Guernsey sits 18th out of 217 in our world ranking, with a FiScore of 8.7 out of 10. Sixty-five square kilometres in the English Channel, thirty kilometres off the Normandy coast, a British Crown Dependency that is neither in the United Kingdom nor in the European Union.
One flat rate of 20%, and a cap that changes everything above a certain income.
The rates
| Tax | Rate |
|---|---|
| Personal income | 20% |
| Companies | 0% for most |
| VAT | none |
Twenty per cent is a flat rate, not a top bracket. The same 20% applies to the first pound of taxable income and to the last, which makes Guernsey unusually easy to model.
Corporate tax is 0% for most activities, with higher rates for regulated sectors.
There is no VAT at all, no capital gains tax and no inheritance tax.
The personal allowance is GBP 15,200 in 2026, but it melts away above GBP 85,000 of income: it is reduced by one pound for every five pounds above that threshold.
The Open Market cap
This is the door for anyone arriving with a high income.
Guernsey runs a two-tier property market. The Local Market is reserved for people with a connection to the island. The Open Market is open to anyone arriving from outside, at substantially higher prices.
Buying on the Open Market gives access to a tax cap of GBP 60,000 a year for the first four years of residence. Whatever you earn, your Guernsey tax stops there for that period.
Other general caps exist beyond those four years. Their level has moved several times and we do not freeze a figure here: that is the kind of number to confirm with a practitioner when the file is actually being put together.
Guernsey or Jersey?
The two islands look alike and differ on the details that decide.
Jersey is bigger, with a larger finance sector, and its High Value Residency regime taxes 20% on the first GBP 1.25 million of worldwide income and 1% above that, against a minimum annual contribution of around GBP 250,000.
Guernsey caps at GBP 60,000 for four years, which is far cheaper to enter, but time-limited and without Jersey's 1% marginal rate.
Roughly: Guernsey suits a high income that is not extreme, Jersey suits a very large fortune that intends to stay.
If you are British
Guernsey is a Crown Dependency, not part of the United Kingdom, so moving there is a genuine departure from the UK tax net rather than an internal move.
The statutory residence test still decides, and the day counts still bite. The proximity is the trap: a short flight does not make the ties disappear, and a home kept in England is exactly the sort of thing that keeps you resident. Read leaving the UK before anything else.
If you are American
Citizenship-based taxation applies whatever Guernsey does, and there is no United States income tax treaty with the island.
A capped Guernsey bill produces correspondingly little foreign tax credit, against a US liability that does not move. For an American, Guernsey is a place to live rather than a tax outcome.
The drawbacks
The Open Market is expensive. That is the real entry ticket, and it runs into millions for a decent house.
The island is small, and its social life has a reputation for being closed to anyone without ties.
Neither UK nor EU: no freedom to provide services into either, and a thinner treaty network than a member state's.
The weather is the English Channel's, which decides more departures than people expect.
So, who is Guernsey for?
- A high income over a defined period: GBP 60,000 capped for four years is one of the best ratios in Europe.
- Fund and insurance structures: the sector is specialised and long established.
- A very large fortune for the long term: compare with Jersey, whose 1% marginal rate eventually wins.
- A middling income: 20% on everything, without the cap, which is fine but no more than that.
