Open enrollment for 2027 coverage runs October 15, 2026 through December 15, 2026. The closing date is not necessarily the deadline for January 1 coverage. Ask Your Health Idaho about the required plan-selection and payment dates.

State average premiums and modeled costs by age
These 2026 figures compare one adult before premium tax credits. KFF weights each county's second-lowest-cost silver (benchmark) and lowest-cost bronze premiums by Marketplace plan selections. They are state averages, not a quote or the price of one plan available throughout Idaho. Your location, plan and household details affect your premium.
| Age | Benchmark silver average | Avg. lowest bronze |
|---|---|---|
| 21 | $383 | $271 |
| 30 | $435 | $307 |
| 40 | $490 | $346 |
| 50 | $685 | $483 |
| 60 | $1,041 | $735 |
| 64 | $1,150 | $812 |
Scaled from the age-40 average with the federal default age curve, which lets insurers charge a 64-year-old up to 3× what a 21-year-old pays. Amounts at ages other than 40 are modeled from the state averages. Excludes tobacco surcharges.
The Idaho benchmark rose 12% for 2026, less than the 26% national increase, leaving it 22% below the U.S. average for a 40-year-old.

- Where and when. Idaho runs its own marketplace, Your Health Idaho, so you apply there rather than at HealthCare.gov. Open enrollment for 2027 coverage runs October 15, 2026 through December 15, 2026. The closing date is not necessarily the deadline for January 1 coverage. Ask Your Health Idaho about the required plan-selection and payment dates.
- Choice of insurers. 8 insurers sell Marketplace plans in Idaho for 2026, the same number as in 2025. Not every insurer sells in every county, so your choices depend on where you live. 120,426 people picked a Marketplace plan here for 2026, up 3% from 2025, one of 10 states (counting DC) where sign-ups rose even as the enhanced federal credits ran out.
- Average premiums for selected plans. Plans selected during open enrollment had an average monthly premium of $202 after advance premium tax credits for 2026, up 57% from the $129 average for 2025 (U.S. average: $178). Before credits, selected plans averaged $509. These averages include people without tax credits and compare different mixes of people and plans; they aren't records of premiums actually paid or a quote for your household.
- Medicaid. Idaho expanded Medicaid in January 2020, after voters approved it in November 2018. Adults with income up to 138% of the federal poverty level can generally get Medicaid instead of a Marketplace plan. A state "trigger" law would end the expansion or force cost cuts if federal funding for it is reduced.
- Going uninsured. Idaho doesn't charge a penalty for going without coverage, and the federal penalty ended after 2018. In 2024, 9% of residents had no health insurance (U.S.: 8.2%), and 7.6% bought their own coverage.
Medicaid income limits above describe the adult categories shown. Pregnancy, disability, age, household circumstances and other eligibility rules can create different pathways. Apply even if your state has not expanded Medicaid; the application checks whether you qualify under your state's rules.
Subsidies in 2026
The enhanced premium tax credits of 2021–2025 expired. Under the 2026 federal rules, household incomes generally between 100% and 400% of the federal poverty level may qualify, subject to the other eligibility conditions; income alone does not establish eligibility. The expected contribution toward the benchmark plan ranges from about 2.1% to 9.96% of income, and above 400% there is no federal credit. An affordable employer offer that meets minimum value, or eligibility for certain public coverage, can affect credits even if you do not enroll in the employer plan. Confirm your eligibility and price with the official marketplace.
Use expected household income for the year you want coverage, including income before and after a job change, rather than only your new job's annual salary. These are 2026 subsidy and premium figures; select the appropriate coverage year at Your Health Idaho when applying. Eligibility guidance checked October 21, 2026.
Moving outside open enrollment
A move to a new ZIP code or county may create a Special Enrollment Period if it changes the plans available to you. Moving only for a vacation or medical treatment does not qualify.
Generally, a moving SEP requires qualifying coverage for at least one day in the 60 days before the move, and enrollment within 60 days after it. Exceptions include a move from abroad or a U.S. territory. Keep proof of your old coverage, move date and new address. The marketplace decides eligibility and when coverage starts; do not cancel existing coverage until the replacement start date is confirmed.
Check whether you may qualify at HealthCare.gov. For Your Health Idaho enrollment, ask the official marketplace about your move.
