A Western European holding group acquired a controlling stake in a Polish technology business. The transaction closed quickly. The tax structure, however, had not been reviewed before signing. Within months, the group faced an avoidable withholding tax exposure on dividend repatriations – one that a properly sequenced structure would have mitigated. The cost of that oversight was material.
This case study examines how Ferraz & Whitmore assisted a cross-border investor in restructuring its inbound investment into Poland to achieve corporate income tax efficiency and reduce withholding tax leakage. The engagement involved a review of tax residency considerations, permanent establishment risk, and applicable tax treaty positions. Structural changes were implemented over a period of approximately four months.
The following sections describe the client profile, the strategy applied, key milestones, complications encountered, and three transferable lessons for investors entering the Polish market.
Client profile and the structural challenge
The client was a mid-market private equity vehicle incorporated in a Western European jurisdiction. It had recently completed an acquisition of a Polish operating company active in software development and SaaS distribution.
The client's existing corporate structure had not been designed with Poland's tax legislation in mind. Dividends flowing from the Polish subsidiary to the holding entity were subject to withholding tax at a rate that the applicable tax treaty could have reduced. but only if specific beneficial ownership and substance conditions were satisfied. Those conditions had not been assessed before the deal closed.
A secondary concern was permanent establishment risk. Senior managers of the holding group were conducting operational oversight from their home jurisdiction. Under Polish tax legislation, certain management activities exercised over a Polish entity can, in defined circumstances, give rise to a taxable presence in Poland for the foreign parent. This risk had gone unaddressed.
The client's in-house team recognised the exposure only after receiving initial Polish tax correspondence. By that point, dividend distributions had already been made without applying treaty-reduced withholding tax rates. The group needed a structured response – and a forward-looking solution.
Legal strategy: sequencing substance before distribution
The strategy had two phases. The first addressed the historical exposure. The second redesigned the holding and management structure to support treaty access going forward.
On the historical side, the team conducted a detailed review of whether treaty benefits could be claimed retrospectively. Under the relevant tax treaty, the key condition was beneficial ownership of the income. The holding entity did satisfy that test on the facts. A reclaim procedure was initiated through Poland's tax administration. This required documentary evidence of the holding entity's tax residency, its corporate structure, and the absence of conduit arrangements.
For the forward-looking structure, the focus shifted to substance. Polish tax legislation – consistent with EU anti-avoidance measures – requires that entities invoking treaty benefits demonstrate genuine economic activity. A holding company that exists solely on paper does not qualify. The team advised the client to document management functions, board meeting locations, and decision-making authority within the holding entity. This was not a structural overhaul. It was a documentation and governance exercise that activated treaty protection the entity was already entitled to claim.
Permanent establishment risk was addressed by formalising the boundary between oversight and management. Board-level oversight does not, in itself, create a permanent establishment. Operational management does. Written protocols were introduced to record the scope of activities performed by group executives when dealing with the Polish subsidiary.

Key milestones and complications
The engagement proceeded in four stages over approximately four months.
In the first month, the team completed a tax position review. This covered the withholding tax exposure on prior distributions, the treaty eligibility analysis, and a preliminary assessment of permanent establishment risk. The review identified three distinct areas requiring action.
In month two, the reclaim documentation package was prepared and submitted to the relevant Polish tax authority. The package included a certificate of tax residency from the holding entity's home jurisdiction, a beneficial ownership declaration, and a corporate structure diagram. Polish tax administration procedures allow for reclaims of this type, but the evidentiary standard is high. Incomplete submissions are frequently rejected on procedural grounds without a substantive review.
The primary complication arose here. The holding entity's certificate of tax residency had lapsed. Its home jurisdiction issued renewals only at specific intervals. A gap of several weeks emerged between the submission deadline and the date on which a renewed certificate could be obtained. The team negotiated an extension with the Polish authority and submitted a bridging declaration in the interim. The extension was granted, and the renewed certificate was filed within the agreed period.
In month three, the governance documentation was finalised. Board resolutions, meeting minutes, and management protocols were updated to reflect the substance requirements under Polish tax legislation and the relevant EU directives on anti-avoidance.
By month four, the restructured position was in place. The reclaim remained pending with the Polish tax authority – such procedures typically take between three and nine months to resolve – but the forward-looking structure was operating correctly.

Transferable lessons for cross-border investors
Three lessons from this matter are directly applicable to other inbound investment structures in Poland.
Lesson 1: Treaty access must be verified before the first distribution, not after. Tax treaty benefits on dividends, interest, and royalties are not automatic. They depend on meeting conditions – beneficial ownership, substance, and the absence of artificial arrangements – that must be documented proactively. Waiting until a distribution has been made without applying the reduced rate creates a reclaim procedure that is both time-consuming and uncertain.
Lesson 2: Substance is a governance question, not only a structural one. Many investors assume that treaty access requires reorganising the corporate structure. In practice, the holding entity in this matter was correctly positioned. What was missing was evidence. Board minutes, written management protocols, and documented decision-making authority are the instruments that convert a theoretically eligible structure into a demonstrably compliant one. Under Poland's corporate income tax rules and EU anti-avoidance measures, tax authorities increasingly scrutinise the substance behind treaty claims.
Lesson 3: Permanent establishment risk grows with operational involvement. A foreign parent that supervises strategy does not typically create a permanent establishment in Poland. A foreign parent whose executives make day-to-day operational decisions may. The distinction is rarely clear on the facts. Documenting the boundary between oversight and management – and maintaining that boundary in practice – is a continuous obligation, not a one-time exercise.
