When a husband or wife moves into a nursing home, families brace for the financial questions almost as quickly as the medical ones. One of the most frightening is also one of the most misunderstood: if Medicaid pays for the care, does the spouse still living at home lose access to the couple's income?
The fear is understandable, because Medicaid does require the spouse in the nursing home to put most of their monthly income toward the cost of care. Yet federal law has built in a protection specifically so the at-home spouse is not left without enough to live on.
That protection is called the Minimum Monthly Maintenance Needs Allowance, often shortened to MMMNA or MMNA. It is the income counterpart to the resource protections we cover in our guide to the community spouse resource allowance.
Yes — the at-home spouse can keep part of the nursing-home spouse's income. Federal Medicaid law sets a Minimum Monthly Maintenance Needs Allowance (MMMNA) that guarantees the community spouse a baseline monthly income, and the institutionalized spouse's income is diverted home to fill any shortfall.
What Is the Monthly Maintenance Needs Allowance?
The MMMNA is the floor that federal Medicaid rules place under the income of the community spouse — the term for the husband or wife who remains in the community while their partner receives institutional care. It answers a single question: what is the least this spouse needs each month to keep their household running?
Medicaid law refers to the at-home partner as the community spouse and the partner in the facility as the institutionalized spouse. Keep in mind that the MMMNA protects only the community spouse, not the household as a single undivided unit.
If the community spouse's own income already sits above this floor, nothing changes and no income is shifted. If it falls below the floor, a portion of the institutionalized spouse's income is redirected to bring the community spouse up to the allowance.
The Minimum Monthly Maintenance Needs Allowance is the lowest monthly income federal law lets a community spouse keep when their partner is on Medicaid in a nursing home. It functions as an income floor: if the at-home spouse earns less, the institutionalized spouse's income is diverted to make up the gap.
How Is the Nursing-Home Spouse's Income Actually Shifted Home?
Once Medicaid approves the institutionalized spouse, that spouse must contribute almost all of their monthly income toward the nursing home bill. This contribution is often called the patient pay amount or share of cost.
Before that contribution is calculated, Medicaid carves out a few protected pieces. The institutionalized spouse keeps a small personal needs allowance for incidentals, and — critically — an amount can be set aside for the community spouse.
That set-aside is the Community Spouse Monthly Income Allowance, sometimes abbreviated CSMIA. It is the actual dollar figure transferred from the nursing-home spouse to the at-home spouse each month.
The math is straightforward in concept. The CSMIA equals the community spouse's MMMNA minus the community spouse's own gross monthly income.
Note that Medicaid generally follows the name on the check rule for the community spouse. Income paid solely in the community spouse's name is theirs to keep and is not counted toward the institutionalized spouse's eligibility.
The diverted amount is called the Community Spouse Monthly Income Allowance (CSMIA). It equals the spouse's MMMNA minus their own gross monthly income. If the at-home spouse's allowance is set at the MMMNA and their own income is lower, the institutionalized spouse transfers the difference home each month.
Does the Community Spouse's Own Income Affect Eligibility?
A frequent worry is that the at-home spouse's salary, pension, or Social Security will disqualify the couple. For the institutionalized spouse's Medicaid eligibility, the answer is generally no.
Medicaid evaluates the institutionalized spouse's eligibility largely on that spouse's own income, not on the couple's combined paychecks. The community spouse's income is set aside under the name on the check rule and does not count against the application.
This is a meaningful relief for families where the at-home spouse still works or has a solid pension. Their income protects them — it does not penalize the spouse who needs care.
The flip side is the one we have already described. Precisely because the community spouse keeps their own income, that income is what determines whether any of the institutionalized spouse's income gets diverted at all.
The Minimum and Maximum: How the Federal Figures Work in 2026
The MMMNA is not a single number. Federal law sets a minimum allowance and a separate maximum allowance, and a given spouse's figure falls somewhere between the two.
The minimum is tied to the federal poverty guidelines. It is calculated as 150% of the federal poverty level for a household of two, divided by twelve, and it is updated every July 1 when new poverty figures take effect.
The maximum is a flat federal cap that is updated every January 1. As published by the Centers for Medicare & Medicaid Services (CMS), the maximum stood at $3,948 per month for 2025.
The 2026 maximum adjusts upward from that figure, and the minimum changes again on July 1, 2026. Because both numbers move on different schedules, verify the exact current amounts against CMS or your state Medicaid agency before relying on them — do not assume last year's figure still applies.
Be aware that Alaska and Hawaii use higher minimums because their federal poverty guidelines are higher. A handful of states also set their own MMMNA at or near the federal maximum, so the figure that governs your case is ultimately the one your state publishes.
| Figure | What it is | How it updates |
|---|---|---|
| Minimum MMMNA | 150% of the federal poverty level for a household of two, divided by 12 | Each July 1, with new poverty guidelines |
| Maximum MMMNA | Flat federal cap on the community spouse income allowance | Each January 1 ($3,948/month for 2025; verify the 2026 figure) |
| CSMIA | The dollars actually diverted from the nursing-home spouse | Recalculated whenever income or the allowance changes |
The MMMNA has two federal bookends. The minimum equals 150% of the poverty level for a two-person household, updated each July 1; the maximum is a flat cap updated each January 1, published at $3,948 monthly for 2025. Confirm the 2026 figures with CMS, since each changes on its own schedule.
The Excess Shelter Allowance: How a Spouse Reaches the Maximum
Most community spouses do not automatically receive the maximum allowance. They start at the minimum and can climb higher only if their housing costs are high enough to justify it.
The mechanism is called the excess shelter allowance. Medicaid compares the community spouse's monthly shelter costs against a shelter standard equal to 30% of the minimum MMMNA.
Shelter costs include rent or mortgage payments, property taxes, homeowner's insurance, and a utility figure — either the actual utility cost or a standard utility allowance set by the state. Anything above the shelter standard is the excess.
That excess amount is added on top of the minimum MMMNA, raising the community spouse's allowance, but never above the federal maximum. This is why two community spouses with identical incomes can end up with very different allowances: the one with a larger mortgage and higher taxes may qualify for more.
Suppose a community spouse's allowance starts at the federal minimum and the shelter standard is 30% of that minimum. If their mortgage, taxes, insurance, and utilities exceed that 30% threshold, the overage is added to the minimum — pushing their allowance toward the maximum cap.
Because the floor and the cap change each year, run this calculation with the current-year figures rather than an old worksheet, and confirm your state's standard utility allowance, which varies.
The excess shelter allowance raises a community spouse's MMMNA above the minimum. Medicaid adds the amount by which monthly shelter costs — rent or mortgage, taxes, insurance, and utilities — exceed 30% of the minimum allowance, capped at the federal maximum. Higher housing costs can mean a larger protected income.
Income Allowance vs. Resource Allowance: Don't Confuse the Two
Families routinely blur the MMMNA with the community spouse resource allowance, but they protect different things. The MMMNA protects monthly income; the resource allowance protects a pool of countable assets.
The resource side — the lump sum of savings, investments, and accounts the community spouse may keep — is governed by its own federal minimum and maximum. We walk through that figure in our explainer on how the CSRA is calculated and the current ceiling in the federal CSRA maximum for 2026.
Here is the distinction that matters at the kitchen table. The resource allowance is measured once, around the Medicaid snapshot date; the income allowance is an ongoing monthly transfer that continues for as long as the institutionalized spouse qualifies.
| Feature | Income allowance (MMMNA / CSMIA) | Resource allowance (CSRA) |
|---|---|---|
| Protects | Monthly income | Countable assets and savings |
| Measured | Monthly, ongoing | Once, near the snapshot date |
| Federal range | Minimum (150% FPL) to maximum cap | Federal minimum to federal maximum |
| Question it answers | How much income can the at-home spouse keep? | How much in assets can the at-home spouse keep? |
Income-First and Resources-First States
One more wrinkle determines how generous a state is when the standard allowance still leaves a community spouse short. States fall into two camps: income-first and resources-first.
In an income-first state — the majority — Medicaid expects the couple to use the institutionalized spouse's diverted income to reach the MMMNA before allowing the community spouse to keep extra assets. In a resources-first state, the spouse may be permitted to retain additional resources, which can generate income, before tapping the diverted income.
The distinction sounds technical, but it can change how much a family keeps by a meaningful margin. Which rule your state follows is something to confirm locally, because it shapes the order in which the calculations are run.
When the Standard Allowance Isn't Enough
The federal maximum is not always the end of the story. A community spouse who cannot make ends meet on the standard allowance has two avenues to ask for more.
The first is a Medicaid fair hearing, where the spouse argues that exceptional circumstances — often unusual medical or housing expenses — create financial duress that the ordinary allowance does not cover. A hearing officer can order a higher MMMNA.
The second is a court order for spousal support. If a court has ordered one spouse to pay support to the other, Medicaid generally must honor that order, which can raise the diverted income above the federal cap.
Both routes are fact-specific and procedural, and the standard of proof is not trivial. This is the point where many families consult an elder-law attorney rather than navigate the process alone.
What This Means for Your Family
The headline fear — that a nursing home and Medicaid will strip the at-home spouse of the household's income — is not how the rules actually work. Federal law deliberately protects a baseline of income for the spouse who remains at home.
The practical takeaways are worth restating. The community spouse keeps income in their own name, can receive a diverted share of the institutionalized spouse's income up to the MMMNA, and may qualify for more through the excess shelter allowance or a fair hearing.
Because the federal figures change every year and because states administer the program differently, the safest move is to confirm the current numbers and your state's rules before you plan around them. You can start with our primer on the minimum monthly maintenance needs allowance and, when you are ready for individualized guidance, our directory to find an elder-law attorney.
Remember that the income allowance and the resource allowance work together, not in place of each other. Understanding both is how a family preserves the most while still qualifying the spouse who needs care.
