Montana payroll taxes and rules for 2026
Montana withholds state income tax using a two-bracket formula (4.7% and 5.65% for 2026) applied to gross wages after 401(k) and Section 125 deductions, with the 0% bracket sized to match the federal standard deduction. There is no state disability insurance, no state paid-leave program, and no local income tax anywhere in Montana. Employers also pay state unemployment insurance (SUI) and a separate 0.18% Administrative Fund Tax on the same wage base.
- Income tax
- 4.7% to 5.65% (two brackets for 2026) · Employee form: Form MW-4
- Montana simplified its withholding system for 2026 (House Bill 337, 2025 session): two brackets, 4.7% and 5.65%, replacing the old allowance-based system.
- The 0% bracket is sized to match the federal standard deduction for the employee's filing status ($16,100 single/MFS, $32,200 MFJ, $24,150 head of household, annualized). Montana no longer uses its own personal exemptions, standard deduction, or allowance count for withholding.
- Traditional 401(k) deferrals and Section 125 cafeteria-plan deductions (health/dental/vision premiums, FSA, HSA) both reduce Montana taxable wages, because both are excluded from the employee's federal adjusted gross income.
- Married couples filing jointly where both spouses work can check MW-4 line 2 to withhold at the narrower Single/MFS bracket thresholds instead of the wider MFJ thresholds, to avoid under-withholding.
- Employer taxes
- State Unemployment Insurance (SUI): 0.00% to 6.12% (2026 Rate Schedule 1); new employers 1.00% to 2.00% by industry 2026 taxable wage base is $47,300. New-employer rate depends on NAICS industry classification, not a single flat rate.
- Administrative Fund Tax (AFT): 0.18% (0.13% for Eligible Rate Classes 01-02) Charged on the same $47,300 wage base as SUI, but appears as its own line on Montana's UI contribution report.
- Local taxes
- No Montana city or county levies a local income or payroll tax.
- Bonuses
- Employers may withhold on supplemental wages (bonuses, commissions) by combining them with regular wages for the current or prior pay period, or by using a flat 5% rate on the supplemental amount alone.
- Minimum wage 2026
- $10.85/hour Adjusted every January 1 by the CPI-U (August-to-August change), rounded to the nearest 5 cents. Montana does not allow a tip credit; tipped employees must receive the full minimum wage before tips.
- Pay frequency
- No statewide mandatory minimum pay frequency is set in statute beyond paying wages due; most employers pay at least monthly.
- Final paycheck
- Montana requires final wages be paid immediately upon involuntary discharge, or by the next regular payday (or within 15 days, whichever is earlier) if the employee quits.
- New-hire reporting
- Montana employers must report new hires to the Montana New Hire Reporting program within 20 days of the hire date.
- Reciprocity
- North Dakota residents working in Montana are not subject to Montana withholding under a reciprocity agreement (employee must file Form MW-4, line 5).

Montana paycheck questions
Does Montana still use personal allowances or a state standard deduction for withholding?
No. Starting with tax year 2026, Montana's withholding formula uses only the federal standard deduction amount for the employee's filing status as the 0% bracket ceiling. Montana-specific allowances and itemized/standard deduction elections no longer affect withholding.
Do 401(k) and health insurance (Section 125) deductions reduce Montana withholding wages?
Yes. Both are excluded from the employee's federal adjusted gross income, and Montana's guide ties withholding-wage exclusions to federal AGI exclusion, so both reduce the wages subject to Montana withholding.
Is there a Montana state disability or paid family leave tax?
No. Montana has no state disability insurance (SDI) program and no state paid family and medical leave program, so there is no employee-paid payroll deduction for either.
What is the Administrative Fund Tax and is it part of the SUI rate?
No, it's separate. The AFT is 0.18% (0.13% for the best-rated employers) charged on the same unemployment-insurance taxable wage base, but it is reported as its own line on Montana's quarterly UI contribution report, not folded into the SUI contribution rate.
How much is $60,000 a year after taxes in Montana?
About $48,326 a year, or $1,859 every two weeks, for a single filer with no other W-4 adjustments in 2026. Federal income tax is $5,020, Social Security and Medicare $4,590, and Montana taxes and payroll deductions $2,064.
What does a $60,000 employee cost an employer in Montana?
$65,190 a year before benefits: the salary plus the 7.65% FICA match, federal unemployment (FUTA) and Montana unemployment insurance at the new-employer rate of 1% on the first $47,300, plus employer-paid state programs.
