Tax controversy

Tax has become increasingly connected — governments are collecting and sharing taxpayer information, and tax changes in one jurisdiction can now trigger changes across the globe. The result is that tax controversy is evolving from two-sided disagreement in specific countries into a multidimensional, multi-country dynamic.

EY's Tax Controversy team supports clients with end-to-end solutions for navigating complex tax disputes and regulations. The team's integrated approach, combining Tax and Law expertise, ensures tailored services that manage audits, investigations, and cross-border issues effectively. This strategic guidance minimises financial and reputational risks, empowering businesses to confidently address tax controversies and focus on their growth.

What EY can do for you

Businesses must act so that their people, policies and systems are keeping pace. They need a line of sight into the issues and the potential for future tax controversy as well as a centralised global strategy. Should disagreements arise, having resources that can act as a “bridge” between the tax authorities and the company is essential.

Take a look at our insights, including leading practices on implementing a globally integrated approach to tax controversy management.
