What are the business types that are required to become company?

To become a "company," a business typically needs to be structured as a corporation, which means it has a separate legal identity from its owners, allowing for limited liability, and is usually formed by registering with the government as either a C corporation or an S corporation depending on the specific needs of the business; other business structures like a Limited Liability Company (LLC) can also be considered a company depending on the jurisdiction and how it's set up. 

Key business types that can be considered a company:

• Corporation:

The most common type of company with separate legal status from its owners, where ownership is represented by shares of stock. 

• Limited Liability Company (LLC):

Offers limited liability like a corporation while allowing for pass-through taxation similar to a sole proprietorship. 

• Partnership:

A business owned and operated by multiple individuals who share profits and liabilities. 

Other business structures that are not typically considered "companies" in the same way:

• Sole proprietorship:

A single-owner business is one in which the owner and business are legally the same entity. 

• Nonprofit organization:

A business focused on a public benefit rather than profit, often requiring additional registration and regulations.
