The problem with businesses is that they hide systematically profits. The big ones are shifting their profits globally. The small ones never register profits (claiming they always operate at a loss, specially if they operate with mostly cash and not credit cards).
And in business, it is easier to hide your profits because you can shift around money to assets (this ferrari and the Manhattan condo are company owned), compensation (my CEO will get a 1000% raise this year), liabilities (paid off that huge loan we got to buy the lambo) etc.
The problem cannot be solved unfortunately. There are crude methods like estimating profits from revenues, but really, this has never worked.
It depends. In my country there are examples of employers who were paying extra their employees (who were not taxed due to their pity salaries) and were requiring them to return part of their salary as cash.
