Section 7874 Anti-Inversion Rules: 60%/80% Ownership Tests and the Substantial Business Activities Safe Harbor
Section 7874 imposes a 10-year inversion-gain floor when former U.S. shareholders own 60-80% of a new foreign parent and reclassifies the parent as a domestic corporation at 80%. The only escape is the substantial business activities safe harbor, which requires clearing a 25% bright-line threshold on employees, tangible assets, and gross income in the foreign country.
