When you want to confirm that a company name is free, verify that a Montana LLC is in good standing, or pull up the registered agent behind a business, the answer lives in one free public database run by the Montana Secretary of State. This guide walks you through it from the first click to the final document download.
It is written for two audiences: people researching an existing Montana entity (due diligence, vendor checks, a name conflict), and founders who plan to register their own Montana LLC. If you are in the second group and based outside the US, the non-resident section below is for you.
Key Montana business search terms
Before you search, it helps to know the vocabulary the portal uses. These terms appear throughout your results.
| Term | What it means in Montana |
|---|---|
| Active / Good Standing | The entity is properly registered, current on filings, and legally able to operate. |
| Entity Number | The unique ID the Secretary of State assigns to every registered business. Faster than name for an exact lookup. |
| EIN vs. Entity Number | The EIN (Employer Identification Number) is a federal tax ID from the IRS. The entity number is a state ID. They are different things and not interchangeable. |
| Articles of Organization | Montana's formation document for an LLC. Filing it with the state creates the company. |
| Registered Agent | The person or company with a Montana physical address who receives legal and state mail on the entity's behalf. Required for every Montana entity. |
| Annual Report | The yearly filing that keeps an LLC active. Due between Jan 1 and April 15. |
| Certificate of Good Standing | Also called a Certificate of Existence. Official proof the entity is current and in compliance. Often requested by banks and partners. |
| Name Availability | Whether your desired company name is distinguishable from every existing Montana entity. |
| Inactive / Dissolved | The entity is no longer registered, voluntarily or by state action. |
What is the Montana business entity search tool?
The tool is the Montana Secretary of State's business search portal, hosted at biz.sosmt.gov/search/business. It is the single authoritative source for the public record of every LLC, corporation, partnership, and nonprofit registered in the state.
The search is completely free and requires no account. You can run unlimited searches, view an entity's status and registered agent, and open its filing history without logging in. You only need an account if you intend to file something, such as forming a new company or submitting an annual report. For pure lookup work, anyone, anywhere, can use it.
When to use it
A Montana entity search answers more questions than most people expect. Common reasons to run one:
-
Checking name availability before you register, so your chosen name is not rejected for being too similar to an existing one.
-
Confirming an entity's status to verify a company you are about to do business with is active and compliant.
-
Looking up a registered agent when you need to serve legal documents or send formal notice.
-
Due diligence on a supplier, partner, acquisition target, or counterparty.
-
Finding an entity number you need for a filing, a bank form, or a government application.
-
Pulling filing history to see when a company was formed and what documents it has on record.
Step-by-step guide
Step 1 , Open the portal. Go to biz.sosmt.gov/search/business. No login is needed for searching.
Step 2 , Choose your search method. You can search by business name or by entity number. If you know the exact name, type it in. If you only know part of it, use a keyword or partial term and let the results list narrow things down. Searching by entity number returns a single exact match, which is the cleanest route when you have it.
Step 3 , Use Montana-specific search tips. Montana name results match on the distinguishable part of a name, so a search for "Glacier" will surface "Glacier Holdings LLC," "Glacier Peak Trading," and similar entries. Drop the entity ending (LLC, Inc, Corp) from your search term to widen results, then scan the list. Spelling variations matter, so try one or two alternatives if your first search comes up empty.
Step 4 , Read your results. Each result shows the entity name, type, status, and registration date. Click an entry to open its full record, where you will find the entity number, the registered agent and address, the formation date, and the filing history.
Step 5 , Access and download documents. From the entity's record you can view and download filed documents such as the Articles of Organization and past annual reports. Plain copies are free to view. If you need a certified copy or an official Certificate of Good Standing for a bank or legal use, that is ordered separately through the Secretary of State as a paid service.
Montana entity status definitions
The status label on a result tells you whether a company is healthy. Here is what each one means.
-
Active / Good Standing , Registered, current on filings, and legally able to operate. This is the status you want to see.
-
Delinquent , The entity missed its annual report deadline. It still exists but is out of compliance and at risk of involuntary dissolution if the lapse continues.
-
Inactive / Dissolved , No longer registered. This can be voluntary (the owners closed it) or involuntary (the state dissolved it after a prolonged failure to file). A dissolved entity can sometimes be reinstated.
-
Pending , A filing has been submitted but not yet fully processed by the state.
If a name you want is attached to a dissolved or inactive entity, it may become available again, but confirm with the Secretary of State before you rely on it.
Montana-specific quirks and tips
Montana has a handful of features that make it distinct from larger formation states, and they are exactly why founders choose it.
-
One of the lowest filing fees in the country. The Articles of Organization cost just $35 to file. Few states are cheaper.
-
The annual report fee is currently waived. Montana normally charges $20 for the LLC annual report, due between January 1 and April 15. For 2024, 2025, 2026, and 2027 the Secretary of State has waived that fee for reports filed on time, so the report is effectively free right now. You must still file it; only the fee is waived. File after April 15 and a $35 late fee applies. Reinstatement, if you lapse, is $35.
-
No general state sales tax. Montana is one of a small group of states with no statewide sales tax, which simplifies life for certain business models.
-
State income tax applies only to Montana-sourced income. Montana levies income tax on income earned from Montana activity. A non-resident-owned LLC with no Montana operations, employees, or in-state customers generally has no Montana income tax exposure. This is a general rule, not a guarantee for your situation, so confirm with a tax advisor.
-
Member privacy. Montana's public record centers on the registered agent and the entity, not a full roster of every member, so ownership is not broadcast the way it is in some states.
-
Simple compliance. A single yearly report inside a fixed window is the core ongoing obligation. There is no franchise tax of the kind that catches founders off guard in larger states.
The honest trade-off: Montana carries less brand recognition and a less developed body of business case law than Wyoming or Delaware. For a holding company, a low-cost vehicle, or a founder who values low fees and simplicity, that trade is often worth it. For a venture aiming to raise institutional capital, Delaware is usually still expected.
What to do if the name is available , or taken
If the name is available: you have two paths. You can reserve it through the Secretary of State to hold it while you prepare your filing, or you can simply form the entity and lock the name in immediately by filing the Articles of Organization for $35. For most founders ready to proceed, forming directly is the cleaner move.
If the name is taken: check the status of the entity holding it. If that entity is dissolved or inactive, the name may be available again. If it is active, you will need to modify your name so it is distinguishable, choose a different entity type, or consider operating under an assumed business name (DBA) while keeping a distinct legal name. A name that is merely similar in concept but distinguishable in wording will usually clear.
Montana business entity search for non-US founders
If you live outside the United States, the Montana search works for you exactly as it does for anyone else. The portal is public, free, and has no requirement to log in, hold a US address, or be a US citizen to run a search. You can check name availability and research entities from any country.
Montana also allows non-residents of any nationality to own a Montana LLC, with no requirement to visit the US to form one. Combined with the $35 filing fee, the currently waived annual report fee, and no general sales tax, that makes Montana an attractive low-cost base for international founders running holding companies, e-commerce stores, SaaS, and consulting businesses serving customers outside Montana.
The two practical hurdles for non-residents are not the search; they are getting an EIN without an SSN and opening a US bank account from abroad. Bastion handles both. We obtain your EIN with the official IRS CP-575 confirmation letter even without a Social Security number, and we guide you through US bank account setup. Form your Montana LLC from $249 →
