In the last few weeks I’ve noticed a delay in Wise to Bangkok Bank transfers also, generally for larger amounts though. I transferred 100k yesterday and it took about 12 hours. Transferred 650k a few weeks ago and it took about a week to clear.
Just wait it out. Personally, if I was in tax resident status and not actually earning money here I wouldn’t get a TIN or file anything until I was forced to. These changes are for catching high net worth individuals who are evading taxes, not your average expat.
If the money is hitting your Thai bank account and you are here longer than 180 days then you are obligated to report it. That doesn’t mean you have to pay taxes on it though. Best to ask a tax professional though.
Be aware that local banks will likely start reporting significant money transfers soon to tax authorities to bring them in line with international standards. There is a huge push now to crack down on money laundering and to a lesser extent tax evasion. Pieces are being put in place to automatically identify violators in the near future.
