Q. I retired as a Department of Defense employee with 30 years and 8 months of CSRS. I am 71 years old. I want to return back to work at the same office with a lower GS position. Let’s say GS-4 or 5. I retired as a GS 9 step 10. How will my retirement pay be affected?
A. Your retirement annuity wouldn’t be affected; however, the salary of your new position would be reduced by the amount of your annuity. If the difference between your annuity and the salary of that new position was too small, you could end up working for next to nothing.
