Gender Pay Gap Reporting: What the EU Directive Means

The EU Pay Transparency Directive (2023/970/EU) introduces mandatory gender pay gap reporting requirements that go significantly further than any existing national requirement in Europe — or in the United States. For HR teams currently managing UK gender pay gap reporting or France's Index égalité, the EU Directive's eight-metric reporting framework represents a substantial expansion of scope, data collection, and operational complexity. This guide covers what's required, when, and what your team needs to do to prepare.

The EU Directive reporting framework

Unlike the UK's two-metric framework (mean and median gender pay gap), the EU Directive requires reporting on eight distinct metrics:

1. The gender pay gap in base pay by individual pay component
2. The gender pay gap in supplementary/variable pay (bonuses, commissions) by component
3. The gender pay gap in total compensation
4. The proportion of male and female workers receiving supplementary pay
5. The proportion of male and female workers receiving bonus pay
6. The proportion of male and female workers in each pay quartile
7. The gender pay gap by category of worker (using pay grade categories, if applicable)
8. Parental leave uptake rates by gender

Most HR information systems are not configured to produce these metrics out of the box. The data infrastructure work — ensuring all compensation components are tracked by employee ID with gender data, that parental leave is coded correctly by type and gender, that pay quartile assignments are calculated correctly — takes significant lead time. Starting this work in 2026 for 2027 reporting is the minimum viable timeline.

Who must report and when

The Directive sets reporting obligations by employer size:

• 250+ employees: Annual reporting, first cycle covers data from calendar year 2026, to be published by June 2027.
• 150–249 employees: Reporting every three years, first cycle covers data from 2026, to be published by June 2027.
• 100–149 employees: Reporting every three years, first cycle covers data from 2030, to be published by June 2031.
• Under 100 employees: Not required at the EU Directive level, though member states may extend requirements. Belgium and France have indicated they will extend requirements to smaller employers in national transposition.

The 5% gap trigger: joint pay assessment

One of the most operationally significant elements of the Directive is the 5% trigger. If an employer's published gender pay gap in any pay category is 5% or more and the employer cannot objectively justify the gap within six months of publication, a joint pay assessment must be conducted with employee representatives.

The joint pay assessment must: identify the root causes of the gap, engage worker representatives in the analysis process, produce written documentation of the assessment and its findings, and include a concrete remediation plan with timelines. The assessment cannot be completed unilaterally by HR — it requires genuine engagement with employee representatives, which adds a coordination and communication dimension that many organisations are not prepared for.

The practical implication: employers should conduct a preliminary internal pay equity analysis before they're required to publish, so they're not surprised by gaps that trigger mandatory assessments. See our pay equity audit guide for the methodology.

UK vs EU reporting: what changes for employers managing both

UK employers with EU operations — or EU employers with UK subsidiaries — will be managing two distinct gender pay gap reporting frameworks from 2027. Key differences:

• Scope: UK requires employers with 250+ UK employees. EU Directive applies per member state — you may have obligations in Germany and France independently of your UK obligations.
• Metrics: UK requires mean and median gender pay gap (2 metrics). EU Directive requires 8 metrics across multiple pay components.
• Consequences: UK reporting has no direct financial penalties for gaps (the penalty is for non-reporting). EU Directive penalties are set by member states and can be significant — the Netherlands has signalled 1% of annual payroll for repeated violations.
• Mandatory action: UK has no mandatory action for disclosed gaps. EU Directive's 5% trigger creates a mandatory joint pay assessment obligation.

Preparing your data infrastructure

The eight-metric framework requires your HR system to be able to produce, for every employee: the individual components of their total compensation (base, bonus, commission, benefits with cash value), their gender identity (with appropriate privacy protections for self-identification data), their pay category or grade, their parental leave history (type, duration, gender of employee), and their employment start date and level.

Most modern HRIS platforms (Workday, SAP SuccessFactors, BambooHR) can produce this data if configured correctly. The work is in the configuration, data quality audit, and report build — not in acquiring new software. For organisations with legacy HRIS platforms or fragmented data across multiple systems, the timeline for data infrastructure readiness may be longer.

The salary history ban and its connection to pay gap reporting

The EU Directive's salary history ban is directly connected to the pay gap reporting requirement. One of the most common root causes of gender pay gaps is the compounding effect of salary history — women who entered the workforce at lower starting salaries have historically carried those initial anchors forward through their careers. By banning salary history from the hiring process, the Directive aims to interrupt this dynamic at the point of hire. See our EU Directive overview for full details on the salary history ban requirements.
