DIGITAX Research Programme

The DIGITAX programme generated knowledge and evidence as well as delivered advice and support to governments and other stakeholders on overcoming challenges and leveraging opportunities at the interface of digital financial services (DFS), digital IDs, and tax.

Our robust, relevant, and cutting-edge research looked at:
• the taxation of mobile money and other DFS, and;
• the digitalisation of tax systems across lower-income countries, with a particular focus on Africa.

DIGITAX, which ran from 2020 to 2024, was funded by the Gates Foundation.
