Don’t Leave without Saying Bye: Leaving the UK and Split-Year Treatment

What is Split-Year Treatment?
According to migration statistics in a Commons Library briefing paper published in May 2022, in the year ending June 2021, 334,000 people emigrated from the UK. When leaving the UK, careful consideration should be given to the Statutory Residence Tests (“SRT”). Under these tests, an individual will either be UK resident or non-UK resident for the tax year.
We have previously written a blog on the SRT which can be found here.
However, where an individual decides to leave or arrive in the UK during a particular tax year and meets the relevant conditions, their tax year will be split into two parts (which can have a number of crucial tax consequences):
- The UK element where they will be taxed as a UK resident; and
- An overseas element where they will be taxed as non-UK resident.
- Be UK resident in the current tax year.
- Be resident in the UK for the previous tax year (whether or not it was a split year) (i.e. the 2021/22 tax year as we are currently in the 2022/23 tax year).
- Be non-UK resident in the following tax year by meeting the third automatic residence test (i.e. 2023/24 tax year as we are currently in the 2022/23 tax year).
- Be able to satisfy all of the ‘overseas work criteria’ from the day they start working overseas to the end of the relevant tax year.
- Be UK resident in the current tax year.
- Be resident in the UK for the previous tax year.
- Have a partner whose circumstances fall within Case 1 for the current tax year or previous tax year.
- They have both been ‘living together’ in the UK in the current tax year or previous tax year.
- During the relevant tax year, leave the UK to live with their partner whilst the partner works overseas.
- Be non-UK resident for the tax year following the tax year of departure.
- From the date of departure, the taxpayer has no home in the UK at any time or has homes in both the UK and overseas but spends the greater part of time in the overseas home.
- Any days spent in the UK following departure are within the “permitted limit”.
- Be UK resident in the current tax year.
- Be resident in the UK for the previous tax year (whether or not it was a split year).
- At the beginning of the relevant tax year have one or more homes in the UK and there is a day in the relevant tax year where they cease to have a home in the UK and not have one for the remainder of the tax year.
- Be non-UK resident in the following tax year.
- Spend fewer than the necessary limits set out in legislation in the UK.
- Within 6 months of ceasing to have a home in the UK, the individual needs to have a ‘sufficient link’ with the country overseas. This sufficient link could include becoming resident for tax purposes in that particular country or be present in the country at the end of each day for a 6-month period after ceasing to have a home in the UK.
