Basically if you are getting money from somewhere even an ATM it's accountable. I can see if you have multiple bases or layering it's doable but not everyone can do this unfortunately.
Read again, please , and make sure to distinguish between remitted MONEY and remitted INCOME.
If you are a tax resident in Thailand but have an existing net worth (principal, savings, etc.) that was accumulated before becoming tax resident, then this money can be remitted into Thailand tax-free, as it is NOT considered foreign income.
If, on the other hand, you didn’t have significant net worth prior to moving to Thailand and you're now living off your current income, then yes , the situation becomes more complicated.
However, even in that case, you can still choose to stay in Thailand for fewer than 180 days in a calendar year. This way, you are not considered a tax resident for that year, and you can remit funds (even for one or two years or more) without triggering taxation.
We’ve discussed these topics many times with @wellington , please double-check using the search function.
In any case, if Thailand confirms this new rule , where remitted income earned during the current year or the following one is tax-exempt , it would likely resolve 99% of the situations faced by ‘normal’ farangs living here.
