Welcome to the 2021 edition of World Tax, the comprehensive guide to the world’s leading tax firms.

Produced in association with the International Tax Review, it provides rankings and profiles of the most effective tax practitioners in the world, covering almost 90 jurisdictions located on every continent.

And, because tax practitioners work in a wide a range of disciplines, our rankings include law firms, consultancies and advisory groups. This ensures the broadest, most far-reaching coverage of any guide covering the global tax market.

This year's research involved:

  • Reaching out to more than 10,000 clients for feedback
  • Reaching out to more than 2,700 practitioners for feedback

The results include:
