Dubay added that, while TPC is the “industry standard” on tax data, this particular report “hinders the debate on tax reform because lawmakers and the public need accurate information to make good decisions.”
But the center, a joint venture of the Urban Institute and the Brookings Institution, has stood by its main point – that Romney’s plan doesn’t add up.
As TPC notes, the former Massachusetts governor has called for an across-the-board income cut rate of 20 percent; keeping current rates on capital gains for the highest earners and eliminating them for the middle-class; and getting rid of the estate tax and the Alternative Minimum Tax.
TPC says meeting those goals while taking in the same amount of revenue, another goal of Romney’s, “would then imply increased tax burdens on other taxpayers, a necessary but perhaps unintended consequence.”
The back-and-forth comes as the TPC study continues to be cited by the Obama campaign, and as Romney has come under some criticism for not being more upfront about what tax breaks he would like to limit in a reform effort.
