CGT due on main residence as a non-UK resident

Hello HMRC, I am UK tax resident who is planning on leaving the UK to live and work abroad. My intention is to claim split year treatment once I do so, therefore I understand I will be treated as a non-UK resident for tax purposes. As part of my move, my wife and I will be selling what has been our main residence since we bought it in 2020, however we will only be able to sell it once we moved abroad and will therefore be classed as non-UK residents. I have a few questions: 1. Would I need to pay Capital Gains Tax on the sale? 2. I understand I need to notify HMRC within 60 days of the disposal date, and also fill in the appropriate section within the self assessment. Do I need to do it irrespective of whether or not CGT is due? Thank you in advance

Hi

There may be some to pay dependoing on how long it takes to sell as you will due a further 9 months after leaving the property to claim private residence relief.
As non resident you need to declare the sale even if no tax is due.

Thank you
