What makes it tax free? My tax form (and I expect most other countries too). Have a box for "Other income - including tips, cash payments and profits of illegal enterprise"
Now I realise that many may not bother to pay, but that isn't quite the same as tax free.... is it? In any case in some parts the wrath of The Revenue is worse, and harder to avoid than the local law enforcement.
