I turned 66 in March 2017. When I was filling out the on-line application, I was asked if to start benefit on 3/1/2017. Do I make the application effective March or April?

Hi,

If you want benefits to begin effective with your full retirement age you should choose March, unless you happen to have been born on March 1st, in which case you would choose February.

You may want to consider running the maximization software available on this website first, though. You may have better filing options available to you.

Best, Jerry
