Belgium Pay Equity Overview

Overview

Belgium has long been recognized as a frontrunner in the European Union regarding gender pay equity, demonstrating a sustained commitment to the principle of equal pay for equal work or work of equal value. This commitment is deeply embedded in its legal and social dialogue framework, with the first significant national collective bargaining agreement on equal pay dating back to 1975. The country's approach reflects a blend of legislative mandates and the active involvement of social partners, aiming to systematically address and reduce the gender pay gap. Belgium's dedication to this principle is evident in its relatively low gender pay gap figures compared to the EU average, although disparities persist in certain areas and require continuous monitoring and intervention.

According to harmonized European statistics, the gender pay gap in Belgium stood at 0.7% in 2023, indicating that women earned, on average, 0.7% less per hour worked than their male counterparts. This figure represents a significant decrease of 6.8 percentage points over the past decade, positioning Belgium as one of the best-performing countries in the EU, surpassed only by Luxembourg. The European Union average, for comparison, was 12.0% in the same year. However, it is important to note that different methodologies can yield varying results; for instance, the unadjusted gender pay gap, which does not account for factors like education or job type, was reported at 5% in 2022 by Statbel and 5.8% in 2019 by other sources, while annual gross salaries showed a gap of 20% in 2022, according to the Belgian Institute for the Equality of Women and Men. These varying statistics highlight the complexity of measuring pay gaps and the need for comprehensive data collection and analysis to understand the full scope of the issue.

The evolution of pay equity in Belgium has been a continuous process, building upon foundational legal instruments and adapting to new challenges and international standards. From the early adoption of Collective Bargaining Agreement (CBA) No. 25 in 1975, which enshrined the principle of equal pay, to the comprehensive Gender Pay Gap Law of 2012, Belgium has progressively strengthened its legislative arsenal. The ongoing transposition of the EU Pay Transparency Directive (2023/970) further underscores this trajectory, introducing enhanced transparency measures and enforcement mechanisms. These developments aim not only to close the remaining pay gaps but also to foster a culture of transparency and accountability across all sectors of the Belgian economy, ensuring that remuneration is based on objective, gender-neutral criteria and that any unjustified disparities are systematically addressed.

Regulatory Approach

Belgium's regulatory approach to pay equity is characterized by a mandatory framework that combines proactive reporting obligations with robust enforcement mechanisms. The cornerstone of this approach is the Act on reducing the gender pay gap of 22 April 2012, which introduced specific requirements for companies to analyze and report on their wage structures. This law mandates that differences in pay and labor costs between men and women be outlined in the company's annual audit, known as the 'social balance,' which is then transmitted to the National Bank for public availability. This ensures a degree of public scrutiny and accountability regarding gender-based remuneration disparities, providing a foundational layer of transparency.

Beyond the annual social balance, the 2012 Act stipulates that companies employing more than 50 employees must conduct a comparative analysis of the wage structure of their female and male employees every two years. If this analysis reveals that women earn less than men, the company is then required to develop and implement an action plan to address and rectify the identified pay gaps. For larger employers, specifically those with 100 or more employees, a more comprehensive report is required, delving into data such as worker category, seniority, function, and qualifications, all disaggregated by gender. This tiered approach ensures that reporting requirements are proportionate to company size while still promoting a thorough examination of pay practices across the corporate landscape and encouraging proactive remediation.

The regulatory philosophy in Belgium emphasizes both prevention and remediation. The legal framework encourages the use of gender-neutral job classification and evaluation systems, with the Ministry of Employment actively checking these systems at the industry level. The upcoming transposition of the EU Pay Transparency Directive (2023/970) will further enhance this approach by introducing new obligations, such as mandatory disclosure of pay ranges in job advertisements, a ban on salary history inquiries, and increased employee rights to information. Belgium's draft legislation for transposing this directive, published on March 15, 2025, aims for a "gold-plated" implementation, setting stricter thresholds (a 3% unexplained pay gap triggering corrective action, compared to the EU's 5%) and empowering social partners, thereby reinforcing the country's commitment to leading on pay equity and ensuring a more robust and effective framework.

Key Pay Equity Legislation

• Belgian Employee Pay Protection (Act, In Force (Amended), 1965): The Act of 12 April 1965 on the protection of remuneration generally regulates the payment of wages, ensuring that employees receive their due compensation. In the context of pay equity, this Act confirms the principle that, in application of EU Treaty provisions, any employee can submit a claim to the competent court to enforce the principle of equal pay for male and female employees. It provides a legal avenue for workers to seek redress if their right to equal pay is violated, establishing a fundamental right to proper and non-discriminatory remuneration.
• Belgium Equal Pay CBA No. 25 (Regulation, In Force (Amended), 1975): This Collective Bargaining Agreement, rendered obligatory by Royal Decree, is a foundational piece of Belgian pay equity legislation. It explicitly imposes the principle of equal pay for men and women for equal work or work of equal value, directly translating Article 157 of the Treaty on the Functioning of the European Union into Belgian law. CBA No. 25 mandates that all gender-based distinctions in remuneration elements and conditions, including job evaluation systems, must be abolished. It requires sectors and companies to review their job evaluation and wage classification systems for gender neutrality and make necessary adjustments, with the text of CBA No. 25 required to be included in a company's work rules.
• Belgian Employment Contracts Act (Act, In Force (Amended), 1978): While not exclusively a pay equity law, the Employment Contracts Act of 3 July 1978 establishes the fundamental legal framework for employment relationships in Belgium. It governs various aspects of employment, including remuneration, and provides the general legal context within which equal pay principles are applied. The Act ensures that the terms and conditions of employment, including pay, are subject to legal oversight and can be challenged if discriminatory, thereby providing a broad legal basis for fair treatment in employment.
• Belgian Gender Equality Law (Act, In Force (Amended), 2007): This law, often referred to as the Law of 10 May 2007 to combat discrimination between women and men, is a comprehensive anti-discrimination statute that extends beyond pay to cover various aspects of employment and social life. It reinforces the principle of equal treatment and prohibits direct and indirect discrimination based on sex, including in remuneration. It provides a legal basis for individuals to challenge discriminatory practices and seek remedies, aligning Belgian law with broader European anti-discrimination frameworks.
• Belgian Anti-Discrimination Law (Act, In Force (Amended), 2007): The Belgian Anti-Discrimination Law of 10 May 2007 (alongside the Gender Equality Law) broadly prohibits discrimination on multiple protected grounds, including sex, in employment. It serves as a general legal safeguard against discriminatory practices, ensuring that pay decisions are not influenced by prohibited criteria. This law provides a framework for addressing discrimination in remuneration that might not be explicitly covered by gender-specific pay equity legislation, offering a wider scope of protection.
• Belgian Social Penal Code (Act, In Force (Amended), 2010): The Belgian Social Penal Code outlines the penalties for various infringements of social legislation, including those related to equal pay and non-discrimination. It provides the legal basis for imposing criminal or administrative fines on employers who fail to comply with their obligations under pay equity laws, such as reporting requirements or the implementation of action plans. This code ensures that there are tangible consequences for non-compliance, thereby strengthening the enforcement of pay equity regulations and deterring violations.
• Belgian Gender Pay Gap Law (Act, In Force (Amended), 2012): This Act, adopted on 22 April 2012, is a pivotal piece of legislation specifically designed to reduce the gender pay gap. It mandates that companies include differences in pay and labor costs between men and women in their annual social audit. Crucially, it requires companies with over 50 employees to conduct a biennial comparative analysis of wage structures and, if disparities are found, to produce an action plan to establish a gender-neutral remuneration structure. The law also encourages the appointment of internal mediators to address suspected discrimination, providing a structured approach to identifying and rectifying pay gaps.
• Pay Transparency French Community (Decree, In Force, 2024): The French Community of Belgium (Fédération Wallonie-Bruxelles) was the first jurisdiction in Belgium to transpose elements of the EU Pay Transparency Directive, with its decree entering into force on January 1, 2025. This regional decree applies to public sector employers within its jurisdiction and introduces requirements such as disclosing initial pay ranges in job advertisements, prohibiting salary history inquiries, and granting employees the right to request information on their pay and average pay for comparable work. It also mandates annual government reporting for certain entities, setting a precedent for the federal transposition.
• French Community Pay Transparency Decree (Decree, In Force, 2025): This decree, effective January 1, 2025, specifically applies to public sector employers within the French Community of Belgium. It is a direct result of the early transposition of the EU Pay Transparency Directive at a regional level. The decree formalizes the obligations for these employers regarding pay transparency, including the proactive disclosure of pay information and the prohibition of certain discriminatory practices during the hiring process. It signifies a regional commitment to enhanced pay equity before the federal implementation.

Covered Employers

The scope of pay equity regulations in Belgium primarily targets employers based on their size, with specific thresholds triggering different levels of reporting and compliance obligations. The foundational principle of equal pay for equal work or work of equal value, as enshrined in Collective Bargaining Agreement No. 25, applies to all employers and workers covered by the Act of 5 December 1968 on collective bargaining agreements and joint committees, essentially encompassing most employers in Belgium. This broad application ensures that the core principle of non-discrimination in pay is universally upheld, regardless of the employer's size or sector, forming the bedrock of the country's pay equity framework.

More specific and extensive obligations, particularly concerning pay gap reporting and analysis, are introduced by the Belgian Gender Pay Gap Law of 2012. This law mandates that companies with 50 or more employees must conduct a biennial comparative analysis of their wage structures, disaggregated by gender. These employers are required to outline differences in pay and labor costs between men and women in their annual social audit, which is then made publicly available via the National Bank. For companies with 50 to 99 employees, a simplified short-form report covering remuneration and benefits in full-time equivalents is sufficient, ensuring proportionality in reporting burdens.

Employers with 100 or more employees face more comprehensive reporting requirements. They must complete a detailed report that includes granular data on worker categories, seniority, qualifications, and functions, all broken down by gender. If these analyses reveal unexplained gender pay gaps, these larger employers are obliged to develop and implement an action plan to establish a gender-neutral remuneration structure. Furthermore, the recent regional transposition of the EU Pay Transparency Directive by the French Community of Belgium, effective January 1, 2025, applies to public sector employers within its jurisdiction, including organizations created by the Federation, educational institutions, and government administrations. The upcoming federal transposition of the EU Directive by June 7, 2026, will introduce new reporting thresholds: annual reporting for companies with 250+ employees starting June 2027, triennial reporting for 150-249 employees from June 2027, and triennial reporting for 100-149 employees from June 2031, progressively expanding the scope of detailed pay gap reporting across the private sector.

Employee Rights

Employees in Belgium are endowed with several key rights designed to ensure pay equity and transparency, which are continually being strengthened by national legislation and the ongoing transposition of European directives. Fundamentally, every employee has the right to equal pay for equal work or work of equal value, a principle firmly established by Collective Bargaining Agreement No. 25 and reinforced by the Gender Equality Law of 2007 and the Employee Pay Protection Act of 1965. This means that any gender-based distinctions in remuneration are prohibited, and employees can challenge such disparities through legal avenues, ensuring a robust legal foundation for individual claims.

Under the existing Gender Pay Gap Law of 2012, if an employee suspects pay discrimination, they have the right to turn to their company's internal mediator for assistance. This mechanism provides an initial avenue for resolving disputes and addressing concerns within the workplace, fostering a culture of internal resolution. Furthermore, the law encourages transparency by requiring employers to conduct and report on gender pay gap analyses, which, while primarily for internal discussion with employee representatives, contribute to a more informed environment where employees can raise questions about pay fairness and advocate for equitable remuneration practices.

The upcoming full transposition of the EU Pay Transparency Directive by June 7, 2026, will significantly expand employee rights. Employees will gain the right to request written information about their individual pay level, as well as the average pay level, broken down by gender, for employees performing the same work or work of equal value. Employers will be required to respond to such requests within a maximum of two months. Crucially, pay secrecy clauses that prevent employees from discussing their remuneration will be prohibited, fostering a more open dialogue about wages. Additionally, employers will no longer be permitted to ask job candidates about their current or previous salary history, and initial pay or pay ranges must be disclosed in job advertisements, empowering candidates with more information during the recruitment process and promoting greater transparency from the outset of employment.

Governance & Enforcement Bodies

The enforcement and governance of pay equity regulations in Belgium involve a multi-layered institutional framework, encompassing federal government bodies, social partners, and specialized institutes. At the federal level, the Federal Public Service Employment, Labour and Social Dialogue (FPS Employment) plays a central role in developing labor policy and overseeing the implementation of employment laws, including those related to pay equity. Its various directorates, such as the Directorate General Control on Labour Legislation, are responsible for carrying out inspections and verifying compliance with labor conditions, including remuneration, ensuring adherence to legal standards across the country.

Another critical institution is the Institute for the Equality of Women and Men (IEWM), established by the Law of 16 December 2002. The IEWM is a public institution responsible for promoting gender equality and combating discrimination based on sex. It plays a significant role in monitoring the gender pay gap, publishing annual reports, and providing expertise and recommendations for policy development. Under the Gender Pay Gap Law of 2012, the IEWM receives reports from companies and contributes to the assessment of gender neutrality in job classification systems. Works Councils and trade union delegations also serve as crucial internal enforcement bodies, receiving and discussing company pay gap reports and having the authority to decide on action plans, thereby integrating social partners into the compliance process.

The National Bank of Belgium is involved in the process by receiving and making publicly available the annual 'social balance' audits from companies, which include data on pay and labor cost differences between men and women, providing a centralized data repository for public scrutiny. The Social Inspectorate, operating under the FPS Employment, is responsible for enforcing compliance through workplace audits and investigations, ensuring that employers meet their legal obligations. Furthermore, the Belgian legal system, including labor courts, provides avenues for employees to seek redress for pay discrimination. The upcoming EU Pay Transparency Directive will also necessitate the designation of a supervisory body to publish gender pay gap information, further enhancing external oversight and coordination among these various entities to ensure comprehensive and effective enforcement.

Monitoring & Compliance

Monitoring and compliance with pay equity regulations in Belgium are structured through a combination of regular reporting, internal analysis, and external oversight. A key mechanism is the annual 'social balance' audit, which all organizations are required to submit to the National Bank of Belgium. This audit must include disaggregated data on the differences in total pay and labor costs paid to men and women, making this information publicly available and providing a baseline for monitoring gender pay disparities at a macro level, allowing for broad statistical analysis and trend identification.

More detailed compliance is ensured through the biennial comparative analysis of wage structures, mandated by the Gender Pay Gap Law of 2012 for companies with 50 or more employees. Employers with 50 to 99 employees complete a short-form report, while those with 100 or more employees must submit a comprehensive report detailing remuneration by worker category, seniority, qualifications, and function, all broken down by gender. These reports are provided to the Works Council or, in its absence, the trade union delegation or employment committee, at least 15 days before a meeting for their consideration. The discussion of these reports within three months of the financial year-end is crucial, as the employee representatives can then decide whether an action plan is necessary to establish a gender-neutral remuneration structure, thereby empowering internal stakeholders in the compliance process.

Beyond these reporting obligations, the Belgian framework also emphasizes the gender neutrality of job classification and evaluation systems. Collective Bargaining Agreement No. 25, as amended, makes it compulsory for joint committees to analyze their job classifications for gender neutrality, a process checked by the Employment Ministry. The forthcoming EU Pay Transparency Directive will introduce further monitoring requirements, including mandatory joint pay assessments if a gender pay gap of 5% or more (or 3% in Belgium's proposed implementation) is identified and cannot be justified by objective, gender-neutral criteria. These assessments will involve a root cause analysis and proposed corrective measures developed in consultation with employee representatives, with progress reports submitted to Works Councils and the Institute for the Equality of Women and Men, ensuring a thorough and collaborative approach to addressing identified pay gaps.

Penalties & Enforcement

Belgium's pay equity framework includes a range of penalties and enforcement mechanisms designed to ensure compliance and provide redress for victims of discrimination. Non-compliance with the reporting obligations under the Gender Pay Gap Law of 2012, such as the failure to publish broken-down data in the social balance or to submit the biennial analysis report, can trigger level-two sanctions under the Belgian Social Penal Code. These sanctions include criminal fines ranging from €400 to €4,000 or administrative fines ranging from €200 to €2,000. These penalties serve as a deterrent and underscore the mandatory nature of the reporting requirements, ensuring that employers take their obligations seriously.

In cases of non-compliance with Collective Bargaining Agreement No. 25, which mandates equal pay for equal work, the sanctions are primarily civil. An employee who has experienced pay discrimination can file a complaint and may be entitled to reinstatement in their position. If the employer refuses reinstatement, the employee can claim a lump-sum indemnity before the labor courts, typically equal to six months' remuneration, in addition to any statutory termination indemnities. This civil remedy aims to compensate the employee for the discrimination suffered and to encourage employers to rectify discriminatory practices, providing a direct avenue for individual redress.

The upcoming transposition of the EU Pay Transparency Directive will introduce even stronger enforcement mechanisms and potentially more substantial penalties. Member States are required to put in place effective, proportionate, and dissuasive penalties for non-compliance, including fines. Belgium's draft legislation proposes fines up to €25,000 per violation for non-compliance, with repeat offenders facing publication of their violations on a government "name and shame" register. Furthermore, if a presumption of discrimination is established by a court or if an employer fails to comply with pay transparency obligations, the burden of proof will shift to the employer, making it easier for employees to pursue claims. Employees who have experienced pay discrimination will be entitled to full compensation, including uncapped backpay. The appeals process for such claims typically involves the labor courts, with further appeals possible to higher judicial instances, ensuring a comprehensive and robust system for challenging and remedying pay discrimination.

International Alignment

Belgium's pay equity legislation is strongly aligned with international and European standards, reflecting its commitment to global and regional efforts to promote gender equality in the workplace. The principle of equal pay for equal work or work of equal value, which forms the bedrock of Belgian law, is directly derived from Article 157 of the Treaty on the Functioning of the European Union (TFEU). This foundational EU principle has been translated into Belgian law through instruments such as Collective Bargaining Agreement No. 25, which has been obligatory since 1975, demonstrating a long-standing commitment to European legal principles.

The country's legislative framework also reflects the influence of international labor standards, particularly those set by the International Labour Organization (ILO). While specific mentions of ILO Conventions C100 (Equal Remuneration Convention) and C111 (Discrimination (Employment and Occupation) Convention) are not always explicit in national legislation, the principles they embody are deeply integrated into Belgium's anti-discrimination and equal pay laws. Belgium's consistent efforts to reduce its gender pay gap, which is among the lowest in the EU, demonstrate its practical alignment with these international commitments. In 2023, the harmonized gender pay gap in Belgium was 0.7%, significantly lower than the EU average of 12.0%, showcasing its strong performance relative to its European peers and its dedication to achieving substantive equality.

Currently, Belgium is in the process of transposing the EU Pay Transparency Directive (2023/970) into national law, with a deadline of June 7, 2026. This directive aims to strengthen the application of the equal pay principle through enhanced transparency and enforcement mechanisms. Belgium has demonstrated a proactive approach, with the French Community already implementing parts of the directive in January 2025, and federal draft legislation published in March 2025. The proposed Belgian implementation is notably ambitious, aiming for a "gold-plated" approach with stricter thresholds for triggering corrective actions (a 3% unexplained pay gap compared to the EU's 5%). This proactive and stringent transposition further solidifies Belgium's position as a leader in pay equity within the European context, setting a high standard for other Member States.

Future Developments

The landscape of pay equity regulations in Belgium is poised for significant developments, primarily driven by the ongoing transposition of the EU Pay Transparency Directive (2023/970). Member States are mandated to transpose this directive into national law by June 7, 2026. Belgium has already taken proactive steps, with the French Community having partially transposed the directive with effect from January 1, 2025, for public sector employers within its jurisdiction. Federally, a draft law integrating the EU directive into Belgium's existing Gender Pay Gap Law of 2012 was published on March 15, 2025, with parliamentary committee debates expected to conclude by June 30, 2025, and final approval by the Federal Parliament anticipated in December 2025, indicating a clear legislative pathway.

These upcoming reforms will introduce several new obligations and enhance existing ones. Key changes include mandatory disclosure of initial pay or pay ranges in all job advertisements, a prohibition on asking candidates about their salary history, and the banning of pay secrecy clauses in employment contracts. Employees will gain a new right to request written information about their individual pay level and the average pay levels, broken down by gender, for comparable work. Furthermore, new gender pay gap reporting obligations will be phased in: companies with 250 or more employees will report annually starting June 2027, those with 150 to 249 employees every three years from June 2027, and companies with 100 to 149 employees every three years from June 2031, ensuring a gradual but comprehensive expansion of reporting requirements.

Notably, Belgium's proposed implementation of the EU Directive is more ambitious than the minimum requirements, often referred to as a "gold-plated" approach. For instance, the Belgian proposal sets a stricter threshold of a 3% unexplained pay gap (compared to the EU's 5%) to trigger mandatory joint pay assessments and corrective action plans. These assessments will involve a root cause analysis and proposed corrective measures in consultation with employee representatives. The political outlook indicates a strong commitment to these reforms, with Belgium having pledged to promptly implement the directive and prioritize reducing gender gaps during its EU Presidency in the first half of 2024. These developments signify a continuous strengthening of Belgium's pay equity framework, aiming for greater transparency and more effective remediation of pay disparities across all sectors.
