Q. I am under FERS. If the human resources office states that I did not pay into the retirement system from 1985 to 1986 and OPM says deductions were made into the retirement system, when the retirement package is submitted and if OPM was wrong in its initial determination, will I be afforded the opportunity to make that payment after the retirement package has been submitted?
A. Yes. You can do that at any time up to the point that OPM finalizes your annuity.
