What a tax credit does (in Yellowstone County, the state's most populous county)
| Household | % of poverty level | Estimated tax credit | Cheapest Bronze, full → after credit |
|---|---|---|---|
| A single 40-year-old earning $40,000 | 255% | $274/mo | $354 → $79 |
| A family of four (parents 40 and 38, two kids) earning $85,000 | 264% | $1,152/mo | $1,122 → $0 |
2025 federal poverty guidelines apply to 2026 coverage; the enhanced credits of 2021–2025 expired, so the 400% cutoff is back (for one person that is $62,600 a year, for four $128,600). The Marketplace sets the final credit.

A family of four (parents 40 and 38 with two children) is typically quoted $497 to $978 a month in Montana. Private plans are not ACA plans: no tax credit, health questions on the application, and pre-existing conditions can raise the price or be excluded. Deductibles are usually lower than the cheapest Marketplace tiers and you can enroll any month of the year.

Questions people ask
How much is health insurance in Montana per month?
For a 40-year-old paying full price in 2026, Marketplace Bronze plans typically run $505 to $621 a month across Montana counties, Silver $708 to $832, and the silver benchmark that tax credits are based on is about $716. Most people who qualify for a credit pay far less; see the examples above.
Does Montana have Medicaid expansion?
Yes. Households under 138% of the federal poverty level are generally covered by Medicaid rather than a Marketplace credit.
Where do Montana residents enroll in a Marketplace plan?
Montana uses HealthCare.gov. Open Enrollment for 2027 runs November 1 to mid-January; outside that window you need a qualifying life event.
Are private health plans cheaper than the Marketplace in Montana?
Often, for healthy households that do not qualify for a tax credit. A healthy 40-year-old man is typically quoted $152 to $498 a month on private plans in Montana, versus $505 to $621 for Marketplace Bronze at full price. Private plans are medically underwritten and are not ACA plans, so anyone with a tax credit or ongoing conditions usually does better on the Marketplace.
