Montana LLC Operating Agreement — Step 4 of 8
Montana doesn't require you to file an operating agreement — but it's the internal document that spells out who owns what, how decisions get made, and what happens if a member leaves. Banks often ask for one, and it's a key piece of your liability protection. Here's what to include, with a clause builder to outline yours.
Montana does not require an LLC operating agreement, but it's strongly recommended. It's an internal document — you never file it with the Secretary of State — that spells out ownership, management, capital contributions, and how profits are split. Even single-member LLCs should have one, since it reinforces your liability protection and is often required to open a business bank account.

Why You Need One Anyway
Montana law doesn't force you to file an operating agreement — it's not part of the Articles of Organization and it never goes to the Secretary of State. But "not required" doesn't mean "not important." An operating agreement is what turns your LLC from a state filing into an actual, functioning business with clear rules:
- Reinforces liability protection — it documents that your LLC is a separate entity from you personally, which matters if anyone ever tries to "pierce the corporate veil."
- Banks often require it to open a business account — even for a single-member LLC.
- Settles disputes before they happen — ownership splits, decision-making, and exit terms are all defined up front instead of argued about later.
- Overrides Montana's default rules — without one, state default LLC law governs your business, which may not match what you actually want.
Operating Agreement Clause Builder
Toggle the clauses you want and the outline builds on the right. The first five are essentials almost every LLC needs; the rest are smart additions. Copy your outline to hand to a template or attorney:

Single-Member LLCs Need One Too
It's tempting to skip the operating agreement when you're the only owner — after all, who are you agreeing with? But a single-member operating agreement does something important: it documents that the LLC is genuinely separate from you personally. If anyone ever challenges your liability protection, that written separation is part of what protects your personal assets. It also helps when opening a bank account, and it lets you spell out what happens to the business if something happens to you.
Without one, Montana's default rules applyIf you don't have an operating agreement, Montana's LLC statute fills in the gaps for you — and its defaults may not match what you and your co-owners actually want (voting, profit splits, what happens if a member leaves). Writing your own agreement means you control those terms instead of the state's default assumptions.
