I recently received a message on my Halifax UK banking app asking me to confirm my tax residency.
The residency drop-down box was locked to Thailand, probably because I spent 7 months here last year, and I had to input my TIN or it wouldn't let me progress. Luckily, I had one from when I worked here many years ago and it was accepted.
I find it strange that the residency was locked to Thailand as I'd previously worked for 6 years in China (and my app is registered to my Chinese mobile number) up until end of March 2024, then 7 months here as a tourist and then 6 months back in the UK.
There's no info on my SCB app to date and they didn't mention anything when I went to the bank to update my passport recently.
Curious 🤔
