Guernsey or Jersey?

Jersey covers around 116 square kilometres with a population near 100,000. Guernsey covers around 78 square kilometres with a population near 63,000. Jersey is roughly one and a half times the size in both land and people.

That difference shows up everywhere: more choice of schools, shops, restaurants and jobs in Jersey, and more anonymity. Less of all of those in Guernsey, and correspondingly more chance of being recognised in the queue.

Both islands charge a flat 20% income tax and neither levies capital gains or inheritance tax.

The thresholds differ. In 2026 the single person threshold in Jersey is £21,250, with a marginal rate band of 26% applied until the effective rate reaches 20%. In Guernsey the single person threshold in 2026 is £15,200.

Jersey has a 5% Goods and Services Tax, introduced at 3% in 2008 and raised to 5% in June 2011. Guernsey currently has no GST at all, and this is the difference most often cited by people choosing between them.

Do not assume it holds. On 8 June 2026 Guernsey's Policy and Resources Committee published a Tax Reform 2026 package proposing a 3% GST from 1 January 2028, along with an International Service Entities scheme modelled on Jersey's, together estimated to raise around £55 million a year.

It now goes to the States. A consumption tax has been rejected repeatedly here, most recently in 2024, and many recently elected deputies oppose it. So the honest position is that this is unresolved and actively contested. If the absence of GST is a material part of your decision, follow the debate rather than the current position.

The two islands take different approaches at the top end.

Guernsey uses statutory tax caps available to any qualifying resident as a formal entitlement, with no prior negotiation required. With effect from 1 January 2026, and unchanged since 2024, tax on non-Guernsey-source income is capped at £160,000 a year, and tax on worldwide income at £320,000 a year. Income from Guernsey land and property is taxed separately and sits outside the cap.

Jersey operates a High Value Resident regime, which is applied for through government rather than claimed as an entitlement.

Both islands are roughly 45 minutes by air from London and from Paris, and both are reachable by sea. On travel, they are more alike than different. More on the practicalities is on the getting around page.

The tax and geography comparisons are easy to research and mostly cancel out. The real difference is social, and nobody writes it down.

Jersey is big enough to be anonymous in. Guernsey is not. On an island of 63,000 you will be known, quickly, and that is either the best thing about the place or the thing that eventually drives you off it. It gets you inside faster than any city would, and it means your business is reasonably well known before you have decided to share it.

Choose accordingly, and be honest with yourself about which of those you actually want.
