About Us

Our journey began in 1992 when our Founder, John Marcarian, founded his own practice in Sydney.

Focusing on private clients and their globally mobile aspirations, CST quickly became a specialist in advising clients on tax matters when moving abroad.

The road to Singapore

Our Singapore office opened in 2004, followed closely by our office in Los Angeles in 2010 and our United Kingdom office in 2020.

Initially services were provided to expats moving to Singapore or establishing a business in Singapore from Australia. Today, we provide international tax advice and accounting services to companies seeking to establish a presence in Singapore from around the world. Our focus is on managing the tax affairs of global founders moving to Singapore to establish or expand their business.
