Three Singapore doctors fail in court challenge against IRAS ruling over tax avoidance scheme

Three specialist doctors in Singapore have lost a High Court challenge against the Inland Revenue Authority of Singapore (IRAS) regarding a tax avoidance scheme involving low salaries and high dividends. Justice Alex Wong dismissed the application on June 18, ruling that the doctors—Adrian Tan Chek Jin, Caroline Khi Yu May, and Jocelyn Wong Sook Miin—structured their business entities primarily to reduce their tax liabilities.

Did You Know? Before moving into private practice, Dr. Adrian Tan Chek Jin earned a monthly salary of S$45,600, a figure that dropped to S$5,000 once he began drawing a salary from the company he jointly established with his colleagues.

Court Findings on Tax Avoidance

The High Court upheld a previous decision by the Income Tax Board of Review, which found that the doctors’ business structure fell under a provision of the Income Tax Act. This provision allows IRAS to disregard arrangements designed to counteract tax advantages. According to the court, the doctors operated a series of jointly and individually owned companies, through which they paid themselves modest salaries while extracting millions in tax-exempt dividends and interest-free loans.

Justice Wong noted that while Dr. Tan’s initial salary could be partially explained by his transition to private practice, he failed to explain why his compensation remained stagnant as the business became increasingly profitable. During the 2013 to 2018 assessment years, Dr. Tan received S$5.14 million in dividends from one firm and S$2.35 million from another, alongside significant shareholder loans. The judge concluded that these payments pointed to tax avoidance as a primary purpose of the business arrangement.

Expert Insight: Samantha Carter notes that this case highlights the growing scrutiny tax authorities place on the fragmentation of business entities. By restructuring into multiple companies, professionals may inadvertently trigger anti-avoidance provisions if the primary motivation is deemed to be the exploitation of tax rebates rather than legitimate operational requirements.

Evolution of the Medical Practice

The doctors, who previously worked together at KK Women’s and Children’s Hospital, began their private practice in 2004 by incorporating ACJ Women’s Clinic (ACJW). Over the following decade, they engaged in two rounds of corporate restructuring. This included the creation of individual medical and surgical companies, such as AT OG Services, CKYM Holdings, and JW Medical Holdings, as well as individual surgical firms for each doctor.

These entities allowed the trio to claim tax rebates under the Start-Up Tax Exemption and Partial Tax Exemption schemes. In 2016, the doctors attempted to strike off several of these companies. IRAS objected to the process and initiated tax audits, eventually issuing amended income tax assessments in 2019 to recover the tax benefits that had been obtained through this fragmentation.

Potential Implications

Following the High Court’s dismissal of the appeal, the doctors may face significant financial consequences regarding their past tax filings. IRAS has already issued amended assessments for the years 2013 to 2018 and clawed back benefits for the 2015 assessment year. It is possible that the tax authority will continue to monitor the professional practices of high-earning individuals to ensure that business structures reflect actual operational needs rather than tax-minimization strategies. Other medical professionals who utilize similar corporate structures may face increased scrutiny during future audits.

Frequently Asked Questions

Why did the doctors lose their High Court challenge?
The court found that the doctors’ corporate structure was designed to avoid or reduce tax, allowing IRAS to invoke provisions in the Income Tax Act to disregard the arrangement and tax the income in the doctors’ individual names.

What role did the “Start-Up Tax Exemption” play in this case?
The doctors established multiple individual companies, which allowed them to claim tax rebates under the Start-Up Tax Exemption and Partial Tax Exemption schemes, a practice IRAS later identified as a primary reason for the business fragmentation.

What is the significance of the “claw-back” mentioned by the authorities?
The claw-back refers to the action taken by IRAS in December 2019 to recover tax benefits that the doctors had previously claimed, effectively nullifying the tax advantages derived from their multi-company business structure.
