US hedge fund Millennium seeks tax deal to expand Geneva presence

By the Editorial Team · Wednesday, September 9, 2026

Hedge fund Millennium Management is negotiating with Geneva authorities for a favorable tax agreement to support the growth of its local office amid competition among Swiss cantons. If successful, the deal could attract more employees to Geneva, which recently lowered personal income taxes to better compete with lower-tax regions like Zug.

Hedge fund Millennium Management is engaged in talks with Geneva authorities to secure a favourable tax agreement that would support the expansion of its local office, amid intensified competition among Swiss cantons to attract wealthy individuals and firms.

Switzerland’s federal system grants cantons significant autonomy in setting tax rates, which they frequently leverage to draw high-net-worth residents and large companies. Geneva’s top personal income tax rates can reach approximately 45 percent, contrasting sharply with Zug’s rate of around 20 percent, where Millennium also maintains an office. The New York-based hedge fund, managing assets exceeding $92 billion and employing about 6,900 people globally, currently has a larger presence in Zug than in Geneva.

A successful tax ruling in Geneva could improve the canton’s appeal to Millennium’s employees, particularly traders and prospective hires who favour the French-speaking region. A tax ruling represents a legally binding agreement with cantonal authorities that can lower an effective tax burden for companies or individuals.

The ongoing rivalry among Swiss cantons was further highlighted recently when Vontobel, a private bank founded 102 years ago, announced plans to relocate its headquarters and around 1,500 staff from Zurich to Zug, where it will establish a new campus.

Historically one of Switzerland’s highest-taxed cantons, Geneva has been actively working to reduce the tax disparity with lower-rate competitors such as Zug. In November 2024, Geneva voters approved a significant cut in cantonal and municipal personal income taxes, which came into effect in 2025. The reforms have resulted in an average personal tax reduction of 8.7 percent, with the scale of cuts varying between 5.3 percent and 11.4 percent depending on income brackets. The Geneva government framed these changes as measures to enhance the canton’s competitiveness, though tax rates remain relatively high for top earners.

While housing shortages in Zug have made Geneva a more attractive location for some financial professionals, Geneva’s residential property market is even tighter. Federal data indicate that last year, Geneva had a vacancy rate of just 0.34 percent compared with 0.42 percent in Zug, underscoring the scarcity of available housing in both areas.

Millennium Management and Geneva’s finance department both declined to comment on the discussions.
