The pink ID worked for buying a motorbike. Lots of people think it is useless. Whatever. I was after the yellow book and the pink ID was immediately available so I got it.
I got a yellow house book in Sisaket province which can serve as a substitute for a foreigner residency certificate. Getting the yellow book was a bit of a process involving my Thai wife, her family, and the village headman. Once you get the yellow book you can, in the same office, get the Thai pink card which is what I am calling my Thai ID. It’s not exactly a substitute for your passport but it works in some situations like registering in a hotel or as an ID during police traffic stops.
CA noticed that I stopped paying taxes in 2019 and sent me a letter in 2023 saying they thought I owed them $6,000 in taxes. I sent them copies of my Thai drivers license, Thai ID, and a copy of my passport. They replied that they no longer considered me a tax resident. If you don’t live there you don’t owe taxes.
I am from California. My retirement savings are in Fidelity. When I changed my address to my Thai address there were no CA tax withholding on all of my withdrawals. I stopped paying taxes in CA two years after moving to Thailand. CA has acknowledged that I am no longer a tax resident. I am not a tax resident in any state.
