Montana annual reports, deadlines, and fees
Start with your entity type below. Montana reporting schedules can differ for LLCs and corporations; a report may be annual, biennial, or not required for a particular entity type.
Open Montana filing agency ↗Montana LLC reports
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.
Montana corporation reports
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.
Montana franchise and business taxes
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.
A registry report and a tax filing can have different deadlines and payment recipients. Check both before considering the year complete.
Late fees and missed-report penalties
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.
Administrative dissolution and notices
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.
Reinstate a Montana business
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.
Reinstatement costs and back taxes
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.
