If an individual was born on or before 5/1/1950 and they suspended their retirement benefit on or before the 4/29/2016 deadline to do so under the old rules, others can receive auxiliary benefits based on their record while their retirement benefit is suspended and they can receive auxiliary benefits on others' records while their retirement benefit is suspended.
Individuals born on or after 1/2/1954 can never file a restricted application for only one benefit, e.g. for just their spousal benefit. They will instead be deemed to have also filed for other available benefits, e.g. their retirement benefit. If their retirement benefit is larger, they will receive it rather than the smaller spousal benefit. If they file for and suspend their retirement benefit, they also would not be able to receive auxiliary benefits based on another's record while their retirement benefit is suspended.
No one can collect auxiliary benefits, e.g. spousal or child benefit, based on the record of someone whose retirement benefit was suspended after 4/29/2016 while their retirement benefit is suspended. Only those born on or before 5/1/1950 were able to suspend their benefit before this deadline.
No one who suspends their retirement benefit after 4/29/2016 can collect an excess spousal or excess widow(er)'s benefit while their retirement benefit is suspended.
Only those who suspended their retirement benefit on or before 4/29/2016 can receive a lump sum payment of previously suspended benefits. Those who suspend their retirement benefits after 4/29/2016 can no longer receive their suspended retirement benefits in a lump sum payment.
Those who are subject to deeming, but who aren't deemed to be filing for their excess spousal benefits when they file for their retirement benefit because their spouse has not yet filed for their retirement benefit, will be so deemed as of the date their spouse files for their retirement benefit.
