The anti-inversion rules in IRC Section 7874 shut down the tax benefits of moving a U.S. corporation under a foreign parent. If former U.S. shareholders end up owning at least 80% of the new foreign parent, the foreign corporation is treated as a domestic corporation for every purpose of the tax code. If they own at least 60% but less than 80%, the foreign parent keeps its foreign status, but the U.S. subsidiary loses the ability to shelter “inversion gain” with net operating losses or foreign tax credits for ten years. Both tiers apply only when the foreign group lacks substantial business activities in its country of organization.
When Section 7874 Applies
Three conditions must all be present for a foreign corporation to become a “surrogate foreign corporation” under the statute.1Office of the Law Revision Counsel. 26 USC 7874 – Rules Relating to Expatriated Entities and Their Foreign Parents
The foreign corporation must directly or indirectly acquire substantially all of the properties of a domestic corporation, or substantially all of the properties making up a domestic partnership’s trade or business. Acquiring the stock of the domestic corporation counts, because the Treasury Regulations treat a stock acquisition as an indirect acquisition of the underlying assets.2Legal Information Institute. 26 CFR 1.7874-2 – Surrogate Foreign Corporation
After the acquisition, former shareholders of the domestic corporation must hold at least 60% of the foreign parent’s stock by vote or value, and they must hold it “by reason of” having held stock in the domestic corporation.3Legal Information Institute. 26 USC 7874(a)(2)(B) – Surrogate Foreign Corporation The IRS looks at whether shareholders received the foreign parent’s stock as consideration for their domestic stock, not whether the same people happen to own shares in both entities.
Finally, the expanded affiliated group that includes the foreign parent must not have substantial business activities in the foreign country where the parent is organized. If all three conditions line up, the domestic entity becomes an “expatriated entity” and the penalty provisions turn on.
The 80 Percent Threshold: Foreign Status Ignored Entirely
When former domestic shareholders hold at least 80% of the new foreign parent’s stock by vote or value, Section 7874(b) treats the foreign corporation as a domestic corporation for all purposes of the Internal Revenue Code.1Office of the Law Revision Counsel. 26 USC 7874 – Rules Relating to Expatriated Entities and Their Foreign Parents The entity files U.S. returns and pays the 21% corporate income tax on its worldwide profits. Its foreign incorporation becomes a legal fiction for tax purposes.
Because the entity is domestic, there is no foreign status left to exploit. Dividends it pays are sourced domestically, withholding follows domestic rules, and the same international reporting regime applies as for any U.S.-incorporated company. Section 7874(f) blocks any escape through a tax treaty: no treaty obligation can be construed as providing an exemption from these provisions. The practical result is that an 80% inversion produces no tax advantage at all, and can be worse than doing nothing because the restructuring itself can generate taxable events.
The 60 Percent Threshold: Ten Years of Restricted Tax Attributes
When former domestic shareholders own at least 60% but less than 80%, the foreign parent keeps its foreign status. The U.S. subsidiary, however, cannot report taxable income for any year in the “applicable period” that is less than its inversion gain for that year.1Office of the Law Revision Counsel. 26 USC 7874 – Rules Relating to Expatriated Entities and Their Foreign Parents
Inversion gain under Section 7874(d)(2) captures two things: income or gain recognized from transferring stock or other property during the applicable period as part of the inversion, and any income received from licensing property to a foreign related person after the acquisition. The licensing category is where the real teeth are. Companies that move patents, trademarks, or proprietary technology to the foreign parent and collect royalties find that income fully captured.
The applicable period runs for ten years, beginning on the first date properties are acquired as part of the inversion and ending ten years after the last such acquisition date. During that decade, the domestic entity cannot use net operating losses or foreign tax credits to reduce its liability below the inversion-gain floor. Legitimately accumulated losses and credits still exist on paper. They just cannot be applied to the income the inversion was designed to generate.
Loss of Qualified Dividend Treatment
The 60% threshold also reaches individual shareholders. Under Section 1(h)(11)(C)(iii), dividends from a corporation that becomes a surrogate foreign corporation after the enactment date do not qualify as “qualified dividend income.”4Legal Information Institute. 26 USC 1(h)(11) – Definition: Qualified Dividend Income Qualified dividends are taxed at the preferential capital gains rate of up to 20%; ordinary dividends run at the shareholder’s regular rate, up to 37%. This exclusion doesn’t apply at the 80% level, because there the entity is domestic for all tax purposes and its dividends are ordinary domestic dividends.
How the Ownership Percentage Is Measured
The 60% and 80% tests turn on a fraction: former domestic shareholders’ stock in the foreign parent (received by reason of their prior domestic ownership) over the foreign parent’s total outstanding stock. Several categories of stock get pulled out of that fraction to prevent manipulation.
Stock held by members of the foreign parent’s expanded affiliated group is excluded from both numerator and denominator.5eCFR. 26 CFR 1.7874-1 – Disregard of Affiliate-Owned Stock Stock sold in a public offering as part of the acquisition is also excluded, and so is “hook stock,” where a subsidiary holds shares of its own parent. Separately, “disqualified stock” targets shares issued in exchange for cash, marketable securities, or certain related-party obligations rather than operating assets; issuing stock for cash inflates the denominator and pushes the ownership percentage down, so those shares are disregarded.
Anti-Stuffing Rules
Companies have tried to duck the 80% threshold by “stuffing” the foreign acquirer with extra assets right before closing, making the foreign entity look larger. Treasury addressed this: any assets acquired with a principal purpose of avoiding the 80% rule are disregarded, whether passive or active.6U.S. Department of the Treasury. Fact Sheet: Additional Treasury Actions to Rein in Corporate Tax Inversions Section 7874(c)(4) reaches further, directing the IRS to disregard any transfer of properties or liabilities that is part of a plan with a principal purpose of avoiding the statute.7Office of the Law Revision Counsel. 26 USC 7874 – Rules Relating to Expatriated Entities and Their Foreign Parents
Third Country Structures
Some deals route through an intermediary jurisdiction: a U.S. company merges with a UK target, but the new parent incorporates in Ireland. Under 26 CFR 1.7874-9, when the foreign acquirer completes a “covered foreign acquisition” and ends up as a tax resident of a country different from that of the acquired foreign corporation, stock held by reason of owning shares in the acquired foreign entity is excluded from the denominator.8eCFR. 26 CFR 1.7874-9 – Disregard of Certain Stock in Third-Country Transactions Pulling that stock out of the denominator raises the former U.S. shareholders’ percentage. A deal that would have come in at 55% can jump above 60% or 80% once the third-country stock is stripped. The rule applies to domestic entity acquisitions completed on or after July 12, 2018.
The Substantial Business Activities Exception
A foreign acquirer avoids surrogate status entirely if the expanded affiliated group has substantial business activities in the country of organization. The Treasury Regulations set a quantitative safe harbor built on a 25% test with three prongs, all of which must be satisfied at the same time:9Federal Register. Substantial Business Activities
- At least 25% of the group’s employees, measured by both headcount and total compensation, must be based in the foreign country.
- At least 25% of the group’s total asset value must be physically located there.
- At least 25% of the group’s total gross income must be derived there during the testing period.
Failing even one prong knocks the group out of the safe harbor. The regulations use a look-back testing period so that companies cannot temporarily inflate foreign operations just before closing. This exception exists because not every cross-border deal is tax-motivated: when a U.S. company combines with a foreign company that has real employees, plants, and revenue at home, the inversion rules were not meant to apply.
Excise Tax on Corporate Insiders
Section 7874 is not the only cost. Section 4985 imposes a separate 20% excise tax on stock-based compensation held by corporate insiders during an inversion.10Office of the Law Revision Counsel. 26 USC 4985 – Stock Compensation of Insiders in Expatriated Corporations It applies to any “disqualified individual,” meaning anyone subject to the insider reporting requirements of Section 16(a) of the Securities Exchange Act — officers, directors, and 10% shareholders. The tax runs at the 20% rate specified in Section 1(h)(1)(D), applied to the value of all specified stock compensation (options, stock appreciation rights, restricted stock, and other awards tied to the expatriated corporation’s shares) held by the individual or a family member during the 12-month period starting six months before the expatriation date. The people who approved the inversion pay personally, on top of the corporate-level penalties.
Shareholder-Level Gain Under Section 367(a)
When U.S. shareholders exchange their domestic stock for shares in the new foreign parent, Section 367(a) generally requires them to recognize gain. It works by stripping the foreign corporation of its “corporation” status for the tax-free reorganization rules, so what would have been a tax-free swap under Section 354 or 351 becomes taxable.11Internal Revenue Service. IRM 4.61.11 – Development of IRC 367 Transactions and Issues Shareholders with appreciated stock face immediate capital gains on the difference between the fair market value of the foreign shares received and their basis in the domestic shares surrendered. Treasury Regulation 1.367(a)-3(c) offers narrow exceptions that can defer the gain, but they come with gain recognition agreements that can span years and be triggered by later restructuring.
Reporting Obligations
A U.S. person who transfers property to a foreign corporation in an exchange covered by Sections 332, 351, 354, 355, 356, or 361 must report the transfer under Section 6038B.12Office of the Law Revision Counsel. 26 USC 6038B – Notice of Certain Transfers to Foreign Persons The penalty for failing to file is 10% of the fair market value of the transferred property, capped at $100,000 unless the failure was due to intentional disregard, in which case there is no cap.13Internal Revenue Service. Form 926 Filing Requirement for U.S. Transferors of Property to a Foreign Corporation A separate 40% penalty applies to any underpayment attributable to an undisclosed foreign financial asset understatement. Reasonable cause can excuse the penalty, but the bar is high in a multibillion-dollar transaction.
The domestic corporation also files Form 8806 to report the change in control when the fair market value of the acquired stock is $100 million or more and shareholders must recognize gain under Section 367(a).14eCFR. 26 CFR 1.6043-4 – Information Returns Relating to Certain Acquisitions of Control and Changes in Capital Structure Missing the reporting also extends the assessment period: under Section 6501(c)(8), the IRS gets three additional years from the date the required information is finally furnished.
