Tax implications of talent mobility
Downloadable guides
In an era where talent moves as fluidly as capital, organisations are increasingly embracing cross-border mobility as a strategic imperative. Whether driven by business expansion, the evolution of remote work or the pursuit of specialised skills, the movement of employees across jurisdictions has become a defining feature of the modern workforce. Yet, with opportunity comes complexity – particularly in the realm of taxation.
We are pleased to introduce this guide on the tax implications of talent mobility, a comprehensive resource designed to help organisations, advisers and globally-mobile professionals navigate this intricate and ever-evolving landscape. Through a series of jurisdiction-specific articles, this guide will unpack the critical tax considerations that arise when employees live and work outside their home countries.
Tax trends in Asia: regional tax updates and perspectives on global developments
Webinar
The OECD’s two pillars, which address the tax challenges arising from the digitalisation of the economy, continue to drive tax changes on a global scale. In tandem, local tax laws and the economic environment are also rapidly evolving in many Asian jurisdictions. These are critical considerations for businesses and investments into Asia.
This webinar discusses and provides tax law updates on these salient topics, not only from the taxpayer’s perspective, but also from the tax authorities’ position.

This conference panel brought together practitioners from Europe and the US to examine how the market has developed, how policies are structured and negotiated, as well as what happens when things go wrong.
