Every Montana employer owes federal payroll taxes: Social Security and Medicare withholding under FICA, and federal unemployment tax (FUTA), regardless of what Montana itself requires. On top of that federal baseline, most states layer on their own obligations: income tax withholding, state unemployment insurance (SUI), and in some cases disability or paid-leave programs. Whether each of these applies, and at what rate, depends on Montana law. The first step for any new employer is registering with the right state agencies before running the first payroll. Our new employer payroll setup checklist walks through that process.
Minimum wage and overtime rules start with the federal Fair Labor Standards Act (FLSA), but Montana may set a higher minimum wage, stricter overtime triggers, or additional rules around tipped employees and meal or rest breaks. Overtime is generally 1.5 times the regular rate after 40 hours in a workweek under federal law, though some states calculate it differently. The FLSA employer guide covers the federal floor that every employer must meet before layering on Montana-specific requirements.
Final paycheck timing, new hire reporting deadlines, and pay stub requirements also vary by state. Missing a new hire report or paying a final check late can trigger penalties even when the payroll math itself was correct. New hires must be reported to the state's new hire registry, typically within a short window of the hire date, and every employer needs a state UI account number before the first unemployment filing is due.
For ongoing compliance, most employers file federal Form 941 quarterly, deposit federal withholding on a schedule based on prior-year liability, and file state withholding and unemployment returns on whatever schedule Montana assigns. Our federal payroll compliance checklist lays out the recurring tasks by frequency: new hire, every payroll, monthly, quarterly, and annual.
Rates, wage bases, and deadlines change from year to year and are specific to Montana. See the guides below for current Montana figures, or check directly with your state's revenue and labor agencies before filing.
Employers in Montana pay federal payroll taxes: Social Security and Medicare (FICA) and federal unemployment tax (FUTA), plus any state-level payroll taxes that apply, such as state income tax withholding and state unemployment insurance (SUI). Rates and wage bases vary and change annually, so always confirm current figures with your state's labor and revenue agencies.
Minimum wage in Montana is set by a combination of federal and state law, and the higher of the two rates always applies. Rates are reviewed regularly and can change from year to year, so check your state labor department's website for the current figure before running payroll.
New employers generally need a federal Employer Identification Number (EIN) from the IRS, plus registration with Montana's revenue department for state income tax withholding (where applicable) and its labor or workforce agency for state unemployment insurance. See our Montana guides for step-by-step registration instructions.
