Yes, went to local tax office, on Samui, with pink ID and passport in 2024, told them I needed TIN number to file tax return in 2025, TIN issued. ( OA retirement visa ).
Tomorrow's buddha day is also an election day on Samui so any new rules will only apply after 1700 till midnight on Sunday, therefore still no alcohol 1700 Saturday till 1700 Sunday.
On Samui you only needed home license and IDP for initial 2 year license. For 5 year license all other documents required as above. Don't know about qr code as it didn't exist when I last renewed 5 years ago.
