Welcome to the Tax Controversy Leaders guide from World Tax, in association with the International Tax Review. This is the ninth annual publication of the list of the world’s leading tax controversy practitioners and is the most comprehensive edition yet, as we continue to grow the guide in both scope and scale. It covers more jurisdictions, reaches out to more individuals and recognises more practitioners than ever before – from rising stars just making a name for themselves to market leaders with decades of experience behind them.

Our research is now wider and deeper than ever:

  • More than 9,900 professionals surveyed
  • More than 1,500 tax experts ranked

All the latest Tax Controversy Leaders can be found here:







These individuals are nominated by their peers and the wider market and are recommended as trusted advisers. We ask tax professionals to name the people they would refer their clients to in the event of a conflict, or recommend as a local representative in another jurisdiction. Consumers of tax services also provide feedback regarding which individuals they consider to be the leading names in the market. The resulting list is therefore a collection of tax controversy leaders recognised – by the leading names in their own and international markets – as those who perform strongest in their field. Market leaders chosen by market leaders.

Do you agree with our findings? If not, there is still time to take part in the PRACTIONER SURVEY, where you can provide your feedback

As part of our extended coverage we also offer online profiles for those included this year. These allow practitioners to showcase their work to clients, offer more information about their skills and experience and display feedback collected by our research team from a broad range of industries.

Our aim always is to progress the guide, reach out to more practitioners, receive feedback from more clients and provide coverage of more leaders from every market. We would like to thank those who took the time to provide feedback to help us put this guide together this year and would encourage everyone to do so in the future to ensure we are providing the broadest, most accurate assessment of the leaders in tax controversy that we can.
