Form 5471

Form 5471, Information Return of U.S. Persons With Respect To Certain Foreign Corporations, is an information return. It computes no tax. It is the disclosure vehicle that supports Subpart F income, Section 956 inclusions, the global intangible low-taxed income regime (now net CFC tested income), previously taxed earnings and profits tracking, and the deemed paid foreign tax credit under Section 960.

Three consequences follow, and all three are where firms lose money. It is due whether or not there is income, tax, or activity, so a dormant foreign corporation still files and a loss year still files. A substantially incomplete form is treated as no form at all, so filing with required schedules left blank neither starts the clock nor satisfies Section 6038. And it is filed per foreign corporation, per filer, per annual accounting period, so five CFCs in a structure means five forms and a top-tier filing does not cover lower-tier entities. It attaches to the filer's income tax return and is due with that return, extensions included. There is no separate filing address and no separate extension.

Five categories drive who files. Category 1 covers US shareholders of a specified foreign corporation. Category 2 covers US officers and directors on a qualifying acquisition, and it is the one most often missed, because the filer is an individual with no equity. Category 3 is event-driven, triggered by acquisitions, dispositions, and status changes, which means it never appears in a rollforward. Category 4 covers control for an uninterrupted period of 30 days or more, carries the heaviest schedule load, and is the only category that files Schedule M. Category 5 covers US shareholders of a CFC who held the stock on the last day of the year in which it was a CFC. Categories overlap, and a filer checks every applicable box and files the union of the required schedules. Filing only for the "highest" category is a common and expensive shortcut.

Every category test turns on ownership measured directly, indirectly, and constructively, under Section 318 as modified by Section 958(b). Attribution creates filers who own nothing economically, so an ownership workpaper that starts from the cap table rather than from an attribution analysis will miss them.

The penalty regime is what makes process failures expensive. Section 6038 imposes $10,000 per form per year before anyone examines whether the numbers were right, with continuation penalties, and Section 6501(c)(8) holds the statute of limitations open on the taxpayer's entire return until the information is furnished.

For tax years of foreign corporations beginning after December 31, 2025, scoping changes. Section 958(b)(4) is restored, repealing the downward attribution rule that created accidental CFCs, and new Section 951B introduces a parallel regime for foreign-controlled arrangements. Some entities stop being CFCs and some filers stop being US shareholders, so the filer list has to be rebuilt rather than rolled forward.

What goes wrong on a 5471 is almost never a tax opinion. It is a missing input: an unchecked category box, a skipped Schedule M, a reference ID that moved between years, a Schedule J rolled forward from a workbook nobody has reconciled.
