LLC

LLCs are among the most widely used business entities in the United States. The U.S. Census Bureau tracks tens of thousands of new business applications each month, particularly among small business owners, freelancers, and entrepreneurs seeking formal legal protection without the administrative complexity of a corporation.

How an LLC works

An LLC is formed at the state level by filing a document called the articles of organization with the appropriate state agency, typically the Secretary of State. Once approved, the LLC becomes a legally distinct entity, separate from its owners, who are referred to as members.

Because the LLC is its own legal entity, it can enter into contracts, open bank accounts, take on debt, and be sued, all in its own name rather than in the name of its members. This separation is the foundation of the liability protection an LLC provides.

Most LLCs are also required or strongly advised to adopt an operating agreement, a governing document that outlines the ownership structure, management responsibilities, profit distribution, and procedures for adding or removing members.

To form an LLC, owners generally follow these steps.

1. Choose a business name that complies with state naming rules
2. Designate a registered agent to receive legal notices on behalf of the business
3. File articles of organization with the state and pay the required filing fee
4. Draft an operating agreement
5. Obtain an Employer Identification Number (EIN) from the IRS; the application is free and issued immediately online
6. Apply for any required business licenses or permits

Why an LLC matters

The primary reason business owners form an LLC is to protect against personal liability. If the business is sued or cannot pay its debts, the members' personal assets, such as a home, personal bank accounts, or personal property, are generally shielded from collection. Without this protection, a sole proprietor or general partner is personally responsible for all business obligations.

Beyond liability protection, an LLC offers meaningful tax flexibility. By default, a single-member LLC is taxed as a sole proprietorship, and a multi-member LLC is taxed as a partnership, meaning profits pass through to members' personal tax returns without being taxed at the entity level first. Members can also elect to have the LLC treated as a corporation or be taxed as an S corporation if that structure is more advantageous.

LLCs also carry practical benefits: they can help establish business credibility with banks, vendors, and clients; they make it easier to open a dedicated business bank account; and they provide a clear legal framework for entering contracts and hiring employees.

Common uses and examples of an LLC

LLCs are used across a wide range of industries and business types. Common examples include:

• Freelancers and consultants. Freelancers and consultants often form a single-member LLC to separate personal finances from client work and reduce personal liability exposure.
• Real estate investors. Real estate investors are the ones who hold rental properties inside an LLC to protect personal assets from tenant lawsuits or property-related claims.
• Small retail or service businesses. Small retail or service businesses include a restaurant, salon, or landscaping company that forms an LLC to operate as a recognized legal entity.
• Business partners. Business partners form a multi-member LLC to define ownership percentages, profit-sharing, and decision-making authority within a formal structure.

A single-member LLC is appropriate for a solo owner, while a multi-member LLC accommodates two or more owners. In certain licensed professions, such as law, medicine, or accounting, a professional LLC may be required instead of a standard LLC.

Key characteristics of an LLC

Several defining features distinguish an LLC from other business structures.

• Limited liability protection: Members are generally not personally responsible for the LLC's debts or legal judgments.
• Pass-through taxation (by default): Business income is reported on members' personal tax returns, avoiding the double taxation that can apply to C corporations.
• Flexible management structure: An LLC can be managed either directly by its members (member-managed) or by appointed managers (manager-managed), without the formal board and officer requirements of a corporation.
• Minimal formalities: Unlike corporations, LLCs are not required to hold annual shareholder meetings or maintain detailed meeting minutes.
• Operating agreement customization: Members can tailor the operating agreement to fit their specific business needs, within the limits of state law.

LLC vs. sole proprietorship

A sole proprietorship is the default structure for an individual operating a business without formal registration. It requires no filing and has no setup cost, but it provides no liability protection; the owner and the business are legally the same entity.

An LLC, by contrast, requires state registration and ongoing compliance but creates a legal separation between the owner and the business. For most business owners facing meaningful financial or legal risk, the liability protection of an LLC outweighs the additional administrative requirements.

Considerations and limitations

LLC rules vary by state. Filing fees, annual report requirements, and ongoing compliance obligations vary by jurisdiction; for example, the New York LLC Transparency Act took effect on January 1, 2026, imposing new disclosure requirements on LLCs formed or operating in the state. At the federal level, domestic LLCs are now exempt from beneficial ownership reporting requirements under a 2025 interim final rule from FinCEN, though state-level obligations may still apply.

Some states charge higher fees or impose additional taxes on LLCs; California, for example, levies a $800 minimum annual franchise tax on LLCs doing business in the state.

Liability protection is not absolute. Courts can "pierce the corporate veil" and hold members personally liable if the LLC is not treated as a separate entity, for instance, if members commingle personal and business funds or fail to maintain basic formalities.

An LLC formed in one state that operates in another may need to register as a foreign LLC in that additional state, which involves a separate filing and fee, and may be subject to independent state-level reporting laws in that jurisdiction.

Certain business types, including banks and insurance companies, are generally prohibited from operating as LLCs under state or federal law.

Related terms and next steps

Understanding what an LLC is connects directly to several related concepts that govern how LLCs are structured and operated.

• Operating agreement for an LLC: The internal document that defines how the LLC is governed, how profits are distributed, and how decisions are made
• Single-member LLC: An LLC with one owner; taxed as a sole proprietorship by default
• Multi-member LLC: An LLC with two or more owners; taxed as a partnership by default
• Professional LLC: A specialized LLC structure for licensed professionals in certain fields
• Foreign LLC: An LLC registered to do business in a state other than the one where it was originally formed
• Series LLC: A structure available in some states that allows a single LLC to create separate liability "cells" for different assets or business lines

For those ready to move from understanding to action, forming an LLC begins with filing articles of organization in the appropriate state. LegalZoom assists with LLC formation filings in all 50 states, as well as operating agreement preparation and EIN registration.

FAQs about LLCs

How is an LLC taxed if it has multiple owners?

A multi-member LLC is taxed as a partnership by default. The LLC itself files Form 1065 with the IRS, and each member receives a Schedule K-1 reporting their share of the profits or losses, which they then report on their personal tax returns. Members can elect out of this default treatment by filing Form 8832 to be taxed as a C corporation, or Form 2553 to be taxed as an S corporation, if a different structure is more advantageous for their situation.

Can an LLC lose its liability protection?

Yes, courts can "pierce the corporate veil" and hold members personally liable if the LLC is not consistently treated as a separate legal entity, most commonly when members commingle personal and business funds, use the LLC to commit fraud, or fail to maintain the basic formalities the structure requires. Keeping a dedicated business bank account, signing contracts in the LLC's name rather than your own, and maintaining a current operating agreement are among the most effective ways to preserve that separation.

What is the downside of forming an LLC compared to staying a sole proprietor?

An LLC costs more to form and maintain; state filing fees, annual report requirements, and in some states significant ongoing taxes (California's $800 minimum franchise tax being the most cited example) add up in ways a sole proprietorship simply does not. Members also generally owe self-employment taxes on their share of LLC income, and because an LLC cannot issue stock, raising capital from institutional investors or venture capital is more difficult than it would be through a C corporation.

Does an LLC need an operating agreement?

Not every state legally requires one, but operating without an operating agreement means the LLC's governance defaults to state rules, which may not reflect how the members actually want to divide profits, make decisions, or handle a member's departure. For a multi-member LLC in particular, a written operating agreement is the primary document that prevents disputes from escalating into litigation.

When does an LLC formed in one state need to register in another state?

An LLC generally needs to register as a foreign LLC in any state where it has a physical presence, employees, or conducts regular business activity, not just where it was originally formed. Each state defines "doing business" slightly differently, but the registration requirement typically triggers a filing fee, a registered agent obligation, and potentially additional state-level tax and reporting requirements in that jurisdiction.
