How to Hire Employees in Montana: The Complete Compliance Sequence

The first Montana employer I walked through a first hire had done everything a founder normally does. Job posted, candidate picked, offer letter sent, start date on the calendar. What he had not done was read the one paragraph of Montana law that makes his state different from all forty-nine others: after the probationary period ends, he needs good cause to fire that person, and if his offer letter says nothing about probation, the statute decides how long it lasts.

Montana is not a hard state to hire in. It has two state registrations rather than three, a twenty day new hire reporting window rather than a seven day one, and no local minimum wage anywhere in it. What Montana has instead is a small set of rules that behave nothing like their equivalents elsewhere, and every one of them lands in the first hire rather than years later.

I built FirstHR because this is exactly the kind of sequence a business without a dedicated HR person keeps dropping. The rules are learnable in an afternoon. Setting the reminder is the part that never happens. Below is the full Montana sequence in the order the work actually occurs, with the deadline and the exposure attached to each step, checked against the agency or the statute that governs it.

The Montana Hiring Sequence at a Glance

Every item below is a legal obligation with a named enforcing body and a stated consequence. Six of them land before you have a candidate in hand, three around the offer and the start date, and the rest inside the first month of employment.

The rest of this guide walks each step in the same order, calling out where Montana departs from the generic advice in a national guide to hiring your first employee. The broader picture, covering leave, termination and recordkeeping after the hire is complete, sits in the Montana compliance hub.

Step 1: Get Your Federal Employer Identification Number

Start with the federal Employer Identification Number, because both Montana registrations that follow ask for it on the identification screen. The EIN is how the IRS identifies your business on employment tax returns and deposits, and it is also the number a workers compensation carrier will want on the application.

If you formed an LLC or a corporation and already hold an EIN, reuse it. If you have been operating as a sole proprietor and filing under your Social Security number, you need one now. Payroll tax deposits cannot be made against a personal Social Security number, and none of the Montana accounts will open without a federal number attached.

Finish this before touching anything else. Founders who try to run the state registrations in parallel with the EIN application almost always restart one of them, because the state portals ask for the federal number at the beginning rather than at the end. Ten minutes here removes a dependency from three separate steps at once.

Step 2: Open Your Montana Income Tax Withholding Account

Montana has a state income tax, so the second step is registering with the Montana Department of Revenue for wage withholding. Registration runs through the TransAction Portal, where a new business selects the option to register for a new tax account. The number you receive identifies you on every Montana withholding return, and the department assigns the schedule on which you remit what you withhold.

Do this before the first payroll rather than after it. Withholding is a trust obligation: the money belongs to the state from the moment it leaves the paycheck, and late remittance carries penalty and interest even when the underlying calculation was perfect. The full Montana tax picture, including the current bracket structure and filing cadence, sits in the Montana payroll guide.

Two details save trouble later. Keep the Montana withholding account number and the federal EIN together, because Montana filings ask for both and the two numbers look nothing alike. And record the remittance frequency the department assigns you, since it decides whether your deposits run on a monthly or an annual rhythm. Guessing that frequency is the fastest way to turn a correct calculation into a late payment penalty.

Step 3: Open Your Unemployment Insurance Account

Unemployment insurance is a separate registration with a separate agency. You register with the Montana Department of Labor and Industry through UI eServices for Employers, and a first-time employer selects the new business registration option. The account number you receive is used on every quarterly wage report you file.

New employers do not pick their own unemployment contribution rate. Montana assigns a rate drawn from the average for the employer industry classification and recalculates it once your own claims history matures. An administrative fund tax of 0.18 percent sits on top of the contribution rate for new employers. What is fixed by rule rather than by industry is the base the rate applies to.

That base is the number to put in the budget. Montana sets the taxable wage base annually at 80 percent of the average annual wage, rounded to the nearest hundred dollars, and the Department of Labor and Industry set it at $47,300 for 2026 under rate Schedule 1. Contributions stop once an employee crosses the base, which front-loads unemployment tax into the early months of the year for a salaried hire and spreads it across more of the year for a part-time one.

Step 4: Put Workers Compensation Coverage in Force

Montana requires workers compensation insurance, and coverage is not elective. The Workers Compensation Act applies to all employers and all employees except for the employments the statute specifically exempts, and every covered employer has to elect one of the three compensation plans. An employer with an employee in service has no opt-out election available to it.

The exemptions are structural rather than size based, which is the part that misleads first-time employers. Sole proprietors, working partners and working members of a member-managed LLC fall outside the employee definition and may elect personal coverage if they want it. That says nothing about the person you are about to hire. Construction carries an extra rule at the state line: an employer from another state engaged in the construction industry gets no extraterritorial reciprocity and must obtain Montana coverage for the out-of-state workers it brings here.

Price the coverage before you finalize the wage. Premium is driven by payroll and by the classification code describing the work, so a ranch hand and a desk role at the same salary do not cost the same to insure. Getting a quote during the offer stage rather than the week before the start date keeps the total cost of the hire honest and removes the temptation to let the start date drift ahead of the binder.

Step 5: Check the Application, Then Write the Offer Carefully

Two things happen before an offer goes out in Montana, and the second one has consequences that outlast the hire by years. First, the application and the job ad have to line up with Montana protected classes. Second, the offer letter has to state the probationary period, because the statute will state it for you if you do not.

The Montana Human Rights Act reaches an employer of one or more persons, so there is no headcount runway before anti-discrimination law applies to you. Montana adds two protected categories that surprise employers arriving from other states. House Bill 702 makes vaccination status and possession of an immunity passport an unlawful basis for refusing employment or discriminating in any term of employment, with a narrow carve-out for a licensed health care facility that asks employees to volunteer their status and then implements reasonable accommodation measures. And a separate statute bars discrimination against a person for the use of a lawful product off the premises during nonworking hours, unless the use affects job performance or the safety of others or conflicts with a bona fide occupational qualification.

What Montana does not have is equally useful to know. There is no statewide ban-the-box statute reaching private employers and no salary history ban, so the sequencing rules that dominate hiring in coastal states do not apply here. A lawful background check still runs under federal fair credit reporting rules, and drug testing runs under a state act that limits testing to defined categories of work.

Write the wage, the payday and the probationary period into the offer letter in plain words. Montana does not fix a pay frequency by statute, but an employer may not withhold earned wages for longer than 10 business days after they become due, and a pay period is presumed to be semimonthly where no period has been established. Choosing the calendar explicitly is cheaper than inheriting a presumption.

Step 6: Verify Work Authorization Before the First Hour of Work

Montana added a state layer to work authorization that did not exist a few years ago. The Legal Employment and Government Accountability Act, passed as House Bill 226 and effective July 1, 2025, requires an employer to verify a new employee identity and legal ability to work in the United States before that person begins work. Guidance for employers is published by the Department of Labor and Industry on its LEGAL Act page.

You have two ways to satisfy it. Complete Form I-9 and retain the supporting documentation, or use E-Verify. The state law does not mandate E-Verify, which is the detail most summaries get wrong. What changed is who can ask to see your work: the department may audit employers at random and investigates complaints from the public, and the penalty structure escalates with repeat violations up to suspension of business licenses. Employers who act in good faith and comply with federal law are protected.

The federal timing rules are unchanged. The employee completes Section 1 of Form I-9 no later than the first day of work. You complete Section 2 within three business days of the start date by examining original documents the employee chooses to present. You may not tell the employee which documents to bring, and specifying documents is its own violation, separate from any deadline problem.

The reason this step deserves a calendar entry rather than a mental note is arithmetic. Federal civil money penalties are assessed per form and per employee rather than per audit, and paperwork errors get cited even when every worker turns out to be authorized. Add a state audit that can arrive at random, and the file you keep matters as much as the hire you made.

Step 7: Collect the Withholding Forms Before the First Paycheck

Montana has a state income tax, so a new hire completes two withholding forms rather than one. Federal Form W-4 sets federal withholding. Montana Form MW-4 sets Montana withholding, and the instructions direct a newly hired employee to complete it and give it to the employer, along with anyone claiming exemption from Montana withholding.

Collect both before day one rather than on day one. Everything on the list below except the employer half of the I-9 can be completed digitally in advance, which turns the first morning into an introduction to the work instead of an hour of forms. That sequencing is the whole point of structured new hire paperwork.

Step 8: File the New Hire Report Within Twenty Days

Montana gives you 20 days from the date of hire. The report goes to the Child Support Services Division at the Department of Public Health and Human Services, which runs the Montana New Hire Reporting Program, and the requirement sits in section 40-5-922 of the Montana Code Annotated. Rehires count as new hires.

Each report carries the employee name, date of hire and Social Security number, the residential and mailing addresses, and your business name, address and federal identification number. Date of birth and health or medical insurance eligibility are optional fields the statute invites but does not require. Employers who report electronically or magnetically may file twice a month instead, with the two transmissions spaced 12 to 16 days apart.

Twenty days feels generous next to states that allow seven, and that is precisely why it gets missed. A deadline three weeks out never feels urgent on the day the obligation arises, and by the time it does feel urgent the founder is three hires and one payroll run past remembering it. The data on the report is identical to what the W-4 already gave you, so the cost of doing it immediately is a few minutes.

Step 9: Post the Notices and Onboard Through Day 90

Two things happen at the start date. The required notices go up, and the actual onboarding begins. The notices are a one-time setup task. The onboarding is where the money you just spent on hiring either returns or evaporates.

Montana employers display both federal and state notices where employees can see them. The state set includes the minimum wage notice published each year by the Department of Labor and Industry, plus the unemployment insurance and workers compensation notices. Federal notices cover the Fair Labor Standards Act, occupational safety, the Employee Polygraph Protection Act and USERRA. Both governments publish their posters free, so there is no reason to buy a laminated set from a vendor.

Then comes the part with no deadline attached and the largest financial consequence. A structured first 90 days is what converts a signed offer into a productive employee, and it is the single element most likely to be skipped at a business without a dedicated HR person, because nothing external forces it to happen.

I built the AI onboarding wizard in FirstHR for exactly this stretch. The offer letter goes out with e-signature. The I-9, W-4 and MW-4 are collected digitally before day one. The system holds the reminders for the three business day I-9 deadline and the 20 day new hire report, and the wizard turns the job description into a 30-60-90 day plan instead of leaving the first quarter unplanned.

Montana Rules That Change How You Employ People

Six Montana rules reshape the employment relationship once the hire is complete. Each departs far enough from the national picture that copying a handbook or a pay policy from another state produces a compliance gap on arrival.

The wrongful discharge statute is the one that deserves the most attention, because it changes the default every other state gives you. At-will employment in Montana survives only through the probationary period. After that, a discharge that is not for good cause is wrongful, and so is a discharge that retaliates against an employee for refusing to violate public policy or for reporting a violation, one where the employer materially violated an express provision of its own written personnel policy in a way that cost the employee a fair chance to keep the job, or one based solely on the employee's legal expression of free speech.

Good cause is defined more generously than employers expect. It includes failure to satisfactorily perform job duties, a material or repeated violation of an express provision of the written policies, and other legitimate business reasons the employer determines in the exercise of reasonable business judgment. That definition is why the employee handbook is load-bearing in Montana rather than decorative: your written policies are simultaneously the source of your good cause and a document you can be held to for violating.

The wage floor is the rule that changes without anyone telling you. The Department of Labor and Industry reviews the state minimum no later than September 30 each year and adjusts it by the August over August change in the Consumer Price Index, rounded to the nearest five cents, with no change in a year the index does not rise. The current rate and the annual mechanics are published on the department state minimum wage page. Because there is no tip credit, a restaurant or bar labor model imported from another state has to be rebuilt before the first shift rather than after it.

Final pay is the second rule that trips out-of-state employers, and it runs the opposite direction from most states. A discharged employee must be paid immediately, defined as the earlier of the close of business or four hours from the moment the employee is told. A preexisting written policy can move that to the next regular payday or 15 calendar days, whichever comes first, but only if the policy was written first. An employer that gets the final paycheck wrong can owe the wages plus a penalty of up to 110 percent of the amount due.

City Requirements: Billings, Missoula and Bozeman

Montana is unusually simple at the city level. No Montana city or county sets a minimum wage above the state rate, so $10.85 per hour applies in Billings, Missoula, Bozeman, Great Falls and every unincorporated county alike. There is no local paid sick leave ordinance, no local scheduling law and no local hiring ordinance reaching private employers.

What does exist at the local level is nondiscrimination. A handful of Montana municipalities have adopted local ordinances that prohibit discrimination on the basis of sexual orientation and gender identity, and those ordinances reach employment alongside housing and public accommodations. Which cities those are is a question for the city clerk rather than the state, so confirm the ordinance text in any jurisdiction where you post a role.

The practical answer for a small employer is to write one policy set that already covers sexual orientation and gender identity and apply it across every Montana location. It satisfies any local ordinance, it costs nothing where none applies, and it removes the need to maintain two versions of a handbook because one office sits inside a city limit and another does not.

Remote arrangements are the one place this gets slippery, and the slipperiness runs across state lines rather than city ones. Employment obligations generally follow the place the work is performed, so a Montana business hiring someone who lives and works in another state picks up that state registration and leave rules rather than Montana ones. The reverse is also true: someone working from Missoula for an out-of-state company is a Montana employee for these purposes.

Employee or Independent Contractor: Montana Requires a Certificate

Montana handles worker classification differently from almost every other state, and the difference is procedural rather than philosophical. A person who regularly and customarily performs services at a location other than their own fixed business location must apply to the Department of Labor and Industry for an independent contractor exemption certificate, unless that person has elected to be personally bound by one of the state workers compensation plans. The statute defines that person as a sole proprietor, a working member of a partnership or a limited liability partnership, a working member of a member-managed LLC, or a manager of a manager-managed LLC engaged in construction work.

The certificate is not a formality you can skip because both sides prefer a 1099. To get one, the applicant swears and acknowledges two things: that they have been and will continue to be free from control or direction over the performance of their own services, both under the contract and in fact, and that they are engaged in an independently established trade, occupation, profession or business. The department charges a nonrefundable application fee of $125, and a person who holds a valid certificate is not required to carry a personal workers compensation policy.

Two consequences follow a reclassification, and employers usually anticipate only one. The unemployment side brings back contributions with interest and penalties for the whole period. The same facts also tend to produce a workers compensation coverage finding, because a person who was an employee for one purpose was an employee who should have been covered. That second exposure is frequently the larger of the two.

There is also a penalty aimed directly at certificate abuse. Working as an independent contractor after the department has suspended, revoked or denied a certificate, transferring a certificate to another person or using one that was never issued to you, altering a certificate, or misrepresenting contractor status all draw a departmental fine of up to $5,000 for each violation. The guidance is short: ask for the certificate number before the first invoice is paid, verify it, and file a copy with the contract. If the worker cannot produce one, the honest choice between an employee and a contractor has already been made for you.

The Mistakes That Cost Montana Small Businesses the Most

These are the failures that repeat at Montana businesses making a first or second hire. Each is a sequencing error or an imported habit rather than a knowledge gap. The employer knew the rule and ran the steps in the wrong order, or carried a template across a state line without reading it.

The common thread is that compliance fails on the calendar and in the template library, not in the reasoning. Nobody sets out to run an uninsured week or to shorten their own probationary period. The task simply arrives during a stretch when the founder is doing four other jobs, and the document that shapes it was written for somewhere else. That is why reminders, a Montana-specific offer letter and a task workflow do more good at this scale than another compliance summary would.
