Continuing to work past retirement age can give you more flexibility about when to start claiming your social security benefits. Seniors who wait to receive social security after 66 years of age receive 100 percent of PIA (primary insurance amount). By waiting until age 70, they'll receive 132 percent of the PIA. There is no point in waiting beyond age 70 because that’s when credits stop accruing. Note that it is important to keep an eye on the taxation of social security in your non retirement years.
