LLC vs Corporation: Taxes, Liability, Formalities (2026)

Quick answer: An LLC (limited liability company) and a corporation both shield owners from business debts. An LLC is taxed as a pass-through by default and has few formalities. A corporation, usually a C corporation, pays its own 21% federal income tax, has shareholders and a board, and must follow stricter rules, but suits outside investment.

The LLC vs corporation decision shapes how you pay tax, how you raise money, and how much paperwork you handle every year. Most freelancers and small service businesses choose an LLC, while startups seeking venture capital usually form a C corporation. This guide explains the difference, compares taxes with a worked example, and covers formalities, costs and common mistakes. It is general information, not legal or tax advice.

What is the difference between an LLC and a corporation?

Both are legal entities created under state law by filing with the secretary of state. Both separate the business from its owners. The differences are in ownership structure, management and default tax treatment.

• LLC: Owned by members. Run by members or managers under an operating agreement. By default, a single-member LLC is taxed as a sole proprietorship (a disregarded entity) and a multi-member LLC as a partnership.
• Corporation: Owned by shareholders who hold stock. Run by a board of directors that appoints officers, under bylaws. By default it is a C corporation for federal tax purposes. It can elect S corporation status if it qualifies.

If you are still deciding whether you need an entity at all, compare an LLC with a sole proprietorship first.

How is an LLC taxed compared with a corporation?

LLC taxation

An LLC's profit flows through to the owners, who pay income tax at their personal rates whether or not they withdraw the money. Active owners also pay self-employment tax of 15.3% on net earnings up to the Social Security wage base (2.9% Medicare above it). Many owners can also claim the qualified business income (QBI) deduction of up to 20%, which the One Big Beautiful Bill Act made permanent. Our guide to the LLC tax rate walks through the numbers, and how to file taxes as an LLC covers the forms.

C corporation taxation

A C corporation pays a flat 21% federal income tax on its profit. When it pays dividends, shareholders pay tax on them again, usually at qualified dividend rates of 0%, 15% or 20%, plus the 3.8% net investment income tax for higher earners. Owners who work in the business are employees and receive wages subject to payroll taxes, which the corporation deducts.

The S corporation option

An S corporation is a tax status, not a separate entity type. Both LLCs and corporations can elect it with IRS Form 2553 if they meet the rules (for example, no more than 100 shareholders and one class of stock). Profits pass through like an LLC, but owners take a reasonable salary and can avoid self-employment tax on the remaining distributions. See our S corp vs LLC comparison and the Form 2553 guide.

Worked example: $150,000 of profit

Consider a single owner whose business makes $150,000 of profit before owner pay. The figures below are simplified to show the structure only; they ignore state tax, the QBI deduction, retirement contributions and personal deductions, and use rounded federal rates.

Step	LLC (default pass-through)	C corporation, pays $80,000 salary and distributes the rest
Owner wages	None (owner draws)	$80,000, deductible to the corporation
Payroll or self-employment tax	About $21,200 self-employment tax on $150,000 x 92.35%	$12,240 total payroll tax (7.65% employer + 7.65% employee)
Corporate profit after wages and employer payroll tax	Not applicable	$150,000 - $80,000 - $6,120 = $63,880
Corporate tax at 21%	None	About $13,415
Dividend paid to owner	Not applicable	About $50,465, taxed at 15% = about $7,570
Owner's personal income subject to ordinary rates	About $139,400 (profit minus half of SE tax)	$80,000 wages

In this simplified case, the C corporation has lower ordinary income for the owner but adds corporate tax and dividend tax. Whether total tax is higher or lower depends on the owner's bracket, state taxes and how much is retained in the company. For many small businesses with this profit level, an LLC taxed as an S corporation ends up most efficient, which is why a CPA should model your actual numbers.

What formalities does each require?

LLC

• File articles of organization and appoint a registered agent
• Adopt an LLC operating agreement (required in some states, wise in all)
• Get an EIN if you have employees, multiple members or a tax election. Our guide to getting an EIN explains the free IRS process
• File the state annual report and pay any fees or franchise taxes

Corporation

• File articles of incorporation, adopt bylaws and issue shares
• Elect a board of directors and appoint officers
• Hold an organizational meeting and annual board and shareholder meetings, with minutes
• Keep a stock ledger and file annual reports
• Run payroll for owner-employees

Both should keep a separate business bank account, sign contracts and invoices in the entity's name and avoid mixing personal spending. Our guide to invoicing as an LLC shows how to present your legal name and tax details on invoices.

What does limited liability actually protect?

Limited liability is the main reason to form either entity, but it is narrower than many owners assume.

Situation	Usually protected?	Notes
Business cannot pay a supplier invoice	Yes	The entity owes the debt, not you, unless you signed a personal guarantee
Customer sues the business over a product	Yes, for your personal assets	Business assets are still at risk; insurance matters
You personally make a negligent mistake	No	You remain liable for your own acts; professional liability insurance helps
Bank loan or lease with a personal guarantee	No	Most small business lenders require one
Unpaid payroll taxes withheld from employees	No	The IRS can assess the trust fund recovery penalty against responsible people
Owner mixes personal and business funds	At risk	Courts may pierce the veil

In this respect there is little difference between an LLC and a corporation. Both need good habits: separate bank accounts, signed agreements in the entity's name, adequate insurance and up-to-date state filings. Our guide on how to start an LLC covers these setup steps.

How should each entity appear on invoices and contracts?

Clients, banks and the IRS look at your legal name. On every invoice, show the full registered name, including the suffix, and the tax ID where needed. A typical invoice header:

Field	LLC example	Corporation example
Legal name	Brightline Design LLC	Brightline Design, Inc.
Trade name (if any)	DBA Brightline Studio	DBA Brightline Studio
Address	Registered business address	Registered business address
Tax ID	EIN (or owner's SSN for a single-member LLC without employees, though an EIN is better on invoices)	EIN
Signature on contracts	Jane Doe, Member, Brightline Design LLC	Jane Doe, President, Brightline Design, Inc.

Signing with your title and the entity name shows you act for the business, not yourself. Corporations generally do not receive Form 1099-NEC from clients, while LLCs usually do unless taxed as a corporation; our guide to whether an LLC gets a 1099 explains the rule.

How much does it cost to form and run each?

State fees are set by each secretary of state and change from time to time, so treat these as examples and check your state's website. Two well-known cases show how much ongoing costs can vary:

State example	LLC ongoing cost	Corporation ongoing cost
California	$800 minimum annual franchise tax, plus a gross receipts fee above certain levels and a statement of information	$800 minimum franchise tax, or 8.84% of net income if higher, plus a statement of information
Delaware	$300 annual tax	Franchise tax based on shares or assets, plus an annual report fee

Beyond state fees, budget for a registered agent if you use a service, bookkeeping, and tax preparation. A corporation's Form 1120 or an S corporation's Form 1120-S usually costs more to prepare than a single-member LLC's Schedule C, and running payroll adds a monthly payroll service fee. These ongoing costs often matter more than the one-time filing fee.

Invoicing costs nothing extra under either structure: you can bill in the entity's name with a free invoice generator from day one.

How to choose: a step-by-step decision checklist

1. Do you plan to raise venture capital or issue stock options? If yes, a C corporation (often in Delaware) is the usual choice.
2. Will you reinvest most profits rather than pay them out? The 21% corporate rate can help, but compare with your personal bracket.
3. Is your profit high enough for payroll to make sense? If self-employment tax is large, look at an LLC with S corporation election.
4. How much admin can you handle? LLCs need less paperwork.
5. What does your state charge? Compare formation fees, annual reports and franchise or minimum taxes.
6. Talk to a CPA or attorney before filing, especially with partners or investors.

Common mistakes when choosing an entity

• Choosing a corporation just for the 21% rate. Dividend tax and payroll costs can erase the benefit.
• Thinking an LLC lowers taxes on its own. A default LLC is taxed the same as a sole proprietor or partnership.
• Skipping the operating agreement or bylaws. Disputes between owners get expensive without one.
• Mixing personal and business funds. It weakens liability protection and complicates bookkeeping.
• Invoicing in your personal name. Clients should contract with the entity, not you.
• Missing state annual reports. Your entity can fall out of good standing or be dissolved.

One more practical point: banks, payment processors and many larger clients will ask for your formation documents, EIN confirmation letter and beneficial owner details when you open accounts or onboard as a vendor. Keep digital copies of your articles, operating agreement or bylaws, and IRS letters in one folder so you can answer these requests quickly, whichever entity you choose.

LLC vs corporation: the bottom line

For most freelancers and small owner-run businesses, the LLC vs corporation choice favors an LLC: liability protection, pass-through taxes, optional S corporation election and light paperwork. Choose a C corporation if you plan to raise outside investment, issue equity widely or retain substantial profits. Once your entity is set up, bill clients in its legal name.
