Montana Overtime Law: Daily Overtime, the 40-Hour Rule, and Exemptions

In Montana, overtime is owed at one and one-half times your regular rate of pay for every hour worked over 40 in a single workweek — and Montana does not require daily overtime. Unlike California, Alaska, Nevada, or Colorado, Montana has no rule that pays a premium for working more than 8 (or 12) hours in a day. What matters is the seven-day workweek total: cross 40, and the extra hours must be paid at time-and-a-half. This rule comes from Montana's Minimum Wage and Maximum Hours Act, codified at Montana Code Annotated (MCA) § 39-3-405, and it tracks the federal weekly-40 standard rather than adding a daily layer on top of it.

The core rule: weekly 40, not daily 8

Montana law mirrors the federal Fair Labor Standards Act (FLSA) on the basic overtime trigger. An employee who is not exempt must receive overtime pay of at least 1.5 times the regular rate for hours worked beyond 40 in a workweek. A "workweek" is a fixed and regularly recurring period of 168 hours — seven consecutive 24-hour days. It does not have to match the calendar week, but once an employer sets it, it should stay consistent.

Because there is no daily overtime in Montana, an employee who works four 10-hour days (40 hours total) is generally owed no overtime, even though several days exceeded 8 hours. By contrast, someone who works 45 hours in a week is owed 5 hours at time-and-a-half, regardless of how those hours were spread across the days. Employers also may not average hours across two weeks to avoid overtime: each workweek stands on its own.

What counts as the "regular rate"

Overtime is calculated on your regular rate, not just your base hourly wage. The regular rate generally includes nondiscretionary bonuses, shift differentials, and certain commissions — not only the posted hourly figure. This means the true overtime rate can be higher than 1.5 times the base hourly wage. For salaried non-exempt employees, the regular rate is calculated by converting the salary to an hourly equivalent for the hours it is intended to cover.

Montana's minimum wage and the federal floor

Overtime is built on top of the minimum wage, so it helps to know both. The federal FLSA sets a minimum wage of $7.25 per hour and requires overtime after 40 hours per week. Montana sets a higher state minimum wage that is adjusted every year for inflation under MCA § 39-3-409. As a reference point, Montana's minimum wage was $10.55 per hour in 2025, and it increases on January 1 each year. Because the figure changes annually, confirm the current 2026 rate directly with the Montana Department of Labor & Industry before relying on a specific number. Whenever Montana's minimum wage exceeds the federal $7.25, the higher Montana rate governs work performed in the state.

Montana also has a narrow lower minimum-wage tier for very small businesses (those not covered by the FLSA with annual gross sales of $110,000 or less), but most employees are covered by the standard rate. Overtime obligations still apply based on the employee's actual regular rate.

Who is exempt from Montana overtime

Not every worker is entitled to overtime. Montana's exemptions are listed at MCA § 39-3-406 and largely parallel the federal categories. Common exemptions include:

• Executive, administrative, and professional employees — the "white-collar" exemptions, which require both a salary basis and specific job duties. A job title alone is not enough; the actual duties control.
• Outside salespersons who regularly work away from the employer's place of business.
• Certain agricultural and farm workers, subject to detailed conditions.
• Some commissioned employees of retail or service establishments.
• Specific transportation workers and other categories where federal law sets hours standards.

Being paid a salary does not automatically make you exempt. To qualify for the white-collar exemptions, an employee generally must be paid on a salary basis at or above the applicable federal salary threshold and perform exempt duties. Misclassification — labeling an hourly worker as a salaried "manager" who really spends the day doing non-managerial tasks — is one of the most common ways employees lose overtime they are legally owed. If you are unsure, the duties test, not the paycheck label, decides the question.

How to recover unpaid overtime in Montana

If you believe you were not paid overtime you earned, you have two main avenues in Montana.

1. File a wage claim with the Department of Labor & Industry

Montana's Department of Labor & Industry (DLI) — through its Wage and Hour Unit / Employment Standards Division — investigates unpaid-wage and overtime claims at no cost to the employee. You submit a wage claim describing the hours worked and wages owed, and the Department can order the employer to pay. Under Montana's Wage Protection Act, unpaid wages can carry a penalty in addition to the wages themselves (commonly assessed as a percentage of the unpaid amount under MCA § 39-3-206), which is designed to discourage employers from withholding pay.

There is a deadline. Montana law sets a statute of limitations for wage claims, and the period for filing with the Department is limited (generally measured in years from when the wages were due under MCA § 39-3-207). Because the exact limitation period and any penalty calculation depend on the facts and the version of the statute in effect, verify the current deadline with DLI or an attorney before you file — do not assume you have unlimited time. The sooner you act, the more of your back wages you can typically recover.

2. Pursue a court claim under state or federal law

You may also sue to recover unpaid overtime. Federal FLSA claims generally allow recovery of back pay plus an equal amount in liquidated (double) damages, with a two-year lookback (three years for willful violations). Montana state-law claims provide their own remedies and penalties. Many overtime cases are brought under both bodies of law. An employment attorney can advise which path — the administrative wage claim or a lawsuit — best fits your situation, and whether your claim can proceed individually or as part of a group.

Protect your records

Keep your own log of hours, schedules, pay stubs, and any messages about your schedule. Employers are required to keep accurate time and pay records, but having your own documentation strengthens a claim. Montana, like federal law, prohibits retaliation against employees who assert their wage rights, so you cannot be lawfully fired or punished simply for filing a good-faith wage claim.

Where to verify the current rules

For the authoritative and up-to-date details — the current minimum wage, claim forms, deadlines, and exemption guidance — consult the Montana Department of Labor & Industry and the Montana Code Annotated, Title 39, Chapter 3. Because wage figures change every January and statutory provisions are periodically amended, treat any specific dollar amount or deadline you read online as a starting point and confirm it with the official state source before acting.

Federal law and local ordinances may also apply. Federal laws like the Fair Labor Standards Act set a national floor, and your city or county may add protections (such as a higher local minimum wage or paid sick leave). Check both alongside Montana state law.
