LLC vs. corporation: Key differences explained

A limited liability company (LLC) and a corporation are state-law business structures that can generally help protect owners' personal assets from business debts. They differ in taxation, management, ownership, ongoing requirements, and fundraising options. The right choice depends on your business plans, ownership structure, state law, and tax circumstances.

What is an LLC?

An LLC is a business entity that generally provides limited liability protection to its owners, who are called members. In many cases, members are not personally liable for the LLC's debts or legal claims. That protection is not absolute: personal guarantees, misconduct, failure to keep business and personal affairs separate, and other circumstances can create personal exposure.

For federal income tax purposes, an LLC's default treatment depends on its number of members. A single-member LLC is generally disregarded as separate from its owner, while a domestic LLC with two or more members is generally treated as a partnership. An LLC can also elect corporate tax treatment. Under the default treatment, income generally passes through to the owners' tax returns rather than being taxed at the entity level.

How to form an LLC

To form an LLC, business owners generally file articles of organization, or a similarly named formation document, with the appropriate state agency. The required information varies by state.

An operating agreement is a private document that can set out ownership interests, management responsibilities, profit and loss allocations, and decision-making rules. It is strongly recommended for most LLCs, although whether it is legally required depends on the state.

LLCs can be member-managed, where members handle day-to-day operations, or manager-managed, where appointed managers run the business. This flexibility can suit businesses that want to tailor their management structure to their owners and operations.

LLC compliance requirements

LLCs often have fewer formal governance requirements than corporations, but requirements vary by state and by the LLC's operating agreement. Many states require periodic reports, filing fees, a registered agent, and compliance with state tax obligations. Maintaining accurate financial records and keeping business and personal finances separate remain important.

What is a corporation?

A corporation is a legal entity separate from its owners, who are shareholders. It can issue stock, raise capital, and generally continues despite changes in ownership. A corporation's certificate or articles of incorporation authorize its stock; the number of authorized shares and the rights attached to them depend on its governing documents and state law.

A corporation is generally taxed as a C corporation unless it makes a valid S corporation election. A C corporation pays federal corporate income tax on its taxable income. If it distributes dividends, shareholders may also pay tax on those dividends, which is commonly described as double taxation.

If you're weighing alternative funding options for your business, your entity type can affect which options are practical.

How to form a corporation

To form a corporation, incorporators generally file articles or a certificate of incorporation with the appropriate state agency. Corporations typically adopt bylaws to govern the company's internal management.

Corporations commonly have shareholders, a board of directors, and officers. Specific governance requirements vary by state and by the corporation's governing documents.

Corporation compliance requirements

Corporations often have more formal governance and recordkeeping obligations than LLCs. Depending on state law and the corporation's governing documents, they may need to maintain corporate records, document board or shareholder actions, file periodic reports, and meet other requirements to remain in good standing. Written consents may sometimes be used instead of meetings.

Corporate tax status and purpose designations

The following terms describe different tax elections or mission-related designations. They are not three interchangeable forms of corporation:

C corporation

The default federal tax classification for a corporation. A C corporation generally pays corporate income tax, and shareholders may pay tax on dividends. C corporations can generally have an unlimited number of shareholders and can issue multiple classes of stock if authorized under applicable law and their governing documents.

S corporation

A federal tax election available to eligible domestic corporations and eligible LLCs. Income, losses, deductions, and credits generally pass through to shareholders. An S corporation may have no more than 100 shareholders and only one class of stock. Eligible shareholders generally include individuals, certain trusts, and estates; partnerships, corporations, and nonresident aliens generally are not eligible shareholders.

B Corp certification and benefit corporations

A Certified B Corporation is a voluntary certification issued by B Lab for businesses that meet its standards. A benefit corporation is a state-law corporate form available in some states. Either may have different tax treatment depending on its entity and tax elections.

Choosing an entity and tax status requires considering state law, ownership, funding, and tax advice.

LLC vs. corporation: Key differences

The core differences between an LLC and a corporation are their default tax treatment, management structure, ownership interests, and governance requirements.

Tax differences between LLCs and corporations

Tax treatment is one of the biggest differences between LLCs and corporations, but it is not determined by entity type alone. Federal elections, state rules, the owners' roles, and the business's income can all affect the result. Consult a qualified tax professional before choosing or changing a tax classification.

How LLCs are taxed

For federal income tax purposes, a domestic single-member LLC is generally treated as part of its owner unless it elects corporate treatment. A domestic LLC with two or more members is generally treated as a partnership unless it elects corporate treatment. Under these default classifications, the LLC's income generally passes through to its owners.

Self-employment tax may apply to some LLC income, particularly income from an active trade or business, but the treatment depends on the LLC's classification and each member's role. The combined Social Security and Medicare self-employment tax rate is generally 15.3%, though the Social Security portion is subject to an annual wage base and additional Medicare tax can apply above certain thresholds. It should not be assumed that 15.3% applies to every dollar of every LLC owner's income.

Business losses may also pass through to owners, but the ability to use them can be limited by basis, at-risk, passive-activity, and other tax rules.

How C corporations are taxed

A C corporation pays federal corporate income tax on taxable income. The federal corporate rate is 21% as of 2026. When a C corporation distributes dividends, shareholders may also owe tax on those dividends.

C corporations can retain earnings for business needs, but tax rules can limit the use of accumulated earnings to avoid shareholder-level tax. Both C corporations and pass-through businesses can generally deduct ordinary and necessary business expenses when the applicable tax rules are met. The treatment of deductions, benefits, compensation, and retained earnings can differ by entity and taxpayer.

S corporation election

Eligible LLCs and corporations can elect S corporation tax treatment by filing IRS Form 2553. With a valid election, income, losses, deductions, and credits generally pass through to shareholders' tax returns.

Shareholder-employees who perform services must generally receive reasonable compensation, which is subject to payroll taxes. Other distributions are not wages, but their tax treatment depends on the facts and applicable tax rules. An S corporation election can be useful in some circumstances, but it also adds payroll, filing, and eligibility requirements. It is not automatically a tax-saving choice.

When to choose an LLC vs. a corporation

Neither structure is universally better. An LLC may suit a business that values flexible management and default pass-through tax treatment. A corporation may suit a business that expects to issue stock, seek institutional financing, or use a conventional equity-compensation plan.

Consider these factors with legal and tax advisers:

• Business size and growth plans: An LLC can work well for businesses with a small ownership group, while a corporation may better match businesses planning a more conventional equity structure.
• Funding and investor needs: Many venture-capital investors prefer a Delaware C corporation, but investor requirements vary. Confirm expectations before choosing an entity solely for anticipated funding.
• Tax treatment: An LLC's default treatment, a C corporation's treatment, and an S corporation election can produce different results depending on the facts. Do not choose an entity based on a general tax-savings claim.
• Employee compensation plans: Corporations can use familiar stock-option and restricted-stock arrangements. LLCs can also grant equity interests, but the design and tax treatment can be more complex.
• Ownership and transfer rules: LLC operating agreements and corporate governing documents can define transfer restrictions, voting rights, and economic rights. Neither form guarantees unrestricted ownership transfers.

Choose an LLC if you:

• Want a flexible management structure
• Expect default pass-through tax treatment to fit your circumstances
• Have an ownership group that can document its rights in an operating agreement
• Do not expect a conventional venture-capital stock structure to be necessary soon

Consider a corporation if you:

• Expect to issue stock or pursue institutional financing that requires a corporate structure
• Want to use conventional stock-option or restricted-stock arrangements
• Want a board-led governance structure
• Are prepared to meet the applicable corporate governance and state-law requirements

You can convert an LLC to a corporation later through a statutory conversion, merger, or another available process. The process and its tax consequences depend on the state and the business's facts, so seek legal and tax advice before converting.

Pros and cons of an LLC vs. a corporation

The right structure depends on the business's ownership, funding plans, operational needs, and tax circumstances.

Advantages of an LLC

• Flexible management, including member-managed and manager-managed options
• Default pass-through federal income-tax treatment in many cases
• Operating agreement can tailor economic and governance rights
• Often fewer corporate-style formalities, depending on state law

Potential disadvantages of an LLC

• Equity interests may be less familiar to some institutional investors and employees
• Tax treatment of active members and distributions can be complex
• Transfer, voting, and continuation rules depend on state law and the operating agreement
• Some financing and equity-compensation structures may require more customization

Advantages of a corporation

• Can issue stock, including multiple classes when authorized
• Familiar governance and equity structure for many institutional investors
• Perpetual existence is generally available under corporate statutes
• Conventional stock-option and restricted-stock arrangements can be available

Potential disadvantages of a corporation

• C corporation dividends can result in corporate-level and shareholder-level tax
• Governance, reporting, and recordkeeping obligations can be more formal
• Formation and maintenance costs vary by state and may be higher in some circumstances
• Stock transfers can be subject to contractual restrictions and securities laws

Legal and administrative requirements

Forming an LLC or corporation requires state filings and ongoing compliance. Exact requirements vary by the formation state, the state where the business operates, and the entity's governing documents.

Formation documents

An LLC generally files articles of organization, or a similarly named document, with the state. Filing requirements vary and may include the business name, registered agent, and management information. An operating agreement commonly addresses ownership, profit and loss allocations, management roles, and decision-making rules.

A corporation generally files articles or a certificate of incorporation with the state. The formation document commonly addresses the corporation's name, registered agent, and authorized stock. Bylaws typically govern internal management, including director and officer roles and procedures.

Both entities generally need a registered agent in the state where they are formed. Filing fees, periodic reports, and franchise taxes vary significantly by state, so confirm current requirements with the relevant state filing office.

Ongoing compliance

Corporations often have more formal governance requirements than LLCs. Applicable state law and governing documents may require corporate records, documented director or shareholder actions, periodic reports, and franchise-tax filings. Failing to meet state requirements can lead to penalties or loss of good standing.

LLCs may also need to file annual or biennial reports, pay state fees or franchise taxes, maintain a registered agent, and keep accurate records. Requirements differ by state; do not assume that a state's LLC obligations are minimal.

If you form in Delaware but operate in another state, you may need to register as a foreign entity in the operating state and comply with both states' requirements. Your ERP or accounting software setup can also affect how smoothly you manage entity-level reporting.

How much it costs to form an LLC vs. a corporation

Formation and maintenance costs vary by state, the entity's complexity, and whether the business uses legal or tax advisers. An LLC is not always less expensive than a corporation.

State filing fees, annual or periodic reports, registered-agent fees, franchise taxes, and professional fees can apply to either structure. Corporations may involve more formal governance work, while an LLC with a customized operating agreement or complex ownership can also have substantial setup costs.

Confirm current requirements and fees with the relevant state agency. If you're also evaluating how to keep business and personal finances separate, avoiding using a personal credit card for business expenses is an important early step regardless of entity type.
