Social Security Questions? Ask a Social Security Expert
Hi, my name is ***** ***** I can help. Unfortunately, once your reach your full retirement age you longer receive any work credits from that point on even though you do still have to pay the FICA (Social Security) tax under federal law. Once you reach your full retirement age, the only way to get an increased benefit is to delay receiving benefits, in which you get "delayed retirement credits" for not taking benefits at your full retirement age.
I hope this answers you question, and sorry I do not have a better answer for you. Please let me know if I can clarify anything or answer any additional questions.
