Dear Liz: When I turned 66, I applied for and then suspended my Social Security benefits so that my husband could take spousal benefits based on my work record. Shortly after he turned 69, he decided to start taking his full benefit from his own work record, so we canceled the spousal benefits.

After he applied to take his full benefit, I applied for spousal benefits from his account. Since I am only 67, the plan was for me to collect spousal benefits until I reached 70 and then collect off my account. Since I am the primary breadwinner, that allows the maximum lifetime funding should something happen to either of us. I sat with an employee at the local Social Security office. Together we processed all the appropriate documentation and she submitted it.

I just received a notice of denial that says, “We cannot approve your request because we received it after the 12-month limit.” I took the letter to the Social Security office for an explanation, and the woman had never heard of the rule it cited. The rule, it turns out, was designed to prevent people from repaying all the benefits they’ve received over the years so that they can restart their benefit at age 70. The rule says that they can pay back only benefits received in the prior 12 months to restart their benefits. But that is not what I did.

Answer: No, it’s not, but what you tried to do still won’t work.

Here’s the simplest way to explain it: There’s only one spousal benefit for each couple. Once you filed for your own benefit, allowing your husband to claim spousal benefits, you aren’t allowed to switch even though you hadn’t started receiving checks yet.

If it’s any consolation, you chose the right spouse to receive spousal benefits, since you’re the higher earner. It would have been best if your husband had waited to switch at age 70, when his benefit reached its maximum, but his checks are still substantially larger than they would have been if he had started earlier.

Another point that should be made because it’s often misunderstood, is that your husband was allowed to switch from spousal benefits to his own benefit because he started Social Security at or after his own full retirement age. If he’d started benefits before his full retirement age, which is currently 66, he would have been stuck with a discounted spousal benefit and couldn’t have switched to his own benefit later.
