I have lived in Thailand for 20 years and fully declared my non-residency status to HMRC. In 2012 the HMRC told me I need not send an annual self assessment tax return each year anymore because I only have my UK pensions (taxed at source) and my bank interest which was very low and also taxed at source. However, my bank interest earnings (given gross- not taxed at source anymore) have shot up recently due to high UK bank interest rates, so I completed a questionnaire from HMRC as to whether I need to start sending then a self assessment for tax again, as I am registered for self assessment online. The questionnaire states that as I don't have income of more than £100,000 per annum income, nor any foreign income, and no more than £10,000 per annum earnings from bank interest etc then I don't need to send one.
I know I can ask HMRC directly but I want to put this to the forum first:
How come I wont have further tax liabilities this year if my untaxed bank interest has shot up?
Does the HMRC depend on other ways to find your income and then automatically send a self assessment to you if needed? The questionnaire is here:
