Payroll Tax in Guernsey: ETI, Social Insurance & Filing

Introduction to Payroll Tax in Guernsey: Social Security Contributions and the ETI SystemCopy link to section

Guernsey does not levy a standalone payroll tax in the sense familiar from many other jurisdictions, where employers pay a separate percentage charge on their wage bill. What a foreign-owned business actually faces is a set of three payroll obligations: income tax withholding through the Employees' Tax Instalment (ETI) scheme, social insurance contributions under the Social Insurance (Guernsey) Law 1978, and secondary pension contributions. The employer element most closely resembling a payroll tax is the secondary Class 1 social insurance contribution, deducted and remitted alongside ETI withholding.

These rules apply to any entity that pays wages, salaries, or directors' remuneration on the island, including a company incorporated overseas but operating staff there. This article explains the rates, thresholds, registration steps, filing deadlines, and the special treatment of directors, contractors, and cross-border workers. The detail below matters most to a non-resident owner or adviser deciding whether to employ people through a Guernsey entity, and to those already running one. A useful starting reference is the States of Guernsey employer guidance.

The Legal Basis: The Social Insurance (Guernsey) Law 1978 and Annual Contribution OrdinancesCopy link to section

Social insurance in Guernsey rests on the Social Insurance (Guernsey) Law, 1978, which establishes three classes of contribution: Class 1 for employed persons and their employers, Class 2 for the self-employed, and Class 3 for the non-employed. The States set fresh contribution rates and earnings limits each year by ordinance.

For 2026, the governing instrument is the Social Insurance (Rates of Contributions and Benefits etc.) Ordinance, 2025, which came into force on 1 January 2026 (with one provision taking effect on 5 January 2026). The income-tax side of payroll runs on a separate footing: the ETI scheme draws its authority from the Income Tax (Guernsey) Law, 1975, and operates alongside, but distinct from, the social insurance framework.

Classification rules under the 1978 regulations have been refined to capture certain working arrangements. Controlling directors of limited companies are treated as employed persons from 1 January 2025, and all labour-only contractors and subcontractors in construction are likewise classified as employed.

Class 1 Contributions: Employer (Secondary) and Employee (Primary) Rates for 2026Copy link to section

Class 1 contributions split into a primary share paid by the employee and a secondary share paid by the employer. Both are calculated as a percentage of assessable earnings within set limits.

These figures sit slightly above the prior year. For 2025 the employer rate was 7.0% and the employee rate 7.4%, themselves increases on the 6.9% and 7.2% applied before. Contributions are due from both employer and employee for any employed person over school-leaving age and under 65.

The Contribution Base: Earnings Limits, Included Pay, and the Treatment of Dividends and BenefitsCopy link to section

Contributions apply to gross earnings between a lower limit, which triggers employer liability, and an upper limit, beyond which no further contributions arise. For 2026 the upper weekly limit is £3,780.00, the upper monthly limit £16,380.00, and the annual ceiling £196,560. By comparison, the upper monthly limit for 2025 stood at £15,717.

The lower earnings limit marks the point at which an employer becomes liable. For 2025 this was set at £797.33 per month; the equivalent 2026 monthly figure should be confirmed against the official rates leaflet, as the published data does not state it explicitly.

The percentages are applied to basic salary together with bonuses, overtime, commissions, and similar earnings, capped at the upper limit for each pay period. Several less obvious items are caught as well.

• Dividends: dividends paid to an employee by the private company that employs them, or by an associated company as defined in the Companies (Guernsey) Law 2008, count as earnings for social security purposes.
• Benefits in kind: these must run through the ETI scheme, though the first £450 of certain benefits is exempt from tax.
• Exclusions: lump-sum redundancy payments carry no liability, pensions of any kind are excluded, and directors' fees generally attract no contribution unless specific conditions apply.

Employer Registration with the Revenue Service for Payroll ObligationsCopy link to section

Registering with the Revenue Service is a legal requirement before any business takes on staff. On registration you receive two reference numbers, one for tax and one for contribution deductions, and both must be quoted when you contact the Revenue Service and when you file through the Returns Creator system.

Deductions reach a wide group of workers. Anyone receiving a wage, salary, or pension is included, alongside company directors, part-time and casual staff, and those supplying labour only.

Same-day registration of a business and its staff is available through both the income tax and social security functions, and this must be completed before employment begins. The Customer Service (Employers) team can allocate an employer reference and supply reporting software, reachable on (01481) 225700 or at employer@gov.gg.

Calculating and Deducting Contributions Through the Employees' Tax Instalment (ETI) ScheduleCopy link to section

The ETI scheme is the mechanism by which an employer withholds income tax from staff and remits it to the Revenue Service. It covers everyone holding an office or employment, including directors, part-time and casual workers, and subcontractors. Income tax under ETI is withheld at a flat 20% rate.

A coding notice issued for each employee states how much that person may earn weekly or monthly before tax falls due. Social insurance is then calculated separately on the same payroll run, applying the Class 1 percentages to gross earnings between the lower and upper limits.

Benefits in kind must pass through the scheme by adding the value of the benefit to the employee's gross pay in the period it was provided, with tax deducted as though the benefit had been paid in cash. Where deduction at source is not possible, a benefits in kind form must be filed annually by 15 February. PwC's tax summaries set out how the ETI mechanism interacts with the social insurance thresholds.

Quarterly Returns and Remittance Deadlines for Payroll ContributionsCopy link to section

Most employers report ETI and social security on a quarterly cycle. Throughout each quarter you deduct tax on each payday, then return the details of gross wages and deductions, with payment, by the 15th of the month following the quarter end.

Larger employers, or those above defined thresholds, may be required to remit monthly instead, with the same 15th-of-the-following-month deadline. Returns are filed electronically through the Returns Creator portal at rc.gov.gg.

If a quarterly return has gone in with an error, you correct it by emailing eti@gov.gg with your employer reference numbers, the employee's personal tax reference, and the details to be amended.

Secondary Pension Scheme Contributions (Your Island Pension): Mandatory Employer and Employee PaymentsCopy link to section

A third payroll stream now sits alongside ETI and social insurance. The Secondary Pensions Law commenced on 1 July 2024 for larger employers, with full reach from 1 October 2025 extending to firms with a single employee. Employers must set up an approbated pension scheme, such as Your Island Pension, and contribute to it.

From 1 January 2026 the minimum contribution rates are 1% of relevant earnings for employers and 1.5% for employees. Where an employer's operative date does not fall until 2026, those same minimums apply.

Enrolment works on an automatic basis. All eligible employees are enrolled unless they opt out, and those who opt out must be re-enrolled every three years.

• Enrolment may be deferred for up to three months to accommodate probationary periods and staggered start dates.
• Contributions are calculated on all pay up to the social security upper earnings limit.
• Employees earning below the lower earnings limit are not designated employees and fall outside the scheme.
• Quarterly secondary pension returns must be submitted to the Revenue Service, which monitors compliance.
• An employer may pay more than the statutory minimum, allowing the employee to contribute less or not at all.

The minimum rates rise on a phased basis over eight years. The endpoint for employee contributions under a minimum-rate scheme is 6.5%, and 3.5% for employers, as set out in the States pension schedule.

Special Cases: Labour-Only Contractors, Controlling Directors, and Cross-Border WorkersCopy link to section

Several arrangements that look self-employed are treated as employment for contribution purposes, and a foreign owner should test each working relationship against these rules before assuming no payroll obligation arises.

Labour-only contractorsCopy link to section

All labour-only contractors and subcontractors in construction are classified as employed persons. Such workers must obtain a coding notice from the Revenue Service showing their tax-free balance and social insurance registration number. The employer is the party with whom the worker has contracted; where one person supplies labour, engages their own subcontractors, and receives payment for all the work, that person is treated as the employer.

Controlling directorsCopy link to section

Individuals employed by, and with substantial control over, a limited company are classified as employed persons for contribution purposes from 1 January 2025. Those who wished to remain self-employed could elect to do so for a further five years, provided the Revenue Service received the election by 31 December 2024.

Cross-border and non-Guernsey workersCopy link to section

A non-Guernsey business has no legal obligation to register under ETI, though the Revenue Service recommends it. The authority cannot enforce employer social security contributions against an overseas business, but non-payment can damage the employee's contribution record and entitlement to pension and other benefits. Where the employer agrees, the employee may run their own payroll and ETI submissions.

• Reciprocal agreements with some jurisdictions let a person on temporary secondment keep contributing in their home country.
• Where a non-resident employee works on the island for five days or fewer in a calendar month, the employer need not calculate and remit Guernsey tax (a concessionary treatment).
• Service companies that supply individuals who would otherwise be employees fall under special provisions; consult Statement of Practice C43 – Service Companies.

Compliance, Record-Keeping, and Penalties for Late or Incorrect Payroll RemittanceCopy link to section

Getting remittance wrong carries cost. Failure to remit correctly leads to a surcharge, interest, or penalties, and failure to enrol or contribute to the secondary pension scheme triggers penalties together with back-payment obligations.

Late filing of an income tax return draws an automatic penalty of £100, followed by a daily charge of £10 for each day the return stays outstanding. For a taxpayer whose income falls below the personal allowance, the total penalty is capped at £50 once the return is eventually filed. A penalty may be appealed within 30 days of the penalty order, on grounds such as a life-threatening illness that genuinely prevented filing.

Employers must issue payslips showing gross pay, deductions, and net pay. Payroll records should be kept in sufficient detail to evidence compliance for any Revenue Service enquiry or assessment, and the Debt Management section of the Revenue Service pursues unpaid amounts, taking court action where needed.

Outlook: Phased Rate Increases and the Future of Guernsey Payroll ContributionsCopy link to section

Payroll costs are set to climb steadily rather than sharply. For Class 1 contributors, the rate paid into the Insurance Fund will rise by 0.1% each for employer and employee, a combined 0.2% per year, for ten years. A separate increase of 0.1% per year for four years applies to the Long-term Care Insurance Fund for employees, the self-employed, and the non-employed. The States review these rates annually against the island's economic circumstances.

Secondary pension contributions follow their own upward path. Under a minimum-contribution scheme such as Your Island Pension, employee contributions phase up to 6.5% and employer contributions to 3.5% over the eight-year glide path. The Carey Olsen tax briefing confirms the 2026 rates and the pension trajectory.

One broader change sits on the horizon, though it is not a payroll measure. The 2025 Budget included a proposal to introduce a goods and services tax from 2027; should it proceed, it would reshape the island's tax base but would not alter the payroll obligations described here.

ConclusionCopy link to section

For a foreign business owner, the real weight of Guernsey's payroll framework sits not in the headline contribution rates but in the operational architecture surrounding them: quarterly remittance cycles, ETI deduction mechanics, and category-specific rules for controlling directors and cross-border workers that can quietly misclassify a workforce if left unexamined. The phased rate increases already signalled for coming years mean that a cost model built on today's figures will need revisiting, making that forward-looking adjustment the single most concrete action to take before committing to or scaling a Guernsey payroll.
