Why Your LLC Needs an Operating Agreement (Even If You're the Only Member)

You Filed Your LLC. Congratulations. You’re Not Done.

Filing articles of organization with your state gets you an LLC. But without an operating agreement, you’ve built a house without a foundation. It might look fine from the outside, but the first strong wind --- a lawsuit, a dispute, a tax audit --- will expose the gaps.

An operating agreement is an internal document that defines how your LLC operates. Who makes decisions, how profits are split, what happens if a member leaves, and dozens of other questions that seem irrelevant right now but become critically important later.

Here’s the part that surprises most people: even single-member LLCs need one. Let me explain why.

The Solo Founder Problem

“I’m the only member. I make all the decisions. Why do I need an agreement with myself?”

Three reasons, and they’re all serious:

1. Protecting Your Personal Assets

The entire point of an LLC is the liability shield --- keeping your personal assets (house, car, savings) separate from business debts. But that shield isn’t automatic. Courts can “pierce the corporate veil” and hold you personally liable if they determine that you and your LLC are essentially the same thing.

One of the key factors courts look at? Whether the LLC has a formal operating agreement. Without one, it’s easier for a plaintiff’s attorney to argue that your LLC is just a shell --- that you don’t really treat it as a separate entity.

A solo founder in Colorado learned this the hard way when a contractor sued his LLC for $180,000. The court pierced the veil because, among other things, there was no operating agreement, business and personal funds were commingled, and no formal records were maintained. He was personally liable for the full judgment.

2. Banks and Partners Require It

Try opening a business bank account without an operating agreement. Many banks will turn you away. They want to see who’s authorized to manage the account and sign on behalf of the LLC.

The same goes for business loans, lines of credit, commercial leases, and partnership agreements. The operating agreement is your proof that your LLC is a real business entity with defined governance.

3. Default State Rules Might Not Work for You

Every state has a default LLC statute that fills in the gaps when you don’t have an operating agreement. The problem is, those default rules might not match what you want.

For example, many states default to equal profit distribution among members. If you and a partner own 70/30 but have no operating agreement, the state says you split profits 50/50. Some states allow members to withdraw capital without other members’ consent under default rules. Others have mandatory dissolution provisions that trigger when a member dies or leaves.

An operating agreement overrides these defaults with your actual intentions.

What Goes in an Operating Agreement

Organizational Details

LLC name and principal address
Date of formation and state of formation
Purpose of the LLC (keep this broad: “any lawful business activity”)
Registered agent information
Duration (most LLCs are perpetual, but some are formed for specific projects)

Membership and Ownership

For single-member LLCs: Your name, your ownership percentage (100%), and your initial capital contribution.

For multi-member LLCs: This is where it gets important:

Each member’s name and ownership percentage
Initial capital contributions (cash, property, services) and their agreed values
Future capital contribution requirements
Whether membership interests can be transferred and under what conditions
Process for admitting new members

The capital contribution section matters more than people realize. A partnership where one person contributes $100,000 in cash and another contributes “sweat equity” valued at $100,000 needs to document those contributions clearly. What counts as sweat equity? When is it fully vested? What if the sweat equity partner leaves after six months?

Management Structure

LLCs are either member-managed or manager-managed:

Member-managed: All members participate in day-to-day operations and decisions. This is common for small LLCs where everyone is actively involved. Think two co-founders running a business together.

Manager-managed: One or more designated managers (who may or may not be members) handle daily operations. Other members are passive investors. This is common for LLCs with investors who don’t want operational involvement, real estate LLCs, or larger organizations.

Your operating agreement should specify:

Which management structure you’re using
What decisions managers can make unilaterally
What decisions require member votes
Voting thresholds (majority, supermajority, unanimous) for different types of decisions
Whether managers are compensated and how

Profit and Loss Distribution

How are profits (and losses) divided among members? Options include:

Pro rata by ownership percentage (the most common approach)
Special allocations that differ from ownership percentages (must have “substantial economic effect” to satisfy IRS rules)
Preferred returns where certain members get paid first up to a specified percentage before profits are split
Distribution schedules (quarterly, annually, at manager’s discretion)

Also address: Are members guaranteed distributions, or are they at the discretion of management? Can the LLC retain profits for reinvestment? What’s the minimum distribution needed to cover members’ tax obligations (this is important because LLC members pay taxes on their share of profits even if they don’t receive distributions)?

Tax Elections

LLCs have flexibility in how they’re taxed. Your operating agreement should document:

Whether the LLC elects to be taxed as a disregarded entity (single-member default), partnership (multi-member default), S corporation, or C corporation
Tax year (calendar vs fiscal)
Responsibility for maintaining tax records
Who the “Tax Matters Partner” is (the member who deals with the IRS on the LLC’s behalf)

The S corp election is particularly relevant for profitable single-member LLCs. By electing S corp taxation, a solo founder who earns $200,000 in profit can pay herself a “reasonable salary” of, say, $100,000 and take the remaining $100,000 as a distribution --- avoiding self-employment tax on the distribution portion. That can save $15,000+ per year. Your operating agreement should document whatever tax election you make.

Transfer Restrictions and Buy-Sell Provisions

What happens when a member wants out? Multi-member operating agreements should address:

Right of first refusal. Before a member can sell their interest to an outsider, they must offer it to existing members at the same terms.

Valuation method. How is the departing member’s interest valued? Options include: agreed fixed value (updated periodically), book value, appraised value by an independent third party, or a formula (like a multiple of earnings).

Payment terms. Can the LLC buy out a departing member’s interest? Over what period? Lump sum or installments?

Drag-along and tag-along rights. If a majority member sells, can they force minority members to sell too (drag-along)? If a majority member gets an offer, do minority members have the right to participate at the same terms (tag-along)?

Death, Disability, and Dissolution

Nobody wants to think about this, but a good operating agreement covers:

What happens to a member’s interest if they die (does it pass to their estate, or do surviving members have a buyout option?)
What happens if a member becomes permanently disabled
What triggers dissolution of the LLC (unanimous vote, a specific event, bankruptcy)
The process for winding down the business and distributing assets

Without these provisions, a member’s death can force the dissolution of the entire LLC under default state law. That’s clearly not what most business owners want.

Meetings and Records

Even if your LLC never holds a formal meeting, having provisions for:

Annual member meetings (at minimum)
How meetings are called and how much notice is required
Quorum requirements
Record-keeping responsibilities
Inspection rights (members’ rights to access LLC books and records)

This section reinforces that your LLC is a real, functioning business entity --- which circles back to protecting that liability shield.

The Solo Founder Checklist

If you’re a single-member LLC, your operating agreement doesn’t need to be 30 pages. But it should cover:

Your name and ownership (100%)
Initial capital contribution
That you are the sole manager with full authority
How profits are distributed (to you, on your schedule)
Tax election (disregarded entity or S corp)
What happens to the LLC if you become incapacitated or die
That the LLC is a separate entity from you personally
Amendment process (you can change it anytime, in writing)

Our LLC Operating Agreement Generator handles all of this --- whether you’re a solo founder or have multiple members. It walks through each section and generates a document you can use immediately or bring to an attorney for review.

Don’t Let “Later” Become “Too Late”

I’ve watched two co-founders spend $75,000 in legal fees fighting over a $300,000 business because they never wrote down how to handle a split. Their verbal agreement about 60/40 ownership and who had decision-making authority was worth exactly nothing when the relationship deteriorated.

An operating agreement takes an afternoon to create. The disputes it prevents can take years and tens of thousands of dollars to resolve. This is one of those documents where the cost of not having it is always, always higher than the cost of having it.
