Transfer Pricing in Tax Audits
Transfer pricing adjustments are the most frequent trigger for bilateral correction coordination DE↔CH: an upward adjustment in one state requires the corresponding correction in the other — and that correction must be actively enforced, not waited for.
The core issue
Germany and Switzerland both apply the arm's length principle, but their methodologies diverge in practice. When a German audit adjusts an intercompany price, the Swiss counterparty does not automatically receive relief — creating a taxable surplus in both states that only coordinated intervention eliminates.
Typical situations
Intercompany price challenged in audit
A German tax audit rejects the transfer price for an intercompany transaction with a Swiss group entity — services, loans, royalties or goods. The proposed adjustment increases the German tax base without a corresponding reduction in Switzerland, generating double taxation on the same economic income.
Corresponding correction not automatic
Art. 9 para. 2 of the Germany–Switzerland DTA provides for a corresponding correction, but it must be actively invoked. The Swiss tax authority will not adjust the Swiss tax base on its own — a formal request and substantiated position are required.
Documentation under scrutiny
Where transfer pricing documentation is challenged as insufficient, the burden of proof shifts and the risk of an estimated adjustment rises sharply. We assess the documentation and prepare the substantive defence before the audit concludes.
Recharacterisation by Swiss tax authorities
Swiss cantonal tax authorities may recharacterise transactions between group entities — for example treating a loan to a group company as simulated and reclassifying it as a hidden capital contribution. This triggers a Swiss-side correction that must be addressed in Germany, without any automatic corresponding adjustment.
Swiss profit allocation under home-country pressure
Groups from Germany, Austria, France, Italy, the Netherlands or Poland that concentrate profit in a Swiss holding, service company or IP structure increasingly face home-country audits that challenge whether the allocation to Switzerland is arm's length. The risk is not just a tax adjustment in the home country — it is the forced reversal of a profit position that the Swiss structure was built to hold. Defending the Swiss allocation requires the same bilateral coordination as any other TP dispute: a position that holds in both states simultaneously.
Substance challenged under BEPS and OECD 2022
Since BEPS Actions 8–10 and the 2022 OECD Guidelines, the alignment of profit with value creation has become the primary test. A Swiss entity that holds IP, a principal structure or a cash pool but lacks decision-making staff and operational substance is increasingly vulnerable to recharacterisation by German, Austrian and other European auditors. The challenge arrives at the Swiss doorstep as a secondary consequence — but must be defended there with equal force.
Beyond the tax file
A transfer pricing dispute is rarely only a tax matter. The same intercompany prices that the tax authority questions are the prices that determine reported profits, management bonuses, covenant ratios and the economic interests of every shareholder who does not control the related-party transactions.
Shareholder rights and minority protection
Transfer pricing is one of the mechanisms through which a majority shareholder can structurally reduce the profits of a company in which minority shareholders hold a stake — by directing business to related parties at above-market prices, or receiving services at below-market rates. The minority shareholder has no visibility into whether the intercompany price is arm's length; they see only the deteriorating profit. Where a German-Swiss structure involves minority interests, a TP finding can reinforce shareholder-protection claims under § 311 AktG or the Swiss Code of Obligations. The head of tax then becomes an actor in a governance discussion that extends well beyond the audit file.
Two accounting systems, opposite objectives
Transfer pricing sits at the intersection of two accounting systems that pull in opposite directions. The legal books — statutory accounts filed with tax authorities — serve compliance: reducing taxable income is a legitimate outcome. The management books serve the opposite purpose: they exist to show where the business actually makes money, to set targets and measure performance against them. Maximising profit is the point.
An intercompany price that shifts profit out of a German operating entity for tax purposes simultaneously reduces that entity's management profit — the figure local management is judged and paid against. Bonuses deteriorate, covenant ratios tighten, segment performance looks weak. The head of tax, defending the same TP structure in an audit, must also explain to the CFO and to operating management why the compliance-optimised price is producing management book numbers nobody is satisfied with. A TP audit does not just open a tax file — it forces both conversations into the same room at the same time.
The economic analysis in TP mandates is led by an economist with interim CFO experience — who understands what intercompany prices do to management books and internal reporting, because he has managed both.
How we work
Assess the situation
We review the audit report and assess whether the primary adjustment is contestable and whether a corresponding correction in the other state is available. The analysis covers the Germany–Switzerland DTA, OECD guidelines and the domestic law of both states.
Challenge the primary adjustment
We help resist the original correction by German or Swiss tax authorities — whether by objection, appeal, court proceedings or mutual agreement procedure.
Enforce secondary and corresponding corrections
We formally claim the corresponding corrections from the competent tax authorities and manage these proceedings for Germany and Switzerland synchronously on both sides.
