If you living in Thailand for 180 days or more in a calendar year and you transfer (remit) in more than THB120,000 (or THB220,000 for married couples) per year of foreign-sourced income from outside Thailand, you’ll need to file a tax return for 2024.
This includes UK pensions. You can use any tax you have paid as credit against tax owed in Thailand, but it doesn’t mean you don’t have to file and you may have further tax to pay.
