Independent Senior Tax Counsel to Regan van Rooy

Dr Erasmus has joined forces with Regan van Rooy, in collaboration with its South African and African tax teams, as an independent senior tax counsel in its Tax & TP Disputes and Litigation offering.

This collaboration brings together tax advisory, transfer pricing and litigation capability in one coordinated disputes team. For many businesses, tax disputes are managed in silos: a tax advisor handles the technical analysis, while legal counsel is brought in only after the matter has already escalated. The Regan van Rooy model takes a different approach by integrating tax and litigation strategy from the outset.

The offering supports clients across the full dispute lifecycle, including risk identification, audit engagement, dispute escalation, litigation strategy and resolution. It is designed for businesses facing tax audits, transfer pricing challenges, cross-border reassessments, documentation disputes, tax court proceedings and multi-jurisdictional controversy across South Africa and the African continent.

Dr Erasmus contributes his experience in senior tax litigation, transfer pricing trials, tax dispute management and strategic controversy resolution. His role strengthens the offering by ensuring that tax disputes are not approached as isolated technical disagreements, but as structured legal, evidentiary and strategic matters requiring early preparation and coordinated execution.

Books and Thought Leadership

Dr Erasmus is the author of several influential works on tax risk, tax governance and transfer pricing litigation, including Tax Intelligence: The 7 Habitual Tax Mistakes Made by Companies and his latest contribution, Conducting a Transfer Pricing Trial.

His publications draw on practical dispute experience and are used by tax professionals, advisors, students, and business leaders seeking to understand how tax risk becomes tax controversy and how controversy should be managed before it reaches litigation.

Through TaxRiskManagement.com, the Academy of Tax Law and his collaboration with Regan van Rooy, Dr Erasmus continues to focus on one central objective: helping organisations manage tax risk before it becomes a crisis, and helping them defend their position effectively when a dispute cannot be avoided.

Transfer Pricing On Trial (eBook)

Having prepared and argued at numerous transfer pricing trials, I thought committing my journey and experiences to paper was a good idea to guide others on this path.
