Tax Controversy & Disputes Search

Tax controversy has become one of the most demand-rich specialisms in the profession as enforcement intensifies worldwide. EY's 2025 Tax Risk and Controversy survey and parallel KPMG and OECD analysis describe rising audit volumes, longer times to settle and a special focus on multinational groups and large domestic taxpayers, with authorities using harder-hitting powers such as formal access rights, interviews and summonses [1]. Cash-strapped governments and AI-enabled, data-driven audits are accelerating the trend [2].

That enforcement wave is generating a structural pipeline of controversy work. In transfer pricing alone, close to 1,000 new cases enter mutual agreement procedures each year and governments run thousands of audits annually, and controversy support, audit defence and litigation-readiness have been among the fastest-growing service lines [3]. 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 a chartered tax qualification together with legal training, and increasingly a facility with the data and technology that now sit at the centre of modern audits [2].

Asia Pacific and the Gulf are active enforcement environments, and Singapore, Hong Kong and Australia all have revenue authorities running sophisticated 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.
