Short answer
An LLC and a corporation differ in legal form, ownership terminology, and organizational documents—not simply in taxes. LLC owners are members; corporate owners are shareholders. An LLC can elect corporate treatment for federal income tax purposes, so a corporate tax label alone does not establish corporate legal form. 1 2

| Attribute | Limited liability company | Corporation |
|---|---|---|
| Owners called | Members | Shareholders |
| Formation document | Articles of organization | Articles of incorporation |
| Governance evidence supplied | No detailed LLC governance model | Bylaws define internal decision-making |
| Corporate federal tax classification | Available by election | SBA describes C corporation taxation |
These are separate legal-form and tax questions, not interchangeable labels. 1 2
What each thing is
An LLC is organized under state law as an LLC, with members generally protected from personal responsibility for its debts. A corporation is a separate legal entity that can earn profits and incur legal liability. Its shares represent ownership, and its incorporation documents outline the business. 1 2
Key differences
The supplied sources give corporations a more explicit governance framework: articles commonly identify directors and officers, while bylaws address decisions and responsibilities. SBA also describes more extensive corporate recordkeeping and reporting. The excerpts do not establish a comparable LLC management model, so they cannot support a universal claim that members always manage LLCs directly. 1
How to tell them apart
Start with the formation document: articles of organization filed as an LLC identify LLC formation; articles or a certificate of incorporation identify incorporation. Then examine governance documents separately. The limit: an IRS classification or election answers a federal tax question, not the same question as the formation record. 1 2
Where they overlap
Both structures can have one or more owners and provide protection against personal liability. That shared protection is not absolute: SBA explicitly notes limits, and the IRS describes LLC members as generally—not invariably—free from personal liability for entity debts. Limited liability therefore does not distinguish the two by itself. 1 2
Edge cases
A corporate tax election is the central boundary case: the IRS expressly allows an LLC to be classified as a corporation, including an eligible S corporation. Conversely, close corporations can shed many typical corporate formalities. Neither tax treatment nor the apparent degree of formality is a reliable standalone legal-form test. 1 2
Why the distinction exists
The distinction separates organizational identity from tax administration. Formation documents establish the business’s legal framework; federal classification determines how an LLC is treated for income tax purposes. Corporate governance documents address a different issue again: how decisions are made and how officer and shareholder responsibilities are allocated. 1 2
Common misconceptions
“Corporation” does not automatically mean that every ownership change interrupts the business: SBA describes corporate continuity after shareholders leave or sell shares. Nor should that continuity be assumed for every LLC; SBA notes that some states may impose consequences when members join or leave. State-specific details remain essential. 1
Examples
Hypothetical case one: a business files articles of organization as an LLC, then elects corporate federal income tax classification. Its tax label does not replace its LLC formation identity. Hypothetical case two: a shareholder sells shares in an incorporated business. That ownership change can occur without disrupting the corporation’s continued existence. 1 2
