State withholding methodology
Paycheck withholding is estimated from annualized wages, then converted into per-pay-period deductions. Federal withholding uses IRS 2026 bracket logic and standard deduction assumptions; state withholding uses Montana bracket data where applicable.

Paycheck taxes in Montana — what to expect
State withholding on a Montana paycheck follows 2 progressive brackets up to 5.90%, which means the state line grows faster than pay as income crosses each band — the reason a mid-year raise can shift withholding more than expected. Montana does not provide a separate state standard deduction — wages are taxed from the first dollar after any specific adjustments.
For a single filer earning $75,000, roughly $2,208.48 lands in the bank each biweekly payday in Montana (about $4,785.05 on a monthly cycle) after estimated federal and state tax and FICA. Montana has reciprocity with North Dakota.
Withholding here follows 2026 tables from Montana Department of Revenue (https://mtrevenue.gov/taxes/montana-tax-tables-and-deductions/). Your actual stub also reflects W-4 elections, pre-tax benefits and 401(k) deferrals, so treat these figures as the baseline before those adjustments.
