The four main types of business entities are…

1. Sole Proprietorship – A sole proprietorship is the simplest form of business entity and is owned and operated by one individual. The owner has full control over the business and is personally liable for its debts and obligations. Sole proprietorships are easy to establish and require minimal formalities, but they offer no liability protection for the owner.

2. Partnership – A partnership is a business entity owned and operated by two or more individuals who share ownership, management, profits, and liabilities. There are several types of partnerships, including general partnerships, limited partnerships, and limited liability partnerships (LLPs). In a general partnership, all partners are personally liable for the partnership’s debts and obligations. Limited partnerships include both general partners (with unlimited liability) and limited partners (with liability limited to their investment). LLPs provide liability protection to all partners.

3. Corporation – A corporation is a legal entity that is separate and distinct from its owners (shareholders). Corporations can enter contracts, incur debts, and engage in business activities. Shareholders have limited liability, meaning their assets are generally protected from the corporation’s debts and liabilities. Corporations have a formal management structure, including a board of directors, officers, and shareholders. There are two main types of corporations, C corporations and S corporations, which differ in terms of taxation and ownership restrictions.

4. Limited Liability Company (LLC) – A limited liability company (LLC) is a hybrid business entity that combines features of corporations and partnerships. Like corporations, LLCs provide limited liability protection to their owners (members), meaning their assets are generally shielded from the company’s debts and liabilities. Yet, like partnerships, LLCs offer flexibility in management structure and taxation. LLCs can be managed by their members or appointed managers, and they are typically taxed as pass-through entities, with profits and losses passing through to the members’ tax returns.

These four main types of business entities offer different advantages, disadvantages, and legal considerations, and the choice of entity depends on factors such as liability protection, taxation, management structure, and business goals.
