How Montana withholding works

State form: MW-4.

Montana's formula is W = A + B x (G − C) per pay period: the A and C amounts and the B rate come from the table for your MW-4 status (1a single, married filing separately, or MFJ with both spouses working; 1b MFJ with one earner; 1c head of household), chosen by your annualized wages, and the result rounds to the nearest dollar.

Current parameters

formula	W = A + B x (G - C), where G = gross wages for the pay period, B = rate, A and C from the table for the employee's MW-4 status box and pay period; result rounded to nearest dollar. Annual-period table values shown; the guide publishes equivalent per-period (weekly/biweekly/semimonthly/monthly) A and C values.
annual table status 1a single mfs or mfj both working	3 entries (see the cited publication)
annual table status 1b mfj or qualifying surviving spouse	3 entries (see the cited publication)
annual table status 1c head of household	3 entries (see the cited publication)
zero bracket note	The 0% band tops equal the 2026 federal standard deductions ($16,100 single / $32,200 MFJ / $24,150 HoH). House Bill 337 reduced the top rate from 5.9% to 5.65% for 2026 and allowances were abolished; the method mirrors the federal W-4 (steps 2-4 adjustments apply).
