Crunch the numbers this way and the working poor get screwed

The appropriately named Ryan Grim reports:

The tax deal reached between President Obama and congressional Republicans could mean a higher tax bill for roughly one in three workers as a result of the Social Security tax cut Republicans pushed as a replacement for the current Making Work Pay tax credit.

The Making Work Pay credit gives workers up to $400, paid out at 8 percent of income, meaning that anybody making at least $5,000 gets the full amount -- and gets as much as anybody else. Its replacement knocks two percentage points off the payroll tax cut, meaning a worker would need to make $20,000 to get a $400 break. Of the nation's roughly 150 million workers, around 50 million make less than $20,000 and will see at least some increase as a result.

Additionally, roughly a quarter of 20 million state and local workers pay no payroll tax, because they have a separate pension system. Some of those workers with children will benefit from the extension of other tax credits, but overall will have less money in their pocket.
