Q. I am planning to retire at age 60 from the Postal Service after 34 years.
I also have five years of military service, which I never paid back. I have 31 quarters in Social Security. If I decide to work after I’m 63 to get the 40 quarters, will it affect the amount of my CSRS retirement?
A. No. OPM will check only once with the Social Security Administration: at age 62, if you are already retired, or on the day you retire, if it is at or after age 62.
