Jersey, Guernsey and the Isle of Man: Outside the UK VAT Area

Why do GB sellers treat Jersey and Guernsey as international destinations, what customs forms and Jersey GST apply to a research order, and why is the Isle of Man different?

Most UK online sellers offer delivery to the mainland and quietly leave out the Channel Islands. The reason is tax and customs, not distance. Jersey and Guernsey are not part of the UK for VAT, so goods sent to them are treated as exports. The Isle of Man, by contrast, is treated as part of the UK for VAT and customs, so a parcel there is a domestic one.

For a research order the differences matter because they decide which declaration travels with the parcel, who collects tax and how long clearance takes. The pages cited below were read on 10 October 2026. Some figures differ between official pages and some carriers publish their own rules, so read the live page for the destination before ordering.

Three islands, two tax positions

HMRC's export notice says the Channel Islands are not part of the UK for fiscal purposes, that supplies of goods sent there are regarded as exports and may be zero-rated, and that goods subject to excise or customs controls always require an export declaration ^[6]. The same notice says that for VAT purposes references to Great Britain include the Isle of Man, and that goods sent to the Isle of Man from Great Britain are domestic supplies ^[6].

The Isle of Man Government describes the basis: the Island is treated as part of the United Kingdom for customs, excise and VAT, and for those duties the two territories are treated as if one. It also notes the Customs and Excise Agreement covers many but not all indirect taxes, so a rare exception is possible ^[5].

Customs forms on the way out of Great Britain

A parcel to Jersey or Guernsey leaves the UK VAT area, so a postal or courier consignment needs a customs declaration. Guernsey Post explains the postal forms from its own side: a CN22 label for items under £270 in value, and a CN23 for items over £270, for large parcels of any value and for anything sent by Parcelforce ^[4]. That page is written for items leaving Guernsey, so treat it as a description of the form thresholds, not of the UK sender's duty.

Carriers apply their own rules on top. Some generate the declaration automatically when the postcode begins with GY or JE; others expect the sender to supply it. The sender's own carrier page, or the service booking screen, is the authority. Whichever form is used, the description and value must be accurate. A sample described as having no value invites a query at the other end.

None of this applies to the Isle of Man, where HMRC treats goods sent from Great Britain as domestic. A carrier may still ask for postcode-specific handling, but there is no customs declaration for an ordinary consignment in the way there is for the Channel Islands.

Jersey GST on imported orders

Jersey charges Goods and Services Tax, at 5 per cent for nearly all goods. The Government of Jersey page for overseas retailers states a de minimis of £60: goods valued above it from a retailer not registered for Jersey GST attract GST on importation, while a retailer that is registered charges GST at the point of purchase ^[1].

The page says an overseas retailer must register where its sales to Jersey consumers exceed, or are likely to exceed, £300,000 in a rolling twelve months, and may register voluntarily below that ^[1]. It also says the threshold applies to goods imported by private individuals, not to businesses ^[2].

The page is not internally consistent on dates. One section gives 1 July 2023 as the start of the £60 rule and another gives 1 January 2023 ^[1]. The practical point is that the £60 figure is the current one on the live page. Read the figure there on the day you order, because a threshold that the page itself says will eventually be removed can change.

To declare goods in Jersey, the recipient uses an online customs account; the customs service or the shipper contacts the recipient, GST and any duties are paid online and the goods are released ^[2]. The same page says supplies of goods removed from the UK to Jersey should be zero-rated for UK VAT, so a GB seller should not add UK VAT to the price ^[2].

Guernsey: customs union, forms and checks

The States of Guernsey describe a customs union with the UK, Jersey and the Isle of Man. Goods from outside it, meaning anywhere other than those three, need an electronic import declaration through the Guernsey Electronic Manifest System. Goods from the UK, Jersey and the Isle of Man generally do not need one, except goods in transit that have not been cleared there and excise goods, which need a declaration wherever they come from ^[3].

The Guernsey pages read for this article discuss customs tariffs and excise but describe no import GST. Guernsey Post's guidance is explicit that postal items for repair, valuation or return can be held until the recipient completes Border Force forms ^[4]. If a figure matters to a purchase, ask Guernsey Customs or the carrier rather than relying on a general article.

Why the Isle of Man is different

The Customs and Excise Agreement between the Island and the UK means that, as the Isle of Man Government puts it, for VAT and customs and excise duty purposes the territories are treated as if one. HMRC guidance generally applies to Isle of Man businesses and individuals, subject to exceptions, and most VAT and indirect tax revenue is pooled and shared ^[5].

For a buyer this means a UK seller can price and invoice an Isle of Man order as it would a mainland one. The practical differences are delivery time and carrier surcharges, not tax. The article on Highlands, islands and Northern Ireland covers surcharges within the UK.

Transit time, temperature and returns

An island destination adds a sea or air crossing and, for the Channel Islands, a customs step. Any of those can add a day. For material that is sensitive to temperature, extra days in a depot are the main risk, and they are unpredictable. Ask the supplier about service level, dispatch day and the carrier's published transit time to that postcode.

Returns reverse the paperwork. A parcel going from Jersey or Guernsey to Great Britain leaves the Channel Islands and enters the UK, so it needs its own declaration and may be held for clearance. Agree return procedures with the seller before the first order, in writing.

1. Confirm the seller ships to the island postcode at all.
2. Ask who collects any tax on arrival, and at what stage.
3. Confirm which declaration the carrier will attach and who prepares it.
4. Read the destination government's page for the current threshold on the day you order.
5. Keep invoice, declaration and tracking together as one record.
