The United Nations University – World Institute for Development Economics Research (UNU-WIDER) in collaboration with the Addis Tax Initiative (ATI), is launching a Tax Gap Toolkit on 10 December 2024. This innovative toolkit allows tax authorities and policymakers to regularly and systematically estimate tax gaps for value added tax, corporate income tax, and personal income tax.

A launch event is organised on 10 December, at 2pm (CET) to introduce the Tax Gap Toolkit and demonstrate its features and functionalities. A discussion led by the International Monetary Fund (IMF) will follow to explore the potential impacts of the toolkit on tax policy and administration.

 

About the toolkit

Mobilising domestic revenue is crucial for supporting economic growth, reducing inequalities, and providing essential public services, and efficient tax systems are essential for achieving this goal. Tax gap analysis is a critical component of this effort.

The Tax Gap toolkit is a global public good developed in partnership with the Addis Tax Initiative, to support the realisation of the ATI Declaration 2025. The toolkit estimates the difference between the potential tax revenue and the actual tax revenue collected, providing revenue authorities and policymakers with a measure of the amount of tax revenues lost or forgone due to non-compliance. Conducting a tax gap estimation enables authorities to inform better allocation of limited resources and develop strategies to combat or reduce significant tax gaps and improve tax collection.

The toolkit builds on UNU-WIDER research in Zambia and Tanzania under their Domestic Revenue Mobilisation programme.
