Advancing tax administrations in Europe

We are a non-profit organisation with 44 member countries in the European region. We bring tax administrations closer together so they can share best practice – helping them become more effective and efficient in collecting tax, ensure taxpayer compliance and deliver taxpayer services to the highest professional standards.

The Good Practice Guide on Applying Data and Analytics in Tax Administrations

The Good Practice Guide on Applying Data and Analytics in Tax Administrations offers you wide selection of insights of more than ten European countries in data management, predictive modelling, social network analysis, data visualisation, random audits, web scraping, etc. Read our innovative and online Guide and gain useful information from this collection of good practices.

Modern tax systems – digital technology
