Annual Requirements for a Montana Nonprofit Corporation

The centerpiece of state-level compliance is the annual report filed with the Montana Secretary of State. Every Montana nonprofit corporation has to file it to remain in good standing.

The essentials

• Deadline: April 15 every year. The date is fixed and doesn't move with your fiscal year, so it's easy to calendar.
• Filed online through the biz.sosmt.gov portal using your ePass Montana login.
• Confirms your information — the registered agent, the registered office address, and the corporation's principal details.

What it is and isn't

The annual report is not a financial disclosure. You're not reporting revenue, expenses, program budgets, or donor information to the state. It's an identity-and-contact confirmation that keeps the public record accurate. That's an important distinction, because founders sometimes conflate the state annual report with the far more detailed federal Form 990 — they are separate filings serving different purposes.

Any fee is shown on the receipt when you file, and Montana has periodically waived on-time filing fees. Either way, the filing itself is the obligation; get it in by April 15 and the corporation stays active.

Separate from the state, every tax-exempt organization has an annual filing obligation with the IRS. This is where a nonprofit's actual financial picture gets reported.

Which 990 you file

• Form 990-N (the "e-Postcard") for the smallest organizations under the IRS gross-receipts threshold — a brief electronic notice.
• Form 990-EZ for mid-sized organizations within the applicable thresholds.
• Form 990 (full) for larger organizations.

The version you file is determined by the organization's gross receipts and total assets, and those thresholds are set by the IRS. The return is generally due by the 15th day of the fifth month after your fiscal year ends — for a calendar-year organization, that's May 15.

Why it matters so much

Failing to file the required 990 for three consecutive years triggers automatic revocation of tax-exempt status. Getting reinstated after automatic revocation is a real ordeal — a new application, back filings, and a gap in exempt status that can jeopardize grants and donor confidence. Of all the annual obligations, the 990 is the one whose neglect carries the harshest consequence, so treat it as non-negotiable even in a quiet year.

Compliance isn't only about periodic filings — it's also about the continuous obligation to keep a valid registered agent on file at all times.

What "maintaining" means

• The agent must keep a physical Montana street address that's current in the state record.
• The agent must remain available during business hours to receive service of process.
• Any change — the agent moving, resigning, or being replaced — has to be filed promptly with the Secretary of State.

An outdated registered agent record is a quiet compliance failure. The annual report can be filed and the 990 current, but if your agent moved and the record still shows the old address, the corporation is technically non-compliant, and a lawsuit could be served at an address nobody monitors. A commercial agent keeps this obligation steady because its address doesn't change when your board does.

Beyond filings, staying a legitimate nonprofit means actually operating like one. These aren't filings you submit, but they're expectations that regulators, funders, and courts assume you're meeting.

Board activity and minutes

Hold board meetings as your bylaws require, and keep minutes recording who attended, what was decided, and how directors voted on significant matters. Minutes are the evidence that the board is genuinely governing. If a decision is ever challenged, or the IRS ever examines the organization, the minutes are what demonstrate proper process.

Keeping records current

Maintain a corporate records file: the accepted Articles of Incorporation, current bylaws and any amendments, the conflict-of-interest policy, the EIN letter, and the IRS determination letter. Update officer and director information as leadership changes. This file is what a bank, a grantmaker, or an auditor will ask to see, and a well-kept one signals a serious organization.

Consistency with the exempt purpose

To keep 501(c)(3) status, the organization has to keep operating consistently with its stated exempt purpose, avoid private benefit and inurement (no using the organization to enrich insiders), and steer clear of prohibited political activity. These aren't annual filings, but they're ongoing conditions of remaining exempt.

Put together, the recurring obligations form a manageable annual calendar. Building it into your routine is what keeps the organization out of trouble.

The recurring calendar

• April 15 — Montana annual report due to the Secretary of State.
• 15th day of the fifth month after fiscal year-end — IRS Form 990-series return due (May 15 for calendar-year organizations).
• Continuously — maintain a valid registered agent; update the record promptly on any change.
• Per your bylaws — hold board meetings and keep minutes.

If a deadline slips

Miss the Montana annual report and the corporation falls out of good standing; leave it unfiled long enough and the state can administratively dissolve it, after which reinstatement costs more time and money than timely filing would have. Miss the 990 for three straight years and the IRS automatically revokes exempt status. Let the registered agent lapse and you risk both non-compliance and being blindsided by a lawsuit. None of these outcomes is hard to avoid — they all come down to a short list of dates. If we serve as your registered agent, we track the April 15 deadline and remind you, so the state side of the calendar doesn't depend on any one volunteer remembering it.
