The business entity definition is an organization founded by one or more natural persons to facilitate specific business activities or to allow its owners to engage in a trade.
What Is a Business Entity?
Business entities are organizations formed by one or more persons. Since they are formed at the state level, they must comply with state laws. In most states, a business owner is required to file documents with a particular state agency, like the office of the Secretary of State, in order to legally set up their business.
Types of business entities include:
- Sole Proprietorships
- Partnerships
- Corporations
- Limited liability companies (LLCs)
- Limited liability partnerships
A sole proprietorship is the easiest type of business entity to set up because it doesn't require any legal forms. However, since there is one owner, that person is legally liable for any damages related to their business activity.
A partnership is a business entity that involves two or more individuals. Like a sole proprietorship, a partnership can be formed without paperwork.
Of course, a corporation is the most popular type of business entity. That's because its owners are protected by limited liability.
Types of Business Entities Explained
In addition to the commonly known categories, here are details about how each business entity functions:
- Sole Proprietorship: Owned by one individual, easy to form, but offers no liability shield.
- Partnerships: Can be general or limited; in general partnerships, all partners share liability, while limited partnerships allow for liability limits for some partners.
- Limited Liability Company (LLC): Combines partnership flexibility with corporate liability protection. Often chosen by small and medium businesses.
- Corporation: A separate legal entity with strong liability protection and perpetual existence. Subcategories include C-Corps (subject to double taxation) and S-Corps (allowing pass-through taxation with shareholder restrictions).
- Limited Liability Partnership (LLP): Protects individual partners from certain liabilities of other partners. Often used by professional service firms.
Key Factors in Choosing a Business Entity
When deciding how to structure a business, it is important to weigh factors such as liability, taxation, governance, and long-term goals. For example:
- Liability Protection: Corporations and LLCs provide personal asset protection, while sole proprietorships and partnerships expose owners to unlimited liability.
- Taxation: Sole proprietorships and partnerships have pass-through taxation, while corporations are subject to corporate tax (C-Corps) or hybrid taxation (S-Corps).
- Ease of Setup: Sole proprietorships require minimal paperwork, while corporations and LLCs require state filings, bylaws or operating agreements, and compliance obligations.
- Funding Options: Corporations often attract investors more easily due to stock issuance, while partnerships and sole proprietorships rely heavily on personal or partner resources.
What Are 'Disregarded' Business Entities?
Business entities are often subject to taxation, so the business owners must file a tax return for those businesses.
Often, the owner of a single-member limited liability company or a sole proprietorship only needs to file a single tax return. In this case, the business entity and the count as one and the same. Also, the IRS "disregards" those business entities because the owner only needs to report their personal income and deductions. When the business owner files their taxes, they will report their business expenses and income on a Schedule C form along with their personal Form 1040.
Alternatively, a one-member business could be treated as a separate entity. If the owner of the business chooses to go that route, they will have to fill out a Form 8832 to declare an Entity Classification Election and file the form with the IRS. Unless the owner of the sole proprietorship or single-person LLC files the Form 8832 for their business, that business entity will fall into the default classification of a disregarded entity.
What Is the Business Entity Concept for Accounting?
According to the business entity concept — also known as the separate entity or economic entity concept — financial transactions that happen in a business should be kept separate from those of the business's owners or any other business. That means when money moves in or out of that business, those transactions should be kept in their own set of accounting records. Business owners can apply the business entity concept to any type of business to make accounting much easier.
For example, if you loan money to your own company, that counts as one of your business's liabilities because you would need to pay yourself back. Also, if you have a business credit card, make sure you don't use a personal credit card for your business. If you use your personal credit card for your business, that will be counted as a loan or additional capital.
Principles Underlying the Business Entity Concept
The business entity concept, sometimes called the economic entity assumption, is rooted in the idea that each business should be treated as separate from its owners. Key principles include:
- Clarity in Records: Ensures that personal expenses and business expenses do not overlap.
- Legal Accountability: Supports enforcement of contracts, taxes, and compliance by separating ownership from the entity.
- Comparability: Allows stakeholders to assess one business independently from another.
- Auditing Ease: Simplifies external reviews and regulatory checks.
- Ethical Financial Reporting: Helps prevent misrepresentation or fraud by requiring consistent record-keeping.
Why Is the Business Entity Concept of Accounting So Important?
There are six reasons why the business entity concept is the preferred type of accounting setup for business organizations. Consider:
- When the accounting records of a particular business are kept separate, business owners can compare that business's profitability, et al to other businesses they own. If the business entity's accounting records include financial information about the business's owners or other businesses, it will be hard to keep track of the finances for each business in question.
- Business owners can measure one business's finances against the finances of any other business during a certain time period.
- Business owners who use this concept can compare their business' finances to other businesses in their industry.
- It will be much simpler to keep track of a business's records and audit them.
- Each business entity a person owns will be taxed separately.
- If the business needs to be liquidated, having separate financial records for the business allows its various owners to determine how they will be compensated.
Real-World Examples of the Business Entity Concept
- Example 1: If an owner pays personal rent with business funds, it must be recorded as a draw or owner’s distribution, not as a business expense.
- Example 2: A loan from the owner to the business should be recorded as a liability owed by the company, reinforcing the distinction between owner and entity.
- Example 3: Multinational corporations operating subsidiaries in different countries must treat each subsidiary as a separate entity for both accounting and legal purposes.
