I am an accountant by training, but dont work as one, but I know a lot of good accountants! Residency is a big big taxation subject and it is no surprise that there is no 'residency' definition in EASA land. For a fee, I can find a lot of USA companies who can be the registered operator of my N reg aircraft......but how do I know if I as the pilot am an EASA resident? Is it the tax definition, time spent, citizenship, domicile, parenthood??????
