What is the personal income tax rate in Guernsey?

## Guernsey Personal Income Tax 2026

Guernsey has one of the simplest personal income tax systems in the world: a single flat rate of 20% on all income above your personal allowance. There are no higher bands, no surcharges, and no separate capital gains tax.

## The Core Figures (2025/2026)

| Category | Rate or Amount | |----------|---------------| | Tax rate | 20% flat | | Personal allowance (single) | £15,000 | | Married/civil partnership allowance | £30,000 | | Capital gains tax | None | | Inheritance tax | None | | Social insurance (employee) | 7% of earnings |

Residents are taxed on their worldwide income at 20%. You are resident if you: - Are in Guernsey for 182+ days in a calendar year, OR - Are present for 91+ days per year averaged over three consecutive years (and your principal place of abode becomes Guernsey), OR - Have Guernsey as your principal place of abode

Non-residents are taxed only on Guernsey-sourced income — for example, employment in Guernsey, rental income from Guernsey property, or director fees from a Guernsey company.

## Personal Allowances and Reliefs

The following are deductible from income before applying the 20% rate:

## The Standard Charge (Tax Cap)

High earners can elect to pay a fixed annual tax of £50,000 regardless of their actual income level. This is known as the 'standard charge'. Once elected, the individual pays £50,000 per year and no further income tax regardless of how much they earn.

This is valuable for: - Very high earners with significant overseas investment income - Business founders who receive large dividends from offshore companies - Retirees with substantial pension or investment income

Note: the standard charge does not protect against social insurance contributions, which are calculated separately.

## Filing the Personal Tax Return

The personal income tax return (IT1) is due by 30 November for the prior calendar year. It is filed online via the Revenue Service portal or on paper. The Revenue Service then issues an assessment; tax is due within 30 days of the assessment.

Employers deduct income tax monthly through the ETI (PAYE equivalent) system, so most salaried employees will have limited additional liability at the end of the year.
