I see no reason to avoid paying income tax.
I have no choice regarding my tax liability, and my tax payment is therefore not voluntary but based on law and objective reasonableness. My salary is, by definition, Thai-sourced employment income, because I perform my remote work on Thai territory. This is a clear statement from a licensed and well-informed tax advisor. Whereby I have additionally cross-checked this statement with official sources.
It is the only right and lawful thing to do to pay my taxes here. As a guest in this country, it is particularly important for me to abide by the laws.
I therefore do not understand your comment on this. Just one comment earlier, you pointed out the tax obligation.
