If you're running a business in Montana, there's one insurance policy you absolutely cannot skip: workers' compensation. Montana doesn't give you much wiggle room here—hire your first employee, and you're on the hook for coverage. No exceptions for small businesses. No grace period. Just a clear mandate that protects both you and your workers from the financial devastation of workplace injuries.

Here's the thing most Montana business owners don't realize until it's too late: workers' comp isn't just about following the law. It's about protecting yourself from personal financial ruin. Without coverage, you're personally liable for every medical bill, every dollar of lost wages, and every lawsuit that comes your way when someone gets hurt on the job. Let's break down exactly what you need to know.

Who Needs Workers' Compensation in Montana?

Montana's threshold is crystal clear: one employee. That's it. Whether you're hiring a full-time office manager or a part-time barista, the moment you bring on that first worker, you're required to carry workers' compensation insurance. This makes Montana one of the strictest states in the country—many other states allow small businesses to wait until they have three, four, or even five employees before coverage kicks in.

This one-employee rule applies across almost all industries. Whether you're running a construction company, a dental practice, a restaurant, or a retail shop, the law treats you the same. The state doesn't care if your employee works 40 hours a week or just 10—if they're on your payroll, they need to be covered.

That said, there are some exemptions. Sole proprietors working alone don't need coverage for themselves (though they can choose to buy it). The same goes for working members of partnerships, limited liability partnerships, and member-managed LLCs. Household or domestic workers and casual employees may also be exempt. But the second you hire someone who doesn't fall into these narrow categories, you're legally obligated to provide coverage.

How to Get Workers' Comp Coverage in Montana

Montana gives you three ways to comply with the law: buy coverage through Montana State Fund, purchase a policy from a private insurer, or self-insure with approval from the state.

Montana State Fund is the state's "insurer of last resort," which means they're required to offer coverage to any employer who requests it, regardless of how risky your business is. Established in 1990 as a non-profit independent public corporation, MSF operates in competition with private insurers but plays a unique role: they guarantee that every Montana employer can find coverage, even if private insurers turn them down. MSF is funded entirely through premiums and investment income—no taxpayer dollars—and currently offers some of the lowest rates in its history while distributing record dividends to policyholders.

Private insurers are the second option. Hundreds of insurance companies are approved to sell workers' compensation coverage in Montana, giving you plenty of choices if you want to shop around for rates and service. If you have a relatively safe workplace and a good claims history, you might find better deals in the private market.

Self-insurance is the third route, but it's generally limited to very large companies with the financial resources to handle claims directly. You'll need approval from the Montana Department of Labor and Industry's Employment Standards Division, and you'll have to prove you can cover potential claims without going bankrupt. Most small to mid-sized businesses stick with MSF or a private carrier.

Independent Contractors and Exemption Certificates

Here's where things get tricky for a lot of Montana businesses: independent contractors. If you hire an independent contractor who doesn't have their own workers' comp coverage, you might be on the hook for covering them under your policy—or they need to get an Independent Contractor Exemption Certificate.

The rule works like this: if an independent contractor regularly performs services at a location other than their own fixed business location, they must either carry their own workers' comp insurance or obtain an exemption certificate. For example, if you're a contractor who works at client job sites all over town, you need one of these two things. But if you're an attorney or CPA working from your own office on Main Street, you're generally not required to have an exemption or coverage.

There's a special rule for the trucking industry: all truckers, regardless of their business structure, must have either an exemption certificate or self-elected workers' comp coverage. No exceptions.

These exemption certificates are valid for two years and must be renewed to stay effective. Here's the catch: if you sign an exemption certificate, you're waiving your right to workers' comp benefits. If you get injured on the job while performing work specified on that certificate, you're not eligible for coverage. Both independent contractors and the businesses that hire them can be fined up to $5,000 per violation if they fail to comply with exemption certificate requirements.

What Happens If You Don't Have Coverage?

Montana doesn't mess around when it comes to enforcement. If you're caught operating without workers' comp insurance, you're looking at fines up to $1,000 plus an additional $100 for every day you're out of compliance. But that's just the beginning.

The state can also hit you with a penalty equal to double the premium you should have paid over the past three years, with a minimum penalty of $200. For serious violations, employers face fines up to $50,000, potential imprisonment, and business closure. And here's the part that really hurts: you become personally liable for all medical expenses and lost wages resulting from employee injuries. That legal shield that normally protects you from employee lawsuits? Gone.

If an employee gets hurt while you're uninsured, Montana's Uninsured Employers Fund may step in to pay their benefits—but then they'll come after you to recover every penny, plus interest. The financial consequences can be catastrophic, especially for small businesses operating on thin margins.

How to Stay Compliant and Protect Your Business

Staying compliant is actually pretty straightforward. Before you hire your first employee, get a workers' comp policy in place. You can start by getting quotes from Montana State Fund and a few private insurers to compare rates. Make sure you understand how your premium is calculated—it's typically based on your payroll and the risk level of your industry.

If you hire independent contractors, verify that they either have their own workers' comp coverage or a valid exemption certificate before they start work. Keep copies of these documents in your records. Don't assume someone is properly covered just because they say they are—ask for proof.

Review your policy annually to make sure your coverage still matches your business. If you've added new types of work or expanded into higher-risk activities, your premium might change. It's better to update your policy proactively than to discover you're underinsured when someone files a claim.

Finally, invest in workplace safety. Fewer injuries mean lower premiums over time, and some insurers offer discounts for businesses with strong safety programs. It's not just about compliance—it's about creating a workplace where people can do their jobs without getting hurt, and protecting your bottom line in the process.

Questions?

Frequently Asked Questions

Do I need workers' comp if I'm a sole proprietor with no employees?

+

No, sole proprietors working alone are not required to carry workers' compensation insurance in Montana. However, the moment you hire your first employee, coverage becomes mandatory. Some sole proprietors choose to purchase coverage for themselves even though it's not required, especially in high-risk industries.

What's the difference between Montana State Fund and private workers' comp insurance?

+

Montana State Fund is a non-profit state entity that must offer coverage to any employer who requests it, making it the insurer of last resort. Private insurers can be more selective about who they cover. MSF currently offers competitive rates and dividends, while private insurers might offer better deals if you have a clean claims history. You're free to shop both options and choose what works best for your business.

How much does workers' compensation insurance cost in Montana?

+

Costs vary widely based on your industry, payroll size, and claims history. High-risk industries like construction pay more than low-risk businesses like retail or office work. Your premium is calculated as a rate per $100 of payroll, so a roofer might pay $15-30 per $100 of payroll while an accountant might pay $0.50-2 per $100. Get quotes from both Montana State Fund and private insurers to compare.

What happens if an independent contractor I hire doesn't have an exemption certificate?

+

If you hire an independent contractor who works at locations other than their own fixed business location and they don't have an exemption certificate or their own workers' comp coverage, you could be held responsible for covering them under your policy. Both you and the contractor can face fines up to $5,000 per violation. Always verify exemption certificates or proof of coverage before allowing contractors to start work.

Can I be personally sued if an employee gets hurt and I don't have workers' comp?

+

Yes. Workers' comp insurance provides you with immunity from employee lawsuits related to workplace injuries—it's part of the "grand bargain" where employees give up the right to sue in exchange for guaranteed benefits. Without coverage, you lose that protection and become personally liable for all medical bills, lost wages, and damages. Employees can sue you directly, and the financial consequences can be devastating.

Do part-time employees need to be covered under workers' comp?

+

Yes. Montana law doesn't distinguish between full-time and part-time employees. If someone is on your payroll—even if they only work a few hours a week—they must be covered under your workers' compensation policy. The number of hours worked doesn't matter; what matters is the employer-employee relationship.
