Registration Corporation

Firm that meets certain legal requirements to be recognized as having a legal existence, as an entity separate and distinct from its owners. Corporations are owned by their stockholders (shareholders) who share in profits and losses generated through the firm's operations, and have three distinct characteristics (1) Legal existence: a firm can (like a person) buy, sell, own, enter into a contract, and sue other persons and firms, and be sued by them. It can do good and be rewarded, and can commit offence and be punished. (2) Limited liability: a firm and its owners are limited in their liability to the creditors and other obligors only up to the resources of the firm, unless the owners give personal-guaranties. (3) Continuity of existence: a firm can live beyond the life spans and capacity of its owners, because its ownership can be transferred through a sale or gift of shares.

LLC

A limited liability company (LLC) is a corporate structure whereby the members of the company cannot be held personally liable for the company's debts or liabilities. Limited liability companies are essentially hybrid entities that combine the characteristics of a corporation and a partnership or sole proprietorship. While the limited liability feature is similar to that of a corporation, the availability of flow-through taxation to the members of an LLC is a feature of partnerships.

Although LLCs have some attractive features, they also have a number of disadvantages, especially in relation to the structure of a corporation. A LLC has to be dissolved upon the death or bankruptcy of a member, unlike a corporation, which can exist in perpetuity. Also, a LLC may not be a suitable option when the objective of the founder is to eventually become a publicly listed company.

Sole Proprietor

A sole proprietorship, also known as a sole trader or a proprietorship, is an unincorporated business with a single owner who pays personal income tax on profits earned from the business. With little government regulation, a sole proprietorship is the simplest business to set up or take apart, making sole proprietorships popular among individual self-contractors, consultants or small business owners. Many sole proprietors do business under their own names because creating a separate business or trade name isn't necessary. 

A sole proprietorship has no separation between the business entity and its owner. It is therefore different from corporations and limited partnerships, in that no separate legal entity is created. Consequently, the business owner of a sole proprietorship is not safe from liabilities incurred by the entity. For example, the debts of the sole proprietorship are also the debts of the owner. However, all profits flow directly to the owner of a sole proprietorship.
