Before President Donald Trump paused some new tariffs that he unveiled on April 2, several economic groups estimated that tariffs he has announced this year could raise between roughly $2 trillion and more than $4 billion in federal revenue over a 10-year period.

Basic economics shows the revenue would be at most half as much — and probably less than that. “We’re going to raise about $100 billion with the auto tariffs alone … In addition, the other tariffs are going to raise about $600 billion a year, about $6 trillion over a 10-year period.”

Peter Navarro, former White House advisor, claims that Donald Trump's proposed tariffs could generate up to $6 trillion in revenue over the next decade. This would mark the largest tax increase in U.S.
