The United States recently overhauled its international tax system, nominally moving from a worldwide to a territorial system. In reality, however, the new tax law is nuanced and extremely complex, incorporating both territorial and worldwide elements. In addition, the adoption of a participation exemption regime required U.S. Congress to adopt new anti-abuse rules, and to revamp certain existing anti-abuse rules, in order to prevent income shifting. The course will try to untangle some of these complexities, by exploring U.S. international tax anti-avoidance doctrines in light of the new law. We will discuss general US anti-avoidance policies as well the various particular mechanisms to fight both inbound and outbound tax avoidance, including CFC rules, LOB provisions, the new rules relating to Global Intangible Low-Taxed Income (GILTI), the new anti-mismatch rules, the new Base Erosion Anti-abuse Tax (BEAT), and anti-conduit financing rules.
