Okay so chances are you didn't pay the penalty for not buying the years within the first 2 years of starting your FERS job. The penalty isn't assessed until you hit year 3 so it technically can be almost 3 years if you pay a day before hitting the 3 year mark. If that's the case I am shocked that wan't discovered as normally OPM will calculate the interest penalty along with the original balance of 3% of your total base pay for the years you are buying back to apply to FERS.I bought my military time back about 6 months before I offically retired from FERS.
I worked FERS for 8 years.
HR and ABC helped me throughout the process.
Let us know what they are talking about regarding rolling over the 16k? I assume the withdraw means you get your 16k minus 20% penalty and lose out on buying back those years. Not sure though.
