Accountant in Luxembourg: your fiduciary, from entry to filing.

What does an accountant do in Luxembourg?

A Luxembourg accountant's role goes well beyond data entry. Day to day, they record transactions in double-entry, reconcile bank accounts, track receivables and payables, and prepare VAT returns. At year-end, they prepare the balance sheet, profit-and-loss account and notes, then file the annual accounts with the RCS within the legal deadline.

Beyond bookkeeping, a full-service fiduciary handles tax (corporate income tax, municipal business tax, net wealth tax), payroll and CCSS filings, and advisory: structure selection, optimisation, financing or sale preparation. This continuity, from entry to advice, is what sets a true partner apart from a data-entry provider.

Accountant, chartered accountant, fiduciary, auditor: the differences

"Accountant" describes the bookkeeping function. The "chartered accountant" (expert-comptable) is a regulated title, overseen by the OEC. The "fiduciary" is the firm that bundles these skills and delivers accounting, tax, payroll and domiciliation services.

The "approved statutory auditor" (réviseur d'entreprises agréé) performs the statutory audit: this is separate from bookkeeping and becomes mandatory above certain thresholds. A company cannot entrust both bookkeeping and the statutory audit to the same provider, that is the audit-independence principle.

Your accounting obligations in Luxembourg

Commercial companies must keep regular double-entry books, record all transactions chronologically and without delay, and prepare annual accounts (balance sheet, profit-and-loss account, notes). Supporting documents and books are retained for ten years.

Concerned: sole traders, commercial companies (SARL, SA, SENC, SCS, SCA, cooperative, SE), branches of foreign companies, EIGs and EEIGs, and certain ASBLs and foundations depending on size. Precise obligations vary by legal form, size and sector.

LuxGAAP and the standard chart of accounts

Luxembourg accounting relies on the standard chart of accounts (PCN) and the LuxGAAP framework. Groups may, under conditions, opt for IFRS, particularly when consolidating or raising funds internationally. The framework choice affects presentation, measurement and comparability of the financial statements.

We work in LuxGAAP by default and support conversions or restatements to IFRS when the group structure requires it, in coordination with consolidation.

Filing annual accounts: deadlines and penalties

Annual accounts must be approved by the general meeting within six months of year-end, then filed with the Trade and Companies Register within one month of approval, in practice, within seven months of the closing date. Filing is electronic, via the eCDF platform.

Late or missing filings expose the company to surcharges and administrative penalties. Our role is to anticipate the closing calendar, secure the entries upstream and guarantee on-time filing, "zero delay, zero penalty".

When is an approved statutory auditor required?

A statutory audit by an approved auditor becomes mandatory when a company exceeds, over two consecutive years, at least two of three thresholds: balance-sheet total of EUR 4.4 million, net turnover of EUR 8.8 million, and 50 employees on average. Below that, depending on its form, the company may appoint a commissaire (non-approved control).

We assess your situation case by case and, where relevant, coordinate the auditor's work, while staying strictly on bookkeeping and advisory to preserve audit independence.

How much does an accountant cost in Luxembourg?

Indicatively, hourly rates range from EUR 70 to 150 for standard accounting (bookkeeping, payroll, filings) and EUR 150 to 300 for specialised advisory (audit, tax strategy, M&A). Most SMEs prefer a monthly package, calibrated to transaction volume, VAT, payroll and structure complexity.

Our approach: a firm quote after a short scoping call, no hidden costs, and readable packages. You can estimate your budget with our fee simulator before committing.

How to choose, and switch, accountant

A good accounting partner combines licensing and competence (licensed fiduciary, LuxGAAP/tax expertise), responsiveness (a dedicated contact), pricing transparency and advisory beyond entry. Your international footprint, consolidation or directorship needs also matter.

Switching accountant in Luxembourg is simpler than most think: file audit, data recovery from the outgoing provider, seamless VAT and payroll handover, first reporting by the 15th of the following month. Confidentiality is contractual and traceability complete.

Our approach: an AI-augmented fiduciary

We combine the expertise of a licensed fiduciary (auth. 10077274) with AI-assisted workflows: automated collection, OCR entry, intelligent bank reconciliation. Automation frees time for what matters, decisions and advice, which stay human, supervised and signed.

Concretely, you get reliable, on-time accounts, clear visibility on your numbers, and a single point of contact from formation to consolidation.

Odoo accountant in Luxembourg: software, integrator and bookkeeping

Odoo is a business-management software (ERP) with an accounting module. We operate it for you in Luxembourg: setup, standard chart of accounts, VAT, invoicing and bank reconciliation, then keep your accounts directly inside Odoo, with fiduciary administrator access.

The difference with an Odoo integrator is clear: an integrator configures the tool then steps away, whereas a fiduciary configures Odoo and keeps the accounts inside it, continuously and compliantly. You are not buying an IT project, but accounting delivered inside your software.

We also support useful automation: electronic invoicing, overdue-invoice reminders and cash dashboards, without ever locking your access or your data.
