Form 966: Understanding Corporate Dissolution or Liquidation

Download Form 966

The life cycle of a business is dynamic and often subject to change. Sometimes, companies may need to dissolve or liquidate due to various reasons, such as financial difficulties, strategic restructuring, or the end of the business's life cycle. When a corporation decides to dissolve or liquidate, it is required to file a Form 966 with the Internal Revenue Service (IRS) in the United States.

Form 966, officially known as "Corporate Dissolution or Liquidation," is a document filed with the IRS to notify them about a corporation's decision to dissolve or liquidate. The IRS requires this form to be filed within 30 days of the corporation adopting a resolution or plan to dissolve or liquidate its affairs.

In this blog post, we will explore Form 966, its purpose, and the key information required to complete it accurately.

Purpose of Form 966

Form 966 serves several purposes, both for the IRS and the corporation:

IRS notification: By filing Form 966, the corporation notifies the IRS of its intention to dissolve or liquidate. This enables the IRS to update its records and ensure compliance with tax regulations.

**Tax clearance: **Filing Form 966 helps the corporation obtain tax clearance from the IRS. This means that the corporation has fulfilled its tax obligations before dissolving or liquidating, reducing the risk of future tax liabilities.

Final tax returns: Form 966 prompts the IRS to process the corporation's final tax returns, including the final income tax return and, if applicable, the final employment tax return (Form 941).

Benefits of Form 966

While there are certain requirements and obligations associated with filing Form 966, there are several benefits that corporations can derive from completing this form. Some of the benefits of Form 966 include:

Finalizing the winding down process: Filing Form 966 is an essential step in formally closing down a corporation. By submitting this form, the corporation notifies the IRS about its intention to dissolve or liquidate, allowing for the finalization of the winding down process.

Termination of tax obligations: When a corporation files Form 966, it serves as a notification to the IRS that the company will no longer conduct business. This helps to terminate various tax obligations, including the need to file future tax returns and pay corporate taxes.

**Stopping the accrual of penalties and interest: **By filing Form 966 and initiating the dissolution or liquidation process, a corporation can halt the accrual of penalties and interest on any outstanding tax liabilities. This can provide financial relief and prevent additional costs from accumulating.

Establishing a final tax year: Form 966 helps establish the final tax year for the corporation. Once the form is filed, the corporation's tax year is deemed to have closed, simplifying the tax reporting process and ensuring clarity regarding tax obligations for both the corporation and its shareholders.

Providing legal protection: Filing Form 966 helps protect the corporation and its officers from potential legal issues that may arise after dissolution or liquidation. It provides evidence that the corporation has followed the proper procedures and complied with IRS requirements, which can be important in case of any future disputes or claims.

Who Is Eligible To File Form 966?

Form 966 is typically filed by C corporations (including S corporations that were previously C corporations) that have made the decision to terminate their existence and wind up their affairs.

Here are some key points regarding eligibility to file Form 966:

C corporations: The primary category of corporations eligible to file Form 966 is C corporations. C corporations are the standard type of corporations, and they must file Form 966 if they choose to dissolve or liquidate.

S corporations: S corporations that were previously C corporations and have converted to S corporation status can also use Form 966 to report their dissolution or liquidation. If an S corporation has always been an S corporation and has not been a C corporation at any point, it does not need to file Form 966.

Limited liability companies (LLCs): By default, LLCs are not required to file Form 966 when they dissolve or liquidate. However, if an LLC elected to be taxed as a C corporation at any time, it would need to file Form 966 if it decides to dissolve or liquidate.

Foreign corporations: Foreign corporations, which are corporations formed outside of the United States, are not eligible to file Form 966.
