Thanks for the input guys.
The thing my country has tax-agreements with HKG and so if I would to stay more than 183 days outside of my homecountry for work purposes I won't have any problems at all.
Ok that's life and I have to live with it. But what I do find strage is this whole tax thing, because I will NEVER register myself in the UK. I just want to fly there, pick up the airplane and leave, maybe the same day or maybe the next day, THAT's IT. How can they still be making a big deal out of me paying any taxes in the UK, it's just a base, I come and go.
But what I still wonder is what the UK resident Cx pilots think about this. Doesn't the tax man have ANY mercy????? And what do you guys expect Cx will do about this Tax situation??
