Estimate only: this is an approximation, not a copy of Montana's withholding tables. It annualizes your pay, subtracts the zero-tax band built into Montana's annual withholding table and applies the 4.7% and 5.65% rates. Your employer follows the Montana Employer and Information Agent Guide with your own Form MW-4 elections, so your actual withholding will differ. Use the Montana Department of Revenue's own withholding tax tables for an official figure.

What is the Montana income tax rate for 2026?
Montana uses graduated income-tax brackets, applied here to annualized wages after the state's standard deduction and exemptions. The figure was transcribed from Montana Department of Revenue — Montana Employer and Information Agent Guide with Montana Withholding Tax Tables, Montana Withholding Tax Formula (Annual Payroll Period) and verified on 2026-07-31. Because withholding tables and annual calculations differ slightly, treat the result as an estimate and check it against the state's own table.
Why does this differ from my actual pay stub?
Two reasons. Pre-tax items — retirement contributions, health premiums, HSA deductions — reduce taxable pay and are not modelled here. And this uses an annualized approximation of the state's schedule rather than the exact withholding tables your employer's payroll system uses, which is disclosed on every result.
