The Tax Foundation analysis of Bobby Jindal’s tax plan:

• Governor Jindal’s tax plan would substantially lower individual income taxes, eliminate the corporate income tax, and repeal a number of complex features in the current tax code.
• Governor Jindal’s plan would cut taxes by $11.3 trillion over the next decade on a static basis. However, the plan would end up reducing tax revenues by $9 trillion over the next decade when accounting for economic growth from increases in the supply of labor and capital.

So let’s summarize the four plans examined by the Tax Foundation model:

• The Jeb Bush plan would lose $1.6 trillion over a decade (with economic feedback),  lead to a 10% higher GDP over the long-term, and boost income in the bottom fifth by 10%, the middle fifth by 13%,the top fifth by 10%, and the top one percent by 16%.
• The Marco Rubio plan tax plan would lose $1.7 trillion over a decade (with economic feedback), lead to a 15% higher GDP over the long run, and boost income in the the bottom fifth by 40%, the middle fifth by 16%,the top fifth by 18%, and the top one percent by 28%.
• The Donald Trump plan would lose $10 trillion over a decade (with economic feedback), lead to an 11% higher GDP over the long term, and boost income in the the bottom fifth by 11%, the middle fifth by 19%,the top fifth by 21%, and the top one percent by 27%.
• The Rand Paul plan would lose $1 trillion over a decade (with economic feedback, lead to a 9% higher GDP over the long term, and boost average incomes by 16%.
• The Jindal plan would lose $10 trillion over a decade with economic feedback, lead to a 14% higher GDP over the long run, would boost income in the the bottom fifth by 8%, the middle fifth by 15%,the top fifth by 22%, and the top one percent by 26%.

One important caveat (other than the vagaries of dynamic scoring) is that the TF model does not factor the “fiscal costs of higher interest payments, as well as the macroeconomic effects of the spending reductions needed to bring the budget into balance.” Let me also add that one other thing the TF model shows is that personal income tax cuts tend to have the biggest revenue loss and the least GDP bang for the trillion bucks.
