Liechtenstein tax law 2025 entered its final quarter with several notable legislative and administrative developments that directly affect international businesses, private wealth structures, and domestic enterprises operating in the principality. The period brought refinements to corporate income tax rules, updated guidance on substance requirements, and continued alignment with OECD global minimum tax standards. This guide summarises the key changes, explains their practical implications, and identifies the steps businesses should consider in response.
The most consequential development of the quarter was the formal adoption of amendments to the Tax Act (Steuergesetz, SteG), which governs corporate income tax, wealth tax, and coupon tax in Liechtenstein. The amendments clarified the treatment of intra-group financing arrangements, tightening the conditions under which interest deductions are permitted on related-party loans. Specifically, the revised provisions require that loan terms demonstrably reflect arm';s-length conditions, supported by contemporaneous documentation. Entities that relied on informal or undocumented intercompany lending arrangements should treat this as a priority compliance matter.
A second legislative change addressed the taxation of collective investment vehicles. The amendment introduced a clearer distinction between regulated investment undertakings that qualify for the existing exemption regime and those that do not, based on the nature of their investor base and the regulatory authorisation they hold. Structures that previously operated in a grey area now face a binary classification: either they satisfy the conditions for the investment undertaking exemption under the SteG, or they are treated as ordinary taxable entities. Advisers working with fund structures should review classifications promptly.
The Liechtenstein parliament (Landtag) also passed a technical amendment to the Coupon Tax Act (Couponsteuergesetz), adjusting the scope of instruments subject to the 4% coupon tax. The change narrows the definition of taxable instruments in line with modern financial product structures, removing certain hybrid instruments from the scope of the tax where their economic substance more closely resembles equity than debt. This is a welcome clarification for structured finance practitioners.
Liechtenstein has been advancing its domestic implementation of the OECD Pillar Two global minimum tax framework, which targets large multinational enterprise groups with consolidated revenues above a defined threshold. During the quarter, the government published updated administrative guidance on the Qualified Domestic Minimum Top-up Tax (QDMTT), which Liechtenstein introduced to ensure that top-up tax on low-taxed profits is collected domestically rather than by a parent jurisdiction abroad.
The guidance addressed several practical questions that had remained open since the initial legislation. It clarified how the substance-based income exclusion - which carves out a return on payroll costs and tangible assets from the top-up tax base - is to be calculated for entities with mixed activities. It also confirmed that the transition-year safe harbour rules apply to Liechtenstein-based constituent entities of in-scope groups, provided that the group';s country-by-country reporting data meets the required quality standards.
For businesses, the practical implication is straightforward: groups with a Liechtenstein holding, finance, or operating entity need to assess whether they fall within the scope of the QDMTT and, if so, whether the substance-based exclusion meaningfully reduces their exposure. Many holding structures that were established primarily for tax efficiency rather than operational substance may find that the exclusion provides limited relief. In practice, founders should consider whether the economic substance of their Liechtenstein entities - measured in terms of qualified employees and tangible assets - is sufficient to support the exclusion calculation.
A common mistake among international groups is to assume that Liechtenstein';s historically low effective tax rate automatically places them outside Pillar Two concerns. The QDMTT mechanism means that even where the domestic rate is low, a top-up charge may apply if the effective rate on a jurisdictional basis falls below the global minimum. Groups should model their effective tax rate position under the Pillar Two rules before the next filing period.
The Financial Market Authority (FMA) and the Tax Administration (Steuerverwaltung) continued their coordinated approach to substance requirements during the quarter. Liechtenstein';s substance framework, which applies to holding companies, intellectual property holding structures, and finance entities, requires that entities demonstrate genuine economic activity in the principality. This includes having qualified management present in Liechtenstein, holding board meetings locally with substantive decision-making, and maintaining adequate local infrastructure.
Recent administrative practice has reinforced that the Steuerverwaltung will scrutinise structures where the majority of strategic decisions are demonstrably made outside Liechtenstein, even if the entity is formally registered and administered there. A non-obvious requirement that frequently catches foreign founders off guard is the expectation that board resolutions reflect genuine deliberation rather than rubber-stamping decisions already made at the group level. Minutes that are too brief or formulaic have been flagged in recent reviews.
For intellectual property structures in particular, the guidance issued during the quarter reiterated that the nexus approach applies: the proportion of IP income that qualifies for preferential treatment is linked to the proportion of qualifying research and development expenditure incurred by the entity itself, rather than by related parties. Groups that outsource R&D to affiliates and then hold the resulting IP in Liechtenstein should carefully assess whether their nexus ratio supports the tax treatment they have applied.
The quarter also saw the FMA issue updated guidance on the registration and ongoing compliance obligations of private asset structures (Privatvermögensstrukturen, PVS). The PVS regime, which provides a favourable tax treatment for structures holding private assets, requires that the structure does not engage in commercial activity and that its assets are genuinely private in nature. The updated guidance clarified what constitutes commercial activity for this purpose, with specific reference to the holding of operating company shares and the provision of services to third parties.

Transfer pricing remained a focus area for the Steuerverwaltung during the quarter. Liechtenstein applies the OECD Transfer Pricing Guidelines as the primary interpretive framework for related-party transactions, and the quarter brought updated administrative guidance confirming that the arm';s-length principle applies to all material transactions between associated enterprises, including the provision of services, the use of intellectual property, and financial transactions.
The guidance placed particular emphasis on financial transactions, reflecting the OECD';s own updated guidance in this area. Intra-group loans must be priced to reflect the borrower';s credit quality on a standalone basis, taking into account the implicit support that group membership may provide but not treating that support as a substitute for arm';s-length pricing. Cash pooling arrangements, which are common in multinational groups with Liechtenstein treasury entities, must be documented to show that the pricing of pool participation reflects the economic contribution of each participant.
Documentation requirements were also clarified. Entities that are part of groups above the threshold for country-by-country reporting must maintain a master file and a local file in accordance with the OECD three-tier documentation standard. The Steuerverwaltung confirmed that it expects documentation to be prepared contemporaneously - that is, before the filing of the tax return for the relevant period - rather than reconstructed after the fact in response to an enquiry.
Many underestimate the resource commitment involved in preparing compliant transfer pricing documentation for Liechtenstein entities. The local file must contain a detailed functional analysis of the entity';s activities, risks, and assets, as well as a benchmarking study supporting the pricing of each material transaction category. Entities that have not yet established a documentation process should treat this as an urgent priority.
A practical scenario illustrates the risk: a European group with a Liechtenstein finance entity that on-lends funds to operating subsidiaries across the group may find that its existing loan pricing, based on a group credit rating rather than a standalone assessment, does not satisfy the current guidance. A transfer pricing review and potential repricing of the loans may be required before the next tax return is filed.
The Steuerverwaltung';s approach to advance tax rulings continued to evolve during the quarter. Liechtenstein';s ruling practice allows taxpayers to obtain binding confirmation of the tax treatment of a proposed transaction or structure before implementation. The quarter saw the Steuerverwaltung refine its internal procedures for processing ruling requests, with a focus on ensuring that rulings are granted only where the facts presented are sufficiently specific and the legal question is genuinely uncertain.
In practice, this means that ruling requests framed at a high level of generality - for example, seeking confirmation that a holding structure is "tax efficient" without specifying the transactions involved - are less likely to receive a substantive response. Requests that present a detailed factual matrix and identify the specific legal provisions in question are processed more efficiently. Advisers should structure ruling requests accordingly.
On the enforcement side, the Steuerverwaltung signalled an increased focus on the consistency between the facts presented in ruling requests and the actual implementation of structures. Where a ruling has been obtained on the basis of a particular set of facts, and the structure is subsequently implemented in a materially different way, the ruling does not provide protection. This is a de jure position that has always applied, but the quarter brought a clearer administrative statement of intent to verify implementation.
A second practical scenario: a family office that obtained a ruling several years ago confirming the PVS status of its Liechtenstein structure may find that subsequent changes to the asset base - for example, the acquisition of shares in an operating company - have altered the factual basis of the ruling. A review of whether the current facts still support the ruling';s conclusions is advisable.
The appeals process before the Administrative Court (Verwaltungsgericht) and, ultimately, the Administrative Court of Appeal (Verwaltungsgerichtshof) remained available to taxpayers disputing assessments. The quarter did not produce landmark court decisions that materially altered the interpretation of the SteG, but several procedural decisions reinforced the importance of engaging with the Steuerverwaltung at the objection stage before proceeding to court. Costs and timelines at the court level are significant, and early resolution through the administrative process is generally preferable.

Does the QDMTT apply to all companies registered in Liechtenstein?
The Qualified Domestic Minimum Top-up Tax applies only to constituent entities of multinational enterprise groups whose consolidated annual revenues exceed the threshold set by the Pillar Two framework. Purely domestic businesses and smaller international groups below the threshold are not within scope. However, groups that are close to the threshold should monitor their position carefully, as the rules apply on a group-wide basis and a single year of exceeding the threshold can bring the entire group into scope. Liechtenstein entities that are part of in-scope groups should assess their effective tax rate position and the availability of the substance-based income exclusion before the relevant filing deadline.
How long does it take to obtain an advance tax ruling in Liechtenstein, and what does it cost?
The timeline for obtaining an advance tax ruling from the Steuerverwaltung varies depending on the complexity of the request and the current workload of the authority. Straightforward requests involving well-established legal principles may be resolved within a few weeks, while complex or novel questions can take several months. There is no fixed statutory fee for rulings, but professional fees for preparing a well-structured ruling request - including the factual matrix, legal analysis, and supporting documentation - typically represent a meaningful investment. Engaging experienced local counsel to prepare the request reduces the risk of delays caused by requests for additional information.
What are the main risks for a Liechtenstein holding company that does not meet substance requirements?
A Liechtenstein holding company that fails to demonstrate genuine economic substance faces several risks. The Steuerverwaltung may challenge the tax treatment applied to income received by the entity, potentially reclassifying it or denying the benefit of applicable exemptions. Foreign tax authorities in the jurisdictions where the group';s operating entities are located may also challenge the holding company';s residence or the arm';s-length nature of transactions with it, particularly where the holding company is seen as lacking genuine decision-making capacity. In addition, the absence of substance may affect the availability of treaty benefits under Liechtenstein';s network of double tax agreements. Addressing substance deficiencies proactively - through the appointment of qualified local directors, the holding of genuine board meetings in Liechtenstein, and the maintenance of adequate local infrastructure - is significantly less costly than managing a challenge after the fact.
The final quarter brought meaningful developments across corporate income tax, the global minimum tax framework, substance requirements, transfer pricing, and administrative practice in Liechtenstein. Businesses with structures in the principality should review their positions against the updated legislative and administrative guidance, prioritising transfer pricing documentation, substance assessments, and QDMTT exposure analysis. Early engagement with the Steuerverwaltung through the ruling process remains a valuable tool for managing uncertainty.
