Two individual Supplemental Security Income checks of $994 apiece add up to $1,988 a month. A married couple drawing the same benefit together receives $1,491, a shortfall of $497 a month, or roughly $5,964 a year, simply for being spouses rather than two unrelated recipients sharing a home. That gap traces to a formula that has applied since the program’s earliest years: the couple’s federal benefit rate is fixed at exactly 1.5 times the individual rate, never double it. The 2.8 percent cost-of-living adjustment that took effect for 2026 raised both numbers proportionally, leaving the underlying gap between marriage and cohabitation fully intact.
The 1.5-times formula behind the $1,491 figure
The Federal Register notice SSA filed on October 31, 2025 details exactly how the 2.8 percent adjustment produced this year’s figures. The unrounded annual federal payment for an individual rose from $11,604.53 to $11,929.46, which SSA then rounds down to the next lower multiple of $12 before dividing by 12 to reach the $994 monthly rate published in the agency’s 2026 fact sheet. The identical calculation for a couple starts at an unrounded $17,892.21, rounds down to $17,892, and divides into $1,491 a month, split into two equal checks of $745.50 paid separately to each spouse.
That couple figure works out to exactly 1.5 times the individual rate, not the 2.0 multiplier that two separate SSI checks would produce. The same fraction anchors an unrelated program: Title VIII of the Social Security Act pays certain World War II veterans living outside the United States 75 percent of the individual SSI rate, which the same notice sets at $745.50 for 2026, precisely half of what a couple’s combined benefit delivers. Both figures move in lockstep with the individual rate every time SSA issues a cost-of-living adjustment, so the 2.8 percent increase preserved the same proportional gap it inherited from 2025, when the couple rate was $1,450 against $967 for an individual.

Why an unmarried pair keeps more than a married one
SSA’s own research office has examined this gap and found it is not incidental. A 2003 policy paper by agency analysts Richard Balkus and Susan Wilschke, still posted on SSA’s site with a certification date in 2026, states plainly that a married couple who both receive SSI collect 25 percent less than they would if they lived together without marrying. The paper attributes the reduced couple rate to an economies-of-scale rationale: two people sharing one household are assumed to spend less than two people maintaining separate homes, so SSA pays the pair less than double.
The same logic does not extend to unrelated recipients who live together without marrying. Two adults who share a household but are not married, and who are not found to be presenting themselves to the community as husband and wife, are each guaranteed the full individual rate rather than the reduced couple rate. SSA’s analysts calculated that this produces a stark reversal: a married couple receiving SSI has a 45.1 percent poverty rate, compared with 9.8 percent for two unmarried SSI recipients sharing a home, according to the same research using Survey of Income and Program Participation data matched to agency records.
Everyday exclusions compound the difference. A married couple is entitled to only one $20 general income exclusion and one $65 earned-income exclusion between them each month, even when both spouses have income of their own. Two unmarried recipients living in the same household each claim a separate $20 and $65 exclusion, a combined advantage of $85 a month that has nothing to do with the couple’s core benefit rate and everything to do with how SSA defines a household once two people marry.
The same 1.5 multiplier reaches into households where only one spouse receives SSI. When an eligible individual marries someone who does not draw the benefit, SSA “deems” a portion of that spouse’s outside income into the couple’s combined countable income before calculating the payment. SSA’s analysts modeled this with an ineligible spouse earning enough outside income to trigger deeming: the recipient’s own benefit fell well below what an unmarried recipient with an identical live-in partner and identical outside income would keep, because a partner’s earnings are irrelevant to an unmarried recipient’s SSI calculation. The rule never applies to two adults who live together without marrying or being found to hold themselves out as husband and wife.
The poverty gap and the incentive it creates
SSA’s analysts warned that a benefit structure rewarding unmarried cohabitation over marriage creates its own enforcement problem. Because two people who report themselves as unmarried can each collect the higher individual rate, the agency’s research flagged an estimated $26 million in overpayments in fiscal year 2000 tied specifically to recipients misreporting their marital status, along with anecdotal accounts of advocates coaching clients to avoid appearing married to the community. The finding is nearly a quarter-century old, but the same 1.5 multiplier that created the incentive is the one still producing the $1,491 figure in 2026.
SSA’s paper laid out four options for closing the gap: eliminating the couple rate entirely and paying both spouses the individual amount, folding the couple discount into a broader reduction applied to any two adults who share a home, capping payments on a sliding scale for larger multi-recipient households, or restricting the couple rate to legally married pairs only. None of the four has been adopted. The agency estimated that eliminating the couple rate outright would have cost roughly $900 million a year in 2003 dollars for then-current beneficiaries alone, a price tag that has likely grown alongside the SSI rolls and the benefit rate itself.
SSA’s own analysts calculated that this ratio meant a married couple’s guaranteed income equaled 83 percent of the two-person poverty threshold in 2001, while two unmarried recipients receiving the same combined benefit reached 110 percent of it. The 2.8 percent adjustment that set the 2026 figures at $994 and $1,491 did not touch that structure. It simply carried the same 1.5-to-1 ratio, and the same $497 monthly gap, forward into another year of federal fact sheets.
