Fourteen years ago, Congress set out to remedy a basic unfairness in the tax code. The tax that funds Medicare, because it’s aimed mainly at wages, hits even the poorest American workers. But the wealthy could easily avoid paying their share. So lawmakers created a new type of Medicare tax to capture the kinds of income the rich often enjoy: interest, dividends and capital gains from investments…. We identified 17 people who, in the first six years of the law, 2013 through 2018, each shielded at least $1 billion in capital gains from the tax. Together, this small group, by collectively exempting more than $35 billion, saved about $1.3 billion in taxes.
