Transfer Pricing in Liechtenstein

The legal framework

Liechtenstein's transfer pricing statute is short because almost everything of substance is imported. Article 49(1) of the Tax Act (Steuergesetz, LGBl. 2010 No. 340) states the rule: where income or expense from a business relationship with a related person, or between head office and permanent establishment, has been altered by conditions independent third parties would not have accepted in otherwise identical circumstances, taxable net income must be restated to the third-party outcome. Article 49(2) adds a duty to prove appropriateness by documentation; Article 49(3) delegates the detail to the Government.

The delegated instrument does the heavy lifting. Article 31b(1) of the Tax Ordinance (LGBl. 2010 No. 437) requires dealings with related persons and permanent establishments to be priced under the OECD Transfer Pricing Guidelines in their current version. The reference is ambulatory, so revisions land in Liechtenstein law without a domestic amendment — which is why the jurisdiction reports no domestic rules on intangibles, hard-to-value intangibles, intra-group services or cost contribution arrangements while still producing OECD-compliant outcomes.

Who counts as related is deliberately wide. Article 31a reaches participants in the taxpayer, entities the taxpayer participates in or benefits, governing bodies, and persons in a close personal relationship — family or friendship — plus anyone close to those persons. There is no percentage test in the definition; the 25% figure appears only later, as a filter on the documentation duty. The rule applies to legal persons taxed at 12.5% (minimum CHF 1,800) and, via Article 16(6), the self-employed, and reaches domestic dealings as readily as cross-border ones.

Methods, comparables and benchmarking

Article 31b(1)(a) to (f) lists the five OECD methods — comparable uncontrolled price, resale price, cost plus, transactional net margin and transactional profit split — and admits any other method where none of them properly reflects an arm's length result. Selection is by most appropriate method on the transaction's actual facts: no hierarchy, no domestic tie-breaker, and in practice no use of the residual category.

Benchmarking is where the thin-statute design is felt. Liechtenstein publishes nothing on comparable searches, tested-party selection or statistical narrowing. Chapter III of the Guidelines applies directly by operation of Article 31b(1), so a search performed to OECD standards is a search performed to Liechtenstein standards. The Fiscal Authority expresses no preference for domestic comparables — sensibly, since no Liechtenstein database exists — and does not use secret comparables. Ranges are accepted, with interquartile-type narrowing applied as practice rather than rule.

Intra-group financing is the one place where an administrative number replaces a comparables search. The Tax Administration's annual Merkblatt on interest rates for benefits in kind fixes safe harbour rates for related-party balances. For 2026 the Swiss franc minimum on receivables is 1.25% where equity-financed (1.50% for 2025, 2.00% for 2024), or cost of funds plus 0.50% subject to that floor where debt-financed; the Swiss franc maximum on payables is 1.25%. Foreign currency rates for 2026 include 3.25% on the euro, 4.50% on the dollar and sterling, 7.75% on the rand. These are a safe haven, not a bar to argument: a different rate may be substantiated by study. Undercharge a receivable and income is imputed; overcharge a payable and the deduction is cut.

Documentation: what the Fiscal Authority expects

Article 31b, unamended since LGBl. 2017 No. 442 introduced it for tax year 2018, tiers the burden by group size rather than by transaction alone. A taxpayer in a group with consolidated turnover above CHF 900 million must hold a master file and local file to OECD specification, covering cross-border transactions where goods purchases or sales exceed CHF 1,000,000 per counterparty per year, or other income and expense exceeds CHF 250,000 per category per counterparty per year. A taxpayer that is not part of such a group — which includes a member of a smaller group, not only a company with no group at all — owes a lighter five-part file if it exceeds all three medium-company criteria in Article 1064(2) PGR: CHF 32.4 million balance sheet total, CHF 64.8 million net turnover, 250 average employees, as raised by LGBl. 2024 No. 170. That file covers business model and structure; a list of all related-party and permanent establishment relationships; the allocation of functions, risks and assets; method selection with reasons; and the analysis supporting the prices charged. Its transaction thresholds are half the larger tier's, at CHF 500,000 and CHF 125,000. Sources quoting CHF 51.8 million here rely on superseded PGR values.

Both tiers reach Article 31a(a) and (c) related persons only where participation or beneficial entitlement is at least 25%. Below the thresholds nothing disappears: Article 31b(8) requires arm's length compliance to be proved on request with suitable supporting documents, so there is no de minimis exemption, only a lighter evidential burden.

There is no annual filing deadline and no transfer pricing schedule in the return. Documentation is produced on request within 60 days, in German or English, with no statutory extension — which makes contemporaneous preparation the only workable posture. The routine disclosure is instead the Article 41(2) duty, in the electronically filed return, to attach account statements for loans and current accounts with beneficial owners and related persons. Country-by-country reporting sits separately under the CbC Act (LGBl. 2016 No. 502): groups above CHF 900 million — not EUR 750 million — file within 12 months of year end, in the OECD XML schema through the form server, having registered with the International Division by the last day of the first reporting period.

Audits, penalties and the enforcement climate

There is no bespoke documentation penalty. Failure to produce within 60 days is an administrative offence under Article 135 of the Tax Act, punishable after a reminder by a fine of up to CHF 1,000, rising to CHF 10,000 in serious or repeated cases; the flat CHF 10,000 in the OECD profile is the ceiling, not the norm. Real exposure lies elsewhere. Where an adjustment reflects an incomplete or incorrect return, Article 137 treats it as evasion, fined as a rule at one times the tax evaded, cut to a third for slight fault and trebled for serious fault; untrue books make it fraud under Article 140, carrying up to six months' imprisonment. Country-by-country breaches are the outlier — up to CHF 250,000 intentionally, CHF 100,000 negligently, CHF 500,000 for serious, repeated or systematic failures.

Two procedural levers matter more than the tariffs. Where records are unreliable or incomplete, Article 102(2) permits assessment at the authority's discretion and Article 116(3) confines an objection to manifest incorrectness, so a thin file moves the fight onto ground taxpayers usually lose. Against that, Article 142 gives full penalty relief on a genuine first voluntary disclosure, with only back tax due. Assessment lapses after five years subject to a ten-year longstop, interrupted by any authority act aimed at establishing the liability.

Enforcement patterns show up in case law, not statistics: none are published. Around twenty judgments turn on the Fremdvergleichsgrundsatz, overwhelmingly Administrative Court decisions from 2015 to 2025 on related-party financing and hidden profit distributions.

Dispute resolution and advance certainty

Liechtenstein has no APA statute. What it has is Article 93a of the Tax Act: binding advance information on a precisely described set of facts not yet realised, and binding assurance after audit of a realised fact pattern. Article 38a of the Ordinance sets the application content — applicant identity, a comprehensive statement of facts, concrete legal questions and the applicant's analysis — and a fee is charged. The ruling binds unless the facts later deviate materially, and can be revoked prospectively if found incorrect. That is the working unilateral APA. Bilateral arrangements run through the International Division under the mutual agreement article of the relevant treaty; no fee, term or rollback policy is published, and any source describing a formal Liechtenstein APA programme deserves scepticism.

MAP is better documented. Requests go in writing, in German or English, to the International Division at Aeulestrasse 38, Vaduz (dba@llv.li), within three years of the first notification of the taxing action, irrespective of domestic remedies; protective requests are recognised. Fourteen treaties carry arbitration clauses, including Germany, Switzerland and the United Kingdom. Agreements are implemented regardless of domestic time limits, except under the Swiss treaty where Article 124 applies: 90 days from the agreement, ten years from the assessment.

Since 2025 a unilateral route exists too. The rewritten Article 63 allows a Liechtenstein downward adjustment to match a foreign correction with no treaty in play, and to match a domestic upward correction at a related Liechtenstein taxpayer — on proof that the original price was defensible under Article 49, that the foreign correction is itself arm's length, and that it was properly contested abroad. Article 36d imposes a three-month application deadline. Ordinary appeals run from a 30-day objection to the National Tax Commission, the Administrative Court and the Constitutional Court.

Pillar Two and what changes in 2026

The global minimum tax has applied since 1 January 2024 under the GloBE Act (LGBl. 2023 No. 484), covering domestic constituent entities of groups whose ultimate parent reported at least EUR 750 million of consolidated revenue in two of the four preceding years. The 15% floor is collected through a qualified domestic minimum top-up tax and an income inclusion rule. Returns fall due 15 months after year end, 18 on first application; the 2024 due date was 30 June 2026, payable in Swiss francs within 30 days, and 2024 GloBE Information Returns fell due the same day. The trap is the currency: EUR 750 million for Pillar Two, CHF 900 million for both country-by-country reporting and the master file trigger.

On Pillar One Amount B, Liechtenstein has published nothing — no ordinance, no guidance, no newsletter item across the 2018 to 2026 index. Because Article 31b(1) incorporates the Guidelines as they stand, Amount B would enter Liechtenstein practice through that door if adopted into them, with no domestic instrument. Meanwhile the Constitutional Court's December 2025 pair, StGH 2025/114 and 2025/115, confirms that the authority will pursue eight-figure related-party add-backs and that the courts will uphold them.

How practitioners should respond

Three conclusions follow. Treat the OECD Guidelines as the operative Liechtenstein text and Article 31b(1) as the only bridge required — but confirm which edition was current when the transaction was priced, because the reference moves. Build the file before the request arrives: sixty days with no extension mechanism, against a discretionary assessment power that reverses the practical burden of proof, is no window in which to commission a benchmarking study. And price intra-group balances against the annual interest Merkblatt by default, departing from it only on a study capable of surviving the financing line the courts have developed since 2015. The recurring loss is the interest-free or under-priced receivable, and the asymmetry in StGH 2018/042 still holds: receivables carry a minimum rate, payables a maximum, and no taxpayer imputes a larger deduction on the payable side.

Two verification habits help. The Tax Administration restructured its website in 2026, so older links fail and live pages sit behind bot protection returning 403 to scripted clients; check citations in a browser. And judgments have no stable URLs: cite by court and docket number.
