I purchased a property in the UK along with my sister in September 1997. My share of the purchase price was £45,000. It was sold on 19 February 2021 and my share of the gain was £45,500. I have not been a resident of the UK since November 1999 (having lived at the property for just over two years). I am currently a permanent resident of the USA. How do I report and calculate my tax liability to HMRC? 

Arthur Weller replies:  

Since you are currently not a UK tax resident, and have been a non-UK tax resident since 1999, you are also not a ‘temporary non UK tax resident’ as per HMRC’s Residence, Domicile and Remittance Basis manual at RDRM12600. Your CGT liability on the sale of this UK property is limited to the increase in value of the property from April 2015, until the sale. You need to report the sale to HMRC; see HMRC’s Capital Gains Tax for Non-Residents’ for UK property and ‘How to report disposals’.
