If you’d rather not track this yourself
Bizee’s registered-agent and compliance service includes a due-date reminder and a filing option for Montana’s report. State filing fees are separate.
Bizee’s BBB rating, verified directly against BBB’s own listing on September 2, 2026: a C, not accredited. BBB’s own finding: the business “has failed to resolve underlying cause(s) of a pattern of complaints”, with 83 complaints filed. Most complaints we found described difficulty canceling recurring services and strict refund policies, worth knowing before you hand over a card for the year-two renewal. Check BBB’s current listing yourself before you buy; a rating we didn’t just verify is worse than none.

Whether Montana requires one, and how often
Montana requires LLCs to file an annual report every year. $0 if filed on or before April 15 (fee shown as WAIVED); $35 if filed after April 15.
When it’s due
The annual report must be delivered to the Secretary of State between January 1 and April 15 of the year following the calendar year the LLC was organized (and each year thereafter). (Mont. Code Ann. § 35-8-208)
What it costs
$0 if filed on or before April 15 (fee shown as WAIVED); $35 if filed after April 15 (source, read 2026-08-06).
What happens if you miss it
A $35 late fee applies once the annual report is filed after April 15 (the fee is shown as WAIVED entirely if filed on or before April 15). (Montana Secretary of State Business Fee Schedule)
What eventually happens if it stays unfiled: The Secretary of State may administratively (involuntarily) dissolve a domestic LLC that has failed for 140 days to file its annual report within the time required by law. (Mont. Code Ann. § 35-8-209) “has failed for 140 days to file its annual report within the time required by law”
Where to file
File at https://biz.sosmt.gov. Montana’s online business-filing portal (login required), the only accepted channel for annual reports; paper/mail filings are not accepted.
What this page does not answer
State income tax, franchise tax and federal (IRS) filing obligations are separate from this report and follow their own deadlines and rules. This page does not source those. We have the state periodic-report answer at primary and nothing else.
The annual/biennial report fee above is a recurring cost of keeping the LLC active, separate from what it cost to form. See what an LLC costs in Montana for the full cost picture.
