Starting a business in Montana can be exciting, especially if you already have a solid idea and know who you want to serve. But before you make your first sale, there are a few practical things to take care of.
Selecting a business structure, registering the company, verifying licenses and permissions, comprehending your tax obligations, and establishing a financial management system are all necessary. You can avoid needless problems in the future by following these instructions in the correct order.
Montana lets entrepreneurs complete many business filings online through the Secretary of State’s business portal. The state also has an eStop system that brings several licensing and permitting services together in one place.
Here is a straightforward look at how to start a business in Montana in 2026.
1. Choose a Business Idea
Start with the company, not the paperwork.
Consider your target market, what you intend to sell, and how the company will generate revenue. Building a firm that aims to serve everyone is frequently more difficult than developing a straightforward concept with a defined target market.
You should also check your competition. Look at what similar businesses charge, where they operate, and what customers like or dislike about them.
Once you have a clearer idea of the market, you can move on to the legal side of the business.
2. Select the Right Business Structure
How you register the business, handle taxes, and determine your potential level of personal culpability are all influenced by your business structure.
A corporation, LLC, partnership, or sole proprietorship are typical options. A sole proprietorship may be a more straightforward choice for an individual owner, but an LLC is frequently taken into consideration by owners who need a formal business entity with liability protection.
Here is a basic comparison:
| Business structure | Common fit | Main thing to consider |
| Sole proprietorship | One person running a small business | Owner and business are not separate for liability purposes |
| LLC | Small businesses wanting a separate legal entity | Requires state registration and ongoing compliance |
| Partnership | Two or more owners | Partners share responsibility under the chosen partnership arrangement |
| Corporation | Businesses planning a more formal structure | More administrative requirements and formalities |
The best structure depends on your business, finances, ownership plans, and risk level. It is worth getting professional advice before making the final choice.
3. Choose and Check Your Business Name
Your business name should be easy to remember and appropriate for what you do.
Before settling on one, check whether the name is available through the Montana Secretary of State. You should also think about your website domain and social media handles.
The Montana Secretary of State provides an online filing portal where businesses can register and maintain their records.
Do not rush this part. Changing a business name after you’ve built your branding around it can be frustrating and expensive.
4. Register Your Business in Montana
Once you have chosen the structure and name, it is time to register the business.
Montana’s Secretary of State says registrations can be completed through its online filing portal. You create an account, select the appropriate form, complete the required information, pay the filing fee, and wait for the filing to be reviewed. Once approved, the state sends an email with access to the approved documents.
The filing fee depends on the entity type, so check the current Montana fee schedule before submitting your application.
5. Decide Whether You Need an Assumed Business Name
A sole proprietor may operate under their own legal name. However, if you want to use a different business name, Montana allows registration of an Assumed Business Name (ABN), also known as a DBA.
The Secretary of State currently lists the ABN registration fee at $20, with renewal required every five years.
This can be useful when your public-facing business name is different from your personal name.
6. Get an EIN from the IRS
After forming your business, determine whether you need a federal Employer Identification Number, or EIN.
An EIN is commonly used for business tax purposes, hiring employees, and opening certain business accounts. Whether you need one depends on your business structure and circumstances.
Keep your federal and state records together. Having organized documents from the beginning makes tax and banking tasks much easier.
7. Check Business Licenses and Permits
Registering your business with the state does not automatically give you permission to operate every type of business.
Montana’s Secretary of State notes that some businesses may need additional state or local licenses. Certain professions are regulated by the Montana Department of Labor & Industry, while some industries can use the state’s eStop Business License system. Cities and counties may also have their own requirements.
Retail food, landscape services, weighing and measuring equipment, alcohol-related permits, and some other regulated activities are currently covered under Montana’s eStop program.
This is one area where your location and industry matter a lot.
8. Register With the Montana Department of Revenue
State registration is only one piece of the setup.
Montana’s Department of Revenue explains that business tax obligations depend on how the business is registered for federal tax purposes. Businesses may have corporate income tax, pass-through tax obligations, withholding requirements, or other state taxes depending on their situation.
Businesses registered with the Secretary of State should also take care of the applicable Department of Revenue registration requirements.
Your tax setup should match your actual business structure and activities, so this is a good point to speak with an accountant if you are unsure.
9. Understand Montana Business Taxes
Montana has several business-related tax areas, and the rules are not identical for every business.
For example, pass-through entities can include partnerships, S corporations, and LLCs taxed as partnerships or S corporations. The Department of Revenue says these businesses may have Montana tax liabilities even though the income generally passes through to the owners for federal income tax purposes.
Businesses may also need to handle employee withholding or other taxes depending on what they do.
Rather than assuming your business has one simple tax obligation, identify every tax that applies to your structure and activity.
10. Open a Business Bank Account
Once your business is properly established, keep business finances separate from personal spending.
A dedicated business bank account makes it easier to track sales, expenses, taxes, payroll, and other transactions. It also gives you a clearer picture of how the business is actually performing.
You may need your formation documents, identification, and tax information when applying for the account.
11. Get the Right Insurance
Insurance is another part of running a business that should not be pushed aside.
The type of coverage you need depends on your industry. A contractor, restaurant, consultant, retailer, and online business can all have very different risks.
Consider areas such as general liability, professional liability, commercial property, or workers’ compensation where applicable.
The goal is simple: make sure one unexpected event does not put the whole business at risk.
12. Set Up Accounting From the Start
You do not need an elaborate accounting system on day one, but you do need a reliable one.
Track your income and expenses from the beginning. Save receipts, keep invoices organized, and set aside money for taxes instead of waiting until a payment is due.
If you hire employees, your bookkeeping becomes even more important because payroll and withholding need to be handled correctly.
Good records also make it easier to see whether your business is actually making money.
13. Remember Your Annual Report
Starting the business is one thing. Keeping it in good standing is another.
Montana requires annual reports for LLCs and corporations. The Secretary of State says annual reports are used to keep registration information current. For domestic entities, the annual report deadline is December 1. The filing fee is waived for reports filed between January 1 and April 15; after April 15, the listed fee is $35.
Put the deadline on your calendar every year. Missing routine filings can create avoidable problems.
14. Build Your Business After the Legal Setup
Once the legal and financial basics are handled, you can focus on growth.
Create a simple website, establish your social media presence, set up a way for customers to contact you, and make sure your pricing covers your real costs.
You do not need a huge marketing budget to get started. Concentrate on finding your first customers and learning what they actually value.
As the business grows, you can expand your products, bring on employees, improve your systems, or open another location.
How Much Does It Cost to Start a Business in Montana?
There is no single startup cost for every Montana business.
The state filing fee, business-name registration, licenses and permits, insurance, professional services, equipment, rent, website expenses, and inventory may all be included in your overall expenditure.
For example, the Montana Secretary of State currently lists $20 for an Assumed Business Name registration, while entity registration fees vary depending on the type of business.
The easiest way to budget is to separate your expenses into two groups: costs required to legally open the business and costs needed to actually operate it.
