About SAF-T Validator
Professional Standard Audit File for Tax (SAF-T) validator for Luxembourg FAIA electronic audit files
What is FAIA?
FAIA (Fichier d'Audit Informatisé AED) is Luxembourg's implementation of the OECD Standard Audit File for Tax (SAF-T) framework. This standardized electronic audit file format is required by the Administration de l'Enregistrement, des Domaines et de la TVA (AED) for tax compliance, VAT reporting, and audit purposes.
Businesses operating in Luxembourg must be able to generate FAIA-compliant XML files containing their accounting and transaction data when requested by tax authorities. Our validator ensures your files meet all official requirements before submission.
