An LLC and a corporation both protect your personal assets from business debts, but they differ sharply in how they are taxed, how they are run, and how much paperwork they demand. The clearest practical difference in an LLC vs. corporation comparison is tax: a C corporation pays a flat 21% federal tax on its profits before anything reaches the owners, while an LLC’s profits skip the entity-level tax and land directly on the members’ personal returns.1Office of the Law Revision Counsel. 26 U.S. Code 11 – Tax Imposed Corporations also carry heavier governance obligations, while LLCs give you room to tailor profit splits and management to the deal the owners actually want. Which one fits depends on how you plan to raise money, divide profits, and operate day to day.
How Taxes Work
Taxes are where most owners feel the difference first, and the two entities start from opposite defaults.
C Corporations Pay First, Shareholders Pay Second
A standard C corporation pays federal income tax on its profits at a flat 21%.1Office of the Law Revision Counsel. 26 U.S. Code 11 – Tax Imposed When the company then distributes after-tax profits as dividends, shareholders owe tax again on their personal returns. That is the “double taxation” people warn about, but it is less punishing than it sounds: qualified dividends are taxed at long-term capital gains rates of 0%, 15%, or 20%, not at ordinary income rates. A shareholder in the 15% qualified dividend bracket pays an effective combined rate around 33% on distributed profits.
The structure has an upside if you plan to reinvest. A C corporation can retain earnings inside the company and plow them back into the business without triggering any shareholder-level tax. For a growth-focused business, the 21% flat rate can be lower than the top individual rates a pass-through owner would face.
LLCs Pass Profits Through to the Owners
An LLC does not pay federal income tax as an entity. Profits and losses pass through to the members’ personal returns. A single-member LLC is treated as a disregarded entity, and the owner reports income on Schedule C. A multi-member LLC is treated as a partnership, filing an informational Form 1065 and issuing each member a Schedule K-1.2Internal Revenue Service. LLC Filing as a Corporation or Partnership
Pass-through taxation sidesteps the double tax entirely. Every dollar of profit is taxed once, at the member’s individual rate. There is a trap, though. Members owe tax on their allocated share of profits whether or not the LLC actually distributes cash. If the business earns $200,000 and reinvests all of it, each member still owes tax on their share. First-time LLC owners sometimes call that “phantom income” when the bill arrives.
The S-Corp Election Both Entities Can Make
Neither entity is permanently locked into its default tax treatment. Both LLCs and C corporations can elect S-corporation status by filing Form 2553 with the IRS. The election must be filed no later than two months and 15 days after the start of the tax year you want it to take effect, or at any time during the prior tax year.3Internal Revenue Service. S Corporations
An S corporation is a pass-through entity, so profits flow to the owners’ returns and skip entity-level tax. The payoff over a default LLC involves self-employment taxes. LLC members typically owe self-employment tax of 15.3% (covering both halves of Social Security and Medicare) on their entire share of the business’s net income.4Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) S-corporation shareholder-employees pay employment taxes only on the salary the company pays them. Distributions above that salary are subject to income tax but not Social Security or Medicare.
There is a condition. The IRS requires shareholder-employees to pay themselves a “reasonable” salary before taking distributions.5Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers Setting a $20,000 salary and taking $180,000 as distributions will not survive an audit; compensation has to reflect what someone in a comparable role would earn. Even a defensible split can save thousands in employment taxes each year for a profitable business.
Not every business qualifies. The company must be domestic, with no more than 100 shareholders, only one class of stock, and shareholders limited to U.S. citizens or residents and certain trusts and estates.6Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined An LLC that cannot meet those limits can instead file Form 8832 to be classified as a C corporation, which brings back double taxation.2Internal Revenue Service. LLC Filing as a Corporation or Partnership
The 15.3% self-employment rate applies to net earnings up to the Social Security wage base of $184,500 in 2026, and 2.9% applies above that.7Social Security Administration. Contribution and Benefit Base An additional 0.9% Medicare surtax hits earnings above $200,000 for single filers.4Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) Once net income consistently exceeds roughly $50,000 to $60,000, the S-corp election is worth running past a tax professional.
The Qualified Business Income Deduction
Pass-through business owners, whether they operate as LLCs, S corporations, or sole proprietors, may be eligible for a 20% deduction on qualified business income under Section 199A. The deduction was originally set to expire after 2025, but the One Big Beautiful Bill Act, signed into law on July 4, 2025, made it permanent.8Internal Revenue Service. One, Big, Beautiful Bill Provisions
In practice, the deduction lowers the effective top marginal rate on pass-through income from 37% to about 29.6%. C corporations do not qualify because they already pay the flat 21% at the entity level. Income limits and restrictions for certain service-based businesses, including law, medicine, and consulting, can reduce or eliminate the deduction at higher income levels, so it is not a blanket benefit.
Who Owns It and How Ownership Moves
LLC owners are called members. Their stake is usually expressed as a percentage of membership interest or as units, and the operating agreement can split profits in whatever ratio the members negotiate. Two members who each own 50% can agree that one receives 70% of profits because that person contributes more labor. That kind of customized allocation is the LLC’s signature advantage.
Corporation owners are called shareholders and hold shares of stock. Most corporations issue common stock, which carries voting rights, and may also issue preferred stock, which typically has priority for dividends or for asset distribution if the company dissolves. Shares follow standardized rules, which makes them easy to transfer, sell to outside investors, or eventually list on a public exchange.
Transferring an LLC membership interest is more complicated. Under most state default rules, a member can transfer the economic rights to their interest, such as the right to receive distributions, without approval from the other members. Transferring voting and management rights almost always requires unanimous consent unless the operating agreement says otherwise. Corporate shares can generally be sold or gifted freely. If you plan to bring in investors or eventually sell your stake, that difference matters.
How Each One Is Managed
Corporations follow a layered structure that state law requires. Shareholders elect a board of directors to set strategy. The board appoints officers, typically a president, secretary, and treasurer, to handle daily operations. The bylaws spell out voting procedures, meeting requirements, and how much authority each officer carries.
LLCs offer two paths. In a member-managed LLC, the owners run the business themselves and share decision-making. In a manager-managed LLC, the members appoint one or more managers (who may or may not be members) to handle operations while the remaining members stay passive. The operating agreement governs who votes, how disputes get resolved, and which decisions need a majority versus unanimous approval. Skip the operating agreement and state default rules fill the gaps, and those defaults rarely match what the members actually intended.
Both entity types must designate a registered agent in every state where they operate. The registered agent is a person or service with a physical street address in that state who accepts legal documents and official notices during normal business hours. A P.O. box does not qualify. Letting this requirement lapse risks missing a lawsuit filing or losing good standing with the state.
Forming the Entity and What It Costs
Both entity types are created by filing a document with the Secretary of State (or equivalent office). For an LLC, you file Articles of Organization, called a Certificate of Formation in some states. For a corporation, you file Articles of Incorporation, which must additionally specify the number and classes of shares the company is authorized to issue.
Filing fees vary by state. LLC formation fees range from about $35 to $500, with most states charging $100 to $150. Corporation fees fall in a similar range. These are one-time costs; the ongoing annual fees are separate.
After the state approves your filing, both LLCs and corporations need a federal Employer Identification Number from the IRS. The application is free and takes minutes online. You need the EIN before you can open a business bank account, hire employees, or file tax returns for the entity.9Internal Revenue Service. Employer Identification Number One sequencing detail: register the entity with the state first, then apply for the EIN.
Ongoing Compliance and Formalities
This is where the two entities diverge most on day-to-day burden.
Corporate Formalities
Corporations must hold annual meetings of both the board of directors and the shareholders. Minutes must be recorded and kept in the corporate records. The company must maintain a stock ledger tracking all share issuances and transfers, and major decisions need to be documented through formal board resolutions. Skipping these formalities is one of the primary factors courts look at when deciding whether to pierce the corporate veil and hold owners personally liable.
LLC Formalities
LLCs face far fewer mandatory requirements. Most states require an annual or biennial report filed with the Secretary of State, along with a filing fee. Fees range from $0 in states like Arizona and Missouri, which do not require a report, to over $800 in California once franchise taxes are included. The typical fee across most states falls between $50 and $200. LLCs have no statutory obligation to hold formal meetings or record minutes, though doing so is still a smart practice for protecting the liability shield.
Operating Across State Lines
If your LLC or corporation does business in a state other than where it was formed, you generally need to foreign qualify by filing for a Certificate of Authority in each additional state. That requires appointing a registered agent in that state, obtaining a Certificate of Good Standing from your home state, and paying another filing fee. Failing to qualify can bring penalties and the loss of your right to bring lawsuits in that state’s courts.
Keeping Your Liability Shield Intact
The point of forming an LLC or corporation is to keep business liabilities away from your personal bank account, your house, and your other assets. That protection is not automatic. It survives only as long as you treat the business as genuinely separate from yourself. Courts pierce the veil and impose personal liability when they find the entity was really the owner’s alter ego.
The behaviors that get owners in trouble are consistent across cases:
- Commingling funds: paying personal expenses from the business account, depositing business checks into your personal account, or failing to maintain separate bank accounts at all.
- Ignoring formalities: never adopting bylaws or an operating agreement, never holding meetings or documenting decisions, and interchanging the owner’s name with the business name on contracts and invoices.
- Undercapitalization: starting the business without enough capital to cover its foreseeable obligations. A company that never had the money to operate independently looks like a shell, not a real entity.
- Fraud or misrepresentation: making deals knowing the business cannot pay, or altering financial records to disguise the company’s actual condition.
LLCs are slightly more vulnerable here than corporations, because the lighter compliance load means owners are more likely to skip the protective habits — separate accounts, documented decisions, adequate insurance — that keep the veil intact. Maintaining clear financial boundaries between yourself and the entity costs almost nothing in time or money. Losing that liability protection can cost everything you own.
