Hello, I am doing my tax return in one of the programmes for filing returns. This tax year it has been 7 years I have been on non-dom remittance basis taxation. I answered "yes" to "were you resident for this tax year and 7 or more of the preceding 9 tax years". I have nominated some income in relevant boxes. Yet the programme doesn't suppose I have to pay remittance base surcharge of 30k for this tax year. What would you advise, should I just send additional 30k payment to Hmrc?
