An inheritance tax (IHT) regime based on residence rather than domicile was announced by the previous Government in its Spring Budgetopens in a new tab of March 2024. One year and 30 days later, the new regime will be effective from 6 April 2025. Its detail has been decided upon by the current Government (different from the one which announced it) without the consultation originally promised. At the time of writing Finance Bill 2024-25, which contains that detail, is in its final form and is pending Royal Assent.
In some ways the residence-based regime will be simpler and clearer cut than the rules based on domicile with which many are familiar. Since April 2013, residence has been prescribed by the detailed rules of the Statutory Residence Test (SRT). In contrast, the law around domicile is governed by voluminous case law and is very fact specific, with some recent cases being found in favour of the taxpayer and others in favour of HMRC. The new regime will remove the subjectivity of domicile and provide more certainty for all. There are, however, a number of aspects buried in the legislative detail which may catch some unawares.
At its simplest, the residence-based concept is straightforward enough. Anyone who is a ‘long-term UK resident’ (LTUKR) will be subject to IHT on their worldwide assets on death or on the making of certain lifetime gifts. Anyone who is not a LTUKR will only be subject to IHT on their UK assets; their non-UK assets (except for those whose value represents the value of UK residential property, which are deemed UK assets for IHT) will be outside the scope of IHT.
