In December 2010, Congress approved a temporary 2 percentage point reduction in the Social Security payroll tax rate for employees and the self-employed in 2011 as part of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 ( P.L. 3765 ) to extend the payroll tax reduction for workers for two months (through February 2012). The Social Security payroll tax for workers in effect through December 2012 is 4.2% (rather than 6.2%).

For example, the annual Social Security withholding for a worker earning the average wage in 2011 (an estimated $44,687) was lower by about $894. The annual Social Security withholding for a worker earning the maximum taxable wage ($106,800 in 2011) was lower by $2,136.

Despite the general revenue transfers to protect the trust funds from a loss of payroll tax revenues, some observers have expressed concern about the potential impact of the temporary reduction in the payroll tax for employees and the self-employed on Social Security's long-term finances. These observers point out that, although the payroll tax reduction is temporary, the possibility remains that Congress could continue to extend the payroll tax reduction or make the payroll tax reduction permanent in response to political or other pressures without providing transfers from general revenues. Opponents maintain that the general revenue transfers to the Social Security trust funds introduce an element of general revenue financing to the Social Security program, signaling a departure from the self-financing mechanism that has been in place since the program's enactment in the 1930s. Views Among Supporters

Some observers support the temporary reduction in the Social Security payroll tax on the basis that it will stimulate economic recovery and create jobs at a time when the United States continues to experience high rates of unemployment. They maintain that the immediate increase in take-home pay will spur additional consumer spending, increasing the demand for products and services, which in turn will increase production and employment. Temporarily reducing Social Security payroll taxes is a policy option that has been advanced in various forms by recent deficit reduction commissions, among others, as an effective way to stimulate economic growth and job creation consistent with long-term fiscal discipline.
