Self-employed health insurance in Montana: a small market and how to work it (2026)

Sam Jaber, Licensed Health Insurance Advisor · Updated September 2026

If you are self-employed in Montana, your realistic choices are Medicaid in a low-income year, a HealthCare.gov plan with a federal tax credit, the same plan at full price, or coverage sold off the marketplace that asks health questions. Keeping a former employer's plan is possible after some job changes, but Montana's options there may be narrower than you expect.

The defining feature of the Montana market is its size. Only three private insurers sell plans on the marketplace for 2026, and one of them is leaving Montana's individual market after 2026, so the choice you get is less about hunting through dozens of plans and more about knowing which few fit you.

What working for yourself looks like here

A ranch hand turned contractor, a guide who runs a seasonal outfit, a Bozeman consultant: whatever the business, the pattern is the same. You pay the whole premium, and you estimate an income that can swing sharply between seasons. That estimate decides which program fits, so it deserves more care than a quick guess.

Montana uses HealthCare.gov rather than a state-run exchange. For 2026 coverage, open enrollment ran from November 1, 2025 to January 15, 2026. Outside open enrollment you generally need a qualifying life event, such as losing other coverage, to sign up.

Medicaid in a lean season

Montana expanded Medicaid effective 2016 and reauthorized the program, with changes, in 2019. Adults can qualify with income up to 138% of the federal poverty level.

For seasonal and early-stage businesses, that matters. A year that comes in thin does not have to mean going without coverage. One catch is that Montana began requiring most expansion adults ages 19 to 64 to document at least 80 hours a month of work or other qualifying activity on July 1, 2026, ahead of the federal deadline of January 1, 2027. Another is that Medicaid counts self-employment income by its own method, which may not match your tax return line for line. If you are anywhere near 138%, ask how your earnings will be treated before deciding you need a private plan, and report changes when income rises.

Marketplace plans with federal help

Above the Medicaid line, the federal premium tax credit is where most self-employed Montanans find their best value. It is based on household size, projected income, and the benchmark plan for your area, and you can apply it to your monthly bill as you go.

Because it rests on a forecast, the credit is settled when you file. Earn more than you projected and part of it may come back out of your refund. The enhanced federal credits of the past few years ended after 2025, so there is again an income point where help stops outright. If your year is hard to predict, spend a few minutes on our breakdown of the subsidy cliff for variable earners before you settle on a figure.

Marketplace plans cannot turn you down over your health or charge you more for a condition, and they cover a standard set of benefits. In a small market, that guarantee is worth weighing first if you have ongoing care needs.

Full price, with reinsurance behind the rates

Earn above the federal credit range and you can still buy any marketplace plan, keeping all the same protections. The bill is simply yours in full.

Montana does work to hold that bill down. The state runs a reinsurance program under a federally approved Section 1332 waiver. Its most recent extension, granted on September 17, 2024, runs from January 1, 2025 through December 31, 2029. Reinsurance pays a share of insurers' largest claims, which allows lower rates to be filed. The approved term covers several years rather than one, which gives full-price buyers a steadier backdrop than a program renewed annually.

Some healthy households above the credit range also look at underwritten coverage sold off the marketplace. That coverage asks health questions and can decline an applicant, exclude conditions, or price on the answers, and its benefits follow different rules. Our explainer on underwritten health coverage and its trade-offs is the right starting point. Short-term medical plans fall in the same group, and federal rules on how long they may run have changed more than once recently, so confirm the term and renewal rules on any plan before relying on it.

Leaving a job: fewer bridges than you might expect

Federal COBRA applies when your former employer had 20 or more workers, and it lets you keep that group plan for a period if you pay the full premium.

Many states add their own continuation law for smaller employers. Reporting indicates Montana does not have one. If that holds for your situation, leaving a small Montana employer may mean your group coverage simply ends, with no state-law option to continue it. Confirm with the employer or the Montana Commissioner of Securities and Insurance before you count on anything, and have a marketplace plan lined up in case. Losing job-based coverage usually opens a special enrollment period on HealthCare.gov, so you do not have to wait for the fall. Our guide on bridging the gap between jobs covers the timing.

Montana's 2026 numbers

The benchmark plan is the second-lowest-cost silver plan in an area, and federal help is calculated from it. For a 40-year-old in Montana, the average benchmark premium was $692 a month in 2026, compared with $554 in 2025. That is a rise of about 24.9%.

Enrollment moved the other way. Montana's marketplace enrollment for the 2026 season was reported down about 5%.

Treat these as statewide context. The price you would be quoted depends on your age, county, household and income, and 2027 rates are approved separately.

Deciding in Montana

Place your likely income first, then check which of the three insurers' plans in your county cover your doctors and medications.

• Base your estimate on a full year, not just your busy season.
• Check networks before price. In a three-insurer market, the plan that includes your doctor may be the only one worth considering.
• If you are leaving a small employer, ask right away whether any continuation is offered, and do not assume it is.
• Revisit each fall. Rates and insurer participation can change from one year to the next.

On taxes, the federal self-employed health insurance deduction is the main one for owners; our page on writing off your own health premiums explains the rules. Your preparer can tell you how it carries onto your Montana return.
