South Dakota Open Enrollment 2027 for Early Retirees
Last updated November 3, 2026 · By Frank Caballero, licensed health insurance broker
Short answer
For early retirees under 65 in South Dakota, open enrollment for 2027 coverage runs November 1, 2026 to January 15, 2027 on HealthCare.gov, and December 15 is the date to choose by for a January 1 start. A private, medically underwritten plan does not depend on the window: if approved, it can start the first of any month, including the month after your last day of work.
What 2027 looks like for you
South Dakota's average 2027 rate change is 10.1% to 10.4% (finalized). The details are on the South Dakota 2027 premium increase page.
For 2027 the subsidy line is $63,840 for one person and $86,560 for a couple. Pension income and withdrawals from pre-tax retirement accounts generally count toward it, and Marketplace prices for the oldest adults can run up to three times those for a 21-year-old, so the early sixties are the costliest years to land just over the line. General information, not tax advice — confirm with your CPA based on your specific entity structure.
South Dakota this year
South Dakota's finalized 2027 increase is about 10 percent, below the national average, which helps early retirees paying full price. Three insurers filed, and two are tied to the state's major health systems, so picking a plan here often means picking where you get care in Sioux Falls, Rapid City and the towns between them. Once you reach your sixties, your age is still the largest piece of the premium. Retired farmers and ranchers with uneven income should treat the subsidy line carefully, since one strong year of sales can decide whether any Marketplace help applies on HealthCare.gov.
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. Federal COBRA normally lasts 18 months, so it rarely covers the whole stretch to 65 on its own.
One thing to do before you choose
South Dakota lets people leaving an employer under 20 employees continue the group plan for 18 months at no more than 102 percent of the group rate. Time it well and those months can shrink the gap before 65 considerably. Either way, confirm which health system your doctors belong to before you pick a 2027 plan.
Your checklist

- Networks where you live, in and outside South Dakota
- Your prescriptions on each drug list
- The month you turn 65
Private plan or Marketplace?
Private plan
Healthy, with withdrawals above the line: priced on age, ZIP code and health, not your retirement income. Approval depends on health answers; not an ACA Marketplace plan.
Marketplace
An ongoing condition, or income you can keep under the line: HealthCare.gov must accept you, and near 65 the subsidy can be large.

Questions
When is the 2027 open enrollment deadline in South Dakota?
January 15, 2027 on HealthCare.gov. Choose by December 15, 2026 for coverage that starts January 1; plans picked after that start February 1.
Our doctors are in Rapid City, but my spouse sees a specialist in Sioux Falls. Can one plan cover both?
Possibly, but check carefully. Networks are built around the Sioux Falls and Rapid City health systems, and two of the three insurers are tied to them. A plan centered on one system may not include the other, so I verify both doctors before comparing prices.
Can I get a private plan in South Dakota after open enrollment closes?
Yes. You can apply in any month and, if approved, a private plan can start the first of a month; the insurer can decline based on health answers.
