I just turned 70 in March. I've been receiving a spousal benefit since 66. I applied to receive my own benefit starting March 1st. However, I received a phone call from Social Security about getting retroactive benefits back to Sept 2020. I don't see any benefit to this. I would get a llump amount but about $102 less in benefits. Am I missing why any healthy person would take that option?

Hi. There are circumstances (e.g. poor health with no potential for survivor payments) where it might be advantageous to opt for a retroactive payment in lieu of a higher ongoing monthly benefit rate, but in most cases opting for the higher monthly rate is a better choice. I don't have enough information about your situation to be able to advise you, but my guess is that you're likely making a good choice by waiting until the month you reach age 70 to switch to your own benefits.

Best, Jerry
