Bernie Sanders would raise taxes on corporations by almost $4trillion; his plan would generate more revenue than any otherDemocratic presidential candidate's proposal, according to newestimates from the Tax Foundation.

The major Democratic presidential candidates all agree that the2017 Republican-backed tax overhaul, which lowered the corporaterate to 21 percent, from 35 percent, went too far. They differ,however, on how much to raise the rate. Proposals range from 25percent to 35 percent, plus additional surtaxes and reducedcorporate tax breaks that add to the total levies companies wouldface.

Sanders is proposing a 35 percent corporate rate and economicdepreciation for investments that would raise taxes on corporationsby $3.87 trillion over a decade, according to the figures releasedWednesday. At the bottom end of the spectrum, Amy Klobuchar'sproposal would impose a 25 percent rate that would raise $716billion over 10 years.
