Money Magazine article provides several strategies married couples should consider.

If there’s one set of rules worth understanding, it’s spousal benefits. Every year, couples leave literally billions of dollars on the table because they make the wrong claiming choices. Here are three secrets to getting this claim right, and how they apply to your situation:

1. To get spousal benefits, the primary earner must file for retirement benefits first. Spousal benefits can equal as much as half of the amount the person would receive in individual Social Security benefits at full retirement age (FRA). For anyone born in 1943 through 1954, FRA is 66; it will gradually rise to 67 for people born in 1960 or later.

2. If you file for a spousal benefit before your FRA, you will end up with a smaller amount. You can file as early as age 62 but if you do, you will be hit with benefit reductions. Retirement benefits will rise each month they are deferred between FRA and age 70. Spousal benefits peak at FRA, so there is no reason to defer claiming them past that point.

3. Use a file-and-suspend strategy. If both spouses defer claiming until FRA, the higher-earning spouse can file and suspend benefits then. This way, the lower-earning spouse can file for spousal benefits, allowing his or her individual retirement benefit to grow due to delayed retirement credits. Then you can each file for maximum retirement benefits at age 70.
