The main difference between a corporation and an LLC is how ownership, taxes, and governance are structured. Both are separate legal entities that shield your personal assets from business debts, but a corporation divides ownership into shares of stock, follows a formal three-tier governance hierarchy, and (as a standard C-corporation) pays its own income tax before shareholders are taxed again on dividends. An LLC uses membership interests, lets the owners design management and profit-sharing almost any way they want through a private operating agreement, and by default passes profits straight through to the owners’ personal returns without a separate entity-level tax.
Which one fits depends less on which sounds more “official” and more on how you plan to pay yourself, bring in co-owners, and raise money. The sections below walk through the differences that actually drive the decision.
Who Owns What
Ownership in a corporation is represented by shares of stock. Shareholders receive stock certificates or electronic records showing their interest, and corporations can issue different classes of stock, such as common and preferred, to give certain investors different voting rights or priority on dividends. By default, corporate shares are freely transferable. A shareholder can sell or gift shares without the other owners’ approval, which makes it easier for investors to come and go. Closely held corporations often add transfer restrictions through their bylaws or a shareholder agreement, for instance a right of first refusal for existing owners.
An LLC is owned by members who hold membership interests. Those interests carry both financial rights (a share of profits) and governance rights (a vote on decisions). Unlike corporate shares, membership interests usually cannot be transferred freely. Most operating agreements and state default rules require the existing members to consent before a new owner is admitted. A member can generally sell the right to receive profits, but the buyer does not become a voting member without approval from the others.
How Each Is Managed
Corporations use a three-tier structure. Shareholders elect the board of directors and vote on major transactions such as mergers. The board sets strategy and oversees direction. Officers like the CEO, treasurer, and secretary run day-to-day operations. The layered design creates checks and balances but also means an individual shareholder in a larger corporation has limited direct control. Directors owe fiduciary duties of care and loyalty to the company and its shareholders, and those duties are set by state law and cannot be eliminated entirely, though many states allow a corporation to limit personal liability for breaches of the duty of care.
An LLC picks between two management styles. In a member-managed LLC, all owners participate in daily decisions and each member can bind the company to contracts. In a manager-managed LLC, the members appoint one or more managers, who may or may not be owners, to run the business while the other members stay passive. The operating agreement controls the model and can divide authority almost any way the members agree on. Managers and managing members also owe fiduciary duties, but many states let the operating agreement modify or waive certain default duties, with limits such as not eliminating the duty of good faith. Corporate law does not offer the same room to customize.
How Each Is Taxed
Tax treatment is where the two entities differ most, and it is often the deciding factor.
C-Corporation
A standard corporation is a C-corporation. It files Form 1120 and pays a flat 21 percent federal income tax on its taxable income.1Office of the Law Revision Counsel. 26 U.S. Code 11 – Tax Imposed When it distributes after-tax profits as dividends, shareholders report those dividends on their personal returns and pay tax again.2Office of the Law Revision Counsel. 26 U.S. Code 301 – Distributions of Property That two-layer hit is commonly called double taxation.
LLC by Default
An LLC is not taxed as a separate entity by default. A single-member LLC is a “disregarded entity,” so the owner reports business income and expenses on Schedule C of their personal Form 1040.3Internal Revenue Service. 2025 Instructions for Schedule E (Form 1040) A multi-member LLC is treated as a partnership. The LLC files an informational Form 1065 and issues each member a Schedule K-1 showing their share of income, deductions, and credits, which the member reports on their personal return. Profits are taxed once, at the individual level. An LLC can also elect to be taxed as a corporation by filing Form 8832.4Internal Revenue Service. About Form 8832, Entity Classification Election
S-Corporation Election
Either a corporation or an LLC can elect S-corporation status by filing Form 2553.5Internal Revenue Service. Instructions for Form 2553 An S-corporation is a pass-through entity, so profits flow to the owners’ personal returns without a corporate-level tax. To qualify, the entity must:
- be organized in the United States;
- have no more than 100 shareholders;
- have only eligible shareholders, meaning individuals, certain trusts, or estates, and not partnerships, corporations, or nonresident aliens; and6Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined
- have only one class of stock, though voting differences alone do not count as a second class.
The election must be filed by the 15th day of the third month of the tax year (March 15 for calendar-year entities) or any time during the preceding tax year, and all shareholders must consent.7Office of the Law Revision Counsel. 26 U.S. Code 1362 – Election; Revocation; Termination
Self-Employment Tax
Self-employment tax is one of the biggest practical dividers. Active LLC members generally owe self-employment tax on their entire distributive share of business income. The combined 2026 rate is 15.3 percent (12.4 percent Social Security on income up to $184,500, plus 2.9 percent Medicare on all earnings).8Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet An additional 0.9 percent Medicare surtax applies to income above $200,000 for single filers or $250,000 for joint filers.
S-corporation shareholders who work in the business take a different route. They pay themselves a reasonable salary subject to employment taxes, and then take additional profits as distributions that are not subject to self-employment tax.9Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues The salary has to reflect fair compensation for the work actually done. Setting it artificially low to dodge employment taxes can trigger the IRS to reclassify distributions as wages. C-corporation shareholder-employees pay employment taxes only on their salary, and dividends are not subject to self-employment tax (though they still face the double-taxation dynamic).
QSBS: An Advantage Only C-Corporations Offer
C-corporations unlock a tax break LLCs cannot: the qualified small business stock (QSBS) exclusion under Section 1202. If you hold stock in a qualifying C-corporation for more than five years and then sell it, you can exclude up to 100 percent of the gain from federal income tax, up to the greater of $10 million or ten times your original investment.10Office of the Law Revision Counsel. 26 U.S. Code 1202 – Partial Exclusion for Gain From Certain Small Business Stock The company must be a C-corporation when the stock is issued and must meet asset-size and active-business tests. For founders and early investors in startups, this exclusion can be substantial, and it is simply unavailable through an LLC.
How Profits Get Paid Out
A corporation pays profits as dividends, and dividends must be proportional to share ownership. Own 10 percent of outstanding shares and you receive 10 percent of any declared dividend. The board decides when to declare one. Shifting the distribution formula requires creating different classes of stock with specific financial rights, which means amending the corporate charter.
LLCs can split profits and losses in ways that do not match ownership percentages. A member who contributes most of the labor can take a larger share of profits than a member who only put in startup cash. The IRS allows these special allocations as long as they have “substantial economic effect,” meaning the allocation produces real financial consequences for the members and is not just a tax-shifting device.11Office of the Law Revision Counsel. 26 U.S. Code 704 – Partner’s Distributive Share Treasury regulations spell out the detailed rules, including specific provisions the operating agreement must contain to support the allocation.12Internal Revenue Service, Treasury. 26 CFR 1.704-1 – Partner’s Distributive Share This flexibility is one of the main reasons LLCs are popular for joint ventures and real estate deals.
Ongoing Paperwork and Keeping Your Shield
Corporations have to follow more formalities to stay in good standing as a separate entity. Most states require an annual shareholder meeting, regular board meetings, and written minutes documenting decisions. The corporation adopts bylaws covering governance, officer elections, and meeting procedures, and keeps a corporate record book that includes stock ledgers and resolutions.
LLCs have fewer mandatory formalities. Most states do not require annual member meetings or formal minutes, and governance runs on the operating agreement rather than a statutory framework. Both entities generally have to file an annual report (sometimes called a periodic report or statement of information) with the state and pay a fee. Missing the filing can mean penalties, loss of good standing, or administrative dissolution.
Whichever structure you pick, the liability shield can be lost through a doctrine called “piercing the veil.” Courts look at whether owners treated the entity as truly separate: whether it was adequately funded at formation, whether business and personal finances stayed separate, whether required filings were kept up, and whether the entity was used to commit fraud or produce an unfair result. Corporations face more scrutiny on governance formalities, so skipping meetings, failing to issue stock, or neglecting minutes can count against the entity. LLCs can operate more informally, but keeping records and respecting the entity’s separateness still matters.
Raising Money and Giving Employees Equity
If you plan to raise outside capital, a C-corporation is usually the better fit. Venture capital firms and institutional investors tend to prefer it because it supports multiple rounds of equity financing through different stock classes, offers a clean path to an initial public offering, and qualifies for the QSBS exclusion. An LLC can raise capital by selling membership interests, but pass-through taxation creates complications for institutional investors, many of which are tax-exempt entities that face unrelated business taxable income from pass-through investments.
Employee equity works differently in each. Corporations grant stock options, a well-understood tool that fits with venture-backed compensation strategies. LLCs use profits interest units instead, giving the recipient a slice of future growth rather than existing value. Profits interests exist only in LLCs and partnerships and avoid some of the valuation complexity that applies to stock options. For companies planning to court outside investors or go public, stock options give corporations a recruiting edge.
Switching From One to the Other
An LLC that outgrows its structure can convert to a corporation. Many states allow a statutory conversion, where the LLC files a conversion document with the secretary of state and becomes a corporation without dissolving. In states that do not permit that, the same result is reached by merging the LLC into a newly formed corporation. After converting, the new corporation can file Form 2553 to elect S-corporation status if it qualifies.5Internal Revenue Service. Instructions for Form 2553 Conversion carries tax consequences and is worth planning with a tax professional before you file anything.
