Social Security could pay full benefits until 2059 if taxable payroll kept pace with GDP: AARP report

Social Security 's taxable payroll, which provides most of the revenue for the program that pays monthly benefits to millions of Americans, has fallen as a share of gross domestic product over the past four decades, according to a new report from the AARP Public Policy Institute. Had payroll tax revenue kept up with GDP, the program could pay full benefits until 2059, according to the research — an additional 25 years beyond the latest projected depletion date of 2034 for the program's combined funds. The AARP Public Policy Institute provides policy research, analysis and development at AARP, a nonprofit, nonpartisan organization that represents Americans ages 50 and over.
