Guernsey charges a flat 20% income tax, with no capital gains tax, no inheritance tax and no wealth tax. What makes it different from almost anywhere else is the tax cap: however much you earn abroad, your Guernsey income tax on it can be capped at £160,000 a year.
This guide covers Guernsey personal tax for the 2026 year of charge (1 January to 31 December 2026): the tax caps, the standard charge, residence, social security, housing rules and the October 2026 tax reform.
The key question is simple. How much do you earn, and where does it come from? For most people Guernsey is a straightforward 20% system with social security on top. For very high earners, the caps change everything.
What's changed: for 2026, the personal allowance rose from £14,600 to £15,200, the point where allowances start to be withdrawn rose from £82,500 to £85,000 and the standard charge rose from £40,000 to £50,000. Social security rates went up slightly, to 7.5% for employees, 12.4% for the self-employed and 11.8% for non-employed people under pension age. On 2 October 2026 the States agreed a tax reform package with a 3% GST and a lower 15% income tax band (see Filing and deadlines). It still has to be legislated, so it is Proposed, not law.

Guernsey's tax caps and the standard charge
Why do wealthy families choose Guernsey? Because the flat 20% rate stops at a fixed sum. Once your tax would pass a cap, you simply pay the cap.
Image 1 — Guernsey's tax caps put a ceiling on the 20% rate
There are three caps for Guernsey residents in 2026:
£160,000 on qualifying income. This covers income from outside Guernsey plus Guernsey bank interest. Other Guernsey income, such as a Guernsey salary, is taxed at 20% on top.
£320,000 on worldwide income. This covers all your income, except income from Guernsey land and property and certain pension payments, which are taxed on top.
£60,000 open market cap. For new residents who pay £50,000 or more in document duty on a property on Part A of the Open Market Register, bought up to 12 months before or after they take up permanent residence. You must not have been resident in Guernsey in the previous 3 years. The cap runs for the year you arrive and the 3 years after.
The caps only help very high earners: at 20%, tax reaches £160,000 at roughly £800,000 of income. In a capped year you get no personal allowance, and self-employed or non-employed people pay social security at the maximum weekly rate. Since 2023 each spouse elects separately.
The standard charge for part-time residents
If you're resident in Guernsey but not solely or principally resident, you can elect to pay the standard charge instead of tax on your worldwide income. It is £50,000 for 2026. You then pay no Guernsey tax on non-Guernsey income. Guernsey income other than bank deposit interest is still taxed, but the standard charge can be set against that tax. You lose all allowances, reliefs and deductions in a year you elect.

When you become tax resident in Guernsey
Guernsey counts the midnights you spend on the island in each calendar year. There are three levels of residence:
Resident: you spend 91 days or more in Guernsey in the year, or 35 days or more if you spent at least 365 days in Guernsey over the previous 4 years.
Solely resident: you're resident in Guernsey and not resident anywhere else that year. Spending 91 days or more in another place counts as being resident there.
Principally resident: you spend 182 days or more in Guernsey, or 91 days or more after spending 730 days in Guernsey over the previous 4 years. Someone who moves to take up permanent residence can also qualify.
All residents are taxed on worldwide income. If you're resident but neither solely nor principally resident, you get only part of the personal allowance, and you can choose the standard charge instead.
Leaving takes planning. You're non-resident in a year where you spend fewer than 91 days in Guernsey, but the 4-year lookback means 35 days can still make you resident for a few years after you move away. Guernsey has no exit tax for individuals.

Worked example
You're single and earn £75,600 (about US$100k) from a Guernsey employer in 2026.
Your income tax is £12,080: 20% of £60,400, after the £15,200 allowance.
Your employee social security is £5,670: 7.5% of your whole salary.
Your all-in bill is about £17,750, or 23% of your salary. The employee contribution has no allowance, so it weighs most on lower salaries.
Freelancing in Guernsey
If you're self-employed, your profit is taxed at 20% after the personal allowance, and you pay Class 2 social security contributions of 12.4% on your earnings, up to £196,560 a year. The minimum is £23.81 a week.
On £75,600 of profit, income tax is £12,080 and contributions are £9,374. That's about £21,454, or 28% all-in. You pay through interim assessments during the year, with a final assessment after you file.
👉 Guernsey Revenue Service: understanding assessments
Crypto, investments and pensions
How is crypto taxed in Guernsey? There is no capital gains tax, so a gain on crypto you hold as an investment isn't taxed. The Revenue Service hasn't published specific guidance on crypto for individuals. If you buy and sell often enough to be trading, the profits can be taxed as income at 20%.
The same applies to shares and funds. Gains are untaxed, but dividends and interest are income, taxed at 20% above your allowance. On a US$1m portfolio (about £756,000) earning £30,240 of income and £30,240 of gains, income tax is £3,008, about 5% of the total return. If you're non-employed and under pension age, social security of 11.8% also applies to your income above an allowance of £11,122. That adds £2,256 and takes the all-in cost to about 9%.
Pensions from abroad are taxed at 20% like any other income. If you receive a UK pension and complete a DT Individual form, you pay only Guernsey tax on it. Guernsey pension schemes let you take a tax-free lump sum of up to 30% of the fund, capped at £203,000, from age 50.
A retiree over pension age with a £30,200 (US$40k) foreign pension and £15,100 of investment income pays £6,020 in tax and £1,299 in contributions, about 16% all-in.
Guernsey has no capital gains tax, inheritance tax, estate duty or wealth tax.

Social security
Guernsey social security contributions are collected by the Revenue Service and fund pensions, health and long-term care. Unlike the UK, it isn't only for workers. People living on savings, investments or pensions pay too.

Non-employed people with income below £24,960 before the allowance are exempt. If you don't apply to pay on your actual income, you're charged the maximum weekly rate, which is £420.80 under pension age and £135.51 over it.

Double tax treaties
Does Guernsey have double tax treaties? Yes. Guernsey has 15 comprehensive double taxation arrangements in force: with the UK, Jersey, the Isle of Man, Malta, Cyprus, Luxembourg, Liechtenstein, Monaco, Estonia, Singapore, Hong Kong, Qatar, Bahrain, Mauritius and the Seychelles. The newest, with Bahrain, came into force on 26 November 2025.
It also has 13 limited agreements, covering individuals or shipping and aircraft, including with Australia, Ireland, Japan, the Netherlands, New Zealand, Poland and the Nordic countries. Under the UK agreement in force from 2020, a UK resident working in Guernsey for 183 days or less in 12 months is usually taxed only in the UK, unless the employer is in Guernsey.

Housing, permits and long stays
Guernsey has no digital nomad visa. Two systems decide where you can live: immigration, which follows the UK, and Population Management, which controls housing and work.
Guernsey is part of the Common Travel Area, so British and Irish citizens need no visa. Other nationals follow the UK visa rules, and non-visa nationals have needed an Electronic Travel Authorisation (ETA) since 23 April 2026 for visits of up to six months. Visitors working remotely for an employer outside Guernsey can do so for only 10 days in any 30, and no more than 90 days in 12 months, without a Population Management permit or certificate.
Housing is split into two markets. Anyone can live in Open Market housing, subject to immigration rules. Living in the Local Market needs you to be residentially qualified or to hold a permit, such as a Short Term Employment Permit (up to 1 year, renewable to 3 years) or a Long Term Employment Permit (up to 8 years, after which you can expect to become an Established Resident). Those permits are tied to a job.

Filing and deadlines
Everyone files their own return, whether married or not. The deadline for 2025 returns is 30 November 2026, and on the same pattern 2026 returns are due by 30 November 2027. A penalty applies automatically if your return is late.
Employees and pensioners have tax deducted at source. If you're self-employed or have other income, the Revenue Service issues an interim assessment that sets quarterly payments during the year. If you use a cap, you don't need to complete a full return.
The 2026 tax reform
On 2 October 2026 the States of Deliberation directed the Policy & Resources Committee to implement the Tax Reform 2026 package. The package includes a 15% rate on the first £28,000 of taxable income, a £600 higher personal allowance, an £11,122 social security allowance for workers, and employee and self-employed contributions rising to 8.5% and 14.5% from 2028. It also includes a 3% GST, planned for 2028. An amendment agreed in the debate would raise GST to 4% and then 5%, 24 and 48 months after the changes start, with 5% as the maximum. The laws still have to be made, so this is Proposed, not law.
