The African Tax Administration Forum (ATAF) generated $907.8 million in tax assessments across its member countries in 2025 through targeted audit interventions, with $685.8 million of that figure successfully collected — figures that underscore both the scale of untapped domestic revenue on the continent and the growing operational reach of the pan-African tax body.

The data is contained in ATAF’s 2025 Annual Report, released this week, which documents a year the organisation describes as one of significant institutional progress and expanding continental influence.

The headline numbers carry a pointed message at a moment when African governments are confronting a tightening global aid environment and rising pressure to reduce dependence on external financing. ATAF’s executive secretary, Mary Baine, was direct in her assessment: domestic resource mobilisation is no longer a development aspiration for African states — it is an existential fiscal imperative.

“Domestic Resource Mobilisation is no longer optional for Africa; it is the foundation for sustainable development, economic resilience, and fiscal sovereignty.

As external financing declines and fiscal pressures intensify, African countries must strengthen tax systems to modernise revenue administration, and build fiscally resourced states that finance development with integrity, effectiveness, and measurable results.” — executive secretary, Mary Baine, ATAF said.

Beyond the audit revenue figures, the 2025 annual report documents ATAF’s technical assistance footprint across the continent.

The organisation said it provided technical support to 35 countries during the year and trained 2,433 tax officials drawn from 43 member and partner countries — a capacity-building volume that positions ATAF as one of the most active technical assistance providers in African public finance.

The report also records ATAF’s support for legislative and administrative tax reforms across multiple jurisdictions, though it does not itemise the specific countries or reform measures in the summary release.

The annual report covers progress across six strategic pillars: capacity building, technical assistance, research, digital transformation, international tax cooperation, and institutional strengthening.

The breadth of that agenda reflects ATAF’s evolution from its origins as a training and knowledge-sharing body into a full-spectrum tax administration support institution with a recognised seat at global policy tables.
