“Putting all the provisions together, the Center on Budget and Policy Priorities estimates that the deal will lift about 400,000 children out of poverty, and make another 3 million less poor, in its first year. By 2025, it will be keeping 500,000 children a year out of poverty. The Tax Policy Center finds that the bulk of the tax cut will go to families earning $20,000 to $40,000 a year, with most families in the bottom fifth of the income scale getting a tax cut. Because of the business tax cuts, the total package winds up concentrating its benefits at the bottom and at the very top of the income scale.
While nothing to sneeze at, this is a far cry from the roughly 3 million children that would been lifted out of poverty in 2022 if the 2021 expansion of the credit had been extended. It is a dramatically more modest step. It also takes as a given that the credit will not be available to families with zero earnings, a key disagreement between Democratic and Republican legislators on which the latter have shown no flexibility.”
