Tax trends in Asia: regional tax updates and perspectives on global developments

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.
