"What came out of the compromise was the idea of the payroll tax holiday, which, frankly, a huge number of economists and other experts had been talking about over the last two years with a lot of support in both political parties," said Larry Summers, Obama's chief economic adviser.
The United Auto Workers endorsed the deal, saying, "Working families will likely spend this money in their local communities, creating jobs and stimulating overall growth."
The payroll tax cut is part of a larger package negotiated by Obama and GOP lawmakers to extend a sweeping array of Bush era tax cuts that expire at the end of the month. Some Democratic lawmakers have balked at the plan, saying it is tilted too much in favor of the rich.
The payroll tax cut would provide relief to any worker earning a wage. It would replace Obama's Making Work Pay tax credit, which has provided modest increases in most workers' paychecks for the past two years.
The payroll tax credit would be more generous to individuals making more than $20,000 and married couples making more than $40,000. For those making less, the payroll tax cut would be less than the Making Work Pay credit.
Making Work Pay, which expires at the end of the year, gives workers a tax credit of 6.2 percent of their wages, but it is capped at $400 for individuals and $800 for couples. The credit is phased out for individuals making more than $75,000 and couples making more than $150,000.
A worker would have to make $20,000 in wages for the payroll tax cut to equal the $400 Making Work Pay tax credit; couples would have to make $40,000.
At the wealthy end of the pay scale, workers making $106,800 — the maximum amount of wages subject to Social Security taxes — would see their payroll taxes reduced by $2,136. That worker's spouse could also get a payroll tax cut of up to $2,136, if he or she makes at least $106,800.
