Social Security Reserves and Sources of Income

Good article which outlines how Social Security invests its current $2.9 trillion in excess reserves.

Highlights :

Social Security received generated $957.5 billion in revenue in 2016

Sources of income for Social Security :

- Payroll (FICA) taxes : 87.3 percent

- Taxation of Social Security benefits : 3.4 percent

- Interest from bonds (excess reserves) : 9.2 percent

The problem is the program expects to begin paying out more in benefits than it's generating in income beginning in 2022.
