Each edition rates the transfer pricing expertise offered in various jurisdictions, giving transfer pricing executives the most comprehensive information about the market for transfer pricing advice.

Our research is entirely free and independent and no firm or professional can pay to be included.
Our rankings are based on three key criteria:

Work evidence

We ask all firms to provide deal and case highlights from their last 12 months of work.

Peer feedback

No one knows more about the tax market than those professionals who work in it.

We conduct a PRACTITIONER SURVEYof transfer pricing professionals to get their thoughts and feedback on our existing rankings.

All active legal transfer pricing professionals are invited to take part and we also speak to a great number of professionals through phone and face-to-face interviews.

Professionals cannot recommend their own firm or colleagues in their own firm.

Client feedback

We speak to a wide range of corporate and in-house contacts as part of our Client Feedback Survey to get their opinions on the firms and professionals they use.

We ask for feedback on the following attributes:

  • Technical ability
  • Accessibility and communication
  • Depth of team
  • Value for money
  • Client/lawyer relationship
  • International network

World Tax

International Tax Review publishes its own directory about advisers, lawyers and providers in that market. Please refer to it at www.itrworldtax.com if you are looking for more depth in this area.

The research for both World Tax and World Transfer Pricing is carried out in unison.
