Will the G20 countries formally adopt a global minimum tax rate for high-net-worth individuals before the end of 2030?

Taxing the Global Wealthy

The G20 successfully achieved a global agreement on a **corporate minimum tax** (Pillar Two), demonstrating a rare level of international tax cooperation (OECD, simulated late 2025 context). However, extending this framework to a **global minimum tax for high-net-worth individuals (HNWIs)** faces much higher political resistance. Unlike corporate taxation, wealth taxation touches upon highly sensitive, nationally entrenched laws and privacy concerns. The strong 'No' vote is based on the political difficulty of achieving consensus among the diverse G20 nations on a wealth-based tax, making formal adoption **before the end of 2030** highly improbable.
