>>507084810 (OP)Braindead retard explanation: Open a business where it's impossible to know how much money comes in.
T-Shirts?
You can charge whatever you want for a custom design.
Pizza? Who knows how much a pie costs in labor or ingredients?
Bullshit knives? You're charging random mall ninjas random amounts.
That makes it easy to give the tax man a random number and then pay taxes on that.
The dirty secret of money laundering is that they aren't THAT interested in where it comes from. They just want to skim off their share.
