He claims to have done that to avoid taxes, however that isn't why people do that. Anything deposited over $10K in cash requires a CTR - Currency Transaction Report. It's basically a report detailing where the money is coming from. Tellers also have the ability to fill out a SAR - Suspicious Activity Report. Any time a cash deposit of $3K or more is made and is deemed suspicious by the bank, they must fill out a report about the funds.
right i know about the over so much filling the form BUT he sent the money through fedex without reporting it, he was probably doing it for the reason like you are saying but he also was doing it so he didnt have to pay taxes on it.
its got to be money he made through shady means that he didnt want to tell anyone about and paying taxes would have alerted someone.
like i said, the whole reason the govt has so many branches going after this is because they got shafted and didnt get their share. they'll spend a half mil to figure out why this guy didnt pay taxes on 150k
