Retire in Montana: Cost, Taxes & FIRE Number for 2026
Montana offers dramatic Big Sky scenery and a #21 healthcare ranking — but its C tax grade, 6.75% top income tax, and partial Social Security taxation require careful planning for retirees seeking maximum income efficiency.
What It Costs to Retire in Montana
The average retiree in Montana spends about $53,000 a year ($4,417/month), based on BLS spending data for households 65 and older, adjusted for Montana's cost of living. That works out to a standard retirement number of $1,325,000 under the 4% rule, or $1.51M for early retirees using the more conservative 3.5% FIRE withdrawal rate.
Montana earns a C retirement tax grade from Plootus Research. The state's 6.75% top marginal income tax rate is above average, and Montana partially taxes Social Security benefits — following federal combined income rules to determine the taxable portion. Pension income and IRA withdrawals are generally taxable, contributing to a meaningful state tax burden for most retirees drawing from retirement accounts.
Montana's appeal for retirees lies largely in its extraordinary landscape: Glacier National Park, Yellowstone access, world-class fly fishing, and vast open spaces attract active retirees in droves. The state's #21 healthcare ranking is above average, with reasonable coverage in major cities — though Montana's geography means rural residents may face long drives to reach specialists.

Montana Retirement Tax Overview
State Income Tax
Montana's top marginal income tax rate of 6.75% applies to income above approximately $20,500 — a relatively low threshold, meaning many retirees drawing from retirement accounts will face this top rate. Pension income and IRA withdrawals are fully taxable at ordinary income rates, and Montana offers limited retirement-specific deductions compared to more retiree-friendly states.
Social Security Tax
Montana partially taxes Social Security benefits using federal combined income thresholds. Retirees with combined income above $34,000 (single) or $44,000 (married) may have up to 85% of their Social Security benefits subject to Montana state income tax. This is a meaningful consideration for retirees who rely significantly on Social Security income, and contributes to Montana's C retirement tax grade.
Healthcare in Retirement in Montana
Montana ranks #21 nationally for healthcare quality — a slightly above-average result for a state with such a large and sparsely populated geography. Billings Clinic, Benefis Health System in Great Falls, and Providence St. Patrick Hospital in Missoula are among the state's strongest facilities. However, Montana's vast size means that retirees in many areas face significant travel times to reach specialists or tertiary care.
HC Rank #21: Montana sits above the national median for healthcare quality, a solid result for its size and population density. Retirees in Billings, Missoula, or Great Falls will have reasonable access to quality care. Those in more remote areas — eastern Montana or mountain communities — should plan for longer travel times to reach specialists and may want to factor telemedicine access into their retirement planning.
Frequently Asked Questions: Retiring in Montana
Montana earns a C retirement tax grade driven by its 6.75% top income tax rate and partial taxation of Social Security benefits. Average annual retirement spending runs about $53,000, requiring roughly $1,325,000 in savings under the standard 4% rule. Montana's extraordinary natural scenery and outdoor lifestyle appeal strongly to active retirees, but the tax environment and middle-tier healthcare ranking are meaningful trade-offs.
Montana partially taxes Social Security benefits, which is a caution for retirees. The state follows federal rules for determining how much of Social Security income is taxable at the state level — meaning retirees with higher combined income may see a portion of their Social Security subject to Montana's income tax. This is one factor contributing to the state's C retirement tax grade.
Using the standard 4% rule, retiring in Montana on its average annual cost of $53,000 requires approximately $1,325,000 in savings. That figure excludes Social Security, which most retirees layer on top. Montana's cost of living has risen significantly in recent years due to remote-work migration, particularly in popular areas like Missoula, Bozeman, and Whitefish.
At a 3.5% safe withdrawal rate — the more conservative rate recommended for early retirees facing a 40–50+ year horizon — Montana's FIRE number is approximately $1.51M, based on its $53,000/year average cost. Early retirees in Montana should carefully budget for healthcare before Medicare eligibility at 65, as the state's rural nature can limit specialist access.
Montana ranks #21 nationally for healthcare quality — a slightly above-average position. Larger cities like Billings, Missoula, and Great Falls have solid regional hospital systems. However, Montana's vast geography means that many retirees in rural areas face long travel times to access specialists or advanced care — a significant practical consideration despite the reasonable state-level ranking.
