Why can’t I upload my 2024 tax return on MyGuichet.lu?
The Luxembourg tax administration is currently experiencing technical issues with the processing of the official PDF form (Form 100).
As a result, it is not possible to upload the tax return via MyGuichet.lu, regardless of the software used to generate the form.
What can you do in the meantime?
As long as the issue persists, we recommend that you print, sign, and send your tax return by post to your relevant tax office.
As soon as the upload option on MyGuichet.lu is available again, we will inform you right away.
