Background of the Principal Purpose Test
The Principal Purpose Test (PPT) is one of the key anti-abuse mechanisms introduced in modern tax treaties following the OECD Base Erosion and Profit Shifting (BEPS) project. Its purpose is to prevent taxpayers from obtaining treaty benefits through arrangements that lack a genuine economic rationale.
Under the PPT rule, treaty benefits such as reduced withholding tax rates may be denied if it is reasonable to conclude that one of the principal purposes of an arrangement or transaction was to obtain a tax advantage under the treaty, unless granting the benefit is consistent with the object and purpose of the treaty.
The rule was introduced through the OECD Multilateral Convention to Implement Tax Treaty Related Measures to Prevent BEPS (MLI) and has since been incorporated into a large number of bilateral tax treaties worldwide.
As a result, the application of treaty benefits increasingly depends not only on formal conditions such as shareholding thresholds or holding periods, but also on the economic rationale and substance of the corporate structure.

Application of PPT in cross-border corporate structures
In practice, the Principal Purpose Test has significant implications for multinational groups using holding companies in jurisdictions such as the Netherlands or Luxembourg.
Traditional holding structures often rely on a combination of:
However, tax authorities may examine whether a holding company genuinely performs a strategic or economic role within the corporate group. If the entity functions merely as a conduit for routing income between jurisdictions, treaty benefits may be challenged under the PPT.
Factors commonly considered by tax authorities include:
These considerations reflect the broader shift in international tax policy toward evaluating substance and commercial rationale rather than relying solely on formal legal arrangements.
- participation exemption regimes
- reduced withholding tax under double taxation treaties
- EU directives governing intra-EU dividend flows

- whether the holding company exercises real decision-making authority
- the presence of directors and management in the jurisdiction
- the economic purpose of the investment structure
- the functional role of the entity within the corporate group

Interaction with EU anti-avoidance framework
Within the European Union, the application of treaty anti-abuse provisions is closely connected to broader regulatory initiatives designed to prevent aggressive tax planning.
Key elements of this framework include:
Together, these measures reinforce the principle that corporate structures must reflect genuine economic activity in order to benefit from preferential tax treatment under EU law and international tax treaties.
- the EU Anti-Tax Avoidance Directive (ATAD)
- anti-abuse provisions within the EU Parent-Subsidiary Directive
- jurisprudence of the Court of Justice of the European Union (CJEU) concerning beneficial ownership and abuse of rights
Together, these measures reinforce the principle that corporate structures must reflect genuine economic activity in order to benefit from preferential tax treatment under EU law and international tax treaties.
[IMPORTANT!] Practical implications for European holding companies
For multinational groups establishing holding companies in jurisdictions such as Luxembourg or the Netherlands, the introduction of the Principal Purpose Test has significantly changed the landscape of international tax planning.
Modern holding structures are typically designed with a greater emphasis on economic substance, governance and operational functions within the holding jurisdiction. This may include local directors, board meetings, corporate management functions and administrative infrastructure supporting the activities of the holding company.
While treaty networks and participation exemption regimes remain central features of European holding structures, their application increasingly depends on demonstrating that the holding company performs a genuine role within the corporate group and that the structure is supported by legitimate commercial objectives.

Examples of situations where the Principal Purpose Test may deny treaty benefits
In practice, the application of the Principal Purpose Test depends on the specific facts and circumstances of a transaction or corporate structure. Tax authorities typically evaluate whether the structure has a genuine commercial purpose beyond obtaining treaty benefits.
- Conduit holding companiesOne of the most frequently discussed scenarios involves so-called conduit entities. In such structures, a holding company located in a treaty jurisdiction receives income from subsidiaries and quickly transfers that income to another entity in a different jurisdiction.
If the holding company performs no meaningful management, financing or governance functions and merely passes the income onward, tax authorities may conclude that the company acts only as an intermediary.
In these circumstances, treaty benefits may be denied on the basis that the principal purpose of the structure was to obtain a reduced withholding tax rate. - Artificial relocation of holding companiesAnother situation arises when a corporate group relocates a holding company to a jurisdiction primarily to benefit from favourable treaty provisions.
For example, if a newly incorporated holding company in the Netherlands or Luxembourg acquires shares in foreign subsidiaries shortly before a dividend distribution and does not perform ongoing management functions, tax authorities may question whether the entity has a genuine economic role.
Under the Principal Purpose Test, the existence of such timing and structural changes may indicate that obtaining treaty benefits was one of the principal purposes of the arrangement. - Lack of economic substanceStructures where the holding company lacks sufficient economic substance may also be challenged.
Tax authorities often review factors such as:- whether the company has resident directors
- where strategic decisions are taken
- whether the entity maintains a physical office
- whether the company bears economic risk related to the investment
If the holding company cannot demonstrate genuine operational or managerial functions, treaty benefits may be denied even if the legal requirements of the treaty appear to be satisfied. - Circular or artificial financing structuresCertain financing structures may also raise concerns under the Principal Purpose Test. These may include arrangements where funds move through multiple entities within a group without a clear commercial purpose other than obtaining treaty benefits.
In such cases, tax authorities may examine the overall economic effect of the structure and determine whether the transaction reflects genuine financing activity or an artificial arrangement designed primarily to reduce withholding taxes.
Increasing scrutiny by tax authorities
In recent years, tax administrations across Europe have significantly increased scrutiny of cross-border structures relying on treaty benefits. This reflects the broader policy shift following the OECD Base Erosion and Profit Shifting (BEPS) project and the implementation of the Multilateral Instrument (MLI).
As a result, multinational groups increasingly design holding structures that combine treaty access with genuine governance, management and economic functions in the jurisdiction where the holding company is established.
