Montana income tax in 2026
Montana uses progressive brackets. Standard deduction: $16,100 single, $32,200 married filing jointly, $24,150 head of household.
| Rate | Single: taxable income over | Married jointly: over |
|---|---|---|
| 4.7% | $0 | $0 |
| 5.65% | $47,500 | $95,000 |
What makes Montana different
Montana simplified its income tax to two brackets in 2024 and now uses federal taxable income as the starting point. A 2025 law widened the lower bracket so most middle-income workers pay only 4.7%. Montana has no general sales tax, so the income tax is its main tax on residents.
- H.B. 337 cut Montana’s top rate to 5.65% for 2026 (5.4% in 2027) and widened the 4.7% bracket to $47,500 of taxable income for single filers.
- Montana starts from federal taxable income, so the federal standard deduction applies.
