L2021

Hi I become UK tax resident in July 2021. I have gained saving interests and dividends during the tax year and no more further other income in UK. 1. The total amount of saving interests is less than the starting rate £5,000, do I need to report this? If so, which form should I fill in to report? 2.If the total amount of dividend (i.e. £1,000) is less than dividend allowance £2,000, do I need to report this? If so, which form should I fill in to report? 3. If the total amount of dividend (i.e £5,000) is more than dividend allowance £2,000, can I use the personal allowance £12,570 to deduct the rest of dividend (i.e. £12,670-£3,000)? Thank you!

Hi, I became a UK tax resident in July 2021. I have sold some shares gaining £3,000 between Oct 2021 and April 2022. In this case, the gaining £3,000 is less than the Capital Gains Tax Free Allowance £12,300. Do I still need to report the capital gaining £3,000 and filing the SA108 Form if I will apply the split year treatment for the tax 21/22? Thank you!
