What Is Tax
OASDI tax is a mandatory payroll tax that funds the Social Security program, also known as Social Security. The IRS collects OASDI tax and then passes this money along to the Social Security Administration, which pays out benefits that help support people following retirement, a disability or the death of a spouse or parent.
The OASDI tax rate is 12.4 percent, split between employers and employees, with each party paying 6.2 percent. People who are self-employed must pay the entire 12.4 percent tax rate.
