Corporate taxation in Luxembourg is often seen as a burden. Antoine Rodriguez, tax partner at Fiduo, explains how it can become a genuine management tool for business leaders. Anticipation, a global vision, and sound practices: the keys to securing your business and making better decisions.

What are the main pieces of advice you give to business leaders about their taxes?

The first step is to know exactly where you stand: income, expenses, and net profit. Too often, SME taxation is treated as a yearly exercise, when in fact it is the direct consequence of day-to-day business and even personal decisions. That is why having up-to-date accounting and a clear view of your business is crucial.

Next comes anticipation. A concrete example: one client waited until the very last day to file backdated tax returns from 2019. The result? A five-figure penalty. Had they consulted us earlier, this could have been avoided.

Finally, I advise leaders to fully understand their business model and legal structure. Many risks arise simply because companies operate under the wrong setup for their activity, creating both fiscal and legal exposure.

What are your convictions about taxation?

I firmly believe taxation is not rigid: it depends on each individual situation. Everyone must pay taxes, but there are smarter ways of managing them depending on your goals. The keys are anticipation, reliable information, and thoughtful decision-making.

It is also essential to maintain a global vision. Entrepreneurs often focus on one technical issue, when in fact the broader picture matters: corporate taxation, the owner’s tax obligations, lifestyle, personal wealth, succession, and even sensitive situations such as accidents or divorce. Addressing these early on prevents rushed decisions that could endanger the business.

What is one of the recurring debates you have with your clients?

A common discussion is about shifting from a narrow tax focus to a broader strategic perspective. Sometimes the best tax advice in Luxembourg is precisely not to think only about minimizing taxes.

For example, one client considered relocating to Luxembourg, convinced it was a tax haven. After discussion, it turned out this move did not match either their professional or personal goals. Together, we designed a structure more aligned with their lifestyle and long-term ambitions.

That is what I try to show: taxation should be at the service of the entrepreneur, not the other way around. Smart tax management always stems from a well-thought-out business strategy.
