## CRS LUX: Module Overview

This guide provides information about the Luxembourg specific extension of the CRS module of the TRSuite software package. It describes processes and procedures for importing and exporting CRS OECD XML 2.0 files compatible with the Luxembourg schema extensions.

A note on the amended CRS, state as of September 2026. TRSuite writes the Luxembourg format defined by circulaire technique ECHA n° 4 of 10 August 2020, which envelops the OECD CRS XML Schema 2.0. Those arrangements remain applicable until 31 December 2026.

For the amended CRS the Administration des contributions directes has already published what is needed: the Manuel d’utilisation NCD, which replaces circulaire ECHA n° 4, and the schema package CRS_LUX_V3.0.zip. Both apply from 1 January 2027, and a pre-validation environment for the new CRS 3.0 schema is announced for 12 October 2026 so that institutions can test their systems beforehand. Under the law of 27 March 2026 the first report to the ACD under the amended rules is due by 30 June 2027 for the 2026 tax year.

This release of TRSuite does not yet produce the new Luxembourg format; it covers reporting under circulaire ECHA n° 4. Please consult https://impotsdirects.public.lu/fr/echanges_electroniques/CRS_NCD.html for the current schema and manual, and contact support@section11.ch for the planned availability of schema 3.0 in TRSuite.

Pressing the “Import AEOI XML” button (3) allows to import the data from an existing AEOI report (also previous version is supported).

- If the message reference and document reference IDs not yet generated you can check the “Generate IDs during export” checkbox, to generate (or replace) all message and document reference IDs during the export of the XML.
- Finally export the file by pressing (4). Select the target folder. The filename will be generated according to Lux naming conventions.
