I wouldn't be overly concerned about it. Unless you're bringing in large sums of UNTAXED income, the tax authorities in Thailand know you've already paid in another country, and provided you're only bringing in essentially "money to live on" it's not worth their while to go hunting the small amounts of differences. This law has always been in place, but it's just not economical for them to go auditing every foreigner living in Thailand!
Probably because the authorities know all about fake marriages so they make the requirements more arduous. If I was stupid enough to get married in Thailand, I'd still stick with the DTV
It's nothing to do with savings! It's INCOME earned prior to Jan 1st 2024 which is exempt. You need to stop watching these YouTube videos! I stopped "working" in 2014, so no more "income" for me (not in my name anyway!) 😂😂😂
