Will benefits still be recalculate and possibly increase as I am still working and am 72
Hi,
Yes, your Social Security retirement benefits can be recalculated to include higher earnings years regardless of your age at the time you have the earnings. In order for your benefit rate to increase, though, your earnings in a year would need to be higher than one of your previous 35 highest wage-indexed earnings years used to calculate your current benefit rate (https://www.ssa.gov/pubs/EN-05-10070.pdf).
Social Security automatically recalculates benefit rates for people who are already receiving benefits and who have additional earnings which are high enough to raise their benefit amount, so you don't need to do anything to get any benefit increases for which you may be eligible. However, you can sometimes speed up the process by submitting proof of your most recent year of earnings (e.g. W-2 forms, tax returns) and requesting a manual recomputation.
Best, Jerry
