The United States may be about to implement a border adjustment tax. The Republican Party, now in control of the legislative and executive branches, views a BAT – which would effectively subsidize US exporters, by giving them tax breaks, while penalising US companies that import goods – as an important element of corporate-tax reform. They claim that it would improve the US trade balance, while boosting domestic production, investment, and employment. They are wrong.

The truth is that the Republicans’ plan is highly problematic. Along with other proposed reforms, the BAT would turn the US corporate income tax into a tax on corporate cash flow (with border adjustment), implying far-reaching consequences for US companies’ competitiveness and profitability.
