Introduction
On December 19, 2024, the Court of Justice of the European Union (CJEU) delivered a landmark ruling in Case C-601/23 concerning the taxation of dividends and the free movement of capital within the EU. The judgment struck down provisions of the Spanish tax system that resulted in discriminatory treatment of non-resident companies, specifically in Spain. This decision reaffirms the principle that resident and non-resident taxpayers in comparable situations must be treated equally under Article 63 of the Treaty on the Functioning of the European Union (TFEU).
Background of the Case
Credit Suisse Securities (Europe) Ltd (Credit Suisse), a UK-based company with no permanent establishment in Spain, received dividends from a Spanish-resident company in 2017. These dividends were initially subject to a 19% withholding tax (WHT) but were reduced to 10% under the Spain-UK double tax treaty.
Under Spain’s tax regime:
- Resident companies paying corporate income tax (CIT) could treat the WHT as a prepayment and were eligible for a refund if they incurred losses.
- Non-resident companies, however, faced definitive taxation on their dividends, with no refund mechanism available.
Credit Suisse recorded a negative taxable base in 2017, but it could not offset the withheld tax against its liabilities. The company argued that the inability to claim a reimbursement, unlike its resident counterparts, amounted to discriminatory treatment and violated Article 63 TFEU (free movement of capital).
After its claims for reimbursement were rejected by the Spanish tax authorities, Credit Suisse appealed to the High Court of Justice of the Basque Country, which in turn referred the case to the CJEU for a preliminary ruling.
CJEU’s Key Findings and Ruling
The CJEU ruled in favour of Credit Suisse, concluding that Spain’s withholding tax regime for non-residents breached EU law by placing non-resident companies at a disadvantage compared to resident entities. The Court emphasized that the tax system created an unjustified restriction on the free movement of capital as enshrined in Article 63 TFEU.
Spain’s arguments for justification under Article 65 TFEU, which permits certain tax distinctions based on residency, were rejected. The differing tax treatment between residents and non-residents was deemed discriminatory, as non-resident companies had no means to reclaim the withholding tax, despite being in an identical financial position to resident companies eligible for refunds.
Additionally, arguments based on tax collection efficiency, the balanced allocation of taxing rights, and the coherence of the tax system were dismissed, as they could not override the EU’s core principle of non-discrimination. The ruling reaffirmed the fundamental principle that when a Member State taxes both resident and non-resident companies on the same income, it must ensure comparable treatment.
Implications for Businesses and EU Tax Law
1. Impact on Spain and Other EU Member States
The recent ruling invalidates discriminatory aspects of Spain’s tax regime, compelling authorities to revise their approach to non-resident entities. Beyond dividends, this ruling could also influence the taxation of interest and royalties, which will strengthen legal arguments against other discriminatory withholding tax regimes within the EU.
2. Reinforcing the EU’s Commitment to Free Capital Movement
This decision reinforces the CJEU’s stance established in landmark cases like Sofina (C-575/17) and the Danish Cases (C-115/16 and C-299/16), further restricting the ability of EU Member States to impose withholding tax disparities that disadvantage non-resident investors.
As a result, Member States may need to reevaluate their dividend withholding tax policies to align with EU non-discrimination principles, which could drive broader reforms in tax legislation.
3. Implications for Multinational Companies
Multinational businesses operating in the EU and beyond should carefully review their past withholding tax payments to assess eligibility for refund claims.
4. Broader International Tax Considerations
This ruling underscores potential conflicts between EU law and bilateral tax treaties, particularly regarding withholding tax obligations and loss relief mechanisms. It also raises critical questions about the intersection of EU tax law with emerging global tax frameworks, such as the OECD’s Pillar Two rules.
Next Steps for Affected Companies
- Review Past WHT Payments:
Companies that paid Spanish withholding tax on dividends during loss-making years should consider filing refund claims.
- Assess Cross-Border Tax Compliance:
Businesses should evaluate the tax treatment of dividends in other EU countries to ensure compliance with non-discrimination principles.
- Monitor Future Legal Developments:
Spain and other EU Member States may revise their tax laws, so staying informed on new legislative developments is crucial.
- Engage with Withholding Tax experts:
Companies should work with legal and tax professionals to navigate potential claims and adjust future tax strategies.
Conclusion
The CJEU’s ruling in C-601/23 is a game-changer for cross-border taxation in the EU. By declaring Spain’s discriminatory WHT treatment of non-residents illegal, the Court has set a critical precedent that will impact tax policies across the EU.
This case underscores the CJEU’s firm stance against discriminatory tax treatment and will likely lead to significant tax law reforms. Non-resident investors and multinational companies should actively reassess their WHT exposure and consider seeking refunds where applicable.
