Annual accounts in Luxembourg: approve, file, meet the deadlines.

What exactly has to be filed?

The annual accounts are not a single document but an inseparable set: the balance sheet, the profit and loss account and the notes. The notes are not an accessory; they carry the information without which the figures cannot be interpreted, notably the valuation methods applied, off-balance-sheet commitments, relations with affiliated undertakings and post-closing events.

Depending on the company's size category, a management report and, where applicable, the report of the control body are added. Small companies benefit from reduced formats and exemptions; companies exceeding two of the three criteria of EUR 7.5m total balance sheet, EUR 15m net turnover and 50 employees fall within statutory audit by an approved statutory auditor.

Filing itself is electronic, with the Trade and Companies Register, and financial data is transmitted in structured form through the eCDF platform. The package filed must match the accounts approved by the meeting exactly: any divergence, even in presentation, exposes the company to a correction request. The accounting framework, the standard chart of accounts and the presentation formats are covered on our dedicated balance sheet page.

The legal calendar: six months to approve, seven to file

Two deadlines run in sequence and add up. The first concerns approval: the general meeting must approve the annual accounts within six months of the financial year end. The second concerns filing: the approved accounts must be filed with the Trade and Companies Register within one month of that approval. Together they set the overall deadline at seven months at the latest after the closing date.

For a financial year ending on 31 December, that means a general meeting held by 30 June at the latest and a filing completed by 31 July at the latest. Holding the meeting early does not extend the filing window: a company approving its accounts in March has one month, not four.

In practice, delay rarely comes from a decision. It comes from a chain: a closing that slips because a reconciliation is unsupported, a meeting postponed because a shareholder is unavailable, a filing forgotten because nobody tracks the one-month window. We break that chain by setting the milestones in advance and driving each step rather than absorbing the final deadline.

Who approves the accounts: general meeting and discharge

Approval of the annual accounts belongs to the general meeting of shareholders, not to the management body. That separation is not a formality: it is the basis of the discharge, the decision by which the meeting waives any claim against the managers or directors for the year under review.

A validly granted discharge presupposes that the meeting was properly convened, that it had the accounts and reports before it, and that the minutes faithfully reflect the resolutions adopted, including the allocation of the result. Approximate minutes drafted after the fact for the purposes of a filing weaken precisely the protection they are meant to give management.

In a single-shareholder company, the sole shareholder exercises the powers of the meeting and records decisions in a register. Simplifying the form removes neither the obligation to decide nor the obligation to trace that decision. We prepare the convening notices, resolutions and minutes, and archive them alongside the accounts for the year.

Catching up on unfiled financial years

A company several years behind on its filings is not stuck. Catching up is possible, but it is done one financial year at a time and in chronological order: each year must be closed, approved by a meeting and filed separately. Three years cannot be caught up with a single filing.

The real work usually sits upstream of the filing. Bookkeeping that has been interrupted has to be rebuilt, bank evidence recovered, opening balances reconciled with the last properly filed year, and missing corporate decisions reconstituted. That is the longest part, and the part that determines the quality of the outcome.

The second strand is tax. Unfiled accounts almost always come with unfiled tax returns and therefore with assessments issued on an estimated basis. Regularising the register without regularising the tax position leaves the company half compliant. We handle both in the same file, sequencing the filings so that the figures on the register and the figures in the returns agree.

This work has value beyond compliance: it makes the company financeable, sellable and auditable again. Due diligence always stalls on missing financial years.

What late filing actually costs

The direct cost is an administrative surcharge: late filing of annual accounts with the Trade and Companies Register triggers increased fees, rising as the delay lengthens. That surcharge is entirely avoidable and buys nothing.

The indirect cost is heavier. Unfiled accounts are publicly visible: the register can be searched by anyone. A bank assessing a credit facility, an investor running due diligence, a client vetting a supplier, a landlord testing solvency, all of them see the gap. The delay then reads as a governance signal rather than a missing formality.

The extreme cost is structural. The law of 28 October 2022 introduced an administrative dissolution procedure without liquidation, targeting companies with no activity and no assets that seriously breach legal requirements. Prolonged failure to file accounts is, in practice, one of the signals that draws attention to a dormant and non-compliant company.

Measured against those consequences, the cost of a properly driven closing is marginal. It is one of the few compliance items where the expense avoided is systematically smaller than the risk taken on.

Annual accounts and tax: one continuous chain

The annual accounts do not end at the filing. The accounting result determined at closing is the starting point, after adjustments, for taxable income and for corporate income tax, municipal business tax and net wealth tax. The figures filed with the register and the figures declared to the tax authorities must agree.

That consistency is built at closing, not afterwards. Judgements made on depreciation, provisions and inventory valuation translate immediately into tax. Handling them in one file, with one contact, avoids the discrepancies the authorities pick up later.

Financial Services Accountant Luxembourg S.à r.l.-S operates as an accountant in Luxembourg. The firm holds two business permits issued by the Luxembourg Ministry of the Economy: no. 10077274/0 for the activity of accountant, and no. 10077274/2 for activities ancillary to the profession of chartered accountant within the meaning of article 1 of the amended law of 10 June 1999. For anti-money-laundering and counter-terrorist-financing purposes, accounting professionals other than chartered accountants fall under the supervision of the AED. These permits do not confer the title of chartered accountant or statutory auditor. We take on the full chain: bookkeeping, closing, general meeting, filing with the register and tax returns, on a calendar tracked throughout the year.
