Idaho Health Insurance Rates Up 12% for 2027: What Shoppers Must Know

The news: On October 6, 2026, the Idaho Department of Insurance finalized 2027 premium rates for individual and small-group health plans. Average premiums will rise about 12% in both the individual and small-group markets. If you buy your own health insurance in Idaho, your renewal letter — and the prices you see during open enrollment — will reflect the hike.

Open enrollment for coverage starting January 1, 2027 runs from October 15 through December 15, 2026, according to the department. That window is your once-a-year chance to shop the full market and lock in financial help. Here's what the increase means for you and the exact steps to keep your costs down.

The announcement, in brief

The Idaho Department of Insurance (DOI) approved final 2027 rates for every carrier selling individual and small-group plans in the state. The key numbers from the October 6 release:

• Individual market: average premiums up about 12% for 2027.
• Small-group market (plans bought through employers with 50 or fewer employees): average premiums also up about 12%.
• Each carrier's detailed justification for its rate change is posted publicly on the department's rate review page — worth a look if you want to see exactly why your carrier raised prices.

DOI Director Dean Cameron said Idaho's market "remains highly competitive and stable" and that the state's average increases are "still lower than many states." That context matters: 2027 rate filings nationally are running hot in many states, so Idaho's 12% is closer to middle of the pack than worst-case.

Why rates are rising

Insurers don't raise rates on a whim — state regulators have to approve them. According to the DOI, the drivers are the same forces pushing health costs up nationwide:

• Medical inflation: the underlying cost of hospital stays, procedures, and prescription drugs keeps climbing year after year.
• National pressures: broader cost trends that state regulators describe as affecting insurers across the country, not just in Idaho.

There is also a cushion worth knowing about: Idaho's 1332 State Innovation Reinsurance Waiver. The waiver helps insurers cover very expensive medical claims, which pulls premiums down for everyone. According to the DOI, the waiver held 2025 premiums about 20% lower than they would have been without it, about 18% lower in 2026, and is expected to reduce 2027 premiums by about 16%. Without it, the 2027 increase would have been substantially steeper.

What a 12% increase means for you

"Average" hides a lot of variation. Your personal increase depends on your carrier, your plan, your age, and where you live in Idaho — some shoppers will see less than 12%, some more. Roughly speaking, a benchmark Silver plan that cost $550/month in 2026 would run in the neighborhood of $615/month in 2027 — around $65 more per month, or about $780 more per year. That's an approximation, not your actual bill: check your carrier's renewal notice and the exchange prices when they go live.

What matters most is that you do not have to accept your renewal price. The average hides cheaper options. The DOI notes that Idaho's marketplace, Your Health Idaho, lists more than 143 medical plans and 22 dental plans — with that many choices, re-shopping is one of the most effective ways to dodge the full 12%.

Open enrollment: dates and tax credits

• Enrollment window: October 15 – December 15, 2026, for coverage starting January 1, 2027.
• Where to shop: Idaho's own marketplace, Your Health Idaho (not HealthCare.gov).
• Financial help: premium tax credits and cost-sharing savings that lower monthly premiums and out-of-pocket costs are available only through Your Health Idaho — you cannot get them buying the same plan directly from an insurer. Most marketplace shoppers nationwide qualify for some level of help.
• Free guidance: licensed, certified agents on the exchange can walk you through options, and the department lists a helpline at 855-944-3246.

One caveat for freelancers and the self-employed: subsidy amounts are based on your estimated annual income, so update your income projection when you apply. Our guide to health insurance for the self-employed walks through metal tiers and subsidy mechanics in detail.

What to do now: 6 steps to save

1. Don't auto-renew. Your carrier will renew you at the 2027 price if you do nothing. Log in to Your Health Idaho when the window opens and compare.
2. Re-check your subsidy. If your income changed since last year, your premium tax credit may have changed too — in either direction. Update it before you pick a plan.
3. Compare across all 143+ plans. Cheaper premiums, different networks, different drug formularies. Sort by total cost (premium + expected out-of-pocket), not premium alone.
4. Verify your doctors and drugs. The cheapest plan with your doctors out-of-network is the most expensive plan of all. Confirm networks and formularies before enrolling.
5. Look at Silver if your income is modest. Silver plans are the only tier where extra cost-sharing reductions apply — they can make Silver cheaper in total cost than Bronze.
6. Enroll before December 15. Miss the deadline and you wait a year for 2027 coverage unless you have a qualifying life event (job loss, move, marriage, new baby).
