The salary is only part of the cost
Your real outlay for an employee includes employer Social Security on top of the wage, plus the time and systems to run payroll, deduct ITIS and stay compliant. Budget for the full picture before you make the offer.
Hiring your first employee is one of the most exciting steps a Jersey business can take. It means demand has outgrown what you can deliver alone — a genuine sign of momentum. But it also moves you from being self-employed to being an employer, and that shift carries real financial and legal responsibilities you need to set up properly from the start.
The good news is that Jersey's employer obligations are clearly defined and entirely manageable once you know the moving parts. You will need to register as an employer, operate the Income Tax Instalment System (ITIS) to deduct tax from wages, run a compliant payroll, understand the basics of Jersey employment law, and budget honestly for the full cost of the hire. Let us take each in turn.
Register as an Employer for Social Security
Your first formal step is registering as an employer. In Jersey, everyone who works contributes to Social Security, and once you employ staff you become responsible for handling Class 1 contributions — both the employer's share and the employee's share deducted from their pay.
The employer cost on top of salary:
Employer Class 1 Social Security contributions currently fall around 6.5% of earnings, with the employee paying around 6%, charged monthly. Both the rates and the earnings ceiling are reviewed annually, so always confirm the current figures on gov.je before you budget.
Register as an employer with the relevant Jersey authority before your new starter's first payday. Doing it early means your contribution schedule is in place from day one and you avoid arrears or last-minute scrambles. Remember that as a self-employed owner you will have been paying Class 2 contributions yourself — becoming an employer adds the Class 1 obligation on top.
Understanding ITIS Deductions
Jersey collects income tax from employees through the Income Tax Instalment System, known as ITIS. Rather than employees paying their tax in a lump sum, you as the employer deduct it from their wages each pay period and pass it to Revenue Jersey. The income tax standard rate in Jersey is 20%.
In practice, ITIS works like this:
- Revenue Jersey issues an effective rate for each employee, telling you what percentage to deduct
- You apply that rate to the employee's earnings each pay period
- You withhold the ITIS amount from their pay alongside their Social Security contribution
- You pay the deducted tax over to Revenue Jersey in line with the required schedule
The key thing to grasp is that ITIS deductions are not your money — you are collecting tax on Revenue Jersey's behalf and holding it briefly before paying it over. Never treat it as available cash flow. A reliable payroll process keeps these deductions accurate and paid on time, which is exactly where a good system or bookkeeper earns its keep.
Setting Up Payroll Properly
Payroll is where employer registration, ITIS and Social Security all come together each pay period. Getting it right means your employee is paid correctly and on time, your deductions are accurate, and your obligations to Revenue Jersey and Social Security are met without fuss.
A sound first-hire payroll setup covers the following:
Gather your employee's details
Collect the information you need to pay them correctly and apply the right ITIS effective rate and Social Security treatment from their very first payslip.
Choose how you'll run payroll
Decide between payroll software and outsourcing to a bookkeeper. For a first hire, many owners prefer to outsource so that ITIS, Social Security and payslips are handled accurately while they focus on the business.
Calculate gross to net each period
From the gross wage, deduct ITIS and the employee's Social Security, then add the employer's Social Security as a separate cost to your business. Issue a clear payslip showing the breakdown.
Pay and report on schedule
Pay your employee, then pay the deducted ITIS and the Social Security contributions over to the relevant authorities by their deadlines. Keep every payroll record as part of your six-year accounting trail.
Employment Law Basics
Becoming an employer brings legal duties alongside the financial ones. Jersey has its own employment law framework, distinct from the UK, covering the rights and protections your employee is entitled to. You do not need to be a legal expert, but you do need to meet the core obligations from the outset.
Areas to make sure you understand before hiring include:
- Providing a written statement of the employee's terms of employment
- Meeting minimum standards on pay, working time, holiday and rest
- Following fair process around discipline, grievances and any dismissal
- Confirming the person is permitted to take up the role under Jersey's rules
Employment law detail and minimum standards change over time, so confirm the current requirements on gov.je and take proper advice for anything significant — particularly contracts and any dispute. Getting the basics right at the start, especially a clear written contract, prevents most problems before they arise.
Budgeting for the Real Cost of a Hire
The headline salary is never the full story. To make a confident hiring decision, map out the complete cost so you know the figure your business actually has to support each month.
| Cost Element | What It Covers | Who Bears It |
|---|---|---|
| Gross salary | The agreed wage before deductions | Employer |
| Employer Social Security | Around 6.5% on top of the wage (verify) | Employer |
| Employee Social Security | Around 6%, deducted from pay | Employee |
| ITIS | Income tax deducted at the effective rate | Employee |
| Payroll & admin | Software or bookkeeping support | Employer |
| Other costs | Equipment, space, training, recruitment | Employer |
Social Security rates and the earnings ceiling are reviewed annually — confirm the current figures on gov.je before finalising your budget.
Frequently Asked Questions
What does it actually cost me to employ someone in Jersey beyond their salary?
On top of the gross wage, you pay the employer's share of Social Security — currently around 6.5% of earnings, though the rate and ceiling are reviewed annually. You also bear payroll and admin costs and any equipment, space or training the role needs. The employee's own Social Security and ITIS come out of their pay rather than costing you extra, but you must deduct and pay them over correctly.
Do I have to deduct ITIS from my first employee's wages?
Yes. ITIS is how Jersey collects income tax from employees. Revenue Jersey provides an effective rate for each employee, and you deduct that percentage from their pay each period and pass it to Revenue Jersey. The income tax standard rate is 20%. The deducted tax is never your money — you are simply collecting it on Revenue Jersey's behalf, so keep it separate from your working cash flow.
When do I need to register as an employer?
Register as an employer before your new starter's first payday so your Social Security and ITIS obligations are in place from their very first payslip. Doing it early avoids arrears and last-minute problems. Remember that as a self-employed owner you will already be paying Class 2 contributions personally — employing staff adds the Class 1 employer obligation on top.
Is Jersey employment law the same as the UK's?
No. Jersey has its own employment law framework, separate from the UK, covering contracts, minimum standards, working time, holiday and fair process around discipline and dismissal. The details and minimum standards change over time, so confirm the current position on gov.je and take professional advice for contracts and any significant employment issue.
