Post Conference Highlights on International Tax Disputes Day: The Asian and Global Landscape, 22 May 2025

 "Singapore, if you think about the topic of tax certainty, is one of the capitals, the lighthouse of international tax certainty, one of the capitals where tax certainty isn't just talked about but it's lived. It lives in our Inland Revenue approaches, so there's a lot that the world can learn…”

“(Tax Academy of Singapore) is a great institution to have, it’s a great idea to bring practitioners together, to bring people from tax administrations, from universities together…”

Singapore stands as a beacon of tax certainty, where theory meets practice through IRAS' innovative approaches. At the International Tax Disputes Day conference on 22 May 2025, Tax Academy brought together over 200 distinguished professionals - including 70 senior partners and C-suite executives - to explore how tax certainty drives sustainable economic development. This high-level gathering exemplified our commitment to bridging expertise across tax administration, practice, and academia.

In his opening address, IRAS Commissioner and CEO Mr Ow Fook Chuen highlighted Singapore's practical commitment to tax certainty. From our extensive treaty network to proactive dispute prevention measures, Singapore is building a tax ecosystem that gives businesses confidence to operate in an increasingly complex global environment.

Dr Achim Pross's keynote highlighted APAC's distinctive approach to tax disputes: despite its significant economic weight - one-third of Inclusive Framework GDP - the region shows remarkably few MAP cases, demonstrating its success in dispute prevention over resolution.

The conference featured dynamic discussions from 19 distinguished speakers - a diverse mix of academics, practitioners, and policy makers from Singapore and overseas. Beyond intellectual discourse, the event provided an invaluable platform for networking, fostering connections between local and international tax professionals including students of Tax Academy NextGen awardees.

Tax Academy would like to thank all speakers, panellists, guests and participants for making this conference a success!
