In 2022 I stayed over 180 days in Thailand. I did not work in Thailand. I have funds/savings in Europe and make transfers to my Thai Bank account. I requested for a Tax Identification number but the officer asked me to show my bankbook and want to tax me over the funds I transferred to my Thai account during 2022. (less the official deductions).
For as far as I know I only have to pay over income that I received in Europe and transferred to Thailand, and not over savings. Am I correct?
