Taxation of Tax Residents - look at the video 3:15.

Interesting 3 points made.

Some very good info in here I had not heard before. One thing that was new to me is banks report to revenue all accounts with over 2 million THB in or 400+ transactions a year.

Bottom line for DTV holders - unless you are remitting large amounts of money you earned in the same tax year you are tax resident then do not worry so much about tax.

EDIT: Around 30 mins they clear up ATM and CC use - yes it counts as remmitance
