Dear Liz: I will be 66 in May 2016. My wife is 68 and retired. She began receiving Social Security when she turned 66. I am still working, making a high six-figure income, and will continue to do so until I reach 70, when my Social Security benefit reaches its maximum. I plan to use my Social Security earnings to save for my grandchildren’s college educations (unless an emergency occurs and we need the income). I want to maximize the amount that I can give them. What is the best strategy, taking into consideration the recent change in Social Security rules relating to “claim now, claim more later”?

Answer: You just missed the April 29 cutoff for being able to “file and suspend.” Before the rules changed, you could have filed your application at full retirement age (66) and immediately suspended it. That would allow your benefit to continue growing while giving you the option to change your mind and get a lump-sum payout dating back to your application date.

Since Congress did away with file-and-suspend for people who turn 66 after April 30, that option is off the table for you. There are other ways to maximize your household benefit, said economist Laurence Kotlikoff, author of “Get What’s Yours: The Secrets to Maxing Out Your Social Security.” They include:

•Your wife suspends her benefit and lets it grow for another two years, then restarts getting checks when she turns 70.

•At 66, you file for a spousal benefit. People who are 62 or older by the end of this year retain the ability to file a “restricted application” for spousal benefits only once they turn 66. That option is not available to younger people, who will be given the larger of their spousal benefits or their own benefits when they apply.

•At 70, you switch to your own, maxed-out benefit. Again, the ability to switch from spousal to one’s own benefit is going away, but you still have the option to do this.

Consider saving in a 529 college savings plan, which offers tax advantages while allowing you to retain control of the money. You can even withdraw the money for your own use if necessary, although you would pay income taxes and a 10% federal penalty on any earnings.

You should know, however, that college-savings plans owned by grandparents can mess with financial aid. Plans owned by grandparents aren’t factored into initial financial aid calculations, but any disbursements are counted as income that can negatively affect future awards. One workaround is to wait until Jan. 1 of the child’s junior year, when financial aid forms will no longer be a consideration, and pay for all qualified education expenses from that point on.

Obviously, you won’t have to worry about this if your grandchildren wouldn’t qualify for financial aid anyway. If your children also make six-figure incomes, that’s likely to be the case.
