The Montana Final Paycheck Law Deadline
If the employer fires you or lays you off, the Montana final paycheck law sets the due date like this: immediately on separation if you were fired for cause or laid off, unless a pre-existing written personnel policy extends it to the next regular payday or 15 days, whichever is first (Mont. Code 39-3-205). Montana’s definition of wages includes bonuses, and commissions are treated as money due the worker.
Earned commissions and bonuses generally belong in the final check the same way hourly pay or salary does. Whether a commission or bonus was “earned” by your last day usually depends on your written commission plan or pay agreement, so confirm with the state agency.
Enter your last day and how the job ended, and get the exact Montana due date, the statute and the penalty if it is late.

Montana Final Paycheck Law If You Quit
If you quit, the Montana final paycheck law rule is: next regular payday for the pay period, or 15 days from the date of separation, whichever comes first. The final paycheck covers wages you have already earned and must be paid by law. Severance is extra pay for leaving the job.
No Montana law requires severance, but if your contract or a written company policy promises it, you may be able to enforce that promise. An employer may offer direct deposit but may not require it, and the worker’s consent must be written or electronic and kept on record.
A paycard is allowed only if you agree to it and can get your full wages in cash or by check without unusual steps. If you never agreed to either, you may ask for a paper check.
Unused Vacation and PTO Under Montana Final Paycheck Law
Earned vacation is wages under the Act’s definition and is owed at separation (Langager v. Crazy Creek Products, Mont. 1998); the policy sets how it accrues. A policy cannot take away vacation the law treats as earned wages.
What the Montana Final Paycheck Law Does If the Check Is Late
The penalty is the lever: a penalty of up to 110% of the unpaid wages (39-3-206). Montana generally allows an employer to hold part of a final check only in one situation: the worker was fired over an allegation of work-related theft.
Even then, the employer must have the worker’s written agreement or must have filed a police report soon after the separation, and it may hold back only enough to cover the value of the alleged theft. Beyond deductions required by law or authorized by the worker, the state generally does not let an employer hold back final wages to cover business losses.
What Can Be Deducted From a Final Check in Montana
Montana generally allows deductions only when the law requires them, such as taxes or garnishments, or when the worker has agreed in writing to a deduction that benefits the worker. Reasonable charges for room and board provided as a condition of the job are also allowed.

Under department guidance, an employer generally may not take cash shortages, breakage, mistakes, or unreturned uniforms, keys, tools or equipment out of earned wages, even if the worker signed an agreement. Confirm the details with the state agency.
How to File a Wage Claim Under the Montana Final Paycheck Law
The state generally requires workers to file a written wage claim with the Montana Department of Labor & Industry’s Wage and Hour Unit. You can get the Wage Claim Form and instructions on the department’s website or at a Job Service office. You can also ask for one at [email protected] or 406-444-6543, then return it by email or by mail to PO Box 201503, Helena, MT 59620-1503.
Attach pay stubs, timecards and a short note showing how you worked out what you are owed. File within 180 days of the date the employer failed to pay or paid late.
The department notifies the employer and asks for a response. If the employer does not respond on time, the department may rule against the employer. The department then issues a determination of any wages and penalty owed. Either side may ask for one redetermination or for a hearing within 15 days. Hearing requests go to mediation first, and anything still unresolved goes to a contested-case hearing before a hearings officer.
If a claim is found valid and the employer does not appeal, the department may enter a default order. Yes. A Montana worker may sue for unpaid final wages in the small claims division of justice court for claims up to 7000, not counting court costs, under MCA 25-35-502.
Filing a department wage claim may count as choosing that route, which can prevent a separate suit over the same wages, so confirm the route with the state agency first.
Other Montana Final Paycheck Law Rules to Know
Montana is the only state that is not “at-will.” After an employee finishes the employer’s probationary period, the Wrongful Discharge from Employment Act (MCA 39-2-901 et seq.) generally requires good cause for firing. That is a separate claim from a final-pay claim, so a worker who was fired may want to confirm both rights with the state agency or an attorney.
Think your employer owes you money or broke the law?
You do not need a lawyer to file a wage claim: Montana Department of Labor and Industry, Employment Standards Division takes the complaint for free and can order the employer to pay. If the amount is large or the employer has a history, an employment attorney can take the case — the state bar referral service is the place to start.
