Running payroll in Jersey is not the UK system with different logos. The island has its own income tax collection method, its own contributions scheme, and a single combined monthly return instead of separate PAYE and National Insurance filings. Get the moving parts straight once and the monthly cycle becomes routine.
Income tax: the ITIS effective rate
Jersey collects employee income tax as people earn, through the Income Tax Instalment System. Revenue Jersey issues each employee an effective rate — a single percentage the employer deducts from gross pay. The rate reflects that person's own tax position and allowances, so two people on the same salary can carry different rates. New starters without a rate are deducted at a default rate until Revenue Jersey issues theirs.
The effective rate is recalculated once a year. When new rates land, apply them from the date Revenue Jersey specifies — using last year's rate understates the deduction and leaves the employee with a bill.
Social Security on both sides
Both the employer and the employee pay monthly Class 1 Social Security on earnings up to a monthly ceiling. As a rule of thumb the employer pays around 6.5% and the employee around 6%, but the exact rates and the ceiling are set each year, so confirm the current figures on gov.je before you run a period. The employee's share is deducted from gross pay; the employer's share is a cost on top of the wage.
The monthly Combined Employer Return
ITIS and Social Security are reported together on the Combined Employer Return, filed to Revenue Jersey every month with the payment. Miss it and penalties follow — this single deadline causes more employer trouble than any other part of the system. Diarise it, and reconcile the figures to your payroll records before you submit.
What an employee really costs
Owners often budget the salary and forget the employer's Social Security sitting on top. Here is an illustrative month for someone on £3,000 gross, using round rate figures for clarity — check the live rates before relying on the numbers.
| Line | Amount | Who bears it |
|---|---|---|
| Gross wage | £3,000 | — |
| ITIS income tax (illustrative 14%) | −£420 | Employee |
| Employee Social Security (≈6%) | −£180 | Employee |
| Employee take-home | £2,400 | — |
| Employer Social Security (≈6.5%) | +£195 | Employer |
| Total employer cost | £3,195 | — |
The lesson holds whatever the exact rates: the wage is roughly 94% of your payroll cost, and the employer contribution is the part that surprises first-time employers. Our guide to hiring your first employee works the budget through in full.
Minimum wage and holiday
Jersey sets its own minimum wage each year through the States of Jersey — it is not the UK figure. Employees also accrue paid holiday under Jersey employment law. Both feed your payroll cost, so build them in before you agree a salary. The detail sits in paying staff under Jersey law.
Run it yourself, or hand it over
Small employers have three routes: a spreadsheet (workable for one or two staff who know the rules), payroll software that handles Jersey rates, or outsourcing to a local bookkeeper who files the return for you. As headcount grows, the monthly return and year-end reconciliation are where mistakes cost real money.
We run Jersey payroll end to end — payslips, the Combined Employer Return, Social Security and year-end — for a fixed monthly fee. See our payroll service.
Common questions
How does payroll work in Jersey?
You deduct income tax through ITIS at the employee's effective rate, deduct their Social Security, add the employer's Social Security, and report it all on one monthly Combined Employer Return. There is no separate PAYE and National Insurance.
What is the Combined Employer Return?
The single monthly filing to Revenue Jersey covering both ITIS and Social Security for all employees, submitted with payment. It is the deadline most employers miss.
How much does an employee cost an employer?
The gross wage plus the employer's Social Security on top — roughly 6.5% of earnings up to the monthly ceiling. ITIS and the employee's Social Security come out of the gross, not on top.
Do I need payroll software?
Not strictly, but it reduces errors on the monthly return if it handles Jersey ITIS rates and Social Security correctly. Many small employers outsource payroll instead.
