Key Takeaways
- Guernsey levies stamp duty as Document Duty on chargeable transactions such as property transfers, bonds and leases, which affects non-resident buyers and investors.
- Buyers of second homes and buy-to-let properties face an additional duty charge on top of the graduated rate scale that applies to property transactions.
- Share transfers can fall within an anti-avoidance regime, so companies and investors holding property through entities should assess their exposure.
- Document Duty is self-assessed and paid by the parties, with exemptions and reliefs available for certain family transactions, charities and downsizing.
Introduction to Stamp Duty in Guernsey: Why It's Called Document Duty
If you are looking for stamp duty in Guernsey, the term you actually need is document duty. The island does not levy stamp duty in the UK sense, nor does it impose a separate transfer tax; instead it collects a constitutionally distinct charge when a property document is registered at the Royal Court. That levy, known formally as document duty, is the functional substitute for both stamp duty land tax and transfer tax.
Document duty is set by the States of Deliberation through subordinate Ordinance and is payable on prescribed documents presented to the Court. The States of Guernsey administers the regime, with collection handled at the point of registration.
This article explains how the charge works: what triggers it, the graduated rate scale, the surcharge on second homes, the anti-avoidance rules on share transfers, and the exemptions available. It is most relevant to foreign investors, non-resident buyers, and advisers weighing whether to acquire Guernsey real property directly or through a company.
The Legal Basis: The Document Duty (Guernsey) Law 2017 and Related Legislation
The governing statute is the Document Duty (Guernsey) Law 2017, which came into force on 15 November 2017. It replaced the 1973 Law and the 2003 Ordinance, and was drafted to give buyers and sellers greater clarity than the regime it superseded.
A companion measure, the Document Duty (Anti-Avoidance) (Guernsey) Law 2017, closes a gap that allowed property to change hands without a registrable conveyance. Transactions that transfer real property in a form resembling ownership are now treated like conveyances at the Greffe, with duty charged at the same rate.
Rates themselves do not appear in the primary Law. They are prescribed by the Document Duty (Rates) Ordinance 2017, made under section 6(1), which the States may amend without reopening the Law.
That power has been used repeatedly. The contents deduction was changed by a 2019 amendment, a non-PPR surcharge arrived through a 2022 amendment effective 2 November 2022, and the progressive bands were revised by an amendment ordinance published on 8 November 2024.
HM Greffier runs the scheme and may refer matters to the Director of Income Tax. The framework also provides for appeals and creates offences for false or misleading statements.

What Counts as a "Chargeable Transaction" (Property Transfers, Bonds and Leases)
A chargeable transaction is the acquisition by any person of an interest in real property, or the creation of a charge against real property through registration of an hypothéque, the local form of legal charge or bond. Without payment of duty, the document recording that transaction cannot be registered at the Greffe.
The definition reaches further than a simple sale. Creating or transferring a right of life enjoyment counts, such as a parent selling to a child while keeping the right to live in the property.
Grants and assignments of leases stay outside the charge. So the lease route does not attract document duty, even though an outright transfer does.
Registering a bond that secures a loan against Guernsey real property is a chargeable transaction, but the rate applied to the amount secured is 0.0%.
Where the consideration looks inadequate, HM Greffier may treat the deal as not at arm's length and assess duty on market value instead. Boundary adjustments and exchanges of very small land parcels get no concession; market value must be declared, with no minimum-value floor. Delaissances and partages are chargeable unless they qualify as a family transaction or fall between co-heirs.
Duty attaches to the realty alone. The contents of a property are excluded from the calculation.
Document Duty Rates: The Graduated Scale Explained
Document duty works on a graduated basis, applying each rate only to the slice of value within its band rather than to the whole price. For a principal private residence, the scale below took effect on 8 November 2024, after the 2024 budget lifted thresholds by 25% to reflect inflation.
| Portion of property value | Rate |
|---|---|
| First £300,000 | 2.25% |
| £300,001 to £500,000 | 3.50% |
| £500,001 to £950,000 | 4.00% |
| £950,001 to £1,250,000 | 4.25% |
| £1,250,001 to £2,500,000 | 4.50% |
| £2,500,001 to £5,000,000 | 5.50% |
| Above £5,000,000 | 7.00% |
The threshold uplift cut duty on the average house purchase by more than £1,000. At the same time a new top band of 7% was introduced for the part of any transaction exceeding £5,000,000.
For arm's length deals, duty is calculated on the consideration paid. Where a transaction is not at arm's length, the figure used is the market value of the realty transferred.
Only the property value is charged, never the contents. A split of 97.5% property to 2.5% contents is accepted as standard, the contents allowance having been reduced from 5% to 2.5% by the 2019 amendment.

The Additional 2% Duty on Second Homes and Buy-to-Let Properties
A residential purchase that will not serve as the buyer's main home, or that of a close family member, carries a surcharge. Across every band, the rate rises by two percentage points.
For an investor, the entry band of 2.25% becomes 4.25%, and each higher band shifts up by the same margin. Owner-occupiers buying a principal private residence stay on the standard scale.
The non-PPR rates apply to all transactions registered from 2 November 2022. The policy is deliberate: the States use a higher charge on second homes and buy-to-lets to encourage larger homes back onto the market for resident buyers.
The 2022 ordinance contained a sunset clause that would have ended the surcharge for transactions registered on or after 1 January 2025; the 2024 amendment re-enacted the regime on a continuing basis, so the 2% uplift remains in force.
Document Duty on Share Transfers: The Anti-Avoidance Regime
Under the old rules, ownership of a property could pass without any registrable document. Transferring the shares in a company that held the property moved control without triggering a conveyance, and therefore without duty.
The Anti-Avoidance Law closes that route. Its central target is the sale of shares in a company that owns Guernsey real property.
The charge now bites on "relevant transactions", meaning a transfer that confers a "significant benefit" on the buyer. That benefit includes the right to occupy, to control who occupies, or to receive rent or income from the property.
Rates under the Anti-Avoidance regime mirror those of the main Law, set out in the Document Duty (Anti-Avoidance) (Rates) Ordinance 2017. One difference matters: duty here is assessed on market value, with no option to use the consideration paid, and all parties to the transaction are jointly and severally liable.
Limited carve-outs apply to partnership property and to property used for the business of a company or partnership. Even so, an exempt transaction must still be disclosed to HM Greffier; silence is not an option.

Exemptions and Reliefs (Family Transactions, Charities, Downsizing and More)
A range of transfers fall outside the charge entirely. The categories below are the ones a foreign owner is most likely to encounter.
Family transactions. Transfers between close relatives are exempt, including parent and child, grandparent and grandchild, siblings, uncles or aunts and nephews or nieces, spouses or civil partners (current or former), and cohabitees. The exemption holds even where full market value changes hands.
Charities and housing providers. Transfers to a Guernsey-registered charity, to a friendly society incorporated under the Friendly Societies Act 1974 or 1992, or to a recognised housing provider such as the Guernsey Housing Association are exempt. A charity registered elsewhere does not qualify.
Corporate and trustee restructuring. Several intra-group and ownership-aligned moves are relieved:
- A company conveying property to its beneficial owner
- A transfer to another company in the same beneficial ownership
- A transfer to a wholly-owned subsidiary, or between fellow subsidiaries of a common holding company
- An individual conveying property to a company they solely own
- Trustees conveying to beneficiaries where the trust holds through an underlying company
Other exemptions. Conveyances between co-heirs, partages, transfers by will, and interests acquired under a court order are all outside the charge.
Downsizing relief deserves separate attention. On a qualifying purchase of a smaller replacement home, the first £400,000 of value is exempt, with duty payable only on the excess.
To qualify, the new property must be at least 25% smaller by reference to its Tax on Real Property assessment, and the property sold must have been your principal private residence for the preceding two years. Introduced in January 2023 and extended for two further years under the 2024 budget, the relief now caps at £13,750 and can be claimed only once.
How Document Duty Is Calculated, Self-Assessed and Paid
The law places the duty of self-assessment jointly and severally on both transferor and transferee. They must correctly calculate the amount due, though in practice the purchaser pays it.
Under the Anti-Avoidance regime the procedure is more formal. A self-assessment form goes to HM Greffier within 28 days of completion, with supporting evidence of market value and payment of any duty owed; a pre-assessment can be obtained in advance.
Where a transaction is claimed to be exempt, the parties file a declaration to that effect. A valuation is not needed at that stage unless HM Greffier later asks for one.
HM Greffier administers collection but can refer cases to the Director of Income Tax, who holds enforcement powers, can make formal assessments, and may impose penalties for non-compliance. Because registration cannot proceed until duty is paid, payment effectively gates the transaction.
A practical point for the calculation: since 1 January 2018, a contents deduction of 2.5% of the total purchase price is accepted without further evidence as the non-taxable portion, replacing the earlier 5% allowance.
Document Duty in Alderney and Across the Bailiwick
The 2017 Law applies to the island of Guernsey alone. Alderney and Sark fall outside it and set their own charges on property transfers.
In Alderney, document duty continues under the pre-2017 legislation, and a separate charge known as Congé remains payable. The rates differ slightly and are obtained from the Alderney Court Office, with duty collected on Alderney property paid to the States of Alderney.
Sark operates its own arrangements for any property transfer charge within the Chief Pleas framework. If you are buying outside Guernsey itself, confirm the local rules before assuming the figures in this article apply.
What Document Duty Means for Companies, Investors and Property Buyers
The most consequential effect of the 2017 reforms is on holding structures. Once a share transfer in a property-owning company attracted the same duty as a conveyance, the old advantage of "enveloping" property in a company largely fell away, and many buyers chose to hold personally instead.
Holding through a company can still make sense for succession, confidentiality, or wider planning reasons. The point is simply that document duty no longer disappears when you sell the shares rather than the bricks.
For investors, the headline cost is the 2% surcharge on non-PPR residential property, applied across every band. That uplift materially raises acquisition cost against an owner-occupier buying the same home.
The sums involved can be large. Two of the island's most expensive open market properties sold in 2021 for a combined £28,950,000, producing £1,493,443 in document duty.
New residents who buy an Open Market property and pay document duty of £50,000 or more have been able to cap their annual tax liability for the four years after arrival, subject to changes under the 2024 budget.
One structural risk is worth flagging. All parties to a transaction are jointly and severally liable, so the documents should state clearly which party, normally the purchaser, is paying the duty.
The Outlook: Recent Changes and Possible Reform
The direction of travel is incremental rather than wholesale. The 2024 budget lifted thresholds by 25%, added the 7% band above £5,000,000, and extended downsizing relief with a higher cap, all taking effect on 8 November 2024.
Pressure for a blanket exemption on entry-level homes has surfaced, with commentary in 2022 arguing the threshold should sit at no less than £350,000 given island prices. No such exemption has been enacted.
Two developments are worth watching. A proposal to introduce a goods and services tax from 2027 appeared in the 2025 Budget, which could interact with how thresholds are set in future, and a Policy Letter on minor changes to the 2017 Law has gone to HM Greffier for debate.
Given how much the charge contributes to public finances, any move to curb it is unlikely to gain traction. Expect continued fine-tuning through Ordinance rather than a fundamental rewrite.
Conclusion
For a non-resident acquiring Guernsey property or structuring ownership through a company, the anti-avoidance regime on share transfers is the point that most often catches advisers off guard, because it means the duty question does not disappear simply by holding assets through an entity. That single exposure, combined with the additional charge on second homes and buy-to-let purchases, is where the real cost differential lies and where pre-transaction analysis pays for itself.
Self-assessment places the compliance burden squarely on the parties, so the practical next step is to map the intended structure against the chargeable transaction rules and the available exemptions before any instrument is signed, not after.

Frequently Asked Questions
No, Guernsey does not levy stamp duty in the UK sense, nor a separate transfer tax. The equivalent charge is document duty, collected when a property document is registered at the Royal Court under the Document Duty (Guernsey) Law 2017.
For a principal private residence, rates run on a graduated scale from 2.25% on the first £300,000 up to 7% on any part above £5,000,000, effective 8 November 2024. Each band applies only to the slice of value falling within it, and the calculation excludes contents, which attract a standard 2.5% deduction.
Yes. Residential property that will not be the buyer's main home, or a close family member's, carries a 2% surcharge across every band, so the entry rate rises from 2.25% to 4.25%. This non-PPR uplift has applied to transactions registered since 2 November 2022 and was made permanent by the 2024 amendment.
No. The Document Duty (Anti-Avoidance) (Guernsey) Law 2017 makes a share transfer in a property-owning company chargeable, assessed on the market value of the realty. All parties are jointly and severally liable, and even an exempt transaction must still be disclosed to HM Greffier.
Yes. Transfers between close relations, including parents and children, siblings, spouses or civil partners, and cohabitees, are exempt even where full market value is paid. A self-assessment declaration confirming the exemption must still be submitted, with a valuation provided only if later requested.
Duty is paid by the purchaser, with self-assessment a joint obligation of both parties. Under the anti-avoidance regime a self-assessment form must reach HM Greffier within 28 days of completion, and because registration at the Greffe cannot proceed until duty is settled, payment effectively gates the transaction.
