Community of Practice on Tax Expenditures

The Addis Tax Initiative (ATI), the Council on Economic Policies (CEP) and the German Institute of Development and Sustainability (IDOS) — the partners behind the Tax Expenditures Lab — have been cooperating to strengthen the transparency, governance, and effectiveness of tax expenditures (TEs) worldwide.

Together, they have conducted a series of workshops for finance ministries, revenue authorities, and parliamentarians, to build capacities, foster knowledge sharing and building regional networks of TE experts. These efforts aimed to strengthen institutional capacities to report, evaluate, and reform TEs effectively, supporting more evidence-based and transparent policies in the field and contributing to broader domestic revenue mobilisation (DRM) efforts.

Building on this momentum, the Community of Practice (CoP) on TEs was launched in October 2024 as a sustained platform for exchange, enabling participants and stakeholders to leverage collective expertise and promote better TE governance and management across institutions.
