Start your LLCOfficial Montana Secretary of State business search database. Access the MT SOS business entity database to verify corporations, LLCs, partnerships, and other business registrations in Montana. Free government database with real-time information.
The Montana Secretary of State business search is the official government database that contains information about all business entities registered in Montana. This includes corporations, limited liability companies (LLCs), partnerships, and other business structures operating in MT.
When you search "secretary of state mt business search," you're looking for this official database to verify business registrations, check entity status, and conduct due diligence on Montana businesses.
Montana hosts business entity search and UCC lien search on biz.sosmt.gov under different paths. Use the business search for corporations, LLCs, and assumed business names, and use the UCC search for financing statement index results. Both sit on the same portal, but they are separate screens.
Montana business entities & Secretary of State workflows
Search by the name, number, or filters the Secretary of State exposes on the official business search form. Open the record for status, registered agent, and charter details. Read disclaimers on the site before you rely on results for legal or lending decisions.
Formations, annual reports, and amendments are filed through Secretary of State online services linked from biz.sosmt.gov or sosmt.gov. Sign in when the workflow requires an account and use published fees before you pay.
Financing statements & lien search
Use the UCC search path for debtor and file number style searches the index supports. Match legal names to how parties filed. Confirm on the live site whether you need a certified search or copy and follow the division fee process.

Form a business
Entity search on this page helps you verify names and good standing. When you are ready to form a new LLC, corporation, or nonprofit, use the same next steps we link from Business Lookup: confirm the name on the official register, choose a structure with your CPA or attorney if needed, then file through the state agency (and plan for publication, registered agent, and any industry licenses that apply).
These amounts can change when agencies update their fee schedules. Double-check the current fee list, forms, and deadlines on the official Montana business filing site yourself before you pay or submit anything.
