When is the Montana LLC annual report due?

4 min read·Published April 1, 2026·Updated July 1, 2026
Short answer

The Montana LLC annual report is due by April 15 each year. It keeps the LLC in good standing and is a short state filing, not a tax return. Miss it and the state can add a late fee and eventually dissolve the LLC.

If your vehicle is registered through a Montana LLC, the LLC has one recurring obligation: the annual report. It is due April 15 every year. Missing it puts the LLC, and therefore the vehicle's registration, at risk.

What the annual report is

The annual report is a short filing with the Montana Secretary of State confirming the LLC's basic details: name, registered agent, and address. It is not a tax return and does not report income. It exists to keep the state's record of your entity current.

The deadline and the cost

  • Due date: April 15 each year.
  • It is filed with the Secretary of State, separate from any tax.
  • A late filing triggers a state penalty.
  • Prolonged non-filing leads to involuntary dissolution of the LLC.
If the LLC is dissolved for a missed report, the vehicle's Montana registration is tied to an entity that no longer exists. Reinstatement is possible but slower and more expensive than filing on time.

How we handle it

Our $149 Registered Agent Renewal prepares and files the annual report for you and sends a reminder before April 15. If you manage the LLC yourself, calendar the date now; the filing takes minutes but the consequences of forgetting it compound.
