The importance of a fair, efficient and effective tax system is clear. Domestic tax revenues are the largest and most important source of financing for sustainable development. Tax revenues can reduce poverty, increase equity, provide essential public goods such as education and health, correct market failures, and generate economic growth and better opportunities for all. The success of a TIWB Programme is reliant on the participation of all key stakeholders including Host Administrations, Experts, Partner Administrations and global Donor Partners.

Recently retired, current, or former tax audit experts with experience working in national tax administrations.

Partner Administration

Tax administrations who want to contribute, via secondment, currently serving tax officials to be Experts for a TIWB Programme.
