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.

Treat-ease? Not if GAARs and the PPT can help it
The implementation of general anti-avoidance rules (GAARs) has been an attempt to prevent the use of tax treaties to enable tax evasion, granting a country’s tax authority enough power to disregard a particular corporate structure or transaction, and deny a benefit granted by a double taxation treaty when tax avoidance could exist. Even so, the task of GAARs comes with challenges, as the interpretation of ‘when’ and ‘how’ GAARs should be applied can vary from one country to another. This session at the 2024 IBA Annual Conference in Mexico City discussed the status on the implementation of GAARs in Brazil, Mexico, Switzerland and the Netherlands.

Structuring business investment into Mexico
This panel at the 2024 IBA Annual Conference in Mexico City addressed the main recent developments in the tax structuring of foreign investments into Mexico. Considering that such foreign investments are predominantly made by United States investors (41.4 per cent of investment over the period 2006–2024), and by Spanish investors (10 per cent of investment over the same period), the panel focused first on the main general tax implications arising in Mexico for foreign investors.

Mandatory reporting and the preservation of client rights to privacy, access and privilege
Mandatory reporting obligations adopted by different jurisdictions have created tensions between fundamental principles such as solicitor-client privilege, confidentiality and transparency. As countries implement stricter reporting regimes, different parties face challenges balancing compliance with these principles. This panel at the 2024 IBA Annual Conference in Mexico City discussed the approaches and current developments in different countries on these subjects.
