Someone who makes $118,500 in the 2015 tax year pays $7,347 toward Social Security, and the person's employer contributes the same amount, notes the federal government. The taxes go toward the Social Security Old-Age, Survivors and Disability Insurance program. The annual limits paid into the program also determine someone's Social Security benefit later in life when a taxpayer retires.
The upper limit of $118,500 for contributions and benefits in 2015 rose from $117,000 the year before, says the Social Security Administration. Social Security taxes on wages began to be collected in 1937. The maximum contribution limit rose above $100,000 for the first time in 2008.
