HMRC have recently released annual statistical updates, one covering non-UK domiciled taxpayers and another covering Inheritance Tax (IHT) and associated reliefs. We summarise some of the key and interesting figures.

  • Non-domiciled taxpayers paid £7.896bn in Income Tax, Capital Gains Tax (CGT) and National Insurance Contributions in 2020-21 and £7.878bn in 2019-20.
  • It is estimated that at least 10,100 individuals were Deemed UK domiciled in 2020-21, under the new rules introduced in 2017.
  • In 2019-20 (the most recent year for which such data is available), of the 62,900 UK resident, non-domiciled individuals, 44,400 claimed the Remittance basis. The remaining 18,500 were taxed on the arising basis.
