Can you tell a little bit about Baker Tilly Luxembourg?
With over 50 years of history, our firm is firmly rooted in the Luxembourg business landscape while also having expanded internationally over the years. We’ve achieved steady, organic growth without relying on mergers or acquisitions and now count nearly 140 professionals in Luxembourg. As part of the Baker Tilly global network—one of the world’s top 10 audit and advisory networks with over 53,000 professionals across five continents—we can support our clients with their international ambitions. In Luxembourg, we provide a full “one-stop shop” of services, including accounting, tax advisory, corporate services, audit, payroll, and HR. We are especially active in the real estate sector, notably in private equity real estate and property development. We also offer a dedicated German Desk, which is highly valued by our German-speaking clients. We also developed a standout Innovation department, fully dedicated to supporting and nurturing start-ups—from incorporation to scale-up. Known for going above and beyond, this team has become a real game-changer on the scene.

"They no longer come to us just for figures — they expect insight."
How are your customers' requirements changing?
Our clients increasingly seek guidance and support to navigate a regulatory and legislative environment that is both fast-changing and complex. They no longer come to us just for figures—they expect insight. They want us to help them interpret key indicators: is their debt-to-equity ratio healthy? Is their working capital sufficient? Are customer payment terms under control, or do they require closer monitoring? In short, we’ve evolved from being a traditional accounting and audit firm into a true business partner. This applies equally to our long-standing Luxembourg SME clients and to international financial companies and investment funds using Luxembourg as their European hub.
What potential threats and benefits do you see?
One of the main challenges today is the growing unpredictability of both economic and geopolitical contexts. Businesses must also adapt swiftly to increasingly complex and evolving international regulations. That said, these challenges present real opportunities. They push us to work more closely with our clients—helping them anticipate regulatory changes, adapt their structures, and improve both operational efficiency and profitability. In this context, we see artificial intelligence as a major opportunity. It enables us to automate certain processes, gain deeper insights from data, and offer even more proactive and strategic advice to our clients. Ultimately, these dynamics strengthen the value of our client relationships and reinforce our role as a trusted partner in navigating uncertainty.
