If you refuse to pay the tax, will they throw you out of the country?
I was leaving Hong Kong once before the turnover and my visa expired at midnight. I was going through customs to leave at about 11. Because my flight was at 12:05 they pulled me aside and said I was overstaying my visa.
I said ‘wait, I’m trying to leave’ are you going to put me in jail for trying to comply? They ended up fining me something like $50 to let me make my flight...
but no they won’t just throw you out - they’ll detain, possibly put you in jail, fine you, ....and then throw you out.
I was always worried I got on someone’s list after that, but never had any issues when I went back before and after turnover.
