Montana consolidated its 7-bracket system to just two brackets (4.7% and 5.9%) in 2026 — paired with a federal-conforming standard deduction. The median household income in Montana is approximately $66,800 — meaning a $100,000 salary is $33,200 above the state median, and $19,390 above the US national median household income of $80,610.
Montana's cost of living index is 102 (US average = 100), so your $74,476 net pay has the purchasing power of approximately $73,016 in an average-cost state. Billings, Missoula, and Great Falls all sit near the national cost-of-living average.
