“The new data in today’s report makes clear that the United States needs to replicate that success or risk being outcompeted by our foreign rivals,” Jim Pinkerton, a former aide to Presidents Reagan and George H.W. Bush and RATE co-chairman, said in a statement. “Our corporate tax rate has remained at a standstill while our competitors have lowered theirs by 35 percent. We can’t afford to wait any longer.”
The study found that the foreign rate reductions “were prompted in large part by the inexorable forces of globalization and increasing international tax competition as countries attempt to retain and attract highly mobile capital investments by large U.S. and foreign multinational corporations.”
Those declines, the study said, make it more attractive for U.S. companies to invest abroad and discourages foreign investment here. Over a 25-year span, the corporate tax rate disparities could lower real wages by a percent.
Still, the study’s estimated long-term GDP drop amounts to about 0.1 percent a year, though Ernst & Young also says that most of the impact would be in the first decade. For comparison’s sake, the Congressional Budget Office has estimated that sequestration could cause a 0.6 percent drop in GDP for fiscal 2013.
