1,552,640.00 may be the most exact approximation I have seen in some time
My experience of the Hong Kong Immigration department, of whom I am a considerable fan, is quite simple.
For conditional residency, if you are a good prospect for paying tax (especially in considerable amounts) you should have little to worry about and a professional organisation like Emigra (with whom I personally have had no dealing) should not be struggling to make a case.
Only an insignificant minority of Hong Kong residents pay tax in Hong Kong. If you threaten to join those ranks and even worse might employ someone then there will be a way forward for you. I have a friend who approves PR applications - I once had a very enlightening conversation with him in Lan Kwai Fong.
That is not an official policy though.
