Most Couples Overlook the Social Security Spousal Rule Worth Up to 50% of a Partner’s Benefit

Social Security anchors the retirement income of tens of millions of Americans, but the program’s spousal benefit remains one of its least understood provisions. Many married and divorced retirees quietly leave money on the table simply because they never learned a second path to benefits exists.

How Social Security spousal benefits work

The standard route to Social Security retirement benefits requires 40 work credits earned over a lifetime. In 2026, one credit equals $1,890 in earnings, and you can earn a maximum of four credits per year. To collect all four credits in a single year, a worker needs at least $7,560 in covered earnings. The threshold rises each year in step with average wages.

But the 40-credit requirement applies only to your own earnings record. Social Security spousal benefits allow a spouse to receive monthly benefits based on a partner’s earnings record rather than their own. That means someone who spent years outside the paid workforce, caring for children or a household, may still qualify for a meaningful monthly check in retirement.

The maximum spousal benefit available at Full Retirement Age is 50% of the worker’s Primary Insurance Amount, which is the benefit the worker would receive at their own Full Retirement Age. Note that this is 50% of the worker’s FRA benefit, not 50% of whatever the worker actually receives if they claimed early or late. So if your spouse’s FRA benefit is $2,500 a month, your maximum spousal benefit is $1,250.

Full retirement age is 67 for anyone born in 1960 or later. Claiming spousal Social Security benefits before reaching full retirement age permanently reduces those monthly payments. Claiming spousal benefits at 62 reduces them by 35%. That reduction is permanent and applies for life, so the timing of your claim carries real long-term consequences.

On the flip side, waiting past FRA brings no reward. When you claim Social Security based on your own earnings record, delaying your filing past full retirement age boosts your monthly checks by 8% for each year you wait, until age 70. But those delayed retirement credits do not apply to spousal Social Security benefits. Once you reach your FRA, filing right away is the right move for a spousal benefit.

Key rules to keep in mind

The mechanics of claiming spousal benefits differ depending on whether you are currently married or divorced. A few rules apply broadly:

• If you’re married, you cannot claim spousal benefits until your spouse has filed for their own Social Security.
• If you’re divorced, a divorced spouse may still qualify if the divorce has been final for at least two years and both spouses are age 62 or older, even if your ex has not yet claimed their own benefit.
• Claiming spousal benefits on an ex’s record does not affect what the ex or their current spouse receives.
• An ex-spouse cannot block or deny your spousal benefit claim. The ex-spouse is not even notified when a claim is made.
• Claiming before your own FRA permanently reduces the spousal benefit.
• There are no delayed retirement credits for waiting past FRA on a spousal benefit claim.

The divorce rules carry their own requirements

Divorced spouses face one additional hurdle that the article on married spousal benefits often glosses over: the 10-year marriage rule. A divorced spouse benefit allows eligible divorced individuals who were married for over 10 years to receive Social Security benefits based on an ex-spouse’s earnings record instead of their own. The rule is strict: if your marriage lasted 9 years and 364 days, you do not qualify. The clock runs from the legal wedding date to the date the final divorce decree was entered, not from separation or from when papers were filed.

If you were married more than once and each marriage lasted at least 10 years, you can claim on whichever ex-spouse’s record produces the higher benefit. And if an ex-spouse has died, the math shifts further in your favor: an eligible surviving divorced spouse who was married for over 10 years may receive up to 100% of the deceased ex-spouse’s benefit amount, depending on claiming age and eligibility.

Know what you’re entitled to before you file

Spousal benefits serve as a critical income floor for people who lack enough work history to qualify for Social Security on their own. Even retirees with their own earned benefit can benefit from understanding the spousal rules: if your own benefit is smaller than 50% of your spouse’s FRA amount, Social Security will top it up to that higher level automatically.

The stakes are high enough that it pays to review your situation carefully well before you plan to file. A mistimed claim, such as filing early to get payments started sooner, can lock in a permanently reduced monthly benefit for life. Understanding both the married and divorced-spouse rules, including the 10-year marriage threshold and the two-year waiting period for divorced claimants, can make a meaningful difference in your total lifetime income from the program.

Editor’s note: This update added the 10-year marriage requirement for divorced-spouse eligibility, the two-year post-divorce waiting period for independent claims, the specific 35% reduction for claiming spousal benefits at age 62 with a full retirement age of 67, and the clarification that the 50% spousal benefit is calculated from the worker’s FRA benefit rather than from the amount the worker actually receives.
