Drug dealers don't file tax returns? Okay, estimate their income, send a bill, and follow up with armed raids to collect. Coyotes don't file tax returns? Okay, every time a truck full of illegals get apprehended at or near the border, seize whatever assets the driver has until he talks about where his boss can be found. And then confiscate assets from the next level up. Rinse and repeat.
Drug profits are income. Al Capone went to prison for tax evasion. Learn from history and repeat it.

Clearly you do not understand how modern money laundering works.
