Non-UK Domicile? What It Really Means for IHT

By WePlan.Money

Your "domicile of origin" can trump where you live when HMRC calculates inheritance tax.

Domicile vs. residence vs. deemed-dom

You can be UK resident for 20 years yet remain non-dom for IHT until you hit the 15/20 deemed-dom threshold.

Planning levers

  • Use excluded property trusts before becoming deemed-dom.
  • Hold overseas property through non-UK companies.
  • Split-year treatment when leaving the UK for good.

Common mistakes

Owning UK-situs assets through an offshore company no longer protects against IHT (post-2017 rules on "enveloped dwellings").
