Montana business license guide
Last updated: April 26, 2026
Montana business licensing is mostly local. Your city or county may require a business license, business tax license, safety inspection certificate, home occupation approval, or zoning review. The state may also require a business filing, assumed business name, tax account, eStop license, professional license, or employer registration.
The short answer
Montana does not use one single statewide general business license for every business. The Montana Small Business Development Center says local city and county offices provide business licensing in Montana, while the state provides professional licenses.
That does not mean you can skip the state. You may still need to register an LLC, corporation, limited partnership, or assumed business name with the Montana Secretary of State. You may also need a Montana Department of Revenue tax account, an eStop Business License for certain activities, a Department of Labor & Industry professional or contractor registration, or a local city or county license.
Montana business license facts to know first
| Question | Montana answer |
|---|---|
| Is there one statewide general business license? | No single state license covers every Montana business. Montana’s SBDC says local city and county offices provide business licensing, and the state provides professional licenses. |
| Where do LLCs and corporations register? | With the Montana Secretary of State Business Services, usually through the Business Filing Portal. |
| What does Montana call a DBA? | Montana uses the term Assumed Business Name. The Secretary of State describes it as a trade name or fictitious business name. |
| Does Montana have a general sales tax seller’s permit? | Montana Department of Revenue says Montana does not have a general-use sales tax. Some businesses still owe specific taxes or need special registrations. |
| What is eStop? | The eStop Business Licenses Program is a Montana licensing path for certain activities, such as retail food, nursery retail sales, landscape service, sod farmers, underground storage tanks, meters, scales, tobacco, vapor products, off-premise beer and wine, and lottery-related licenses. |
| Can a city still require a license? | Yes. Billings, Missoula, Bozeman, Helena, Great Falls, and other local governments use their own license, permit, zoning, and inspection rules. |
Quick start: what to check first
Start with the place where the business will operate. In Montana, local rules can matter as much as state rules.
- Pick your exact business location. Write down the city, county, and whether the business is home-based, mobile, online, storefront, office-based, or job-site based.
- Check the city first. If your business is inside city limits or will work inside a city, ask that city about business licensing, zoning, building, fire, and home occupation rules.
- Check the county if you are outside city limits. County health, planning, building, sanitation, and road rules may apply.
- Register the business entity if needed. LLCs, corporations, and some other entities file with the Montana Secretary of State. A sole proprietor using only the owner’s legal name may not need a Secretary of State entity filing, but local licenses may still apply.
- Register an assumed business name if needed. If you use a public business name that is not the legal name of the owner or entity, check Montana’s Assumed Business Name rules.
- Check Montana tax accounts. Montana does not have a general-use sales tax, but income tax, withholding, lodging, tourism, cannabis, tobacco, alcohol, natural resource, or other specific taxes may apply.
- Check eStop and professional licenses. Use eStop for covered license types and the Department of Labor & Industry for professional licensing, contractor registration, and unemployment insurance.
- Check federal requirements. Many businesses need an EIN from the IRS. Some activities also need federal permits, such as alcohol, firearms, transportation, aviation, or regulated food and drug activities.
Important: A Montana LLC filing is not the same thing as a city business license. A city business license is not the same thing as an eStop license. A resale certificate is not the same thing as a seller’s permit. Keep each layer separate.
Montana license layers: who handles what?
Most people get confused because several offices may use similar words. Use this table to separate the layers.
| Government layer | What it may handle | Montana examples |
|---|---|---|
| Federal | Federal tax ID numbers and federal permits for regulated industries | IRS EIN; federal alcohol, firearms, trucking, aviation, food, or drug rules when applicable |
| State | Entity filings, assumed business names, state tax accounts, professional licenses, certain industry licenses, unemployment insurance, contractor registration | Montana Secretary of State, Montana Department of Revenue, Montana Department of Labor & Industry, eStop Business Licenses |
| County | Health, sanitation, septic, road access, building, planning, local cannabis tax, and rules outside city limits | County health office or sanitarian review for retail food; county planning or building office where applicable |
| City or town | Business license, business tax, zoning, home occupation approval, building permits, fire review, signs, mobile vending, short-term rental registration | Billings business license, Missoula business license, Bozeman business license, Great Falls Safety Inspection Certificate, Helena business license |
| Private platform | Marketplace or payment processor rules | Etsy, Shopify, Amazon, delivery apps, booking platforms, payment processors, or insurance companies may ask for tax or license documents, but they do not replace government rules |
State registration, assumed names, and Montana tax accounts
Business entity filings with the Montana Secretary of State
If you form an LLC, corporation, limited partnership, limited liability partnership, or similar entity, start with the Montana Secretary of State Business Services. The state directs users to register a new business or maintain an existing registration through the Montana Business Filing Portal.
This filing creates or registers the legal entity with the state. It does not automatically clear city licensing, zoning, health, fire, building, eStop, tax, or professional licensing rules.
Assumed Business Name in Montana
Montana’s Secretary of State uses the term Assumed Business Name. The state describes it as a trade name or fictitious business name under which a business is conducted and presented to the public. It is not the legal name of the person or entity that owns the business.
A sole proprietor who does business only under the owner’s legal name may not need to register with the Secretary of State just to exist as a sole proprietorship. But if the owner uses an assumed name, the Secretary of State says the assumed name should be registered. State and local licenses may still be required.
Example: If Maria Lopez runs a business as “Lopez Cleaning,” she should check Montana’s Assumed Business Name rules. If she forms “Lopez Cleaning LLC,” the LLC filing is different from a city business license and different from any local home occupation approval.
Montana taxes and resale certificates
Montana is different from many states because the Department of Revenue says Montana does not have a general-use sales tax. That means many retail sellers will not find a normal statewide sales tax seller’s permit like they would in states with a general sales tax.
Montana still has business tax rules. The Department of Revenue says businesses pay income taxes based on how they are registered with the IRS, and businesses may also owe withholding, natural resource, or other miscellaneous taxes. Those specific taxes can include alcohol, cannabis, tobacco, tourism, lodging, rental vehicle, telecommunications, contractor’s gross receipts, health care facility, and other taxes depending on the activity.
If you buy goods for resale and an out-of-state vendor asks for a resale certificate, the Montana Department of Revenue points businesses to the Montana Business Registry Resale Certificate. The Department says not to file that resale certificate with the Department of Revenue. Give it to the out-of-state vendor. The vendor may accept it, but is not required to accept it.
Employer registration
If you hire employees, you may need several separate registrations. At the federal level, many employers need an EIN from the IRS. In Montana, employers may need wage withholding with the Department of Revenue and unemployment insurance registration through the Department of Labor & Industry.
The Department of Labor & Industry’s UI eServices for Employers portal lets employers register for unemployment insurance, file and pay quarterly UI tax reports, review claim requests, view correspondence, and communicate through secure messaging.
| Item | What it does | Where to start |
|---|---|---|
| LLC, corporation, or similar entity | Creates or registers a legal business entity with Montana | Montana Secretary of State Business Services |
| Assumed Business Name | Registers a trade name or fictitious name used with the public | Montana Secretary of State business structures page |
| Montana tax accounts | Handles income tax, withholding, and other activity-specific taxes | Montana Department of Revenue Business & Income Tax |
| Montana resale certificate | May help Montana businesses buy goods for resale from out-of-state vendors | Montana Department of Revenue sales tax guidance |
| Unemployment insurance employer account | Registers the employer for Montana unemployment insurance reporting | Montana UI eServices for Employers |
Montana eStop and industry licenses
Montana’s eStop Business Licenses Program is not a general license for every business. It is a state licensing system for covered license types. The Department of Revenue page says the program is now administered by the Department of Labor & Industry and can be accessed through the Department of Labor & Industry Citizen Portal.
The official eStop page lists covered license types such as:
- Traditional and Sports Bet Lottery
- Retail food
- Nursery retail sales
- Landscape service
- Sod farmers
- Underground storage tanks
- Measuring devices, such as meters
- Weighing devices, such as scales
- Tobacco products
- Alternative nicotine and vapor products
- Off-premise retail sales for beer and wine
Retail food needs early county health review
Retail food is a good example of why Montana licensing can be layered. The eStop page says a stand-alone retail food license is not available through eStop. It also says the county health office or sanitarian should be contacted early so the location can be reviewed and approved for retail food sales.
The same state page warns that a food business may also need a city business license, zoning approval, fire approval, or building code approval. For restaurants, food trucks, markets, packaged food sellers, and similar businesses, check the county health office and the city before you spend money on a lease, trailer, kitchen, or equipment.
Contractors and professional licenses
Montana professional and occupational licensing is handled through the Department of Labor & Industry’s professional boards. This can affect occupations such as plumbers, electricians, health professionals, real estate professionals, cosmetology-related occupations, and other licensed work.
Construction contractors have their own Montana rules. The Department of Labor & Industry says construction contractors with employees, incorporated contractors, and manager-managed LLCs fall under construction contractor registration. The Department has also announced that Montana’s contractor registration program is transitioning to a license program beginning January 1, 2026, while contractors should continue using the current application process until the state’s system is ready.
Independent contractors may also need to review Montana’s Independent Contractor Exemption Certificate rules if they are trying to work without workers’ compensation coverage. This is a workers’ compensation issue, not a general city business license.
Do not assume eStop covers your city license. A Montana eStop license may satisfy one state license type, but it does not automatically replace city licensing, county health approval, zoning, fire review, building permits, or federal permits.
City, county, zoning, and home-based rules
Montana local governments do not all use the same words. One city may call the local requirement a business license. Another may use a safety inspection certificate, home occupation certificate, special business license, or business tax process.
Check the city if you operate inside city limits
If your business is inside a city, works inside a city, sells at events inside a city, rents commercial space inside a city, or serves customers inside a city, check that city’s license office before opening.
For example, Billings says any person who conducts business in the City or is based in the City must obtain a business license before the business starts. Billings also says the license shows the annual tax for doing business within the incorporated area and that other permits may still be required.
Missoula says most businesses located or operating in city limits need a business license. Missoula also states that state registration is a separate process from the city business license.
Check the county if you are outside city limits
If your business is outside city limits, the county may still matter. County health departments, sanitarians, planning offices, building departments, septic offices, road departments, and local cannabis tax rules may apply depending on your business.
Home-based businesses still need local review
Running a business from home does not always remove the license requirement. Billings says home businesses require a business license and must comply with the city zoning ordinance. Missoula says businesses physically located within city limits, including web-based businesses, must obtain a city business license unless an exemption applies and is approved.
Home occupation rules may limit customer visits, employees, signs, parking, noise, deliveries, outdoor storage, equipment, or hazardous materials. If you rent, also check your lease. If you live in an HOA or condominium, check private rules too.
Montana city examples
These examples show why a Montana state guide cannot give one local answer for every business. Use them as starting points, then confirm your exact address and business activity with the local office.
Billings
The City of Billings says any person who conducts business in the City or is based in the City must obtain a business license. Billings also says home businesses need a business license and must comply with zoning.
Missoula
The City of Missoula says most businesses located or operating in city limits need a business license. It uses several license types, including general business, contractor, itinerant vendor, rental, cannabis, liquor, and short-term rental-related registrations.
Bozeman
The City of Bozeman says business licenses are required for occupations, professions, enterprises, and establishments conducted for private profit or benefit on premises in the city, unless exempted by state law or city code.
Great Falls
Great Falls uses the term Safety Inspection Certificate for many business-license situations. Its city materials also refer to home occupation certificates and special business licenses.
Helena
Helena offers Civic Access for business, liquor, pet, planning, zoning, building, and inspection-related applications. Its general business license materials say commercial enterprises operating within city limits must obtain a business license.
Butte-Silver Bow
Butte-Silver Bow provides a starting-a-business page with local, state, and federal resources. Businesses should still confirm licensing, zoning, building, health, and tax steps for the exact activity and location.

Common mistakes to avoid in Montana
- Thinking an LLC is the license. A Montana LLC filing creates a business entity. It does not automatically approve the business location or local license.
- Skipping the city because there is no statewide general license. Montana’s licensing pattern is heavily local. Cities may have their own business license or tax process.
- Using the wrong name term. Montana uses “Assumed Business Name” for what many people call a DBA, trade name, or fictitious name.
- Looking for a normal sales tax seller’s permit. Montana does not have a general-use sales tax, but some businesses still have tax accounts or special tax rules.
- Opening a food business before health review. Retail food may require county sanitarian review, eStop steps, zoning, fire, building, and city licensing.
- Assuming online businesses have no local rules. If the business is operated from a Montana home or office, local zoning or business licensing may still apply.
- Assuming one city license works statewide. Billings specifically warns that each city has its own business license requirements. Check each city where you conduct business.
- Ignoring contractor and workers’ compensation rules. Construction, handyman, and independent contractor issues may involve Department of Labor & Industry rules, insurance, registration, or exemption certificate questions.
What to ask when you contact the agency
Before calling or emailing, write down your business type, legal name, assumed business name, exact address or service area, city, county, whether customers visit you, whether you work from home, whether you sell food or regulated products, and whether you will hire employees.
Phone or email script
Hello, I am trying to confirm the licensing steps for a [business type] in [city] and [county], Montana. The business will be [home-based / mobile / storefront / online / job-site based] at or near [address or general location]. We plan to provide [products or services]. Can you confirm whether we need a local business license, zoning approval, home occupation approval, health review, building or fire approval, state eStop license, tax account, or another permit before we start? If your office does not handle this, which office should I contact next?
If you are contacting the Secretary of State, ask about entity filing and assumed business name rules. If you are contacting the Department of Revenue, ask about tax accounts and activity-specific taxes. If you are contacting a city or county, ask about the exact address and the exact activity.
- Write down the agency name and the person or department that answered.
- Write down the date of the call or email.
- Ask for the exact license, permit, registration, or approval name.
- Ask for the official application link or form name.
- Ask whether zoning, fire, building, health, or county review is required before approval.
- Ask whether renewal, inspection, insurance, bond, background check, or display rules apply.
- Ask whether the answer changes if you move, add a location, hire employees, sell online, or change services.

FAQ
Does Montana have a statewide general business license?
Montana does not use one statewide general business license for every business. The Montana SBDC says local city and county offices provide business licensing in Montana, while the state provides professional licenses. Some businesses still need state registrations, eStop licenses, tax accounts, or local city or county approvals.
Is an LLC the same thing as a Montana business license?
No. An LLC filing with the Montana Secretary of State creates or registers a legal entity. It does not automatically give you a city business license, zoning approval, health permit, eStop license, professional license, tax account, or federal permit.
What is an assumed business name in Montana?
An assumed business name is Montana’s term for a trade name or fictitious business name used with the public. It is not the legal name of the person or entity that owns the business. If you use a public business name that is different from the legal owner name, check the Montana Secretary of State’s assumed business name rules.
Does Montana have a seller’s permit?
Montana does not have a general-use sales tax, so many businesses will not use a normal statewide sales tax seller’s permit. Montana businesses may still need tax accounts for income tax, withholding, lodging, tourism, alcohol, tobacco, cannabis, natural resources, or other specific taxes. Montana also has a Business Registry Resale Certificate for some resale situations with out-of-state vendors.
Do I need a city business license in Montana?
You may need one if your business is located in a city, works in a city, sells in a city, rents commercial space in a city, or serves customers in a city. Montana cities set their own local rules, so check the city where the business will operate.
Do home-based businesses in Montana need a license?
They may. Home-based businesses still need to check city or county business licensing and zoning rules. Some cities require a business license for home-based businesses and may also limit customer visits, employees, parking, signs, noise, storage, or deliveries.
Where do Montana employers register?
Many employers need a federal EIN from the IRS. In Montana, employers may also need wage withholding with the Montana Department of Revenue and unemployment insurance registration through the Montana Department of Labor & Industry’s UI eServices for Employers.
What is eStop in Montana?
eStop is Montana’s licensing program for certain state license types. It can cover activities such as retail food, nursery retail sales, landscape service, sod farming, underground storage tanks, scales, meters, tobacco, vapor products, off-premise beer and wine, and lottery-related licenses. It does not replace every city, county, state, or federal requirement.
