Montana income tax in 2026
Montana taxes income at 4.7% and 5.65% after the federal standard deduction.
House Bill 337 lowered the top rate to 5.65% for 2026 and widened the lower bracket to $47,500 (single), $71,250 (head of household) and $95,000 (joint). Montana starts from federal taxable income, so the federal deductions for tips and overtime premium pay also come off Montana taxable income.
- Standard deduction: the same as the federal one: $16,100 single, $32,200 married filing jointly, $24,150 head of household.
- 401(k): traditional contributions come out before Montana income tax, as they do for federal tax.
