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 Tax Advisors quickly became a specialist in advising clients on tax matters when moving abroad.

The road to Singapore

Our Singapore office opened in 2004 and initially provided services 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.
