I have just a couple of questions and one is regarding the provisional tax. Is it just extra tax like council tax?
Is crwjerk's case of possibly paying $18000 tax a month typical?
No its not extra tax. It is advance tax for the next year. You may not have to pay it, depending when you start working in HK. If you do your following year's tax will be correspondingly lower.
HK$1,000 for phone is also way to much. You can get combined Internet, Phone and Cable TV packages for much less.
Utilities should also be much less.
There's lots of info available on-line, its better if you do your own research.
