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.

The fee estimate applies to the selected report year. On-time 2026/2027 reports cost $0; filing after April 15 currently costs $35 total. For other years, check the then-current SOS schedule rather than assuming the temporary waiver continues. The next upcoming deadline does not identify or clear past-due reports.
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.
- The current post-April-15 filing amount is $35 total. The on-time waiver does not apply after April 15.
If you miss April 15: the current annual-report filing amount is $35 total. Continued non-filing can lead to administrative dissolution or revocation; check the entity’s status and any separate reinstatement requirements with the SOS. Current SOS annual-report instructions.
