Hi Larry,
I'll be turning 70 in September 2017. I still have a full-time job and plan to continue working after turning 70. Two questions: 1.) Do I need to contact SS prior to my turning 70 or after turning 70 to receive the full percentage I'm entitled to? Should I NOT take the 'retro' payment, and instead elect to keep my full retirement?

Hi,

If you haven't yet filed for benefits, you will need to file an application in order to start receiving payments. On the other hand, if you've previously filed for and suspended your benefits, your payments should start up automatically when you turn age 70.

With regard to whether or not you should take the retroactive payment option, that is a personal decision. However, Larry recommends not taking the retroactive payment option and waiting until age 70 in most cases (https://www.forbes.com/sites/kotlikoff/2015/05/27/dont-let-social-securi...).

The best course of action often depends on your individual circumstances, however, so you may want to consider running the maximization software available on this website in order to compare your choices.

Best, Jerry
