Montana Secretary of State business search — LLC name check, trademark & domain lookup
Montana's $35 LLC filing is the lowest in the nation, and the state's registry has grown fast with out-of-state owners registering vehicles through Montana LLCs. That means the pool of 'Big Sky', 'Mountain' and 'Glacier' names is far deeper than the population suggests — check the exact phrasing, not just the idea.
Is it taken in Montana? — Enter the name exactly as you'd file it; the Montana registry, USPTO and domain registrars are checked together.

- Check the name as you'd file it. With the designator (LLC) attached — Montana compares the whole string.
- Verify at the source. The official Montana Secretary of State search is the record that counts; registrations change daily.
- Don't stop at the state line. A clear Montana result says nothing about federal trademarks or the domain; the checker covers both in the same run.
Montana naming rules: what the Montana Secretary of State will and won't accept
The rule that matters most in Montana is distinguishable on the records of the Secretary of State. Swapping 'Inc.' for 'LLC', adding 'The', or changing a comma does not make a name distinguishable here. An LLC name must end in LLC, L.L.C., Limited Liability Company and Limited Company; a corporation uses Corporation, Corp., Incorporated and Inc., among others.
Certain words trigger a review. In Montana that list includes Bank, Trust, Insurance, Engineer and Cooperative — using one implies a regulated activity and the filing will be held until the relevant regulator consents.
The fees are straightforward: forming an LLC costs $35, a corporation $70 and a name reservation is $10 and holds the name for 120 days. Online filings usually 1-3 business days.
After you file: Annual report, $20, due April 15. Skip it and the state eventually dissolves the entity, releasing the name back into the pool.
As published by the Montana Secretary of State, (406) 444-3665 — fee schedule. Fees change; confirm before filing.
How busy is Montana right now?
Businesses in Montana filed 32,518 new business applications in the twelve months to August 2026 — +15.1% on the year before, the 40th-highest total of any state and 28.6 per 1,000 residents (ranked 4th per person). April was the busiest month with 3,325 applications, and Montana accounts for 0.5% of all U.S. filings.
That volume is the reason exact-name checks age quickly here: the registry changes by the hundreds every business day.

The four tests a Montana business name has to pass
1. Nobody active already has it. The Montana Secretary of State compares your name against every entity currently on its books; a company that was dissolved or had its registration revoked normally doesn't count, although one that lapsed only recently could be reinstated — the checker calls that out when it sees it.
2. It's genuinely different, not just formatted differently. "Distinguishable" in Montana means more than a comma, an ampersand, a plural or a different suffix. Sound-alikes and spell-alikes are the usual reason a filing bounces.
3. It carries the right designator. An LLC's legal name has to end in an LLC designator; a corporation needs Inc., Corp., Company or another form Montana accepts. The designator is part of the name the state records.
4. It doesn't step on a trademark. The registry doesn't look at the USPTO, so a name can clear Montana and still be a federal infringement. That is why the trademark check runs alongside the registry search here.

Before you file in Montana: a two-minute double check

- Repeat the search on the official Montana lookup, spelling the name exactly as it will be filed, with the designator.
- For every match returned, note the status. Active blocks; dissolved or revoked usually doesn't; a recent lapse deserves a second look.

- Clear on both? Reserve or file straight away. Names are first-come, first-served.
Frequently asked questions
- Does a Montana registration protect my name in other states?
- No. It protects the name inside Montana's registry only. Nationwide protection comes from a federal trademark, which is why the checker runs the USPTO search alongside the Montana lookup.
- What does a Montana LLC name have to end with?
- One of the state's accepted designators — LLC, L.L.C., Limited Liability Company and Limited Company. The checker searches the name with and without the suffix, because the suffix alone never makes a name distinguishable.
- Can I reserve a business name in Montana before I file?
- Yes. The Montana Secretary of State charges $10 to reserve a name for 120 days. A reserved name shows as taken to everyone else's search.
- How much does it cost to register a business name in Montana?
- The name itself is free to search. Filing the entity is what costs money: $35 for an LLC and $70 for a corporation, then annual report, $20, due april 15.
- Are there words I can't use in a Montana business name?
- Words that imply a regulated business need consent first. In Montana that includes Bank, Trust, Insurance, Engineer and Cooperative. Names that suggest a government agency are refused outright.
- How many new businesses start in Montana each year?
- The Census Bureau counted 32,518 business applications in the twelve months to August 2026, +15.1% on the year before. Not every application becomes a registered entity, but each one is a name someone intends to use.
