Dear Liz: I never expected to be where I am financially. I work as an independent piano teacher and my present earnings are just enough to get by (which isn’t saying much in Southern California). I was married for 18 years and am now single, with no plans to remarry.

After I turn 66 next year, I intend to apply for Social Security benefits as a divorced spouse because my personal Social Security benefits would amount to just $875 a month and my ex is doing quite well (with earnings somewhere in the six-figure range). I anticipate the divorced spousal benefit will be greater than my own.

But I have a lot of questions. Will waiting until my former husband is 66 or 70 (he is 64) do anything to maximize my benefits? Will my Social Security be taxable? How much am I allowed to continue earning if I also receive Social Security?

Answer: Spousal and divorced spousal benefits can help lower earners get larger Social Security checks. Instead of just receiving their own retirement benefit, they can receive up to half of the higher earners’ benefits. But divorced spousal benefits are different in some important ways from the spousal benefits available to married people.

If you were still married, your benefit would be based on what your husband was actually getting. If he started benefits early, that would reduce the spousal benefit you could get. You also couldn’t get a spousal benefit unless he was already receiving his own.

Divorced spousal benefits are available if your marriage lasted at least 10 years and you aren’t currently married. If you meet those qualifications, you can apply for divorced spousal benefits as long as both you and your ex are at least 62 — he doesn’t need to have started his own benefit. Your divorced spousal benefit will be based on his “primary benefit amount,” or the benefit that would be available to him at his full retirement age (which is 66 years and two months, if he was born in 1955). It doesn’t matter if he starts early or late; that doesn’t affect what you as his ex would receive.

Spousal and divorced spousal benefits don’t receive delayed retirement credits, so there’s no advantage for you to delay beyond your own full retirement age (which is 66, if you were born in 1954) to start. Your benefit would have been reduced if you’d started early, though, so you were smart to wait.

Also, waiting until your full retirement age means you won’t be subjected to the earnings test that otherwise would reduce your checks by $1 for every $2 you earn over a certain amount ($17,640 in 2019).
