Short-Term Health Insurance in South Dakota: 2027 Rules
A short-term health plan in South Dakota is a temporary policy meant to fill a gap of weeks or a few months, not a full replacement for major medical coverage. It can exclude pre-existing conditions, cap what it pays and decline applicants, and South Dakota adds its own rules on top of the federal limits. With South Dakota Marketplace premiums rising 10.1% to 10.4% on average for 2027, more people are looking at short-term plans, so it pays to know what they leave out. I don't sell short-term plans; this page explains how they work in South Dakota and the year-round options I do offer.
Private health insurance in South Dakota
Most people I help in South Dakota end up on a private plan, not a Marketplace plan. Private, medically underwritten health insurance is priced on your age, zip code and health instead of your income, so a strong year never raises your premium and there is no tax credit to pay back in April.
Why people leave the Marketplace
- Premiums keep climbing. South Dakota Marketplace premiums are rising 10.1% to 10.4% on average for 2027.
- The subsidy cliff. Above 400 percent of the poverty level ($63,840 for one person, $132,000 for a family of four) you pay full price.
- Surprise tax bills. Underestimate your income and you repay the tax credit in April.
- Narrow networks. Many plans are local HMOs or EPOs that need referrals and cover little outside the area.
- High out-of-pocket costs. 2027 out-of-pocket maximums reach $12,000 per person and $24,000 per family.
- One window a year. Outside open enrollment you need a qualifying life event to enroll or switch.
What a private plan does differently
- Start any month. If approved, coverage can begin the first of next month, with no wait for open enrollment.
- Networks that travel. Many private plans use national PPO networks, which can give you in-network doctors outside South Dakota too. Networks vary by plan.
- Can cost less than full-price Marketplace plans for some healthy applicants above the subsidy line.
- Accident coverage the Marketplace does not offer. A private plan can be paired with accident coverage, a separate policy. What it includes varies by plan.
- Approval is based on health. You answer health questions, and acceptance is not guaranteed.
With a significant health condition, or income low enough for a large tax credit, a Marketplace plan can be the better fit, and I will tell you if it is. Either way you see both side by side.
Private plans are not ACA Marketplace plans. Benefits, exclusions and pre-existing condition rules differ by plan and by state, so review the plan details before you enroll.

Short-term plan rules in South Dakota
South Dakota allows short-term coverage, overseen by the Division of Insurance within the Department of Labor and Regulation. According to healthinsurance.org, administrative rule 20:06:10:08.03 requires terms of less than 12 months and requires insurers to state plainly that the plan does not cover pre-existing conditions and is not minimum essential coverage under the ACA. A separate rule, 20:06:39:34.02, addresses renewability. Total length varies by insurer: some cap a policy at six or twelve months, while at least one allows three back-to-back 364-day terms on a single application. At least three insurers were selling here in 2026. Because federal officials paused enforcement of their 2024 four-month limit in August 2025, the state rules are what currently shape plan length.
When a short-term plan fits in South Dakota, and what to use instead
In South Dakota the people asking about short-term plans are often between a harvest season and a winter job, or working summer tourism in the Black Hills before heading back to school or a permanent position. A short-term policy can cover an unexpected accident during that stretch, but it carries the state's required warning: no coverage for pre-existing conditions and no ACA status, so subsidies don't apply. South Dakotans enroll in Marketplace coverage through HealthCare.gov, and losing other coverage triggers a 60-day special enrollment period. Ranchers and self-employed residents who want ongoing protection can apply for a medically underwritten private plan at any point in the year, with a start date on the first of a month if approved. Frank can explain the tradeoffs.
The South Dakota individual market
South Dakota buyers shop on HealthCare.gov, where premium tax credits are based on the household income you expect for the year. The enhanced federal credits expired at the end of 2025, and starting with the 2026 tax year there is no cap on paying back excess advance credits, so a South Dakota tradesperson whose income jumps after a strong building season can owe the full difference at tax time. Updating your income estimate as soon as work picks up is the simplest protection. If you leave an employer with fewer than 20 workers, the state's 18-month continuation right keeps your group plan at up to 102 percent of the group rate, which can bridge you to a new job or the next open enrollment. Short-term plans can run under 12 months at a time and up to 36 months in total under state rules, but they are not ACA plans and can exclude preexisting conditions. South Dakota does not run a state premium subsidy or reinsurance program.
Other South Dakota rules to know
- Leaving a small employer: 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: 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.
- Where to enroll: South Dakota uses HealthCare.gov. Open enrollment for 2027 coverage runs November 1, 2026 to January 15, 2027. Private, medically underwritten plans can start the first of any month if approved.
- 2027 rates: individual plans 10.1% to 10.4% on average, small-group plans about 8.3%. See the South Dakota 2027 rate page.
What a short-term plan is
Short-term limited-duration insurance is temporary coverage outside the ACA rules. It can ask health questions, turn applicants down, exclude conditions you already have and leave out benefits such as maternity care, mental health care or prescriptions. It is not Marketplace coverage, so no subsidy applies to it.
Why the time limit matters
A 2024 federal rule caps short-term plans at three months, or four with renewals. In August 2025 federal regulators said they would not prioritize enforcing that cap, so the real limit now depends on your state, from a few months to as long as three years. However long it lasts, when the plan ends you are not guaranteed a new one, and losing a short-term plan does not open a Marketplace enrollment window.
The two options that last all year
A Marketplace plan accepts everyone during open enrollment or within 60 days of losing other coverage. A medically underwritten private plan is year-round coverage priced on age, ZIP code and health; it is not a Marketplace plan, approval depends on your health answers, benefits vary by plan, and if approved it can start the first of a month. For most people who need more than a short bridge, one of these two is the better fit.
For 2027 the Marketplace credit stops at 400 percent of the poverty level: $63,840 for one person, $86,560 for two and $132,000 for a family of four. The out-of-pocket maximum for 2027 Marketplace plans is $12,000 for one person and $24,000 for a family. The full guide covers the rest.
