How to Find the Cheapest Health Insurance in South Dakota
Follow these steps to find affordable health insurance in South Dakota:
- 1
Determine coverage plan needs and affordability
Your coverage plan type and tier will differ widely depending on your personal health circumstances and income. Calculate how much income you can set aside for monthly premiums, considering your current health and risk for injury or disease based on location, age and lifestyle.
- 2
Find out your subsidy eligibility
People earning between $14,580 and $54,000 annually may qualify for premium tax credits, reducing costs by 40% to 100%. Those with incomes below 250% of the Federal Poverty Level ($36,450) can access cost-sharing reductions, decreasing out-of-pocket expenses up to 73%.
- 3
Consider federal programs for eligible age groups
If you're of suitable age, explore Medicare Advantage plans and Medicare Supplement plans. These plans may offer more affordable and flexible alternatives to traditional plans.
- 4
Review prescription formularies
Check insurers' prescription coverage for medications you regularly take. Choosing plans with lower-tier placements and reduced copays for your medications can optimize savings and ensure consistent and affordable access to necessary prescriptions, saving you hundreds of dollars each year.
- 5
Compare plans during Open Enrollment
Open Enrollment is from November 1 to January 15, but you may also qualify for Special Enrollment if you've lost your job, divorced or had a child. Consider the types of coverage available, customer ratings, associated costs and the plan's compatibility with your medical providers.
MONEYGEEK TIP: MAKE SURE TO APPLY PROMPTLY
To avoid technical issues, apply for coverage at least five days before the enrollment deadline. Prepare your income verification, Social Security numbers and immigration documents to ensure a smooth application process.

How We Decided the Cheapest Health Insurance Companies in South Dakota
MoneyGeek obtained data directly from the Centers for Medicare and Medicaid Services (CMS) on available health insurance plans in South Dakota based on consumers aged 18, 26, 40, 50 and 60.
We considered the cheapest overall to be those with the lowest monthly premium costs for 40-year-olds, as most in the state are near this age demographic, and for simplicity. However, cheaper plans tend to have higher out-of-pocket maximums and deductibles, meaning you may pay more if you receive care.
