What is an LLC?

A limited liability company (LLC) is one of the most popular business structures for small business owners in the US. Here's what it means and why it matters for your business.

An LLC is a legal business structure that separates your personal assets, like your home and savings, from your business obligations. If your business faces a lawsuit or can't pay its debts, your personal property is generally protected. The IRS classifies LLCs as a flexible entity that can be taxed in several different ways depending on how many members (owners) are involved.

You can form an LLC on your own as a single-member LLC, or with one or more partners as a multi-member LLC. Both types offer the same core benefit of limited liability protection, but they differ in how the IRS treats them for tax purposes.

Types of LLCs

LLCs come in different forms depending on how many owners are involved. Understanding the difference helps you choose the right setup and know what to expect at tax time.

Single-member LLCs

A single-member LLC has one owner. By default, the IRS treats a single-member LLC as a "disregarded entity," which means you report your business income and expenses on your personal tax return using Schedule C. You don't need to file a separate business tax return unless you elect a different tax classification.

Multi-member LLCs

A multi-member LLC has two or more owners. The IRS treats it as a partnership by default, which means the LLC itself doesn't pay income tax. Instead, profits and losses pass through to each member's personal tax return based on their ownership percentage. The LLC files an informational return (Form 1065) so the IRS can see how income is distributed.

LLC management structures

How your LLC is managed day to day depends on the structure you choose. Your operating agreement should spell out which management structure you're using and how decisions get made.

Member-managed LLCs

In a member-managed LLC, all owners share responsibility for running the business. Each member can make decisions, sign contracts, and handle daily operations. This structure works well for small businesses where every owner is actively involved.

Manager-managed LLCs

In a manager-managed LLC, one or more designated managers handle business operations while other members take a more passive role. The manager can be a member or an outside hire. This structure is a good fit when some owners prefer to invest without managing daily operations, or when you want to bring in professional management.

Pros of an LLC

LLCs offer several advantages that make them a popular choice for small business owners. Here are the key benefits to consider.

Personal asset protection

The biggest advantage of an LLC is limited liability protection. Your personal assets, including your home, car, and savings, are generally shielded from business debts and lawsuits. If your business faces a legal claim or can't pay its obligations, creditors typically can't come after your personal property.

Tax flexibility

LLCs don't have a fixed tax classification. You can choose to be taxed as a sole proprietorship, partnership, S-corp, or C-corp depending on what saves you the most money. This flexibility lets you adjust your tax strategy as your business grows and your financial situation changes.

Ownership flexibility

There's no limit on how many members an LLC can have, and members can be individuals, other LLCs, or corporations. You also have freedom to split profits and losses however you agree, rather than being locked into a distribution based strictly on ownership percentage. This makes it easier to structure deals that work for everyone involved.

Cons of an LLC

While LLCs have many benefits, they also come with some drawbacks worth considering before you file.

More complex setup than a sole proprietorship

Forming an LLC requires filing paperwork with your state, paying filing fees (typically $50 to $500), and creating an operating agreement. A sole proprietorship, by comparison, has almost no formal setup requirements. You'll also need to maintain your LLC by filing annual reports and paying any recurring state fees.

Harder to attract investors

If you're planning to raise capital from venture capitalists or angel investors, an LLC may not be the best fit. Most investors prefer to work with C-corps because of the stock structures and governance frameworks they're familiar with. Converting from an LLC to a corporation later is possible but involves legal and tax complexity.

Self-employment tax

LLC members who actively work in the business typically pay self-employment tax (15.3%) on their share of the profits, covering Social Security and Medicare. This is higher than what corporate employees pay because you're responsible for both the employer and employee portions. Electing S-corp tax status can help reduce this burden for some business owners.

How LLCs are taxed

One of the biggest advantages of an LLC is tax flexibility. The IRS lets you choose from 4 tax classifications, so you can pick the one that works best for your situation.

Sole proprietorship (default for single-member LLCs)

If you're the only owner, the IRS automatically treats your LLC as a sole proprietorship. All business income flows to your personal tax return on Schedule C. This is the simplest option, but you'll pay self-employment tax on all net earnings.

Partnership (default for multi-member LLCs)

Multi-member LLCs are taxed as partnerships by default. The LLC files Form 1065 as an informational return, and each member receives a Schedule K-1 showing their share of income, deductions, and credits. Members then report this on their individual tax returns.

S-corp election

You can elect S-corp tax status by filing IRS Form 2553. With this election, you pay yourself a reasonable salary (subject to payroll taxes), and any remaining profits pass through as distributions that aren't subject to self-employment tax. This can reduce your overall tax bill if your LLC generates significant profit beyond a reasonable salary. Learn more about the differences in this S-corp vs LLC comparison.

C-corp election

You can also elect C-corp tax status by filing IRS Form 8832. This means your LLC pays corporate income tax (21% federal rate) on its profits, and any dividends paid to members are taxed again on their personal returns. While this creates double taxation, it can benefit businesses that want to reinvest profits at the lower corporate rate or plan to go public.

How to form an LLC

Setting up an LLC involves several steps, but the process is straightforward when you know what to expect. For a more detailed walkthrough, check out this guide on starting an LLC.

1. Choose and register your business name. Pick a unique name that complies with your state's naming rules. Most states require the name to include "LLC" or "Limited Liability Company." Search your state's business name database to confirm it's available.
2. Designate a registered agent. Every LLC needs a registered agent, which is a person or service authorized to receive legal documents on your behalf. Your registered agent must have a physical address in the state where your LLC is formed.
3. File articles of organization. Submit your articles of organization (called a certificate of formation in some states) with your state's business filing office. Filing fees typically range from $50 to $500 depending on the state.
4. Create an operating agreement. While not required in every state, an operating agreement outlines how your LLC will be managed, how profits are distributed, and what happens if a member leaves. Having one in place protects all members and prevents disputes.
5. Get an Employer Identification Number (EIN). Apply for a free EIN from the IRS. You'll need this to open a business bank account, hire employees, and file taxes. You can apply online and receive your EIN immediately.
6. Understand ongoing requirements. Research your state's requirements for annual reports, franchise taxes, and business licenses. You'll also want to open a business bank account to keep your personal and business finances separate.

LLC compliance and ongoing requirements

Forming your LLC is just the first step. Staying compliant with state regulations keeps your business in good standing and protects your limited liability status.

Most states require LLCs to file an annual or biennial report, which updates the state on your business address, members, and registered agent. Filing fees for annual reports typically range from $0 to $300 depending on the state. Missing a filing deadline can result in late fees or even administrative dissolution of your LLC.

Some states also charge an annual franchise tax or LLC tax regardless of whether your business earned a profit. California, for example, charges an $800 annual franchise tax for LLCs. Check your state's requirements so you're not caught off guard.

Keep your operating agreement up to date, maintain a separate business bank account, and hold onto records of major business decisions. These practices help reinforce the legal separation between you and your LLC, which is what protects your personal assets.

LLCs vs other business structures

Choosing the right business structure affects your taxes, liability, and how you run your business. Here's how LLCs compare to other common options. For more details, the SBA's business structure guide is a helpful resource.

LLC vs sole proprietorship

A sole proprietorship is the simplest business structure, but it doesn't separate your personal and business assets. Here's how the two compare:

• Liability: An LLC protects your personal assets from business debts. A sole proprietorship does not
• Setup: A sole proprietorship has no filing requirements. An LLC requires state registration and filing fees
• Taxes: Both are taxed as pass-through entities by default, but an LLC can elect S-corp or C-corp status
• Credibility: An LLC can appear more professional to clients, vendors, and lenders

LLC vs partnership

A general partnership is similar to a multi-member LLC in that profits pass through to the owners. The key differences come down to liability and flexibility:

• Liability: Partners in a general partnership are personally liable for business debts. LLC members are not
• Management: Partnerships don't require a formal operating agreement (though having one is smart). LLCs benefit from having one in place
• Taxes: Both default to pass-through taxation, but an LLC can elect corporate tax status
• Formality: An LLC requires state filing. A general partnership can exist without any formal registration

LLC vs corporation

Corporations offer liability protection like LLCs but come with more formalities. Here are the main differences:

• Structure: Corporations require a board of directors, officers, and formal meetings. LLCs have fewer governance requirements
• Taxes: C-corps face double taxation (corporate tax plus dividend tax). LLCs avoid this with pass-through taxation by default
• Fundraising: Corporations can issue stock, making it easier to attract investors. LLCs sell membership interests, which are less familiar to investors
• Flexibility: LLCs offer more flexibility in profit distribution and management structure

FAQs on LLCs

Here are some frequently asked questions about LLCs to help you make an informed decision about your business structure.

Do I need an LLC for my business?

You don't legally need an LLC to run a business, but forming one can protect your personal assets from business liabilities. If your business involves any financial risk, contracts with clients, or potential legal exposure, an LLC is worth considering.

How much does it cost to form an LLC?

State filing fees for articles of organization typically range from $50 to $500. You may also have additional costs for a registered agent service, operating agreement preparation, and any required business licenses or permits.

How long does it take to set up an LLC?

Processing times vary by state, but most LLC filings are approved within one to two weeks. Some states offer expedited processing for an additional fee, which can reduce the wait to a few business days.

Do I need a registered agent for an LLC?

Yes, every state requires LLCs to have a registered agent with a physical address in the state of formation. You can serve as your own registered agent, or you can hire a registered agent service for an annual fee typically ranging from $50 to $300.

What is the purpose of an LLC?

The primary purpose of an LLC is to separate your personal finances from your business obligations. This limited liability protection means your personal assets are generally shielded if your business faces lawsuits or can't pay its debts.

How does LLC taxation work?

The IRS doesn't have a specific LLC tax classification. Instead, LLCs choose how they want to be taxed: as a sole proprietorship, partnership, S-corp, or C-corp. Single-member LLCs default to sole proprietorship taxation, while multi-member LLCs default to partnership taxation. You can change your classification by filing the appropriate IRS forms.
