Dear Liz: I was told by a staff person at our Social Security office that because I am seven years older than my husband (he is 58, I am 65), the “file and suspend” wouldn’t work for me and that because I am waiting until 70 to claim benefits, it was a non-issue.

Is that correct? How does the “lump sum” option figure into the equation? How quickly would I have to file and suspend not to be penalized for the process?

Answer: The “file and suspend” option allows you to file for your Social Security benefit and then immediately suspend that application.

The suspension means your benefit continues to earn delayed retirement credits that boost the amount of your checks 8% each year until age 70, when your benefit reaches its maximum. The file and suspend option is available only once you’ve reached your full retirement age (which is currently 66 but which is rising to 67 for those born in 1960 or later).

There are two main reasons to file and suspend. The first is to allow your spouse to claim spousal benefits based on your work record. The second is to give you the option to change your mind.

If you file and suspend, then discover you need the money, you can either start benefits at the larger amount you’ve earned with delayed retirement credits, or give up those credits and instead receive a lump sum payment of benefits back to the date you suspended your application.

There’s no reason for you to file and suspend for spousal benefits since your husband would have to be 62 before he could file for those checks. By that time, as the Social Security representative points out, you’ll be close to age 70, when you plan to start your benefit anyway.

You could still file and suspend as an insurance strategy — in case you need the money later. If that’s your plan, then doing so at your full retirement age of 66 would give you the option of requesting the largest possible lump sum if you do change your mind.

Decisions about when to start Social Security benefits and how to coordinate benefits when you’re married (or divorced, or widowed) can be extremely complex.
