Australia — Business: Sole Proprietorship

A sole proprietorship in Australia is a simple business structure where an individual owns and operates the business, with the owner being personally responsible for its debts and obligations. While it's a common choice for small businesses, it's essential to understand the implications and requirements.

Key facts

  • The owner of a sole proprietorship is personally liable for the business's debts and obligations.
  • A sole proprietorship is not a separate entity from its owner, and the owner's personal and business assets are not separate.
  • Registration with the Australian Securities and Investments Commission (ASIC) is required for businesses with a name that is not the owner's surname and initials.

Steps

  1. Choose a Business Name — Ensure the name is unique and not already registered with ASIC. It's recommended to conduct a business name search on the ASIC website.
  2. Register with ASIC — Submit the required application and payment online through the ASIC website. The registration process typically takes 24-48 hours.
  3. Obtain an Australian Business Number (ABN) — Apply for an ABN on the Australian Taxation Office (ATO) website. This is a free service and typically takes 24-48 hours.
  4. Register for Goods and Services Tax (GST) if necessary — If the business's annual turnover is expected to exceed AUD 75,000, registration for GST is required. This can be done on the ATO website.
