On July 3, 2025, Poland’s Ministry of Finance published extensive tax explanations on the so-called beneficial owner (BO) clause in the context of withholding tax (WHT). The concept of the beneficial owner is crucial for cross-border payments like dividends, interest, and royalties because it determines eligibility for tax preferences – reduced WHT rates or exemptions. In other words, only an entity that is the beneficial owner of a given payment can benefit from the protection of double tax treaties or EU directives. This mechanism prevents abuse and tax base erosion via conduit companies or shell entities. The beneficial owner clause is designed to ensure that WHT relief is granted only to legitimately entitled parties and not misused through practices like treaty shopping.
What are the Ministry’s tax explanations?
Tax explanations are official guidelines issued by the Ministry of Finance to clarify how tax law should be applied in practice. They are issued under Article 14a of the Tax Ordinance and provide a form of protection for taxpayers. If a taxpayer (or withholding agent) follows the guidance in an explanation, they receive the protection outlined in Article 14k-14m of the Tax Ordinance – meaning the tax authorities should not penalize or dispute a settlement made in line with these official clarifications. In short, a company that acts according to the Ministry’s explanations gains a “safe harbor,” shielding it from negative tax consequences in case of a later dispute.
Beneficial owner in WHT – definition and criteria
The guidance from July 3, 2025 recalls the definition of a beneficial owner in the CIT Act (Polish Corporate Income Tax law). A beneficial owner is an entity that meets all of the following three conditions:
- receives the payment for its own benefit, i.e. truly and effectively enjoys the income and bears the economic risk of its loss,
- is not obliged to pass on that payment (in whole or in part) to another entity (i.e. is not an intermediary or trustee),
- conducts genuine business activity in its country of residence (with a level of substance appropriate to the nature and scale of the received payment).
The first two criteria essentially boil down to one core concept – having full control and dominion over the income. The term “beneficial owner” refers to an entity that actually and effectively benefits from the payment. If a company is contractually or factually required to forward the received funds to someone else, it cannot be considered the beneficial owner of that income. The requirement of conducting real economic activity complements the above by checking that the entity has economic substance – real resources (personnel, infrastructure, business operations) commensurate with the functions it performs. This is to prevent situations where WHT preferences are claimed by mere letterbox companies without substantive operations.
Importantly, the beneficial owner test is not a general anti-avoidance rule (GAAR) that only the tax authorities can apply. On the contrary – it is a condition that the payer must self-assess before granting a WHT exemption or reduced rate. This principle is reflected in both Polish law and case law. Poland’s Supreme Administrative Court (NSA) has emphasized that the term beneficial owner should be interpreted in light of the purpose of tax laws, not in a narrow technical sense. Likewise, the Court of Justice of the EU has noted that the term “beneficial owner” excludes intermediary companies and should not be read too narrowly – it must be understood in a way that prevents tax abuse.
Due diligence and scope of payments for BO verification
The July 3, 2025 guidance clarifies when a payer must verify the recipient’s beneficial owner status. In general, this requirement applies to the aforementioned “passive payments” – that is, dividends, interest, and royalty payments made abroad. These are the types of income subject to WHT and for which the BO concept is used. For example, if a Polish company pays a dividend to a foreign parent company or interest to an overseas group lender, it must exercise due diligence to determine whether the recipient is the beneficial owner of that income. Only then can the company apply a WHT exemption or reduced rate under domestic law (implementing an EU directive) or under an applicable tax treaty.
The payer should collect appropriate documentation (e.g. the counterparty’s tax residency certificate, representations, analysis of the recipient’s functions) and evaluate whether the recipient fulfills the BO criteria.
Importantly, not every outbound payment is subject to this verification. Payments for services (e.g. consulting, advertising or other intangible services), which are typically treated as business profits under tax treaties, do not require a BO check. In other words, if a payment is not a passive income normally subject to withholding tax, the payer does not have to determine the beneficial owner. The focus on interest, royalties and dividends is due to the fact that these categories are most often prone to abuse (such as creating artificial conduit structures to attain WHT exemptions).
Who should take note?
The new tax explanations are a must-read above all for businesses that make outbound payments subject to withholding tax. This includes, for example:
- Finance departments and tax advisers serving such companies – they should update their due diligence procedures and counterparty vetting processes in line with the clarified BO criteria.
- Polish companies paying dividends, interest or royalties to foreign entities (such as dividends to a foreign shareholder, interest on a loan to an overseas group company).
- International capital groups with holding structures involving Polish companies – they need to ensure that when claiming WHT exemptions under EU directives (e.g. the EU Parent-Subsidiary Directive for dividends), the beneficial owner conditions are satisfied.
Beneficial owner – consult a tax advisor
The beneficial owner concept and the related documentation requirements can be complex and highly dependent on the specifics of each case. The latest Ministry guidance provides many pointers (including practical examples and references to rulings of the NSA and the CJEU), but in case of doubt it is wise to consult a professional tax advisor. An advisor can help determine whether, in a given situation, the foreign payment recipient meets the beneficial owner conditions and whether the available documentation (e.g. agreements, residency certificates, financial statements) is sufficient to support the WHT relief claimed. This way, the payer minimizes the risk of having the tax benefit challenged by the authorities and can avoid potential penalties.
