The standard W-2 estimate uses the official finite Montana 2026 wage-bracket tables and does not extrapolate beyond those tables.
Monthly wages at or above $11,000, semimonthly at or above $5,500, biweekly at or above $4,700, weekly at or above $2,400, daily at or above $330, and annual at or above $132,000 need a user-entered Montana withholding amount until the DOR formula rounding question is resolved.
Local, nonresident, multistate, reciprocity, tribal, military, agricultural, and employer-specific cases require user-entered source wages or are outside this standard W-2 estimate.
Montana 2026 state withholding is calculated from the official Department of Revenue wage-bracket tables for ordinary W-2 wages within the published table ranges.
The calculator uses explicit Montana MW-4 entries and optional Montana-source wage inputs; it does not infer local, nonresident, or employer-specific facts.
This is a standard W-2 paycheck estimate, not a full employer payroll compliance engine.
Montana formula-only withholding above the finite published table ranges is not calculated because the official rounding/precision treatment remains unresolved; enter a known Montana withholding amount for those paychecks.
Local, nonresident, multistate, reciprocity, tribal, military, agricultural, and employer-specific cases require user-entered source wages or separate review.
Formula-only withholding for wages above official finite table ranges unless a known withholding amount is entered
Automatic nonresident, multistate, reciprocity, tribal, military, agricultural, or interstate transportation determinations
Employer unemployment insurance, workers compensation, return filing, deposit, or reporting obligations
Montana payroll tax years outside 2026

Example calculation

A worker can enter biweekly gross pay, W-4 amounts, pre-tax deductions, and year-to-date wages. The result separates federal income tax, Social Security, Medicare, any verified state tax, total deductions, and net pay.
