General Terms and Conditions

Please read these terms carefully before using the Luxembourg FAIA Validator.

Last updated: March 2026

Important Notice

While we strive for accuracy, validation results should be independently verified before submission to tax authorities. This tool is a compliance aid, not a substitute for professional tax advice.

Not an Official Government Tool

This validator is not affiliated with, endorsed by, or officially connected to the Luxembourg Administration de l'Enregistrement, des Domaines et de la TVA (AED) or any other government authority. It is an independent tool that validates files against publicly available FAIA v2.01 XSD schemas.

By accessing or using the Luxembourg FAIA Validator ("the Tool"), you agree to be bound by these General Terms and Conditions. If you do not agree to these terms, please do not use the Tool. Use of the Tool implies full acceptance of these terms.

2. Description of Service

The Tool provides validation of FAIA (Fichier d'Audit Informatisé AED) files against the publicly available FAIA v2.01 schemas. All validation occurs securely with zero data retention. Your files never leave your device.

The Tool is currently offered as a free schema validation service. Additional paid subscription tiers with advanced validation features are coming soon. See our Plans page for details.

When you cancel or downgrade to the Free tier, your account will be downgraded at the end of your current billing period. Validation history and quota usage data may be retained for 90 days in accordance with our data retention policy.

7. Disclaimer of Warranties

THE TOOL IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that:

  • The Tool will meet your specific requirements
  • The Tool will be uninterrupted, timely, secure, or error-free
  • The validation results will be accurate, complete, or reliable
  • Any errors in the Tool will be corrected

8. Validation Results Not Legally Binding

Validation results provided by this Tool are for informational and guidance purposes only and are NOT legally binding. Interpretation of validation results remains entirely at the discretion of the relevant tax authority.

A successful validation ("pass") does not guarantee:

  • Acceptance by the Luxembourg AED or any other tax authority
  • Compliance with all applicable tax laws and regulations
  • Accuracy of the underlying financial data in your file
  • That your file is free from all errors or issues

Similarly, validation errors or warnings do not necessarily mean your file will be rejected by tax authorities. The Tool may flag issues that authorities might accept, or may not detect issues that authorities would reject.

You are solely responsible for ensuring your FAIA files comply with all applicable Luxembourg tax regulations and requirements. The user must submit their declaration to the relevant tax authority themselves. The Tool will never file on behalf of the user.

We reserve the right to reject a validation request if it falls outside the scope of the service or violates these terms.

12. Intellectual Property

The Tool and its original content, features, and functionality are owned by the Tool's creators and are protected by applicable intellectual property laws.

The FAIA v2.01 XSD schemas used by this Tool are publicly available documents published by the Luxembourg tax authority and are used in accordance with their public availability.

13. Binding Nature and Modifications

Use of the Tool implies full acceptance of these General Terms and Conditions.

We reserve the right to modify these Terms at any time. Changes will be communicated via email or through a prominent notice on our website upon your next login.
