Tax Justice UK is a prominent campaigning and advocacy organization dedicated to advancing progressive tax reform across the UK. Focused on creating a fairer tax system, the organization advocates for higher taxation on the wealthy and excessive corporate profits to effectively tackle the pressing issues of inequality, crumbling public services, and the climate crisis. Their mission is to redistribute wealth in a manner that funds high-quality public services, while also ensuring that tax policies support environmental sustainability rather than subsidize harmful practices.

With a values-driven approach grounded in courage, equity, and integrity, Tax Justice UK aims to build a robust tax justice movement that influences public dialogue and secures political support for reform. Supported by over 60,000 public members and a variety of organizations, Tax Justice UK operates as a not-for-profit and is politically neutral. The organization collaborates with the Tax Justice Network while maintaining its independence, working tirelessly towards a transformative vision of a fairer and more effective tax system for all.
