evidence: Biden said in a March interview with ABC News that this increase would raise $230 billion, which is about double the Tax Policy Center’s estimate for lifting the rate on those earning about $400,000 a year. Such a move would capture some people whose top rate is currently 35% and all of those in the 37% bracket, said Howard Gleckman, senior fellow at the center. [...] Those earning more than $1 million annually would have to pay higher taxes on capital gains, which typically make up the largest share of income for the wealthy, under Biden’s campaign proposal. [...] These business tax hikes make up the largest component of Biden’s campaign proposal, raising about $1.3 trillion in revenues over a decade.
