Unpaid leave and sabbaticals in Ireland
Reviewed by Mellow Editorial Team, HR & payroll content team
Unpaid leave and sabbaticals in Ireland have no single statutory definition — they are arrangements agreed between employer and employee, outside the automatic entitlements set by employment law. That means the terms, duration and conditions are largely up to you to set.
What unpaid leave actually is
Unpaid leave is any period of absence from work that the employer agrees to and that is not covered by a statutory entitlement (such as annual leave or maternity leave). A sabbatical is simply a longer, more structured version of the same thing — typically used for personal development, travel, further education or extended rest.
Neither term appears in Irish employment legislation as a stand-alone right. An employee cannot demand unpaid leave or a sabbatical unless your employment contracts or company policy already promise it, or unless a specific statutory scheme applies (see below).
Statutory schemes that overlap
Several statutory entitlements do provide for unpaid or partially unpaid time away from work. These are not the same as a general sabbatical, but they are worth keeping separate in your mind:
- Parental leave — up to 26 weeks of unpaid leave per parent, per child, available until the child turns 12.
- Carer's leave — between 13 and 104 weeks of unpaid leave to provide full-time care to a person who needs it.
- Force majeure leave — a small number of paid days for urgent family emergencies; this is distinct from extended unpaid leave.
- Adoptive leave — statutory unpaid additional adoptive leave exists alongside the paid core period.
These rights exist in law. An employee qualifies for them once they meet the eligibility criteria, regardless of what your policy says. Unpaid sabbaticals sit outside all of these.
How to structure an unpaid leave policy
Because there is no legal template, a written policy is your best protection — for both sides. A clear policy removes ambiguity and reduces the risk of disputes about whether the arrangement was ever agreed.
Key points to address in a policy or individual agreement:
Eligibility. Many employers require a minimum period of continuous service — commonly one or two years — before an employee can apply.
Duration. Set a minimum and maximum. A few weeks is common for personal reasons; three to twelve months is typical for sabbaticals.
Approval process. State clearly that unpaid leave is discretionary, that it requires written approval, and who has authority to grant it. This matters because if you grant it routinely, it may become an implied contractual right over time.
Notice requirements. Require the employee to give reasonable written notice of the request and a confirmed return date before they leave.
Status during the leave. The employment contract continues during unpaid leave. That means the employee retains continuity of service, which counts towards redundancy entitlements. However, they are not earning, so no payroll submissions are needed while they receive nothing — though you should still check with Revenue if any payments (such as a company car benefit) continue.
Annual leave accrual. Employees do not accrue statutory annual leave during unpaid leave under the Organisation of Working Time Act 1997. Make this explicit in your agreement so there is no expectation of four weeks of accrued leave on return.
Pension and benefits. Pension contributions — particularly relevant as My Future Fund auto-enrolment rolls out from 2026 — are tied to earnings. No pay means no contributions from either party under that scheme during the leave. Review any other benefits (health insurance, income protection) to establish whether they continue, lapse or must be paid privately by the employee.
Payroll and tax considerations
No pay means no payroll obligation for the period. You do not submit a real-time payroll file to Revenue via ROS for a pay period in which the employee receives nothing. When the employee returns to work, their payroll resumes as normal from the first payday.
If the employee returns part-way through a tax year, their cumulative tax credits and cut-off points apply as normal under Ireland's PAYE system. Because Ireland uses tax credits rather than a personal allowance, the employee may find they have unused credits from the unpaid period — these carry forward within the year and reduce their tax when earnings resume. Revenue manages this automatically through the cumulative basis; you just run payroll correctly on return.
One administrative point: confirm with the employee before they leave whether they want to use any remaining annual leave entitlement immediately before the unpaid period starts. This is common and avoids any confusion about the leave year.
Handling the return
Put the return date in writing before the employee leaves. If their role is being covered, make clear to the cover arrangement that it is temporary. If the employee wants to extend their leave, treat that as a new request requiring fresh approval — do not let extensions drift informally, as this creates ambiguity about whether the employment relationship has changed.
On return, confirm in writing that they have come back to the same role on the same terms. This protects both parties if questions arise later about continuity or any changes made during their absence.
