I am eligible for social security soon. I will be 62 and my wife is 56. She will continue to work after I retire. I plan on working part time (up to $15K/year) Do my wife's earnings have any impact on my social security?

Jeff,
No, your wife's earnings have no effect on your Social Security retirement benefit. However, if you earn more than the exempt amount, currently $15,720, your benefit will be reduced.
Best.
