Hedge fund Millennium Management is in discussions with Geneva authorities to secure a tax deal and expand its office in the Swiss canton. The New York-based fund, managing over $92bn in assets and employing about 6,900 people, already operates in both Geneva and Zug, where maximum personal income tax rates are roughly 20 per cent versus 45 per cent in Geneva. A favourable tax ruling would enhance Geneva's appeal for Millennium's traders and potential hires who prefer the French-speaking region.

Geneva voters approved an 8.7 per cent average income tax cut in November 2024, effective 2025, to improve competitiveness, though the canton remains expensive for top earners. Negotiations can yield binding tax rulings reducing effective burdens based on jobs, payroll, and investment. Housing scarcity in Zug is driving demand for Geneva, yet Geneva's residential vacancy rate is even lower at 0.34 per cent versus Zug's 0.42 per cent.

The rivalry among Swiss cantons intensified recently when private bank Vontobel announced plans to move its headquarters and 1,500 employees from Zurich to Zug. Millennium declined to comment; Geneva's finance department stated relocating individuals receive no preferential tax treatment.
