incorrect. If you are tax resident in 2024 and you remit income earned in 2024 in 2025 and you are still a tax resident in 2025 then the remittance is taxable. Thailand taxes foreign income earned whilst tax resident even if remitted in future years (as long as you are tax resident).
Anonymous participant unless you become a snowbird your UK pension will be frozen if you chose to retire in Thailand. You relinquish UK tax residency over time through your physical presence in Thailand.
agree, moving funds into Thailand whether electronically or physically is bringing funds into Thailand but not every remittance is taxable. Only assessable income remitted whilst tax resident is taxable.
