What do you do if you're a high profile criminal with state-level enemies and can't file tax returns under your real name and address? Can you ask IRS to send you a tax return via a mediator accounting firm (an outlaw entity with headquarters on ships in international waters)?
The money laundering conviction requires that the state has proven that the source of money was illicit, successful money laundering only has an indistinguishably licit source. Basically the stigma on simply having a lot of money moving around isn't based in any legal reality. The state has to prove what the source is, that the source was illegal, and then that you are obfuscating the source, in order to prove money laundering, but not a tax evasion conviction. An obfuscated but legal source would not be money laundering, it would be business expenses and compliantly paid taxes.
You don't file taxes on stuff you steal or earn from illegal means, if you do that means you missed a step and incriminated your criminal activities that earn you the funds all to avoid a tax evasion conviction. You pay taxes on the converted money that looks no different from employment or tech sales.
(or like the other person said, not paying taxes at all and keeping a low profile, but I don't agree with that, the goal is to mitigate all technical liability)
