As a cross-border worker, can I use MyGuichet.lu?

Yes. Cross-border workers from France, Belgium, and Germany can use MyGuichet.lu to submit their Luxembourg tax return and other administrative documents, provided they have a valid LuxTrust authentication method.

Access to MyGuichet.lu, as well as the electronic signature and submission of documents, strictly requires a secure LuxTrust login, including for cross-border workers. Without LuxTrust, MyGuichet.lu cannot be used.
