‘Principally resident’ and ‘solely resident’ individuals are both liable to Guernsey income tax on their worldwide income. ‘Resident only’ individuals are either taxed on their worldwide income or alternatively taxed on Guernsey-source income and can opt to pay a set charge of GBP 30,000 in respect of non-Guernsey source income and no additional liability will arise on this income in Guernsey.
Personal income tax rates
Tax is payable at the rate of 20% on net income after allowances (see the Deductions section for a description of allowances).
It is possible for a Guernsey resident individual to elect for a cap on their income tax liability. Elections can be made for a liability cap of GBP 130,000 to apply for an individual or couple on non-Guernsey-source income, and the liability cap can be increased to GBP 260,000 if an election is made for the cap to apply to an individual or couples' worldwide income.
Furthermore, an election for a liability cap of GBP 50,000 can be made for individuals who purchase open market property on the island in excess of GBP 1,500,000 in the year they take up permanent residence. The cap is applied to an individual or couples' worldwide income and is also available for the three consecutive years after the year of arrival.
