Social Security Primer

"Social Security provides monthly cash benefits to retired or disabled workers and their family members, and to the family members of deceased workers. Among the beneficiary population, almost 83% are retired or disabled workers; family members of retired, disabled, or deceased workers make up the remainder. In December 2018, approximately 62.9 million beneficiaries received a total of $84.4 billion in benefit payments for the month; the average monthly benefit was $1,342.

An estimated 94% of workers in paid employment or self-employment are covered, and their earnings are subject to the Social Security payroll tax. Employers and employees each pay 6.2% of covered earnings, up to an annual limit on taxable earnings ($132,900 in 2019)...."
