On 27 February 2025, the Court of Justice of the European Union (CJEU) delivered its judgment in Case C‑18/23, ruling that Poland’s Corporate Income Tax (CIT) exemption—limited to externally managed non-resident investment funds—violates Article 63(1) of the Treaty on the Functioning of the European Union (TFEU). This decision unlocks refund opportunities for internally managed funds in Poland and underscores the EU’s intolerance of de facto discrimination in national tax rules.
Background: The Polish Restriction
Poland’s tax regime grants domestic Collective Investment Vehicles (CIVs)—both UCITS and Alternative Investment Funds (AIFs)—an automatic CIT exemption. By contrast, foreign funds from EU/EEA jurisdictions must satisfy multiple conditions, notably:
- External Management Mandate: The fund must be managed by an entity authorised by Poland’s financial supervisory authority.
- Supervisory Consistency: All Polish funds comply by law; internally managed structures are expressly prohibited under the Polish Law on Investment Funds and AIF Management.
While superficially neutral, this criterion structurally excludes internally managed foreign funds, despite their regulatory equivalence under home Member State laws (e.g., Luxembourg’s SIF regime and UCITS SICAV structures).
Advocate General Kokott’s Opinion
Prior to the Court’s ruling, Advocate General Juliane Kokott (11 July 2024) presented three lines of reasoning:
- No Discrimination Argument: The exemption applies irrespective of domicile—there is no direct discrimination.
- Indirect Discrimination (Rebutted): Even if an effect exists, Member States enjoy autonomy in fund regulation and may justify distinctions on investor-protection grounds.
- Proportionality & Public Interest: Assuming comparability, the external management rule could be justified by effective investor protection and proportionality in risk separation.
Despite these arguments, the CJEU diverged, finding Poland’s rule both discriminatory in effect and lacking an overriding public interest justification.
The CJEU Verdict: Discriminatory and Unjustified
The CJEU’s decision is grounded in established free movement jurisprudence:
- Indirect Discrimination: Conditions specific to domestic market structures—here, prohibiting self-managed funds—create de facto barriers for non-residents.
- Comparability Analysis: Internally and externally managed funds are objectively comparable when:
- Both are subject to regulatory oversight under home-state law.
- Both pursue equivalent investment objectives and supervisory safeguards.
- Rejection of Justifications: Poland failed to demonstrate that the external-management requirement:
- Enhances investor protection beyond existing EU supervision.
- Prevents abuse uniquely tied to internal management formats.
Conclusion: Article 63(1) TFEU precludes national rules granting CIT exemptions exclusively to externally managed funds.
Why This Matters: A Broader EU Trend
This landmark ruling consolidates the CJEU’s stance against “form-over-substance” criteria in tax law. Recent precedents include:
- Case C‑342/20 (Finland): Striking down preferential treatment for contractual funds only.
- Cases C‑478/19 & C‑479/19 (Italy): Invalidating tax breaks for closed‑ended real estate funds alone.
Key takeaway: Any “objective” criterion mirroring domestic market specifics risks invalidation when it disproportionately affects non‑resident operators.
Implications for Internally Managed Funds
Internally managed investors should proactively:
- Reopen Closed Proceedings: Submit formal refund requests within one month of 27 February 2025 to Polish tax authorities—or three months to administrative courts—for overpaid withholding taxes plus interest.
- Initiate New Claims: Leverage the ruling to claim CIT exemptions without restructuring management.
- Assess Limitation Periods: Conduct an urgent review of Polish-sourced income to safeguard reclaim rights.
This ruling paves the way for streamlined processes, potentially reducing litigation burdens and accelerating recovery timelines.
Strategic Considerations for Global Tax Recovery

- Litigation Readiness: Prepare administrative filings and contingency plans for cases nearing statutory deadlines.
Conclusion
The CJEU’s decision in Case C‑18/23 signals a paradigm shift: national tax measures must align with EU freedoms in substance, not just form. Internally managed funds now stand on equal footing to claim withholding tax relief in Poland, reinforcing the principle that equity of access trumps domestic convenience.
