What Is a Corporate Inversion?
A Corporate Inversion is a cross-border tax restructuring under which a domestic parent company becomes a subsidiary of a foreign parent, as national law defines.
Also known as: Tax Inversion, Corporate Expatriation.
How Corporate Inversion works
A Corporate Inversion occurs when a foreign corporation acquires substantially all the properties of a domestic corporation, usually through a share exchange, so that the domestic group's shareholders end up owning a foreign parent, and the residence country's anti-inversion rules then decide whether the new structure is respected for tax purposes. In the United States, Internal Revenue Code section 7874 treats the foreign parent as a domestic corporation where former shareholders hold at least 80 percent of its stock by vote or value after an acquisition completed after March 4, 2003. At 60 percent or more but below 80 percent, the domestic company becomes an expatriated entity whose taxable income cannot fall below its inversion gain for an applicable period ending 10 years after the last acquisition. Neither result applies where the expanded affiliated group has substantial business activities in the foreign country, which Treasury regulations measure as at least 25 percent of group employees, compensation, assets and income located there, and other countries apply different rules or none specific to inversions.
Corporate Inversion vs Redomiciliation
Unlike Redomiciliation, which moves an existing company's legal seat to another jurisdiction while preserving the same entity, a Corporate Inversion places a foreign company above the domestic group as the new parent.
Example
Illustrative example: A founder relocating from the United States to Country B forms a Country B company and exchanges all shares of the United States corporation for shares of the new company. Because the former shareholder holds all the stock of the foreign parent and the group has no substantial business activities in Country B, section 7874 would generally treat the Country B parent as a domestic corporation, so the Corporate Inversion would not change the group's United States tax status.
Common misconception
Myth: Placing a new foreign parent above a US company moves the group outside the US tax net.
Reality: Under section 7874, a foreign parent at least 80 percent owned by former shareholders of the domestic corporation is generally treated as domestic absent substantial business activities in the foreign country.
Frequently asked questions
What is a corporate inversion?
A Corporate Inversion is a restructuring in which a domestic parent company becomes a subsidiary of a foreign parent, usually through a share exchange, so that the group's top company is organised abroad.

Corporate Inversions remain legally possible, but United States section 7874 treats the foreign parent as domestic at 80 percent continuing ownership and sets a taxable income floor at 60 percent, unless the group has substantial business activities abroad.
