Two Documents, Two Entity Types
One of the most common points of confusion for new business owners is the difference between an LLC operating agreement and corporate bylaws. While both serve as internal governance documents, they apply to different types of business entities and function in distinct ways.
The short version: LLCs use operating agreements. Corporations use bylaws. They're not interchangeable, and using the wrong one can create legal and administrative problems for your business.
What Is an LLC Operating Agreement?
An LLC operating agreement is the governing document for a limited liability company. It defines:
- Ownership percentages and capital contributions
- How profits and losses are distributed
- Management structure (member-managed vs. manager-managed)
- Voting rights and decision-making procedures
- Rules for transferring membership interests
- Dissolution and winding-up procedures
Operating agreements are highly flexible. Unlike corporate bylaws, which must follow certain statutory frameworks, LLC operating agreements allow members to customize virtually every aspect of how the business operates.
What Are Corporate Bylaws?
Corporate bylaws are the internal rules that govern how a corporation operates. They typically cover:
- Board of directors structure, election procedures, and responsibilities
- Officer positions and duties
- Shareholder meeting procedures and voting rights
- Stock issuance and transfer rules
- Dividend policies
- Amendment procedures
Bylaws must conform to the corporation's articles of incorporation and the state's business corporation act. There's less room for customization compared to LLC operating agreements.
Key Differences Between Operating Agreements and Bylaws
Flexibility
This is the most significant difference. LLC operating agreements offer far greater flexibility than corporate bylaws.
Operating agreements let members create virtually any arrangement they want for profit sharing, management, voting, and more. Members can agree to split profits differently from ownership percentages, create tiered voting structures, or design unique management hierarchies.
Bylaws must operate within the rigid framework of corporate law. Corporations have mandatory structures — a board of directors, officers, shareholders — and bylaws must work within those constraints.
The flexibility of LLC operating agreements is one of the primary reasons many small businesses and startups choose the LLC structure. You can design governance rules that fit your specific situation rather than conforming to a statutory framework.
Tax Treatment
Operating agreements can specify the LLC's tax election (disregarded entity, partnership, S-corp, or C-corp) and define how tax-related decisions are made. This flexibility in tax treatment is a major advantage of LLCs.
Bylaws don't typically address tax elections because corporations have a fixed tax structure (C-corp by default, with the option to elect S-corp status through IRS Form 2553).
Management Structure
Operating agreements allow LLCs to choose between member-managed and manager-managed structures. In a member-managed LLC, all members participate in day-to-day operations. In a manager-managed LLC, designated managers (who may or may not be members) handle operations while other members act more like passive investors.
Bylaws establish a mandatory three-tier structure: shareholders (owners), the board of directors (oversight), and officers (day-to-day management). Every corporation must have this structure, though in small corporations, the same person can fill multiple roles.
Ownership Documentation
In an LLC, the operating agreement itself documents ownership. It lists members, their ownership percentages, and their capital contributions. Changes in ownership are reflected by amending the operating agreement.
In a corporation, ownership is documented through stock certificates and a stock ledger, not the bylaws. The bylaws establish the rules for issuing and transferring stock, but the actual ownership records are maintained separately.
Formality Requirements
Operating agreements generally don't need to be filed with the state (though they must be kept with company records). They can be amended through whatever process the agreement itself specifies, which could be as simple as a majority vote of the members.
Bylaws typically come with more formal requirements. Many states require that bylaw amendments be documented in corporate minutes, approved by the board of directors or shareholders, and maintained in the corporate records book.
Profit Distribution
Operating agreements can establish any profit distribution scheme the members agree to. Profits don't have to follow ownership percentages. For example, a member who owns 30% of the LLC could receive 50% of the profits if the members agree to that arrangement (though this has tax implications that should be considered).
Bylaws establish dividend policies, but dividends must be distributed proportionally to share ownership within each class of stock. A shareholder who owns 30% of common stock receives 30% of the common stock dividends — no exceptions.
Which One Does Your Business Need?
The answer depends entirely on your business entity type:
| Feature | LLC | Corporation |
|---|---|---|
| Governing document | Operating agreement | Bylaws |
| Flexibility | High | Moderate |
| Management options | Member or manager-managed | Board + officers required |
| Profit distribution | Customizable | Proportional to shares |
| Tax flexibility | Multiple elections available | C-corp or S-corp |
| Formality level | Lower | Higher |
Choose an LLC (and Operating Agreement) If:
- You want maximum flexibility in structuring ownership and profit sharing
- You prefer a simpler management structure
- You want to avoid the formalities of corporate governance
- Tax flexibility is important to you
- You have a small number of owners who are actively involved in the business
Choose a Corporation (and Bylaws) If:
- You plan to seek venture capital or go public (investors typically prefer C-corps)
- You want a well-established governance framework
- You need to issue different classes of stock
- You plan to offer stock options to employees
If you've already formed an LLC, you need an operating agreement — not bylaws. Using the wrong document type can create confusion and may not provide the legal protections your entity type requires.
Can an LLC Have Bylaws?
Technically, nothing prevents an LLC from adopting bylaws-like rules. However, this is unusual and potentially confusing. The standard practice — and what banks, courts, and business partners expect — is for LLCs to have operating agreements.
Using the term "bylaws" for an LLC document could create confusion about your entity type, potentially complicating interactions with financial institutions, partners, or in legal proceedings. Stick with an operating agreement for your LLC.
The Practical Takeaway
If you've formed an LLC, your next step is creating an operating agreement that reflects your business structure, member arrangements, and operational procedures. It's the document that gives your LLC its internal rules and protects all members' interests.
Don't confuse operating agreements with bylaws, and don't try to use a corporate bylaws template for your LLC. The two serve different entity types with different legal frameworks, and using the right document matters.
