The first tax inversion in 1983 was followed by small waves of subsequent inversion activity, including two inversions completed by Transocean. Significant media and political attention focused on transactions made by U.S. multinational corporations that were primarily designed to reduce U.S. corporate income taxes. As a result, the U.S. government took several actions to limit inversion activity. The Tax Cuts and Jobs Act of 2017 (TCJA) significantly lowered U.S. corporate tax rates and one expected impact of TCJA is a reduction of inversion activity. Students use the Transocean inversions to understand the reasons why companies complete a tax inversion and how the U.S. tax code affects inversion activity. Students also learn about the structure of inversion transactions and how they have changed over time as the U.S. government attempted to limit them. Students also assess the tax and economic impacts of inversion transactions to evaluate tax policy.
