Vision and Mission

Millionaires for Humanity advocates for 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 with all stakeholders, such as the UN, governments, finance think tanks, and grassroots organizations.

How we work

Millionaires for Humanity’s advocacy for wealth taxation occurs both at the national and international levels. At the national level, we work with credible local actors, who are already engaged in tax justice issues and addressing inequality in their respective countries.

In partnership with these local actors, we help spur discussion around wealth taxes through the promotion of wealth tax poll results that reveal resounding in-country public support for a wealth tax, even across political party lines. In this promotion, where feasible, we add the voices of our members, highlighting the full support of millionaires for wealth taxation. This is then followed-up by further advocacy work, depending on the viability of introducing a wealth tax in the country

At the international level, we work with peers and allies, who are lobbying international organizations and fora to address inequality, as well as the financing gap for the SDGs. This includes engagement with the OECD, the EU and the UN.


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, so we are aware of our responsibility. When we support a tax on people like us, we are amongst the most effective advocates for it.
