Article 21 of Directive (EU) 2023/970 requires national limitation rules for equal-pay claims to state when the period starts, how long it lasts and when it can be suspended or interrupted. The period cannot begin before the claimant is aware, or can reasonably be expected to be aware, of the infringement, and it cannot be shorter than three years. Member States may provide more favourable rules, including delaying the start while an infringement continues or until the employment relationship ends.
Jurisdiction: European Union
Check national start, duration and interruption rules
The Directive Sets Minimum Standards Rather Than One EU Deadline
There is no single identical filing deadline for every equal-pay claim across the European Union. Article 21 requires Member States to define the start, duration and suspension or interruption of limitation periods, but it sets minimum safeguards that national law must respect. Employers and workers therefore need the national rule for the relevant jurisdiction. A three-year figure should not automatically be treated as the full answer because a Member State can provide a longer period or other more favourable arrangements.
The Clock Cannot Start Before Awareness
A central safeguard is that the limitation period cannot begin before the claimant is aware, or can reasonably be expected to be aware, of the infringement. This is particularly important in pay discrimination because a worker may not know what colleagues earn or how pay criteria were applied. Transparency rights can reveal information that was previously unavailable. The awareness rule therefore prevents a claim from expiring before the worker could realistically recognise that a problem existed.
Member States Can Delay the Start Further
Article 21 allows Member States to decide that limitation periods do not begin while an infringement is ongoing or before the employment contract or relationship ends. This is optional at EU level, so the national legislation must be checked. The possibility matters where an unequal pay practice continues over several years. Employers should not assume that the first disputed pay decision necessarily starts a fixed EU-wide clock.
A Complaint Can Suspend or Interrupt the Period
Member States must ensure that the limitation period is suspended or, depending on national law, interrupted when the claimant takes action by bringing a complaint to the employer or instituting proceedings before a court, directly or through workers' representatives, the labour inspectorate or an equality body. The precise legal effect of suspension versus interruption differs by legal system. Employers should record complaint dates accurately because those dates can have procedural significance.
The Minimum Duration Is Three Years
The Directive states that limitation periods for bringing equal-pay claims cannot be shorter than three years. That is a floor, not a universal maximum. A Member State can use a longer period or maintain more favourable claimant rules. The period should also be read together with the awareness and suspension provisions. A simple policy statement that claims expire three years after a pay decision may therefore be inaccurate in a particular country.
Record Retention Should Reflect Claim Risk
Limitation rules influence how long evidence may remain important. Employers should align retention policies with national employment, privacy and procedural rules so that relevant pay decisions can still be reconstructed when a timely claim is brought. Useful evidence can include pay histories, job evaluation records, criteria, requests, responses and complaint dates. Retaining everything indefinitely is not the answer, but deleting relevant records too early can create avoidable evidential problems.
Frequently Asked Questions
Is the equal-pay limitation period always three years?
No. Three years is the minimum period required by Article 21. Member States may provide longer or more favourable rules.
When does the limitation period start?
It cannot start before the claimant is aware, or can reasonably be expected to be aware, of the infringement.
Can an internal complaint affect the time limit?
Yes. Article 21 requires suspension or interruption, depending on national law, when the claimant takes action by bringing a complaint to the employer.
