What Is an LLC?

A Limited Liability Company (LLC) is the most popular business structure in the United States — combining the liability protection of a corporation with the tax flexibility and simplicity of a partnership.

Simple Definition

An LLC (Limited Liability Company) is a legal business structure that creates a separate entity from its owners (called “members”). This separation protects your personal assets — your home, car, savings, and personal property — from business debts, lawsuits, and liabilities. At the same time, profits and losses “pass through” directly to members, avoiding the double taxation that corporations face.

How an LLC Works

Understanding the core mechanics of an LLC helps you decide if it is the right structure for your business.

Limited Liability Protection

The defining feature of an LLC is limited liability. Because the LLC is a separate legal entity from its owners, members generally cannot be held personally responsible for the company’s debts, obligations, or legal judgments. If the business is sued or goes bankrupt, creditors can only pursue the assets of the LLC — not your personal bank account, home, or other property.

This protection is not absolute. Courts can “pierce the corporate veil” in cases of fraud, commingling of personal and business funds, or failure to follow legal formalities. Maintaining a clear separation between personal and business finances is essential.

Pass-Through Taxation

By default, the IRS treats an LLC as a pass-through entity. This means the LLC itself does not pay federal income tax. Instead, profits and losses are “passed through” to the members, who report them on their personal tax returns. This avoids the double taxation that C corporations face — where profits are taxed once at the corporate level and again as shareholder dividends.

Single-member LLCs are treated as “disregarded entities” (like sole proprietorships) for tax purposes. Multi-member LLCs are treated as partnerships. However, LLCs can also elect to be taxed as an S corporation or C corporation if that provides a tax advantage.

Flexible Management

LLCs offer unmatched management flexibility. Members can choose to manage the business themselves (member-managed) or appoint managers to handle day-to-day operations (manager-managed). There are no requirements for a board of directors, shareholder meetings, or extensive record-keeping like corporations require.

The internal rules of the LLC are governed by an Operating Agreement — a contract between members that outlines ownership percentages, profit distribution, voting rights, and procedures for adding or removing members. While not required in all states, an Operating Agreement is strongly recommended.

How to Form an LLC

Creating an LLC is straightforward and can be completed online in most states within a few days.

1

Choose a Name

Your LLC name must be unique in your state and include “LLC” or “Limited Liability Company.” Check availability through your Secretary of State’s website.

2

Appoint a Registered Agent

Every LLC needs a registered agent with a physical address in the state to receive legal documents and official notices on behalf of the business.

3

File Articles of Organization

Submit formation documents to your state along with the filing fee ($40–$500 depending on the state). This officially creates your LLC.

4

Create an Operating Agreement

Draft an internal document outlining ownership structure, member roles, profit distribution, and decision-making procedures.

5

Obtain an EIN

Apply for a free Employer Identification Number (EIN) from the IRS. This is your business’s federal tax ID, required for banking and taxes.

6

Open a Business Bank Account

Keep personal and business finances separate by opening a dedicated business bank account using your EIN and formation documents.

Important: State filing fees range from approximately $40 to $500. Some online formation services like Bizee offer free LLC formation — you only pay the state fee. Most states also require an annual or biennial report to keep your LLC in good standing.

Benefits and Drawbacks of an LLC

Every business structure has trade-offs. Here is what you need to know before choosing an LLC.

Personal Asset Protection

Your personal assets are shielded from business debts and lawsuits. Members’ liability is limited to their investment in the company.

Major Advantage

Pass-Through Taxation

Avoid double taxation. Profits flow directly to members and are taxed only once on personal returns, reducing overall tax burden.

Major Advantage

Management Flexibility

No board of directors, shareholder meetings, or complex corporate formalities required. Run the business how you see fit.

Major Advantage

Credibility & Professionalism

Operating as “Your Business, LLC” signals legitimacy to customers, vendors, lenders, and investors compared to a sole proprietorship.

Major Advantage

Tax Classification Options

Choose your tax treatment: default pass-through, S corp election, or C corp election. Optimize for your specific financial situation.

Major Advantage

Easy to Form & Maintain

Less paperwork and lower compliance costs than corporations. Most states require only a simple annual or biennial report.

Major Advantage

Self-Employment Taxes

Members must pay self-employment taxes (Social Security and Medicare) on their share of profits, which can be higher than corporate salary structures.

Consideration

Limited Life in Some States

Depending on state law, an LLC may need to be dissolved if a member dies, leaves, or files for bankruptcy unless the Operating Agreement specifies otherwise.

Consideration

Investor Limitations

Venture capitalists and some institutional investors prefer C corporations. LLCs cannot issue stock, making equity financing more complex.

Consideration

Varying State Rules

LLC regulations differ from state to state. If you operate in multiple states, you may need to register as a foreign LLC in each one.

Consideration

LLC vs. Other Business Structures

See how an LLC stacks up against sole proprietorships, partnerships, and corporations.

LLC vs. Sole Proprietorship

A sole proprietorship is the simplest business structure — there is no legal separation between you and the business. You have unlimited personal liability for all business debts and lawsuits. An LLC provides the same operational simplicity but adds a critical layer of personal asset protection. For most entrepreneurs, the small cost and effort of forming an LLC is worth the liability shield.

LLC vs. Partnership

A general partnership is similar to a sole proprietorship but with multiple owners. Like sole proprietorships, partners have unlimited personal liability — and each partner can be held responsible for the actions of the other partners. A multi-member LLC offers the same pass-through taxation as a partnership but limits each member’s liability to their investment in the business.

LLC vs. Corporation (C Corp & S Corp)

C corporations offer the strongest liability protection but face double taxation — profits are taxed at the corporate level and again as dividends to shareholders. They also require a board of directors, annual meetings, and extensive record-keeping.

S corporations avoid double taxation with pass-through treatment but have strict ownership restrictions (only U.S. citizens/residents, max 100 shareholders, one class of stock). LLCs offer more flexibility in ownership structure and profit allocation while still providing liability protection.

Types of LLCs

Not all LLCs are the same. Here are the most common variations you should know about.

Single-Member LLC

Owned by one person. Treated as a “disregarded entity” by the IRS (like a sole proprietorship) for tax purposes unless an election is made.

Multi-Member LLC

Owned by two or more members. Treated as a partnership by default for tax purposes. Requires more complex Operating Agreement.

Professional LLC (PLLC)

For licensed professionals (doctors, lawyers, accountants). Required in some states. All members must hold the same professional license.

Series LLC

Allows a single LLC to create separate “series” or cells, each with its own assets and liabilities. Useful for real estate investors with multiple properties.

Foreign LLC

An LLC formed in one state that registers to do business in another state. Required if you have a physical presence or significant business activity outside your home state.

L3C (Low-Profit LLC)

A hybrid structure for social enterprises that prioritizes a charitable or educational mission over profit maximization. Combines LLC flexibility with nonprofit-like goals.

Who Should Form an LLC?

An LLC is the right choice for most small businesses, but it is especially well-suited for these situations.

  • Small Business Owners & Freelancers

    If you operate a business with any risk of liability — from consulting to e-commerce to construction — an LLC protects your personal assets.

  • Real Estate Investors

    Holding rental properties in an LLC isolates liability for each property. Many investors use a separate LLC per property for maximum protection.

  • Online Businesses & E-Commerce

    Sellers on Amazon, Shopify, Etsy, and other platforms benefit from liability protection and the credibility of operating as a formal business entity.

  • Family Businesses

    A family LLC allows you to pool assets, share management responsibilities, and transfer ownership interests to heirs while maintaining liability protection.

  • Non-US Residents

    Foreign entrepreneurs can form a US LLC without being a citizen or resident. An LLC provides access to US payment processors, banking, and markets.

LLC Frequently Asked Questions

Do I need a lawyer to form an LLC?

No. In most states, you can form an LLC yourself by filing Articles of Organization with the Secretary of State. Online formation services like Bizee, LegalZoom, or Harbor Compliance handle the paperwork for you at a fraction of the cost of hiring an attorney. However, if your LLC has complex ownership structures or you need custom legal documents, consulting a business attorney is recommended.

Can I be my own registered agent?

Yes, in most states you can serve as your own registered agent if you have a physical address in the state where the LLC is formed and are available during business hours. However, most business owners hire a professional registered agent service for privacy (your address won’t be on public record) and reliability (ensuring you never miss important legal documents).

What is an Operating Agreement and do I need one?

An Operating Agreement is an internal document that governs how your LLC operates — covering ownership percentages, profit distribution, voting rights, member roles, and procedures for adding or removing members. While not required in all states, it is strongly recommended for all LLCs, especially multi-member ones. Banks often require it to open a business account, and it is essential for protecting your limited liability status.

Can a non-US resident form an LLC?

Yes. You do not need to be a US citizen or resident to form an LLC in the United States. You do not need a Social Security Number. Non-residents can obtain an EIN from the IRS and open a US business bank account remotely through fintech platforms like Mercury or Relay. Services like Doola and StartGlobal specialize in helping international entrepreneurs form US LLCs.

What happens if I do not maintain my LLC?

If you fail to file required annual reports, pay state fees, or maintain a registered agent, your state may administratively dissolve your LLC or place it in “bad standing.” This means you lose liability protection, cannot legally conduct business in the state, and may face penalties. Harbor Compliance and similar services offer automated compliance tracking to prevent this.
