We’re pleased to welcome back Fabiola Annacondia and Laura Alarcon Diaz from the International Bureau of Fiscal Documentation (IBFD) as our guest speakers for this online training session on VAT.

This session will provide an update on recent EU VAT developments, including two important documents published by the European Commission on 24 July 2026. We will look at the revised Explanatory Notes, updated following the VAT in the Digital Age (ViDA) reforms and reflecting changes coming into effect from 1 January 2027, as well as the updated One Stop Shop (OSS) Guidelines.

The second part of the session will take a more practical, case-based approach, exploring recent and ongoing VAT cases and their potential implications. Topics will include:

  • Joint VAT liability and input VAT deduction (pro rata for non-entrepreneurial activities) and retroactive invoice corrections (late invoicing / corrections for previous periods)
  • Relevance of transfer pricing adjustments (amendment of prices outside and within taxable supply scenarios) and
  • Intra-Community transactions including 4 party triangulation supplies and the impropriate use of VAT ID numbers.

The discussion will focus on the key issues arising from these cases and what they could mean in practice, including how their treatment may differ across jurisdictions. Share and benefit from each other!
