Free Health Insurance South Dakota: Your 2027 Marketplace & Medicaid Guide
Free health insurance in South Dakota isn't a gimmick — it's a premium tax credit, or it's South Dakota Medicaid. South Dakota uses HealthCare.gov for 2027, and open enrollment runs November 1, 2026 – January 15, 2027. Here are the 2027 income limits, the Medicaid work requirement that starts January 1, 2027, and how to lock in coverage by December 15.

Quick answer: South Dakota adults 19–64 earning up to about 138% of the poverty level (about $22,025 for one person) may qualify for South Dakota Medicaid, which adds a work requirement on January 1, 2027. Above that, HealthCare.gov tax credits can bring some plans to $0. Open enrollment runs November 1, 2026 to January 15, 2027.

Free health insurance South Dakota residents can actually get comes from two places. The first is a premium tax credit on HealthCare.gov, the federally facilitated Marketplace that CMS lists for South Dakota in plan year 2027. The second is South Dakota Medicaid, run by the Department of Social Services (DSS), which covers lower-income adults through its Medicaid Expansion Adult Group. If your household income falls between 100% and 400% of the federal poverty level (FPL), the credit pays part or all of your monthly premium directly to the insurance company, and at lower incomes that can mean a $0-premium plan. The same rules apply statewide, from Sioux Falls and Rapid City to Aberdeen, Brookings, and Watertown.
Here's what changed for 2027. The extra "enhanced" tax credits of 2021–2025 expired at the end of 2025, and they are not back for 2027 under current law unless Congress acts. Credits are smaller than they were in 2025, and the 400% FPL cliff is back: earn $1 over the line and your credit is $0. South Dakota Medicaid is changing too. DSS starts a community engagement (work) requirement on January 1, 2027, and a proposed constitutional amendment on the November 2026 ballot would end expanded coverage if federal funding for it drops below 90%.

South Dakota Health Insurance Income Limits for 2027
Marketplace savings for 2027 coverage are based on the 2026 federal poverty guidelines: $15,960 for one person and $33,000 for a family of four. The IRS sets how much of your income you're expected to pay for the benchmark Silver plan, from 2.15% to 10.22% as income rises, and the tax credit covers the rest. Here's where South Dakota households typically land:
| 2027 Household Income | Household of 1 | Household of 4 | What You Typically Get |
|---|---|---|---|
| Up to ~138% FPL | Up to ~$22,025 | Up to ~$45,540 | Likely South Dakota Medicaid (Adult Group) for adults 19–64; starting in 2027, adults who aren't excluded must also meet the work requirement (see below) |
| ~138–150% FPL | $22,025–$23,940 | $45,540–$49,500 | The biggest credits — you pay no more than 4.30% of income for the benchmark Silver plan, and 94% CSR Silver plans are available |
| 150–200% FPL | $23,940–$31,920 | $49,500–$66,000 | You pay 4.30%–6.78% of income for benchmark Silver, plus 87% CSR Silver plans that shrink deductibles |
| 200–250% FPL | $31,920–$39,900 | $66,000–$82,500 | You pay 6.78%–8.66% of income; 73% CSR Silver plans still trim cost sharing |
| 250–400% FPL | $39,900–$63,840 | $82,500–$132,000 | You pay 8.66%–10.22% of income — credits taper but still cut real dollars off the premium |
| Over 400% FPL | $63,840+ | $132,000+ | No premium tax credit for 2027 under current law — full-price plans, so shopping smart matters most |
Family-of-four figures are derived from the 2026 guidelines, so treat them as approximate. DSS describes Medicaid Expansion enrollees as having income up to 138% FPL and publishes its own limits as gross monthly income: $1,835 a month for a household of one. Medicaid uses the current year's poverty guidelines, so its dollar limits will update once the 2027 guidelines take effect. You can compare every state in our Medicaid income limits guide.
Income means your projected 2027 household income — W-2 wages, 1099 and gig income, self-employment, everything. Getting it right matters more than ever: for tax years after 2025 there is no cap on repaying excess advance credits, so a low estimate can mean paying back the full difference at tax time. Starting January 1, 2027, federal law also limits premium tax credits to fewer groups of lawfully present immigrants (green-card holders, Cuban and Haitian entrants, and COFA migrants remain eligible).

South Dakota Medicaid in 2027: Expanded, With New Rules Coming
South Dakota has expanded Medicaid. According to the Attorney General's 2026 ballot statement, voters approved Constitutional Amendment D in the 2022 general election, which requires Medicaid coverage for people over 18 and under 65 with income at or below 133% FPL, plus a 5% income disregard. DSS calls the group the Medicaid Expansion Adult Group: adults ages 19–64, with or without private health insurance, who meet the income limits and other rules. It includes regular checkups, dental care, and vision care. DSS lists a maximum gross monthly income of $1,835 for a household of one.
Pregnancy and children
DSS lists the same $1,835 monthly limit for pregnant women in a household of one, and pregnancy coverage continues for 12 months after the birth. Newborns of mothers covered by Medicaid are covered to age one. Children can qualify through Medicaid or the Children's Health Insurance Program (CHIP), which DSS offers at higher income limits than adult coverage, even to children who already have private insurance.
New for 2027: the community engagement (work) requirement
DSS says that starting January 1, 2027, some adults enrolled in Medicaid Expansion must show they're completing community engagement activities to keep their coverage. The standard is at least 80 hours a month of work, job training, community or volunteer service, or school at least half-time, or a combination of these. It applies to adults 19–64 who are eligible for Medicaid Expansion, unless they're excluded.
New applicants who apply on or after January 1, 2027 must show 80 hours during the month before they apply. Current enrollees face the requirement at their first regularly scheduled renewal in 2027 and must show 80 hours in at least one month since their last renewal. DSS checks the data it already has first. It mailed a Community Engagement Fact Sheet (EA400) to all Medicaid Expansion recipients in August 2026 and began notifying affected enrollees in September 2026. From January 1, 2027, you can check your status in DSS notices or the BEES portal.
Who is excluded: former foster youth under 26 who were in care and on Medicaid at 18; American Indians and Alaska Natives, including people eligible for Indian Health Service care; caregivers of a child 13 or younger or of a person with a disability; veterans with a total disability rating; people who are pregnant or eligible for postpartum Medicaid coverage; people who are medically frail or have a disability or serious medical condition; people already subject to SNAP or TANF work requirements; people in drug or alcohol treatment; and people who are incarcerated or recently released. Under the federal law, someone denied Medicaid for not meeting the requirement isn't eligible for Marketplace tax credits either, so don't ignore a DSS notice.
More South Dakota Medicaid changes
Starting January 1, 2027, DSS is moving Medicaid Expansion enrollees to renewals every six months; American Indians and Alaska Natives are exempt. Beginning in October 2028, some expansion enrollees with income above 100% FPL will owe copayments, capped (for example, at no more than $35), and American Indians and Alaska Natives are exempt from those too. And since October 1, 2026, some noncitizens no longer qualify for Medicaid, including asylees, refugees, parolees (paroled for one year or more), and certain victims of abuse or trafficking. Most lawful permanent residents, Cuban and Haitian entrants, COFA migrants, and unborn children of ineligible noncitizens still qualify.
The November 2026 ballot question
The Legislature placed HJR 5001, a proposed amendment to the South Dakota Constitution, on the November 2026 general election ballot. The Attorney General's statement, filed May 18, 2026, explains that it would end expanded Medicaid coverage if federal funding for expansion drops below 90%. The statement also notes that current federal law funds 90% of expansion. Expansion coverage is in place today, and we won't guess at the vote. If your Medicaid ever ends, losing it generally opens a 60-day Special Enrollment Period for marketplace coverage.
How to apply: online through the SD BEES Customer Portal, with a paper application, or with help at your local DSS office. The DSS main line is 605-773-3165, and current members can reach the Medicaid Recipient Hotline at 800-597-1603.
Straight talk: South Dakota Medicaid is a state program, not something we sell. If it's your best option, we'll tell you exactly that and point you to the DSS application — no charge, no strings. And if your income sits above the Medicaid line, that's precisely where marketplace credits take over, and where a side-by-side comparison of every plan in your county matters most.
Income near the line? South Dakotans with seasonal work, farm or ranch income, gig income, or variable hours can move between Medicaid and the marketplace from year to year. In most cases, losing Medicaid eligibility opens a 60-day Special Enrollment Period for marketplace coverage. Don't guess at the boundary; a 10-minute call maps it.
South Dakota Marketplace Insurance: Plans & Prices for 2027
South Dakota's marketplace runs on HealthCare.gov, and every plan sold there is ACA-compliant: the 10 essential health benefits, no pre-existing condition exclusions, and preventive care at no cost. Carriers vary by county and change from year to year, so the only lineup that matters is the one for your ZIP code. We confirm which carriers actually offer 2027 plans in your county, and check them against your doctors and prescriptions, before recommending anything. (See our carrier partners.)
🪨 Bronze
Lowest premiums — they can be $0 after credits at lower incomes — with the highest deductibles. Exchange bronze plans now count as HSA-eligible, and the 2027 HSA limit is $4,500 for self-only coverage.
🪙 Silver
The sweet spot for most subsidy-eligible households. Under ~250% FPL, Cost-Sharing Reductions can cut a 2027 out-of-pocket maximum from $12,000 to as low as $4,000 for one person. CSRs come only with Silver.
🥇 Gold
Higher premium, lower out-of-pocket. The smart pick when you know care is coming — a planned procedure, a pregnancy, ongoing prescriptions.
🔹 Add-Ons
Dental & vision, accident, critical illness, and hospital indemnity plans stack alongside your ACA plan — often the difference between covered and comfortable.
Check the rate filings yourself: South Dakota's insurance regulator, the Division of Insurance in the Department of Labor and Regulation, offers a rate filing search and takes public comments on proposed increases at sdrateincreases@state.sd.us. Premiums and your credit change every year, so re-shop instead of auto-renewing.
Every ACA plan for 2027 caps in-network out-of-pocket costs at $12,000 for one person and $24,000 for a family. If you only need a stopgap, short-term health insurance in South Dakota is a different product: it isn't a Marketplace plan and doesn't come with tax credits. We also help South Dakotans with term life insurance and other life insurance — all through one licensed advisor.
One honest warning: a $0 premium is not $0 care. Free bronze plans carry real deductibles, and a 2027 marketplace plan can have an out-of-pocket maximum as high as $12,000 for one person. If your income is under ~250% FPL, a CSR Silver plan is often the far better deal than the "free" one. That's the judgment call a broker exists for.
Obamacare South Dakota Open Enrollment 2027: Key Dates
South Dakota uses the federal Marketplace, so the HealthCare.gov calendar applies: Open Enrollment runs November 1, 2026 – January 15, 2027. South Dakota isn't changing exchanges for 2027. DSS points people who don't qualify for Medicaid to the Marketplace at 1-800-318-2596 (TTY: 1-855-889-4325), and you can compare every state on our 2027 open enrollment deadlines by state page.
📅 November 1, 2026
Open enrollment opens on HealthCare.gov. Compare 2027 plans, premiums, and your new credit amount.
⏰ December 15, 2026
Last day to enroll or change plans for coverage that starts January 1, 2027, as long as you pay your first premium. This is the deadline that matters most.
🏁 January 15, 2027
Open enrollment ends. Enroll between December 16 and January 15 and coverage starts February 1, 2027 — a one-month gap.
🔄 After January 15
You'll need a qualifying life event (losing job coverage, losing Medicaid, moving, marriage, or a birth) to open a 60-day Special Enrollment Period.
Enrolling through FreedInsure takes about 15 minutes: (1) we project your 2027 income and calculate the exact credit, (2) we compare the plans in your county against your doctors and prescriptions, and (3) we submit the enrollment and stay on as your advisor all year. Same plans, same prices as going direct — plus a human who answers. Call (844) 788-3733 or check your South Dakota eligibility. For the national picture, read our Open Enrollment 2027 guide.
Straight talk on auto-renewal: if you do nothing, most enrollees are automatically re-enrolled in the same or a similar plan. But with credits smaller and premiums changing, last year's plan at last year's assumptions can be this year's overpay. Never let a plan auto-renew without a 15-minute re-shop — and do it before December 15 so any change starts January 1.
