America is one of the few nations to tax citizens who live and work abroad. Indeed, no other industrialized nation imposes a second layer of tax on its expatriates. Senator Jim DeMint (R-SC) has introduced legislation, the Working American Competitiveness Act (S. 3496), to eliminate the worldwide reach of the IRS. By creating a territorial system for labor income, the DeMint legislation will put American workers and U.S.-based multinationals on a level playing field with competitors from other nations. This is a welcome move, particularly since American expatriates were just hit with a tax hike.
