There is a pressing need for global reform of inheritance taxation systems. On average, only 0.5% of total tax revenues are sourced from inheritance taxes across the 24 OECD countries that levy them. If designed properly, inheritance taxes could play a greater role in raising revenues for cash-strapped authorities seeking to overcome mounting public deficits.

In a historic agreement on 8 October 2021, 136 countries approved the OECD two-pillar solution in a major overhaul of the century-old international taxation system. At the G20 Summit in Rome on 30 October 2021, the leaders of the world’s biggest economies endorsed the two-pillar solution, decades in the making but which will be implemented in 2023.
