Montana Workers’ Compensation Insurance

Every employer in Montana carries a legal duty to elect one of three ways to cover its workforce, and the statute does not count heads before it applies. Under MCA 39-71-401(1), a Montana employer must choose compensation Plan No. 1 (qualify as self-insured), Plan No. 2 (buy a policy from a private carrier), or Plan No. 3 (insure through the Montana State Fund). Montana workers’ compensation insurance is not a small-business exemption story the way many states run it: there is no minimum employee count that lets a Montana employer skip the election entirely. A defined list of exemptions carves out specific relationships instead, and knowing which list a business falls into, rather than counting payroll, is what actually decides whether coverage is required. That distinction sits at the center of Montana workers comp requirements for every employer in the state, whatever its size.

Who Is Covered, and Who Is Exempt

MCA 39-71-401(2) sets out the exemption list, and it runs longer than most employers expect: domestic employment in a private home, casual employment, sole proprietors and working partners who elect out for themselves, individuals paid solely on commission for selling securities, and several other narrow categories written directly into the section. None of them turn on headcount. The Montana legislature amended 39-71-401 again during its 2025 session, so an employer relying on last year’s reading of an exemption should not assume the current text still says the same thing; the exemption list needs to be rechecked against the current statute rather than against a prior filing year.

Independent contractor status in Montana is not something an employer creates simply by labeling a check as a 1099 payment. Coverage turns on whether the relationship actually fits one of the exemptions written into 39-71-401(2), including the sole-proprietor and working-partner elections, not on how the paperwork describes the arrangement. A worker who does not fit one of those listed carve-outs is inside the compensation system regardless of how the relationship is documented, and that payroll surfaces as uninsured exposure the moment an audit or a claim looks closely at it.

Montana also licenses professional employer organizations separately from the general employer duty. A PEO must show proof of Montana workers’ compensation coverage before the Department of Labor and Industry will issue its license, and it must then keep every leased employee covered under Title 39, chapter 8 (39-8-207(4)(c)). In a PEO arrangement, both the PEO and the client are treated as immediate employers for workers’ compensation purposes; in a straight employee-leasing arrangement, the leasing company alone carries the duty. Staffing and leasing arrangements bring their own layer of rules on top of this general threshold; see workers comp for staffing agencies in Montana for how those PEO and leasing distinctions play out for agencies placing workers across the state.

What Drives the Cost of Coverage

Montana premium is built the same way most states build it: a governing classification code assigned to the work actually performed, applied to reported payroll, then adjusted by an experience modification. NCCI serves as Montana’s designated advisory organization for classification and loss costs, and individual carriers may adopt those loss costs with or without their own deviation, so two carriers quoting the same classification code can still land in different places. Relative to other classes written in Montana, clerical and office work sits at the low end of the cost spectrum, general and light industrial work sits in the middle, and construction, logging, and other outdoor trades common to Montana’s economy sit at the high end, driven by injury frequency and severity rather than by payroll size alone. A mod above 1.0 multiplies manual premium upward regardless of classification, and it is usually a pattern of smaller claims, not one large loss, that pushes a mod out of a favorable range.

Penalties for Operating Without Coverage

Montana enforces the coverage duty mainly through the Uninsured Employers’ Fund. Under MCA 39-71-504, an employer caught operating without coverage is assessed the greater of double the Plan 3 premium it would have paid or $200, and a separate $200 penalty applies if the employer does not obtain coverage within 30 days of being notified. Unpaid amounts accrue $50 late fees plus interest at 12 percent a year. Part 5 of Title 39, chapter 71 attaches no general criminal penalty to the simple failure to insure. Criminal exposure only appears under MCA 39-71-507, and only where an employer defies a department order to stop operating: continuing to operate after a cease-operations order is a misdemeanor, and each day of continued defiance is charged as a separate offense.

Montana State Fund: The Named Backstop

Coverage under Plan 3 runs through Montana State Fund, and Montana State Fund is a guaranteed market. MCA 39-71-2313 requires it to insure any employer in the state who requests coverage, and it may not refuse a request except where the employer has an unsatisfied default on a prior obligation. Montana does not run a separate assigned-risk pool the way many states do; the State Fund itself is the backstop, sitting alongside Plan 1 self-insurance and Plan 2 private-carrier coverage as one of the three lawful ways to meet the 39-71-401(1) election.

Hard to Place in Montana

A guaranteed-issue state fund solves the access problem, not the price problem. An employer with a rising experience mod, a recent claim, or a classification that private carriers price cautiously can end up on Montana State Fund by default, simply because nobody shopped the account against Plan 2 markets first. NPN Brokers places accounts that standard carriers decline or price defensively, including businesses with elevated mods and thin loss history, through our high-risk workers’ comp program. Because Montana State Fund is a competitive Plan 3 option rather than a mandatory monopoly, a business currently sitting on the fund is free to leave the state fund for private coverage where a carrier’s terms come out ahead on the same risk. Seasonal and outdoor-trade employers whose payroll swings through the year can also ask about pay-as-you-go workers’ comp instead of funding a flat annual deposit, and businesses running payroll in Montana alongside other states can have us structure a single multi-state workers’ comp program instead of shopping each state separately.

Frequently Asked Questions

Who needs Montana workers’ compensation insurance?

Under Montana Code Annotated 39-71-401(1), every employer operating in the state must elect one of three coverage paths: Plan 1 self-insurance, Plan 2 coverage from a private carrier, or Plan 3 coverage through Montana State Fund, and no minimum employee count exempts a business from making that election. The specific exemptions written into 39-71-401(2), covering relationships like casual employment and sole proprietors who elect out, decide coverage, not the size of the payroll.

Which Montana employers are exempt from workers’ comp?

MCA 39-71-401(2) exempts domestic employment in a private home, casual employment, sole proprietors and working partners who elect out for themselves, and individuals paid solely on commission in specific sales categories, among other narrow carve-outs, none of which depend on headcount. The legislature amended this section in its 2025 session, so the current exemption list should be checked directly rather than assumed from a prior year’s filing.

What happens if a Montana employer operates without workers’ comp coverage?

Under MCA 39-71-504, the Uninsured Employers’ Fund assesses the greater of double the Plan 3 premium the employer would have paid or $200, plus a separate $200 penalty for not obtaining coverage within 30 days of notice, and unpaid amounts carry $50 late fees plus 12 percent annual interest. Part 5 of Title 39, chapter 71 carries no general criminal penalty for the simple failure to insure; criminal exposure only attaches under MCA 39-71-507, and only if the employer defies a department order to stop operating.

Is Montana State Fund the only place to buy coverage?

No. Montana employers choose among Plan 1 self-insurance, Plan 2 coverage from a private carrier, or Plan 3 coverage through Montana State Fund, and Montana State Fund is required under MCA 39-71-2313 to insure any employer that requests coverage, making it a guaranteed-issue option rather than the only option. A business already on the fund can shop Plan 2 private carriers and switch if the terms come out ahead.

How is Montana workers’ comp premium calculated?

Premium is built from a governing classification code applied to reported payroll and then adjusted by the employer’s experience modification, with NCCI serving as Montana’s designated advisory organization for classification and loss costs that carriers may adopt with or without deviation. Relative cost levels vary by trade, with clerical work at the low end and construction, logging, and other outdoor work at the high end of the range written in Montana.
