Q. How can a FERS employee change their retirement date if they’ve already declared one?
A. You need to inform your supervisor (and your personnel office if you have already submitted your retirement application). Usually, changing your retirement date won’t be a problem. However, if your position is being eliminated as of a certain date or your agency has already committed itself to someone who will fill your position, then it can refuse your request to change the date of your retirement. The reason for its refusal will have to be presented to you in writing.
