The fact that there is a DTA with UK, does this mean any income I'm taxed on in the UK, eg. Pension, Rent, interest , dividends etc, is exempt from taxation in Thailand ? I understand that the tax free UK personal allowance is taxable in Thailand and 25% pension lump sum is also taxable. I also know tax credits can also be used.
I'm in UK now going through redundancy, and the plan was to move over in the next couple of months. I have no problem in getting a tax ID, however, if Thailand tax's me on income I've already been taxed on, I'm seriously reconsidering my move...
