How does the pre-filling of data in the myTax questionnaire work?

S-Net uses your identifying and product data, as well as the data detected and injected into your tax safe to pre-fill the myTax questionnaire. However, not all of this data will be included at the launch of the service and Spuerkeess will progressively enhance the pre-fill during the ongoing updates of S-Net.

In any case, Spuerkeess cannot guarantee the completeness of this pre-filling.

It is therefore essential that you check and validate all the pre-filled data throughout the questionnaire and adapt or delete them if necessary.

We also encourage you to validate the content of the various forms generated before signing them and sending them to the Luxembourg tax authority..

Please refer to the myTax Terms of Use for more information.
