International tax learning? Nata problem at IFA 2025 Lisbon

8 Oct 2025

ADIT Academic Board Chair Jim Robertson, ADIT Manager Rory Clarke, and DITT & ADIT Education Officer Sophie Briggs promoted the CIOT’s international tax qualifications at the 77th International Fiscal Association (IFA) Annual Congress in Lisbon from 5-9 October.

More than 2,200 tax leaders and practitioners from around the world attended the Congress, and our ADIT and DITT qualifications were of high interest to attending delegates across the five-day event.

Corporate tax residency and the prevention of treaty abuse were at the centre of the Congress programme, which featured plenary sessions on these crucial subjects involving Academic Board members Philip Baker and Luís Eduardo Schoueri respectively. Fellow Board member Diane Ring, meanwhile, was among the speakers leading a seminar on recent global tax developments.

The implementation of Pillar Two was also a key topic on the agenda and at the forefront of delegate conversations, providing an excellent platform to promote our brand new ADIT Pillar Two Award, a standalone qualification launching at the end of 2025. ADIT’s continued development to meet the future learning needs of tax professionals was also explored with a meeting of the Academic Board, at which Jim, Diane, Luís and Philip were joined by Sarah Blakelock, Jonathan Schwarz and Jefferson VanderWolk.

We also had the pleasure of meeting with a number of past and present ADIT and DITT students from across the globe who were among the attending delegates, sharing their personal experiences of our qualifications and their acquired skills in managing tax across borders and emerging technologies.

We exhibited alongside the International Tax and Investment Center (ITIC), a US-based research and education organisation that promotes initiatives to encourage investment in transition and developing economies. Lisbon marked the third IFA Congress at which the CIOT has partnered with ITIC, and we look forward to continue collaborating with them in the future, as an organisation that shares our goal of promoting tax learning and best practice around the world.

If you participated in the Congress, we hope you enjoyed it and we look forward to promoting ADIT and DITT at future IFA events. To stay in touch, you can email Rory and the team at [email protected].
