Taxes pay for things like infrastructure, hospitals, defence and the like...In underdeveloped countries that may not have as many taxes those things are largely missing, uncared for or poorly maintained. But yes, taxes are excessive here in Australia.
Is staking reward and earnings from hive taxable as well ?
Yes.
If yes, how do you calculate and report them ?
With great difficulty. It's largely impossible to be honest. I guess they'll have to work out an average or worst-case scenario and work of that when they determine my tax bill. I'm sure I'll get fucked over.

I might, it depends how it all shakes out.
