Something to Gain – Capital Gains Tax for Non-UK Tax Residents and UK Property

Non-UK tax residents are generally not liable to capital gains tax (CGT) in the UK, on the disposal of assets. However, there are exceptions to this, in particular capital gains on UK based land/property and the rules applying to temporary non residents.
This is especially relevant for taxpayers who leave the UK and become non-UK tax resident, as they may not be aware of their UK tax and compliance obligations.
Non-UK Residents and Capital Gains on UK Property
As noted above, individuals are generally not liable to CGT on capital gains when they are non-UK tax resident. However, where the gain arises on land/property based in the UK, then the gain is subject to UK tax.
The rules also extend to assets that derive at least 75% of their value from UK land (such as shares in a company that owns UK property/land). This could extend to 'property-rich' companies.
Up to 5 April 2020, the gain was reported on a Non Resident Capital Gains Tax return. From 6 April 2020, relevant gains are reported via the Capital Gains Tax on UK property service.
The gain will need to be reported (and tax paid where relevant) within 60 days of completion of conveyance (prior to 27 October 2021, this deadline was 30 days).
Method of Calculation
The CGT calculation requires you to consider the gain on the property:
- from 6 April 2015 for UK residential property (where it was owned on/before this date); and
- from 6 April 2019 for UK non-residential property, and indirect gains on UK property, where the assets was owned on/before this date).
- the individual becomes non-resident;
- the individual was UK resident for at least 4 of the 7 tax years immediately preceding the year of departure; and
- the period of non-residence is 5 years or less.
