How much does payroll cost in Ireland?
Reviewed by Mellow Editorial Team, HR & payroll content team
Running payroll in Ireland typically costs between €4 and €12 per employee per month if you use a managed payroll bureau or software, though the total cost of employment is dominated by statutory employer contributions — primarily PRSI at 11.15% of gross wages.
What employers actually pay on top of gross salary
Every time you pay an employee, your real cost is higher than the salary figure in the contract. The main statutory add-on is employer PRSI at 11.15% of gross pay for Class A employees, which covers the vast majority of full-time workers. There is no employer contribution to USC — that is deducted solely from the employee's pay.
So if you hire someone on €40,000 a year, your PRSI liability alone adds roughly €4,460 on top, bringing the employment cost closer to €44,460 before any other overhead.
If your business offers occupational pension contributions, those are an additional cost on top of statutory PRSI. Pension auto-enrolment under the Government's My Future Fund scheme is being introduced from 2026, which will require employer contributions for eligible employees who are enrolled — factor this into your headcount planning now if you have not already.
The cost of payroll administration itself
Separate from statutory costs, you have the cost of actually running payroll — calculating pay, deducting income tax, USC and PRSI correctly, filing with Revenue, and issuing payslips.
Your main options and their typical cost ranges:
In-house payroll. You use payroll software and a member of staff handles submissions. Software licences for small Irish businesses typically run from around €10 to €30 per month for a small headcount, plus staff time. The hidden cost here is the expertise required — Ireland's payroll rules, including real-time reporting obligations and tax credit management, are not simple.
Payroll bureau. An accountant or specialist bureau processes payroll on your behalf. Expect to pay roughly €4–€12 per employee per month, sometimes with a minimum monthly fee of €50–€100. Some bureaus charge per payrun rather than per head. Prices vary significantly depending on whether you are running weekly, fortnightly or monthly payroll, and how much complexity is involved (directors, benefits in kind, share schemes).
Integrated global payroll platforms. If you have employees in multiple countries, per-employee pricing is often bundled into a broader service. This can be cost-effective relative to managing separate local bureaus. How Mellow runs payroll across six countries on one platform gives a sense of how that works in practice.
Revenue reporting and compliance costs
Ireland operates a real-time payroll reporting system. You must submit a payroll submission to Revenue via ROS on or before each payday — not monthly, not quarterly, but every single time you pay someone. This is non-negotiable and errors or late filings can trigger penalties.
This real-time requirement means payroll is not something you can batch up and deal with at the end of the month. It demands either a reliable software integration or a bureau that handles submissions on your behalf. The compliance burden is a genuine cost driver, particularly for businesses without a dedicated finance function.
Year-end obligations include issuing P60 equivalents and ensuring all Revenue records reconcile. If you have employees with complex tax situations — multiple employments, benefits in kind, or irregular hours — the administration time increases accordingly.
What affects your payroll costs most
A few factors push costs up significantly:
Pay frequency. Weekly payroll costs more to administer than monthly. If you pay weekly and use a bureau, you may be charged per payrun, which adds up.
Workforce complexity. Directors, part-time workers, employees with multiple tax credits, or those on irregular hours all add processing time. Benefits in kind (company cars, health insurance) require additional calculations and potentially P11D-equivalent reporting.
Headcount changes. Starters and leavers require more work than a stable payroll. High turnover means more Revenue notifications, more tax credit certificate requests, and more scope for error.
Payroll errors. Correcting a payroll mistake in Ireland is not straightforward — it often requires amended submissions to Revenue and can affect an employee's tax position. Prevention through good systems or professional support is genuinely cheaper than remediation.
A realistic total cost model
For a small Irish employer with 10 employees on monthly payroll, a reasonable annual cost breakdown might look like this:
- Bureau or software fees: €600–€1,500 per year
- Employer PRSI across the team: depends entirely on salary levels, but at average wages this is a very significant six-figure liability for a full team
- Internal staff time: variable, but even a "simple" monthly payroll takes several hours when you include checking, querying, and filing
The statutory employer PRSI contribution will almost always dwarf the administrative cost of running payroll. That is the figure to model carefully when budgeting for a new hire.
