I was told by my KBank bank manager a few years ago that anything over 10,000 usd equivalent can be more subject to scrutiny re money laundering etc,, I’ve sent regularly monthly and try keep below that value, I’ve never had an issue, I have also on one occasion sent above that value no issue although took a couple days longer than normal to arrive
duration to arrive also depends on how much is sent, send 20,000thb it’ll arrive in seconds, send 450,000thb it can take a few days, this is certainly the case with my revolut account anyway
to further complicate my situation, I stay here this as my permanent home with my wife, yet I’m always less than 180 days in country, I haven’t lived or been in my home country for over 5 years, nor have I stayed in any other country over 180 days, been same status as this for years,,, 🤔
I’m not sure about being taxed, but amounts over 10,000 usd in value are more likely to come under investigation, I’m not suggesting anything untoward in anyone’s transactions, but they may be delayed due to investigation, this I was told years ago by the manager in my KBank branch.
