Annual accounts filing in Luxembourg: deadlines and late filing

Annual accounts turn the bookkeeping for a financial year into an approved and public record. For a Luxembourg capital company, the sequence normally moves from closing the books to shareholder approval and then to electronic filing with the Trade and Companies Register, or RCS.

The official filing guidance explains which entities are in scope and how the electronic process works. The legal form, size and audit status determine which documents accompany the accounts, but they do not remove the need to organise the calendar early.

The filing obligation

Luxembourg capital companies such as an SARL or an SA generally file annual accounts with the RCS. Other legal forms can have different publication duties, so the filing package must follow the entity’s own statutory regime.

The filing makes the published documents available through the register. Banks, investors and service providers may rely on that public record during onboarding or due diligence. A missing year can therefore create practical questions even before any legal consequence is considered.

The approval and filing sequence

The ordinary timetable contains two connected deadlines. The competent corporate body approves the accounts within six months after the financial year-end. The approved accounts are then filed within one month, with an overall limit of seven months after year-end.

For a company closing on 31 December, the sequence is as follows.

Step	Latest ordinary date
Financial year-end	31 December N
Approval of the annual accounts	30 June N+1
RCS filing	31 July N+1

The one-month period does not extend the seven-month limit. Late internal approval therefore leaves less time for the electronic filing rather than moving the final date.

The documents in the filing package

The annual accounts form the core of the filing. Depending on the entity, the package may also include notes to the accounts, a management report and an auditor’s report. Size-based presentation or publication options can change the level of detail made public.

The corporate decision approving the accounts and allocating the result must match the final accounting figures. Any dividend decision should therefore be considered together with the Luxembourg distribution rules before the filing is completed.

The electronic process and eCDF

Filing is made electronically through the Luxembourg Business Registers. Entities covered by the standardised accounting-data process first prepare or validate the relevant financial data through eCDF. Supporting documents are then attached in the format required for the RCS submission.

eCDF preparation does not replace corporate approval. It converts the final accounting information into the required filing structure. A reliable accounting process therefore reconciles the signed accounts, the approved result and the data sent electronically.

The surcharge for late filing

Late filing increases the amount charged for publication. The coordinated filing-fee regulation sets the surcharge by reference to the month in which the filing occurs.

Filing time after year-end	Surcharge excluding VAT
Eighth month	EUR 50
Ninth to eleventh month	EUR 200
From the twelfth month	EUR 500

These amounts are filing-fee surcharges. They are not criminal fines. Each late annual filing is assessed separately, so several missing years can produce several surcharges.

Separate consequences of non-publication

The filing surcharge is only one part of the legal framework. Article 1500-2 of the consolidated Companies Law provides for a criminal fine of EUR 500 to EUR 25,000 for directors or managers who fail to submit or publish the accounting documents covered by that provision. Any application of the offence depends on its legal conditions and is distinct from the administrative filing charge.

Persistent non-publication can also support court proceedings. The Luxembourg judiciary identifies repeated failure to publish annual accounts as a breach that may justify compulsory dissolution and liquidation. The court assesses the seriousness of the situation, so one late filing does not cause automatic dissolution.

Bringing an overdue file up to date

Each missing financial year requires its own annual accounts, corporate approval and filing. A later filing does not replace an earlier missing year, and the late-filing surcharge is assessed separately for each set of accounts.

The accounting result must remain consistent with the related tax return, the allocation decision and any distribution. Electronic acceptance by the RCS confirms receipt of the filing, not the accuracy of its underlying figures.

The published financial year and attachments must therefore match the approved accounts.

Conclusion

The ordinary Luxembourg sequence is clear. Annual accounts are approved within six months, then filed within one month and no later than seven months after year-end. eCDF and the RCS filing complete the electronic publication process where they apply. Late filing triggers a surcharge, while serious or repeated non-publication can engage separate legal consequences.
