How to Form a Montana LLC — Step by Step

Follow these steps to form your Montana LLC yourself. Each step includes links to the official state resources you'll need.

1Search for Name Availability

Go to the Secretary of State — Business Services search tool. Enter your desired LLC name (excluding "LLC" suffixes) to check availability. The name must be distinguishable from other registered entities in Montana.

If your desired name is available, you can proceed directly to filing. Optionally, you can file a name reservation if you are not ready to file immediately.

Make sure to verify if the domain name is available and search the USPTO trademark database to prevent any trademark issues later.

2Choose a Registered Agent

Every LLC in Montana is required to have a registered agent. A registered agent is a person or entity authorized to receive service of process and official state mail on behalf of your company.

Your registered agent must have a physical street address in Montana (P.O. boxes are not allowed) and be available during regular business hours. You can act as your own agent if you reside in the state, or hire a professional service.

Using a professional registered agent service keeps your home or business address off the public record, enhancing your privacy.

3File Articles of Organization

To officially register your LLC, you must file the Articles of Organization (sometimes called Certificate of Organization or Certificate of Formation) with the Secretary of State — Business Services.

The filing fee is $70. Complete the filing documents and submit them by mail along with the state fee as a check or money order.

Review all information carefully before submitting. Errors in spelling or addresses can delay approval or require costly amendment filings.

4Draft an Operating Agreement

An Operating Agreement is an internal document that outlines the ownership structure, member roles, capital contributions, voting rights, and profit distributions of the LLC.

Although Montana does not require you to file the operating agreement with the state, having one is highly recommended to establish clear rules, maintain personal liability protection, and open business bank accounts.

Even single-member LLCs benefit from an operating agreement, as it demonstrates that the entity operates independently from the owner's personal affairs.

5Obtain an Employer Identification Number (EIN)

An EIN is a federal tax ID issued by the IRS, similar to a Social Security number for your business. You will need it to hire employees, open a business bank account, and file federal taxes.

You can apply online for free on the IRS website. The application takes only a few minutes, and the EIN is issued immediately upon completion.

Never pay a third-party service to get an EIN. It is a free, quick service provided directly by the IRS.

6Open a Business Bank Account

Once your LLC is approved and you have an EIN, you should open a dedicated business checking account. Take your approved Articles of Organization, EIN confirmation letter, and operating agreement to the bank.

Keeping your personal and business finances strictly separated is critical to preserving the personal liability shield provided by your LLC.

Shop around for business banking accounts that offer low monthly fees, digital integrations, and convenient deposit options.

7Register for State Taxes

Depending on your business activities, you may need to register for state taxes. If you sell tangible goods, you will likely need to register for sales tax. If you hire employees, you must register for state withholding and unemployment taxes.

Montana has no sales tax. Individual income tax rates range from 1–6.75%. Corporate income tax 6.75%. Montana is one of only five states with no sales tax.

LLCs are pass-through entities by default, meaning business profits pass to the owners' personal tax returns. Consult a CPA to understand your specific state tax requirements.

8Understand Ongoing Compliance Requirements

To keep your LLC in good standing, you must comply with annual or biennial reporting requirements in Montana.

Your annual/biennial report is due by April 15 with a filing fee of $15.

Mark your calendar for compliance deadlines. Missing deadlines can lead to late fees and the potential suspension or dissolution of your LLC.
