According to the Daily Express ...
It seems that a new Inheritance Tax loophole has opened up which can help people avoid losing 40 percent of the value of their estate.

In her recent Budget, the Chancellor targeted tax certain loopholes (with the change in farmers Inheritance Tax liability proving particularly controversial). However, one change - regarding “non-dom” status - could actually help some people avoid paying this IHT on their estate.

"Wealthy Brits" retiring overseas can avoid paying IHT on their foreign assets - just so long as they follow the '10 year rule' which is being introduced.

Currently, anyone with a British 'domicile' will be liable to pay Inheritance Tax on their worldwide assets - even if they spend their retirement abroad (such as moving to Spain).
But if you have lived outside the UK for at least 10 years, then you may not be liable to pay the 40 percent Inheritance Tax on your estate's assets.

In the new system, your “domicile status” is being replaced with a “residency status” – and thousands of expats may potentially benefit from this after April 2025, as it broadly means those resident in another country for 10 years before they die won't be liable for any Inheritance Tax on their overseas assets in their estate.

Expert tax firm BDO outlined the changes, saying "The new rules will apply to Inheritance Tax on chargeable events occurring on or after 6 April 2025.
The test for whether overseas assets are within the scope of UK IHT will be whether a person has been a UK resident for any part of the 10 ‘tax years’ prior to the year of the chargeable event. If you meet this 10-year test, you remain within the UK IHT net for the next 10 years, regardless of whether you’re resident in the UK or not. Individuals will need to be non-UK tax resident ‘for at least 10 years after leaving the UK’ to be outside the scope of the UK's Inheritance Tax."
An HM Treasury spokesperson said: "Replacing the outdated 'non-dom' tax regime with a new internationally competitive residence-based system addresses unfairness in our tax system."
