Pay Equality Register Spain (Registro Retributivo de Igualdad)

A Pay Equality Register Spain (Registro Retributivo de Igualdad) is a mandatory annual accounting instrument that all Spanish employers — regardless of workforce size — must maintain under Real Decreto 902/2020, de 13 de octubre, de igualdad retributiva entre mujeres y hombres, Article 5, developed from the mandate of Ley Orgánica 3/2007, de 22 de marzo, para la igualdad efectiva de mujeres y hombres (LOI), Article 28. The register records and breaks down average remuneration — salario medio — for all employees by sex, job group (grupo profesional), job category (categoría profesional), and pay level (nivel retributivo), covering every component of remuneration: base salary (salario base), supplementary pay (complementos salariales), overtime pay (horas extraordinarias), extra payments (percepciones extrasalariales including meal vouchers, transport allowances, housing subsidies), and non-wage benefits in kind (retribución en especie).

RD 902/2020 was adopted to implement the principle of equal pay for equal work or work of equal value — «a trabajo igual, salario igual; a trabajo de igual valor, salario igual» — established in Estatuto de los Trabajadores (ET) Article 28.1 as amended by Real Decreto-ley 6/2019, de 1 de marzo, de medidas urgentes para garantía de la igualdad de trato y de oportunidades entre mujeres y hombres en el empleo. The pay equality register serves as the evidentiary foundation for detecting gender pay gaps — defined in RD 902/2020 Article 3 as the average difference in gross hourly earnings between female and male employees — and for demonstrating that any pay differences are justified by objective, non-discriminatory, non-gender-based criteria.

The register's mandatory scope covers all remuneration elements, including direct remuneration components and variable payments. RD 902/2020 Article 5.2 specifies that the register must be broken down by sex within the following classification: job groups (grupos profesionales) established in the applicable collective agreement (convenio colectivo sectorial or company-level agreement); equal work (trabajo igual) as defined by identical job content; and work of equal value (trabajo de igual valor) — work that requires the same or equivalent levels of training, effort, responsibility, and working conditions.

The pay equality register is distinct from, but related to, the pay audit (auditoría retributiva) required for companies with 50 or more employees under RD 902/2020 Article 7. Companies above the 50-employee threshold must also prepare a pay equality plan (plan de igualdad) under LOI Article 46 — the pay audit forms part of that plan. Companies below 50 employees are not required to prepare a formal pay equality plan or audit but must maintain the register and make it available for inspection.

The Inspección de Trabajo y Seguridad Social (ITSS) has authority to inspect the pay equality register during routine workplace inspections and in response to complaints of wage discrimination under ET Article 28.1. The Ministerio de Igualdad and the Instituto de la Mujer y para la Igualdad de Oportunidades publish annual data from pay equality inspections. Employers found to have discriminatory pay structures without objective justification face infringement proceedings under Ley sobre Infracciones y Sanciones en el Orden Social (LISOS) Articles 7.13 and 8.12.

The Tribunal Supremo (Social Chamber) has addressed pay equality in multiple rulings — STS 914/2021, STS 677/2022 — requiring that comparators for equal value assessment be genuinely comparable positions within the same organisational context, and that the burden of proof shifts to the employer to justify pay differences once a prima facie case of discrimination is established by the employee. The Tribunal Constitucional has recognised pay discrimination as a violation of Article 14 CE (equality principle) and Article 35 CE (right to work and equal remuneration).

A Pay Equality Register Spain is needed by every Spanish employer — from sole traders with one employee to large multinational companies — given that RD 902/2020 Article 5.1 establishes the obligation universally, without any workforce size threshold. The register must be prepared at least annually and updated whenever relevant changes to the workforce or pay structures occur.

The register is needed when preparing for an Inspección de Trabajo y Seguridad Social (ITSS) inspection, as the pay equality register is one of the first documents requested by labour inspectors during workplace audits focused on gender equality compliance. Failure to produce the register is itself an infringement under LISOS Article 7.13, independent of whether actual wage discrimination exists.

The document is required as a prerequisite for companies with 50 or more employees that must negotiate a pay equality plan (plan de igualdad) under LOI Article 46. The workers' representatives (comisión negociadora del plan de igualdad) have the right to access the pay equality register data, and the register forms the factual basis for the pay audit (auditoría retributiva) within the equality plan.

A pay equality register is needed when an employee files a wage discrimination complaint before the Juzgado de lo Social or the ITSS under ET Article 28.1, as the employer's best defence is a properly maintained register demonstrating objective, non-discriminatory grounds for any pay differences between female and male employees performing equal or equivalent work.

The register is needed when a company participates in public procurement tenders that require certification of pay equality compliance under Ley 9/2017 de Contratos del Sector Público, Article 202, which allows contracting authorities to require tenderers to maintain equality plans and registers as special execution conditions.

The document is also essential when applying for the Distintivo «Igualdad en la Empresa» awarded by the Ministerio de Igualdad under LOI Article 50 — demonstrating a properly maintained pay equality register with documented gap analysis and corrective action is a core requirement of the application process.

Parties in Spain should prepare a Pay Equality Register Spain (Registro Retributivo de Igualdad) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under the Estatuto de los Trabajadores (ET) RDL 2/2015, Spanish employment law governs contracts, dismissals, and working conditions. The Tesorería General de la Seguridad Social (TGSS) administers social security contributions. The Servicio Público de Empleo Estatal (SEPE) manages unemployment benefits. The Inspección de Trabajo y Seguridad Social enforces labour compliance. The Juzgados de lo Social hear employment disputes under the Ley Reguladora de la Jurisdicción Social (Ley 36/2011). Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.

A valid Pay Equality Register Spain under RD 902/2020 Article 5 must contain the following mandatory elements to satisfy Inspección de Trabajo y Seguridad Social (ITSS) inspection requirements and demonstrate compliance with the equal pay principle of ET Article 28.1.

Registration Period: The calendar year or 12-month period covered by the register, consistent with the company's financial year or the annual review cycle of any applicable pay equality plan. RD 902/2020 Article 5.3 requires annual preparation — a register that is not updated annually is automatically non-compliant.

Breakdown by Sex, Group, and Pay Level: The core data structure of the register — average gross annual remuneration broken down by: (1) sex (female / male); (2) job group (grupo profesional) per the applicable collective agreement; (3) job category or level (categoría/nivel); and (4) type of work: equal work (trabajo igual) and work of equal value (trabajo de igual valor). The breakdown must cover 100% of the workforce, including part-time employees, temporary workers, and fixed-term contract workers.

Remuneration Components: The register must separately record each pay component per RD 902/2020 Article 5.2: base salary (salario base); salary supplements (complementos salariales — seniority, language, shift, performance, destination, quality supplements); extraordinary payments (pagas extraordinarias); overtime and on-call payments; non-wage perceptions (percepciones extrasalariales — meal vouchers, transport, housing); and benefits in kind (retribución en especie — company car, health insurance, equity schemes). Aggregating all components without disaggregation makes it impossible to identify where the pay gap originates.

Gender Pay Gap Calculation: The total gender pay gap (brecha salarial total) expressed as a percentage, calculated as ((male average salary − female average salary) / male average salary) × 100, for each job group and for the company overall. RD 902/2020 Annex I provides the recommended calculation methodology. Any gap above 5% across equivalent groups triggers a presumption of potential discrimination requiring objective justification.

Objective Justification of Pay Differences: Where pay differences between female and male employees exist, the register must document the objective, non-discriminatory reasons for each difference: seniority, qualifications, individual performance metrics, market benchmarking, geographic location, or working time. Justifications that reference gender-correlated factors (part-time work prevalence among women, career interruptions for caregiving) are not accepted as objective justifications — they confirm structural discrimination requiring corrective action.

Employee Representative Access: Evidence that workers' representatives (comité de empresa, delegados de personal, or sección sindical) have been informed of the register per RD 902/2020 Article 5.4. Representatives have the right to access the register data at aggregate level — disaggregated individual salaries are not required to be disclosed.

Given that ITSS inspectors are specifically trained in pay equality analysis and that pay discrimination sanctions under LISOS can reach €7,500 per infringement (Article 40.1.b), maintaining a properly structured register from the outset is far less costly than remedying a discrimination finding.
