Many people think they will have to pay no corporate tax when they incorporate in HK, if you want a real opinion about HK, you should ask people who have at least a 2 year old company.
I know someone who thought he would not pay any corporate tax, during the offshore profits claim, he has been asked to provide local tax receipt of his local tax authorities as he was not a tax resident, he could not provide it and had to pay the 15,6% corporate tax. Furthermore, he had to pay the HK company for doing the paperwork 2400 euros. In Total, it was like incorporating in the UK, where corporate tax is 20% because i can count the paperwork has a type of "tax". If we count the paperwork, local offshore company fees and tax, it was like 20% perhaps more.
