Self-Employed Health Insurance in Montana
Working for yourself in Montana means you pick your own health plan, and the right one depends on your income, your health and a few rules that only apply in Montana. Individual premiums in Montana are set to rise 22.6% to 23.3% on average for 2027, and with the enhanced tax credits gone, anyone above the subsidy line pays the full increase.
Private health insurance in Montana
Most people I help in Montana end up on a private plan, not a Marketplace plan. Private, medically underwritten health insurance is priced on your age, zip code and health instead of your income, so a strong year never raises your premium and there is no tax credit to pay back in April.
Why people leave the Marketplace
- Premiums keep climbing. Montana Marketplace premiums are rising 22.6% to 23.3% on average for 2027.
- The subsidy cliff. Above 400 percent of the poverty level ($63,840 for one person, $132,000 for a family of four) you pay full price.
- Surprise tax bills. Underestimate your income and you repay the tax credit in April.
- Narrow networks. Many plans are local HMOs or EPOs that need referrals and cover little outside the area.
- High out-of-pocket costs. 2027 out-of-pocket maximums reach $12,000 per person and $24,000 per family.
- One window a year. Outside open enrollment you need a qualifying life event to enroll or switch.
What a private plan does differently
- Start any month. If approved, coverage can begin the first of next month, with no wait for open enrollment.
- Networks that travel. Many private plans use national PPO networks, which can give you in-network doctors outside Montana too. Networks vary by plan.
- Can cost less than full-price Marketplace plans for some healthy applicants above the subsidy line.
- Accident coverage the Marketplace does not offer. A private plan can be paired with accident coverage, a separate policy. What it includes varies by plan.
- Approval is based on health. You answer health questions, and acceptance is not guaranteed.
With a significant health condition, or income low enough for a large tax credit, a Marketplace plan can be the better fit, and I will tell you if it is. Either way you see both side by side.
Private plans are not ACA Marketplace plans. Benefits, exclusions and pre-existing condition rules differ by plan and by state, so review the plan details before you enroll.

Who works for themselves in Montana
Nearly every Montana business is small: the SBA Office of Advocacy'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.
How Montana taxes self-employed health premiums
Montana has an income tax, and since tax year 2024 its return starts from federal taxable income under SB 399, so the federal self-employed health insurance deduction and HSA deduction flow through to the state return. The top rate is 5.65 percent for 2026 and drops to 5.4 percent in 2027. Montana adds its own break: deposits to a Montana medical care savings account, up to $4,600 for 2025, reduce state taxable income, and no high-deductible plan is required. General information, not tax advice — confirm with your CPA based on your specific entity structure.
Montana options beyond the Marketplace basics
Montana's reinsurance program runs under a federal waiver approved for 2025 through 2029, and Treasury set its federal pass-through funding at about $35.9 million for 2026. That money reimburses insurers for some large claims, which matters most to self-employed buyers who pay full price. Montana's medical care savings account is a second, state-only tool: any resident 18 or older can open one at a bank or credit union, even alongside a federal HSA, for eligible medical costs. Self-funded multiple employer welfare arrangements must hold a certificate of authority under MCA 33-35-201.
Montana at a glance for people who work for themselves
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 tradespeople should base their Marketplace income estimate on the full year, not a busy summer month.
Other Montana rules to know
- Leaving a small employer: 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.
- Short-term plans: Montana does not limit the duration of short-term plans in its own law, so federal rules govern, and federal agencies are not prioritizing enforcement of the four-month federal limit.
- Where to enroll: Montana uses HealthCare.gov. Open enrollment for 2027 coverage runs November 1, 2026 to January 15, 2027. Private, medically underwritten plans can start the first of any month if approved.
- 2027 rates: individual plans 22.6% to 23.3% on average, small-group plans about 18%. See the Montana 2027 rate page.
Private plan or Marketplace
Above 400 percent of the poverty level, a Marketplace plan costs full price. A healthy self-employed buyer in that range may pay less with a private, medically underwritten PPO priced on health rather than income, and if approved, it can start the first of any month. With a health condition, or with income low enough to qualify for a credit, the Marketplace is usually the better choice because approval is guaranteed.
Estimating income when it changes every month
The Marketplace credit is based on this year's projected net income from Schedule C or your K-1, not gross revenue. Estimate conservatively, update it when a big contract lands, and remember that above the line you repay the entire advance credit.
An HSA as a second retirement account
For 2027 every bronze and catastrophic plan is HSA-eligible, and the contribution limits are $4,500 for self-only coverage and $9,000 for family coverage, plus $1,000 at 55 or older.
For 2027 the Marketplace credit stops at 400 percent of the poverty level: $63,840 for one person, $86,560 for two and $132,000 for a family of four. The out-of-pocket maximum for 2027 Marketplace plans is $12,000 for one person and $24,000 for a family. The full guide covers the rest.
