South Dakota Medicaid Home Equity Limit

The $752,000 Equity Limit

South Dakota exempts a primary home from Medicaid's $2,000 countable asset limit — but only up to $752,000 in equity (the 2026 CMS-adjusted threshold). Equity is the home's fair market value minus any outstanding mortgage or lien. If a parent's home is worth $800,000 with no mortgage, the full value exceeds the limit and the home becomes a countable asset that must be addressed before Medicaid will approve the application.

The exemption has two additional conditions. The applicant must either live in the home with an intent to return, or a spouse, minor child, or blind or disabled child must reside there. If an applicant is in a nursing home permanently and no qualifying person lives in the home, the exemption can be lost.

For most South Dakota families, the $752,000 threshold is not a concern — median home values across much of the state fall well below that level. But families with higher-value properties in Sioux Falls, Rapid City, or those with large rural homesteads that include agricultural land in the same parcel may need to evaluate whether their equity clears the limit.

Protecting the At-Home Spouse's Income

When one spouse enters a nursing home and the other remains at home, South Dakota's income rules work differently than many families expect. The core principle is the "name-on-the-check" rule: each spouse keeps the income that is paid in their own name. Social Security, pensions, and retirement distributions belong to the person whose name is on the payment.

The problem arises when the at-home spouse (the community spouse) has little or no income of their own. A spouse who was a homemaker, who worked part-time, or who relied on the institutionalized spouse's pension may not have enough personal income to cover basic living expenses.

The Minimum Monthly Maintenance Needs Allowance (MMMNA) addresses this. In South Dakota, the MMMNA floor is $2,705.00 per month (effective July 1, 2026 through June 30, 2027). If the community spouse's personal monthly income falls below this amount, they are entitled to an "income diversion" — a portion of the institutionalized spouse's income is redirected to bring the community spouse up to the MMMNA floor.

If the community spouse has exceptionally high shelter and utility costs, the allowance can be increased up to a maximum of $4,066.50 per month. This adjustment is calculated using a formula that compares actual shelter costs against a standard utility allowance.

How Income Diversion Reduces Patient Liability

The income diverted to the community spouse reduces the institutionalized spouse's patient liability — the amount they owe to the nursing home each month. The calculation works like this:

1. Start with the institutionalized spouse's total monthly income
2. Subtract the $100 personal needs allowance
3. Subtract health insurance premiums (Medicare Part B, supplemental plans)
4. Subtract the community spouse income allowance (the difference between the MMMNA floor and the community spouse's own income)
5. The remainder is the patient liability — paid to the nursing home

A higher community spouse allowance means a lower patient liability, which means the nursing home receives less from the resident and more from Medicaid. The patient-liability calculation is set by DSS, not negotiated with the facility, so the family should provide the DSS determination to the nursing home.

The CSRA and the Home Equity Exemption Work Together

The Community Spouse Resource Allowance (CSRA) protects up to $162,660 in countable assets for the at-home spouse. The home equity exemption protects the home itself up to $752,000. These protections run in parallel — the home's value does not count against the CSRA as long as the community spouse lives there.

For a couple with $300,000 in savings and a $400,000 home, the picture looks like this:

• The home is exempt (under the $752,000 limit and the spouse lives there)
• The community spouse keeps up to $162,660 of the countable assets under the CSRA
• The remaining $137,340 must be spent down to reach the $2,000 asset limit for the institutionalized spouse

South Dakota calculates the CSRA before applying any Long-Term Care Partnership Program credits. If either spouse held a qualified Partnership long-term care insurance policy, the policy's benefit amount is added on top of the CSRA — potentially protecting additional assets beyond the $162,660 ceiling.

The Post-Death Risk

While the home is protected during the community spouse's lifetime, South Dakota's expanded estate recovery under SDCL 28-6-23 can reach the home after any applicable deferral ends. Recovery must be deferred while a surviving spouse is alive, and while a minor, blind, or disabled child of the deceased is alive. But once those conditions no longer apply, DSS can file a claim against the estate — including the home — for every dollar Medicaid paid for the institutionalized spouse's care.

Families who want to protect the home from post-death recovery need to plan separately for that — through strategies like a Medicaid Asset Protection Trust funded outside the lookback window, or the caregiver child exception if an adult child meets the residency and caregiving requirements.

The South Dakota Medicaid Long-Term Care & Asset Protection Guide includes worksheets for calculating the community spouse income allowance, the CSRA, and the patient liability — the three numbers that determine how much the family keeps and how much goes to the nursing home each month.
