The surtax would impact around 345,000 taxpayers, roughly 0.2 percent of taxpayers, or one in 500 of them. Those people would pay on average an additional 2.1 percent of their overall income, or just over 1/50th of that overall income, in taxes.
In a majority of states, only one-tenth of one percent, or one in 1,000 taxpayers, would pay this surtax.
And how many people would benefit from the payroll tax cut? According to the group, around 113 million tax filing units — either single workers or families that include more than one worker — would see their payroll tax cut extended. That’s a lot of people — well over 113 million workers, in fact.
