There used to be a nice loophole called “file-and-suspend” that let a spouse collect the 50% spousal distribution while the higher wage earner waited.

In researching this post, I found that the recent budget deal closed that loophole (still open until 6 months after Bill was signed in December-ish)

Between now and six months after the bill is enacted, file-and-suspend is still in effect, she said. Plus, it will still be possible to file for a spousal benefit based on a spouse’s suspended benefit. And, individuals who will be over 62 as of Dec. 31, 2015 can still plan on filing a restricted application for spousal benefits when they turn FRA over the next four years.
Article does have some thoughts worth reading if you are near that age.
