When creating a business, one of the earliest and most fundamental decisions is settling on the appropriate Corporate Structure. Initially, the choice may seem rather abstract, but the consequences become very real when doing taxes, applying for loans, courting investors, or in a court of law. While changing the organization structure of a business is possible, it can be both costly and complicated. It is advisable to fully understand the various Corporate Structures that are available and the ways in which they will affect future business dealings before making a final decision. The primary business structures are LLC, corporation, partnership, sole proprietorship, and non-profit. Each provides an organization structure with benefits and drawbacks for any business model.
