Montana Annual Report Deadlines for LLCs in 2026

Montana is one of the easier annual-report states to understand in 2026, but only if you know one unusual detail:

• the filing is still due by April 15;
• but the annual-report fee is waived through April 15, 2026.

If you miss that date, Montana’s official filing-fee schedule says the annual-report fee becomes:

• $35 after April 15

So the real Montana rule this year is simple:

• file on time and pay no annual-report fee;
• file late and create a fee problem immediately.

Do Montana LLCs have to file an annual report?

Yes.

Montana’s Secretary of State has repeatedly reminded businesses that all LLCs and corporations must file annual reports to keep their registration up to date and confirm they remain active businesses.

The report is a renewal of your registration information, not a tax return.

When is the Montana LLC annual report due?

Montana’s Secretary of State says the annual report is due by:

• April 15, 2026

The filing portal and public reminders both point businesses to the same timing structure: complete the report during the January 1 to April 15 filing period to stay current without a late fee issue.

What is the Montana LLC annual-report fee in 2026?

Montana’s official business-fee page says:

• Annual Report Prior to April 15th: WAIVED
• Annual Report After April 15th: $35

The Secretary of State also publicly announced that the 2026 annual-report filing fee is waived again this year for Montana businesses that file on time.

That makes Montana different from many other states where the fee stays fixed regardless of timing.

What does the Montana annual report update?

Montana’s help materials describe the annual report as a renewal of registration information where the business can update:

• the business mailing address;
• the registered agent;
• principals of record; and
• other current business information.

That means the annual report is also a natural checkpoint for registered-agent accuracy.

Why the registered agent matters in Montana

If the registered-agent information is wrong, the annual report is often the moment owners finally notice the record drift.

That matters because the registered agent is still the point of contact for:

• legal documents;
• official notices; and
• business-record continuity.

If the Montana registered-agent record is stale, filing the annual report without fixing it just extends the weakness in the public record.

What happens if you file late?

Montana’s fee schedule says the filing fee jumps to $35 after April 15.

That is the immediate consequence. The broader risk is letting the business fall out of good standing and creating reinstatement or delinquency cleanup later.

The state’s renewal guidance is clear that businesses should submit the annual report before the deadline to maintain good standing.

Best way to handle the Montana filing in 2026

The cleanest process is:

1. log in to the official Montana business portal before April 15;
2. review the business mailing address and principal information;
3. confirm the registered agent is still correct;
4. file while the fee is still waived;
5. save proof of filing.
