What is Form 851?

Form 851, the Affiliations Schedule, is an essential document for corporations to disclose their relationships with other companies. It identifies the primary parent corporation and outlines all its connected subsidiaries. This form plays a vital role in ensuring that each subsidiary is included in the same group and provides details on tax credits and payments for each corporation. The Internal Revenue Service (IRS) relies on this information to accurately assess and collect taxes from affiliated groups and verify that each subsidiary meets the ownership requirements needed to be part of the group.

What is Form 851 used for?

Form 851 is important for corporations that are part of a group. It helps clarify relationships and financial details among members. Here’s what it’s used for:

Once completed, the IRS uses Form 851 to verify compliance with tax laws and accurately assess tax liabilities for affiliated corporations, ensuring proper consolidation of income tax returns.

When is Form 851 not required?

You don't need to file Form 851 if your group filed a consolidated return for the previous taxable year. Also, if your group submitted Form 1122, Authorization and Consent of Subsidiary Corporation, for the current year, you can skip Form 851 altogether.

When is Form 851 due?

The deadline for Form 851 is the same as the consolidated tax return for the affiliated group. For corporations on a calendar year, this is usually the 15th day of the 4th month after the tax year ends. For those with fiscal years ending June 30, it is the 15th day of the 3rd month after the tax year ends.
