Sevilla, 2 July - The Organisation for Economic Co-operation and Development (OECD) and the United Nations Development Programme (UNDP) have presented today a new plan to expand the scope and global coverage of their shared Tax Inspectors Without Borders (TIWB) programme, marking a new phase in the flagship capacity-building initiative. 

Tax Inspectors Without Borders 2.0, presented during the Fourth International Conference on Financing for Development (FFD4), in Sevilla, Spain, will build on a decade of impactful collaboration between OECD, UNDP and governments worldwide while adapting its activities to the evolving challenges of international taxation. To date, the initiative has enabled countries to mobilise an additional US$2.4 billion in revenue, of which an impressive US$1.91 billion has been raised across Africa alone.

TIWB will continue its signature mission – the deployment of experienced tax experts to work side-by-side with domestic audit teams in developing countries, strengthening local capacity through real-time support in concrete audits and investigations. 

Haoliang Xu, Acting Administrator of UNDP: “Over the past decade, Tax Inspectors Without Borders has shown how strengthening tax capacity at the national level unlocks domestic finance for sustainable development. By providing technical expertise in tax administrations, TIWB has helped countries reclaim billions to advance the Sustainable Development Goals. When tax systems are fair, efficient, and inclusive, they do more than fund public services, they rebuild trust, strengthen the social contract, and weave sustainability into the fabric of governance. But we need to scale up. Continued investment in TIWB will be essential to sustain this momentum and mobilize domestic resources to advance sustainability.

TIWB 2.0 was selected to be among the Sevilla Platform for Action Initiatives at FFD4 – a group of initiatives aimed at achieving measurable progress by advancing the renewed financing framework of the Sevilla outcome document, supported by a set of concrete actions. 

Mathias Cormann, Secretary-General of the OECD, welcomed the launch of TIWB 2.0: “Looking ahead, we are optimistic that the Tax Inspectors Without Borders initiative will continue to adapt and respond to each jurisdiction’s specific needs and objectives, delivering responsive, country-led support that will improve tax administrations and boost domestic resource mobilisation. With ongoing donor engagement and reinforced partnerships, TIWB 2.0 is positioned to help developing countries strengthen tax capacity and meet the demands of a rapidly shifting global tax environment.”

The new developments were presented today at FFD4 during an event, “Tax Inspectors Without Borders: A Decade of Impact and the Road Ahead”, together with partners from the OECD’s Forum on Tax Administration (FTA), the African Tax Administration Forum (ATAF), the Intergovernmental Forum on Mining, Minerals, Metals and Sustainable Development (IGF), and the International Centre for Tax and Development (ICTD). 

Since its launch in 2015, TIWB has supported 70 developing jurisdictions, securing US$6.39 billion in tax assessments, including disallowed losses and deferred taxes, and collecting over US$2.4 billion in additional tax revenues. In Africa alone, through its close collaboration with ATAF, 39 countries have raised more than US$1.9 billion in additional revenues.

A 10-year retrospective report outlining these results and the initiative’s future direction was also launched today, capturing a decade of achievements and lessons learned.
