EY Global Tax Controversy Flash Newsletter (Issue 89) | Tax controversy at a turning point: Key insights from the 2025 EY Tax Risk & Controversy Survey

The 2025 Tax Risk and Controversy Survey reveals a global tax environment undergoing rapid transformation, shaped by accelerating regulatory change, expanding transparency requirements and an increase in cross-border disputes. Drawing on the perspectives of 1,934 senior tax and finance executives, the survey highlights how organizations are navigating mounting pressures —from BEPS Pillar Two implementation to the resurgence of disputes over digital services taxes — while seeking more consistent, technology-enabled ways to manage controversy. Nearly 70% of tax functions have already deployed GenAI tools, and 87% believe these technologies will make audits and dispute resolution more efficient, accurate and timely. At the same time, the survey underscores the critical role of strong governance, with many companies acknowledging gaps in oversight, data readiness and enterprise-wide coordination. Together, these findings illustrate a pivotal moment for multinationals preparing for a more complex tax landscape. Access the full 2025 Tax Risk and Controversy Survey for deeper insights.

Additionally, join our webcast, Discover insights from the 2025 EY Tax Risk & Controversy Survey, where our panelists will discuss the survey, as well as action items and benchmarks for navigating emerging challenges. Two sessions of this webcast are available, each featuring similar content tailored to regional nuances: Tuesday, 24 February at 10:00-11:00 a.m. EST, and Wednesday, 25 February at 3:00-4:00 p.m. Beijing/Hong Kong Time.
