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.

Dear Liz: You’ve been writing about the “file and suspend” option that allows you to delay taking Social Security while still reserving the ability to get a lump sum if you later change your mind.

If I file and suspend but choose not to take a lump sum before my benefit maxes out at 70, what happens to those funds? What happens to those funds if I die before 70?

Answer: Remember that Social Security is a pay-as-you-go program. The Social Security taxes you pay aren’t piled up in some kind of account, waiting for you to retire. Your taxes pay current retirees’ benefits, just as future workers’ taxes will pay yours.

When you delay starting Social Security, you’re rewarded with a potentially larger check each year you put off claiming until age 70. Your benefit grows by about 7% each year between age 62 and your full retirement age, which is currently 66.

Between full retirement age and 70, your benefit grows at 8% each year in what’s called “delayed retirement credits.”

If you file and suspend at your full retirement age, then change your mind, you can get a lump sum equal to all those checks you passed up since you filed. However, you lose the 8% delayed retirement credits you could have otherwise claimed.

Your benefit is reset to the lower amount you would have received at full retirement age, and that’s the benefit on which all future cost-of-living calculations would be made.

Should you die after filing and suspending, your surviving spouse would be able to benefit from those delayed retirement credits. His survivor’s benefit would be equal to what you could have claimed as of the date of your death.
