The Fair Tax Foundation was launched in 2014 and operates as a not-for-profit social enterprise, based in Manchester. The Fair Tax Foundation believes that companies paying tax responsibly should be recognised and celebrated; and any global race to the bottom on tax competition should be resisted. Tax contributions are a vital part of the broader social and economic contribution made by businesses, helping the communities in which they operate to deliver valuable public services and build infrastructure that paves the way for growth.

The Fair Tax Mark accreditation scheme is the gold standard of responsible tax conduct. It seeks to encourage and recognise organisations that pay the right amount of corporation tax at the right time and in the right place. Accredited businesses in the Fair Tax Mark movement include listed PLCs, co-operatives, social enterprises and large private businesses. Some one hundred parent companies and 250 distinct trading businesses are currently Fair Tax Mark accredited, who between them employ over 250,000 and contribute more than US$1.5bn in corporation tax annually.

A Fair Tax Global Multinational Business Standard was launched in 2021, enabling multinationals headquartered outside of the UK to be accredited for the first time. Companies have now been certified in Denmark, Italy, Germany, the Netherlands and Sweden.

The Fair Tax Foundation also runs other initiatives, including Fair Tax Councils and Fair Tax Week.
