The Obama administration is ready to follow through on campaign promises to crack down on U.S. companies that “ship jobs overseas.” The administration announced this weekend that it would seek to raise taxes on the so-called active earnings of U.S.-owned affiliates abroad. According to a front-page story in this morning’s Wall Street Journal:

Under current law, U.S. companies can defer taxes indefinitely on the many of the profits they say they have earned overseas until they “repatriate” that money back to the U.S. The administration seeks to sharply limit the tax deductions that companies taking advantage of deferral can take.

Of course, there is a perfectly good reason why we don’t tax what U.S. companies earn and keep abroad: those companies are already paying taxes in the countries where their affiliates are located, and at the same rates that apply to multinationals from other countries competing in the same markets.

As I pointed out in a Cato Free Trade Bulletin in January, locating affiliates in foreign markets is now the chief way that U.S. companies reach new customers outside the United States. If we sock them with the relatively high U.S. corporate rate, U.S. companies will be less able to compete against German and Japanese multinationals in the same markets who need only pay the (almost always) lower corporate rate assessed by the host country. And as I noted in January, any jobs created at affiliates abroad tend to promote more employment at the parent company back in the United States.

This demagogic grab for more revenue will only cripple the ability of U.S. companies to expand their sales in global markets, putting in jeopardy the U.S.-based jobs that support their foreign affiliates.
