Morocco DNEC Expert-Comptable common mistakes
Morocco DNEC Expert-Comptable · Understand the traps and how to avoid them.
In the cas pratique, the candidate recalculates the IS at the standard 20% rate without first testing the reduced 15% rate on the first MAD 300,000 of taxable profit, and without netting the minimum contribution (cotisation minimale) against it.
Under pressure of the integrated case, candidates apply one memorised rate to the whole base; the progressive bracket and the interaction between IS and cotisation minimale are the two points most often skipped in revision, because they are treated as minor details rather than structural rules.
What to do instead
Build a fixed computation template: résultat fiscal (réintégrations/déductions) → base → apply 15% on the first MAD 300,000 and 20% above → compute cotisation minimale on turnover with its own exclusions → compare and retain the higher, crediting any CM already paid. Run the template on three past cases before the exam so the order becomes automatic.
In consolidation or IFRS questions, the candidate records the full goodwill or the full unrealised profit on intra-group transactions instead of eliminating them, and mixes up the parent-company accounts with the consolidated accounts.
Candidates learn consolidation as a set of journal entries to memorise rather than a logic of substitution (the group replaces the parent). When a case adds a non-controlling interest or an upstream sale, the memorised entry no longer fits and the candidate improvises.
What to do instead
Before writing any entry, state in one sentence what the group's economic position is (e.g. 'the group has not sold to itself'). Then apply the elimination to that statement. Practise three variants of the same intra-group sale (upstream, downstream, with NCI) and reconcile the NCI share each time.
The candidate answers a droit des sociétés question by describing the general rule but omits the quorum, majority and convocation formalities specific to the type of company (SARL vs SA) and to the nature of the resolution (ordinary vs extraordinary).
Company law is revised as narrative text; candidates remember that an AGE decides capital changes but not the two-thirds majority on first convocation and the required quorum, because these numbers are learned passively and never tested against a scenario.
What to do instead
Maintain a single comparison table with columns SARL / SA and rows: convocation delay, quorum first and second convocation, majority ordinary, majority extraordinary, who chairs. Recite it from memory weekly and answer at least one scenario per row, stating the consequence of a defective resolution (nullity), not just the rule.
On TVA questions, the candidate treats an export of services or an intra-community operation as a domestic taxable supply, and forgets the deductibility conditions and the declaration deadlines when computing the payable tax.
Candidates focus on rates and bases and treat territoriality and timing as background knowledge. In practice the exam tests exactly the exceptions (exonération avec droit à déduction, autoliquidation, exigibilité), and these are the least drilled items.
What to do instead
For every TVA scenario, answer four questions in writing before computing: where is the operation located, is it taxable or exempt with or without deduction, when does the tax become exigible, and who declares it. Then compute. Build a one-page map of territoriality rules and redo it from blank paper twice.
In audit questions, the candidate lists substantive tests without linking them to the assessed risk of material misstatement, and proposes a sample size or an opinion without justifying it by reference to materiality.
Audit standards are memorised as lists of procedures. Candidates do not practise the reasoning chain risk → assertion → response → evidence → conclusion, so the answer reads as a catalogue and loses the marks allocated to justification.
What to do instead
Write every audit answer as a chain: identified risk, affected assertion, planned response (test of control or substantive), nature/timing/extent, evidence expected, conclusion. Compute and state materiality explicitly (e.g. 5% of profit before tax) before proposing any sample or opinion.
The candidate confuses the missions of the expert-comptable with those reserved by law, and states that the expert-comptable can certify accounts or that the commissaire aux comptes can keep the books of the entity he audits.
The regulatory framework of the profession is revised quickly at the end of the programme and the boundaries between expertise comptable, commissariat aux comptes and audit contractuel are blurred by everyday usage of the word 'audit'.
What to do instead
Draw the three circles (expertise comptable, commissariat aux comptes, audit contractuel) with the incompatibilities written on the overlaps. Learn the specific prohibitions (e.g. the commissaire aux comptes cannot be the accountant of the entity, and cannot receive fees from it for other services that compromise independence) with one concrete example each.
In the soutenance, the candidate presents the technical solution in detail but cannot justify the methodological choices, the alternatives rejected, or the limits and ethical implications of the recommendation.
Candidates prepare the memoir as a technical document and rehearse content, not defence. The jury's questions target judgement, professional scepticism and the reasoning behind choices, which were never written down.
What to do instead
For each major recommendation in the memoir, prepare a one-page defence sheet: the problem, the options considered, the criteria used to choose, the retained option, the risks, the ethical safeguards. Rehearse answering 'why not the other option?' and 'what would change your conclusion?' aloud.
On finance and valuation questions, the candidate discounts nominal cash flows at a real rate (or vice versa), uses the accounting profit instead of free cash flow, and forgets to adjust the discount rate for the entity's actual gearing.
Formulas are memorised in isolation and the consistency conditions between numerator and denominator are never made explicit. Under time pressure the candidate grabs the first rate given in the statement.
What to do instead
Before computing, write a consistency check in the margin: cash flows nominal or real, pre-tax or post-tax, levered or unlevered, currency and date of the flows. Match the discount rate to each of these four attributes, then compute. Redo one DCF and one WACC from a blank page with the check visible.
In management accounting, the candidate computes variances and cost allocations mechanically but does not interpret the result or link it to a decision (price, mix, capacity, make or buy), and mixes fixed and variable costs in the contribution margin.
Management accounting is treated as arithmetic practice. Candidates master the formulas but not the managerial reading, and the exam now asks for the decision implication, not just the number.
What to do instead
End every calculation with two sentences: what the variance or cost means operationally, and what action it triggers. Systematically classify each cost as fixed or variable before computing any margin, and check that the sum of variances reconciles to the total difference.
On droit social and payroll questions, the candidate computes contributions on the gross salary without applying the ceiling, the exonerations and the cap on deductibility of retirement benefits, and ignores the distinction between dismissal for personal reasons and economic dismissal.
Social law is often the last domain revised and is treated as a table of rates. The ceilings, the conditions of exoneration and the procedural steps of dismissal carry most of the marks and are precisely what is skipped.
What to do instead
Build a payroll computation sheet with explicit lines for the ceiling, employee and employer shares, and exonerations, and run it on a salary above and below the ceiling. For dismissal, write the procedure as a dated checklist (convocation, interview, notification, delays, indemnities) and test it on one economic and one personal case.
