WASHINGTON, April 1, 2015—President Obama has just sent Congress a bill that would replenish the Highway Trust Fund through a 14 percent tax on offshore corporate profits. There is bipartisan support for even deeper tax cuts for companies that have stockpiled profits in tax havens, where they remain untaxed until "repatriated" to the United States. A new report, to be released April 1 by the Center for Effective Government and the Institute for Policy Studies, reveals why such tax breaks would be dangerously short-sighted.
