South Dakota Medicaid income limits work as a hard cap for long-term care: earn one dollar over $2,982 a month and you're over the line, with no spend-down to fall back on. South Dakota is an income-cap state, so an applicant whose gross monthly income exceeds that ceiling has to route the excess through a Miller Trust to qualify, not whittle it down with medical bills.
This guide walks through the 2026 income and asset rules for South Dakota Medicaid long-term care: the income cap and how a Miller Trust clears it, the $2,000 asset limit, what a nursing-home resident keeps, and what the spouse at home is protected from. South Dakota runs its program through the South Dakota Department of Social Services (DSS).
The income cap is the South Dakota story
For long-term-care Medicaid, South Dakota sets the income limit at $2,982 per month, equal to 300% of the 2026 SSI Federal Benefit Rate of $994. That figure applies to nursing-facility coverage and to the home-and-community-based services (HCBS) waivers that pay for care outside a facility.
Here's what makes South Dakota different from a spend-down state. The cap is counted on gross income, and it's a true ceiling. In a medically needy state, someone over the income standard can still qualify by incurring enough medical bills each month to "spend down" the excess. South Dakota does not offer that route for long-term care. If your gross income is $2,983, you are over the line, even though you obviously can't afford a nursing home that runs several times that.
That sounds like a trap, and for years it was. The fix is a legal one, and South Dakota recognizes it.
How the Miller Trust clears the cap
A Qualified Income Trust, almost always called a Miller Trust, is the tool that lets an over-income applicant qualify anyway. You establish the trust, and each month the income above the cap is deposited into it. Income held in a properly drafted Miller Trust doesn't count toward the $2,982 limit, so the applicant is treated as income-eligible.
The trust isn't a loophole or a way to shelter money for heirs. It's tightly controlled:
- The money in the trust can only be spent in a set order, mostly toward the cost of the applicant's care and certain allowances.
- The state must be named as the remainder beneficiary, so whatever's left when the recipient dies goes to South Dakota Medicaid up to what it paid.
- It has to be set up correctly before or in the month coverage is needed, which is why this is elder-law-attorney territory, not a do-it-yourself form.
The practical takeaway: being over the income cap in South Dakota does not mean you're disqualified. It means you need a Miller Trust. A single dollar of excess income is a paperwork problem, not a dead end.
What a nursing-home resident keeps
When South Dakota Medicaid pays for nursing-facility care, the resident contributes nearly all of their monthly income toward the cost of care. What stays with them is the Personal Needs Allowance (PNA), money set aside for the resident's own small expenses like clothing, a haircut, or a phone. South Dakota sets its PNA at $100/month.
That $100 is worth noticing. The federal floor has sat at $30/month since 1988, and most states land somewhere between $50 and $80. South Dakota's $100 is among the more generous figures in the country, which leaves a resident a bit more breathing room than the typical state allows. (For the national picture on how the allowance works and where it gets deducted, see our explainer on the Medicaid personal needs allowance.)
The five-year look-back
South Dakota reviews asset transfers made in the 60 months before a long-term-care application. Giving away money or property for less than fair market value during that window, signing a house over to a child, gifting a grandchild a down payment, can trigger a penalty period during which Medicaid won't pay for long-term-care services, even when you otherwise qualify.
There are legitimate exceptions (transfers between spouses, transfers to a disabled child, certain caregiver-child home transfers) and legitimate planning approaches, but anything done inside the five-year window deserves an elder-law attorney's review first. If long-term care is on the horizon for someone in your family, talk to a professional before moving assets. For the broader toolkit, see our guide to Medicaid planning strategies.
A worked example: South Dakota Medicaid income limits in practice
Protecting the spouse who stays home
When one spouse needs long-term care and the other stays in the community, federal spousal-impoverishment rules keep the at-home spouse from being left with nothing. South Dakota applies the federal maximums for 2026.
| Protection | 2026 Amount | What it does |
|---|---|---|
| Community Spouse Resource Allowance (CSRA) | Half the couple's countable assets, up to $162,660; minimum $32,532 | The most in countable assets the at-home spouse may keep, separate from the applicant's $2,000 limit. |
| Minimum Monthly Maintenance Needs Allowance (MMMNA) | Up to $4,066.50/month | The most monthly income the at-home spouse may keep; income can be shifted from the applicant to reach it. |
| Home-equity limit | $752,000 | Equity in the primary residence above this amount is countable for long-term-care eligibility. |
So a married couple stands in a very different position from a single applicant. The community spouse can hold up to $162,660 in countable assets and bring monthly income up to $4,066.50 while the other spouse receives Medicaid-funded care. The $2,000 asset limit applies to the spouse who needs care, not to the couple's whole net worth.
After death: estate recovery
Like every state, South Dakota runs a Medicaid estate-recovery program. After a recipient who was 55 or older and received long-term-care services dies, the state may seek repayment from the estate, unless the recipient is survived by a spouse or a minor, blind, or disabled child. Federal exceptions apply, and an undue-hardship waiver exists. For how recovery works and where families have room to plan, see our Medicaid estate recovery explainer.
How to apply in South Dakota
South Dakota Medicaid is administered by the South Dakota Department of Social Services. You have two main ways to apply:
- Online through the DSS Economic Assistance portal at eaportal.sd.gov, which handles Medicaid and other assistance programs together.
- By phone through DSS at 1-605-773-3165.
Long-term-care applicants also go through a level-of-care screening to confirm they need nursing-facility-level services. Apply even if you think you're over the income limit. The income cap is real, but a Miller Trust clears it, and the asset rules exempt more than people expect, so many who assume they're disqualified are not.
Frequently Asked Questions
For long-term care (nursing facility and HCBS waivers), the 2026 income cap is $2,982/month, set at 300% of the SSI Federal Benefit Rate. It's a hard ceiling on gross income, not a spend-down threshold. An applicant whose income exceeds it must establish a Miller Trust to qualify.
$2,000 in countable assets for a single applicant, or $3,000 for a married couple when both spouses apply. The home (subject to an equity cap), one vehicle, household goods, and prepaid burial arrangements are exempt from the count.
Yes, if your income exceeds the cap. South Dakota is an income-cap state with no medically needy spend-down for long-term care, so an over-income applicant must route the excess into a Qualified Income Trust (Miller Trust) each month. Income held in the trust doesn't count toward the $2,982 limit.
For 2026, the at-home (community) spouse can keep up to $162,660 in countable assets (the Community Spouse Resource Allowance, minimum $32,532) and bring monthly income up to $4,066.50 (the Minimum Monthly Maintenance Needs Allowance). The home is generally protected up to $752,000 of equity.
A Personal Needs Allowance of $100/month, which is higher than the federal $30 floor and more than most states allow. The rest of the resident's monthly income goes toward the cost of care, after deductions for a community spouse and certain health-insurance premiums.
