CJEU Broadens Anti-Abuse Tests for EU Zero-Rate Dividend Withholding Relief

On 15 October 2026 the Court of Justice of the European Union decided C-203/25 (Neo Group), a reference concerning the EU Parent-Subsidiary Directive's zero-rate dividend withholding tax exemption, holding that the circumstances in which anti-abuse rules may apply to that exemption are broader than previously understood. In practical terms, the judgment signals that a treaty-based zero rate is not a safe harbour: features of a holding arrangement that make it artificial, or the absence of a genuine business purpose, can be scrutinised before the exemption is granted, with the referring national court applying its domestic anti-abuse standard. The only source here is a law-firm alert summarising the decision, so the precise scope of the reasoning, the anti-abuse criterion endorsed and the fiscal conditions at issue should be confirmed against the judgment and any Advocate General opinion before reliance. Why sophisticated counsel should care: structured holding companies, treasury centres and IP-owning groups route dividends through intermediate jurisdictions because the exemption's predictability is a pricing input; a widened anti-abuse perimeter raises diligence cost on new and existing structures and can affect advance rulings, reorganisations and exit planning. Watch for national implementing and administrative responses, further references from other Member States, and any companion challenge to the Directive's zero-rate regime.
