On Thursday 15 January 2026, PwC Luxembourg published its annual review for the fiscal year from 1 July 2024 to 30 June 2025.
The report showed an overall business growth of 5% during the fiscal year, reaching a total turnover of €765.5 million.
PwC said that this was achieved while improving the operating model and investing in advanced technological and innovative capacities, particularly where artificial intelligence (AI) is concerned.
François Mousel, Managing Partner at PwC Luxembourg, said: “PwC remains the leading Big Four in Luxembourg both in size and revenue. While the year ending on 30 June 2025 was not without its challenges, macroeconomic as well as geopolitical, it was a successful year for our firm marked by many solid achievements and enormous transformation so that we can serve our clients better.”
He continued: “Across our lines of service, which saw varied degrees of growth, assurance did very well, driven by audit and broader assurance services, plus major ESG [environmental, social and governance] and sustainability assignments. Advisory’s success was highlighted by resilience in technology, AI and industry sectors, with a main highlight being our recognition as 2025 Microsoft Country Partner of the Year for Luxembourg. Tax’s turnover was boosted by new measures to support Luxembourg’s financial sector and continued investment in innovative, tech-enabled managed services solutions.”
He also noted that the firm had expected 2025 to be a challenging year, with the same outlook extending into 2026. However, he highlighted that the firm remains optimistic in the long term due to continued investment in its transformation, business and people, while stressing the importance of Luxembourg maintaining its competitiveness.
