UPDATE: a more recent version of the Global Tax 50 is available.
Last year, the OECD's top tax man, Pascal Saint-Amans, was chosen by us as the world's most influential person in tax. Indeed, many of the people featured in this list are policymakers and politicians, for the sheer power they wield.
This year, however, the global tax agenda has rather run away from policymakers and they are struggling to play catch-up with increasingly vocal demand from the public and the media to crack down on tax avoidance.
Reflecting this, the surprise number 1 spot goes jointly to Starbucks, Amazon and Google. The avoidance scandals involving these three household names shook up the tax world and set the pace and direction of policy change, bringing country-by-country reporting, automatic information exchange and transfer pricing reform to the fore. The three multinational companies may not have had the influence they might have chosen, but they have had a big impact nonetheless.
Our Top 10, listed in order of influence, is available exclusively online, while in the magazine you will find our complete Top 50, listed in alphabetical order.
We welcome comments on our Global Tax 50. Please tell us if you agree or disagree, and who you think should make up next year's list.
Be sure to check out our LinkedIn and Twitter platforms to take part in these live discussions.
You can also compare this year's list against last year's list and the 2011 list.
