Technical Support Instrument

Supporting the Digital Transformation of Tax and Customs Administrations


The benefits of digitalisation of tax and customs administrations are widely acknowledged across the European Union and by the Member States. In an increasingly digital world, tax and customs administrations face strong stakeholder demand to provide responsive services in real time. Information technology (IT) will make tax and customs systems simpler, more transparent, and more efficient, ultimately improving the environment for businesses and individuals, as well as for national administrations by enhancing their operational capacities.

Digital tools enable national administrations to address various needs, they enable fast sharing  and processing of information, while also ensuring that their design takes account of  financial, security and safety risks, prevents tax avoidance and evasion, and prevents customs and tax fraud effectively.


To support Member States’ tax and customs authorities in the development and implementation of their digital reform agenda. The overall objective of the flagship is to strengthen IT governance, improve IT services; build new digital skills; and strengthen the link between digital transformation and tax policy. ​

More specifically, the flagship would aim to:

  • Improve the performance and the quality of the national tax and customs related IT systems, national components of the core EU information systems, and ensure interoperability and compliance of these national system elements with common systems and requirements at EU level;
  • Expand and improve the e-services provided to businesses, to the public, to partner organisations and public bodies;
  • Increase the effectiveness and efficiency of the actions against tax avoidance and evasion, and customs and tax fraud through implementation of data-driven digital tools for business intelligence and investigations.​
