If both partners can wait until age 70 to file, they’ll both benefit from delayed retirement credits, which increase benefits by 8 percent a year between full retirement age and age 70. (Full retirement age is 66 for those who were born between 1943 and 1954; it gradually increases to 67 for those born in 1960 or later.)
In instances in which one spouse is the higher earner, it makes sense for that spouse to postpone benefits as long as possible. Consider having the lower-earning spouse file for benefits at full retirement age, or even as early as 62 if necessary. Use the lower-earning spouse’s benefits, along with income from other sources, to pay expenses while the higher earner’s benefits—which will get the biggest boost from delayed retirement credits—continue to grow until the higher earner turns 70.
However, if you claim survivor benefits at age 60, you’ll be entitled to only about 71.5 percent of your late spouse’s benefits, compared with 100 percent of your late spouse’s benefits if you wait until you reach full retirement age. If your own benefits will be less than the survivor benefits, a better strategy is to file for your own benefits at age 62 and switch to survivor benefits when you reach full retirement age, which is when those benefits reach their maximum.
Conversely, if your own benefit will be larger, you could claim survivor benefits as early as age 60 and allow your own benefits—which are eligible for delayed credits—to grow until you reach age 70, at which point you could switch to your own benefits. Survivor benefits don’t increase after you reach your own full retirement age, so this is the most effective way to take advantage of delayed-retirement credits.
Whether you qualify to receive these benefits depends on the amount of your own retirement benefit (if any) and the amount of the ex-spousal benefit at the time you file. Spousal (and ex-spousal) benefits are a maximum of 50 percent of the spouse’s full benefit—that is, the amount available at full retirement age.
If you’ve been divorced for at least two years, you don’t need to wait until your ex has started to collect retirement benefits, and you don’t have to notify them that you’re collecting spousal benefits based on their record.
Filing for ex-spousal benefits won’t affect the amount of benefits your ex is eligible to receive, nor will it affect the amount of benefits your ex’s current spouse will receive if your ex remarried. If you’ve been married more than once and meet the other eligibility criteria, you can choose which ex-spouse’s earnings record to use.
If your ex dies, you may also qualify for survivor benefits, which are even more valuable. In that case, you’re eligible to claim as much as the entire amount of your late ex’s benefits.
