Montana Payroll Tax Steps
Montana’s straightforward tax system makes payroll manageable if you follow the right steps. Our calculator ensures accuracy whether you’ve got one ranch hand or an office full of professionals.
Here are some key steps you’ll have to take to make smarter payroll decisions.
Step #1: Register with the Department of Revenue and Unemployment Insurance Division
To hire employees, register with the Montana Department of Revenue for income tax withholding and with the Department of Labor & Industry’s Unemployment Insurance Division.
New employers pay 1.0% unemployment tax on the first $43,000 of wages for each employee.
Step #2: Understand Montana’s Payroll Taxes
Montana’s progressive income tax ranges from 4.7% to 5.9%, based on income. Employers must also handle FICA (Social Security and Medicare) and FUTA contributions at the federal level.
Step #3: Minimum Wage & Overtime Rules
The state minimum wage is $10.30/hour (2025).
Overtime follows federal law — 1.5× regular pay after 40 hours per week.
Step #4: Pay Frequency & Final Pay Rules
Montana allows employers to set their own pay frequency (weekly, biweekly, or semimonthly), but you must maintain a consistent schedule.
Final wages are due by the next regular payday or within 15 days of separation, whichever comes first.
