Why are you do keen to report it,,,?
If my missus transfers 20,000 Baht to me, do you expect me to report it?
If my mate Geoff transfers 30k to me to repay the money I lent him last week to make up the purchase price for a new TV, do you want that reported as well.
Get a grip! The Thai authorities can't handle genuine remittances, let alone transfers between individuals.
