"Where Thai domestic law is still silent about a foreign tax credit available for individual taxpayers under this circumstance, a provision under double tax treaties could provide relief from any double tax arising. However, the conditions, methodologies, and documents supporting the claim are still unclear."
Having lived in Thailand for 26 years I am somewhat cautious whenever I hear about something that is presented as a done deal.
I have had two situations when I tried to withdraw money from an ATM in Thailand and nothing came out, but the money was still debited from my account. The first was maybe 3 years ago when I try to withdraw 10K baht. No money, but I got a notification on the banking app on my phone that the money had being taken out of my account. But after about 10 minutes I got another notification that showed 10K going back into the account. So there was obviously some kind of error that was corrected. The last time was about 3 weeks ago when again I tried to take money out of an ATM but nothing came out. The account was debited but this time it didn't correct the error so I had to call the bank and they said they would investigate. After a couple of days I got a call from the bank saying there had been a mistake and they credited my account. I don't know what would have happened if I hadn't contacted the bank or whether the error would have been eventually corrected. All the ATMs are connected to a network so they send the data back from the machines to the bank's computer system which reconciles all the transactions and checks for any errors.
