The calculator annualizes your gross wages based on pay frequency, estimates a simplified taxable wage base using federal standard deduction and allowance-style offsets, applies Montana’s two-tier ordinary income tax with filing-status-specific first-tier cutoffs, adds federal bracket tax and FICA payroll taxes, then returns a per-pay-period take-home estimate.

Montana Form 2 and Montana-specific additions, subtractions, and credits are not modeled line-by-line here.
Gross wages flow through federal tax, Montana state tax, and FICA to produce net pay.
