In a landmark decision that could have significant implications for investment funds across Europe, the Court of Justice of the European Union (CJEU) has ruled that Poland's tax exemption policy, which only applies to externally managed investment funds, breaches EU law.

On February 27, 2025, the Court delivered its judgment in case C-18/23, finding that the Polish legislation's restriction violates the free movement of capital under EU law - a fundamental freedom guaranteed by the Treaty on the Functioning of the European Union (TFEU).

Case Background

The case concerned a Luxembourg-based specialized investment fund that was internally managed by its board of directors. Under Polish tax rules, income generated in Poland by investment funds is exempt from corporate income tax only if the fund is externally managed by entities authorized by the competent financial market supervisory authorities.

The Luxembourg fund, despite being authorized by the Luxembourg Financial Sector Supervisory Commission and having its board registered as an alternative investment fund manager, was denied the tax exemption solely because it was internally managed rather than externally managed.

The Court's Reasoning

The CJEU examined whether this treatment constituted discrimination under EU law. While acknowledging the restriction was not directly discriminatory (as it applied regardless of the fund's residence), the Court found the rules created de facto discrimination against cross-border situations.

CJEU Ruling: A Violation of Free Movement of Capital

Contrary to the earlier opinion of Advocate General Kokott, the CJEU ruled in favor of the plaintiff, finding that while the restriction was not directly discriminatory (as it applied regardless of the fund's residence), the rules created de facto discrimination against cross-border situations. Thus, Polish tax rules were found to indirectly discriminatory against non-resident internally managed funds. Key takeaways from the ruling include:

1. Indirect Discrimination

   The tax exemption does not explicitly discriminate based on the fund’s residence, but the requirement of external management de facto favors domestic funds.

2. Restriction on Capital Movement
   

   By denying tax advantages to internally managed funds solely based on their management structure, Poland’s tax regime creates a barrier to cross-border investments.

3. Objective Comparability
   

   The Court rejected Poland’s argument that internally and externally managed funds are not objectively comparable. The CJEU emphasized that Poland’s policy goal of investor protection could be achieved regardless of the fund’s management model.

4. Lack of Justification

   The investor protection rationale used by Poland was deemed insufficient to justify the restriction. The CJEU highlighted how the Polish government failed to explain how denying a tax exemption to internally managed funds would ensure investor protection. Additionally, the Polish government argued the prevention of abuse justification, however the Court highlighted that the defendant failed to explain and establish a link between the management form and the risk of abuse. 

Immediate Implications for Taxpayers

This ruling opens the door for internally managed investment funds to reclaim withholding tax collected on income from Polish investments. Fund managers should note the following action items:

• Polish withholding tax reclaims: Internally managed funds should review their Polish investments and consider filing refund claims.

• Time-Sensitive Action Required: Requests to reopen closed cases must be filed with Polish tax authorities within one month from the CJEU's decision (by March 27, 2025) or with administrative courts within three months.

• Case-by-Case Assessment: Each situation should be individually evaluated based on specific circumstances and applicable domestic regulations.

Broader Implications

The decision reinforces several key principles that impact investment taxation across the EU:

• While Member States remain free to determine management forms for investment funds established in their territory, they cannot deny tax advantages to non-resident funds solely because they use management structures authorized in their home state.

• Tax provisions that deter non-resident investment funds from investing in a Member State may breach the free movement of capital. 

• The standard for justifying restrictions on fundamental freedoms remains high - proposed justifications must be suitable for achieving their stated objectives.

Taxology's Perspective

This ruling continues the CJEU's trend of breaking down tax barriers within the EU internal market and protecting cross-border investment. It serves as a reminder that Member States must ensure their tax systems do not create unjustified obstacles to the free movement of capital, even when distinctions are not directly based on residence.

Investment funds and their managers should review their structures and potential claims in light of this decision. The ruling may also have implications beyond Poland, as similar provisions in other Member States could now be vulnerable to challenge.
