In some of these roles he served as a virtual CFO across multiple industries, including retail fashion, financial services, cosmetics, real estate, and technology.


In 2016 Boon made the move overseas to head up to our Singapore office. His combined personal and professional background means he is ideally positioned to provide the specialist tax advice for both in-bound and out-bound taxation matters in Singapore. This includes expat employees and company founders entering Singapore.


Boon is a Chartered Accountant and a Chartered Tax Advisor. He obtained a Bachelor of Commerce from the University of New South Wales and a Master of Commerce from Macquarie University. In addition, Boon is a Member of the Sydney Chapter of the Society of Trust and Estate Practitioners.


As an expert in international taxation, Boon has appeared on radio segments to provide international tax advice to expats who live in Singapore. His prominence as a tax expert is expanded through featured articles in international tax journals. Boon is often a speaker at international tax focused events.


Boon loves playing basketball, reading a good book, and trying his eye at photography. Boon is married to Christina and has a son Jared.


It’s very important for me to understand my client’s personal circumstances before I provide advice. By building a personal relationship with my client, I can ensure that I provide a bespoke solution that meets their needs.
