How Montana paycheck tax works
Montana has a two-rate income tax for 2026: 4.7% and a top rate of 5.65%. Montana withholding mirrors the federal method with no state allowances; the standard deduction is built in as a 0%-rate band ($16,100 single / $32,200 married / $24,150 head of household), and Form MW-4 filing status selects the schedule. Montana withholds supplemental wages at 5.65% (its top rate).
The calculator annualizes your pay, then runs Montana's 2026 graduated withholding alongside federal income tax and FICA. It's a close estimate rather than an exact match: your actual paycheck can differ from your employer's payroll, which may use exact per-period tables.
