Thank you for your question about working while collecting Social Security benefits. If you decide to go back to work at age 68, it will not affect your Social Security benefit amount. Starting with the month you reach full retirement age, which is 66 for you, there is no limit on how much you can earn and still receive your benefits.
The Earnings Test, which is the maximum amount you can earn before benefits are withheld, only applies to a person taking a Social Security benefit before full retirement age, and having earned income at the same time.
If your wife is receiving a benefit based on her own work record, it will not affect her benefit if you return to work. If her benefit is based on yours (a spousal benefit), it will also not be affected by the Earnings Test because you are over full retirement age. The nature of your wife’s pension, however, could affect her own benefit or her spousal benefit, if her pension is a non-covered pension (from a job where she didn’t pay Social Security taxes). But it will not affect your benefit.
