Stay current before the registry makes the decision for you.

Annual reporting is a recurring statutory obligation. The right deadline, fee, and cure strategy depend on entity type, formation date, fiscal year, and whether the record is already delinquent.

How to read the obligation

Separate the registry report from the tax account.

An annual report, annual registration, or periodic statement generally keeps the public entity record current. It may update an address, agent, officer, manager, principal office, or other statutory information. It does not necessarily replace a franchise-tax return, income-tax filing, sales-tax return, business license renewal, or beneficial-ownership filing.

Before putting a deadline on a calendar, identify the entity’s domestic or foreign status, the formation or qualification date, the reporting period, the current registered agent, and the agency that receives the payment. If the entity changed states, converted, merged, or was reinstated, the anniversary logic may not be what a new operator expects.

LLCRecurring obligation

Limited liability company

Montana LLC annual reports are due April 15. The state has waived the ordinary annual-report filing fee for the current 2026 cycle according to the public filing notices; an annual report filed after April 15 is listed with a $35.00 late fee. The report updates agent, office, and management information.

Practical checkpoint

Confirm the due date in the entity’s live record, review the agent and principal address before filing, and retain the accepted report and payment confirmation.

CORPRecurring obligation

Corporation

Montana corporations file annual reports by April 15 under the Secretary's annual cycle. The current fee schedule should be checked for the 2026 waiver or charge and for the $35.00 late filing amount shown for late annual reports. Annual reporting is separate from Montana tax returns.

Information discipline

Corporations may have to report officers, directors, issued shares, principal offices, or other public information. Review the filing carefully before submission.

Tax and franchise context

A report fee is not the whole annual cost.

No separate Montana Secretary-of-State corporate franchise tax applies as a registry charge. Montana corporate income and business tax obligations are administered by the Department of Revenue and depend on income, apportionment, and classification. SOS annual-report and late fees are separate.

Emergency cure desk

If the deadline has passed, treat the record as an active legal issue.

Late-filing consequences

Montana's fee rules list a $35.00 annual-report late fee after April 15. Other delinquent charges can include reinstatement and each missing annual report. Tax penalties and interest are separately assessed by the Department of Revenue.

Montana can involuntarily dissolve or revoke an entity for missing annual reports, fees, or registered-agent requirements. The reviewed public pages do not state one universal day-by-day warning sequence; notices and Montana Code control. Delinquency risks loss of good standing, name rights, service, and limited-liability administration.

Reinstatement playbook

Search the Montana record, file every missing annual report, correct the agent and office, submit the application for reinstatement, and pay the reinstatement charge plus $35.00 for each delinquent annual report where required. Confirm active status and separately resolve Montana tax filings and balances.

Financial exposure: Montana's LLC rules list reinstatement plus $35.00 for each year of delinquent annual reports; corporation amounts are entity-specific. The current portal calculates the complete fee. Montana Department of Revenue back taxes, interest, and penalties are separate and not included in SOS reinstatement.

A disciplined annual-report workflow

1. Verify status before filing

Search the entity by legal name or ID and confirm whether it is active, delinquent, revoked, expired, or administratively dissolved. A report may not be accepted online when the entity is already out of good standing.

2. Reconcile public information

Compare the state record with the operating agreement, charter, board or manager records, registered-agent engagement, tax account, and principal-office information. A report can be a compliance control, not just a payment screen.

3. Cure every related default

File missing reports, pay the correct base fees and penalties, replace a failed agent, obtain tax clearances when required, and submit the reinstatement or requalification document. Partial payment may leave the entity in the same status.

4. Preserve evidence

Save the accepted filing, receipt, certificate, and updated public search result. Lenders, buyers, contracting partners, and foreign registrars often need proof that the cure actually posted.

Do not confuse administrative status with dissolution

An administrative termination or revocation is a state action against the registration. It is not always the same as a voluntary dissolution, a tax closure, or a final winding-up process. Review the jurisdiction’s cure rules and the entity’s obligations to creditors, owners, employees, and taxing authorities before treating the matter as closed.
