When you first start a business, you'll need to decide on its structure. Your business structure identifies how you operate as a trading business. It'll affect things like:

  • who can make important decisions
  • tax advantages and disadvantages
  • how profits and losses are shared
  • legal obligations and costs.

You can change your business structure as your business grows or situation changes.

Popular business structures

For new businesses, the 3 most popular business structures are:

  • sole trader – this is a simple business structure that gives the owner all the decision-making power.  Business losses can be written off your PAYG tax from another job. You can also hire staff if you want to.
  • partnership – this is when between 2 and 20 people go into business together. Partnerships can be either general or limited, depending on the liability of the partners.
  • company – usually, a company has members (shareholders) who own the company and directors who run it. Or an independent contractor can also set up a 'one-person company' with a sole director and member. Companies can also be publicly listed, which means the public can buy shares to invest in the company.

Once you understand the difference between these structures, you can choose the best one for your business.
