Yes, but there are some caveats. If you claim benefits before your full retirement age and continue to work, your income will be subject to the retirement earnings test, and your benefits could be reduced if your earnings exceed a certain limit.
However, once you reach full retirement age, your monthly benefit will be increased permanently to account for any months in which benefits were reduced. The retirement earnings test no longer applies after you attain your full retirement age and your benefit will not be reduced no matter how much you earn. Once you claim benefits, your benefits will be adjusted annually to reflect the increase, if any, in the cost of living.
