Spousal Social Security Benefits: A Little-Known Rule That Can Boost Retirement Income

Married and divorced individuals can claim spousal benefits worth up to half of their partner's full retirement age benefit without needing any work credits. These benefits do not increase if claimed after full retirement age, so filing at that point is recommended. Even those with their own benefit may receive the spousal amount if it is higher than their personal entitlement.
The spousal benefit calculation hinges on the primary earner's full retirement age amount, not their actual claimed benefit. For 2026, one work credit requires $1,890 in earnings, with a maximum of four credits earned annually. Divorced claimants enjoy notable flexibility: they may file on an ex-spouse's record before that person retires, and the ex cannot block the claim. Importantly, a divorced person's spousal claim does not reduce benefits available to the ex's current spouse.
Timing matters differently here than for personal benefits. While delaying one's own claim past FRA earns an 8% annual increase until age 70, spousal benefits accrue no such delayed retirement credits. Filing before FRA triggers permanent reductions, so reaching full retirement age signals the optimal moment to apply for spousal benefits.
This rule could meaningfully affect retirement security for non-working spouses, particularly older women who left the workforce for caregiving roles, and divorced individuals with limited earnings histories. Since spousal benefits require no work credits, they may serve as a financial safety net for households where one partner did most of the earning. However, the lack of delayed retirement credits means beneficiaries who wait past FRA may inadvertently forfeit income, suggesting that awareness of filing timing could be as valuable as the benefit itself.
