Contractual retirement ages in Ireland: what the new 2025 Act means for employers

Contractual retirement ages have been under pressure for some time – but from 29 June 2026, employers in Ireland face a clearer legal framework for managing retirement ages below the State pension age. 

The Employment (Contractual Retirement Ages) Act 2025 is now in force, introducing a consent-based framework for retirement in Ireland. This is a meaningful change in how retirement is approached at a legal level. It creates a defined process that employers must follow and gives employees a much clearer voice in determining when they leave the workforce.  

For many organisations, this means that long-standing retirement clauses can no longer be relied upon in the same way. It may also require employers to review how retirement decisions fit into wider workforce management, planning and people processes. 

At the heart of the new law is a simple but significant principle: employees cannot be required to retire before the State pension age unless they agree to do so. 

Where a contract sets a retirement age below 66, employees now have the right to refuse that age and indicate that they wish to remain in employment. This introduces a fundamental shift in control. Instead of retirement being triggered automatically by a contract, it becomes a decision that involves the employee’s consent. 

This does not mean that employees must stay on, or that retirement ages disappear entirely. Rather, it creates a more balanced position. Employees can still choose to retire at the contractual age, but they are no longer obliged to do so if they would prefer to continue working. 

For a broader look at how employers can support employees through retirement, see our guide to helping employees transition smoothly into retirement. 

The legislation also introduces a structured process that governs how these situations are handled in practice. 

An employee who does not wish to retire must notify their employer in writing within the required period before reaching their contractual retirement age. This is more than an informal conversation; it is a formal step that triggers a legal obligation for the employer. 

Once that notification is received, the employer must provide a written response setting out its reasoning. The response should clearly state whether the employee will be allowed to continue working or whether the employer intends to rely on the contractual retirement age. 

This requirement brings a new level of transparency to decision making. It ensures that retirement is not treated as an automatic outcome, but as a process that is considered, documented and open to scrutiny. 

Employers can still seek to enforce a retirement age, but only where they can stand over the reasoning for doing so. Employers must be able to show that retirement at a particular age is linked to a legitimate business aim and that the approach taken is appropriate and necessary. However, the introduction of the notification and response process makes this requirement more immediate and practical. 

Rather than relying on general policy, employers are now expected to apply this test in response to individual cases. This means that justification must be clearly explained, evidenced and tailored to the circumstances, rather than assumed as a given. 

In many cases, this will require a stronger link between policy and real-world application than may have been needed in the past. 

This is also part of a wider employee lifecycle challenge, from onboarding through to retirement, where consistency, documentation and manager confidence all matter. 

Another important feature of the legislation is the introduction of enforcement measures and potential penalties. 

If an employer fails to meet its obligations under the Act, including failing to provide a reasoned written response without reasonable cause, this may constitute an offence. This can result in financial penalties and, in certain circumstances, consequences for individuals within the organisation as well as for the organisation itself. 

This marks a clear shift in how retirement policy is viewed. It is no longer simply a matter of best practice or internal HR policy. It now carries a level of legal accountability that employers need to recognise and plan for. 

Alongside the legislation, an updated Code of Practice on Longer Working has also come into effect. This provides practical guidance on how employers and employees should engage in the period leading up to retirement.  

The Code encourages early and meaningful dialogue, helping to ensure that expectations are clear on both sides. It recognises that employees may wish to continue working beyond their contractual retirement age and sets out principles for handling these requests in a fair and structured way. 

Importantly, the Code also reflects the distinction between employees below the State pension age and those aged 66 and over, acknowledging that different considerations may apply in each case. 

These legal changes are part of a broader shift in how retirement is experienced in Ireland. 

The State pension age remains 66, and the new framework effectively strengthens the link between employment practices and that benchmark. In many organisations, contractual retirement ages of 65 have been common, but these are now more likely to be challenged where they fall below the pensionable age.  

At the same time, changing workforce dynamics are playing a role. People are working longer, and many organisations are seeking to retain experienced employees. This creates an environment where flexibility around retirement is not just a legal requirement, but a practical advantage. 

In practice, this means employers should move from a passive retirement clause to an active process. Policies, contracts, manager guidance and record-keeping all need to work together so that requests are handled consistently and decisions can be explained if challenged. 

For employers, the immediate priority is to understand how their current arrangements align with the new legislation. 

Contracts that specify a retirement age below 66 should be reviewed, along with the processes used to manage retirement discussions. It is particularly important to ensure that there is a clear and consistent approach to handling employee notifications and providing reasoned responses. 

There is also a growing need to support managers in this area. Retirement conversations are becoming more nuanced, and the way they are handled can have a direct impact on both compliance and employee trust. 

Taking time now to strengthen these processes can help reduce risk and create a more consistent experience across the organisation. 

A useful starting point is to check whether your organisation has a clear retirement policy, contracts that reflect current legal requirements, a documented notification process, guidance for managers, and a consistent way to record decisions and the reasons behind them. 

While the legislation introduces new obligations, it also offers a clear opportunity for organisations to take stock. 

Reviewing retirement policies in light of these changes allows employers to align with both legal requirements and evolving workforce expectations. It also provides a chance to bring greater clarity and consistency to an area that has often relied on historic practice. 

As this new framework takes effect, a proactive approach will go a long way in ensuring that retirement policies are fit for the future.
