Date of Arrival computation for Split Year taxes

HI. My wife and I plan to move to the UK during 2024. I would like to know how "date of arrival" is computed. We plan to finish with my current employment in the US and sell our US home by 15 June, and travel to the UK on 16 June. However, we may travel to the UK in May for 10 days to visit my wife's parents and look for a new home. We have not lived in the UK in the previous 10 years. What would be our "date of arrival" for split tax year purposes? The purpose of this question is to ensure the capital gains on the sale of our US home are NOT included in the UK portion of the split year (our situation is MUCH more advantageous under US tax law). Thanks for your time.

Hi Richard Armstrong,
HMRC cannot advise on future events as legislation may change. residence is also for you to determine based on the guidance available.
