lol, I don't pay tax on anything I earn - I doubt that many people declare online earnings, I doubt the government really cares that much in anycase, how much does the average person earn online....
I have no Tax ID yet, so I think I shouldn't be worried much about that :p.
Oh, but well, generally, I don't think there's a mechanism to pay tax from online income in my country.
It's not fix/monthly salary, so the question is.. how?
To be honest I dont know how declare all my earning from online (in my country). However with all the taxes involve in buying anything at the shop, I can consider I've already paid for the taxes. Thats why most country had implement Service Tax (GST)
