LLC operating agreement

What an operating agreement is

An LLC operating agreement is a private, written contract among the members of a limited liability company. It overrides your state's default LLC rules — the boilerplate the legislature wrote for owners who never bothered to put anything in writing. Those defaults are rarely what real members want: equal voting regardless of contribution, pro-rata distributions with no exceptions, automatic dissolution on a member's death. An operating agreement replaces those defaults with terms you actually chose.

The document is not filed with the state. It lives in your records with the rest of your governance paperwork — minutes, EIN letter, articles, K-1s — and is shown to banks, the IRS, lenders, and eventually to lawyers if a dispute or sale comes up.

Who needs one (and where it's legally required)

Five states require LLCs to adopt a written operating agreement: California, Delaware, Maine, Missouri, and New York. New York is the strictest — it has to be adopted within 90 days of filing the Articles of Organization. In every other state it's not legally required, but it's required in practice: most banks will not open a business account without one, and any serious investor, lender, or co-founder will insist on it.

Single-member vs multi-member

Single-member

Shorter and simpler. It focuses on three things: confirming the LLC is a separate entity, defining what happens if you become incapacitated or die, and declaring tax classification (disregarded entity by default; S-corp by election).

Multi-member

Longer and far more important. Every dispute between members eventually traces back to this document. It needs to cover capital contributions, profit and loss allocations (which can differ from ownership percentages), voting thresholds, transfer restrictions, deadlock resolution, buy-out triggers and pricing formulas, drag-along and tag-along rights, and the full set of dissolution mechanics.

Clauses to include

Capital contributions & allocations

Capital contributions are what each member puts into the LLC at formation — cash, equipment, IP, real estate, or services. The operating agreement should record each contribution at its fair value, the date it was made, and the ownership % it bought. Without this written record, the IRS will treat your initial basis as zero, which becomes a tax problem the first time the LLC takes a loss or distributes property.

Allocations of profit and loss can — and often should — diverge from ownership %. A founder who contributes IP plus sweat equity might own 60% but take 80% of the first $200k of distributions until a preferred return is paid. A "special allocation" like this is valid under IRS rules as long as it has substantial economic effect; the agreement is where you write it down. Skip this and the IRS reallocates by ownership %, which is almost never what the members actually agreed to.

Capital calls

If the LLC may need more money later, decide now whether members are obligated to contribute on call, optional to contribute, or diluted if they pass. Capital-call disputes are one of the most common reasons multi-member LLCs end up in court.

Member-managed vs manager-managed

Member-managed is the default in almost every state: every member has authority to bind the LLC and run day-to-day operations. It works for small, tight-knit teams where everyone is involved.

Manager-managed separates ownership from control. One or more managers (who may or may not be members) run operations; the other members are passive investors with voting rights only on major decisions. Choose this if you have silent investors, family members holding equity, or anyone you don't want signing contracts on the LLC's behalf.

Template vs lawyer

A free or paid template is fine for a clean single-member LLC where you own 100% and the structure is unlikely to change. For anything more complicated — multiple founders, outside capital, vesting, different equity classes, custom profit splits, or anyone with negotiation leverage at the table — get a lawyer to draft or at least review the agreement. The cost is small compared to the cost of the dispute it prevents.

Red flags in a template

• No buy-out formula or trigger events
• No mechanism to resolve a 50/50 deadlock
• Vague distribution language ("as the members agree from time to time")
• No process for adding or removing members

Signing, storing & sharing it

The operating agreement takes effect when every member signs it — wet signature or e-signature both work in all 50 states. Date it the same day or after the Articles of Organization are filed; in New York, finish within 90 days of formation to meet the statutory deadline. Keep the signed original (or signed PDF) in your company records alongside the EIN letter, Articles, and any amendments. Banks will ask for a copy when you open the business account; the IRS may request it during an audit; investors will want it during diligence. You don't need to record it anywhere public.

How to amend it

Every well-drafted operating agreement contains an amendment clause specifying what vote is required to change it — usually majority for ordinary matters and unanimous for things that change a member's economic rights. When you amend, do it in writing, get signatures, and store the amendment with the original agreement. Never rely on email threads or verbal agreements to modify how money or control is allocated.

Operating agreement & S-corp election

If your LLC elects S-corp tax treatment (Form 2553), the operating agreement has to be S-corp compatible. S-corp rules require a single class of stock — meaning every member has identical rights to distributions and liquidation proceeds. Special allocations that are legal for a default LLC will blow the S-corp election. If you're planning an S-corp election now or later, draft the agreement with strict pro-rata distributions and add a clause prohibiting any amendment that would create a second class of equity. Otherwise an innocent change two years from now silently terminates your S-corp status.

Common mistakes

• Skipping it because it isn't required

  Your state may not require it, but your bank, the IRS, and any future buyer will.

• Using a single-member template for a multi-member LLC

  There is no language for deadlock, transfers, or buy-out — the exact moments you need it most.

• Never updating it

  If members, ownership, or tax election change, the agreement has to change too. Stale agreements cause real disputes.

• Verbal side deals

  Anything that contradicts the written agreement gets ignored by a court. Put every change in writing.
