MTIC Gap 2026 – Update of the Intrastat-based Methodology
The main objective of the study is to reduce uncertainty regarding both the scale of MTIC fraud in the European Union and the most robust methodological approaches for measuring it. The project builds on the Commission’s 2024 analytical work, which assessed alternative estimation methods and tested a machine-learning-based approach using Intrastat mirror statistics for EU trade in goods covering the period 2010–2023.

The challenges of VAT beyond VAT in the Digital Age
This study should consider possible improvements to the EU VAT system and assess their feasibility and likely consequences, based on the analysis of its current weaknesses, gaps, inefficiencies. As requested by the ToR, this requires a forward-looking analysis and prospective reflection, combined with and based on the retrospective assessment of the current situation. The study requires, on the one side, a thorough re-assessment of well-known problems of the EU VAT systems, which have been discussed for years by policymakers, scholars and in courts and tribunals, the solutions to which have already been long proposed in the academic as well as policy arena. On the other side, it requires a fresh view to identify new solutions to old problems, new problems and their possible solutions, as well as potential unknown problems, i.e. those that may appear in the future given the current economic, political and legal evolution and the megatrends of the EU and global society. Operationally, the activities needed to achieve the objectives of the study are straightforward. For each of the areas or angle of analysis, the study team will have to: Identify existing weaknesses and challenges of the EU VAT system, including those that may appear in the future given the likely evolution of the current situation. Design solutions to the problems identified. Assess the feasibility and consequences of the solutions identified.

Digital Resilience of Children and Young People in Rural Areas
The main objective of the project is to strengthen digital resilience among children and young people in rural areas. Experiencing online risks has become an inherent part of growing up today. Research shows that children and adolescents most often cope with such challenges on their own, without support from adults. As contact with digital risks is unavoidable, it is important to develop children’s digital resilience – including critical thinking, coping strategies, and the ability to seek help when needed.
