Montana Labor Law Guide 2026: Wages, Overtime, Wrongful Discharge, and Pay

Montana is the one state where at-will employment does not apply once an employee finishes probation. Its Wrongful Discharge from Employment Act requires good cause for termination after the probationary period, which changes how employers document performance and discipline. The Montana Department of Labor and Industry's Employment Standards Division enforces the Wage and Hour Payment Act, the minimum wage, and child labor rules, and it publishes detailed FAQs on pay timing, deductions, and vacation.

Minimum Wage in Montana

Montana's minimum wage is $10.85 per hour for 2026, adjusted every January 1 for inflation. Businesses with gross annual sales of $110,000 or less that are not covered by the FLSA may pay $4.00 per hour, but as the Department notes, employees covered by federal law "must receive the greater of federal ($7.25) or state minimum wage." Montana is one of seven states with no tip credit; the FAQ states that "Employers may not use tips as credit toward wage rates, including minimum wage."

The 2027 rate will be announced in the autumn of 2026. The Montana minimum wage guide covers the indexing formula, the small business tier, and the rate history.

Overtime Rules

Montana requires overtime at 1.5 times the regular rate for hours over 40 in a workweek. There is no daily overtime. The Department's FAQ is precise: "Overtime pay is not required unless an employee actually worked more than 40 hours," so paid holidays and PTO hours do not count toward the threshold unless the employer's policy says otherwise.

Worked example at the state minimum: an employee at $10.85 who works 45 hours earns $434.00 for 40 hours plus $81.38 for 5 overtime hours at $16.275, or $515.38 gross. Use the overtime calculator for other rates.

Montana exempts agricultural workers and executive, administrative, professional, and outside sales employees under tests that track the federal ones, and it applies the federal $684 per week salary floor. Some seasonal and student workers have separate rules. Our overtime pay laws in the US guide explains the regular-rate calculation.

Meal and Rest Breaks

The Department is direct: "There is no state or federal law that requires an employer to give a break." Where an employer does provide breaks, the federal rules apply.

Break type	Requirement	Applies to
Meal break	Not required; an unpaid meal period must be at least 30 minutes with the employee completely relieved of duty	All employees
Rest break	Not required; any break shorter than 30 minutes must be paid	All employees
Minors	No state break requirement beyond federal rules	Under 18
Lactation	Reasonable unpaid break time and a private space under state and federal law	All employers

See the rest and meal break laws by state guide and the break time calculator.

Paid Sick Leave and Other Leave

Montana has no paid sick leave law. Leave obligations come from federal law and a few state statutes, including one of the more generous maternity leave rules among small-state employers.

Leave type	Montana rule
Paid sick leave	Not required
Family and medical leave	Federal FMLA; the Montana Maternity Leave Act requires a reasonable leave of absence for pregnancy and childbirth at employers of any size
Jury duty	Employers may not discharge an employee for jury service; unpaid unless policy provides pay
Voting	No general statute requiring time off
Military	Federal USERRA plus state protection for National Guard members
Crime victims	Protected leave to attend court proceedings

The Maternity Leave Act applies regardless of employer size and prohibits terminating an employee because of pregnancy. See paid sick leave laws in the US and jury duty laws in the US.

PTO Payout and Final Paychecks

Montana's final pay rules differ by how the employment ended. On discharge, the Department states that "all wages are due immediately (within four hours or end of the business day, whichever occurs first)" unless the employer has a pre-existing written policy that extends payment, and even then not "beyond the next regularly scheduled pay date or fifteen (15) calendar days, whichever occurs first." When an employee quits, wages are due "on the next scheduled payday for the period in which the employee was separated, or 15 calendar days, whichever occurs first." Late payment exposes the employer to a penalty of up to 110 percent of the wages due.

Vacation is wages in Montana. The FAQ says plainly that "'use it or lose it' policies are not permitted in Montana," and earned vacation must be paid out at separation. Employers can cap accrual going forward but cannot take away time already earned. Our PTO payout laws by state guide lists Montana with California, Colorado, and Nebraska on this point.

Pay frequency: Montana does not mandate a specific frequency, but wages must be paid "within 10 business days after the end of the pay period." Deductions for shortages or damage are prohibited; lawful deductions are limited to taxes, garnishments, and written agreements for items such as board and lodging.

Exempt vs Non-Exempt Employees

Montana applies exemption tests that follow the federal categories and the $684 per week salary floor. The state's Wrongful Discharge Act does not depend on exempt status, so a salaried exempt manager has the same good-cause protection after probation as an hourly agent. Our exempt vs non-exempt employees guide and the FLSA exemption flowchart cover the classification analysis.

Child Labor Rules

Montana's child labor law sets a minimum working age of 14 with narrow exceptions. Montana does not require work permits, but employers must verify age and follow the hour limits in the Department's child labor reference guide.

Age group	School in session	School not in session	Hours of day	Other rules
14 and 15	3 hours on a school day, 18 hours in a school week	8 hours on a non-school day, 40 hours a week	7 AM to 7 PM; until 9 PM June 1 through Labor Day	No work during school hours
16 and 17	No hour limits	No hour limits	No restriction	Barred from 17 hazardous occupations unless in an apprenticeship or student-learner program
Under 14	Not permitted except exempt activities such as newspaper delivery and family farms

The reference guide lists the hazardous occupations, which include mining, logging, roofing, and power-driven machinery. See child labor laws in the US for the federal baseline.

Other Montana Employment Rules

• Wrongful Discharge from Employment Act. After the probationary period, a discharge is wrongful if it "was not for good cause," if it retaliates against an employee for refusing to violate public policy or reporting a violation, if the employer violated its own written personnel policy, or, since a 2021 amendment, if the employee was fired solely for lawful speech including on social media. The default probationary period is 12 months and can be extended by up to 6 more months before it expires. Damages are capped at 4 years of lost wages and benefits, and employers with a written internal grievance procedure can require employees to use it first.
• Written personnel policies. Because violating a written policy is itself grounds for a wrongful discharge claim, handbooks should describe discipline as discretionary rather than as a guaranteed sequence.
• Non-compete agreements. Disfavored under state law and enforced only when reasonable in scope and supported by consideration.
• Drug testing. The Montana Workforce Drug and Alcohol Testing Act limits testing to hazardous, safety, security, and fiduciary positions and requires a written policy.
• Recreational marijuana. Employers may still prohibit use and impairment at work, but lawful off-duty use is protected in most roles.
• Pay statements. Employers must give employees an itemized statement of deductions each pay period.

Hiring, Termination, and Record-Keeping

Montana is the exception to at-will employment. The Department's FAQ points employers to the Wrongful Discharge from Employment Act, which means termination decisions after probation need documented good cause: a legitimate business reason or the employee's failure to perform, disruption of operations, or other job-related grounds. The Montana Human Rights Bureau enforces the state anti-discrimination law, which covers employers of any size.

Keep payroll records showing hours worked, wages, deductions, and pay statements for at least 3 years, and keep age verification for minors. Post the state minimum wage notice, the unemployment and workers' compensation notices, and the federal posters. Because good cause has to be shown with records, a time card calculator, a written timekeeping policy, and consistent attendance data are part of the termination file in Montana, not just payroll inputs.
