Brazil Finance Minister Dario Durigan said on Monday he is the first to support discussing a minimum global tax on the ultra-wealthy at the G7 [1].

This push for international fiscal justice aims to combat wealth concentration by establishing a standardized tax floor for the world's richest individuals. If adopted, such a measure could prevent tax avoidance and generate significant revenue for member nations.

Durigan said this in Paris, France, during preparatory meetings that lasted two days [2]. He positioned Brazil as a leader in this policy shift, citing the country's own 2025 tax reform as a viable model for other nations [3].

"I am the first to agree to the discussion of a tax on the ultra-rich in the G7," Durigan said [1].

The proposal comes as the G7 prepares for its official summit in France [1]. While some reports indicate the summit will take place in June 2026 [1], other accounts suggest the official meeting occurs in May [4]. Durigan is using the current diplomatic window to advance the agenda of global tax fairness.

By leveraging the 2025 domestic reforms, Durigan is attempting to provide a practical framework for how such a tax could be implemented without destabilizing national economies [3]. The focus remains on ensuring that the highest earners contribute a proportional share to public finances, regardless of where their assets are held.

"I am the first to agree to the discussion of a tax on the ultra-rich in the G7,"

Brazil's proactive stance suggests a strategic effort to lead the Global South in shaping international financial architecture. By referencing its 2025 tax reform, Brazil is moving from theoretical advocacy to offering a concrete policy blueprint, potentially pressuring G7 nations to address systemic wealth inequality through coordinated legislative action.
