First, the file-and-suspend strategy will no longer work after May 1, 2016. At that time, a person must file for Social Security and actually receive benefits in order for a husband or wife to get a spousal benefit.
However, for those who are at least 66 or who will turn 66 by April 30, 2016, there is still an opportunity to get in under the old file-and-suspend system. Those who do squeak in under the deadline will be grandfathered in under the old file-and-suspend rules.
Second, another change will eliminate "restricted applications," a mechanism that allows persons who are between full retirement age and age 70 to file an application to claim spousal benefits but defer collecting their own benefits; upon reaching 70, they change from receiving spousal benefits to receiving their own (larger) benefits.
With the elimination of restricted applications and the introduction of deemed filing for all ages, a spouse can only receive the larger of either their spousal benefit or their own benefit. They can't change their choice either, which means no deferring benefits until age 70 and then switching options for a larger monthly check.
Last, this change affects suspended benefits, a mechanism that allows persons to file for Social Security but suspend their benefits, then at a later date request payments dating retroactive to their original filing date.
Under the new rules, Social Security beneficiaries can no longer retroactively unsuspend benefits.
There is no lumpsum benefit offered.
