Montana at a glance

What a quote takes

1. Book a 15-minute call by phone or video, in English or Spanish. There is no fee.
2. Have ready: your Montana ZIP code, everyone's ages, your doctors (in Billings, Missoula or elsewhere), prescriptions, a rough income estimate for the HealthCare.gov side and your health history for the private side.
3. Frank prices private plans from your health answers and Marketplace plans on HealthCare.gov from your income, and checks each network for your doctors.
4. Next, a private application goes to the insurer for an underwriting decision; if approved, coverage can start the first of the next month. HealthCare.gov enrollment happens in open enrollment or a special enrollment period, with Frank's help.

Private plan vs. the Marketplace in Montana

Short-term plans are sold in Montana as a bridge of a few months under federal rules and exclude pre-existing conditions. The private PPO plans we quote are medically underwritten and year-round.

Montana rules that shape a quote

Montana buyers use HealthCare.gov, and open enrollment for 2027 coverage runs November 1, 2026 to January 15, 2027, with coverage starting January 1 for plans picked by December 15. Montana runs a state reinsurance program under a federal waiver approved for 2025 through 2029, which reimburses insurers for some high-cost claims and is designed to keep individual premiums lower than they would otherwise be. Montana has no general continuation law for small employers, so a tradesperson leaving a shop too small for federal COBRA usually needs new coverage right away; losing job-based coverage opens a special enrollment period on the Marketplace. Montana sets no short-term duration limit of its own, so federal rules apply, and short-term plans are not ACA coverage. Because Montana's building season is short, self-employed workers should base their Marketplace income estimate on the full year, not a busy summer month.

Who usually starts with which

Common self-employed work in Montana: Ranching families, outfitters and guides working a short season, construction trades in Bozeman and the Flathead, oil and gas contractors in the Bakken counties, remote tech workers who moved in, and real estate agents.

Nearly every Montana business is small: the SBA's 2025 profile puts the count at 141,011, or 99.2 percent of firms, and about 106,000 have no payroll at all. Real estate and rental is the largest one-person category at nearly 16,000, followed by construction, professional services, and repair and personal services, while arts, recreation and entertainment add about 6,900 more. Small firms employ 66.3 percent of Montana's workers, about two of every three, and roughly 47,000 small businesses are in rural areas. Most of those owners arrange their own health coverage.

Montana's 73,255 HealthCare.gov plan selections for 2026 were about 5 percent below the 77,221 recorded for 2025, the CMS state-level public use file shows. Roughly 77.7 percent of enrollees, or 56,892 people, received an advance premium tax credit. The other 22 percent or so, about 16,400 people, paid full price, close to double the roughly 8,500 who did so a year earlier, when the enhanced credits still applied. That full-price share is higher than in Nebraska, South Dakota or Wyoming. About 44 percent of Montana enrollees used an agent or broker, and new sign-ups fell to 10,443 from 15,404.

Business owners with employees

Final 2027 small-group rates in Montana rise about 18 percent on average, and four insurers have small-group filings after one that had planned to leave the market decided to stay. Montana's small employer law, MCA 33-22-1803, defines a small employer as one that employed two to 50 eligible employees during the preceding calendar year and at least two on the first day of the plan year, with affiliated companies counted as one. A business that was not open all of the prior year is judged on the staff it reasonably expects to employ this year.

Leaving a job or group plan

For Montanans, the move off COBRA or a small employer's plan runs through HealthCare.gov. Losing job-based coverage opens a 60-day special enrollment window, and you can apply up to 60 days early; choose a plan by month's end and coverage can start the first of the next month. Since most small-employer plans in Montana end with the job, line up the new plan before your last day.

If you are self-employed in Montana, premiums for you and your family are often deductible on your federal return, whichever kind of plan you choose. General information, not tax advice — confirm with your CPA based on your specific entity structure.
