Michigan LLC Operating Agreement: Free Guide (2026)
Michigan doesn't require an operating agreement — but the Michigan LLC Act's default rules will run your company if you don't write your own. Here's what to include, why your bank asks for it anyway, and a builder that generates your custom clause checklist.
A Michigan LLC operating agreement is not legally required and is never filed with LARA — but every LLC should have one. It's the internal contract setting ownership percentages, profit splits, voting rules, and exit terms. Without it, the Michigan Limited Liability Company Act's default rules govern, which may not match your actual deal. Banks routinely require a signed agreement to open a business account, and for single-member LLCs it's core evidence of entity separateness. Cost: $0 with a template.

Why You Need One (Even Though Michigan Doesn't Ask)
The operating agreement is the contract between your LLC's members — and between you and your future self. The Michigan Limited Liability Company Act grants wide freedom of contract, which cuts both ways: write your rules and they govern; write nothing and the statutory defaults fill every gap on management, voting, and distributions, whether they match your intentions or not.
- Banks require it: expect to hand over a signed agreement, your stamped Articles, and your EIN letter to open the account.
- It hardens your liability shield: courts weighing veil-piercing claims look for evidence the LLC is a real, separate entity — a signed agreement is Exhibit A.
- It settles the hard questions early: profit splits, buyouts, a member's death or exit — answered while everyone still agrees.
- It controls the Flow-Through Entity Tax decision: if you later elect Michigan's FTE tax, your agreement should address how entity-level tax and distributions interact.
The default-rule trap: if your real deal — who invested what, who decides, who gets which share — differs from the statute's defaults and you never wrote it down, the statute wins. That's how handshake partnerships end up in Michigan courts arguing over what everyone "understood."

Single-Member LLCs: Yes, Still
Your bank will likely ask for it, and — more important — a single-member LLC's liability shield is the thinnest, so a signed agreement documenting separateness is your best evidence if anyone attacks it. It's also where a solo founder names a successor. Thirty minutes, the same afternoon your Articles clear.
Keeping It Current
Revisit the agreement when ownership changes, a member's role shifts, or you elect S-Corp taxation or Michigan's Flow-Through Entity Tax. Amendments follow whatever procedure the agreement sets — which is why the amendment clause matters on day one.
Ahmad Adil's Take: the operating agreement is the cheapest insurance in business, and Michigan's low fees make skipping it especially tempting — you've spent $50 and you feel done. Resist that. Every partnership blowup I've watched traces back to a question the founders never answered on paper: who decides, who gets what, who buys whom out and at what price. Michigan hands you total freedom to write those answers however you like; the mistake is not using it. Multi-member LLCs, do this before the money starts moving. Single-member owners, do it the same afternoon your Articles clear and file it with your EIN letter — that's your bank-account packet ready to go.
