Surprise: Fiscal cliff deal hurts middle class

An analysis of the so-called fiscal cliff deal reveals that earners making just $30,000 will take a bigger hit on their pay than those earning between $200,000 and $500,000:

Earners in the latter group will pay an average 1.3 percent more - or an additional $2,711 - in taxes this year, while workers making between $30,000 and $200,000 will see their paychecks shrink by as much as 1.7 percent - or up to $1,784 - the D.C.-based think tank reported.

Overall, nearly 80 percent of households will pay more money to the federal government as a result of the fiscal cliff deal.

"The economy needs a stimulus, but under the agreement, taxes will go up in 2013 relative to 2012 - not only on high-income households, as widely discussed, but also on every working man and woman in the country, via the end of the payroll tax cut," said William G. Gale, co-director of the Tax Policy Center.

"For most households, the payroll tax takes a far bigger bite than the income tax does, and the payroll tax cut therefore - as [the Congressional Budget Office] and others have shown - was a more effective stimulus than income tax cuts were, because the payroll tax cuts hit lower in the income distribution and hence were more likely to be spent," he added.
