Fed OASDI/EE stands for Old-Age, Survivors, and Disability Insurance (OASDI) better known as Social Security. This is a mandatory 6.2% tax based on taxable gross earnings.
The Social Security Administration sets the limit for OASDI each year.
Once an employee reaches the annual maximum OASDI earnings no further deductions will be taken in that calendar year. Deductions resume in the next calendar year with the December earnings paid in January. IRS.gov publishes the limit annually: https://www.irs.gov/taxtopics/tc751
1. Why did my OASDI deduction stop?
Social Security (OASDI) has a taxable wage base that is subject to change each year. Once the employee reaches the taxable wage base OASDI will no longer be withheld from their check for the remainder of the calendar year.
