I have tried to find out on the SSA website, and others, if there is some kind of "reward/penalty" to waiting until full retirement age to take SS. I know about the 7-8% per year stuff. But what about taking SS just a month or two prior to FRA? Would I collect less than the annual 7-8% divided by 12 if I took it a month early? Is the actual amount simply calculated on a monthly basis? The reason I'm asking has to do with taxes and calendar year planning. My FRA is 66 and 4 months, if that makes any difference.
