Montana prices general liability about 29 percent above the national average and workers’ compensation about 43 percent above it. That makes it one of the dearer states for both, so a Montana business should budget above what the national guide shows. Below are the 2026 numbers by coverage, trade and headcount, what shapes them, and the levers that move a Montana premium. For the 50-state picture, see average business insurance cost by state.
Average business insurance cost in Montana by coverage
The table shows what a Montana business of two to five people in a middling risk class pays for the three policies most small businesses carry. Professional liability, also sold as errors and omissions, responds when a client says your work cost them money. A business owner’s policy adds property cover on your own equipment.
| Coverage | Typical monthly | Typical annual | What it covers |
|---|---|---|---|
| General liability ($1M per occurrence) | $39–$77/mo | $468–$924/yr | Third-party injury and property damage; the policy a client or landlord asks for by name. |
| Professional liability (E&O) | $97–$193/mo | $1,164–$2,316/yr | Claims that your advice or work cost a client money, legal defence included. |
| Business owner’s policy (BOP) | $64–$129/mo | $768–$1,548/yr | General liability plus commercial property, usually with business-interruption cover. |
| Hiscox advertised starting price | from $22.50/mo | from $270/yr | E&O from $22.50, general liability from about $29, a BOP from about $42. |

See these costs for your own business size, revenue and state
Most Montana businesses begin with general liability because somebody else demands it: a Billings landlord who wants a certificate before handing over keys, or a Bozeman property manager who will not let a cleaning crew into a building without one. A business owner’s policy earns its higher price once you own equipment, stock or a lease, because it bundles property cover for less than two separate policies. Our guide to general liability vs professional liability vs BOP explains which to buy first.
Montana business insurance cost by trade
Your trade moves the premium more than your address: a consultant who never leaves the laptop is a cheaper risk than a contractor, and insurers price that gap with a risk class. Twelve common trades in Montana, two to five people, $1M/$2M limits.
| Trade | General liability | Business owner’s policy |
|---|---|---|
| Consultant | $27–$55/mo | $47–$95/mo |
| IT or software developer | $32–$64/mo | $36–$71/mo |
| Accountant or bookkeeper | $26–$52/mo | $47–$93/mo |
| Photographer or videographer | $25–$50/mo | $36–$73/mo |
| Real estate agent | $28–$57/mo | $45–$90/mo |
| Online store | $36–$72/mo | $74–$148/mo |
| Personal trainer or fitness | $25–$50/mo | $46–$92/mo |
| Cleaning or janitorial | $41–$82/mo | $59–$118/mo |
| Landscaping or lawn care | $44–$88/mo | $73–$146/mo |
| Auto repair shop | $46–$93/mo | $116–$231/mo |
| Restaurant or café | $121–$242/mo | $195–$390/mo |
| General contractor | $139–$278/mo | $64–$129/mo |
Estimates from Insureon’s published medians for each business type for Montana, for two to five people at the standard $1M/$2M limits. Not quotes.
General contracting runs highest on this list because the work itself carries more injury and property-damage exposure than desk-based trades. Cleaning crews have their own guide: cleaning business insurance cost.
Cost by business size
Headcount matters too: every hire is another pair of hands that can drop a client’s server or leave a wet floor unsigned, and Insureon says more staff and more revenue generally mean higher premiums. It publishes no prices by headcount, so the table below only shows where in the Montana range a business of each size is likely to sit.
| Business size | General liability |
|---|---|
| Just me | $39–$58/mo |
| 2 to 5 people | $39–$77/mo |
| 6 or more people | $58–$77/mo |
Estimates from Insureon’s published medians for Montana, not quotes. No source publishes prices by headcount, so we show the lower half of the range for a one-person business under $100k in revenue, the whole range for two to five people, and the upper half for six or more. Larger businesses often pay more than this, especially for workers’ comp.
Business insurance cost in Billings, Missoula, Great Falls, Bozeman and Helena
Insurers price general liability and a BOP by state, not by city, so a Billings business and a Bozeman business pay the same $39–$77 a month for the same trade, size and limits. Montana’s statewide rate holds across its largest cities and towns.
| City | General liability | Local licensing office |
|---|---|---|
| Billings | $39–$77/mo | Billings, where a city business licence applies |
| Missoula | $39–$77/mo | Missoula, where a city business licence applies |
| Bozeman | $39–$77/mo | Bozeman, where a city business licence applies |
| Great Falls | $39–$77/mo | Great Falls, where a city business licence applies |
| Helena | $39–$77/mo | Helena, where a city business licence applies |
Same statewide Montana rate applies in every city; Montana has no city-level rating for general liability. Montana has no general state business licence, but cities and counties can require their own, so check with the city or county office.
Billings and Missoula, with Great Falls around them, hold most of the state’s small businesses, and Bozeman and Helena hold most of the rest, but none of them runs a higher rate than the others: Montana insurers price the whole state as one block.
Why Montana costs what it does
Montana’s general liability median is about 29 percent above the national one and its workers’ comp median is about 43 percent above it, so the state sits well above the national average on both.
- General liability above the country. Insureon’s Montana small business customers pay a median of $58 a month for general liability against $45 nationally, and a business owner’s policy, which includes it, runs higher too.
- Workers’ comp higher still. The Montana workers’ comp median in Insureon’s data is $77 a month against $54 nationally, so a business with employees pays noticeably more than it would in the typical state.
What Montana requires
The Montana Commissioner of Securities and Insurance regulates insurers. Workers’ compensation is generally required as soon as you have an employee, overseen by the Montana Department of Labor and Industry, and bought separately from the policies on this page. Confirm the exceptions that apply to your kind of work with the Department of Labor and Industry.
Construction trades are the other rule to know: Montana requires contractors to register with the Department of Labor and Industry, and construction trades should do that before they start work. Check what the state, your city and your county ask for, and what your clients ask for in insurance, before you start work.
How to lower your premium in Montana
Together these can move a Montana premium by a third or more.
- Get the classification right. A bookkeeper rated as a general consultant pays for a risk they do not carry, so describe the work precisely.
- Quote real revenue. Premiums scale with revenue, and quoting projections means overpaying until renewal.
- Buy the limits the contract asks for, not more. $1M/$2M satisfies nearly every Montana lease and vendor agreement; see $1 million liability insurance cost for what higher limits add.
- Bundle into a BOP. If you need property cover at all, a BOP is almost always cheaper than two separate policies.
- Stay claims-free and pay annually. Carriers price a clean loss history lower at renewal, and most charge less for one annual payment than for twelve.
Where these numbers come from
The figures at the top of this page and in the main cost table come from the same data as our cost estimator, so the two always agree. The starting point is the median premium that Insureon, an online insurance agency, publishes for its small business customers (see its Montana page). We adjust it for the state using Insureon’s state medians, and show the band that Insureon’s own price distribution says most businesses fall in. Every figure is an estimate, not a quote. The full method and source list is on the estimator page.
