Chartered accountant in Luxembourg

3 partners, many years of expertise to advise you

Atlas Fiduciaire is a privately-owned Luxembourg firm specializing in accounting and tax services, as well as legal support (in collaboration with a law firm).

We assist companies, self-employed professionals, entrepreneurs, family groups, as well as alternative actors (Private Equity, Real Estate, Private Debt, and Infrastructure).

Founded by three experienced professionals – Franca, Olivier, and Renaud – with complementary backgrounds (lawyer at the Luxembourg Bar, certified auditor and chartered accountant registered with the OEC, and former tax partner at a Big Four firm), Atlas brings together a rare combination of expertise, enabling the firm to offer clients a comprehensive and integrated perspective.

Atlas Fiduciaire Luxembourg

Our approach is based on a simple belief : to provide top-quality service at a fair price, while building strong and lasting human relationships.

What sets us apart is our perspective on the profession : beyond numbers and obligations, we place the relationship with our clients and their priorities at the heart of everything we do.

A committed partner

Behind every structure, every transaction, there are challenges, projects, and, above all, people. We firmly believe that what truly makes the difference is not just technical expertise, but how it is applied in service of our clients.

That’s why we operate with a long-term partnership approach, engaging personally alongside our clients every step of the way.

Availability & trust

This translates into genuine availability, direct communication, and a constant drive to simplify your daily operations. We believe that trust and transparency are the keys to a successful collaboration.

Atlas Fiduciaire also embodies a distinctive corporate culture : we believe this is possible to work seriously without taking ourselves too seriously. We prioritize straightforward, honest, and lasting relationships, where expertise never outweighs attentive listening and mutual respect.

Strong and diverse experience

With over 25 years of experience each, we have worked both in large firms and international groups as well as in our own practices. This dual perspective allows us to combine the rigor and expertise of major organizations with the agility and closeness of human-sized structures.
