Spousal Impoverishment Protections: How CSRA and MMMNA Actually Work
A spouse at home does not have to spend down to nothing before the other qualifies for nursing home Medicaid. The amount protected depends on a count taken on one specific date.
When one spouse needs nursing home Medicaid, federal law protects the spouse who stays home (the "community spouse") in two ways. The Community Spouse Resource Allowance (CSRA) lets that spouse keep the greater of $32,532 or half the couple's countable assets, up to $162,660 in 2026. The Minimum Monthly Maintenance Needs Allowance (MMMNA) guarantees a monthly income of $2,705 to $4,066.50, depending on housing costs. The community spouse does not have to be low-income to get either one. The CSRA is based on the couple's assets on a "snapshot" date at the start of the nursing home stay, not on what is left when you apply.
These protections apply whether or not you ask for them. The CSRA amount, though, depends on a count of assets as of one date, and families who do not get that count on record can end up keeping less than the law allows.
Two protections, doing two different jobs
Congress created these rules in the Medicare Catastrophic Coverage Act of 1988. Medicaid's income and asset limits were written for one person. Applied to a married couple, they forced the couple to spend nearly everything, including what the spouse at home needed to live on, before the other spouse qualified.
The law fixed this with two separate allowances:
- CSRA protects a share of the couple's combined assets when the application is decided.
- MMMNA protects the community spouse's monthly income after the other spouse is approved and in care.
A couple can use one or both. Neither has an income or asset test for the community spouse. The allowances exist to keep that spouse from becoming poor, so there is no requirement to be poor already.
CSRA: the asset protection, and the part everyone misses
For 2026, the community spouse keeps the greater of $32,532 or half the couple's countable assets, up to $162,660. The spouse applying for Medicaid keeps a separate $2,000. The home is generally not counted at all while the community spouse lives in it.
| Couple's countable assets on the snapshot date | Half | Community spouse keeps (2026) |
|---|---|---|
| $50,000 | $25,000 | $32,532 (the floor) |
| $200,000 | $100,000 | $100,000 |
| $400,000 | $200,000 | $162,660 (the ceiling) |
The date of the count matters as much as the formula. Under 42 U.S.C. § 1396r-5, the couple's countable resources are totaled as of the first day of the institutionalized spouse's first continuous stay of at least 30 days. That is the snapshot date. It is not the date of the Medicaid application, and it is usually months earlier.
The half is calculated from the snapshot total. Money spent on care after that date, or lost in a market drop, does not reduce the CSRA.
Take a couple with $200,000 on the day the husband enters a nursing home. They pay privately for a year and apply for Medicaid with $120,000 left. The wife's CSRA is half of the snapshot total, which is $100,000. If nobody documented the snapshot and the state counts from the application date, half is $60,000. She would keep $40,000 less than the law allows.
To prevent this, either spouse can ask the state for a resource assessment when the nursing home stay begins. You do not have to file a Medicaid application to get one. The assessment puts the snapshot total on record. Request it in the first weeks of the stay, and keep bank and account statements for the month of admission.
CSRA Formula (2026)
Greater of $32,532 or half the couple's countable assets, capped at $162,660. Separate from the applicant's own $2,000 limit.
The Snapshot Date
Assets are valued as of the start of the first continuous stay of 30 days or more, not the application date. Spending after that date doesn't lower the CSRA.
MMMNA Range (2026)
$2,705 to $4,066.50/month, based on the community spouse's housing costs. Alaska and Hawaii use higher minimums.
Request It Early
Either spouse can request a resource assessment before applying. It records the snapshot total while the statements are easy to get.
MMMNA: the income protection, and how it adds up
The MMMNA is a monthly income floor for the community spouse. If that spouse's own income is at or above the floor, nothing changes. If it is below, the shortfall is taken from the nursing home spouse's income before that income goes toward the cost of care.
For 2026, the minimum is $2,705 a month in the 48 contiguous states and DC. Alaska ($3,381.25) and Hawaii ($3,111.25) are higher. A community spouse whose housing costs are above a standard amount, set at 30% of the minimum, gets a higher allowance, up to $4,066.50.
Suppose the wife at home has $1,800 a month of her own income and her housing costs are below the standard. Her floor is $2,705, so $905 a month of her husband's income goes to her instead of to the nursing home.
If the maximum is still not enough, for example because of a large mortgage or heavy medical costs, the community spouse can request a fair hearing to ask for more. Some states also allow a court order to set a higher amount.

Myths worth correcting
"The community spouse has to prove they're low-income too." False. Both allowances apply whatever that spouse's income or resources are.
"The home counts against the asset limit." False. The home is excluded while the community spouse lives there, and the CSRA comes on top of that.
"These protections happen automatically." The law guarantees them, and the MMMNA is applied as part of the case. The CSRA is the risk. An application filed long after admission can be calculated on the smaller amount left at that point unless the snapshot total is documented.
Where states differ
Most states use the half-of-assets formula. Alaska, Florida, Maine, Mississippi and California's Medi-Cal long-term care program skip the 50% step and let the community spouse keep up to the full ceiling. In those states, the couple with $200,000 in the example above could protect $162,660 instead of $100,000. Ask a caseworker or elder law attorney which method your state uses.
Frequently Asked Questions
Does the community spouse have to be low-income to keep these protections?
No. CSRA and MMMNA apply whatever the community spouse's own income or assets are. They are federal protections tied to the marriage and to the other spouse's Medicaid application, and there is no separate needs test for the spouse at home.
What is the CSRA "snapshot date"?
It is the date the couple's countable resources are totaled for the CSRA: generally the first day of the institutionalized spouse's first continuous stay of at least 30 days. The CSRA is based on that total. Spending or gaining assets after that date does not change it.
Can we request a resource assessment before applying for Medicaid?
Yes. Either spouse can ask the state for a resource assessment when the nursing home stay begins, without filing a Medicaid application. Doing it early puts the snapshot total on record before care costs reduce the couple's savings.
Does the home count toward the CSRA asset limit?
No. The primary home is generally excluded from countable resources while the community spouse lives there. The CSRA is in addition to the home.
Do all states calculate CSRA the same way?
Most use the standard formula: half the couple's countable resources, with a floor and a ceiling. Alaska, Florida, Maine, Mississippi and California's Medi-Cal long-term care program let the community spouse keep up to the full ceiling without the 50% split.
This article explains general federal spousal impoverishment rules as of October 2026. Some states calculate the CSRA differently, and resource assessment procedures vary by state. This is general educational information, not legal advice. Request a resource assessment and confirm your state's method with your state Medicaid agency or an elder law attorney before you file an application.
