Tax

RSM Singapore is a member of RSM International, an international network of independent audit, tax, and consulting firms. The network is connected globally and locally with offices across the Americas, Europe, MENA, Africa and Asia Pacific. The Singapore team headed by Koh Puay Hoon provides a wide range of tax practices such as cross-border investments and tax planning, corporate tax compliance and personal tax services, tax investigation and audit. Joanna Lam and William Chua are the key partners and cover transfer pricing and corporate and international tax areas respectively.

One recent example of the firm’s work saw it assisting a client in resolving and obtaining a bilateral advance pricing arrangement that involved US$1.6 million in tax savings.

The team recently added Law Wei Lin as the director for corporate and international tax practice. Partner Thomas Chan left the firm during the research period.
