Look up a Montana company
Montana only allows its search on its own site, so this opens in a new tab. It finds the company, not usually its EIN.
What the Montana business search shows
The Montana Secretary of State keeps Montana’s record of companies formed or registered there. Use it to confirm a company’s exact legal name and whether it is active.
The Montana filing number
The Montana Secretary of State gives every company a filing number when it is formed. It identifies the company in state records, and it is not the company’s EIN.
Check if a Montana LLC is active
Search the company in the Montana business search and open its record. The status tells you whether the state counts the company as active. Words such as dissolved, revoked, forfeited, inactive or delinquent mean it is not in good standing, usually because an annual filing or fee was missed, and the company may need to be reinstated before it can do business there.
To prove a company is in good standing to a bank, a lender or another state, order a Certificate of Existence from the Montana Secretary of State. Our LLC status check reads the status from public data where a state publishes it.
Good to know in Montana
- Montana has no general sales tax, so most Montana LLCs never register for a seller's permit. To buy inventory tax-free from an out-of-state vendor, a Montana business can offer the Montana Business Registry Resale Certificate, which identifies it by its Secretary of State business registration number rather than a state sales tax number; the vendor may accept it but does not have to.
- Lodging is the main exception to Montana's lack of a sales tax. Hotels, campgrounds and vacation rentals collect the lodging facility sales and use tax, and each lodging accommodation must apply to the Department of Revenue for a seller's permit before doing business; short-term rental marketplaces collect the tax on bookings they facilitate.
- A Montana professional LLC files more than the Secretary of State's annual report: before April 15 each year it also files a statement of qualification, listing its members and managers, with each licensing authority that governs the professional services named in its articles of organization.
