Q: Are the Federal Employees Retirement System and special retirement supplement annuities subject to federal income tax? If they are, and your FERS annuity is greater than $15,000, will the special retirement supplement be reduced?
A: The special retirement supplement is subject to federal (and, where applicable, state) taxes. However, your special retirement supplement would only be reduced if you had earnings from wages or self-employment. The Social Security earnings test doesn’t count other sources of income, such as annuities.
