Montana Business Name Search: How to Check and Reserve a Name

Before you file articles of organization or incorporation in Montana, you need to make sure your business name is available. A Montana business name search takes 10 minutes and costs nothing. A reservation costs $10 and locks in your name for 120 days. This article walks you through both.

Why a Montana Business Name Search Matters

Montana's Secretary of State maintains a registry of every LLC, corporation, nonprofit, and limited partnership filed in the state. If someone else has already claimed your name, you cannot use it. A name that is "too similar" to an existing business name also gets rejected. An unregistered or unreviewed name choice means you could file articles, pay the filing fee, and have the Secretary of State reject them all because the name was taken. A 5-minute search upfront saves that headache.

A name reservation is optional, but it gives you legal rights. Once you reserve a name, no one else can file a business under that name for 120 days, even if they search and find it available. After 120 days, your reservation expires. If you have not filed your articles by then, you need to reserve again or someone else can claim the name.

Montana Business Name Rules You Must Follow

If You Are Filing an LLC

Your business name must include one of these words or abbreviations at the end:

  • "Limited Liability Company" or "LLC"
  • "Limited Company" or "LC"
  • "l.l.c." or "l.c." (with periods)
  • "llc" or "lc" (no periods)
  • "Ltd." for "limited" and "Co." for "company" (e.g., "Your Name Ltd. Co.")

Examples of valid LLC names in Montana:

  • "Smith Contracting LLC"
  • "Blue Ridge Consulting Limited Liability Company"
  • "Evergreen Design l.l.c."

Your name must also be distinguishable from every other Montana or registered foreign corporation, nonprofit, limited partnership, and LLC name already on file. This means you cannot use a name that is the same or so similar a person might confuse the two. Adding a suffix like "of Montana," "Group," or "Inc." does not always make a name distinguishable if the core name is taken. The Secretary of State reviews this during the search.

If You Are Filing a Corporation

A corporation name must include "Corporation," "Corp.," "Incorporated," "Inc.," "Company," or "Co." at the end. The same "distinguishable" rule applies.

If You Are Filing a DBA (Assumed Business Name)

If you are operating a sole proprietorship or partnership under a name other than your legal name, you file an Assumed Business Name (ABN) with the Montana Secretary of State. The name must be distinguishable from existing ABNs, LLCs, corporations, and nonprofits on file. An ABN registration costs $20, runs for 5 years, and must be renewed 90 days before it expires or it is cancelled. You do NOT need to reserve an ABN name separately; you register it directly.

Step 1: Search for Your Montana Business Name (Free)

This search takes about 5 minutes and tells you whether your name is available.

  1. Go to the Montana Secretary of State business search tool. Visit https://biz.sosmt.gov/search/business. This is the official, free search portal operated by the Montana Secretary of State.
  2. Enter your proposed business name. Type the name exactly as you plan to use it in your filing. Do not include LLC, Inc., or other suffixes in this search; the search engine is smart enough to look for the core name across different business types and endings.
  3. Click "Search." The tool will return results in 1 to 3 seconds.
  4. Review the results. If your name appears in the list with a status of "Active" or "Current," it is taken and you cannot use it. If the results show "Withdrawn," "Dissolved," or "Inactive," the name may be available, but do not assume. Inactive names can sometimes be reactivated, and the Secretary of State may still reject you if the inactive name is too similar. If your name does not appear in the list at all, it is likely available, but the Secretary of State does the final review when you file.
  5. If available, conduct a second search with slight variations. Search for your name with common suffixes you plan to add ("LLC," "Inc.," "Company"). This helps you spot similar names that might cause a rejection later. For example, if you plan to file as "Smith Construction LLC," also search for "Smith Construction," "Smith Construction Inc.," and "Smith Builders" to see what is already out there.
  6. Document your search results. Take a screenshot or note the date and exact name you searched. This record proves you did your homework if there is ever a dispute later.

What the Search Results Mean

The search tool shows the entity name, entity type (LLC, corporation, etc.), registration status, and the Secretary of State file number. If a name shows as "Active," it belongs to someone else. If it shows as "Inactive" or "Dissolved," the business is no longer operating, but the Secretary of State might still flag your name as too similar. "Withdrawn" means the filing was rejected or the applicant cancelled it before approval. When in doubt about whether a name is truly available, a name reservation (described below) gives you the legal clarity you need.

Step 2: Reserve Your Montana Business Name (Optional, $10)

A name reservation is not required to file your articles of organization or incorporation. However, if you are still working on your business plan, securing funding, or waiting to file your official paperwork, a reservation prevents anyone else from claiming your name while you get ready. A reservation lasts exactly 120 days and cannot be renewed. If you want to keep the name reserved after 120 days, you must file your articles before the deadline expires.

  1. Go to the Montana Secretary of State online filing portal. Visit https://biz.sosmt.gov. This is the official portal for all Montana business filings.
  2. Click "File a New Document." The portal will prompt you to create an account or log in. If this is your first time, you will need to register with your email address and create a password.
  3. Select "Application for Reservation of Name." This is the document type you need to file a name reservation.
  4. Enter the name you want to reserve. Type the exact name, including the LLC or Corp. designation if applicable.
  5. Choose the entity type: LLC, Corporation, Nonprofit Corporation, or Limited Partnership. This tells the Secretary of State which registry to check against.
  6. Provide the name and address of the reserving applicant. This is you (or your company if you are filing on behalf of the business). This information is public record.
  7. Pay the $10 reservation fee. You can pay by credit card or electronic check through the online portal.
  8. Review and submit. Double-check all information for spelling and accuracy. Submit the application. You will receive a confirmation email with your filing number within a few minutes.
  9. Keep your confirmation email and filing number. You will need this number if you want to verify the reservation status or if you encounter any issues.
  10. File your articles of organization or incorporation before the 120-day deadline. If you file your articles before the reservation expires, the name is legally protected. If the 120 days pass without a filing, anyone else can reserve or use the name.

Processing Time for Reservations

The Montana Secretary of State does not publish a standard processing time for name reservations. Most reservations are approved within 1 to 3 business days. If you need faster approval, you can add a priority handling fee of $20 for 24-hour processing or $100 for 1-hour processing (on top of the $10 reservation fee). For most startups, the standard processing time is fine.

Tips and Common Mistakes to Avoid

Common Mistakes

  • Not searching for variations of your name. The search tool is case-insensitive and ignores punctuation, but the Secretary of State's human reviewers will catch a name that is too similar to an existing one. Search for your name with and without the LLC or Inc. designation, and also search for close variations (e.g., "Smith Construction" and "Smith Builders") to get a full picture of what is already taken.
  • Assuming inactive or dissolved names are free. A dissolved LLC can sometimes be reactivated, and the Secretary of State considers the history. If a similar inactive name exists, your application might still be rejected. When in doubt, contact the Secretary of State's business registration team for guidance.
  • Filing articles before the name reservation is approved. The reservation must be active before you file your articles. If you file before the reservation is approved, your articles might be rejected for a name conflict.
  • Letting a 120-day reservation expire without filing. Once the 120 days are up, the name becomes available to anyone. You cannot renew a reservation; you have to file your articles before the deadline or start over.
  • Not checking for registered trademarks or domain names. The Secretary of State's search only checks Montana business entity names. Before you commit to a business name, search the U.S. Patent and Trademark Office (uspto.gov) to make sure a similar name is not already trademarked. Also check domain name availability (godaddy.com, namecheap.com) to see if your preferred domain is for sale. A Montana business name can be available but the domain name or trademark taken by someone else.

Pro Tips

  • Use the online portal, not phone or mail. The Montana Secretary of State online filing portal at https://biz.sosmt.gov is faster and more reliable than calling or mailing in a paper application. You get a confirmation email immediately, and you can track your filing status anytime.
  • Do a name search before paying for a logo, website, or business cards. Once you have spent money on branding, it is hard to change the name. A 5-minute free search at the start saves that cost later.
  • Consider a slightly broader name if your first choice is borderline. If the Secretary of State flags your name as too similar to an existing entity, having a backup name ready speeds up the approval process. You can reserve multiple names (at $10 each) if you want to explore options.
  • Save your Secretary of State confirmation email for your records. This email is proof that you filed with the state and when. Keep it for your business files and taxes.

What to Expect: Timeline and Results

Name Search Results: Instant. You get your search results within 1 to 3 seconds of clicking "Search."

Reservation Approval: 1 to 3 business days for standard processing. If you pay for expedited handling ($20 for 24 hours or $100 for 1 hour), you will have approval faster.

After Reservation Approval: Your name is legally reserved for 120 days, starting from the approval date. You can now file your articles of organization or incorporation anytime within that 120-day window. The filing takes another 1 to 3 business days (or faster with expedited processing).

After Articles Are Filed and Approved: Your business is officially registered with the Montana Secretary of State. You will receive a confirmation email and a filed copy of your articles. At this point, your business name is registered and no one else can use it (unless you dissolve or voluntarily abandon it).

What Comes Next After Your Name is Reserved or Filed

Once your business name is secured, the next steps depend on your business structure and type:

  • LLC owners: Obtain an Employer Identification Number (EIN) from the IRS (even if you are a sole-member LLC). Set up a business bank account. Apply for any local business licenses or permits required by your city or county.
  • Corporation owners: Obtain an EIN. Issue stock to shareholders. Set up a corporate bank account. File annual reports with the Montana Secretary of State (due April 15 each year).
  • DBA filers: File your ABN with the Secretary of State (if you have not already). Obtain an EIN if the business has employees. Apply for local business licenses. Some counties also require a separate ABN filing at the county level; check with your county clerk.

Do not skip the local licensing step. Montana has no statewide general business license, but your city and county likely require one. Check your city or county website for details.
