I have checked that I fulfill the split year requirement. I arrived at UK on 1/1/2023 and I have the following enquiries: (1) I sold two flats BEFORE arriving in UK . One is self-living and another is for renting out. Both transactions have been completed before I arrive in UK. Do I need to report these two transactions for the split year? If yes, may I know which form should I fill in? (2) I have started a 1-year fixed rate saving deposit from 1/8/2022 to 31/7/2023. The interest will be paid on 31/7/2023. I understand I need to report the interest in the tax year when I receive the interest. So, I think I do not need to report it this year. Am I right? I will report the interest (say GBP10000) I have earned in NEXT tax year as I will receive the interest on 31/7/2023. But I am not sure whether I can only report the interest which belongs to the part after I arrive at UK on 1/1/2023 (i.e. GBP 10000 X 7 months /12 months)? Many thanks
