South Dakota Medicaid Income Limit for Nursing Home Care

The Hard Cap: $2,982 Per Month in 2026

South Dakota sets its long-term care Medicaid income limit at 300% of the Federal Benefit Rate, which works out to $2,982 per month in 2026. This is a gross income figure — Social Security, pensions, VA benefits, annuity payments, rental income, and any other recurring income all count before deductions.

The critical distinction: South Dakota is a strict income-cap state, not a medically needy state. In medically needy states, applicants whose income exceeds the limit can subtract medical expenses to qualify. South Dakota does not allow this for long-term care. If gross income hits $2,983, the applicant is flatly ineligible for nursing home Medicaid — unless they establish a Qualified Income Trust.

How a Qualified Income Trust Solves the Problem

A Qualified Income Trust, commonly called a Miller Trust, is a special irrevocable trust that channels the applicant's income through a dedicated bank account. The mechanics are rigid:

1. Funding: Only the applicant's personal income flows into the trust. No personal savings, family contributions, or other assets can be deposited.
2. Distribution order: Each month, the trustee pays out in a fixed sequence — the $100 personal needs allowance (plus up to the first $75 of gross earned income), health insurance premiums (including Medicare Part B and any supplement), any income diversion to a community spouse, and finally the remaining patient liability to the nursing facility or HOPE waiver provider.
3. State payback: The trust document must name the South Dakota Department of Social Services as the primary remainder beneficiary. When the recipient dies, any balance in the trust reimburses the state for Medicaid expenditures.

The trust must comply with SDCL 67:46:05:33.01. DSS does not accept generic online trust templates — an elder law attorney familiar with South Dakota's specific requirements needs to draft it. Attorney fees for a Miller Trust typically run $1,500 to $3,500.

Common Income Sources That Push Families Over the Cap

Many South Dakota families don't realize their parent is over the limit until they sit down to add up income sources:

• Social Security retirement: The average benefit in South Dakota runs around $1,900/month, but many recipients draw more.
• Federal or state pensions: A combined Social Security check and a modest pension easily clears $2,982.
• Required minimum distributions: South Dakota counts retirement account RMDs as income. A 401(k) or IRA in distribution mode can push total income well past the cap.
• VA pension benefits: Aid & Attendance and Housebound benefits count toward gross income for Medicaid purposes.

What Happens to Income After Approval

Once approved, the recipient keeps the $100 monthly personal needs allowance, plus up to the first $75 of gross earned income, for personal spending. The remaining income goes toward health insurance premiums, any permitted spousal diversion, and care costs. If the recipient has a spouse living at home whose own income falls below $2,705 per month (the 2026 Minimum Monthly Maintenance Needs Allowance floor), a portion of the institutionalized spouse's income can be diverted to bring the at-home spouse up to that floor — or up to $4,066.50 if they have high shelter costs.
