IHT417 Form: Foreign Assets — Complete Guide 2026

What is IHT417 and when do I need it?

1IHT417 is the schedule submitted with IHT400 for assets the deceased owned outside the UK — foreign property, overseas bank accounts, foreign shares and business interests.
2It applies when the deceased was domiciled (or deemed domiciled) in the UK, because a UK-domiciled person is liable to inheritance tax on their worldwide assets.
3If the deceased was not UK-domiciled, their foreign assets are usually 'excluded property' and are not put on IHT417 — domicile is the deciding factor and can be complex.
4Value foreign assets in pounds sterling at the date of death, using the exchange rate at that date; up to 5% of the value can be deducted for the extra cost of administering or realising them abroad.
5If foreign death duties are also charged on the same asset, double taxation relief may reduce the UK inheritance tax.

Foreign assets trip up a lot of estates, because whether they belong on the IHT400 at all depends on the deceased's domicile — not their nationality or where they lived day to day. This guide explains when IHT417 is needed, what goes on it, and how to value and report overseas assets correctly.

When you need IHT417

Complete IHT417 (and submit it with the IHT400) if the deceased was UK-domiciled (or deemed domiciled) and owned any of the following outside the UK:

property or land abroad (a holiday home, an inherited family home);
foreign bank, building society or investment accounts;
shares in foreign companies, or foreign-held funds;
an overseas business or partnership interest.

Domicile is the deciding factor and is a complex area — if there is any doubt about whether the deceased was UK-domiciled, it is worth taking advice. See our guide to domicile and inheritance tax.

Valuing and reporting foreign assets

Convert to sterling: value each asset in pounds using the exchange rate at the date of death.
Deduct extra costs: you can deduct up to 5% of the value for the additional expense of administering or selling an asset abroad.
Double taxation relief: if the same asset is taxed both abroad and in the UK, relief may be available to avoid being taxed twice.
Moving money home: once the estate is settled, see transferring inheritance across borders.

Common mistakes

Assuming foreign assets are outside UK inheritance tax — for a UK-domiciled person, worldwide assets are in scope.
Confusing nationality or residence with domicile — it is domicile that decides whether IHT417 applies.
Using the current exchange rate rather than the date-of-death rate.
Overlooking double taxation relief and paying more UK tax than necessary.
