UK Property Sales by Non-Residents: Capital Gains Tax Explained
Individuals who are not UK tax resident and are disposing of UK land or property, including overseas landlords and non-UK based owners. The Non-Resident Capital Gains Tax (NRCGT) reporting requirements, the 60-day filing obligation, and how gains are calculated for non-residents. Non-residents must file a return within 60 days of completion — even if no tax is payable. Failure to comply can result in penalties and interest.When Non-Resident Capital Gains Tax Applies
Non-UK residents disposing of UK land or property may be subject to Non-Resident Capital Gains Tax (NRCGT). Only the amount of the overall gain relating to the period after 5 April 2015 is chargeable to tax. This reflects the introduction of NRCGT for non-residents disposing of UK residential property.2015 Position
- Gains arising before 5 April 2015 are not chargeable under NRCGT.
- Only the post-5 April 2015 portion of the gain is within scope.
2019 Extension
- The regime was extended to include non-residential property from 6 April 2019.
- This broadened the scope beyond residential property.
Reporting Alignment From 2020
- Since 6 April 2020, non-residents have needed to report disposals and pay tax within 60 days of completion.
Mandatory 60-Day Reporting
A return must be submitted within 60 days of completion. The return must be made whether or not there is any NRCGT to be paid. This is a statutory reporting requirement.How the Gain Is Calculated
- Calculate the total gain on disposal.
- Identify the portion of the gain relating to the period after 5 April 2015.
- Apply any available reliefs where applicable.
