Q&A: Social Security benefits for children

Dear Liz: My husband was 51 when our last child was born, meaning that our son was only 15 when my husband turned 66. Because I was working full time and we had sufficient income, we adhered to the traditional advice of delaying my husband’s Social Security payment. However, when he filed this past year at age 69, we learned that our son is eligible to receive a considerable monthly amount. Fortunately, the Social Security office was able to backdate my husband’s application for six months, but nevertheless we lost out on several thousand dollars by not filing when my husband was 66. Although his monthly payout would have been lower, the accumulated difference would have been considerable with our son’s payment. Therefore, although most retiring people do not have minor children, I believe that all financial advisors should be aware of this option and that those parents should plan carefully to maximize their payout.

Answer: More than 4 million children receive Social Security benefits because their parents are disabled or deceased or have reached retirement age. A child can receive up to half the parent’s disability or retirement check. If the parent dies, a child’s survivor benefit can be up to 75% of the parent’s basic benefit. (There’s a limit to how much a family can receive, though, which ranges from 150% to 180% of the parent’s check.) Benefits typically stop at age 18, although they can continue until two months past the child’s 19th birthday if the child is still in high school. Benefits can continue indefinitely if the child is disabled.

Children’s benefits can be subject to the same earnings test that reduces Social Security retirement checks if the parent claims early and continues working. So it often makes sense to wait to start benefits until the parent is full retirement age, currently 66, when the earnings test no longer applies. You’re right that delaying beyond that age may not make sense when the child is young enough to receive benefits, since they can considerably boost a family’s total benefit.

Having minor children at retirement age definitely complicates the calculation of when to take benefits. Many free Social Security claiming calculators don’t let you include minor children in your calculation, so if you’re in this situation it can be worth paying $40 to get a customized claiming strategy from calculators such as MaximizeMySocialSecurity.com.
