South Dakota's 10 percent is finalized and below the national average, with small-group plans up about 8.3 percent. Three insurers remain, two of them tied to the state's health systems. More detail is on the South Dakota 2027 premium increase page.
For South Dakota households buying 2027 coverage, the Marketplace premium tax credit stops at 400% of the federal poverty level: $63,840 for one person, $86,560 for two, $109,280 for three and $132,000 for four. The repayment caps were removed starting with tax year 2026, so any excess advance credit is repaid in full on Form 8962. General information, not tax advice — confirm with your CPA based on your specific entity structure.
Who this year's window matters for in South Dakota
In South Dakota, choosing a 2027 plan often means choosing a health system: two of the three insurers are tied to the state's major systems, so your network decides where you get care in Sioux Falls, Rapid City and beyond. Finalized rates rise about 10 percent, below the national average.
Self-employed work that is common in South Dakota, and the people I most often help there: corn, soybean and cattle operations, custom harvesters and ag contractors, owner-operator truck drivers on I-29 and I-90, construction trades, Black Hills tourism and outfitting businesses, and real estate agents.
Before you renew in South Dakota
South Dakotans near the Minnesota, Iowa or Nebraska lines who use clinics across the border should look those clinics up in the plan directory before renewing. Farm and ranch families should build the 2027 estimate from a realistic year, since the subsidy line decides whether any help applies at all. Sioux Falls has the most plan choice; western South Dakota has less.
Should you renew, switch, or look at private?
Auto-renew risk
Do nothing and HealthCare.gov re-enrolls you at the new 2027 price, 10.1% to 10.4% higher on average in South Dakota.
Healthy, income above the line
Price a private plan in South Dakota too. If approved, it can start the first of any month, with no wait for South Dakota's window.
Health conditions or subsidy-eligible income
Use the Marketplace. HealthCare.gov plans can't decline you or charge more for your health.
Checklist before you pick a plan
- Your South Dakota renewal notice
- The new 2027 premium and deductible
- Doctors and prescriptions still in network, including any care in Sioux Falls or Rapid City
- Your 2027 income estimate
Missed it?
After South Dakota's window closes, a Marketplace plan needs a special enrollment event: losing other coverage, a move, marriage or a baby, generally within 60 days, through HealthCare.gov. Check with Can I enroll now? or the missed open enrollment guide.
Leaving a job in South Dakota? If you leave an employer with fewer than 20 employees, South Dakota law lets you continue the group plan for 18 months at no more than 102 percent of the group rate, with up to 36 months for some family members, such as after a divorce or the employee's death.
Short-term plans, if you only need a bridge: South Dakota's insurance rules allow short-term plans with an initial term under 12 months and up to 36 months in total, while the federal four-month limit remains on the books but is not being prioritized for enforcement. They are not Marketplace coverage.
In South Dakota, a private, medically underwritten plan needs no event. If approved, it starts the first of a month; approval is not guaranteed.
