U.S. taxpayers holding any ownership stake in a foreign corporation—whether direct or indirect—must navigate a formidable range of federal filing and tax obligations. Chief among these requirements is Form 5471 (Information Return of U.S. Persons With Respect to Certain Foreign Corporations), but depending on the structure of your foreign entity, you or the corporation itself may also need to file additional forms such as Form 1120-F, Form 8833, or others. Failing to comply—whether intentionally or inadvertently—can lead to formidable civil penalties, possible criminal tax exposure, and the kind of life-altering consequences that the IRS vigorously pursues to maintain tax compliance. Below is a comprehensive overview of what you need to know if you have an interest in a foreign corporation.

Who Must File Form 5471

Form 5471 is central to U.S. international tax enforcement. Multiple categories of filers trigger the requirement, including:

1. U.S. Shareholders of a Controlled Foreign Corporation (CFC). A foreign corporation is generally considered “controlled” if one or more U.S. shareholders own more than 50% of its vote or value. A U.S. shareholder, for Form 5471 purposes, typically holds at least 10% of the total voting power or value of the foreign corporation’s shares.
2. Officers or Directors of Foreign Corporations experiencing a 10% (or greater) ownership change by a U.S. person.
3. Shareholders Whose Ownership Rises Above or Falls Below 10%. Trigger events like crossing the 10% threshold or disposing enough stock to move below 10% can each mandate a filing.
4. U.S. Persons in “Control.” Having more than 50% of the voting power or total share value places you in control for Form 5471 filing purposes.
5. Long-Term (10%+) Owners. If you own at least 10% of a CFC for an uninterrupted 30-day period and still hold it on the last day of the tax year, you likely must file.

A common scenario involves GILTI (Global Intangible Low-Taxed Income): U.S. shareholders holding at least 10% of a CFC may have to include their share of GILTI in current income, which often requires additional schedules and disclosures on Form 5471.

Due Dates and Penalties

Form 5471 is generally due with your annual tax return—April 15 (or October 15 under extension) for individuals and March 15 (or September 15 under extension) for corporations. Penalties begin at $10,000 per year per entity for each required Form 5471 that is missing or materially incomplete, and they escalate for continued non-compliance.

Various foreign information reporting forms are required to disclose offshore corporations, LLCs, partnerships, and other business and foreign financial accounts. Filing them correctly is an extremely complex process—you should never simply submit without proper review, as the potential penalties can be devastating.

When a Foreign Corporation Must File Form 1120-F

A foreign corporation that is considered to be engaged in a U.S. trade or business faces its own filing requirements under Form 1120-F (U.S. Income Tax Return of a Foreign Corporation). Under Reg. § 1.6012-2(g)(1):

• A foreign corporation must file Form 1120-F even if it has no effectively connected income (ECI) or no U.S.-source income and even if all its income is entirely exempt under the Internal Revenue Code (IRC) or by treaty.
• If the corporation genuinely has no U.S.-taxable income, it may file a “protective return,” providing only identifying details and a clear statement explaining the nature and amount of each claimed exclusion. Form 8833 must generally accompany the protective return if a treaty-based position is asserted, consistent with Reg. § 301.6114-1(a)(1)(ii).

Claims of “No Permanent Establishment”

Be cautious if a foreign corporation asserts it has no U.S. permanent establishment under a treaty and thus does not need to file. While it may reduce or eliminate tax liability, § 6114 requires disclosure if you rely on a treaty-based return position. Failing to file the appropriate forms can trigger separate penalties of $10,000 per omitted reportable event.

Foreign Corporations Subject to Tax Under Subtitle A

Even if the foreign corporation is not engaged in a U.S. trade or business, Regs. § 1.6012-2(g)(1)(i) and 1.6012-2(g)(2)(i)(a) can still require a return to report certain U.S.-source income. This includes FDAP income taxable under § 881 (e.g., dividends, royalties) or certain effectively connected income under § 882(d) or (e) unless the liability is fully satisfied through withholding at the source. Even then, a filing obligation might persist if the corporation seeks a refund or is subject to the accumulated earnings tax.

Due Dates

As a default, a foreign corporation must file by the 15th day of the third month after the tax year ends (March 15 for a calendar-year filer). If it has no U.S. office or fixed place of business, it automatically receives a three-month extension, but interest still accrues on any tax not paid by the original due date. All foreign corporations can file Form 7004 to extend the deadline up to six months total, albeit interest and penalties may apply if taxes are unpaid by the original due date.

Information Returns Required of Foreign Corporations

Foreign corporations may be subject to additional U.S. information reporting, including:

• Forms 1096 and 1099 for certain payments to U.S. recipients.
• Form 1042 if it pays U.S.-source income to non-U.S. persons.
• Form 5472 for related-party transactions if the corporation is considered engaged in a U.S. trade or business.

Effectively Connected Income (ECI), Branch Profits Tax, and Related Considerations

When a foreign corporation conducts a U.S. trade or business, its Effectively Connected Income (ECI) is taxed at the standard corporate rates under § 882, with deductions allowed for expenses incurred to generate that income. In addition, foreign corporations may be subject to a branch profits tax, which is imposed on the repatriated profits from a U.S. branch, effectively treating such distributions similarly to dividends from a domestic subsidiary. On the other hand, FDAP income—such as dividends or royalties that are not treated as ECI—is typically subject to a 30% gross-basis tax under § 881 unless a tax treaty provides for a lower rate or an exemption.

Anti-Deferral Provisions Affecting U.S. Owners

The IRS’s reach also extends to U.S. shareholders of foreign corporations through anti-deferral provisions such as the Subpart F rules, Passive Foreign Investment Company (PFIC) regulations, and restrictions under § 367 on tax-free transfers of property to foreign entities. Even if the foreign corporation itself avoids direct U.S. taxation, U.S. owners can still be taxed on any undistributed foreign profits or face other adverse consequences intended to deter offshore tax evasion.

Tax Treaties and § 6114 Disclosures

Tax treaties further complicate the landscape by potentially modifying or reducing a foreign corporation’s U.S. tax liability. Often, these treaties require that a foreign corporation have a “permanent establishment” in the United States before U.S. tax is imposed on its business profits, and they may also lower the 30% withholding rate on U.S.-source income. However, if you or the foreign corporation rely on a treaty-based return position, § 6114 mandates that this position be disclosed, with failure to do so triggering per-event penalties under § 6712 that can accumulate significantly with multiple transactions or payments.

Classification of Foreign Entities Under Check-the-Box Regulations

Finally, the proper classification of a foreign entity under the check-the-box regulations is critical. A foreign entity with multiple owners is typically classified as a corporation if all owners have limited liability. Conversely, if any owner is subject to personal liability for the entity’s debts, the entity may be classified as a partnership or a disregarded entity. Incorrect classification can lead to missed filings—such as erroneously filing a Form 5471 when a partnership return was required—and may result in unforeseen tax liabilities.

Contact the Tax Law Offices of David W. Klasing if You Have an Interest in a Foreign Corporation

If you have failed to file required foreign information returns (Forms 5471, 1120-F, 8865, FBAR, etc.) or neglected to report offshore income, you may avert crippling penalties and potential criminal tax exposure by making a voluntary disclosure before the IRS starts a high-risk audit or far worse, criminal tax investigation. This can be achieved through a domestic or offshore voluntary disclosure or other streamlined programs, depending on whether your conduct is deemed willful or non-willful. Although you must generally pay back taxes, interest, and specific penalties, you often gain a near-guaranteed pass on criminal tax prosecution if you disclose first.

Remember: Only an experienced Criminal Tax Defense Attorney—not a non-attorney preparer—can guide you through a voluntary disclosure without engaging in the unauthorized practice of law. Attorney-client privilege and work-product protections are also critical to shielding you from self-incrimination, particularly if you have unfiled tax returns or suspect your actions might be viewed as willful tax fraud.
