since when did hong kong tax drop to 10% ??? you'll pay 16% hong kong tax, however depending on your DOJ you won't get a bill for 18-24 months...................UK Taxman is talking to CX at the moment thanks to the 49'r court case and they may well have to introduce PAYE in the next 2 years. France is apparently ok as long as you show them you are paying HK tax ...............................
Basing may well not be your choice ....................anyway the first 4-5 months will be in Hong Kong................enjoy the stay at the Headland and the CX Checking system..........................
