Accruals and accrued income in Luxembourg: cut-off

When must accruals and accrued income be booked in Luxembourg?

Accruals and accrued income in Luxembourg are booked at the balance sheet date as soon as the charge or the income relates to the closed year, regardless of the date of payment or collection: article 51 of the amended law of 19 December 2002 requires charges and income to be attached to the financial year the accounts relate to.

The two entries mirror each other and follow the same logic. An accrual records a liability whose invoice has not arrived: electricity for the last quarter, fees for a completed assignment, an insurance premium already due, a bonus earned by an employee. Accrued income records the matching receivable, income already earned that nothing has invoiced yet: a commission due, rent that has run, an assignment finished whose invoice will go out in January.

The prudence principle completes the rule without contradicting it. Only profits realised at the balance sheet date may be recorded there, yet liabilities arising in the course of the financial year or of a previous one must be taken into account even where they become known only between the closing date and the date the balance sheet is drawn up. The asymmetry is deliberate: a liability discovered in March belongs to the year closed in December, while income still uncertain does not.

Accrual or provision for liabilities and charges: where is the line?

The line between an accrual and a provision for liabilities and charges in Luxembourg is drawn by uncertainty: a liability determined as to its amount and its date is a liability, while a liability that is probable but undetermined on either point is a provision.

The amended law of 19 December 2002 defines the provision by that very uncertainty: it is intended to cover losses or debts clearly circumscribed as to their nature which, at the balance sheet date, are either probable or certain but undetermined as to their amount or as to the date on which they will arise. The law also allows provisions intended to cover charges originating in the financial year or in a previous one. Two limits frame the item: its amount may not exceed what is needed, and a provision may not be used to correct the value of an asset.

The practical test is short and is run with the documents in hand. Where the amount can be computed, because a contract, a tariff, a consumption statement or a timesheet gives it, the accrual is required and the item is a liability. Where the amount depends on a future event, a negotiation or a court ruling, the item is a provision, whose regime our article on provisions for liabilities and charges sets out. Filing a computable liability among provisions is not neutral: the balance sheet total does not change, but the reader of the accounts loses the information that the expense is earned and quantified.

Accrual or prepayment: two items nothing brings together

An accrual and a prepayment are the reverse of one another in Luxembourg: the first is an expense of the year that nobody has invoiced yet, the second an expense already invoiced and paid that belongs to the following year.

The difference shows in the balance sheet, and it is structural. Accruals join creditors, where the layout separates tax and social security debts, then other creditors split according to whether their remaining term is one year or less, or more than one year. The liabilities-side "Prepayments and deferred income" item does not host them: it carries income received before the balance sheet date but attributable to a later financial year. Symmetrically, accrued income joins debtors, while the assets-side "Prepayments and accrued income" item carries expenses paid in advance.

A point of method applies to the layout itself.

The names and ranking of the items cited above are those of the original balance sheet layout in article 34 of the amended law of 19 December 2002; since then, the form and content of the layouts have been set by the grand-ducal regulation of 18 December 2015, which follows the horizontal balance sheet model of article 10 and annex III of directive 2013/34/EU, as question and answer 16/010 of the Commission des normes comptables explains. The structure described remains that of the Luxembourg annual accounts, but the reference to check before any setup is the 2015 regulation.

Which standard chart of accounts accounts carry these entries?

In Luxembourg, no account of the standard chart of accounts is labelled "accruals" or "accrued income" in the sources consulted: these entries sit in the third-party accounts of class 4, next to the liability or the receivable they extend.

The structure of class 4 is known. The standard chart of accounts annexed to the grand-ducal regulation of 10 June 2009 places tax and social security debts in heading 46, other creditors in heading 47 and the regularisation accounts in heading 48, the last carrying charges to be carried forward in 481 and income to be carried forward in 482. Accrued interest appears in 41213 on the receivables side, and the draft regulation published by the Chamber of Commerce renames that account "interest receivable" while placing dividends and interest payable in 47221.

Two reservations call for caution before any setup. The applicable chart is the one determined by the grand-ducal regulation of 12 September 2019, published in Mémorial A631, for financial years beginning on or after 1 January 2020, its chapters on the operation of the chart and on the bridge table taking effect on 4 January 2021; its annex is not readable from our editorial environment. Besides, a bill consulted proposes deleting the accrued interest accounts, including 41213, on the ground that public users of the data did not use them directly, without the adopted text having been verified. The standard chart of accounts itself is structured in seven classes.

What documents support an accrual in Luxembourg?

An accrual in Luxembourg is supported, in the absence of an invoice, by a dated document establishing both its existence and its computation: a contract, a purchase order, a consumption statement, a timesheet, a balance confirmation or a message from the provider quantifying the completed assignment.

The general rule is known and the practice follows from it. The Guichet.lu portal states that an invoice serves as the supporting document for accounting entries; at the closing date it is precisely that document which is missing, so it has to be replaced by dated evidence kept with the closing file. Accounting documents are kept for ten years, reduced to five years in case of liquidation, in electronic or paper form, the place of retention being Luxembourg.

What remains is not to confuse a liability that has arisen with a future commitment. The Commission des normes comptables restates that only liabilities arising in the course of the financial year or of a previous one enter the balance sheet: rent for a future period, for instance, is a commitment and not an accrual.

Significant financial commitments not shown in the balance sheet must appear in the notes individually, with the nature and business purpose of the arrangements not included in the balance sheet and their financial impact. We regularly see an accrual booked for a contract signed in December whose performance starts in February: the expense is certain, but the liability has not arisen.

Is an accrual deductible in the year it is booked?

In Luxembourg, an accrual properly booked is deductible in the financial year it belongs to, through the link between the tax balance sheet and the commercial balance sheet: the tax balance sheet keeps the accounting values where the tax valuation rules do not prescribe a given amount.

Article 40 of the amended law of 4 December 1967 on income tax carries that rule: where the tax valuation rules do not require a given amount, the tax balance sheet must keep the values of the commercial balance sheet, or stay as close to them as the tax rules allow. The Guichet.lu portal sums it up by stating that the tax balance sheet is derived from the commercial balance sheet and is in principle identical to it, unless a tax rule provides otherwise, which then prevails. The consequence is direct: a sloppy cut-off is not fixed in the return, it is fixed in the accounts.

The symmetry on the income side deserves a second reading before any temptation to defer. Guichet.lu states that receivables acquired which have become certain in principle and in amount are taken into account even where they have not yet been settled; sales belong to the year in which they were made, services to the year in which they were completed. Accrued income is therefore not a presentation choice, it is the consequence of a receivable acquired. The mechanism is the one at work in intra-group loan interest accruals, where the charge and the income answer each other on both sides.

What cut-off mistakes do we see on engagements?

Three mistakes recur in files taken over: the accrual missed for want of an invoice, the computable liability filed as a provision to avoid quantifying it, and accrued income never reversed at the opening of the following year.

The first is the most common and the easiest to prevent. A company that waits for the invoice before booking the charge mechanically moves an expense from one year to another, which distorts the result in both directions and, through the link with the tax balance sheet, the taxable base.

The useful habit fits in a closing list: recurring suppliers with no invoice received, completed assignments not yet invoiced, accrued interest, holidays earned and not taken, bonuses decided, consumption for the last month, and the closing foreign exchange differences, which belong to the same exercise. The list is reused from one year to the next and compared with the previous year's actuals.

The other two are quieter. Filing a computable liability as a provision removes from the accounts information they were meant to carry, and the provision often survives several years with nobody picking the monitoring back up. Accrued income left unreversed produces double counting: the income is recognised at the closing date, then a second time when the invoice is issued, and the gap only shows when turnover is reconciled with the returns. The check is plain: at the opening of the following year, every cut-off account must be cleared by the final document, and any residual balance must be explained before the accounts are approved.

Five points could not be verified against an official source at this date. The primary texts first: the domains guichet.public.lu, legilux.public.lu, impotsdirects.public.lu, cnc.lu and cc.lu are blocked by the network proxy of our editorial environment, and those pages were read through indexed extracts using a search restricted to official domains; the statements above reproduce those extracts without extrapolation.

Next the annex to the standard chart of accounts in force: the numbering cited is that of the 2009 chart and of the draft published by the Chamber of Commerce, and the account-by-account correspondence with the annex to the regulation of 12 September 2019 could not be established, hence the reservation carried in the table. Next the actual deletion of account 41213 for accrued interest, proposed in a bill whose adopted text could not be read.

Next the exact names and ranking of the items in the balance sheet layout in force: they are taken from the original layout in article 34, the regulation of 18 December 2015 not having been consulted. Lastly the very existence of an account in the standard chart of accounts expressly labelled "accruals" or "accrued income": no source consulted mentions one, which does not prove there is none. These points can be verified on legilux.public.lu, on cnc.lu and on impotsdirects.public.lu.

This article states the law as it stands at the date of publication and is not personalised legal or tax advice: the characterisation of a year-end mismatch, the choice between a liability and a provision, the account used and the deductibility of the charge depend on the documents available, on the accounting framework applied and on the company's own situation.
