Luxembourg’s Big Four headcount falls amid shift in delivery models

Luxembourg’s four largest audit and consulting firms appear to have shed about 800 domestic jobs in two years, a striking reversal for businesses that have long supplied the financial centre with a steady stream of graduates and internationally recruited specialists.

The combined workforce of PwC, Deloitte, EY and KPMG fell from 10,520 in January 2024 to 9,720 in January 2026, according to a Foundation IDEA calculation based on STATEC’s employer survey. That is a decline of about 7.6%, conventionally rounded to 8%.

Yet the headline does not amount to evidence of 800 layoffs, nor does it establish a broad collapse in audit, tax or advisory demand. Company reports covering 2025 show revenue growth, substantial recruitment and, in several cases, work being reorganised across borders. The more defensible conclusion is that a post-boom hiring correction is being combined with near-shoring, outsourcing and automation.

One large fall, three less certain stories

STATEC’s 2024 survey counted 3,860 people at PwC, 2,610 at Deloitte, 2,130 at EY and 1,920 at KPMG. One year later, the institute recorded 3,610 at PwC, 2,580 at Deloitte, 2,110 at EY and 1,960 at KPMG.

• PwC: the survey count fell by 250 in 2024 and then to 3,330 in January 2026, according to Le Quotidien’s report on the latest STATEC list. Its two-year reduction of 530 accounts for about two-thirds of the Big Four’s aggregate decline.
• Deloitte: STATEC recorded a modest fall of 30 between January 2024 and January 2025. Deloitte subsequently said it had approximately 2,600 professionals in November 2025, close to the earlier survey level.
• EY: the STATEC count slipped by 20 in the first year, but EY reported more than 2,300 employees in September 2025, above the January 2024 survey figure.
• KPMG: STATEC recorded a gain of 40 in the first year. KPMG later reported 1,762 staff at September 2025 under a definition excluding trainees, student contracts, subcontractors, certain assignees and people on long-term leave.

Those differences matter. STATEC’s list is drawn from a non-mandatory survey, rounds figures to the nearest ten and counts groups located in Luxembourg. The firms use different reporting dates and organisational boundaries. PwC’s own 3,665-person figure at June 2025, for example, includes 226 people in the Porto area rather than Luxembourg.

Michel-Edouard Ruben, the IDEA economist who highlighted the decline, supplied the appropriate warning: the figures should neither be ignored nor treated as a verdict on Luxembourg’s economic model.

Demand has slowed, not collapsed

The revenue numbers do not describe an industry in retreat. PwC Luxembourg reported 5% growth to €765.5 million for the year to June 2025. Deloitte reported a 5% increase to €535 million and said audit and assurance achieved double-digit growth. EY reported 10% growth to €457 million, including 11% in assurance, 9% in tax and 6% in consulting.

There is nevertheless evidence of a cooler market beneath those totals. EY consulting leader Laurent Moscetti said ESG transformation had slowed and large projects had been reduced or delayed. PwC’s advisory turnover rose only 1.7%, and managing partner François Mousel warned that the difficult conditions expected for 2025 would persist.

“We said in 2024 that 2025 would be a more challenging year and the sentiment remains the same for 2026.” — François Mousel, managing partner of PwC Luxembourg

Hiring has not stopped. Luxembourg Times reported that EY accepted 320 new starters in autumn 2025, unchanged from the previous year, while KPMG recruited 150. KPMG’s annual impact report recorded 387 hires across its financial year. These large intakes are consistent with normal Big Four turnover and with a correction from the unusually strong hiring of 2022 and 2023, rather than a closed door for graduates.

The location and content of work are changing

The clearest structural change is not simply fewer assignments, but a different delivery model. PwC calls its operation near Porto a core part of its future model. Its 226 employees there support Luxembourg clients across assurance, tax, accounting and advisory; 182 worked in assurance during the reporting year. PwC also says about 45% of its people live in Belgium, France or Germany, underlining how closely its workforce is tied to the cross-border labour market.

KPMG’s 2026 impact report likewise describes “additional job opportunities through strategic outsourcing”. The full report says repeatable work can be routed to delivery centres while Luxembourg professionals concentrate on judgement-heavy, client-facing and innovation-led tasks. Deloitte reported expanding automation, AI integration and new delivery models.

AI is therefore part of the restructuring, but the available evidence does not quantify jobs lost to it. The firms continued to recruit while investing in the technology. For now, near-shoring and redesigned workflows are better documented explanations than direct replacement of junior staff by software.

The signal still matters. ADEM’s June figures showed resident jobseekers up 9.7% over a year, with highly qualified jobseekers up 19.1%; accounting, management and banking were among the affected occupations. The European Commission expects employment growth of 1.3% in 2026, below Luxembourg’s historical average.

The Big Four are thus flashing amber rather than red: local headcount growth has stalled, and some work is moving elsewhere, but revenue, audit demand and graduate intake remain positive. The more durable risk for Luxembourg is that future growth creates fewer entry-level jobs inside the country even when the firms themselves continue to expand.
