The true cost of hiring an employee in Ireland
Reviewed by Mellow Editorial Team, HR & payroll content team
Hiring an employee in Ireland costs significantly more than their gross salary. Once you add employer PRSI, any pension contributions, and the administrative obligations that come with employment, the real cost is meaningfully higher than the number on the offer letter.
What sits on top of gross salary
The most immediate additional cost is employer PRSI. For most employees on a standard employment contract, this falls under Class A, where the employer pays 11.15% of gross earnings. That figure applies on top of salary — it is not deducted from the employee's pay.
So if you hire someone at €50,000 gross, your PRSI liability alone adds roughly €5,575 per year. Hire five people at that salary and you are looking at close to €28,000 in employer PRSI before anything else is factored in.
There is no employer liability for income tax or USC — those are employee-side deductions — but employer PRSI is unavoidable and should be built into your budget from day one.
What the employee pays (and why it matters to you)
You are responsible for calculating and deducting the employee's taxes through payroll, so you need to understand how they work even though you are not paying them directly.
Income tax in Ireland uses a credit system rather than a personal allowance. Earnings up to roughly €44,000 (for a single person) are taxed at 20%. Anything above that is taxed at 40%. The employee's actual liability is reduced by tax credits, which Revenue assigns based on individual circumstances. The net result varies by person, so you should not assume a flat deduction figure — always use Revenue's tax credit certificates.
USC (Universal Social Charge) is charged in bands: 0.5%, 2%, 3%, and 8%, applied progressively. Again, this is deducted from the employee, not an employer cost, but you are doing the calculation and making the payment to Revenue.
Employee PRSI under Class A is 4.1% of gross earnings. You deduct this from their pay and remit it to Revenue alongside your own employer PRSI contribution.
The real-time reporting obligation
Ireland operates a real-time payroll reporting system. Every time you run payroll, you must submit a payroll submission to Revenue through ROS on or before the date you pay your employees. There is no end-of-year reconciliation to fall back on — accuracy at the point of payment is the requirement.
This means your payroll process needs to be set up correctly before you make your first payment. Errors are visible to Revenue immediately and correcting them requires amended submissions. The administrative burden is real, particularly for businesses hiring their first employee or scaling quickly.
Pension auto-enrolment from 2026
Ireland is introducing mandatory pension auto-enrolment under the scheme known as My Future Fund, with rollout beginning in 2026. Employers will be required to make contributions on behalf of eligible employees, adding a further direct cost to headcount.
The scheme is being phased in, so contribution rates will start lower and step up over time. If you are planning headcount growth, it is worth factoring in that pension costs are moving from optional to statutory. The exact rates and thresholds will be confirmed as the scheme launches, but the direction of travel is clear: employer pension contributions will become a fixed line in your cost-per-employee calculation.
Other employment costs worth accounting for
Beyond tax and PRSI, there are several costs that employers sometimes underestimate when pricing up a hire:
Annual leave — Employees are entitled to 4 working weeks of paid leave per year as a statutory minimum. This is not additional cost per se, but it means you are paying for time when no work is done. For roles where cover is needed, it may mean overtime or temporary staff.
Recruitment — Agency fees, job board listings, or the internal time spent interviewing and onboarding all have a cost that does not appear on the payroll.
Equipment and workspace — Laptop, software licences, desk, phone — these vary by role but are rarely zero.
Employer's liability insurance — Required once you have employees. Premiums vary by sector and headcount.
Sick pay — Statutory sick pay entitlements exist in Ireland, meaning you may be obliged to pay employees during periods of certified illness. The number of qualifying days has been increasing incrementally, so check the current statutory minimum.
A reasonable working assumption for total employer cost is to take gross salary and add 12–15% just for employer PRSI and basic on-costs, then layer in pension contributions once auto-enrolment applies. For a full picture, you should also cost in the non-payroll items above before signing an offer letter.
