Idaho Health Insurance in 2026

Idaho's Your Health Idaho has the earliest Open Enrollment deadline in the country — it closes December 15, a full month before most states. Miss it and you'll need a qualifying life event to enroll.

Where you enroll. Idaho runs its own marketplace, Your Health Idaho, rather than using HealthCare.gov. That means the state sets its own Open Enrollment deadline (December 15 for 2027 coverage) and can add its own programs on top of the federal subsidies.

Medicaid vs. subsidies. Because Idaho expanded Medicaid, adults up to about 138% of the federal poverty level generally qualify for Idaho Medicaid at little or no cost. Above that line, you shop subsidized Marketplace plans — the calculator above shows which side of the line you're on.

The biggest lever on your Idaho premium is the ACA premium tax credit. It caps what you pay for a benchmark silver plan at a percentage of your income — the lower your income, the larger the credit — and the government pays the rest directly to your insurer.

If your income is under about 250% of the poverty level, look at Silver plans first: they come with cost-sharing reductions that shrink your deductible and copays, which no other tier gets. Our guide to Bronze vs. Silver vs. Gold walks through it.

One important change for 2026: the enhanced pandemic-era subsidies expired unless renewed, so the “400% cliff” may return for higher earners. That makes comparing plans with a licensed Idaho agent more valuable than ever. Prefer to read up first? Start with our ACA health insurance overview or the subsidy calculator.
