Salary sacrifice arrangements in Ireland
Reviewed by Mellow Editorial Team, HR & payroll content team
Salary sacrifice in Ireland lets an employer and employee agree to reduce the employee's gross pay in exchange for a non-cash benefit, reducing the PRSI and USC both parties pay on that portion of salary. The tax treatment depends entirely on which benefit is being sacrificed for — not all benefits qualify.
How salary sacrifice works in Ireland
The employee formally agrees, in writing, to take a lower gross salary. The employer provides a specified benefit instead. Because the benefit sits outside cash pay, it may attract more favourable tax treatment than the equivalent salary would.
The key word is "may." Revenue's position is clear: salary sacrifice only produces a tax or PRSI saving if the benefit being exchanged is either exempt from income tax under Irish legislation, or qualifies for a specific Revenue concession. If the benefit is not exempt, the employee is still taxed on the original, higher salary — so the arrangement achieves nothing.
Which benefits qualify
The most common salary sacrifice arrangements Revenue accepts in Ireland are:
Travel passes. An employer-purchased annual or monthly public transport pass is exempt from income tax, USC and PRSI. Sacrificing salary to fund a travel pass is one of the cleanest arrangements available, because the exemption is statutory and well-established.
Employer pension contributions. Employees can sacrifice salary so the employer makes a higher pension contribution on their behalf. Employer pension contributions are not subject to income tax, USC or PRSI — so both parties benefit. This is widely used and Revenue-compliant when structured correctly.
Cycle to Work scheme. Employers can provide a bicycle and safety equipment up to a certain value under the Cycle to Work scheme. Salary sacrifice is a common mechanism here. The benefit is exempt from income tax, USC and PRSI.
Other approved benefits. Some employers use salary sacrifice for employer-provided childcare, remote working equipment, or other Revenue-approved benefits. Each needs to be assessed individually against current Revenue guidance.
Benefits that are not tax-exempt — such as cash bonuses restructured as "benefits" — do not produce a saving. Revenue will look through the arrangement and tax the employee as though they received the salary.
The employer process, step by step
1. Confirm the benefit qualifies. Before doing anything else, confirm in writing — ideally with your tax adviser or payroll specialist — that the specific benefit is exempt or concessional under current Revenue rules.
2. Get a written salary sacrifice agreement. The employee's contract of employment must reflect the reduced salary. A side letter or addendum is not enough on its own; the contractual gross salary must actually change. Verbal arrangements carry no legal weight and will not satisfy Revenue in an audit.
3. Update payroll. The employee's gross pay for payroll purposes is the reduced figure. Income tax at 20% or 40% depending on where they sit relative to the standard rate band, USC at the applicable banded rates (0.5%, 2%, 3%, or 8%), and PRSI at 4.1% employee / 11.15% employer are all calculated on the lower gross. The employer funds the benefit separately.
4. Report correctly to Revenue. Ireland operates real-time payroll reporting. Every payroll run must be submitted to Revenue via ROS on or before the date employees are paid. The payroll submission should show the actual gross (post-sacrifice) salary, not the original figure. Getting this wrong — for example, reporting the pre-sacrifice salary but paying tax on the post-sacrifice figure — creates a discrepancy Revenue can flag.
5. Keep records. Retain the signed salary sacrifice agreement, payroll records showing the reduced gross, and evidence of the benefit provided (receipts, pass purchase records, pension schedules). Revenue can request these during a PAYE audit.
Risks and common mistakes
Salary sacrifice reduces an employee's gross pay. That matters beyond tax. Statutory entitlements based on gross pay — including certain social welfare benefits and entitlements that reference reckonable earnings — may be affected. Employees should understand this before signing.
Pension auto-enrolment under "My Future Fund" is being introduced from 2026. Employer and employee contributions under that scheme are calculated on gross pay, so the interaction between auto-enrolment and salary sacrifice arrangements will need careful attention as implementation progresses.
A common employer mistake is treating salary sacrifice informally — agreeing it verbally or applying it in payroll without a proper contract amendment. If Revenue audits and there is no written agreement, they will likely disallow the arrangement entirely and assess tax on the original salary, with potential interest and penalties.
Minimum wage considerations
A salary sacrifice arrangement cannot reduce an employee's effective cash pay below the national minimum wage. Employers must check that the post-sacrifice cash salary still meets the minimum wage obligation for the hours worked. If it does not, the sacrifice must be limited so that the cash element remains compliant.
