Pay transparency and expatriate compensation: what changed in June 2026
On 7 June 2026 the EU Pay Transparency Directive reached its transposition deadline: all 27 member states were required to have written it into national law. The directive never mentions expatriates. It still lands harder on mobility desks than on almost any other function, because it makes unexplainable compensation a litigation surface, and no population is harder to explain than assignees. This page sets out what the directive requires, on what dates, and what a mobility and finance team should have ready before the first reporting wave in June 2027.
What the directive requires
Directive (EU) 2023/970 was adopted on 24 April 2023, with a transposition deadline of 7 June 2026, now behind us; obligations apply per each country's transposition state, so the accurate phrasing is that duties phase in from June 2026 rather than biting everywhere at once. The obligations, per the Council of the EU's explainer and the directive text:
Hiring transparency, all employers regardless of size: salary range or starting pay disclosed in the vacancy or before interview; asking candidates about pay history is prohibited.
Worker information rights: any worker can request average pay levels, broken down by sex, for categories of workers doing equal work or work of equal value, plus the objective, gender-neutral criteria used for pay and progression.
Gender pay gap reporting for employers with 100+ workers: organizations with 250+ employees report annually from 7 June 2027; 150-249 report by 7 June 2027 and then every three years; 100-149 report by 7 June 2031 and then every three years, per Ogletree Deakins' wave-by-wave tracker.
Joint pay assessment: a reported gap above 5% in any category of workers, not justified by objective, gender-neutral criteria, triggers a mandatory joint pay assessment with worker representatives.
Reversed burden of proof and sanctions: in pay discrimination claims the employer must prove there was no violation; remedies include full back pay, and penalties must include fines.
Why this is a mobility problem
Three facts stack. First, assignees who remain employed by an in-scope EU entity are inside the reporting population; posting someone to Singapore does not remove them from the employer's category-level pay data. Second, the directive's concept of pay explicitly covers complementary or variable components, including benefits in kind: cost-of-living allowances, housing, schooling, mobility premiums and tax gross-ups are inside the comparison, not outside it. Third, expatriate compensation is structurally the least explainable pay in the company: it is assembled from balance-sheet layers calculated in different vendor systems, in different currencies, often documented only in the vendor's own files. Put together: the highest-paid, worst-documented population in the company now sits inside a statutory comparison whose 5% threshold triggers a joint pay assessment, under a reversed burden of proof.
The mid-market twist is the 100-249 band. These employers never had a statutory pay-reporting duty before; many run exactly the 50-500 assignee mobility programs that operate on spreadsheets. They face a new legal instrument with the weakest data infrastructure, and their first report (June 2027 for the 150-249 band) is now under a year away.
The same direction of travel: A1 digitalization
Pay transparency is not an isolated instrument. Intra-EU postings require A1 certificates proving social security affiliation: 5.5 million postings were reported in 2023, with administrative costs estimated at EUR 477-635 million per year excluding road transport, per the European Parliament's ESSPASS study754194_EN.pdf). The European Commission is digitalizing this layer through the European Social Security Pass: two consortia piloted digital issuing and real-time verification of A1 certificates through 2025, with an EU-wide deployment decision to follow. Real-time verifiable A1s mean labour inspectorates can check assignment data on the spot. Across pay transparency, posted-worker enforcement and social security digitalization, every new instrument assumes the same thing: that the employer can produce clean, structured, per-assignee, per-country data on demand. Fragmented vendor stacks cannot. PDFs and spreadsheets cannot.
What to have ready before June 2027
Treat the first reporting wave as a data deadline, not a legal one; counsel drafts the report, but the data has to exist first. Four preparations pay off regardless of which member state's transposition applies. Category-level pay data that includes assignees: base, allowances, benefits in kind and gross-ups decomposed per component, per person, per period. Explainable criteria: the policy logic (tier, corridor, family size) that generates each component, documented and versioned. An audit trail: for any figure, the source system, calculation method and date it was computed. A dry run: compute your gap by category now, find the unexplainable 5%+ gaps while they are an analytics finding rather than a joint pay assessment.
One boundary worth stating plainly: this is a data problem and a legal problem, and they have different owners. Ask & Chart makes the numbers defensible: per-component decomposition of assignee compensation, deterministic category analytics, provenance on every figure. Your counsel makes the legal argument. What we remove is the scenario where the argument fails because the data behind it cannot be reproduced.
Frequently asked questions
Do expat allowances count in gender pay gap reporting?
Yes. The directive's pay concept covers complementary and variable components, including benefits in kind, so assignment allowances, premiums and gross-ups sit inside the comparison and must be explainable.
When is the first report due?
Employers with 250+ workers report annually from 7 June 2027; the 150-249 band reports by 7 June 2027 and then every three years; the 100-149 band starts by 7 June 2031. Hiring transparency and information rights apply per national transposition from June 2026.
What triggers a joint pay assessment?
A gender pay gap above 5% in any category of workers that the employer cannot justify on objective, gender-neutral criteria. The assessment is conducted jointly with worker representatives.
