When the jct, the joint committee on taxation, released a dynamic estimate of how much growth they expect this tax plan to generate. And its a lot less than republicans were hoping for. The jct estimating the tax plan would generate 407 billion in additional revenue over the next decade and that is not enough to cover the 1. 4 trillion cost of this tax plan. The Senate Finance committee putting out a statement saying that this analysis is curious and deserves further scrutiny and they emphasized that the final version of the tax bill is not yet complete it is still being hammered out on the senate floor. Another important thing to note is that the jct assumed a very aggressive response by the Federal Reserve to a strengthening economy. That is also very different from what we have been hearing from jay powell and janet yellen over the next few days. So even if you discount that, however, there is no way, according to the jcts analysis, that the republican tax plan will pay for itself.
