In South America, tax evasion has evolved so much that there are software packages with built-in "under the table" accounting, and dual accounting (one for the state and the real one).

Paying actual taxes is a fast way to bankruptcy here :( , the above-board companies look for tax loops, smaller ones make do with dual-accounting and understating income.

Government figured out that income tax is the most difficult to fake and heavily hammers employees :(
