But it's not "everyone the same way". Thais do not have tax on earned interest automatically withheld from their bank accounts. We foreigners now do...and this just started automatically (on us only), regardless of amount earned, a few years back. As you are certainly aware, previously it was only after the earned interest threshold was reached.
Furthermore...my response was to the statement that the poster was concerned Thailand would start taxing money already here in the bank. They already do.
