The Chancellor announced a number of important changes to the tax treatment of individuals who are resident but not domiciled in the UK. Such individuals currently benefit from a number of tax advantages such as exemption from UK inheritance tax (IHT) on assets situated outside the UK and in some cases only being taxed on overseas income and gains if those amounts are remitted to the UK.

From April 2017, IHT will be payable on all UK residential property owned by non-domiciles, regardless of their residence status for tax purposes, including property held indirectly through an offshore structure.

From April 2017, individuals who are born in the UK to parents who are domiciled here, will no longer be able to claim non-domicile status whilst they are resident in the UK.

The government will also legislate so that from April 2017 anybody who has been resident in the UK for more than 15 of the past 20 tax years will be deemed to be domiciled in the UK for all tax purposes. This is being reduced from the current 17 year deemed domicile rule for IHT.
