Split Year - start date for the UK part

Dear HMRC staff, My family and I moved from Hong Kong and live in the UK through BNO 5+1 visa on 9 Aug 2022. Having stayed in the UK for more than 183 days, I believe I am the resident starting from the tax year 2022-2023. Before 9 Aug 2022, I did not have other ties (I had no home, no any income and no family tie in the UK). We lived in a temporary Airbnb from 9 to 14 Aug 2022 before moving to a leased house on 14 Aug 2022, leasing agreement started on 12 Aug 2022. I still own a flat in Hong Kong, which is my original residence, even I have arrived in the UK. From my understanding, split year case 4 or case 8 are likely to be applied for my situation, when the tax year for the UK part start from? 9 Aug, 12 Aug or 14 Aug 2022? Many thank for your reply! With regards, CC

Dear HMRC staff, Would you please help to reply my inquiry. One more question, is split year case 4 or case 8 applied to me? Thank you very much. With regards, CC

Hi CC Chan,
It will apply from 14/8/22.
Thank you. 

Thank you. Based on my case, which case of split year apply to me? case 4 or case 8? Many thanks! With regards, CC

Hi,

We are unable to advise whether split year treatment case 4 or 8 applies to you. This is something that you will need to determine for yourself.  

Thank you.
