The History of CST

CST Tax Advisors was founded in 1992, by John Marcarian in Sydney when the business was known as Marcarian & Co.

John’s brother Matthew joined the firm in the year 2000 and together John and Matthew specialised in international taxation law focusing their Chartered Accountancy skills in this area.

From the early days John recognised that the private client tax market for Australian expatriates and Australian international businesses was a specialist market segment.

In 2004 John established the office of CST Tax Advisors in Singapore. Today CST Tax Advisors has offices in Sydney, Singapore, London and Los Angeles.


Tax advice provided the CST Way - the Australian way.

As John says

As John says

The beginning of the CST way was grounded in delivering quality services to the executive, private client or family business. I always believed that the relationship with the client was the foundation stone of the Firm and our obligation to maintain that relationship meant that we were not to be just about the chargeable hour and answering questions – but rather is a sense of obligation to go the extra mile to think about things that we ourselves would want done – if we were the client.

Our Key Value Proposition is to continue to provide expat individuals and international enterprises with integrated tax accounting and structuring advice for both their home markets and the international markets in which they operate. We do this by having empathy to their facts and circumstances and focusing on executing tax and business solutions.

We strongly believe that by focussing on clients living and working in abroad we can deliver on the above statement through our global brand and our united delivery platform.
