The rules in detail

Montana requires overtime after 40 hours a week under state law, filling gaps for employers not covered by the FLSA.

Enforcement: Montana Department of Labor and Industry.

Worked example

A Billings warehouse worker at $18/hour with a 42-hour week earns 2 × $27 overtime.

What Montana employers sometimes get wrong

Montana is the only state where at-will employment has a statutory "good cause" notice requirement — but its overtime trigger is a standard 40-hour week.

Who is entitled to overtime

Overtime rules protect “non-exempt” employees. The main federal exemptions cover executives, administrators, professionals, outside salespeople and certain computer employees — provided their duties genuinely match the exemption and they clear the salary basis test. Job titles mean nothing: an “assistant manager” who mostly runs a register is still non-exempt in the eyes of the law.

In practice, most hourly workers in Montana are non-exempt and must receive overtime whenever the rules above trigger. Independent contractors are not covered — but misclassifying an employee as a contractor is one of the most common wage violations.

How to file an overtime claim in Montana

Check your pay stubs and hours against the calculator above first. If you believe you were shorted, you can file a wage claim with Montana Department of Labor and Industry or a complaint with the U.S. Department of Labor’s Wage and Hour Division (dol.gov/agencies/whd). The FLSA lets you recover unpaid overtime going back two years (three for willful violations), often doubled as liquidated damages.

Questions people ask

What are the overtime laws in Montana?

Montana requires overtime after 40 hours a week under state law, filling gaps for employers not covered by the FLSA. The practical rule: 1.5× after 40 h/wk (state law). Source: Mont. Code § 39-3-405.

How is overtime calculated in Montana?

Multiply your regular hourly rate by 1.5 for every overtime hour. For example, at $20/hour a 45-hour week pays 40 × $20 + 5 × $30 = $950.

Do salaried employees get overtime?

Sometimes. A salary alone does not remove overtime rights — the employee must also perform exempt duties and (for the federal white-collar exemptions) clear the salary threshold. If the exemption tests fail, the employee is owed overtime regardless of pay format.

Does Montana require overtime on weekends or holidays?

Federal FLSA rules do not require premium pay for weekends or holidays unless total weekly hours exceed the overtime threshold. Some state or employer policies may be more generous.
