My FRA is January 2017; my wife's FRA is February 2017. My benefit is about 6 times as large as my wife's benefit. She is not working and will not work in the future. I will work until 2021. Is there an obvious strategy, given the closing of the file and suspend "loophole"?
My best guess would be for your wife to file on her record now, and for you to file a restricted application for spousal benefits only. You could then switch to your own record at age 70, and your wife could file for an excess spousal benefit on your record. You may want to run the maximization software available on this website, though, in order to eliminate the guesswork.
