LLC vs Corporation: Key Differences Explained

What is the difference between an LLC and a corporation? An LLC is a flexible legal entity with pass-through taxation by default, simpler paperwork, and member-based ownership. A corporation is a separate taxable entity with shareholders, a board of directors, formal bylaws and annual meetings, and either S-corp (pass-through) or C-corp (double-taxation) treatment. Most new small businesses pick an LLC for the balance of simplicity and protection; corporations are preferred by startups raising venture capital.

The LLC vs corporation decision shapes how you pay taxes, how much paperwork you owe each year, whether you can issue stock to employees, and how easily you can sell or wind up the business. This guide walks through the key differences across taxation, governance, ownership, paperwork, and the situations where each is the better fit.

What Is an LLC?

An LLC (Limited Liability Company) is a state-created legal entity that gives its owners (called “members”) personal liability protection while letting them choose how the business is taxed. By default, a single-member LLC is taxed as a sole proprietorship and a multi-member LLC is taxed as a partnership. The LLC itself does not file its own income tax return at the federal level unless it elects S-corp or C-corp treatment.

LLCs are the most popular new-business structure in the United States. They combine the legal protection of a corporation with the simplicity and tax flexibility of a partnership. See our full guide on how to start an LLC for the formation process.

What Is a Corporation?

A corporation is a separate legal and tax entity owned by shareholders. Corporations are governed by a board of directors elected by the shareholders, and the board appoints officers (CEO, CFO, Secretary) to run day-to-day operations. There are two main types for U.S. small businesses:

C corporation: The default. Taxed separately from its owners — pays corporate tax on profits, then shareholders pay personal tax on dividends (“double taxation”). Has no limit on shareholders or stock classes.
S corporation: A C-corp (or LLC) that elects S-corp tax treatment with the IRS. Income, losses, and credits flow through to shareholders’ personal returns, avoiding double taxation. Limited to 100 U.S.-resident shareholders and one stock class.

Taxation Compared

LLC taxation

By default, LLCs are pass-through entities. A single-member LLC files Schedule C with the owner’s personal return. A multi-member LLC files Form 1065 and issues K-1s to each member. The LLC itself does not pay federal income tax. Owners pay income tax plus self-employment tax (15.3%) on their share of the profit.

LLCs can elect S-corp treatment with Form 2553 to reduce self-employment tax on profits above a reasonable salary. They can also elect C-corp treatment with Form 8832, though this is rare unless raising VC money.

S-corp taxation

S-corps file Form 1120-S, an informational return. Profits pass through to shareholders via K-1s and are reported on their personal returns. The key benefit: shareholder-employees take a W-2 salary (subject to payroll tax) and receive remaining profits as distributions (not subject to self-employment tax). For an owner earning $150,000 net profit, the S-corp election can save $5,000–$15,000 per year in payroll taxes.

C-corp taxation

C-corps file Form 1120 and pay corporate income tax (21% federal, plus state). When profits are distributed to shareholders as dividends, shareholders pay personal tax on the dividends — the “double taxation” problem. However, C-corps allow lower owner salaries, retained earnings for reinvestment, multiple stock classes, and unlimited shareholders — features required for venture capital fundraising and going public.

Governance and Paperwork

LLC governance

An LLC is governed by an operating agreement — a private contract among members covering ownership, voting, profit distribution, and exit terms. There is no required annual meeting, no required board, and no required minutes (though documenting major decisions is good practice). Most LLCs file one annual report with the state.

Corporation governance

Corporations have more formal governance:

Bylaws (internal rules of the corporation)
Board of directors elected by shareholders
Officers (CEO, CFO, Secretary) appointed by the board
Annual shareholder meeting
Annual board meeting
Written minutes for every major decision
Stock ledger tracking ownership
Annual state filing plus, in some states, a separate franchise tax filing

Corporations that skip these formalities risk losing liability protection in the same way LLCs without operating agreements do.

Ownership and Stock

LLCs use “membership interests” — usually expressed as percentages in the operating agreement. There is no formal stock structure. Adding or removing members requires amending the operating agreement.

Corporations issue stock. The state filing authorizes a maximum number of shares, and the corporation can issue any portion of those to founders, employees, and investors. C-corps can issue multiple classes of stock (common, preferred, voting, non-voting) — essential for VC investment and employee stock options. S-corps are limited to one class of stock and 100 U.S.-resident shareholders, which makes them unsuitable for outside investment but fine for tax efficiency.

Liability Protection

Both LLCs and corporations provide personal liability protection — the entity is separate from the owners, and business debts and lawsuits stop at the entity level. The protection requires the same maintenance for both: separate bank account, no co-mingling of funds, separate accounting, signed governance documents (operating agreement or bylaws), and documented major decisions. Failing to follow these maintenance steps lets a court “pierce the corporate veil” and reach owners’ personal assets.

State Filing Fees and Annual Costs

State formation fees are similar for LLCs and corporations — typically $50–$500. Annual report fees and franchise taxes vary by state:

California: LLC has $800 minimum franchise tax; corporation also has $800 minimum.
Delaware: LLC annual fee $300; corporation franchise tax starts at $175.
Texas: No state income tax; both entities owe franchise tax on revenue over $1.23M.
Florida, Nevada, Wyoming: No state income tax; both have modest annual fees.

Tax preparation costs are also higher for corporations: a Form 1120 or 1120-S typically costs $1,500–$3,500 in CPA fees, vs $200–$600 for a Schedule C or $700–$2,500 for a Form 1065. See our state-by-state cost breakdown at how much it costs to start an LLC.

When to Choose an LLC

You want pass-through taxation and simple paperwork
You have one to a few owners and no plans to raise venture capital
You want maximum flexibility in how the business is managed and how profits are split
You may elect S-corp tax treatment later for tax savings, without changing the underlying entity
You operate a service business, e-commerce store, real estate holding, or other small-to-mid-size business

When to Choose a Corporation

You plan to raise venture capital — VCs strongly prefer Delaware C-corps
You want to issue stock options to employees
You need multiple classes of stock (preferred for investors, common for founders/employees)
You want to retain earnings inside the company at the corporate tax rate instead of passing profit through to owners’ personal returns
You are forming a non-profit (incorporates as a non-profit corporation)

Converting Between LLC and Corporation

You can convert from LLC to corporation or vice versa, but the process is costly and time-consuming. The common moves:

LLC to S-corp tax election: Easy — file Form 2553 with the IRS. The LLC stays an LLC at the state level.
LLC to C-corp: Two paths. Convert via state statute (where available) or form a new C-corp and merge the LLC into it. Often required when raising VC.
C-corp to LLC: Rare and complex; usually requires liquidating the corporation, which triggers significant taxes.
S-corp to LLC: Possible but requires re-formation and tax-event consequences.

The lesson: pick the right structure for the next 1–3 years, not for 20. An LLC with S-corp election covers most growth scenarios; switch to a C-corp only when actually raising VC.

Common Mistakes

Forming a Delaware C-corp by default. Unless you are raising VC, this wastes annual fees and adds complexity.
Skipping the S-corp election when profits justify it. Once net profit exceeds $80,000+, the election saves real money.
Treating the corporation as a piggy bank. Co-mingling personal and corporate funds breaks liability protection.
Not holding annual meetings. Corporations need documented annual board and shareholder meetings — skip them and you risk piercing the veil.
Forgetting to file annual reports. States dissolve LLCs and corporations that fail to file. Reinstatement costs hundreds.

Real-World Examples

Solo consultant earning $80k: LLC taxed as sole prop. Schedule C, no S-corp election yet.
Solo consultant earning $200k: LLC with S-corp election. W-2 salary plus distributions.
Two-partner agency: Multi-member LLC. Form 1065 with K-1s.
Tech startup raising seed funding: Delaware C-corp with preferred and common stock.
Large established company: C-corp, often headquartered in Delaware regardless of operations.
Non-profit: Non-profit corporation with 501(c)(3) IRS designation.

Where to File: Home State vs Delaware

Almost every founder should form in their home state — the state where the business actually operates. Forming in Delaware, Nevada, or Wyoming “for privacy” or “for the courts” rarely pays off for small businesses; you still owe taxes and registration in your home state as a foreign LLC, which doubles the fees. The exception: startups raising venture capital almost always form a Delaware C-corp because that is the structure investors expect. For broader federal guidance, see the IRS business structures page.

S-Corp vs C-Corp in More Detail

Both S-corps and C-corps are technically the same legal entity at the state level (a corporation). The difference is the tax election with the IRS. A new corporation is a C-corp by default. To become an S-corp, the corporation files Form 2553 within 2.5 months of the start of the tax year for which the election should apply. Key practical differences:

Ownership limits: S-corps cap out at 100 shareholders, all of whom must be U.S. citizens or residents (no LLCs, partnerships, or non-resident aliens). C-corps have no limits.
Stock classes: S-corps have only one class of stock (though voting and non-voting variations are allowed). C-corps can have multiple classes with different rights.
Tax treatment: S-corps avoid the double-taxation problem. C-corps pay corporate tax, then shareholders pay tax on dividends.
Retention of earnings: C-corps can hold profits inside the company at the corporate rate (21% federal). S-corps pass profits through to shareholders’ personal returns whether or not the money is actually distributed.
VC investment: VCs require C-corps. S-corp restrictions make it impossible to issue preferred stock or accept LLC investors.

How Liability Protection Differs in Practice

Both structures provide the same baseline protection on paper, but maintenance requirements differ. Corporations have a longer list of “formalities” — annual board meetings, annual shareholder meetings, written minutes, properly-issued stock certificates, signed bylaws, and stock ledger updates. Skipping these formalities is the most common reason courts pierce a corporate veil. LLCs have shorter formalities (operating agreement + annual report), but the same principle applies — treat the LLC as a separate entity, document major decisions in writing, and keep finances cleanly segregated.

Frequently Asked Questions

Is an LLC or a corporation better for taxes?

For most small businesses, the LLC’s pass-through taxation is simpler and cheaper. Once profits exceed roughly $80,000 per owner, an LLC with S-corp election saves payroll tax. C-corp taxation is rarely better for small businesses unless they retain large earnings or raise VC.

Can an LLC have shareholders?

No. LLCs have members, not shareholders. The ownership is expressed as membership interest (usually a percentage) in the operating agreement. Only corporations have shareholders and issue stock.

Which is easier to maintain — an LLC or a corporation?

LLC. Fewer required meetings, fewer required minutes, simpler tax filings, and a single operating agreement instead of bylaws plus board resolutions. The LLC is the default choice for founders who want legal protection without corporate-level paperwork.

Beneficial Ownership Reporting for Both Structures

As of 2024, most LLCs and corporations must file a Beneficial Ownership Information (BOI) report with the Financial Crimes Enforcement Network (FinCEN) within 90 days of formation. The report identifies anyone with 25%+ ownership or substantial control. The requirement applies equally to LLCs and to corporations — there is no avoiding it by picking one structure over the other. Penalties for late filing run up to $591 per day, so add the BOI report to your post-formation checklist regardless of entity type.
