Montana income tax in 2026
Montana taxes wages at 4.7% to 5.65% of taxable income. Montana starts from federal taxable income, so the federal standard deduction ($16,100 single, $32,200 joint, $24,150 head of household) applies and there are no personal exemptions. People 65 or older subtract a further $5,660 each.
