High-level launch of the ATI Declaration 2025

Official side event at the 2021 ECOSOC Financing for Development Forum

Programme & registration

More than five years have passed since the launch of the Addis Tax Initiative (ATI) at the Third International Conference on Financing for Development in 2015. Over this time period, the ATI has evolved into an increasingly important player in the field of tax and developing, accounting for 62 member countries and supporting organisations to date. The ATI has significantly contributed to the implementation of the Addis Ababa Action Agenda and is firmly anchored within the Financing for Development (FfD) process.

The new ATI Declaration 2025 was developed last year by the members of the initiative in a highly participatory and inclusive process. This new partnership agenda reflects members’ common vision of a world where partner countries can generate sufficient domestic revenues in an equitable, accountable and transparent manner to fulfil the promise of the 2030 Agenda for Sustainable Development. Members of the ATI believe that tax systems can provide manifold benefits to societies and economies by promoting economic growth, strengthening gender equality and empowering minorities, protecting the environment, and reducing inequalities.

The ATI Declaration 2025 will be officially launched in a high-level side event during the 2021 ECOSOC Forum on Financing for Development. The event will serve as an opportunity for members of the ATI to strengthen high-level commitment to domestic revenue mobilisation (DRM) as means to finance sustainable development and close recognised gaps in development finance.
