IHTM47070 - Long-term UK residence test: Introduction to Double Taxation Conventions

From 6 April 2025 a person’s UK Inheritance Tax position will depend on whether they are a long-term UK residentÌý(IHTM47000).Ìý

A double taxation convention between the UK and a foreign country may apply if a person is in scope for UK Inheritance TaxÌýor its equivalent in the convention country. The UK currently has 10 double taxation conventions in placeÌýwhich have been negotiated between the fiscal authority in each country. (IHTM27161).Ìý

A double taxation convention seeks to eliminateÌýdouble taxation by assigning taxing rights to one country or the other and,Ìýon occasions where both countries retainÌýtheir right to tax the same assets,ÌýitÌýdeterminesÌýwhich country will allow and apply a credit.ÌýÌý

Where primary taxing rights cannotÌýbe established,Ìýa tiebreaker set out within the convention will be applied.ÌýÌý

Each convention variesÌýin itsÌýapproach to eliminatingÌýdouble taxation and some only applyÌýin respect of duty or taxes imposed on death whilst others also applyÌýfor charges imposedÌýonÌýother occasionsÌýi.e.Ìýlifetime transfers.ÌýÌý

From 6 April 2025, where a double tax convention operatesÌýby reference to whether the UK treats a person as UK domiciled for Inheritance Tax purposes (deemedÌýdomicile), a person will be treated as UK domiciled if they are aÌýlong-term UK resident.ÌýDeemed domicile is relevant to some of the double taxÌýconventionsÌý(IHTM47071) but not others (IHTM47072).Ìý

However, where a person is treated as domiciledÌýor long-term residentÌýin the UK for the purposes of Inheritance Tax because they haveÌýmade aÌýspousal domicileÌýelection (IHTM13040) or a long-termÌýUK residence election (IHTM47031)Ìýthis will be disregarded in applying any of the existing double tax conventions.Ìý(IHTA84/267ZF(3) and (4))Ìý
