Psst, taxes go up in 2013 for 163 million workers

WASHINGTON (AP) - President Barack Obama isn't talking about it and neither is Mitt Romney. But come January, 163 million workers can expect to feel the pinch of a big tax increase regardless of who wins the election.

A temporary reduction in Social Security payroll taxes is due to expire at the end of the year and hardly anyone in Washington is pushing to extend it. Neither Obama nor Romney has proposed an extension, and it probably wouldn't get through Congress anyway, with lawmakers in both parties down on the idea.

Even Republicans who have sworn off tax increases have little appetite to prevent one that will cost a typical worker about $1,000 a year, and two-earner family with six-figure incomes as much as $4,500.

Why are so many politicians sour on continuing the payroll tax break?

Republicans question whether reducing the tax two years ago has done much to stimulate the sluggish economy. Politicians from both parties say they are concerned that it threatens the independent revenue stream that funds Social Security.

They are backed by powerful advocates for seniors, including AARP, who adamantly oppose any extension.

"The payroll tax holiday was intended to be temporary and there is strong bipartisan support to let that tax provision expire," said Sen. Orrin Hatch of Utah, the top Republican on the Senate Finance Committee. "The continued extension of a temporary payroll tax holiday has serious long-term implications for Social Security and, frankly, it's not even clear that it has helped to boost our ailing economy."

The question of renewing the payroll tax cut has been overshadowed by the expiration of a much bigger package of tax cuts first enacted under President George W. Bush. The Bush-era tax cuts also expire at the end of the year, and Congress is expected to try to address them after the election, in a lame-duck session.

The payroll tax cut could become part of the mix in negotiations that could go in many directions. But lawmakers in both political parties say they doubt it.

"I think there's a growing consensus that Congress and the president can't continue to divert such a critical revenue stream from Social Security," said Rep. Kevin Brady of Texas, a senior Republican on the tax-writing House Ways and Means Committee. "I think more and more Americans understand that that payroll tax cut, while politically appealing, is endangering Social Security."

Before he was named as Romney's running mate, Rep. Paul Ryan, R-Wis., disparaged the payroll tax cut, calling it "sugar-high economics" that wouldn't promote long-term growth.

Social Security is funded by a 12.4 percent tax on wages up to $110,100, rising to $113,700 in 2013. Half is paid by employers and the other half is paid by workers. For 2011 and 2012, Congress and Obama cut the share paid by workers from 6.2 percent to 4.2 percent.

A worker making $50,000 saved $1,000 a year, or a little more than $19 a week. A worker making $100,000 saved $2,000 a year.

The beauty of the tax cut is that is shows up in weekly paychecks, giving workers more money to spend or save. The downside is that some workers may not notice a $19-a-week increase in pay, making them unlikely to credit the politicians who made it happen.

Under the law, Congress is reimbursing Social Security for the lost revenue, estimated at $103 billion in 2011 and $112 billion in 2012. But Congress didn't cut spending or raise other taxes to offset the lost revenue, so the payroll tax cut is being financed with borrowed money, adding to the national debt.

Democrats are more willing to defend the tax cut, saying it helped prop up the economy during a rough stretch while providing what amounted to a 2 percent pay increase to millions of middle-income workers. But they, too, are concerned about maintaining Social Security's source of revenue.
