Registered Agent in Montana: requirements, cost & best options

Montana offers less privacy than its reputation suggests. The registered-agent address is public, and — more importantly — MCA 35-8-208 requires the annual report to list the names and business mailing addresses of the LLC's members or managers, so ownership is on the public record every year regardless of who your agent is. A commercial agent keeps your street address off the record (their name alone goes on the filing, no address required, per the MORAA commercial-agent system), but it cannot make a Montana LLC anonymous. Filers who want ownership privacy usually look at Wyoming or New Mexico instead.

Out-of-state & non-resident founders: Members don't need any Montana connection, but a noncommercial agent must serve at an actual Montana street address — which a remote owner can't supply, so out-of-state founders use a commercial registered agent. Two non-resident realities: first, the annual report will still publish your name and mailing address as a member or manager. Second, if you're forming a Montana LLC to register a vehicle you'll garage in your home state, understand that Montana's no-sales-tax advantage doesn't neutralize your own state's use tax — enforcement (license-plate readers, data sharing, penalty statutes in states like Utah and Georgia) is aimed at exactly this arrangement.

Montana runs its business registry entirely online: formations, annual reports, and amendments all go through biz.sosmt.gov (an ePass Montana login), and the Secretary of State doesn't accept paper filings. Standard processing takes a few business days, and Montana sells real speed cheap — $20 for 24-hour processing, $100 for 1-hour — on top of the $35 Articles of Organization, the lowest formation fee of any state.

The annual report is where Montana is currently unbeatable. It's due January 1 – April 15 each year (first one the calendar year after you form), and the normal $20 fee has been waived for on-time filers every year since 2024 — Secretary Jacobsen renewed it for 2026 and 2027, a package the office says will save Montana businesses over $21 million. File after April 15 and the fee is $35; keep ignoring it and the SoS involuntarily dissolves the company on December 1, with reinstatement possible for up to five years (back reports plus a $35 reinstatement filing). One privacy note: under MCA 35-8-208, the report lists the names and business mailing addresses of your members or managers — Montana is not an anonymous-LLC state.

Agent rules follow the Model Registered Agents Act, which Montana adopted as MCA Title 35, chapter 7 — so the state formally splits agents into commercial (listed with the SoS under 35-7-106; you appoint them by name alone, which is how Northwest and its peers appear on your filing) and noncommercial (anyone else, listed with an actual Montana street address or rural route box number — a PO box alone fails 35-7-104). Appointing an agent is a statutory affirmation they've consented (35-7-105), and a change of agent is free, which almost no state matches.

Tax is Montana's headline: no state or local sales tax — one of five states — plus no franchise tax and no annual-report fee for now, so a compliant Montana LLC currently costs $35 total to create and maintain through 2027. C-corps pay a flat 6.75% income tax ($50 minimum); default LLCs pass through to the owners' 4.7%/5.65% individual brackets (top rate scheduled to fall to 5.4% in 2027). There is no publication requirement. And the vehicle-LLC industry that no-sales-tax spawned deserves its own honest paragraph — see the quirk above: Montana's end is legal, but your home state's use-tax enforcement is real and increasingly aggressive.
