I moved to Italy last year and worked for 3 months there before moving to Germany for another job and live here since July.
I will file a tax return here for sure (mainly because I know I will get a taxback since I was overtaxed one month for lack of local knowledge).
I don't really want to bother doing so in Italy though... I earned quite a low income during those 3 months (as a salaried employee) and if I had any tax to get back it would be very low anyway.
So all of my salary in Italy was as a salaried employee, but within the same year I got a second source of income which was my job in Germany (never at the same time, left one for the other) - also as a salaried employee.
So I have to file a tax return in Italy?
BTW, I'm an Italian citizen.
Edit: This is not a duplicate of Do Italian Citizens living abroad have to pay taxes to Italy? as that question asks in a very generic way if any citizen living outside the country need to file the return; my question is regarding a citizen who was a resident for a short period within the year and moved to another EU country.
