As is mine. But those claiming the new State Pension between now and 5 April 2026 will receive a weekly payment of £230.25*, which, by my reckoning, converts to around 525k THB per annum on the basis of current GBP:THB exchange rates. Since this is in excess of the various TRD allowances and exemptions which potentially total 500k THB in the case of those eligible for the State Pension, it follows that they might actually have to pay tax locally in respect of their State Pension income which was fully remitted on a calendar year basis - subject to prevailing GBP:THB exchange rates, of course.
Strikes me that those who are already in receipt of a frozen new (as distinct from basic) State Pension and are clamouring for this to be increased to current triple-lock rates in their cases may need to be careful of what they wish for!
