I don't think so. Money laundering is hiding the source of the money, usually because it's illicit.

This might be tax evasion if you hide it from the IRS, but that's not laundering.

IANAL, of course.

Wikipedia's article on money laundering states that in some countries obfuscating the sources of money is considered money laundering. This means that at least in some countries this fits precisely the definition of money laundering.

A drug dealer tumbling ether _is_ hiding the source of the money.
