LLC Operating Agreement: What It Is, What to Include, and Why You Need One

Forming an LLC with your state is only half the job. The state gives you the entity — but it's the operating agreement that actually defines how the LLC works: who owns what, who decides what, and what happens when someone leaves, dies, or wants out.

And here's the part most people miss: even single-member LLCs need one. Without it, a court can treat your "LLC" as you personally — which is exactly the liability you formed the LLC to avoid.

What an LLC operating agreement actually is

It's the internal contract among the LLC's members (owners) that governs the company. It sits above your state's default LLC statute. Most states have a "default" LLC act that applies only when members haven't agreed otherwise — and those defaults are generic, one-size-fits-all rules written for a hypothetical average company, not yours.

If you never sign an operating agreement, you've effectively agreed to let the state legislature draft your company's rules. That's rarely what you want.

Why single-member LLCs still need one

A single-member LLC has no co-owners to disagree with — so why bother? Two reasons:

1. The corporate veil. The whole point of an LLC is separating your personal assets from business debts. Courts pierce that veil most easily when the LLC looks like a disguised alter ego of the owner — no separate governing document, no separate bank account, personal and business expenses mixed. An operating agreement is your exhibit A that the LLC is a real, separate entity.
2. What happens if you're incapacitated or die. Without an agreement naming a successor, your state's intestacy or guardianship laws — not your wishes — decide who controls the LLC and its assets.

The 8 clauses every operating agreement should have

1. Ownership percentages

How is the LLC split? List each member and their percentage. For multi-member LLCs this is obvious; for single-member it's 100%/you, stated explicitly.

2. Capital contributions

What did each member put in — cash, property, services, IP? This anchors profit splits and buyout math later.

3. Profit and loss distribution

Default statutes usually distribute proportionally to ownership. If you want something else (e.g., a member who contributed sweat equity gets a smaller share of profits than ownership), say it here.

4. Management structure

Member-managed (all owners run the business) vs. manager-managed (owners hire a manager). This matters for who can bind the LLC to contracts. Get it wrong and a signature that should have been valid isn't.

5. Voting rights and decision thresholds

Which decisions need a majority, which need unanimity? Selling the company, taking on debt, amending the agreement — spell out the big ones. Avoid 50/50 splits with no tiebreaker (see below).

6. Transfer restrictions

Can a member sell their interest to an outsider? Almost every good operating agreement restricts transfers and gives remaining members a right of first refusal. Without it, you could end up in business with a stranger.

7. Dissolution and exit

What triggers winding down the LLC? What happens to a member who wants out, dies, or is expelled? Build in a valuation mechanism (a formula or process) so a buyout doesn't become litigation.

8. Death or incapacity

Name a successor manager and define how the deceased member's interest passes. This is what keeps the business running instead of freezing in probate.

The 50/50 trap (and how to avoid it)

Equal ownership sounds fair but creates deadlock: any major decision can be blocked by one partner. Fix it one of three ways:

• Split 51/49 so there's a deciding vote
• Name one managing member with tiebreaker authority on operational decisions
• Add an arbitration or shotgun clause for unresolved disputes

State-specific note

A few states (notably California, Delaware, and New York) have quirks in their default LLC statutes — member fiduciary duties, charging orders, and dissolution rights vary. Your operating agreement overrides most defaults, but the override language has to be there. That's why a generic downloaded form often misses the mark: it isn't drafted for your state.

The honest truth about templates

A well-drafted operating agreement template gets you 90% of the way for most small and mid-size LLCs. The clauses above are standard and tested.

What a template does not give you: personalized tax advice (especially if you're electing S-corp treatment), help with complex multi-entity structures, or malpractice coverage if something's wrong. For a straightforward LLC, generate it, read it, and consider a quick attorney review before signing — especially for multi-member deals.
