Frequently asked questions

What is the difference between a fiduciary accountant and a company accountant?
A company accountant keeps the books of a single entity whose flows they know fully. A fiduciary accountant manages a portfolio of several client companies, constantly switching sectors, and becomes their single point of contact: combining accounting technique, VAT, deadline discipline and client relationships.
How many files does a fiduciary accountant handle?
It depends on company size and service level. An experienced profile often handles fifteen to thirty files, more for simple structures such as certain holdings, fewer for complex groups with VAT, payroll and consolidation. Automating data entry increases this capacity.
Do you need to master English?
Yes, in most Luxembourg fiduciaries. The client base is international and many exchanges, documents and reports are in English, sometimes German. French remains a common working language, but FR/EN bilingualism clearly broadens opportunities and pay.
Can you become a fiduciary accountant after a career change?
Yes. Many profiles join a fiduciary after experience in industry or an accounting qualification. The key is mastering Lux GAAP, Luxembourg VAT and the tools (BOB50, Odoo, eCDF, LBR). A structured firm supports the build-up of skills.
