Does running a corporation in Montana involve more paperwork than running other types of businesses?

Both give liability protection. An LLC defaults to pass-through tax with fewer formalities. A corporation can issue stock and elect C-Corp or S-Corp tax treatment.

Can a non-US resident form a corporation in Montana?

Yes. Montana has no US residency requirement for shareholders or directors. You need a US agent (included) and an EIN from the IRS. Non-US owners generally cannot elect S-Corp, so the default is C-Corp tax.

Can I convert a Montana LLC into a corporation later?

Yes. Montana allows statutory conversion or a Delaware flip before a priced round. You file conversion papers and issue stock to former members.

What's the difference between a C-Corp and an S-Corp in Montana?

They are the same Montana corporation filing with the Montana Secretary of State. C-Corp is the default tax treatment. An S-Corp elects pass-through tax via Form 2553 but caps at 100 US shareholders and one stock class.

What is a Montana corporation?

A Montana corporation is a for-profit company filed with the Montana Secretary of State. The same entity can be taxed as a C-Corp (default — Form 1120, 21% federal corporate tax) or an S-Corp (Form 2553 pass-through). It is built for stock issuance, employee equity, and fundraising. For a full LLC vs corporation comparison, see our LLC vs corporation guide.

Low formation fee and no sales tax. Incorporate in MT when you operate primarily here and want a domestic corporation without a Delaware flip. Non-US founders can own 100%.

Why incorporate in Montana?

VC-ready structure — preferred stock, board governance, ISO options.
One domestic filing — $35 with the Montana Secretary of State; simpler than DE + foreign qualification for local operators.
Limited liability — shareholders are generally not personally liable for corporate debts.

Montana corporation pros and cons

Drawbacks to weigh before you incorporate:

C-Corp default means double taxation — 21% federal corporate tax, then tax again on dividends. An S-Corp election avoids that if you qualify.
More formalities — annual board and shareholder meetings, minutes, bylaws, and stock ledger maintenance.
Montana corporate tax: Corporate income tax (6.75%).
US VCs often prefer Delaware C-Corp over a Montana domestic corporation for priced rounds.

Types of corporations in Montana

C-Corporation — default tax treatment of the same corporation; unlimited shareholders and multiple stock classes.
S-Corporation — same formation filing, but elect pass-through tax via IRS Form 2553 (100-shareholder cap, one stock class).
Professional corporation (PC) — may be required for licensed professions; check Montana Secretary of State rules.
Nonprofit corporation — separate filing path if you seek 501(c)(3) status (not covered here).

Is a Montana corporation right for you?

Compare alternatives before filing:

LLC in Montana — simpler pass-through tax for owner-operated businesses.
S-Corp vs LLC — payroll tax savings with added compliance.
LLC vs corporation — full comparison of structures.
Best state to form a business — if you're weighing Montana vs Delaware.

Corporate governance in Montana

A Montana corporation is more formal than an LLC. After the Montana Secretary of State approves your filing:

Adopt corporate bylaws.
Appoint a board of directors.
Elect officers (President, Secretary, Treasurer — titles can vary).
Issue stock to founders at the organizational meeting.

What does a corporate board of directors do?

Oversees major decisions: budgets, stock issuances, CEO hire, financings.
Early-stage founders often sit on the board themselves.
Document decisions in written consents or meeting minutes.
Skipping minutes is the fastest way to lose corporate veil protection.

What kind of stock can I issue?

Authorize common stock for founders in your Articles of Incorporation.
Reserve preferred stock for future investors when needed.
List authorized share counts and par value on the formation document.
ClearFormation includes bylaws and stock certificates for founder issuance.

Officers and day-to-day operations

Officers run daily operations; the board sets strategy.
A solo founder can be the sole director and hold all officer roles.
Update cap table, bylaws, and board composition as you add co-founders or investors.

Foreign entities doing business in Montana

Out-of-state corps with staff, offices, or major sales in Montana may need to register as a foreign corporation with the Montana Secretary of State.
That filing needs a MT registered agent with a physical in-state address — included with ClearFormation.
If you incorporate in Montana but operate elsewhere, you may need to foreign-qualify in those states instead.
See our foreign qualification guide or get a MT registered agent.

How is a Montana corporation taxed?

By default a Montana corporation is a C-Corp and pays tax at these levels:

Files IRS Form 1120 and pays 21% federal corporate income tax on profits.
Dividends to shareholders are taxed again on personal returns — the classic double tax.
State level: Corporate income tax (6.75%)
File the Annual Report ($20) with the Montana Secretary of State.

Eligible US owners can elect S-Corp treatment (Form 2553) on the same corporation if they meet IRS rules. See S-Corp vs LLC. Operating outside Montana? You may need to foreign-qualify elsewhere.

Quarterly estimated taxes and payroll

Profitable C-Corps often pay quarterly estimated federal tax (Form 1120-W).
With employees in Montana, withhold payroll taxes and file state unemployment returns.
Budget for CPA support — corporate compliance is heavier than a pass-through LLC.

Foreign-owned corporations

25%+ foreign ownership may require IRS Form 5472 with the corporate return.
Non-US founders should plan for this from incorporation day.

How to dissolve a Montana corporation

Get board and shareholder approval to dissolve.
File Articles of Dissolution with the Montana Secretary of State.
Pay outstanding state taxes and cancel foreign registrations.
File a final IRS Form 1120. Skipping formal dissolution can trigger ongoing report fees.

Common Montana corporation mistakes

Missing the 83(b) election window. Founders with vesting stock must file within 30 days of issuance — there is no extension.
Skipping board meetings and minutes. Corporate formalities preserve the liability shield; skipping them is the #1 veil-piercing risk.
Commingling personal and corporate funds. Use a dedicated corporate bank account from day one.
Missing the annual report. Can cost you good standing or trigger administrative dissolution.

Corporation vs LLC in Montana: which should you form?

Both entities give you the same liability shield. The main differences are tax, ownership, and fundraising options. A corporation can be taxed as a C-Corp (default) or an S-Corp (Form 2553).

Form an LLC in Montana if

You want pass-through tax with less paperwork.
You do not plan to raise US venture capital.
You run a consulting firm, agency, store, or freelance business.
