Middle-class households - defined as those making between roughly $49,000 and $86,000 a year - will see their tax bills drop by about $930, the Tax Policy Center calculates. That will lift their after-tax incomes by 1.6 percent.
The richest 1 percent, meanwhile, will save $51,140, lifting their after-tax incomes by 3.4 percent, or more than twice as much as the middle class.
