Thanks skyflyer737, that helps already a lot, at least I get an idea. So that is with paying tax in Ireland and then the social contribution in Italy?
As an yearly average that is not bad, comparing to my present employer and finally being at home every night sleeping in my own bed. Tired of being away all the time and being shifted through various hotels for a lot of nights in a row per month.
Maybe someone based in Italy can give me some final confirmation, but the deal sounds ok for me. Especially since you are not required to pay for your own rating anymore. Don't mind the bonding.
