Thanks Sarah - I have checked and currently on our intranet system there is some info for the French and German based crew, but there is no specific advice for Milan-based employees. Some enquiries have been made and the situation at the moment is essentially one of limbo. If you are on temporary basing then you just pay UK tax and that is the end of it. The figures given previously on this thread therefore all hold good.
Regarding permanent basing, at the current moment we use a system called the 'S690 scheme' for Italian-based crew which means that in effect you pay little or no UK tax. The good news is that you have a huge net take-home pay but the bad news is that the Italian government are going to want a lot of tax back very soon. As has been stated here, the Italians have higher tax than we do and therefore it is conceivable that you will take home less in Milan than you would do in the UK. The current easyJet line is that salaries are identical (gross) wherever you work but obviously if you pay more tax then you will actually get less money. I am assured that a 'day of reckoning' is going to come in Italy and our crew have been advised to be prepared for a substantial tax bill. At this moment no one knows exactly what that will be. The short answer is that the arrangements for Milan have not yet been finalised but you will be expected to pay any and all due tax. Not very helpful or specific but that is the deal.
