who contributes money to the social security trust fund
Social Security Trust Fund Social Security benefits are paid from a combination of social security payroll taxes paid by current workers and interest income earned by the Social Security Trust Fund. According to the projections of the Social Security Administration, the Trust Fund will continue to show net growth until 2022[17] because the interest generated by its bonds and the revenue from payroll taxes exceeds the amount needed to pay benefits. After 2022, without increases in Social Security taxes or cuts in benefits, the Fund is projected to decrease each year until being fully exhausted in 2034. At this point, if legislative action is not taken, the benefits would be reduced.[18]
