Ciao, ho iniziato a lavorare in Lussemburgo l’anno scorso e attualmente sto pagando le tasse su [guichet.lu](http://guichet.lu), per procedere ulteriormente dovrei mettere un numero di serie di 11 numeri chiamato “numéro de dossier” sfortunatamente non riesco a trovare il numero. Pensavo fosse il mio numero di previdenza sociale, ma no. Hai idea di dove trovarlo? ty

It is a number that the ACD (tax administration) assigns you. You can find it on the letter they send you in which they tell xou that you need to do your tax declaration. Or they can probably tell you the number if you ask them
If you are declaring for the first time, you’ll be assigned the number when you submit.
Might be that you have to do it the old-fashioned way the first time and not via myguichet if myguichet will not let you submit without it. I say this as I seem to have a recollection that it is an optional piece of data.
You don’t need to complete it in the first return. Afterwards, you will get the number and will need to use it in year 2 onwards
