CJEU, judgment of 21 June 2012 — Joined Cases C-80/11 and C-142/11, Mahagében and Dávid, ECLI:EU:C:2012:373 · Full text (PDF)
The case
Two Hungarian disputes. Mahagében Kft. bought acacia logs from a supplier which declared all the invoices and paid the tax; the authority nonetheless refused the deduction, reasoning that the supplier had held insufficient stock and no suitable lorry, and that Mahagében had breached its duty of care by failing to check whether the supplier was a taxable person with the goods at its disposal (paras 16–19). Mr Dávid had construction work carried out through subcontractors; the work had undisputedly been performed, but it could not be established which undertaking had employed the workers listed, so the authority treated the invoices as fictitious and additionally alleged a lack of diligence (paras 24–27); in a second transaction the subcontractor was already in liquidation by the time of the audit (para 28). Both referring courts asked whether this refusal practice was compatible with the VAT Directive.
The court’s reasoning
The Court starts from the right of deduction as a “fundamental principle” and an integral part of the VAT machinery which cannot, in principle, be limited (paras 37 et seq.); whether the tax on earlier stages was actually paid is irrelevant (para 40). Refusal is available only on the Kittel conditions: where it is established, on objective factors, that the taxable person knew or should have known that his transaction was connected with evasion committed by the supplier or another trader at an earlier stage of the chain (para 45). Penalising, by refusal, a taxable person who neither knew nor could have known is incompatible with the deduction regime — a system of strict liability would go beyond what is necessary to protect the public exchequer (paras 47 et seq.). Then comes the pivotal evidential proposition: since refusal “is an exception to the application of the fundamental principle constituting that right, it is for the tax authorities to establish, to the requisite legal standard, the objective evidence” from which knowledge or constructive knowledge can be concluded (para 49).
On verification duties, the Court differentiates. Which measures may reasonably be demanded depends essentially on the circumstances of the case (paras 53 et seq., 59). Where there are indications of irregularity or fraud, a prudent trader may, depending on those circumstances, be obliged to make enquiries about the party from whom he intends to buy (para 60). What the administration may not do is require, as a general matter, that the taxable person verify that the issuer of the invoice was a taxable person, had the goods at his disposal, was in a position to supply them and had met his VAT declaration and payment obligations — or that he hold documents to that effect (para 61). Controls of that kind are the tax authorities’ own task (para 62); otherwise the authority would be transferring “its own investigative tasks” to taxable persons (para 65).
Where the judgment sits in the case-law
The decision operationalises CJEU, judgment of 6 July 2006 — Joined Cases C-439/04 and C-440/04, Kittel and Recolta Recycling, in two directions: it assigns the burden of proving knowledge or constructive knowledge expressly to the tax authority for the first time (para 49), and it draws a firm line against offloading official control functions onto businesses (paras 61 et seq., 65). It thereby became the reference point of the entire subsequent case-law — from CJEU, judgment of 6 December 2012 — C-285/11, Bonik, through CJEU, judgment of 11 November 2021 — C-281/20, Ferimet, to CJEU, judgment of 1 December 2022 — C-512/21, Aquila Part Prod Com, and CJEU, judgment of 11 January 2024 — C-537/22, Global Ink Trade, which derive the graduated diligence standard (“heightened care where there are indications, but no complex and far-reaching checks”) directly from Mahagében. For German practice it supplies the EU-law benchmark for every application of Section 25f of the VAT Act.
Academic commentary
Heidner underlines, in the commentary on Section 25f, the EU-law framework under which the burden of establishing the facts lies with the tax administration (Heidner, in: Bunjes, UStG, 24th ed. 2025, § 25f Rn. 9); Kraeusel situates the limits of verification duties within the commentary on the deduction provision (Kraeusel, in: Reiß/Kraeusel/Langer, UStG, § 15 Rz. 690 et seq.). Spilker builds on this line his call for a narrow, EU-law-conform application of the German refusal provision (Spilker, UR 2023, 589 (590)); Wäger traces the practical development of the refusal case-law to the present day (Wäger, UR 2025, 81 (109 et seq.)).
Three levels — kept strictly apart
Operative holding: Articles 167, 168(a), 178(a), 220(1) and 226 of Directive 2006/112 preclude a national practice of refusing deduction on account of irregularities on the part of the invoice issuer, where the authority does not establish, on objective evidence, the taxable person’s knowledge or constructive knowledge (para 50); nor may refusal rest on the trader’s failure to satisfy himself as to the issuer’s circumstances or to hold documents beyond the invoice (para 66). Administrative practice: Sec. 25f.1 of the German VAT Application Decree (UStAE, Federal Ministry of Finance circular of 15 June 2022 — III C 5 - S 7429-b/21/10003 :001, Federal Tax Gazette I 2022, 1001) acknowledges the administration’s burden of establishing the facts and works with risk indicators intended to trigger occasion-based care. Our conclusion for the defence: In our assessment Mahagében is the sharpest weapon against the tacit reversal of the burden of proof common in audit practice: questionnaires demanding blanket supplier vetting invert the rule-and-exception relationship and can be attacked against the yardstick of paras 61 et seq.
Levers for the defence
- Pin down the burden of proof: every refusal decision must be measured against whether the authority has established the objective factors of knowledge or constructive knowledge “to the requisite legal standard” (para 49) — suspicion and chain contamination are not enough.
- Reject blanket duties: demands for across-the-board verification of the supplier’s taxable status, control of the goods, capacity to supply and tax compliance are contrary to EU law (para 61); such reproaches in audit reports can be countered head-on.
- Document the occasion-based trigger: verification duties arise under para 60 only where there are indications; the defence should evidence that no red flags existed at the time of purchase — or that existing signals were acted upon.
- Run the control-transfer argument: where the administration in effect shifts its own investigative work onto the business, para 65 bites — a structural argument against overstretched “diligence catalogues”.
- Highlight a compliant upstream stage: in Mahagében itself the supplier had declared and paid (para 16); where no tax loss is shown, then — as our own assessment — a plausible nexus to evasion is missing from the outset.

FAQ
Must a business comprehensively vet the tax reliability of every supplier?
No. The Court expressly prohibits the administration from requiring, as a general matter, that the trader verify the invoice issuer’s status as a taxable person, his control of the goods, his ability to supply and his declaration and payment record, or hold documents on those points (para 61). Controls of that kind are the tax authorities’ own responsibility (paras 62, 65). Occasion-based enquiries may, however, be warranted where concrete indications of irregularity exist at the time of purchase (para 60). A graduated, documented verification system reflects precisely that distinction.
What must the tax authority prove before it may refuse the deduction?
It must establish, on objective evidence and to the requisite legal standard, that the trader knew or should have known that the specific transaction was connected with evasion at an earlier stage of the chain (paras 45, 49 et seq.). The mere finding of irregularities at the supplier or its own suppliers does not suffice (paras 47, 50). Absent that proof, the deduction stands as the fundamental principle. Later case-law — notably Aquila Part Prod Com — has additionally banned reliance on presumptions in express terms.
