Yeah this is a really interesting point for me.
The recent change to the tax regulation was that all money remitted to Thailand is liable for tax, where as previously it was only liable if it was earned in the current year it was remitted.
In the past, how many of us, or people we know, or even people we have heard about, have been audited by the Tax man to prove money remitted wasn't earned in the current year? I'm going to guess not many of us.
