I’m 85 and my partner is 69, and we’re wondering if marriage makes sense from a Social Security standpoint

Finding love later in life is a wonderful thing, but many couples who meet in their senior years opt against legal marriage. Whether they have already navigated previous marriages or simply see no need for a certificate, the decision often comes down to more than romance. In this Reddit post, a couple aged 69 and 85 are weighing whether tying the knot makes sense from a Social Security perspective. Since both have been collecting benefits for years, they want to know if there is a genuine financial upside to marriage in 2026.

Marriage is primarily an emotional commitment, but it carries significant weight when it comes to federal benefits. The 2026 taxable earnings base stands at $184,500, and a 2.8% cost-of-living adjustment took effect in January, raising the dollar amounts in play compared to prior years. Analysts from AARP and the Senior Citizens League are currently projecting a 2027 COLA in the range of 3.5% to 3.6%, with the Social Security Administration scheduled to announce the official figure on October 14, 2026.

How getting married later in life can impact your Social Security benefits

Marriage unlocks two primary types of Social Security benefits: spousal and survivor. Spousal benefits cap at 50% of the primary earner’s benefit at full retirement age (FRA), while survivor benefits can reach 100% of the deceased spouse’s monthly check. The Social Security Administration sets the maximum benefit for someone claiming at FRA in 2026 at $4,152 per month, reflecting the 2.8% COLA applied at the start of the year.

A concrete example helps illustrate what is at stake. If the 85-year-old is a high earner receiving $4,152 a month and the 69-year-old receives $1,400, marriage could boost the lower earner’s check to $2,076 per month through the spousal benefit. If the older spouse passes away first, the survivor benefit would rise to the full $4,152. One important nuance: the spousal benefit is calculated on 50% of the higher earner’s FRA benefit, not their age-70 benefit, so delayed retirement credits do not increase what a spouse receives.

Couples with complex marital histories should also understand the remarriage rule. Under current SSA rules, a widow or widower who remarries at age 60 or later keeps eligibility for survivor benefits from a previous deceased spouse. Both partners in this couple are well past that threshold, so any prior survivor benefit rights would remain intact after a new marriage.

Social Security pays the higher of the two applicable benefit amounts, never both at once. Eligibility for spousal benefits also requires that the higher earner already be receiving their own benefits, which is satisfied here since both partners have been collecting for years.

Be careful when getting married for financial reasons

A boost in monthly checks can be tempting, but couples must account for the Medicare marriage penalty. Higher combined incomes can trigger the Income Related Monthly Adjustment Amount (IRMAA), which increases Medicare Part B and Part D premiums. In 2026, the IRMAA surcharge kicks in for joint filers with modified adjusted gross income above $218,000, based on their 2024 tax returns. Critically, IRMAA functions as a cliff: crossing a threshold by even one dollar triggers the full surcharge for both spouses for the entire year, not just the excess amount. The standard Part B premium is $202.90 per month in 2026, and the first IRMAA tier pushes that to $284.10 per month per person. Because IRMAA applies to each Medicare-enrolled spouse individually, a newly married couple where both cross the threshold could each face the surcharge, doubling the household cost.

Tax exposure on benefits is another factor worth modeling carefully. Up to 85% of Social Security income can become taxable once combined income crosses certain thresholds, and required minimum distributions from retirement accounts can push a couple deeper into that zone after marriage. One piece of recent tax law may offer some relief. The One Big Beautiful Bill Act, signed into law on July 4, 2025 (Public Law 119-21), includes a $6,000 senior bonus deduction for taxpayers aged 65 and older, effective for tax years 2025 through 2028. The deduction is available whether a filer itemizes or takes the standard deduction. For a married couple where both spouses are 65 or older, the deduction totals $12,000. The benefit begins to phase out for joint filers with modified adjusted gross income above $150,000 and disappears entirely at $250,000, so couples in the upper-middle income range will likely see only a partial benefit.

Ultimately, the financial benefits of marriage should serve as a secondary consideration rather than the primary driver. Late-life marriage calls for a full review of the couple’s entire financial picture, including RMDs, investment income, and the IRMAA exposure that comes with filing jointly. A fee-only financial planner or Social Security claiming specialist can run the numbers against both partners’ specific benefit records and income sources before any decisions are made.

Editor’s note: This pass adds the projected 2027 COLA range of 3.5% to 3.6% and the October 14 official announcement date, enhances the IRMAA section with the cliff-system detail that crossing any income threshold by even one dollar triggers the full surcharge for both spouses, and clarifies that the One Big Beautiful Bill Act senior deduction phases out completely at $250,000 MAGI for joint filers rather than simply beginning to phase out at $150,000.
