This is my problem, I've been to the tax office 4 times each time thay have said "you don't need to pay tax"
Told them what I bring in 2 government pensions (according to Google both can only be taxed once,London Fire Brigade, UK State pension) I pay tax on them in the UK, tax office also agreed that thay can not be taxed here, 3rd pension is from Tesco 1,800 bht per month so not enough for tax to be paid.
