I'd first and foremost try to avoid it. How non-ideal are we talking?
If you've been engaged in serious criminal activities (drugs, hacking, weapons, trafficking, terrorism), you have a big problem.
But if the funds are less gravely tainted, then you might be surprised how lenient tax authorities can be if you proactively negotiate with them (with the help of a lawyer). You might end up paying more tax than you would've in an ideal situation but that's probably less of a bother than the prison time you're facing if your laundering scheme blows up.
Relocation to a place with low taxes and/or fewer questions for a couple of years while you cash out might also be a worthwhile endeavor.
