Case Note: C-382/16 Hornbach-Baumarkt AG v Finanzamt Landau / Zheng Xinyue

1. Facts and Legal Background 

This case concerns the compatibility of Germany’s transfer-pricing adjustment rule under  Paragraph 1 of the Außensteuergesetz (AStG) with the freedom of establishment under Articles  49 and 54 TFEU. The Applicant, German retail group Hornbach-Baumarkt AG, is the parent  company of two Dutch subsidiaries, and the Defendant is Finanzamt Landau, the German Tax  Office. 

Hornbach indirectly owned 100% of two Dutch subsidiaries that faced negative equity and  required significant bank financing (€10M and €14.8M) to maintain operations and construct  new facilities. In September 2002, the bank required comfort letters as a condition for lending.  Hornbach provided the comfort letters gratuitously, committing to maintain its shareholdings,  prevent ownership changes without notice, and fund the subsidiaries to meet liabilities,  effectively guaranteeing the loans. The Tax Office held that such comfort letters contained a  guarantee with economic value and that unrelated parties would require remuneration. It  therefore increased Hornbach’s taxable income based on deemed arm’s-length remuneration  under Paragraph 1 AStG, imputing €15,253 and €22,447. Hornbach argued that comparable  domestic transactions would not trigger adjustments and that the AStG therefore breached the  freedom of establishment. 

Paragraph 1(1) AStG requires income adjustments where non-arm’s-length terms arise in  cross-border dealings; no such correction applies domestically. A “related party” includes at  least a 25% direct or indirect shareholding or the capacity to exercise influence under Paragraph  1(2) AStG. Articles 49 and 54 TFEU regulate and extend the freedom of establishment to  companies. 

2. Issue Before the Court 

The critical legal question was: Does Paragraph 1 AStG, which allows a unilateral income  adjustment solely in cross-border intra-group transactions where arm’s-length conditions are  not met, constitute a restriction on the freedom of establishment? If so, can this restriction be  justified, and is it proportionate? 

3. CJEU Judgment 

The Court held: 

1. The German rule restricts the freedom of establishment because it applies only to cross border related-party transactions, not domestic ones.

2. The restriction can, in principle, be justified by the legitimate objective of safeguarding  the balanced allocation of taxing powers and preventing profit shifting. 

3. However, the rule must satisfy proportionality, meaning taxpayers must be given the  opportunity to demonstrate commercial reasons for non-arm’s-length conditions. 4. Paragraph 1 AStG, as interpreted by national authorities, did not sufficiently allow such  justification; therefore, the German measure risked going beyond what was necessary. The Court thus required the national court to verify whether German law grants taxpayers  a real opportunity to provide economic explanations for the non-arm’s-length conditions. 

4. Analytical Framework 

(A) Fundamental Freedom Involved 

The Court reaffirmed that the freedom of establishment is engaged whenever domestic law  treats foreign subsidiaries less favorably than domestic ones. Because Hornbach-Baumarkt AG  held equity in Dutch subsidiaries and exercised decisive influence, the scenario fell squarely  within Articles 49 and 54 TFEU. 

The German legislation applied only when a taxpayer had a relationship with a foreign  related company, creating a disadvantage for cross-border establishments. The Court  emphasized that situations involving foreign subsidiaries are capable of falling within the  freedom of establishment where the parent company exercises decisive influence consistent  with prior case law, such as Cadbury Schweppes and SGI. 

(B) Discrimination or Restriction 

With respect to the comparability and different treatment, the Court found that the German  legislation constituted a restriction, even in the absence of overt discrimination. The  comparability test focuses on whether domestic and cross-border transactions are treated  differently for aimed purpose pursued ensuring arm’s-length pricing. 

The German measure only empowered tax adjustments when transactions involved foreign  group companies. Domestic subsidiaries, even if supported by the parent without remuneration,  were not subject to similar adjustments. Thus, comparable situations were treated differently.  The Court relied on the reasoning that the arm’s-length principle concerns the prevention of  profit shifting, but that alone does not render domestic and foreign cases incomparable. While  the risk of erosion may be higher cross-border, the parent company's economic rationale— supporting underperforming subsidiaries to protect group value—exists in both settings. 

Therefore, the restrictive effect resulted from differential treatment based on the location  of the subsidiary. 

(C) Justification

2 

Case Note: C-382/16 Zheng Xinyue 12920241150806 

The Court recognized two potential justifications advanced by Germany: (1) Balanced  allocation of taxing powers between Member States. The Court accepted this as a legitimate  aim, as if Member States could not adjust taxable income when intra-group terms deviate from  market conditions, companies could artificially shift profits to lower-tax jurisdictions. (2)  Prevention of tax avoidance or profit shifting. The Court reiterated that measures ensuring  compliance with the arm’s-length standard can be justified where they seek to prevent artificial  arrangements eroding the tax base. 

Notably, the Court did not require the national rule to specifically target wholly artificial  arrangements. Unlike Cadbury Schweppes, the German measure did not require proof of  artificiality, because the aim was broader: ensuring income reflects genuine value creation  consistent with the allocation of taxing rights. Thus, the restriction was justifiable. 

(D) Proportionality 

According to the Court’s proportionality analysis, a restrictive measure must be  appropriate and necessary to achieve the objectives pursued. The Court agreed the AStG rule  was appropriate in targeting profit shifting but questioned the necessity, focusing on two  components: 

1. Requirement that taxpayers be allowed to present a commercial justification The Court emphasized that multinational groups often support subsidiaries for valid  economic reasons, including preserving investment value, ensuring liquidity, or preventing  bankruptcy. These are not artificial arrangements. Thus, for the measure to be proportionate,  taxpayers must have the opportunity to prove that the terms deviate from arm’s length due to  sound commercial reasons. The Court found ambiguity in German law, and from the referring  court’s description, it appeared that such economic justification was not clearly allowed or was  overly restricted. 

2. Proportionality of automatic income adjustments 

The Court found that an automatic upward adjustment without the ability to demonstrate  business rationality exceeds what is necessary to prevent tax avoidance. If a taxpayer can show: (1) the financial support was commercially motivated, (2) it would have been provided under  similar terms to a domestic subsidiary, or (3) it aimed to safeguard group value, then applying  the arm’s-length adjustment mechanically would be disproportionate. Therefore, while the  objective is legitimate, the measure must allow the taxpayer to rebut the presumption of profit  shifting. As the German rule did not clearly allow this, it risked violating proportionality. The  Court left to the national court the task of verifying whether German practice permits such  justification.

5. Conclusion 

C-382/16 Hornbach-Baumarkt refines the CJEU’s treatment of national transfer pricing  rules in light of the freedom of establishment. The Court balanced the legitimate interest of  preventing profit shifting with the protection of economic integration in the internal market. 

On the restrictions, Cross-border intra-group financing is treated less favorably than  domestic equivalents. For possible justifications, combating profit shifting and safeguarding  taxing powers are valid aims. Moreover, States must allow taxpayers to demonstrate  commercial grounds for non-arm’s-length conditions. Automatic adjustments without such a  purpose are disproportionate. The judgment underscores that fundamental freedoms do not  prevent Member States from enforcing arm’s-length pricing, but such measures must be crafted  to respect legitimate business realities and the taxpayer’s right to justify cross-border conditions.
