Montana Corporation Costs — What to Budget for Incorporating

Incorporating in Montana starts with a state filing fee for the Articles of Incorporation, paid to the Secretary of State through the online portal. This is the charge that creates your corporation in the official record. The receipt card on this page reflects the current amount; state fees are stable but change occasionally, so it's always the figure to trust.

Online only — no channel choice to worry about

Some states charge different amounts for online versus paper filings. Montana sidesteps that entirely because it files online only. There's one filing fee, paid electronically through the portal, and no paper premium or discount to weigh. It also means no mailing costs and no waiting on postal processing on either end.

Where Montana lands on price

Compared with the pricier incorporation states, Montana's formation fee is on the lower, more affordable end. It's a genuine consideration for founders choosing where to incorporate, though for most businesses the right state to incorporate in is the state where you actually operate — the fee difference rarely outweighs the cost and hassle of foreign qualification if you form somewhere you don't do business.

The recurring state cost for a Montana corporation is the annual report, filed with the Secretary of State through the portal and due April 15 every year. Montana uses a single fixed date for all entities rather than your formation anniversary, which is easy to remember once you know it.

What it costs and what it does

The annual report carries a state fee shown on the receipt card. The filing itself is administrative, not a financial disclosure — it confirms your registered agent, principal office, and officer and director information so the state's record stays current. Budget for it as a small, predictable yearly line item.

The cost of filing late

Miss April 15 and Montana adds a late penalty on top of the base fee. Let the report go unfiled long enough and the corporation can lose good standing and eventually face involuntary dissolution — at which point the cost of getting back on track jumps well past the modest annual fee. Filing on time is by far the cheapest path.

Every Montana corporation needs a registered agent, and how you fill the role affects your budget.

Serving yourself

Acting as your own agent costs nothing directly, but the trade-offs carry their own price. Your name and address go on the public record, and you have to be personally available during business hours to accept legal process. For some owners the savings are worth it; for others the privacy and reliability of a service outweigh the fee.

A commercial service

A commercial registered agent charges an annual fee in exchange for providing the Montana address, staffing it, keeping it current with the state, and forwarding what arrives. Hire one on its own and that's a recurring annual cost to budget; form with Mainstay Filing and the agent is built into the one flat yearly price alongside the formation filing and the April 15 report, so it never surfaces as a separate charge.

Montana's tax picture is friendlier than most states in one respect and standard in another, and both affect your budgeting.

No general sales tax

Montana is one of the few states with no general statewide sales tax. For a corporation selling goods, that removes an entire category of collection, remittance, and filing that businesses in most other states have to manage. It's a real operational saving, not just a cost saving.

State income tax still applies

Montana does levy a state income tax, so a C corporation reports and pays Montana corporate income tax through the Department of Revenue, and S corporation shareholders report their pass-through share on their Montana individual returns. This isn't a fee you pay the Secretary of State — it's a tax tied to your profits — but it belongs in your budgeting. A CPA can estimate it based on your projected income.

Beyond the state fees and taxes, a few costs come with running a corporation properly. None are exotic, but budgeting for them prevents surprises.

The common line items

• EIN: Free directly from the IRS. Be wary of third-party sites that charge for what the IRS provides at no cost.
• Business licenses and permits: Montana licensing depends on your activity and locality — some professions and industries require state licensure, and cities and counties may have their own requirements. These run on their own cycles, separate from your corporate filing.
• Registered agent renewal: a standalone service renews annually; with Mainstay it's already inside the single yearly price.
• Foreign qualification (if applicable): A Montana corporation expanding into another state pays that state's qualification fee and needs a registered agent there; likewise, an out-of-state corporation qualifying in Montana pays the Certificate of Authority fee.
• Professional help: An attorney for shareholder agreements or complex stock structures, and a CPA for the S corporation election and tax planning, are optional but often worthwhile.

Reinstatement — the cost you want to avoid

The most avoidable expense is reinstatement after a lapse. If the corporation falls out of good standing for a missed annual report or an invalid registered agent, getting it back typically means paying the back fees, penalties, and a reinstatement charge — well above the cost of simply staying current. The cheapest year of compliance is always cheaper than the cheapest reinstatement.
