A spicy headline certainly doesn't hurt with the number of views!
But techically speaking, if you moving funds into a different format to evade taxation, then you are in fact giving those funds a light rinse -if not a full-on laundering.
Likewise, to my expat friends, if you are charging a pair of jeans at the Gap on your USA-based VISA card, that is viewed by Inland Revinue as an "in-kind remittance" and strictly speaking should be listed on your tax return as remitted income. If you receive any cash or in-kind benifet, it is taxable over here at the standard rates. If you did not, then you too have evaded taxation illegally.
The poetry of inland revinue says that you may AVOID taxation, but you may not EVADE taxation.
And they will decide which is which, by the way.
