Montana Corporation Annual Requirements and Ongoing Compliance

Montana's signature annual obligation for corporations is the annual report, filed with the Secretary of State through the online portal. The one thing to burn into memory: it's due April 15 every year. Montana uses a single fixed date for all business entities rather than tying the deadline to your formation anniversary, which makes it easy to remember but also easy to overlook if you're not watching the calendar.

What the report does

The annual report isn't a financial disclosure. You're not reporting revenue, profit, or expenses. It confirms and updates the state's record: your registered agent and their Montana address, your principal office, and your officer and director information. You file it online through the portal after logging in with ePass Montana, and you pay the state fee at the same time.

Why the fixed date matters

Because the deadline is the same for every corporation, there's no personalized reminder built into your formation date to jog your memory. New owners who assume the report is due "a year after I formed" get caught out. Set an annual reminder for early April so the filing is done well before the 15th.

A corporation earns its liability protection by behaving like a corporation. The Montana Business Corporation Act assumes certain internal rhythms, and skipping them is one of the ways owners quietly undermine the very shield they incorporated to get.

Annual meetings

Corporations are expected to hold an annual shareholders' meeting to elect directors and an annual board of directors' meeting to handle governance. In a one-person corporation these can be brief and largely a formality, but they should still happen and be documented — the fact that they happened is what matters if the corporation is ever challenged.

Minutes and records

Record minutes of every meeting and keep them in your corporate records book, alongside your bylaws, stock ledger, and major resolutions. When someone challenges the corporation in court and tries to reach the owners personally, these records are the evidence that the corporation is a real, separate entity — not a personal alter ego. Thin or missing records are exactly what plaintiffs point to when arguing to pierce the veil.

Stock records

Maintain an accurate record of who owns shares, how many, of what class, and when they were issued or transferred. As the corporation issues stock to new investors or employees, keep the ledger current. Clean stock records prevent ownership disputes and are essential if you ever raise money or sell the company.

Your corporation's public record with the Secretary of State has to stay accurate throughout its life, and the annual report is the moment you confirm it — but changes between reports need handling too.

Keep the registered agent current

You must maintain a valid registered agent with a physical Montana address at all times. If your agent moves, resigns, or you switch to a service, file a change with the Secretary of State through the portal promptly — don't wait for the next annual report. A stale agent leaves the corporation reachable only on paper and can lead to missed lawsuits and loss of good standing.

Report structural changes

Significant changes to the corporation — a new corporate name, an amendment to the Articles of Incorporation, or a change in authorized shares — are filed with the Secretary of State through the appropriate amendment. Internal changes like electing new officers are recorded in your minutes rather than filed, but anything that alters the Articles goes on the public record and shouldn't wait until April.

Beyond the annual report, your corporation carries tax obligations tied to how it's structured and what it does. These are separate from the Secretary of State filing.

Federal returns

A C corporation files its own federal income tax return, Form 1120. An S corporation files Form 1120-S and passes income through to shareholders, who report it on their personal returns. If you elected S status with Form 2553, keep the election paperwork with your records and file on the S corporation schedule.

Montana state taxes

Montana has no general sales tax, which spares corporations the sales tax collection and remittance that most states require — one fewer recurring filing. Montana does have a state income tax, so a C corporation owes Montana corporate income tax, and S corporation income flows through to shareholders' Montana individual returns. If you have employees, you'll handle Montana withholding and unemployment obligations. All of this runs through the Montana Department of Revenue, a different agency than the Secretary of State that maintains your entity record.

Local licensing

Depending on your activity and location, Montana cities, counties, and certain state boards may require licenses or permits, renewed on their own schedules. These are separate from your corporate filing and easy to overlook if you assume state formation covered everything.

The consequences of missing Montana's requirements build gradually, which is what makes them dangerous — nothing dramatic happens on day one, so it's easy to let things slide until the cost is real.

The slide toward dissolution

Miss the April 15 annual report and a late penalty attaches. Let it continue, or let the registered agent lapse, and the corporation falls out of good standing. Continued non-compliance can lead to involuntary dissolution, at which point the corporation loses the right to sue, to sign enforceable contracts in its name, and the liability shield itself can be called into question for the period it was dissolved.

Reinstatement is the expensive path

Montana generally allows a dissolved corporation to reinstate, but doing so means clearing the back fees, penalties, and a reinstatement charge. It's more work and more money than simply staying current. The takeaway is the same every year: file the annual report by April 15, hold and document the meetings, keep the agent valid, and stay current on taxes.

Build a simple annual routine

Set a reminder for early April for the annual report, another for your annual shareholder and director meetings, and a check each year that your registered agent is still valid and your records are current. A corporation kept in good standing is boring in the best way — no surprises, no scrambles, no reinstatement.
