The tax is applied to the first $110,100 of a worker's wages, a level that increases each year with inflation. For 2011 and 2012, the tax rate for employees was reduced to 4.2 percent, but is scheduled to return to 6.2 percent in January.
The payroll tax rate was only 2 percent in 1937, the first year Social Security taxes were levied. It did not surpass 6 percent until 1962.
Even with low tax rates, Social Security could afford to pay benefits in the early years because there were more workers paying the tax for each person receiving benefits than there are today. In 1960, there were 4.9 workers paying Social Security taxes for each person getting benefits. Today, there are about 2.8 workers for each beneficiary, a ratio that will drop to 1.9 workers by 2035, according to projections by the Congressional Budget Office.
About 56 million people now collect Social Security benefits, and that number is projected to grow to 91 million in 2035. Monthly benefits average $1,235 for retired workers and $1,111 for disabled workers. Social Security provides most older Americans a majority of their income. About one-quarter of married couples and just under half of single retirees rely on Social Security for 90 percent or more of their income, according to the Social Security Administration.
"Social Security is what's carrying me," said Neta Homier, a 79-year-old retired hospital worker from Toledo, Ohio. "There's no way I would have made it without it. The kids, they're on their own, now, and I'm not going to be a burden for them. That's what it would have been if I hadn't had Social Security."
Homier said she started receiving Social Security when she was 63 and now gets about $800 a month, after her Medicare premiums are deducted. She said her father died at 51, so he never received Social Security, and her mother died at 71 and collected benefits for only a few years.
"It's definitely worth it," she said.
At 52, Anthony Riley of Columbus, Ohio, has a different perspective. Riley said he has a private retirement account because he worries that Social Security won't provide adequate benefits throughout his retirement.
"I use to think that it was worth paying for your Social Security, but now I don't think so," Riley said. At 22, Mackenzie Millan of Los Angeles has even greater doubts about whether Social Security will be a good deal for her.
"The money that I put aside now, it's not like that money is going to be waiting for me. That money is going toward someone else," the recent college graduate said. "If I wanted Social Security 50 years from now, when I wanted to retire, I would have to hope that someone else is still working and putting money aside in their paychecks to pay for my Social Security at that point."
