Market overview

Tax controversy has become one of the most demand-rich specialisms in the profession as Asia Pacific enforcement intensifies. IRAS in Singapore and the Inland Revenue Department in Hong Kong both run sophisticated, increasingly data-driven audit programmes, and APAC is now among the most active transfer-pricing and tax audit fronts in the world, with authorities tightening documentation requirements and using harder-hitting powers [1]. For global context only, EY's 2025 Tax Risk and Controversy survey describes rising audit volumes and longer settlement times worldwide, with a special focus on multinational groups [2].

That enforcement wave is generating a structural pipeline of controversy work across the region. In transfer pricing alone, the OECD recorded about 2,525 new mutual-agreement cases in 2024, up 29% year on year, and authorities run thousands of audits annually [1], and controversy support, audit defence and litigation-readiness have been among the fastest-growing service lines in Singapore and Hong Kong. Firms need partners who can manage a dispute from first enquiry through to settlement or litigation support.

The skill set is distinctive. Controversy leaders combine deep technical tax knowledge with the procedural and advocacy capability to handle revenue-authority dealings, alternative dispute resolution and litigation support, often working alongside counsel. Many of the strongest profiles carry the SCTP Accredited Tax Advisor or HKICPA standing together with legal training, and increasingly a facility with the data and technology that now sit at the centre of modern, AI-enabled audits [2].

Singapore, Hong Kong, Australia and the Gulf are all active enforcement environments with revenue authorities running advanced audit programmes. We run retained, highly confidential search for tax controversy partners and teams across the Big Four, mid-tier networks and independents, where discretion is paramount given the sensitivity of the client relationships involved.

Frequently asked

Why is tax controversy hiring accelerating in APAC?
Enforcement is intensifying across the region. IRAS and the Hong Kong IRD are running more sophisticated, data-driven audit programmes, authorities are focusing on multinationals and using harder-hitting powers, and AI-enabled audits are expanding the caseload. That creates a structural pipeline of controversy work and sustained demand for specialists in Singapore and Hong Kong.
What distinguishes a strong tax controversy partner?
The blend of deep technical tax knowledge with procedural and advocacy capability for revenue-authority dealings, alternative dispute resolution and litigation support. Many of the best carry both a regional tax credential - the SCTP Accredited Tax Advisor or HKICPA standing - and legal training, plus fluency with the data that drives modern audits.
How confidential are these searches?
Highly. Controversy mandates touch sensitive client relationships and live disputes, so we run them with strict discretion on both the client and candidate side, which is precisely why retained search rather than open advertising is the standard for these roles.
