Guernsey is a Crown Dependency with its own independent legal and tax system. It does not levy inheritance tax, estate duty, wealth tax, or a general gift tax, making it an attractive jurisdiction for internationally mobile individuals and high-net-worth families.
However, moving to Guernsey or holding assets there does not automatically remove exposure to UK inheritance tax (IHT). Under the UK’s long-term residence (LTR) regime, your worldwide estate may remain within the scope of UK IHT after you leave the UK, depending on your residence history.
This article explains Guernsey’s tax framework, probate and succession rules, and how the UK LTR regime affects inheritance tax planning for individuals and families with assets across both jurisdictions.

- How the location of an asset determines which succession law governs it
- How your UK residence history can affect the IHT treatment of worldwide assets after moving to Guernsey
Does Guernsey Have Inheritance Tax?
No. Guernsey does not levy inheritance tax, estate duty, wealth tax, or a general gift tax. It also imposes no capital gains tax or VAT, and currently has no goods and services tax. A 3% Goods and Services Tax (GST), similar to VAT in the UK, is planned for introduction in 2029, subject to the required implementation conditions.
For internationally mobile and high-net-worth (HNW) individuals and families, the absence of these taxes can be relevant when structuring investments and planning the transfer of family wealth.
For UK individuals, the absence of Guernsey inheritance tax must be considered alongside their continuing UK IHT exposure. This applies both to those relocating to Guernsey and those who remain UK residents while owning assets there.
Since 6 April 2025, the UK’s IHT rules have generally been based on long-term UK residence (LTR) rather than domicile status. Individuals who meet the LTR conditions can remain subject to UK IHT on their worldwide assets even after moving to Guernsey. The rules can continue to apply for a specific period after leaving the UK, making a person’s UK residence history a crucial consideration when assessing the tax implications of the relocation.
When assessing the potential UK IHT implications of a move to Guernsey, the key considerations are:
- UK residence status and history
- The location and ownership of assets
- The timing of the move
How Does Guernsey’s Tax System Work?
Guernsey’s tax system includes personal income tax, corporate tax, document duty, and social security contributions, among other taxes and charges. For expats relocating to or living in Guernsey, however, personal income tax is the main consideration when assessing how their residence and income sources will be taxed. The other taxes generally arise in specific circumstances, such as when operating a business, employing staff, or acquiring property.
Guernsey’s tax rules are based partly on an individual’s residence status and partly on the source of their income. There are four categories of individual tax residence, and the applicable category depends on the amount of time an individual spends in Guernsey and their residence elsewhere:
| Residence Status | Explanation | Tax Treatment |
|---|---|---|
| Resident only | An individual who meets the Guernsey residence test by spending at least 91 days in Guernsey in a calendar year, or at least 35 days in that year and 365 days over the preceding four years, but is neither solely nor principally resident. This generally includes someone who spends at least 91 days in another country during the year | Generally taxed on Guernsey-source income, with an option for eligible individuals to pay an annual standard charge of £50,000 instead |
| Solely resident | An individual who meets the Guernsey residence test, is not treated as resident elsewhere under Guernsey’s rules and is not principally resident | Taxed on worldwide income, subject to applicable allowances, reliefs and tax caps |
| Principally resident | An individual who spends at least 182 days in Guernsey in a calendar year, or at least 91 days in that year and 730 days over the preceding four years. Certain individuals taking up permanent residence may also qualify | Taxed on worldwide income, subject to applicable allowances, reliefs and tax caps |
| Non-resident | An individual who does not meet the conditions for Guernsey tax residence | Taxed on specified Guernsey-source income, including income from Guernsey land and buildings, subject to applicable exemptions |
For Guernsey tax purposes, a day of presence is generally counted if an individual is on the island at midnight. The day of arrival therefore counts where the individual remains overnight, while the day of departure generally does not.
Guernsey tax residence is separate from UK tax residence, which is determined under the UK Statutory Residence Test. Becoming resident in Guernsey does not automatically make an individual non-resident in the UK.
How Is Income Taxed in Guernsey?
Guernsey taxes individuals at a standard flat rate of 20% on their assessable income, subject to available allowances, reliefs, and deductions. Solely and principally resident individuals are generally taxed on worldwide income. Qualifying residents can elect to cap their Guernsey income tax liability, significantly limiting the amount of tax payable (subject to requirements). Income from Guernsey land and property is excluded from the non-Guernsey-source income cap.
Tax caps can be particularly valuable to HNW individuals with substantial foreign income. For 2026, the main arrangements are:
| Arrangement | What Does It Cover? | Maximum Annual Tax |
|---|---|---|
| Non-Guernsey-source income cap | Qualifying foreign income and Guernsey bank interest. Other Guernsey-source income is generally taxed separately | £160,000 |
| Combined cap | Qualifying and non-qualifying income, excluding Guernsey land and property income and certain pension or annuity payments, which are taxed separately | £320,000 |
| Resident only standard charge | An alternative charge for eligible resident-only individuals, rather than an ordinary tax cap | £50,000 |
An eligible individual with £500,000 foreign income would have a 20% income tax liability of £100,000 before allowances or reliefs, which is below the £160,000 cap. An individual with £1 million in qualifying foreign income would have a liability of £200,000 before the cap, so the £160,000 limit may be relevant. £5 million of qualifying foreign income would ordinarily produce £1 million in income tax, but the liability on that income can be capped at £160,000 where the election conditions are met.
The standard charge operates differently from these tax caps, and the appropriate arrangement depends on the individual’s residence classification and sources of income.
How Are Non-Residents Taxed in Guernsey?
Non-residents may still be liable to Guernsey income tax on certain Guernsey-source income, even though the jurisdiction does not levy inheritance tax. This can include:
- Income from Guernsey land and buildings, such as rental income
- Certain income from employment carried out in Guernsey
- Certain income from business carried out in Guernsey
The treatment of employment and business income depends on the applicable source rules and exemptions. Foreign investment income, such as dividends from overseas companies, is generally outside the Guernsey income tax charge for a non-resident.
A person who lives in France but owns a rental property in Guernsey may have to pay Guernsey income tax on the property’s rental income. The same person is not liable to Guernsey income tax on dividends from a portfolio of UK or US shares simply because they own a Guernsey property. The rental income may also be taxable in their country of residence, subject to any applicable double taxation relief.
A Guernsey property can create income tax obligations during the owner’s lifetime, even though its transfer on death is not subject to inheritance tax in Guernsey. This distinction is relevant when assessing wider inheritance tax planning arrangements.

What Happens to a Guernsey Estate After Death?
An estate containing Guernsey assets may require a formal administration process before those assets can be transferred. The process depends on:
- The type of asset
- Whether the deceased left a valid will
- The deceased’s domicile at death (for movable property)
When Is Probate Required in Guernsey?
A Grant of Representation is the document that authorises an executor or administrator to manage the deceased’s personal estate in Guernsey. If there is a valid will naming an executor who is able and willing to act, the grant will be a Grant of Probate. If there is no valid will or no executor able or willing to act, the grant will be Letters of Administration.
A Guernsey Grant concerns personal property rather than real property. A Grant of Representation is not required for directly owned Guernsey land or buildings, although different rules can apply if property is held through a company or the interest is leasehold.
Probate is not automatically required for every Guernsey estate. The asset holder, such as a bank or investment institution, decides whether it requires a Guernsey Grant before releasing assets. An institution may release a small account without probate but require a Grant for a larger balance.
Where a Grant is needed, the Probate Registry generally requires:
- The deceased’s death certificate
- The original will (where applicable)
- Details and valuations of the relevant Guernsey assets
- Evidence that the relevant asset holder requires a Guernsey Grant
If probate has already been obtained in England, Wales, Scotland, or Northern Ireland, that grant does not automatically extend to Guernsey. A separate Guernsey Grant will be necessary if the asset holder requires one.
How Much Does Probate Cost in Guernsey?
A probate fee is payable when a Grant of Representation is obtained for a deceased’s Guernsey personal estate. The fee depends on the gross value of the relevant personal estate at the date of death, rather than the value of all assets owned worldwide.
Under the Probate Registry tariff effective from 1 January 2024 and included in its 2026 guidance, the fee is calculated as follows:
| Gross Value of Relevant Estate | Probate Fee |
|---|---|
| Up to £50,000 | £150 |
| £50,001 to £60,000 | £175 |
| £60,001 to £70,000 | £200 |
| £70,001 to £80,000 | £225 |
| Over £80,000 | £225 + £50 for each additional £10,000 or part thereof |
| Over £50,030,000 | £250,000 maximum |
Probate fees are administrative charges, not inheritance taxes. They are payable only when a Grant of Representation is required. Additional charges may apply for certain documents or administration.
How Does Succession Law Apply to Guernsey Assets?
For immovable property situated in Guernsey, local succession law generally applies regardless of where the owner was domiciled. For movable property, the succession laws of the deceased’s domicile at death generally apply. A person living outside Guernsey can own Guernsey real estate that is subject to Guernsey succession rules, while the succession law of their domicile may govern their Guernsey bank accounts or investments.
Shares in a company holding Guernsey real estate may be treated differently for succession purposes from property owned directly. The law governing succession should also be distinguished from the local procedures required to administer or transfer assets.
Although UK IHT now generally uses long-term residence rather than domicile to determine the treatment of overseas assets, domicile remains relevant to succession law.
Individuals with assets in Guernsey and the UK should review their wills and wider estate arrangements together, rather than assume that one will or one jurisdiction’s succession rules will automatically apply to their entire estate. Titan Wealth International can help assess existing international estate structures and identify areas requiring further specialist review.
Are There Forced Heirship Rules in Guernsey?
The Inheritance (Guernsey) Law, 2011 abolished forced heirship and introduced greater freedom of testamentary disposition, allowing individuals to determine who should inherit their assets.
However, testamentary freedom is not absolute. Certain family members and dependants may be able to apply to the Royal Court if the deceased’s will or intestacy failed to make reasonable financial provision for them, subject to the applicable statutory conditions.
What Are the Intestacy Rules in Guernsey?
If there is no valid will, the estate is distributed according to the applicable intestacy rules. The determination of heirs depends on the deceased’s family circumstances and, for movable assets, the succession law applicable to the deceased’s domicile.
Where Guernsey intestacy law applies, the estate may pass as follows:
- Spouse or civil partner and children: For Guernsey real property, the surviving spouse or civil partner generally inherits one-half of the matrimonial home, with a right of enjoyment over the remaining half, and one-half of any other real property. The descendants inherit the remaining shares in equal proportions.
- Spouse or civil partner but no children or other descendants: The whole estate generally passes to the spouse or civil partner.
- No spouse or civil partner, only children: The estate is generally shared among the descendants.
- No spouse, civil partner, or descendants: The estate passes to other relatives according to the statutory order of succession, which can include parents, siblings, and more distant relatives.
- No qualifying relatives: If no person is entitled to inherit, the estate ultimately passes to the Crown.
The precise distribution can depend on the type of property and the family circumstances. Guernsey intestacy rules will not necessarily govern movable assets belonging to someone domiciled elsewhere.
How Does Moving to Guernsey Affect UK Inheritance Tax?
Moving to Guernsey does not automatically remove your worldwide estate from UK inheritance tax. Under the UK’s long-term residence (LTR) regime, which took effect on 6 April 2025, individuals who have been UK tax resident for at least 10 of the previous 20 tax years are generally treated as long-term UK residents for IHT purposes.
If you move to Guernsey after a prolonged period of UK residence, your worldwide assets may remain exposed to UK IHT during the applicable post-departure tail period.
UK tax residence, Guernsey tax residence and UK long-term residence for IHT are separate tests. The UK Statutory Residence Test determines whether you remain a UK tax resident, while your longer-term residence history determines whether overseas assets remain within the UK IHT scope.
The actual period of your liability to UK IHT depends on your UK residence history. The longer you have been a UK resident, the longer the post-departure tail under the general rules:
| Years as UK Resident | Post-Departure Tail Period |
|---|---|
| 10–13 years | 3 years |
| 14 years | 4 years |
| 15 years | 5 years |
| 16 years | 6 years |
| 17 years | 7 years |
| 18 years | 8 years |
| 19 years | 9 years |
| 20 years or more | 10 years |
The table summarises the general rules and assumes continued non-UK residence. The calculation depends on the individual’s residence history and the relevant tax years. Transitional provisions may also affect individuals who were non-UK residents in 2025/26 and met the former non-domicile or deemed-domicile conditions. Returning to a UK residence can change the position.
After the applicable tail period ends, UK-situs assets generally remain within the scope of UK IHT, including:
- UK residential or commercial property
- Shares and other investments in UK companies
- Interests in UK businesses or other UK-connected assets, where treated as UK-situs under the applicable rules
- UK-situs bank accounts
The legal situs of an investment is not necessarily determined by the location of the investment platform or custody account. Special rules can also apply to indirect interests in UK residential property and assets held through trusts or companies.
Lifetime gifts, transfers into trusts and changes to asset ownership may have separate UK IHT consequences, including where an individual remains a long-term UK resident after departure.
UK pensions also require review. From 6 April 2027, most unused pension funds and pension death benefits will be included in the estate for UK IHT purposes, under changes enacted in Finance Act 2026. Exceptions include qualifying death-in-service benefits and certain dependant’s pension benefits. The IHT treatment will depend on the individual’s circumstances and the relevant pension arrangements.
Reviewing your UK residence history, asset ownership and pension arrangements before relocating can help identify potential IHT liabilities and areas requiring specialist cross-border estate planning advice.
Complimentary UK-Guernsey Inheritance Tax and Estate Planning Consultation
Moving to Guernsey or holding assets there can have important implications for your UK inheritance tax position. Although Guernsey does not levy inheritance tax, your UK residence history, the location of your assets, and your existing estate arrangements can all affect how your wealth is taxed and passed to beneficiaries.
In a complimentary introductory consultation with Titan Wealth International, you will:
- Review your potential UK inheritance tax exposure, including how the long-term residence (LTR) regime and post-departure tail may affect your worldwide estate.
- Discuss your UK and Guernsey assets, pension arrangements, and succession planning, including considerations arising from the planned April 2027 pension inheritance tax changes.
- Understand how Titan Wealth International can support your wider cross-border estate planning, including coordinating your investments, pensions, and wealth structures with your long-term family and succession objectives.
Key Takeaway
Guernsey does not levy inheritance tax, estate duty, or wealth tax, but UK inheritance tax can continue to apply to individuals living in Guernsey or holding assets there.
For UK expats, the key consideration is the long-term residence (LTR) regime. Depending on your UK residence history, worldwide assets may remain exposed to UK IHT for up to 10 years after departure. UK-situs assets generally remain within scope even after the applicable post-departure tail ends.
Guernsey probate and succession rules also matter where an estate includes assets in both jurisdictions. The planned April 2027 changes to the IHT treatment of unused pension funds add another consideration for individuals with substantial UK pension arrangements.
Before relocating to Guernsey or restructuring your estate, review your UK residence history, asset ownership, pension arrangements, and wills together to establish how the two jurisdictions may affect the transfer of wealth to your beneficiaries. Titan Wealth International can help you assess these cross-border considerations and plan accordingly.
