## What Is an Anti-Inversion Rule?

An Anti-Inversion Rule is a corporate tax provision which restricts benefits when a domestic company is placed beneath a foreign parent, as national law defines.

*Also known as: Section 7874 Rules, Inversion Rules.*

## How Anti-Inversion Rule works

An Anti-Inversion Rule applies when a foreign corporation acquires substantially all the properties of a domestic corporation and the former shareholders keep a large stake in the new foreign parent, and the main United States version, Internal Revenue Code section 7874, then either treats the foreign parent as domestic or sets a floor on taxable income. Under section 7874(b), the foreign parent is treated as a domestic corporation for the purposes of the Internal Revenue Code where former shareholders hold at least 80 percent of its stock by vote or value. Where the stake is at least 60 percent but below 80 percent, the domestic company is an expatriated entity whose taxable income cannot fall below its inversion gain during an applicable period ending 10 years after the last acquisition. Neither consequence applies where the group has substantial business activities in the foreign country, measured by Treasury regulations as at least 25 percent of group employees, compensation, assets and income located there; these thresholds are specific to United States law, and other countries use different measures.

## Anti-Inversion Rule vs Corporate Inversion

Unlike a corporate inversion, which is the transaction moving a parent company abroad, an Anti-Inversion Rule is the statutory response determining whether the new foreign parent keeps domestic status or faces restricted tax treatment.

## Example

Illustrative example: A United States founder relocating abroad contributes all shares of a United States corporation to a newly formed company in Country B with no employees or operations there. Because the founder, as former shareholder, holds all the stock of the new foreign parent and the group lacks substantial business activities in Country B, section 7874(b) would generally treat the Country B company as a domestic corporation for United States tax purposes.

## Common misconception

**Myth:** Moving a US company under a newly formed foreign holding company changes the group's US tax status once the founder lives abroad.

**Reality:** Under section 7874, a foreign parent at least 80 percent owned by former shareholders of the domestic corporation is generally treated as domestic unless the group has substantial business activities abroad.

## Frequently asked questions

### What is the 80% test under section 7874?

Under the section 7874 80 percent test, a foreign acquiring corporation is treated as a domestic corporation when former shareholders of the acquired domestic corporation hold at least 80 percent of its stock by vote or value, absent substantial business activities abroad.

### What happens when a corporate inversion is caught by section 7874?

A corporate inversion caught by section 7874 leads to domestic treatment of the foreign parent at 80 percent ownership or more, or, between 60 and 80 percent, to a taxable income floor equal to inversion gain for an applicable period.
