The primary purpose of the inventory is to assist tax administrations in their considerations of possible domestic digitalisation and digital transformation reforms as well as to help identify where future collaboration between tax administrations might be of most value. The inventory seeks to achieve these aims by looking at (i) leading technology tools and digitalisation solutions implemented by tax administrations, and (ii) approaches that will help to advance the overall digital transformation of tax administrations.

In addition to providing a snapshot of which administrations have adopted particular technology tools or approaches, the inventory also contains links to case studies provided by participating tax administrations to provide a more in-depth look at particular implementation solutions as well as links to supporting materials and studies. 

• Access the case studies

The data underlying the inventory is collected through the Global Survey on Digitalisation which is completed by tax administrations. The data has not been reviewed or validated by the OECD or any of the partner organisations. As a result, all data should be considered as self-reported by the administrations concerned. The aim is to update the data in the future.
