Employers should count workers for EU Pay Transparency Directive reporting by first identifying the correct reporting employer and then applying the headcount method required by the relevant Member State's implementation of Article 9. The Directive itself sets the reporting bands at fewer than 100, 100 to 149, 150 to 249 and 250 workers or more, but Article 9 does not provide a complete EU-wide formula for every headcount scenario. Recital 34 notes that the worker-number criterion was set taking account of Commission Recommendation 2003/361/EC, but employers should not automatically import the Recommendation's SME headcount methodology unless national law or authoritative guidance makes it applicable. The chosen method should be documented and reproducible.

Start With the Reporting Employer, Not the Group's Global Headcount
Before counting workers, an organisation needs to identify which employer is subject to the reporting obligation. A corporate group may contain multiple legal employers, subsidiaries and establishments across several Member States. Adding every person in a global group together can produce a number that does not answer the legal question, while counting only one payroll population can also be wrong if national implementation defines the reporting employer differently. The scope file should therefore begin with the relevant legal entity or employer, the Member State whose rules apply and the legal basis for treating that population as the reporting population. Only then should the employer apply the relevant worker-count method.
Article 9 Sets the Bands but Not a Complete Headcount Formula
Article 9 is precise about the reporting bands. Employers with 250 workers or more report annually from 2027, employers with 150 to 249 workers report every three years from 2027, and employers with 100 to 149 workers report every three years from 2031. Employers below 100 are outside the Directive-level mandatory recurring reporting timetable, although Member States may require smaller employers to report. What Article 9 does not do is provide a detailed calculation rule covering every question such as measurement dates, fluctuations during the year, group restructurings or the treatment of every non-standard working arrangement. Those operational issues should be checked against national implementation and authoritative guidance.
Recital 34 Refers to the EU SME Recommendation, but Use It Carefully
Recital 34 says that the number-of-workers criterion used for pay reporting was set taking into account Commission Recommendation 2003/361/EC on micro, small and medium-sized enterprises. That reference helps explain the policy context for using employer headcount as a threshold. It should not be read as an automatic instruction that every employer must apply the Recommendation's annual-work-unit methodology to Article 9 reporting. The Recommendation has its own purpose and detailed SME rules. Unless national implementing legislation or authoritative pay-transparency guidance adopts that methodology, employers should not silently substitute it for the counting rule required in their jurisdiction.
Part-Time and Fixed-Term Status Should Not Be Treated as Automatic Exclusions
The Directive's scope recitals specifically discuss part-time and fixed-term workers where they have the required employment contract or employment relationship. That means an employer should not remove these workers from a threshold calculation merely because they work fewer hours or have a fixed end date. The separate question is how the applicable national reporting rule counts them for headcount purposes. A jurisdiction might use persons, full-time equivalents, a reference date, an average or another method. The employer should follow the applicable rule and document it. Working pattern and legal worker status should therefore be analysed before any numerical adjustment is made.
Agency Workers and Other Non-Standard Relationships Need a Legal Basis
Temporary agency arrangements are a good example of why headcount cannot be reduced to whoever is physically present at a workplace. The Directive's recitals refer to persons who have an employment contract or employment relationship with a temporary agency. The user undertaking and the agency can therefore have different legal relationships with the same individual. Employers should check which entity is the relevant employer for the obligation being assessed and how national implementation treats that relationship for reporting thresholds. The same caution applies to other non-standard arrangements. Inclusion or exclusion should be supported by the applicable legal rule rather than by an internal label such as contractor, contingent worker or external staff.
Choose and Document the Correct Reference Date or Period
Headcount can move above and below a threshold during a year. An employer may hire rapidly, reduce headcount, acquire another business or transfer workers between entities. The Directive's reporting bands alone do not resolve which point in time or averaging period should be used for every national reporting system. Employers should therefore identify the reference rule in the applicable national implementation or official guidance and preserve evidence of the calculation. The record should show the period used, the workforce source data, material joins and leavers, reorganisations and the date on which the threshold conclusion was approved. This makes the decision reproducible if the reporting band is later questioned.
Do Not Reuse a Tax, Accounting or Works-Council Headcount Without Checking
Many organisations already maintain several different employee counts. Finance may use one definition for accounting, HR another for workforce planning, tax teams another for statutory filings and labour-relations teams another for representation thresholds. None of those numbers should automatically become the Article 9 headcount simply because it is convenient. The definitions, reference periods and treatment of part-time or temporary workers may differ. A good control is to name the source count being proposed, compare its methodology with the national pay-transparency rule and document any adjustments. This prevents an employer from applying a familiar but legally unrelated threshold calculation to the Directive.
Maintain a Threshold File That Can Be Reproduced
The final worker-count decision should be treated as compliance evidence. The file should identify the reporting employer, jurisdiction, legal source, reference date or period, source-system extract, worker categories included, exclusions and their legal basis, treatment of organisational changes and the resulting band. It should also record who reviewed and approved the conclusion. Employers close to 100, 150 or 250 workers should refresh the file when headcount changes materially rather than waiting for the reporting deadline. A reproducible threshold file helps HR, legal, payroll and compensation teams work from the same population and reduces the risk that reporting frequency is selected from an undocumented estimate.
Frequently Asked Questions
Does the Directive itself provide a full formula for counting workers?
Article 9 establishes the reporting bands but does not set out a complete operational formula for every workforce-count scenario. Employers should confirm the method required under applicable national implementation and guidance.
Should employers automatically use the EU SME annual-work-unit method?
No. Recital 34 says the worker-number criterion was set taking account of Commission Recommendation 2003/361/EC, but that does not by itself make the Recommendation's detailed SME headcount method the Article 9 counting rule in every Member State.
Should part-time workers automatically be excluded from the count?
No. Part-time status is not an automatic exclusion from the Directive. The employer should apply the worker definition and counting method required by the applicable national implementation.
