Title 26 › Subtitle F — Procedure and Administration › CHAPTER 80 — GENERAL RULES › Subchapter C — Provisions Affecting More Than One Subtitle › § 7874
Makes certain U.S. companies pay U.S. tax when a foreign company effectively takes them over and the deal is meant to move the parent abroad. If a U.S. company or related U.S. persons become an "expatriated entity" under a plan where a foreign firm buys nearly all the U.S. business after March 4, 2003, then that expatriated entity’s taxable income for any year that falls during the "applicable period" cannot be less than its "inversion gain." An expatriated entity is the U.S. corporation or partnership bought and U.S. persons related to it. A "surrogate foreign corporation" is a foreign firm that, after the deal, (1) bought substantially all the U.S. assets, (2) is at least 60% owned by the former U.S. owners, and (3) has little business activity in the foreign country compared with the whole group. If the foreign firm would meet those rules using 80% instead of 60%, it is treated as a U.S. company for tax purposes. "Applicable period" runs from the first date assets are bought through 10 years after the last such purchase. "Inversion gain" is income or gain from transfers or licenses of stock or assets during that period, and it includes transfers to related foreign persons. Most tax credits can’t fully reduce the tax on inversion gain; only the credit under section 901 is treated normally, and others apply only after comparing inversion gain times the top tax rate in section 11(b). If the expatriated entity is a partnership, the rules apply to each partner; each partner’s inversion gain is the partner’s share plus any gain from transferring the partner’s interest to the foreign buyer. Certain ownership and transfers are ignored for tests (for example, stock held by group members or stock sold in a related public offering). Actions within a 4‑year window that start up to 2 years before ownership rules are met are treated as part of the plan. The law extends the IRS assessment period: for pre-inversion years the IRS has at least 3 years after the taxpayer tells the IRS about the acquisition to assess deficiencies. Treaties do not allow avoiding these rules. The Treasury must write rules to carry out the law and to stop people from avoiding it by using related parties, intermediaries, or tricks to change group membership.
