Vision and Mission

Millionaires for Humanity advocates a wealth tax of 1% on multimillionaires to support the COVID-19 recovery, tackle poverty and climate change and achieve the UN Sustainable Development Goals.

Research by the UN Sustainable Development Solutions Network highlighted the funding gap for the world to meet the Sustainable Development Goals and the resources that a 1% wealth tax could raise to help enable this.

Millionaires for Humanity aims to help address this funding gap in partnership with all stakeholders, such as the UN, governments, finance think tanks, and grassroots organisations.


A tax on multimillionaires is vital to overcome the impacts of the COVID-19 crisis, reduce inequality, and enable a fairer, more secure, and happier society. It is in everyone’s shared interest. 

We experience that when we –  the multimillionaires – speak, decision-makers, media and the public listen, and so we are aware of our responsibility. When we speak out in support of a tax on people like us, we are amongst the most effective advocates for it.
