Who this suits
CST is a tax and accounting firm focused on businesses operating in Singapore and expatriates relocating to the region, offering corporate and international tax advice, company secretarial work, audit, employee-tax management, company registration and expatriate tax returns. The expatriate-tax focus is the distinguishing feature: it suits an inbound founder or posted employee who needs both the company and their personal Singapore tax handled together.
Singapore has no statutory licence for tax advisers, so the credential to look for is a Public Accountant registration (for any audit) and, for advisory, the voluntary Accredited Tax Advisor designation from Singapore Chartered Tax Professionals.
