New Tax Provision Creates Compliance Maze for Foreign-Owned U.S. Firms

A U.S. tax code provision is creating significant uncertainty and new compliance burdens for American businesses with foreign ownership, particularly those structured as domestic partnerships. The rule, under Internal Revenue Code Section 6038A, has effectively created a new category of reporting entity—a “foreign-controlled foreign corporation”—forcing many companies to re-evaluate their tax filing obligations and potential exposure to steep penalties. The change centers on how the Internal Revenue Service (IRS) defines a “reporting corporation.” Previously, the focus was primarily on U.S. entities with substantial foreign ownership. However, recent regulations and their interpretation have broadened this scope. Now, if a foreign corporation is a partner in a U.S. partnership, the IRS may treat that foreign partner as being engaged in a U.S. trade or business. This classification can trigger a cascade of reporting requirements for other foreign entities related to that partner, even if they have no other direct connection to the United States. This reclassification is proving to be a complex issue for many international business structures. According to tax professionals, including Dean Peterson of the firm EisnerAmper who recently commented on the matter, companies need to begin assessing their exposure immediately. The core of the issue is that a foreign corporation that was not previously considered a controlled foreign corporation (CFC) might now be deemed one for the specific purpose of information reporting. This change primarily affects the requirement to file Form 5472, “Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business.” Form 5472 is used to disclose certain transactions between the U.S.-based reporting corporation and its foreign-related parties. The expansion of who is considered a reporting corporation means that a wider net of international transactions must now be reported to the IRS. For example, a transaction between a U.S. partnership's foreign partner and that partner's own foreign parent company might now be a reportable event, a scenario many businesses would not have previously considered within the scope of U.S. tax compliance. The financial stakes for non-compliance are substantial. The penalty for failing to file a required Form 5472 or for filing an incomplete form starts at $25,000 per form, per year. If the failure continues after notification from the IRS, additional penalties can accrue. For small and mid-sized businesses, which often operate with leaner compliance departments than their multinational counterparts, such penalties could be crippling. The ambiguity surrounding the new provision makes it a significant risk area, as companies may be unaware of their new obligations until they are audited. The complexity lies in tracing ownership and control through multi-layered international structures. A U.S. business might be part of a domestic partnership that has a foreign corporate partner, which in turn is owned by another foreign entity. Under the current interpretation of Section 6038A, the U.S. business may have a new responsibility to report transactions involving these foreign affiliates. This requires a level of visibility into the global corporate structure that many mid-sized U.S. operations may not possess, creating an urgent need for detailed organizational mapping and transactional analysis. This regulatory shift is part of a broader trend by the U.S. Treasury and the IRS to increase transparency and combat strategies that shift profits out of the United States. While the policy goal is aimed at large multinational enterprises, the practical application of the rule is catching many smaller and mid-sized foreign-owned businesses in its web. These companies often use partnership structures for legitimate investment and operational reasons, not for aggressive tax avoidance, but are now faced with the same complex reporting regime. In our experience, these expanded reporting rules create a classic compliance trap for the very international investors and mid-sized companies the U.S. seeks to attract. The language of the code is dense, and the definitions of control and related parties can be surprisingly broad, pulling in entities that have no obvious operational link to the U.S. business. We’ve seen clients surprised to learn that a transaction between two foreign sister companies is now potentially reportable to the IRS simply because of a shared investment in a U.S. partnership. Proactive analysis of the entire ownership chain is no longer optional; it's a fundamental risk management step to avoid six-figure penalties. This is precisely the kind of intricate cross-border issue where specialized guidance in tax preparation and compliance is essential.
