hi Kim Nguyen, aged 39 years, visited your practice to discuss GST-related issues and a possible change in her business structure. She is currently working as a sole trader and often has to treat various customers to lunches to keep the sales contracts. The lunches are all business related. In addition, Kim uses her private car to drive to the lunch venues. Kim wishes to claim GST credits on the business lunches and car expenses. Kim earns $150,000 (net of deductions) from her sole trading business. She wishes to change her business structure from sole trader to another structure commencing on the 1 July 2022.

Annabelle Nguyen: Kims 20-year-old daughter. She is a full-time university student, who currently has no income. Clare Nguyen: Kims 16-year-old daughter. She is a high school student. Kim is considering one of the following options: A partnership with Ahn, Duc, Annabelle and Clare Nguyen in an equal profit-sharing ratio of 20% each.
