What business structure should I use? – StartupSmart

Choose the structure that will best suit the needs of your business. Your decision will determine how you have to register your business and which laws you have to observe. It is vital that you understand the legal requirements of your business setup and seek legal advice in making a decision on your business structure.


There are four main business structures that are commonly used in small businesses. In increasing level of legal complexity, these are:


  • Sole trader: an individual trading on their own.
  • Partnership: an association of people or entities carrying on a business together, but not as a company.
  • Trust: an entity that holds property or income for the benefit of others.
  • Company: a legal entity separate from its shareholders.
  • Each has advantages and disadvantages.
