Thanks Moses for your very thorough explanation and guidance.
There was talk about (rumor) where they would count the number of actual days spent in Thailand as displayed in your passport (for citizens of multiple countries [with multiple passports] - the one that has your Thailand visa) to determine the 183 days threshold and maybe tying that to your visa renewal with immigration - where if you exceeded the 183 days immigration may ask to see your Thai tax ID number and related Thai tax filings (if required).
In tax year 2023, I was outside of Thailand for 7 months for work reasons but I maintained a 12 month "residence" in Thailand - and I declared this as my bona-fide residence for purposes of determining my primary residence - as I had 2 residences in 2023 - but the other residence back in Europe was not "permanent" in nature as it was connected to my temporary work contract.
So, if in tax year 2025, I were to live in 3 different countries - but maintained a 12 month "residence" in one of these 3 countries (demonstrated by a 12 month rental agreement), wouldn't that country be my primary bona-fide residence - as it would also be linked to my 12 month visa in said country (with a right to stay as displayed on the visa) ?
