Case Information
Court: Hoge Raad der Nederlanden (Supreme Court of the Netherlands), Belastingkamer (Tax Chamber)
Case number: 21/04746
Citation: ECLI:NL:HR:2026:736
Applicant: [X] B.V. (referred to in the judgment as 'belanghebbende')
Respondent: Staatssecretaris van Financiën (State Secretary of Finance)
Jurisdiction: Netherlands
Judgment date: 1 May 2026
Judgment Summary
The case concerns supplementary corporate income tax assessments (navorderingsaanslagen) imposed on [X] B.V. for the fiscal years 2007/2008 and 2008/2009. The Inspector disallowed in full the interest deductions claimed by the taxpayer on certain limited-recourse loans (the LR Loans) provided by a Luxembourg entity (LuxCo).
The Court of Appeal (Gerechtshof Amsterdam) had ruled against the taxpayer on all principal issues: it found no sufficient commercial justification for the structure under Article 10a, lid 3, letter a, Wet Vpb 1969; held that the counter-counter-evidence rule of Article 10a, lid 3, letter b, first sentence (final part) was satisfied by the Inspector; denied the deduction for the pre-2008 period on the basis of fraus legis; and found no infringement of EU law.
The Supreme Court dismissed all four grounds of the principal cassation appeal and, as the condition for the conditional cross-appeal was not fulfilled, that cross-appeal lapsed.
Background
[X] B.V. (the taxpayer) is a Netherlands-resident joint-venture company established to give effect to a cooperation between a Netherlands-resident bank (NL Bank) and a France-resident bank (the French Bank) [2.1].
A wholly owned Luxembourg subsidiary of the French Bank, LuxCo, purchased the taxpayer as an off-the-shelf company (plankvennootschap) for the purpose of setting up an investment structure. The structure was implemented in two tranches: the first on 17 August 2006 and the second on 14 March 2007 [2.2].
In the first tranche, LuxCo subscribed for A-shares in the taxpayer for approximately €10 million (95% of nominal share capital) and NL Bank subscribed for B-shares for approximately €500,000 (5% of nominal share capital). NL Bank also contributed €424.5 million as share premium (agio) on its B-shares [2.3.1]. LuxCo simultaneously lent the taxpayer a Super Senior Loan of €75 million, a Senior Limited Recourse Loan of €410 million and a Junior Limited Recourse Loan of €5 million (the latter two collectively the LR Loans) [2.3.2].
The taxpayer deployed the total funds of €435 million in equity and €490 million in debt: (i) €500 million was invested in a third-party variable-rate bond portfolio (obligatieportefeuille), with the variable rate converted to a fixed rate of 4.176% by means of an interest rate swap with NL Bank; and (ii) €425 million was invested in ordinary and preference shares issued by LuxSub, a Luxembourg subsidiary of LuxCo, giving the taxpayer a nominal 15% interest in LuxSub while LuxCo retained 85% [2.3.3, 2.4.1, 2.4.2].
LuxSub was included in a Luxembourg intégration fiscale with LuxCo, under which LuxSub owed tax on its commercial profits to LuxCo under a tax sharing agreement [2.4.1]. LuxSub was financed with €425 million equity and a €175 million profit-sharing bond from LuxCo, and used those funds to purchase third-party variable-rate bonds, again swapped to a fixed rate of 4.176% [2.4.2].
The preference shares in LuxSub were treated as capital in Luxembourg for legal and commercial purposes but as debt for fiscal purposes, making the preference dividend (set at 4.176% of the value of the preference shares including share premium, being €425 million) deductible at LuxSub level in Luxembourg [2.6.1, 2.6.2]. The LR Loans were limited-recourse in that repayment of principal and accrued interest was capped at amounts received by the taxpayer on the preference shares [2.7.1].
In the second tranche (14 March 2007), NL Bank contributed a further €325 million as share premium on its B-shares. LuxCo provided a further Senior B Limited Recourse Loan of €325 million on identical limited-recourse terms [2.8.1, 2.8.2, 2.8.3]. The taxpayer extended its bond portfolio by €325 million (interest rate swap fixed at 4.108%) and acquired additional preference shares in LuxSub for €325 million [2.8.4, 2.9.1]. LuxSub was again financed with €325 million equity and €135 million debt from LuxCo, investing in further variable-rate bonds swapped to 4.108% [2.9.2, 2.9.3].
The joint venture ended on 30 September 2009, when LuxCo purchased NL Bank's B-shares for €750 million and resold them to a Dutch subsidiary of the French Bank [2.10.1]. On 2 October 2009, the taxpayer repaid its debts to LuxCo totalling €815 million (Super Senior Loan €75 million and LR Loans €740 million in aggregate) [2.10.2]. The taxpayer entered liquidation on 30 October 2010 and was dissolved on 31 December 2010 [2.10.3].
In its corporate income tax returns, the taxpayer reported a taxable amount of €5,307 for 2007/2008 and €126,980 for 2008/2009. In both returns it deducted interest on the LR Loans and simultaneously recognised an equal amount of exempt participation income (deelnemingsvrijstelling) on the preference shares in LuxSub: €31.2 million (2007/2008) and €31.1 million (2008/2009). The Inspector initially assessed the taxpayer in accordance with its returns but later raised supplementary assessments disallowing the interest deductions in full [2.11].
Core Dispute
The central question before the Court of Appeal, carried into cassation, was whether interest on the LR Loans was deductible by the taxpayer under the Wet op de vennootschapsbelasting 1969 (Wet Vpb 1969). It was not in dispute that the LR Loans were tainted loans (besmette leningen) within the meaning of Article 10a of that Act [3.1].
The specific issues in cassation were: (i) whether the Court of Appeal had exceeded the limits of the legal dispute and violated procedural rules by allowing the Inspector to invoke the counter-counter-evidence rule (tegen-tegenbewijsregeling) of Article 10a, lid 3, letter b, first sentence (final part) in respect of a period within the fiscal year 2007/2008, having initially restricted its position to the fiscal year 2008/2009 (Middel I); (ii) whether the purpose and scope of Article 10a prevented application of the counter-counter-evidence rule where the interest was subject to a higher rate of tax in Luxembourg than the Dutch corporate income tax rate (Middel II); (iii) whether denial of the interest deduction on the ground of fraus legis was correct for the period 1 October 2007 to 31 December 2007 (Middel III); and (iv) whether the application of Article 10a or fraus legis was precluded by EU law, in particular Article 49 TFEU (Middel IV).
Court Findings
On Middel I (procedural scope of the counter-counter-evidence rule), the Supreme Court held that the Court of Appeal had permissibly found that the Inspector's initial temporal limitation of his reliance on the counter-counter-evidence rule stemmed from an obvious error of law rather than a deliberate choice. Raising the issue of the rule's entry into force on 1 January 2008 fell within the court's power under Article 8:69, lid 2, Awb to apply the law correctly, regardless of whether doing so benefited the taxpayer or the administrative body. Because the taxpayer had been given sufficient opportunity to respond, neither the good procedural order nor Article 8:69 Awb was infringed. Middel I (onderdeel c) failed [4.1.2 to 4.1.5]. Onderdelen a and b of Middel I were dismissed without extended reasoning pursuant to Article 81, lid 1, of the Wet op de rechterlijke organisatie [4.1.5].
On Middel II (whether the counter-counter-evidence rule could apply where the Luxembourg tax rate exceeded the Dutch rate), the Supreme Court held that the historical background to Article 10a, lids 1 to 3, and the legislative history of the counter-counter-evidence rule introduced on 1 January 2008 showed that the rule was intended to limit the absolute safe harbour for interest deduction that had existed since 1 January 2007 (a compensating levy of at least 10%). The rule can therefore apply whenever the tax on the interest income is 10% or higher [4.2.2]. The taxpayer's reliance on paragraph 1.5 of the Decree of 23 December 2005, CPP2005/2662M, and on the principle of legitimate expectation (vertrouwensbeginsel) was rejected on the grounds set out in paragraphs 4.18 to 4.23 of the Advocate General's conclusion [4.2.3]. The Court of Appeal had correctly admitted the Inspector to discharge the counter-counter-evidence burden, and its finding that the Inspector had succeeded in showing that the LR Loans and related legal acts were not predominantly commercially motivated was upheld. The argument that the Court of Appeal had wrongly treated the fiscal mismatch on preference dividends as relevant was based on a misreading of that court's judgment. Middel II failed [4.2.4].
On Middel III (fraus legis for the period 1 October 2007 to 31 December 2007), the Supreme Court confirmed that once interest is not already excluded from deduction under Article 10a, it remains open to deny the deduction on the basis of fraus legis [4.3.2]. The compensating levy in Luxembourg did not prevent a finding of fraus legis arising from artificiality outside the Article 10a structure [4.3.3]. The Article 10a structure was demarcated by, on one side, the loan from the connected entity and, on the other, the legal act performed with the proceeds [4.3.3]. The vennootschappelijke (corporate) Article 10a structure in this case comprised the French Bank, LuxCo, the taxpayer and LuxSub; the corporate and legal relationships involving NL Bank and the acquisition of the bond portfolio fell outside that structure [4.3.4 (sub-paragraphs as numbered in the judgment)]. Acting in conflict with the purpose and scope of the Act as a whole occurs where the levy of corporate income tax is frustrated on a arbitrary and repeatable basis by artificially created interest charges set against artificially created income (profit drainage, winstdrainage), using legal acts that are not necessary for the commercial objectives pursued and that are solely attributable to the overriding motive of achieving the intended fiscal consequences [4.3.4]. The Court of Appeal's findings on artificiality and repeatability were upheld; the existence of a compensating levy in Luxembourg did not block the fraus legis analysis; and neither the norm requirement nor the motive requirement was misapplied. Middel III failed [4.3.5].
On Middel IV (EU law), the Supreme Court referred to and applied the reasoning in its earlier judgment of 16 January 2026, ECLI:NL:HR:2026:60, paragraphs 2.3.2 to 2.4.2, taking into account that Article 10a, lid 3, letter b, was amended with effect from 1 January 2008, and having regard to the Court of Justice of the European Union judgment of 4 October 2024 in X BV, C-585/22, ECLI:EU:C:2024:822 [4.4.2]. As regards fraus legis, the Supreme Court held that the doctrine must be interpreted and applied by the same standard as Article 10a of the Act: the question is whether (part of) a composite set of legal acts has a wholly artificial character and is specifically designed to avoid tax that would normally be due on profits from activities on national territory. Fraus legis therefore does not go further than the concept of abuse in EU law. The Court of Appeal had not erred. Middel IV failed [4.4.2].
Outcome
The Supreme Court declared the principal cassation appeal unfounded (ongegrond) [section 7]. Because the principal appeal did not result in annulment of the Court of Appeal's judgment, the condition on which the conditional cross-appeal (voorwaardelijk incidenteel beroep) had been filed was not fulfilled, and that cross-appeal lapsed by operation of Article 8:112, lid 2, Awb [section 5]. No order for costs was made [section 6].
The effect is that the Court of Appeal's judgment of 30 September 2021 stands: the interest on the LR Loans is not deductible by the taxpayer for either of the fiscal years 2007/2008 or 2008/2009, and the supplementary assessments and interest charges (heffingsrente) are upheld.
Major Issues / Areas of Contention
- Whether the Court of Appeal violated the scope of the legal dispute and the good procedural order (Article 8:69 Awb) by allowing the Inspector to invoke the counter-counter-evidence rule of Article 10a, lid 3, letter b, Wet Vpb 1969 in respect of a period within the fiscal year 2007/2008, having originally limited his position to the fiscal year 2008/2009.
- Whether the counter-counter-evidence rule of Article 10a, lid 3, letter b, first sentence (final part), Wet Vpb 1969 can apply where the interest on the tainted loans is subject to a compensating levy in Luxembourg at rates (29.63% and 28.59%) exceeding the Dutch corporate income tax rate of 25.5%.
- Whether the Inspector succeeded in discharging the counter-counter-evidence burden by showing that the LR Loans and related legal acts were not predominantly commercially motivated, having regard to the fiscal mismatch arising from the hybrid treatment of preference shares in LuxSub as deductible at LuxSub level but exempt at the taxpayer level under the participation exemption (deelnemingsvrijstelling).
- Whether, for the period 1 October 2007 to 31 December 2007 (before the counter-counter-evidence rule was in force), the interest deduction on the LR Loans must be refused on the ground of fraus legis (wetsontduiking) because the artificially created interest charge was set against artificially created income to drain profits and frustrate Netherlands corporate income tax on the bond portfolio.
- Whether the existence of a compensating levy on the interest in Luxembourg precludes application of fraus legis in relation to legal acts falling outside the Article 10a structure.
- Whether application of Article 10a, lid 3, letter b, Wet Vpb 1969 and/or fraus legis is precluded by Article 49 TFEU (freedom of establishment) and whether the EU law concept of abuse (wholly artificial construction) sets a higher threshold than the Netherlands statutory and judge-made anti-avoidance rules in issue, in the light of the CJEU judgment in X BV, C-585/22, ECLI:EU:C:2024:822.
- Whether the contre-contre-preuve rule introduced on 1 January 2008 has immediate effect and therefore applies to the portion of the broken fiscal year 2007/2008 falling on or after 1 January 2008.
