Cost of Living in Montana 2026

Q: Is Montana an expensive state to live in?

Montana's overall cost of living index is approximately 102 — about 2% above the national average. The picture varies wildly by city. Bozeman has experienced a dramatic surge in housing costs, with median home prices around $750,000 and an index above 130. Billings, Great Falls and Missoula remain meaningfully more affordable, with median home prices in the $360,000–$520,000 range. Montana has no sales tax, which is a meaningful advantage on big-ticket purchases.

Q: What is Montana's tax structure?

Montana has no state sales tax — one of just five US states without one. The state income tax was simplified in 2024 to two brackets: 4.7% on the first roughly $20,000 (single) and 5.9% above that. Property taxes average around 0.74% of assessed value, below the national median. The combination of no sales tax + low property tax makes Montana relatively tax-friendly despite a moderate income tax.

Q: Is Montana a good place to retire?

Montana has trade-offs for retirees. The no-sales-tax structure is a clear advantage. Property taxes are low. The state taxes Social Security but excludes the first roughly $32,000 for many retirees. The big concerns are healthcare access (limited specialists outside Billings and Missoula), winter severity, and the high cost of housing in the most desirable retirement towns. Whitefish and Bozeman are popular but expensive; Billings and Helena offer better value.

Montana is a tale of two states. Bozeman and the resort towns have seen explosive housing appreciation thanks to remote worker influx and Yellowstone proximity. Billings, Missoula and Great Falls remain genuinely affordable. The state's biggest tax advantage: no state sales tax.
