Both candidates’ tax plans have been brought up during the vice presidential debate.

The Tax Foundation, a conservative D.C. think tank created to argue for lower taxes on the wealthy and corporations, found that Trump’s tax plan would raise the national debt over 10 years by $4.4 trillion and $5.9 trillion on a static basis. The huge $1.5 trillion range in their estimate was required because Trump’s plan provided so few details.

This increase in the federal debt would be between about 2 and 2.5 percent of the entire U.S. gross domestic product over the 10-year period.

Trump’s plan would be an enormous boon to the wealthy, increasing the after-tax income of the richest 1 percent between 10.2 percent and 16.0 percent.

The Tax Foundation estimated that Hillary Clinton’s tax plan would reduce the national debt over the next ten years by $498 billion on a static basic.

Clinton’s plan would reduce the after-tax income of the top 1 percent by 1.7 percent when judged on a static basic, or perhaps more using the Tax Foundation’s own dynamic estimate.
