Montana Income Tax Overview

Montana has a two-bracket income tax system with rates of 4.7% on income up to $47,500 and 5.65% on income above that threshold — simplified from a previously more complex multi-bracket structure. Montana's standard deduction mirrors the generous federal amount ($16,100 for single filers), meaning a significant portion of income is sheltered before either rate applies. A notable advantage: Montana has no statewide sales tax, which improves overall purchasing power compared to neighboring states like Idaho (6% sales tax) and Wyoming (4% state sales tax). No Montana city charges a local income tax on wages.

Here's what a single Montana filer keeps in 2026. On a $50,000 salary, take-home is approximately $40,572 per year ($3,381/month) after federal, FICA, and state taxes. At $80,000, take-home is approximately $61,419 ($5,118/month), with the state taking $3,159. At $100,000, you keep about $74,359 ($6,197/month), with $4,289 going to Montana. At $150,000, take-home is approximately $106,068 ($8,839/month), with the state taking $7,114. The generous standard deduction keeps the effective rate around 4.7% for most middle-income earners, with the 5.65% bracket kicking in only on income above $47,500.

Compared to neighboring Wyoming (no income tax), a Montana worker at $80,000 takes home approximately $3,159 less per year — the full cost of Montana's income tax relative to Wyoming. Against Idaho (flat 5.3%), Montana workers at $80,000 pay roughly $228 less in state income tax, making Montana slightly better for most earners. Against North Dakota (dramatically lower rates), Montana workers at $80,000 pay approximately $2,500 more. Montana's no-sales-tax advantage partially offsets the income tax gap with Wyoming for high-spending households.

Watch out: The cost of living in Montana has risen substantially, particularly in Bozeman and the Flathead Valley, as remote workers and retirees relocate from California and other high-cost states. The "Montana discount" on housing has narrowed significantly in recent years. Tax savings compared to California or the Pacific Northwest are still real and meaningful, but the cost-of-living calculation is no longer as simple as it was five years ago. Factor current housing, services, and healthcare costs into any comparison — not just the income tax rate.
