What is OmniTrust ?
What is the role of a fiduciary?
A fiduciary plays a key role in helping companies manage their accounting, tax, legal and administrative obligations. In Luxembourg, a professional fiduciary offers specialised services such as bookkeeping, preparing tax returns, managing payroll and advising on regulatory compliance. It acts as a strategic partner, letting companies focus on their core business while ensuring financial and administrative matters are handled efficiently and in line with current law.
Why use a fiduciary?
Using a fiduciary brings many advantages to companies looking to streamline their financial and administrative management. A professional fiduciary in Luxembourg has deep expertise in local and international regulations, which guarantees legal and tax compliance. By outsourcing these complex functions, companies can cut operating costs, reduce the risk of errors and benefit from tailored advice to improve financial performance — while freeing up internal resources to focus on strategic growth.
How does a fiduciary work?
A fiduciary operates as a specialised service provider working closely with companies to meet their specific accounting, tax and administrative needs. In Luxembourg, a professional fiduciary typically begins with an in-depth review of the company's situation in order to propose tailor-made solutions. It then implements those solutions — keeping the books up to date, preparing tax returns, managing payroll and providing legal advice where needed. Throughout the relationship, the fiduciary maintains transparent, proactive communication to ensure efficient management that meets current standards.
Peut-on créer une entreprise au luxembourg et travailler en France ?
Oui, mais pour créer une société au Luxembourg en étant non-résident, vous devez prouver une « substance » réelle, c’est à dire un bureau fixe, et nommer un dirigeant qui réside à une distance raisonnable du Grand-Duché pour assurer la gestion journalière. Cela inclut une partie de la France, proche frontière.
This is one of the reasons OmniTrust also offers domiciliation services, from a simple registered address through to providing offices or local directors.
What is a registered address service ?
Find out more about domiciliation... Domiciliation is defined by the law of 31 May 1999 on the domiciliation of companies as a company establishing its registered office with a third party, known as the "domiciliation agent". Only members of certain regulated professions may act as a domiciliation agent — chartered accountants are among those authorised to do so. A company that doesn't need its own premises to carry out its activity may, under certain conditions, choose to domicile with a third party and establish its registered office there.
What is the difference between an accountant and a certified accountant of the OEC ?
The distinction between an accountant and a certified accountant is strictly regulated by law: to practice as a certified accountant, one must be registered with the Ordre des Experts-Comptables, which, as the regulatory body, requires its members to follow specific rules. Although both can handle your day-to-day bookkeeping, their responsibilities differ : unlike their counterpart, a certified accountant possesses in-depth expertise in strategic and tax consulting, can conduct audits and reviews, offer registered office services, or handle the accounting for companies with a balance sheet total exceeding €2.3 million and revenue exceeding €4.6 million.

Why choose a local accountant over a 100% software-based solution ?
Software processes data, but an accountant also takes the context into account. Far from merely performing tasks remotely, our experts are true advisors whom you can turn to whenever you have any questions. In Luxembourg, close relationships and in-depth knowledge of administrative officials allow us to resolve situations that an algorithm cannot handle. What’s more, you don’t have to compromise on process flexibility thanks to our digital tool My OmniTrust.
