Designing a bonus scheme in Ireland
Reviewed by Mellow Editorial Team, HR & payroll content team
Paying a bonus in Ireland is straightforward in principle — you pay it through payroll, and it is taxed as employment income — but designing a scheme that is fair, motivating and legally sound takes more thought than simply picking a number.
Bonuses are fully taxable employment income
Before setting amounts, understand the tax reality your employees will face. A bonus is subject to income tax, USC and employee PRSI in the same way as salary.
For a standard PAYE employee on a middle income, income tax applies at 20% up to roughly €44,000 of annual earnings, and 40% on anything above that. USC is applied in bands — 0.5%, 2%, 3% and 8% — depending on total annual earnings. Employee PRSI runs at approximately 4.1% under Class A.
This means a higher-earning employee receiving a €5,000 bonus could lose more than half of it to deductions. You should communicate this to staff before the scheme goes live. Employees who expect a net amount equivalent to the gross figure will be disappointed, and that disappointment can undermine the motivational effect you were trying to create.
Employer PRSI (approximately 11.15% under Class A) also applies on top of the gross bonus. Factor this into your total cost calculations when budgeting the scheme.
Decide what behaviour or outcome the bonus should reward
A bonus scheme with vague criteria ("good performance", "effort") will create disputes and inconsistency. Before writing any numbers, answer two questions: what specific outcomes justify a payout, and how will you measure them?
Common structures include:
Individual performance bonuses. Tied to targets specific to each role — sales figures, project delivery milestones, customer satisfaction scores. Clear and directly motivating, but require objective measurement to be fair.
Company or team profit share. A pool funded by a percentage of profit above a threshold, distributed across staff. Builds a shared interest in the business result, but employees can feel the outcome is outside their control.
Discretionary bonuses. Paid at management's discretion, with no formal entitlement. These are flexible, but if discretion is exercised inconsistently, you risk claims of discrimination or unfair treatment. Document your reasoning each time.
Retention or sign-on bonuses. Paid to keep key staff or attract hires. Often include a clawback clause requiring repayment if the employee leaves within a set period. Any clawback clause must be clearly documented and ideally acknowledged in writing by the employee before the bonus is paid.
Put the scheme in writing
A bonus scheme does not need to be elaborate, but it must be documented. At a minimum, your written policy should cover:
- the eligibility criteria (who qualifies, minimum tenure requirements, whether fixed-term or part-time staff are included)
- the basis of calculation
- when it is paid
- whether it is discretionary or contractual
- any conditions that can cause forfeiture (such as being under a performance improvement plan or having resigned)
Once a bonus is paid regularly over several years without any qualifying conditions, employees may argue it has become an implied contractual entitlement. If you intend the scheme to remain fully discretionary, state that clearly in writing and review whether your practice matches that intention.
Part-time employees are entitled to pro-rated treatment under Irish employment law. Excluding them entirely from a scheme will require justification.
Running bonuses through payroll correctly
Bonuses must be processed through your payroll system and reported to Revenue on or before the date of payment, as part of Ireland's real-time reporting requirements. You cannot pay a bonus outside of payroll and settle the tax separately later — the submission and the payment must align.
If you run payroll monthly but want to pay a bonus mid-cycle, you will need to run an additional payroll run for that period. This is operationally simple with most modern payroll software, but it is worth confirming the process with your payroll provider before you commit to a payment date publicly.
How Mellow runs payroll across six countries on one platform gives a sense of how real-time reporting works in practice across different jurisdictions, including Ireland.
Common mistakes to avoid
Promising before budgeting. Announcing a scheme before you have confirmed the funding model is a common error. If the business cannot afford the payout, you face either a broken promise or a financial strain.
No cap. Uncapped commission or performance schemes can produce unexpected liabilities. Consider whether a maximum payout per employee per period is appropriate for your model.
Ignoring pension implications. From 2026, Ireland's auto-enrolment pension scheme (My Future Fund) is being introduced. Depending on how pensionable pay is defined under those rules, bonus payments may affect both employer and employee contribution calculations. Check how your scheme treats bonuses when that framework is in place.
Inconsistent application across a team. If managers in different departments apply the same scheme with different standards, you will create internal inequity and potential legal exposure. Build a review step into the process.
