EU Pay Transparency Directive Belgium: A Compliance Guide

At a Glance

• Status: Deadline missed, two-track split. Belgium did not fully transpose by 7 June 2026. The public sector is partially transposed and in force at regional level. For the federal private sector there is no draft legislation yet. Belgium has requested a six-month extension from the European Commission.

• EU transposition deadline: 7 June 2026 (missed for the private sector)

• Existing framework: One of the EU's longest-established pay transparency regimes, with biennial reporting since 2012

• Reporting threshold: 50+ employees under existing Belgian law; EU Directive thresholds layered on top for larger firms

• Distinctive feature: Pay data filed through the existing Social Balance Sheet (Bilan Social / Sociale Balans) at the National Bank of Belgium

• Reporting cadence: Biennial under existing Belgian law; annual or triennial under the EU Directive depending on headcount

Implementation Status: The Two-Track Transposition

Belgium has had pay transparency reporting embedded in national law since the Pay Gap Act of 2012 (Loonkloofwet / Loi sur l'écart salarial). Combined with CAO nr. 25 / CCT n° 25 (the Collective Bargaining Agreement on equal pay) and the Gender Discrimination Act 2007, Belgium operates one of the longest-established pay transparency regimes in the EU.

According to Pinsent Masons' analysis, Belgium is taking a two-track approach. The two tracks are at very different stages:

• Public sector: partially transposed and in force. The Wallonia-Brussels Federation adopted a decree on 16 May 2024, in effect since 1 January 2025. The Flemish public sector is covered by a separate government decree. These regional decrees largely mirror the Directive.

• Private sector: no draft yet. There is no federal private-sector bill published. The framework is deadlocked in the National Labour Council (Conseil National du Travail / Nationale Arbeidsraad), where employer representatives are pressing for a strict, no-gold-plating transposition, backed by a non-binding Federal Parliament resolution of 26 January 2026. Realising it would miss the deadline, Belgium formally requested a six-month extension from the European Commission on 1 June 2026.

Belgium has one of the lowest gender pay gaps in Europe, with Statbel reporting figures around 5%. This is significantly below the EU average. The EU Directive will nonetheless force more granular transparency onto the existing framework. If you need further information on the wider ramifications of the new EU Directive, see the PayAlign's full Directive guide.

Even though no federal private-sector law is in force, private-sector employers are not insulated from risk. Because the 7 June 2026 deadline has passed, Belgian courts are likely to interpret existing equal-pay law, including the Gender Pay Law of 2012, in line with the Directive. Employees may seek to rely on the Directive's core provisions directly. The eventual federal framework will have to replace the existing generic reporting structure, under which companies with 50 or more workers track pay via the biennial social balance sheet filed with the National Bank, with the Directive's granular 5% joint assessment trigger, reversed burden of proof and pre-interview pay transparency.

The Belgian government has launched the Be-Magic project (Modernisation and Adaptation of Gender-neutral Instruments of Classification) to help companies build gender-neutral job classifications.

Scope and Thresholds

The EU Pay Transparency Directive applies to all Belgian employers in both the public and private sectors. Substantive obligations apply regardless of size. Belgium's existing framework already exceeds the EU Directive minimum on scope.

Belgium is expected to retain the 50-employee threshold for biennial reporting alongside the EU Directive thresholds. For multi-entity groups, the threshold applies at the legal employer level. Confirmation with Belgian legal counsel is recommended.

Key Metrics

The EU Directive requires employers above the threshold to publish:

• Average Hourly Pay: Average gross hourly earnings, split by gender.

• FTE Disparity: A breakdown of pay for full-time vs. part-time employees.

• Remuneration Components: Base pay vs variable and complementary pay.

• Training Hours: The average number of training hours funded by the employer, broken down by gender.

• Level-Based Gaps: Pay differences across different Job Classes (Functieclassificaties).

• Seniority Metric: A calculation showing how "Length of Service" impacts pay for men vs. women.

• Educational Attainment: Pay gaps adjusted for the level of qualification/degree held by the employees.

Belgian employers already capture most of these data points through the existing Pay Gap Act framework. According to Liedekerke's analysis, the 2012 Act and CAO nr. 25 already require gender-classified remuneration analysis. The 2026 reform integrates the EU Directive's metrics directly into the existing Social Balance Sheet (Bilan Social / Sociale Balans) filed with the National Bank of Belgium.

This is materially different from how reporting works elsewhere. Pay data sits inside an existing public filing rather than a standalone report. This allows for a familiar process but it creates greater public visibility.

The EU Directive layers two new methodological requirements on top: reporting broken down by categories of workers performing equal work or work of equal value using the four-factor methodology (skills, effort, responsibility, working conditions) and a formal employee right to information.

The Be-Magic project provides government-backed methodology for the gender-neutral job classification (Functieclassificatie / Classification de fonctions) the EU Directive requires.

Navigating the Ondernemingsraad: The Role of the Social Partners

In Belgium, pay transparency is a social dialogue. The Works Council (Ondernemingsraad / Conseil d'entreprise) is the gatekeeper. The gender pay report must be discussed in the Works Council within three months of the financial year-end. This creates stricter consultation requirements than elsewhere in the EU.

Pay data must be presented in a Works Council-friendly format and the methodology must withstand union scrutiny. Detected pay disparities (Vastgesteld loonverschil) must be addressed through structured dialogue, not unilateral action. When uncorrected gaps persist, an internal mediator (Bemiddelaar / Médiateur) must be appointed. This is a procedural layer that does not exist elsewhere in the EU.

Where Belgium Goes Beyond the EU Directive Minimum

Belgium's existing regime exceeds the EU Directive minimum in several respects.

Lower 50-employee threshold. Belgium has required biennial pay gap reporting for employers with 50+ employees since 2012. The EU Directive minimum is 100.

Social Balance Sheet integration. Pay data is published through an existing public filing rather than a standalone report, making Belgian pay transparency more visible than in most member states.

Mandatory Works Council discussion. The three-month post-year-end discussion requirement is materially stronger than consultation provisions elsewhere.

Internal mediator requirement. Where pay disparities are not corrected, an internal mediator (Bemiddelaar / Médiateur) must be appointed.

Be-Magic government infrastructure. The Be-Magic project provides methodology for gender-neutral job classification.

Pre-employment salary information. Belgium is expected to require salary information before the first interview. This is stricter than the EU baseline.

Penalties and Risks of Non-Compliance

The current Belgian enforcement architecture operates through The Institute for the Equality of Women and Men (Instituut voor de gelijkheid van vrouwen en mannen), the labour inspectorate and the labour courts. The EU Directive (Article 23) requires fines that are effective, proportionate and dissuasive.

Two changes materially shift the litigation risk profile:

1. Reversal of the burden of proof (Inversie van de bewijslast / Renversement de la charge de la preuve). Where an employer fails to meet pay transparency obligations, the employer must prove no discrimination occurred. Combined with the Works Council's strong consultation rights, defensibility of pay decisions in Belgian labour courts will be among the lowest in the EU.

2. Public visibility through the Social Balance Sheet. Pay data sits in a public National Bank filing. Non-compliance is visible to regulators, journalists, investors and competitors.

The right to compensation under Articles 16 and 17 includes full recovery of back pay, lost opportunities and non-material damages with no upper limit.

How PayAlign Helps Irish Employers Prepare

PayAlign is a compliance platform built specifically for the Irish Gender Pay Gap Information Act and the EU Pay Transparency Directive. It takes Irish & EU payroll data through the full compliance workflow without the spreadsheet engineering most employers currently rely on.

The platform handles automated gender pay gap reporting calculations across all 14 mandatory Irish and the EU Directive metrics, category-of-workers reporting, joint pay assessment workflow including documentation, audit-ready data supporting the reversed burden of proof and submission-ready outputs for the centralised public portal.

Frequently Asked Questions

When will Belgium fully implement the EU Pay Transparency Directive?

Belgium is taking a two-track approach. The public sector has been partially transposed at regional level. For the federal private sector there is no draft legislation yet. The framework is deadlocked in the National Labour Council, where employers press for a strict, no-gold-plating transposition. Belgium has requested a six-month extension from the European Commission.

What is the Social Balance Sheet?

The Social Balance Sheet (Bilan Social / Sociale Balans) is a mandatory public filing all Belgian companies submit to the National Bank. The 2026 reform integrates the EU Directive's pay transparency metrics directly into this existing filing.

What role does the Works Council play in Belgian pay transparency?

The Ondernemingsraad / Conseil d'entreprise (worker's council) must discuss the gender pay gap report within three months of the financial year-end. Where pay disparities are not corrected, an internal mediator (Bemiddelaar / Médiateur) must be appointed.

What is the Be-Magic project?

Be-Magic is a Belgian government project providing methodology for gender-neutral job classification, reducing the equal value mapping burden under the EU Directive.

How does Belgium's 50-employee threshold compare to the EU Directive?

The EU Directive's reporting threshold is 100 employees. Belgium has required biennial pay gap reporting for employers with 50+ employees since 2012 and is expected to retain this lower threshold under transposition.
