South Dakota Medicaid Spousal Impoverishment 2026: CSRA Guide

When one spouse needs nursing facility care and the other stays home, South Dakota Medicaid does not make the couple spend down everything before coverage begins. The federal spousal impoverishment rules protect the at-home spouse's assets and income, and this guide walks you through exactly how much your spouse can keep in 2026.

How South Dakota Medicaid Spousal Impoverishment Works

When one spouse enters a nursing facility or qualifies for a home- and community-based services (HCBS) waiver, South Dakota Medicaid applies the federal spousal impoverishment protections found at 42 U.S.C. § 1396r-5. The idea behind these rules is simple: the law does not want the healthy spouse left destitute because their partner needs long-term care. So the protections split into two parts, one that shields a share of the couple's assets and one that shields a share of the couple's income.

South Dakota Medicaid is administered by the Department of Social Services (DSS), and it operates as an income-cap state. To qualify for long-term care coverage, the institutionalized spouse must have income at or below $2,982/month, which is 300% of the 2026 SSI Standard Benefit Amount. An applicant whose income runs over that limit is not simply disqualified, but must route the excess through a Qualified Income Trust (also called a Miller Trust) before Medicaid will pay for care.1

It helps to keep the vocabulary straight from the start. The spouse entering long-term care is the institutionalized spouse. The spouse who remains at home is the community spouse. The community spouse's asset and income protections are calculated on their own track, separate from the income test that decides whether the institutionalized spouse is eligible in the first place.

How Much Can the Community Spouse Keep? (CSRA vs. MMMNA)

South Dakota's protections come in two flavors, and families often confuse them, so here is the contrast at a glance. One rule protects a pool of savings; the other protects a monthly income stream. The table below shows how they differ.

The rest of this guide takes each protection in turn, starting with the asset rule (the CSRA) and then the income rule (the MMMNA).1

How Much of the Couple's Savings Can the Spouse Keep? (CSRA)

The Community Spouse Resource Allowance (CSRA) is the portion of the couple's countable assets that the community spouse gets to keep when the institutionalized spouse applies for South Dakota Medicaid long-term care coverage. Everything else counts toward the institutionalized spouse's own eligibility and generally has to be spent down first.1

The Snapshot Date

Before South Dakota calculates the CSRA, the program takes a snapshot of the couple's total countable assets. The snapshot date is the first day of a continuous period of institutionalization, which is typically the date the institutionalized spouse enters a nursing facility for a stay expected to last at least 30 continuous days.

The snapshot date matters more than most families expect. The CSRA is based on that frozen figure, not on the couple's asset position at the time of the Medicaid application, so the value of the couple's accounts on the snapshot day is the number that governs the whole calculation. Any planning a couple wants to do needs to happen with the snapshot date in mind.

The Half-of-Assets Formula

South Dakota applies the standard federal formula: the community spouse keeps half of the couple's total countable assets at the snapshot date, subject to a minimum and a maximum. This is a half-of-assets state, not a state that hands every community spouse the full federal ceiling regardless of what the couple actually owns.1

For 2026, the floor and ceiling on that half-of-assets result are:1

• Minimum CSRA: $32,532 (if half the assets is less than this, the community spouse still keeps $32,532).1
• Maximum CSRA: $162,660 (if half the assets exceeds this, the community spouse keeps $162,660).1

Because South Dakota uses the full federal ceiling of $162,660, couples with substantial savings get the most protection the law allows before spend-down begins. But the amount an individual community spouse actually keeps still depends on the couple's assets: half of a modest estate can fall below the ceiling and is protected only up to that half, and the floor of $32,532 protects couples with very little.1

A worked example illustrating the formula:

The figures below are hypothetical and shown only to illustrate how the calculation works. They are not a real case and not a prediction of your own result.

A couple in Sioux Falls has $150,000 in joint savings and a $60,000 CD, for a total of $210,000 in countable assets. Half of that is $105,000, which falls between the floor and the ceiling, so the community spouse keeps $105,000. The institutionalized spouse's share is the other $105,000. Because South Dakota allows a single applicant just $2,000 in countable assets, roughly $103,000 has to be spent down before Medicaid eligibility is established.1

What Counts as a Countable Asset?

Both spouses' assets are pooled for the snapshot, regardless of whose name is on the account. Countable assets generally include:

• Checking and savings accounts
• CDs and money market funds
• Stocks, bonds, and mutual funds
• Both spouses' IRAs and 401(k)s
• Cash value of certain life insurance policies (a small per-policy face-value floor is exempt; confirm the current figure with DSS)
• Non-home real estate

Assets that are exempt include the primary home, one vehicle, household goods and personal effects, and prepaid irrevocable burial contracts. Because the treatment of a specific asset can turn on details, it is worth confirming any uncertain item with DSS before you assume it counts.

How Much Income Can the At-Home Spouse Keep? (MMMNA)

The Minimum Monthly Maintenance Needs Allowance (MMMNA) is the income protection for the at-home spouse. Where the CSRA guards a pool of savings, the MMMNA guards a monthly income floor, making sure the community spouse has enough coming in each month to cover basic living expenses.1

For 2026, South Dakota applies the federal range:1

• Floor (minimum MMMNA): $2,705.00/month (effective 7/1/2026 through 6/30/2027).1
• Ceiling (maximum MMMNA): $4,066.50/month (effective 1/1/2026 through 12/31/2026).1

The Name-on-the-Check Rule

Under federal law (42 U.S.C. § 1396r-5(b)(2)), the community spouse keeps all of their own income, no matter how large it is. Income paid in the community spouse's name does not factor into the applicant's Medicaid eligibility at all. Only the institutionalized spouse's income flows toward the nursing facility cost, which is why the name on the check ends up mattering so much when a couple has income in both names.

Income Diversion

When the community spouse's own income falls below the MMMNA floor, South Dakota allows an income diversion from the institutionalized spouse's income to bring the community spouse up to that floor. This is the mechanism that keeps the at-home spouse from being left short when most of the household income was in the institutionalized spouse's name.

Here is how the money moves. The institutionalized spouse's income is first reduced by the Personal Needs Allowance ($100/month in South Dakota), then by Medicare premiums and other allowable deductions.1 From what remains, enough is diverted to the community spouse to reach the MMMNA floor. Whatever is left after that diversion is the patient liability, which is paid to the nursing facility, and South Dakota Medicaid covers the rest of the bill.

Worked example illustrating income diversion:

The figures below are hypothetical and shown only to illustrate how the calculation works. They are not a real case and not a prediction of your own result.

Suppose the community spouse receives $1,400/month from Social Security, and the MMMNA floor is $2,705.00/month, leaving her short by $1,305.00/month.1 The institutionalized spouse receives $2,300/month from Social Security and a pension. After the $100 Personal Needs Allowance and his Medicare Part B premium are deducted, the remaining income is available to be applied.1 Of that, $1,305.00 is diverted to the community spouse to close her shortfall, and the balance becomes the patient liability paid to the facility. South Dakota Medicaid covers the difference. (Because the standard Medicare Part B premium is set annually by the federal government, confirm the current amount with DSS or Medicare before relying on a figure.)

Reaching the MMMNA Ceiling

The community spouse can reach the $4,066.50 ceiling when she has excess shelter costs, meaning her housing costs run above a federal shelter standard.1 Actual rent or mortgage, property taxes, homeowners insurance, and utilities that exceed that standard raise her allowable income toward the ceiling. The federal shelter standard is reset periodically on a federal clock, so rather than rely on a fixed number here, confirm the current figure with DSS when you estimate the community spouse's income ceiling.

Is the Home at Risk in South Dakota?

The primary residence is exempt from Medicaid eligibility calculations as long as the community spouse lives there, so in the typical married-couple case the home is not something the couple has to spend down to qualify.1

Federal law does set a home-equity cap, above which the equity can affect eligibility. For 2026, the federal minimum equity cap, which most states apply, is $752,000.2 When the community spouse lives in the home, that cap rarely comes into play, but it can matter for a single applicant with a high-value home and no spouse at home.

South Dakota applies a 60-month lookback on asset transfers.1 If any assets were given away or transferred for less than fair value within five years before the application, consult an elder law attorney, because those transfers can create a penalty period.

Which Assets Are Exempt?

Beyond the home, several asset categories are excluded from the Medicaid eligibility calculation:

• Primary residence (exempt while the community spouse lives there, subject to the federal home-equity cap)2
• One vehicle of any value
• Household goods and personal effects
• Prepaid irrevocable burial contracts
• Burial plots for the applicant and immediate family

Does South Dakota Require a Miller Trust?

Because South Dakota is an income-cap state, an institutionalized spouse whose gross monthly income exceeds $2,982 must establish a Qualified Income Trust (Miller Trust) before South Dakota Medicaid will pay for long-term care.1 There is no medically needy spend-down for long-term care here, so the trust is the mechanism the state uses instead.

The way it works is that each month the income above $2,982 is deposited into the trust, and from that account the trustee pays out the Personal Needs Allowance, the community spouse income diversion, Medicare premiums, and the patient liability.1 The trust must be irrevocable and name the South Dakota DSS as the remainder beneficiary, and an elder law attorney should draft it so the terms meet the state's requirements.

How Do You Apply for South Dakota Medicaid Long-Term Care?

South Dakota Medicaid for long-term care is administered by the South Dakota Department of Social Services (DSS), and the CSRA and MMMNA are calculated as part of the nursing home Medicaid application. A couple does not have to wait until they are ready to file a full application to get clarity, though. Either spouse can request a resource assessment on its own, which locks in the snapshot figure and tells the couple where they stand before any spend-down begins.

The application itself generally follows the sequence below. For a full walkthrough, see the South Dakota Medicaid how-to-apply guide.

What Medicaid Planning Strategies Should Couples Consider?

South Dakota's use of the full federal CSRA ceiling gives couples a solid baseline, but families whose countable assets exceed the $162,660 ceiling sometimes have room for additional planning.1 A few of the more common approaches:

• Converting countable assets to exempt ones: making home improvements, prepaying an irrevocable burial contract, or purchasing a needed vehicle can shift value out of the countable column.
• Community-spouse annuities: converting excess countable assets into an income stream using an irrevocable annuity that meets Deficit Reduction Act of 2005 requirements.
• Fair hearing: if the CSRA does not generate enough income to meet the MMMNA, a fair hearing may increase the resource allowance in appropriate cases.

For broader options, see Medicaid planning strategies. Couples with significant assets above the CSRA ceiling should consult a South Dakota-licensed elder law attorney before applying, because the right sequence of steps depends heavily on the specific facts.
