What is Social Insurance Contributions (Guernsey)?
Guernsey Social Insurance contributions are mandatory payments made by employers and employees that fund the island's social insurance system, including unemployment benefit, sickness benefit, retirement pension, and other social security benefits. Contributions are collected by the States Insurance Authority and remitted via the ETI (Employees Tax and Insurance) monthly return system.
Current Rate (Ongoing — monthly for employers, annual for self-employed)
Employee: 7.0% of gross earnings; Employer: 6.5% of gross earnings; Self-employed: 11.0% flat-rate contribution (2025 rates, capped at upper earnings limit)
Example
An employee earning £50,000 per year pays 7% SI on earnings up to the upper earnings limit (£192,240 in 2025), giving SI of £3,500 (if all earnings are below the cap). The employer pays 6.5% = £3,250. Total cost to employer: £53,250.
How Social Insurance Contributions (Guernsey) works in Guernsey
Guernsey's Social Insurance system is governed by the Social Insurance (Guernsey) Law 1978 and subsequent ordinances. It is administered by the States Insurance Authority (not the Revenue Service), but contributions are collected jointly through the ETI return system alongside income tax.
**Contribution rates (2025)** | Category | Rate | Earnings threshold | |----------|------|-----------------| | Employee SI | 7.0% | On earnings between the lower earnings limit and upper earnings limit | | Employer SI | 6.5% | On the same earnings range | | Self-employed | 11.0% | Annual flat-rate or income-based contributions |
**Earnings limits (2025 approximate)** - Lower earnings limit: £7,020 per year (below which no SI is due) - Upper earnings limit: £192,240 per year (above which no SI is due on excess)
**The ETI return** Employers file the Employees Tax and Insurance (ETI) return monthly. This single return captures both income tax (deducted from employee pay) and SI contributions. The return is due by the end of the month following the payroll month. Late submission attracts a £250 late filing penalty.
**Benefits funded by social insurance** - Retirement pension (State pension) - Long-term incapacity benefit - Short-term incapacity benefit - Contributory unemployment benefit - Maternity benefit - Bereavement benefits
**Self-employed contributions** Self-employed individuals pay contributions annually. They must register with the Social Security Department within 28 days of starting self-employment. The self-employed contribution covers the same benefit entitlements as employed persons.
**Guernsey SI vs UK National Insurance** Guernsey SI is similar in concept to UK National Insurance but operates independently. There is a reciprocal arrangement with the UK for periods of contribution, but they are separate systems. Moving between Guernsey and the UK may affect pension entitlements and should be planned carefully.
