Global mobility, the regime of
attractions for individuals and the
proposal for global minimum wealth tax
on ultra-high net worth individuals

IBA,The New Era of Taxation Conference, 2025, Milan

In a context of increasing global mobility and tax competition, several jurisdictions have introduced preferential regimes to attract high-net-worth individuals (HNWIs), digital nomads, and internationally mobile professionals. At the same time, the debate around a global minimum wealth tax, particularly targeting ultra-high net worth individuals (UHNWIs), has gained momentum in international fora. The panel analyzes the interaction between national attraction regimes and the emerging international tax policy agenda, including the legal, political, and technical challenges of designing and implementing a coordinated approach to wealth taxation.

From a Swiss perspective, current topics discussed were: lump sum taxation (with pitfalls and tips and tricks), special Swiss domestic tax residency requirements as well as Swiss specificities regarding residency permits.
