Foreign Holding Company: CFC Rules, GILTI, and Form 5471

If you own more than 50% of the vote or value of a foreign holding company together with other US shareholders, the US tax rules on a foreign holding company treat it as a controlled foreign corporation (CFC) and tax most of its income to you currently, whether or not it ever sends cash to the United States.¹ On top of the tax, you owe a stack of annual information returns, and the penalties for missing them start at $10,000 per form, per year.²

When Your Foreign Company Becomes a CFC

A foreign corporation is a CFC if US shareholders collectively own more than 50% of the total combined voting power or total value of its stock. A “US shareholder” for this purpose is any US person who owns at least 10% of the vote or value, counting both direct holdings and shares attributed through related parties.¹

Entity classification matters at the same stage. A foreign corporation is a corporation. A foreign LLC that doesn’t affirmatively elect corporate treatment under the check-the-box regulations defaults to a disregarded entity if it has one owner, or a partnership if it has more than one.³ The default classification produces very different US results than corporate treatment, so the election is one of the first decisions to lock down.

What Gets Taxed Currently: Subpart F

Once a foreign holding company is a CFC, Subpart F requires US shareholders to include certain categories of its income on their own returns in the year earned, even with no distribution. The IRS treats shareholders as if they had received the income directly.⁴

Two buckets do most of the work:

Foreign personal holding company income — passive streams such as dividends, interest, rents, and royalties earned by the CFC.
Foreign base company income from related-party transactions — sales or services income where the CFC sits between affiliates without adding substantial economic value in its home country.

The reasoning is that income easily shifted between countries, or with no real connection to the CFC’s jurisdiction, shouldn’t sit offshore untaxed. Park royalty income in a Cayman holding company and Subpart F pulls it back onto your US return in the year it accrues.⁵

GILTI: The Broader Net on Active Income

The Global Intangible Low-Taxed Income regime catches what Subpart F doesn’t. Where Subpart F targets passive and related-party flows, GILTI sweeps in the CFC’s active earnings above a deemed routine return on tangible assets. The theory is that outsized profits relative to physical plant and equipment are driven by intangibles — brands, patents, know-how — that could have stayed in the US.⁶

The math: start with net tested income (active income not already caught by Subpart F), subtract a deemed tangible income return equal to 10% of qualified business asset investment (the average adjusted basis of depreciable tangible property used in the business), and whatever remains is GILTI, taxable to the US shareholder immediately.⁶

Corporate vs. Individual Rates in 2026

For tax years beginning in 2026, US corporate shareholders can claim a 40% deduction on their GILTI inclusion under Section 250. Applied against the 21% corporate rate, that produces an effective federal rate of 12.6% on GILTI.⁷ That is up from the 10.5% effective rate through 2025, when the deduction was 50%.

Individual US shareholders don’t automatically qualify for the Section 250 deduction. Without planning, GILTI hits them at ordinary rates up to 37%.

High-Tax Exclusion

CFC income already taxed at a high enough rate abroad can be excluded from GILTI. The threshold is an effective foreign tax rate above 18.9%, which equals 90% of the 21% US corporate rate. If the CFC’s income in a tested unit was taxed at or above that rate, the US shareholder can elect to exclude it. The election matters most for holding companies with subsidiaries in countries whose corporate rates sit near or above 19%.

The Section 962 Election for Individual Owners

Individual US shareholders of a CFC have one planning tool the GILTI math makes essential. By making a Section 962 election, the individual is treated as a domestic corporation for purposes of computing tax on CFC inclusions, both Subpart F and GILTI. That unlocks the Section 250 deduction and the 21% corporate rate, dropping the effective GILTI rate from as high as 37% down to 12.6%.⁸

The election also opens the door to deemed-paid foreign tax credits against the CFC income, which can reduce or eliminate remaining US tax. The trade-off: when the CFC later distributes those earnings as an actual dividend, the individual must recognize the distribution as income to the extent it exceeds amounts already taxed under the inclusion. Tracking previously taxed earnings becomes its own compliance task. The election is made annually on the income tax return, so it can be adopted or dropped year to year.

If You’re Below the CFC Threshold: PFIC

When US ownership doesn’t reach the CFC threshold, the Passive Foreign Investment Company rules often apply instead, and they’re harsher. A foreign corporation is a PFIC if 75% or more of its gross income is passive, or at least 50% of its assets produce or are held to produce passive income.⁹ A holding company whose main activity is owning subsidiary stock and collecting dividends will almost always meet one of these tests.

The default PFIC regime is punitive by design. An “excess distribution” from a PFIC, or a gain on sale of PFIC stock, is allocated ratably across every year of your holding period, taxed at the highest ordinary rate for each year, with an interest charge added on top. The point is to make deferral worthless by recapturing the time value of the delayed tax.

Two elections avoid the default regime:

Qualified Electing Fund (QEF) — you include your share of the PFIC’s ordinary earnings and net capital gains each year, similar to CFC inclusions. The PFIC has to provide you with annual income statements, which not every foreign fund will do.
Mark-to-market — if the PFIC stock is marketable, you recognize annual gain or loss based on changes in fair market value, turning unrealized appreciation into current income.

With no election in place, the default excess distribution rules apply automatically. Fixing years of missed PFIC reporting after the fact is one of the uglier problems in international tax compliance.

Foreign Tax Credits and the GILTI Basket

Foreign tax credits are the main defense against double taxation on CFC income. When a CFC pays corporate tax in its home country, the US shareholder can generally credit those foreign taxes against US tax on the same income. The credit is capped at the US tax that would apply to foreign-source income in each separate category.¹⁰

GILTI sits in its own separate basket. Foreign taxes paid on GILTI can only offset US tax on GILTI, not on other categories such as general or passive income. And excess credits in the GILTI basket cannot be carried back or carried forward.¹⁰ If a CFC pays more foreign tax in a year than the US tax on its GILTI, the excess is lost. Use it or lose it.

For corporate shareholders, the Section 250 deduction also reduces the foreign tax credit limitation. Because the deduction shrinks the taxable GILTI amount, it also shrinks the maximum credit available, which can create situations where a CFC’s foreign rate is low enough to generate GILTI but high enough that credits get partially wasted.

Transfer Pricing on Intercompany Transactions

Every transaction between you and your foreign holding company — loans, service fees, royalty payments, asset transfers — must be priced at arm’s length. Under IRC Section 482, the IRS can reallocate income between related parties if their pricing doesn’t match what unrelated parties would agree to in comparable circumstances.¹¹ The agency focuses heavily on arrangements where valuable intellectual property is transferred to a low-tax holding company that then licenses it back to operating subsidiaries. If the royalty rates or cost-sharing payments don’t hold up, the IRS will reassign the income to the US and can impose accuracy-related penalties on top.¹² Contemporaneous documentation, prepared at the time of the transaction rather than after an audit begins, is the practical defense.

The Forms You Have to File

The reporting load is heavy, and the penalties often dwarf the underlying tax. For several of these forms, a missed filing also keeps the statute of limitations on the related income tax return open indefinitely.

Form 5471: Information Return for Foreign Corporations

US persons who are officers, directors, or shareholders in a CFC file Form 5471 with their income tax return, including the CFC’s full financial statements and a breakdown of US shareholders and the ownership chain.¹³ The penalty for each failure to file a complete and accurate Form 5471 is $10,000. If the IRS sends a notice and the form still isn’t filed within 90 days, an additional $10,000 accrues for each 30-day period of continued noncompliance, up to a $50,000 continuation penalty.²

Forms 8992 and 8993: GILTI and Section 250

Form 8992 computes the GILTI inclusion, with pro rata shares of each CFC’s tested income and qualified business asset investment.¹⁴ Corporate shareholders, and individuals who have made a Section 962 election, then file Form 8993 to calculate the Section 250 deduction.⁸ Both forms attach to the income tax return, and errors flow straight into the tax liability.

Form 926: Transfers of Property to Foreign Corporations

Form 926 reports transfers of property — cash, real estate, intellectual property, stock — by a US person to a foreign corporation.¹⁵ It covers the initial capitalization of your foreign holding company and later contributions. The penalty for failing to file is 10% of the fair market value of the transferred property, capped at $100,000 per transfer unless the failure was intentional, in which case the cap is removed.¹⁶

FBAR: Foreign Bank Account Reporting

Any US person with a financial interest in or signature authority over foreign financial accounts must file FinCEN Form 114 (the FBAR) if the combined value of those accounts exceeds $10,000 at any point during the year.¹⁷ The FBAR is filed with FinCEN, not the IRS, and is due April 15 with an automatic extension to October 15. Non-willful penalties can reach $10,000 per account per year (inflation-adjusted). Willful violations carry a penalty up to 50% of the highest account balance during the year, or $100,000 (inflation-adjusted), whichever is greater.¹⁸

Form 8938: FATCA Reporting

Separate from the FBAR, Form 8938 reports specified foreign financial assets with the income tax return. It covers a broader range of assets than the FBAR, including foreign stock and securities not held in a financial account, foreign partnership interests, and foreign hedge fund interests, but has higher filing thresholds.¹⁸ For taxpayers living in the United States, the threshold is $50,000 in total value on the last day of the tax year or $75,000 at any time during the year (doubled for joint filers). For those living abroad, the thresholds jump to $200,000 on the last day or $300,000 at any time ($400,000/$600,000 for joint filers).¹⁹

The penalty for failing to file Form 8938 is $10,000, with an additional $10,000 for each 30-day period of continued noncompliance after an IRS notice, up to a $50,000 maximum.²⁰ Ownership of a foreign holding company will almost always trigger Form 8938 in addition to the FBAR, because the interest in the foreign corporation is itself a specified foreign financial asset.

Beneficial Ownership Information

Under the Corporate Transparency Act, foreign entities registered to do business in any US state must file beneficial ownership information (BOI) reports with FinCEN. As of 2025, FinCEN narrowed the requirement so that domestic companies and US persons are exempt; only foreign reporting companies remain subject.²¹ A foreign holding company registered with a secretary of state to conduct business in the United States must file within 30 calendar days of receiving notice that its registration is effective. Penalties include daily civil fines exceeding $500 per day. A foreign holding company with no US state registration generally falls outside the BOI obligation.

Where You Incorporate Still Matters

Jurisdiction choice is not just a rate comparison. Tax treaties between the holding company’s country and the countries where its subsidiaries operate determine withholding on dividends, interest, and royalties flowing through the structure, and a US treaty with the holding company’s jurisdiction can reduce US withholding on outbound payments and open mutual agreement procedures for resolving double-taxation disputes. A participation exemption in the holding company’s jurisdiction can eliminate local tax on dividends from subsidiaries and on gains from selling subsidiary shares, making the holding company a tax-neutral conduit for consolidating profits before they move upward.

Economic substance has become the single biggest operational concern. Incorporating in a low-tax jurisdiction without genuine local management, employees, or decision-making invites both US and foreign authorities to disregard the entity. If the IRS determines that the true place of management and control is the United States, all of the holding company’s income becomes subject to full US corporate tax. Real office space, local directors who make real decisions, and enough staff to justify the entity’s existence are the baseline. A brass-plate office with a mail-forwarding service will not hold up.
