Montana LLC Annual Report — Step 6 of 8
Every Montana LLC files an annual report by April 15 to stay in good standing. The fee is normally $20 — but the Secretary of State has waived it for on-time filers through 2027. Here's exactly when yours is due, and what a late filing costs.
Montana LLCs file an annual report every year by April 15 through the Business Filing Portal (biz.sosmt.gov). The standard fee is $20, but it's waived for on-time filers through 2027. Miss the deadline and you'll owe a $15 late fee; continued non-filing can lead to administrative dissolution.

What the Annual Report Is
The annual report is a short online filing that confirms your LLC's information is still accurate — your registered agent, principal office address, and member/manager details. It's a compliance update, not a tax return or financial filing. Montana requires it from every LLC, corporation, and foreign entity registered to do business in the state.

*Estimate only, assuming the current fee waiver (through 2027) is still in effect and you file on time. If the waiver has expired, add the standard $20 fee. The $15 late fee applies once a filing is late; continued non-filing can lead to administrative dissolution. Confirm exact amounts with the Secretary of State.
How & When to File
- File online at the Montana Business Filing Portal (biz.sosmt.gov) — paper filings aren't accepted.
- Mark April 15 on your calendar each year — the date never changes, so it's easy to automate a reminder.
- Confirm your details — registered agent, principal office address, and member/manager information — and update anything that's changed.
- Let your registered agent help — many agents send reminders, and some can file on your behalf.
The Fee Waiver — What It Does and Doesn't Cover
Montana's Secretary of State has waived the annual report fee for on-time filers for four consecutive years running: 2024, 2025, 2026, and 2027. That's real savings — but two things to keep in mind:
- The waiver covers the fee, not the requirement — you still must file every year, on time, even though it costs $0.
- Filing late still costs $15 — the waiver applies to on-time filings only.
What happens if you miss itMissing April 15 triggers a $15 late fee right away. If you keep not filing, the Secretary of State can place your LLC in administrative dissolution. Reinstating costs a $35 base fee plus $35 for each delinquent year — and if someone else registers your business name in the meantime, you may need to rename your LLC to come back.
