets, and only then distributing anything left to shareholders. Paying shareholders while debts remain can expose them to clawback and undermine the liability protection the corporate form was meant to provide. If the corporation is insolvent or facing contested claims, that is the point to bring in an attorney rather than a filing service, the safe sequence is covered on dissolving an entity with debts.

Cost and timeline

Two numbers: the Colorado online filing fee, low, confirmed on the system before filing, and, if you want it handled, our service fee. Our pricing is $99 for a corporation that never really traded and $399 for one that operated and needs its IRS and Department of Revenue accounts closed, with the state fee at cost. A Colorado corporation that operated and had an EIN is a Complete Closure case.

On timing, Colorado's online system makes the state step one of the quicker ones, often effective on submission, while Form 966 and the IRS account closure run on the federal clock, generally several weeks each. We prepare and submit within 3 business days and quote the realistic window. See how long dissolution takes.

Rather have your Colorado corporation closed properly?

Closing a corporation the right way means the board and shareholder approvals are recorded, the articles of dissolution are filed, Form 966 lands inside its 30-day window, the final returns are marked final, and both the Department of Revenue and IRS accounts are closed, nothing left open. That is the whole job here. If you are not sure whether your corporation needs Complete Closure or something lighter, a specialist is on WhatsApp 24/7 and will tell you straight.
