If I elect to change my retirement coverage under the FERCCA, can I get a refund of the service credit deposit I made and receive the actuarial reduction instead?

CFR · 2024-01-01 · US · Title 5

No, the FERCCA allows OPM to reduce an annuity by an actuarial reduction only for the deposit amount that remains unpaid.
