Split Year and Dispose of only oversea main residence

Having moved to the UK in July 2022, I sold my sole main residence in Hong Kong during this transition. The exchange of contract occurred before my move to the UK, with completion taking place after my arrival. Referring to RDRM12150, I understand that I may qualify for split-year treatment. My query is whether I need to include the capital gain in my self-assessment, considering that the exchange contract predated my arrival date.

Hi TomCambridge,
No, as you sold it prior to arrival and as your main residence no tax would be due.
Thank you,
