Dear Liz: I am 64 and still working and earning decent pay. My wife is 61 and retired. I have been a high earner for most of my life while she was working and raising our family. I don’t plan to retire anytime soon. Is it a good idea for her to start taking Social Security at 62?

Answer: The vast majority of people are better off delaying their Social Security applications for as long as possible so they can maximize their lifetime benefits. It’s especially important for you to delay, since as the higher earner, your benefit will determine what the survivor gets.

Your wife, however, may be one of the few who is better off starting early. That may be the case if you continue to delay your application, and her eventual spousal benefit is more than what she would receive on her own record.

If both of those things are true, she could start her own reduced retirement benefit at 62, then switch to a spousal benefit of up to half of your check after you apply for your benefits — preferably at age 70, when they max out.

Your wife won’t be able to get a spousal benefit until you apply for your own. On the other hand, she won’t be allowed to switch benefits if you’re already receiving yours when she applies.

Clearly, there are a lot of rules involved, and the best course for you two will depend on the specifics of your situation. You’d be smart to use a Social Security claiming site, such as Maximize My Social Security or Social Security Solutions, to help you determine your best approach.

Dear Liz: You recently wrote that someone’s Social Security survivor benefit would be the same as her spouse’s, including the 8% annual delayed retirement credits and cost of living increases. My husband just took his Social Security at age 70 but we were told I wouldn’t get his full survivor benefit as I took my own benefit at age 62. Is it because in the other question, the wife took her benefit at her full retirement age of 66 years and 8 months? So confused with all the rules!

Answer: The rules are certainly confusing, but the advice you got was wrong.

Your early start certainly reduced your own retirement benefit, but doesn’t reduce your survivor benefit. If your husband dies first and has the larger benefit, you’ll get a survivor benefit equal to his check and your retirement benefit will cease.

What does reduce survivor benefits is starting them early. Survivor benefits can start as early as 60, but you don’t get the full amount until you’ve reached full retirement age. (Full retirement age was 66 if you were born from 1943 to 1954. Between 1955 and 1959, full retirement age increases by two months each year; for people born in 1960 and later, full retirement age is 67.)

If you’re already past your full retirement age, you don’t need to worry about a reduced survivor benefit. If your husband dies before you reach full retirement age, the correct claiming strategy depends on your situation. Consider getting expert advice about when to switch to the survivor benefit.

Dear Liz: I am trying to understand the Social Security survivor benefit. I delayed starting to receive my benefits until I reached age 70. My wife just started receiving benefits at 66 and 10 months. Upon my passing, will she receive my benefit at full retirement age, plus the 8% annual delayed retirement credit plus the annual cost of living increases?

Answer: Assuming your benefit is larger than hers, then yes — her survivor benefit would be the amount you were getting at your death. The survivor gets the larger of the two checks a couple was receiving, and the other benefit goes away.

Dear Liz: My husband turned 70 this past May and waited until then to take his Social Security. I am 61 and will qualify for a benefit based on my work history, although my benefit is substantially less than his. I understand I can take half of his benefit at my full retirement age of 67. I asked a Social Security representative if I could take my (reduced) benefit at age 62 and then switch to half of my husband’s benefit at 67. She told me I should file at 62 and take half of his benefit at that time. That sounds too good to be true, and your article and others I’ve read disagree with her advice.

Answer: Social Security representatives aren’t supposed to give people advice about when or how to claim their benefits. But ideally they would offer correct information about your options.

Congress did away with most people’s ability to switch from a spousal benefit, which is up to 50% of their partner’s amount, to their own benefit. Now when you apply for Social Security, you’ll be considered to be applying for both a spousal benefit and your own benefit and you’ll get the larger of the two. There’s no switching later.

It could be that your own benefit will always be smaller than your spousal benefit, regardless of when you apply. But that doesn’t mean it’s a smart decision to lock in a permanently reduced benefit by applying early.

Dear Liz: My dad recently passed away. He was technically married, however his wife kicked him out of their home three years prior to his passing, making him homeless. Is she eligible to receive Social Security survivor benefits?

Answer: Social Security doesn’t try to gauge how married a couple was. As long as they were legally wed, she could be eligible for a survivor benefit.
