Unmarried Couples and MSP: How Living Together Affects Your Income Count

If you and your partner are not legally married, the Medicare Savings Program generally counts only your own income and resources against the individual limit — not your partner's — even if you live together, share a household budget, or have lived together for decades. The higher 'couple' income limit applies only to legally married spouses.

MSP Only Recognizes Legal Marriage as a "Couple"

Medicare Savings Program rules — like the Medicaid and SSI rules they're built on — define eligibility around two categories: "individual" and "couple." Federal guidance uses "couple" to mean spouses, not any two adults sharing a home (Social Security Administration, POMS guidance on Medicare Savings Program income and resource limits). Unmarried partners, roommates, and adult children living with a Medicare beneficiary are treated as separate individuals for this purpose, no matter how long they've lived together or how their finances are actually intertwined day to day.

What This Means for Your Income Limit

If you're unmarried, your state Medicaid agency compares only your own countable income against the individual limit for each tier — currently $1,350/month for QMB, $1,616/month for SLMB, and $1,816/month for QI in 2026 (before your state's cost-of-living adjustments, if any). Your partner's Social Security, pension, or wages generally aren't added in, and their resources generally aren't counted toward your asset test either. This can work in your favor: a couple living together where one partner has little income and few assets may still qualify even if the other partner earns considerably more — something that wouldn't be possible if they were legally married and evaluated under the couple limit.

What About Shared Expenses or a Partner's Assets?

Sharing rent, utilities, or groceries with an unmarried partner doesn't turn their money into your income. The same generally goes for resources: a bank account, car, or investment held solely in your partner's name isn't counted as yours. Where it gets more complicated is jointly titled accounts or property — if your name is on an account or asset alongside your partner's, a caseworker may count some or all of it as a resource available to you, depending on your state's rules and how the account is structured. If you jointly own significant assets with a partner, it's worth asking your state Medicaid agency how they'll be treated before you apply.

A Few Exceptions to Watch For

A handful of states still recognize common-law marriage, and if yours does and you meet its specific requirements, your state may treat you as legally married even without a marriage certificate — which would bring you back under the couple limit. Some caseworkers also ask whether you're "holding yourselves out as married" (for example, filing joint tax returns or using a shared last name), which can affect how your application is evaluated in certain states. Because these rules vary, confirm your specific situation with your state Medicaid agency or a free SHIP counselor rather than assuming either outcome.

If you are legally married, the math works differently — see our guide to how married couples' income is counted for MSP for the couple-limit rules.
