Moving Abroad and Inheritance Tax Planning

Apr 8, 2026

For a growing number of UK property owners and landlords, rising property values and frozen tax thresholds mean Inheritance Tax (IHT) is no longer a problem only for the very wealthy. Frozen thresholds combined with rising asset values are pulling more estates into the IHT net. As a single person, the Nil Rate Band is £325,000, frozen until April 2030. There is an additional Residence Nil Rate Band of £175,000, which applies when passing on a main residence to direct descendants, potentially raising the threshold to £500,000. Married couples can pass on unused allowances, allowing for a combined threshold of up to £1m.

Clients are therefore increasingly asking whether moving abroad could reduce their exposure to UK IHT. So, should a long‑term UK resident consider a move abroad as part of their IHT planning? We break the key points down in plain English, with a focus on what actually matters for UK landlords and property investors.

If I move abroad, does it automatically reduce UK Inheritance Tax?

In short: no, not straight away.

Under UK rules, if you are classed as a long‑term UK resident, you remain within the scope of UK IHT on your worldwide assets, even if you move overseas.

You are generally treated as a long‑term UK resident if you have been UK tax resident for at least 10 out of the previous 20 tax years. This is a common issue for landlords who have spent most of their working lives in the UK building property portfolios, often alongside Family Investment Companies (FICs).

Why Timing Matters – The IHT Tail

It is worth noting that after you move abroad, you may still be caught by UK IHT for between 3 and 10 tax years, depending on how long you lived in the UK beforehand.

Double Tax Treaties – Do They Help?

Double Taxation Treaties can be useful potentially – but only in specific circumstances. Much depends on the focus of on domicile under common law rather than tax residence with each country.

What are the Implications for Property Owners

UK property will always remain within the scope of UK IHT. Some gifting strategies can still trigger gifts with reservation rules. Moving abroad does not automatically remove UK IHT exposure. UK property remains subject to UK IHT regardless of where you live.
