The OECD has opened registration for its virtual Tax and Development Days on 17–18 June 2026, bringing together policymakers, tax administrators, and civil society to examine how stronger tax systems and improved compliance can advance development outcomes in lower-income countries.
The OECD has announced that registration is now open for the OECD Tax and Development Days 2026, a virtual event scheduled for 17 and 18 June 2026.
This event provides an update on OECD initiatives to strengthen tax capacity, enhance tax policy, and improve compliance in developing countries, while also exploring future challenges.
The OECD Tax and Development Days 2026 will bring together policymakers, tax administrators, international and regional organisations, as well as representatives from
business and civil society, to explore how stronger tax capacity, better tax policy and improved compliance can deliver greater development impact in developing countries.
Under the overall theme From Rules to Results: Turning Tax Policy into Development Impact, this year’s programme explores how greater tax certainty and simplification, stronger trust and transparency, improved tax administration, better use of data and effective partnerships can help countries strengthen tax systems, mobilise revenues and support sustainable growth.
All sessions are open to all stakeholders, including the media, and will take place virtually, on Zoom.
French and Spanish interpretation will be available throughout the event.
