Analysis: Trump's plan would cut taxes up to $5.9 trillion

Donald Trump’s tax reform plan would amount to either a $4.4 trillion or a $5.9 trillion tax cut, according to a new outside analysis, depending on whether a small business tax cut is included in the plan. The Trump campaign hasn’t made clear whether that provision is included.

The Tax Foundation, a nonprofit think tank, found that Trump’s plan would also spur economic growth by reducing tax rates and boosting the rewards for investing and saving. As a result, in a “dynamic analysis” that takes into account the revenues from that economic growth, Trump’s plan would cost the Treasury less: Either $2.6 trillion or $3.9 trillion, depending on whether the small business tax cut is included.
