Montana 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 Montana, 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
Montana's average 2027 rate change is 22.6% to 23.3% (finalized). The details are on the Montana 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.
Montana this year
Montana's finalized 2027 increase lands near 23 percent, one of the largest among my states, and only two insurers filed, so in many counties the decision comes down to two networks. Distance shapes everything: from a ranch on the plains or a home in the Flathead Valley, an in-network hospital may sit an hour or more down the road. The state's reinsurance program, approved through 2029, helps but did not stop a big jump. Past 60, age pricing alone pushes premiums high, and if pension or account withdrawals put you past the subsidy line, you cover the full increase.
Leaving a job in Montana? Montana has no general continuation law for people who leave a small employer; its law only lets a worker whose hours drop below the plan's minimum keep group coverage for up to one year, with the employer's consent and at the group rate. 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
Montana's continuation law only helps workers whose hours drop, not people leaving a small employer, so a small-business retiree should line up a new plan immediately. Before choosing between the two networks, confirm which hospital in Billings, Missoula, Bozeman or Great Falls you would actually use, and whether it is in network. That matters more here than a modest premium difference.
Your checklist
- Which accounts you will draw from in 2027
- Networks where you live, in and outside Montana
- 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 Montana?
January 15, 2027 on HealthCare.gov. Choose by December 15, 2026 for coverage that starts January 1; plans picked after that start February 1.
With only two insurers in Montana, does it make sense for us to look outside the Marketplace?
For healthy early retirees above the subsidy line, it can. Medically underwritten private plans set prices from your health, age and ZIP code, not income, and if approved can start the first of any month. They are not Marketplace plans, acceptance hinges on your health history, and covered services differ by plan.
Can I get a private plan in Montana 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.
