Montana Overtime Pay Calculator

Montana follows the standard federal model on the calendar: non-exempt employees earn 1.5 times their regular rate for every hour worked beyond 40 in a single workweek. There is no daily overtime requirement in Montana, so an 11-hour shift followed by two days off does not trigger extra pay as long as the weekly total stays at or under 40. The Montana Minimum Wage and Overtime Act, found in Title 39, Chapter 3 of the Montana Code Annotated, largely mirrors the federal Fair Labor Standards Act but is enforced independently by the state.

One quirk worth knowing: Montana has its own minimum wage that adjusts annually for inflation, set at $10.55 an hour for 2026, and businesses with gross annual sales under $110,000 that are not covered by the FLSA may pay a lower state minimum of $4.00 an hour to those employees — though overtime still applies once 40 hours are worked. Ranch, farm, and some seasonal recreation workers face separate wage rules that reduce or eliminate overtime obligations, so job type matters as much as hours worked.

Because Montana is an employment-at-will state without daily overtime, workers scheduling four 10-hour days routinely receive no overtime premium at all, which surprises people moving from states like California or Nevada.

The Montana Department of Labor and Industry's Employment Relations Division investigates unpaid overtime claims through its Wage and Hour Unit. Workers can file a wage claim online or by mail, and the state acts as an active investigator rather than just a referral service — it can order back pay and, in some cases, penalty wages equal to 55% or 110% of the amount owed depending on whether the employer's conduct was found unreasonable. Claims generally must be filed within two years of the unpaid wages, extending to three years for willful violations.

A recurring trap is misclassification of retail, restaurant, and construction supervisors as 'salaried managers' without verifying they actually spend most of their time on genuine managerial duties and earn at least the required salary threshold. Montana also has no state law requiring meal or rest breaks for adult workers, so employers sometimes wrongly assume that flexibility extends to overtime rules, when it does not — the 40-hour threshold is firm regardless of break policy.

Tipped workers in Montana must still be paid the full state minimum wage before tips, since Montana does not allow a tip credit against its state minimum — a more worker-favorable rule than the federal $2.13 tipped minimum.

Where Montana and federal law diverge is mostly in coverage and enforcement, not in the overtime formula itself. Both require time-and-a-half after 40 hours in a workweek, and both define exempt executive, administrative, and professional employees similarly, though Montana's Wage and Hour Unit sometimes applies its own duties tests during audits. When state and federal rules conflict, the employee is entitled to whichever standard produces the higher pay — in Montana's case, that is usually the state's no-tip-credit rule for tipped workers or its independent wage claim process, which can move faster than a federal Department of Labor complaint.

Employees who believe they were shorted overtime pay in Montana are not required to choose only one avenue — filing a state wage claim does not prevent also filing a federal complaint with the U.S. Department of Labor's Wage and Hour Division, though most workers only need to pursue one since the underlying facts and remedy are similar.
