A total-rewards pay equity audit should examine more than base salary. Under Directive (EU) 2023/970, pay includes basic salary and other cash or in-kind consideration received from the employer in respect of employment, while Article 9 requires covered employers to report gender pay gap information for complementary or variable components. A practical audit therefore maps all material reward components, groups workers using a defensible same-work or work-of-equal-value methodology, normalises the data, compares salary and variable reward separately, investigates unexplained differences and documents the reasons for any adjustments or remediation. The Directive does not prescribe one universal audit model, so the methodology should be transparent, repeatable and aligned with national implementing law.

Start With a Complete Inventory of Total Rewards
The first step is to identify the full set of remuneration components that may affect the comparison. Article 3 of Directive (EU) 2023/970 uses a broad definition of pay that includes basic salary and other cash or in-kind consideration received from the employer in respect of employment. A total-rewards inventory can therefore include bonuses, commissions, overtime, shift premiums, allowances, benefits, pensions, company vehicles and other material reward. The goal is not to force every item into one calculation immediately. It is to prevent relevant components from being omitted simply because they sit outside the main payroll salary field or are administered by a different team.
Build the Comparison Group Before Interpreting Pay Differences
A pay difference is meaningful only when the workers being compared are in a defensible comparison group. Article 4 requires pay structures to support assessment of the same work or work of equal value using objective and gender-neutral criteria such as skills, effort, responsibility and working conditions. The audit should therefore establish worker categories before drawing conclusions from reward differences. Job architecture, job descriptions, evaluation factors and classification rules can help create those categories. This avoids comparing unrelated jobs merely because they share a title and also reduces the risk that existing pay levels influence the decision about whether jobs are genuinely comparable in value.
Clean and Normalise the Compensation Data
Total-reward data usually comes from several systems and often uses different time periods, currencies, units and payroll codes. The audit methodology should define the population, reporting period, currency treatment, annualisation rules, part-time treatment, benefit valuation method and handling of one-off payments. Duplicate employees, missing records and inconsistent job identifiers should be resolved before analysis begins. The objective is not to manipulate the figures until they look comparable. It is to create a documented dataset in which the same rule is applied consistently to comparable workers. Every transformation should be reproducible so another reviewer can understand how the final numbers were produced.
Analyse Base Pay and Variable Reward Separately
One headline total-compensation figure can hide the source of a gap. The audit should therefore examine basic salary and complementary or variable reward as separate layers before considering the combined total. This is consistent with Article 9, which requires covered employers to report gender pay gap information for complementary or variable components and to provide category-level pay gaps separated between basic salary and complementary or variable components. A worker category may show little difference in base pay but a substantial gap in bonuses, commission, overtime or benefits. Separating the layers helps identify which part of the reward system should be investigated.
Investigate the Drivers Behind Unexplained Differences
A statistical or numerical difference is a starting point, not a legal conclusion. The next step is to examine the factors that may explain it. Depending on the component, those factors can include role scope, experience, performance, quota, territory, overtime access, shift allocation, location, collective-agreement rules, benefit eligibility or another objective criterion. The employer should distinguish factors that are documented and consistently applied from explanations created only after the gap is discovered. Where discretion played a role, the audit should identify who made the decision, what information was used and whether comparable cases were treated consistently. Differences that remain unexplained should be escalated for further review.
Treat Remediation as a Controlled Decision
If an audit identifies a pay difference that cannot be justified by objective factors unrelated to sex, remediation should be deliberate and documented. Possible action may involve salary adjustment, bonus correction, benefit alignment, policy change, revised eligibility rules, job architecture changes or stronger controls over manager discretion. The correct response depends on the facts and applicable national law. The audit should record the issue, the rationale for the chosen action, the decision owner, the implementation date and any follow-up test. This creates an evidence trail and helps distinguish corrective action from arbitrary changes that could create new inconsistencies elsewhere in the reward structure.
Turn the Audit Into a Repeatable Governance Process
A useful pay-equity audit should be repeatable. Employers can assign owners for source data, job categories, valuation rules, analysis, legal review and remediation; maintain a version-controlled methodology; and define review triggers such as annual compensation cycles, acquisitions, major job-architecture changes or new national guidance. The same process can support Article 9 reporting, preparation for worker information requests and future joint pay assessments where relevant. The Directive does not require employers to use one specific audit template, so governance quality matters. A repeatable process reduces reliance on individual analysts and makes it easier to explain how conclusions were reached from one cycle to the next.
Frequently Asked Questions
Should a pay equity audit include benefits and variable pay?
Yes, where those items form part of employment-related remuneration. The Directive defines pay broadly and Article 9 separately requires reporting on complementary or variable components for covered employers.
Does the EU Pay Transparency Directive prescribe one audit methodology?
No. The Directive establishes legal requirements and reporting concepts, but employers still need a documented methodology for data preparation, comparison groups, valuation, analysis and investigation that also reflects national implementing law.
Is every pay gap found in an audit unlawful?
No. A difference can have legitimate objective explanations. The audit should identify, test and document those explanations and escalate differences that remain unexplained.
