Directive (EU) 2023/970 does not prescribe one universal employer retention schedule for every pay record, but its enforcement rules make reliable documentation important. Employers should be able to reconstruct how pay was set, what criteria were used, what information was supplied, how worker categories were defined, how reports were calculated and how complaints were handled. Retention periods must be aligned with national employment, limitation and data-protection rules rather than based on an invented EU-wide number.

Record Keeping Is an Evidence Control, Not Just Administration
Article 18 can place the burden on an employer to prove that there was no pay discrimination, and Article 19 allows relevant evidence within the respondent's control to be ordered for disclosure. Those rules make documentation central to enforcement. A pay decision that was lawful but cannot be reconstructed years later can be harder to explain. Employers should therefore design records around the decisions and transparency duties most likely to require later evidence.
Retain the Basis for Individual Pay Decisions
Useful records include approved ranges, starting-pay decisions, job grades, objective criteria, performance evidence, market data actually relied on, collective-agreement provisions and documented exceptions. The purpose is to show not only what the worker was paid but why. A generic policy that lists possible factors is weaker evidence than a contemporaneous record identifying the factor applied in the specific decision.
Keep Worker Information Request Records
Employers should log the date of each request under Article 7, the worker category used, the information supplied, any clarification requested and the response date. The Directive requires annual notification of the right and a response within a reasonable period and no later than two months. These records help demonstrate that the information process was actually implemented and can be important if Article 18(2) burden-of-proof consequences are later considered.
Reporting and Joint Assessment Records Need Reproducibility
For employers subject to Article 9 reporting, source data, formulas, worker-category methodology, management confirmation and consultation records should be retained in a controlled form. If Article 10 triggers a joint pay assessment, the analysis, representative involvement, reasons for differences and corrective measures should also be documented. The goal is to enable a later reviewer to reproduce the figures and understand the decisions made from them.
Complaint and Investigation Records Need Careful Governance
When a worker raises an equal-pay concern, employers should preserve the complaint, relevant pay evidence, investigation steps and outcome. Access should be limited appropriately because pay and complaint records can contain sensitive personal information. Records should distinguish factual findings from legal advice where applicable and should follow the organisation's privilege and confidentiality rules. Consistent case files reduce delay and make it easier to show how the employer responded.
Retention Periods Must Be Set by Applicable Law and Risk
The Directive does not provide a single number of years for retaining every record. Article 21 does, however, set minimum safeguards for claim limitation periods, which means potentially relevant evidence can remain important for years. Retention schedules should be designed with employment law, procedural rules, data-protection principles and the organisation's legitimate evidential needs in mind. Employers should document why categories of records are retained and when they are deleted rather than keeping everything indefinitely.
Frequently Asked Questions
Does the Directive set one retention period for pay records?
No. Employers must determine retention under applicable national employment, procedural and data-protection law.
Why are records especially important under the Directive?
Because burden-of-proof and evidence-disclosure rules can require employers to explain pay decisions and produce relevant evidence.
Should worker information requests be logged?
Yes. A request log helps demonstrate timing, response content and implementation of Article 7 procedures.
