Economic Substance in Switzerland: Bank and Tax Authority Requirements in 2026

Economic substance in Switzerland: today’s working definition

Economic substance refers to the combination of material, human and functional elements demonstrating that a company carries out a real activity from the State where it is incorporated. In Switzerland, this concept covers four dimensions jointly assessed by banks, the Swiss Federal Tax Administration (FTA) and compliance departments: human presence, functional coherence within the group, balance-sheet solidity and the actual location of decisions.

For a long time, many international structures could operate in Switzerland with a simple address and minimal real presence. This approach is now largely obsolete, particularly when opening bank accounts, during compliance reviews and when tax authorities assess double tax treaty benefits.

In practice, the central question is no longer whether a company exists legally in Switzerland, but whether it possesses genuine substance: effective management, credible governance, minimal operational presence and the real ability to make decisions from Swiss soil.

Tax residency vs. economic substance

A company can be tax-resident in Switzerland while still being perceived as artificial by a bank or an administration. These are two distinct concepts that should never be confused.

A company can be registered in the commercial register, hold a tax number, file annual accounts and be subject to corporate income tax, while still showing a substance profile considered insufficient. Conversely, some relatively simple structures pass controls easily because their operating logic is immediately clear.

Swiss banks: the first operational filter

In most international files, the first difficulties now appear at the bank level, before any tax intervention. Swiss banks seek to understand the overall coherence of the project before accepting an account opening, and KYC/AML reviews are sometimes more demanding than the tax analysis itself.

Concrete questions asked during bank onboarding

Discussions quickly focus on very operational elements:

• Who actually runs the daily activity?
• Where are the teams and offices located?
• Where do the incoming financial flows come from?
• Who are the clients, and how are contracts negotiated?
• Why is the company established in Switzerland rather than elsewhere?

Some structures that look perfectly fine on paper become almost impossible to bank: holding companies without clear operational logic, international commission entities, trading vehicles claiming to manage large flows without economic presence. A simple letterbox with CHF 100,000 share capital no longer impresses anyone in 2026.

Conversely, a modest company with an understandable activity, a few real employees and an involved director is usually accepted quickly because the file looks immediately coherent. Two legally similar files can receive very different bank treatments simply because one project appears credible and the other artificial.

Treaty shopping, rule shopping and substance requirements

Economic substance is directly linked to the concepts of treaty shopping and rule shopping, framed in Switzerland by FTA practice and by OECD standards from the BEPS (Base Erosion and Profit Shifting) project.

Treaty shopping

Treaty shopping consists of artificially interposing a company in a State to benefit from a more favourable tax treaty, typically to reduce withholding taxes on dividends, interest or royalties. Article 7 of the BEPS Multilateral Instrument (MLI), ratified by Switzerland, introduces a Principal Purpose Test (PPT) allowing treaty benefits to be denied when obtaining those benefits is one of the principal purposes of the arrangement.

Rule shopping

Rule shopping is broader: it consists of selecting a jurisdiction for its overall environment (stability, tax regime, legal certainty, international reputation, quality of the banking system). Choosing Switzerland for these reasons is entirely legitimate. The issue arises when the structure has almost no economic reality in proportion to the advantages sought.

The four pillars of credible economic substance

Solid economic substance rests on four complementary dimensions, jointly assessed by banks and tax administration.

Personnel substance: human presence remains fundamental

A company claiming to manage significant international operations without any identifiable employee immediately raises questions. This does not mean hiring dozens of people: banks and authorities seek to understand whether the company has a minimum operational capacity consistent with the activity announced.

Some situations are paradoxical: a SaaS company with a fully remote team may be considered credible despite light infrastructure, whereas an international trading company without physical presence will immediately raise doubts. The most frequent questions are simple: who answers emails, where are the teams, who negotiates contracts, where are day-to-day decisions actually taken.

Functional substance: why “empty” holding companies become fragile

Functional substance concerns the organisational coherence of the group. An international holding with several substantial participations in different countries naturally looks more credible than a simple intermediary company used only to receive dividends.

Some structures become fragile when they hold a single asset and have no activity of their own. The implicit question from banks and authorities is then: why does this company really exist?

Balance-sheet substance: the issue of undercapitalised companies

Balance-sheet substance is probably one of the most observed criteria in modern bank analysis. A company must have a level of equity coherent with its activity. Practice frequently refers to a self-financing ratio of around 30%, calculated as equity divided by total balance sheet, multiplied by 100.

This threshold is not a legal rule, and some banks weigh it more than others depending on sector. A heavily undercapitalised company will however often be perceived as artificially financed. Conversely, some operational companies run naturally with low equity but have real clients, real activity and a real team: this overall coherence is what matters.

Decisional substance: where are decisions made?

Decisional substance concerns the effective location of strategic and operational decisions. A company whose board meetings take place abroad, whose minutes are signed elsewhere and whose director does not reside in Switzerland presents an immediate risk of tax requalification (concept of effective place of management under article 50 DBG/LIFD).

This is precisely why the role of the Swiss resident director has become central in modern international structures.

The shield effect of operational companies

A company with a genuine commercial activity naturally benefits from additional credibility in bank and tax analysis. In practice, an industrial, technological or commercial company with employees, clients, contracts and an identifiable activity will be much easier to defend than a simple passive holding.

The underlying trend is clear: it is no longer purely legal structures that reassure, but economically coherent ones. FTA practice recognises a “shield” effect for operational companies, which benefit from a much stronger substance presumption than pure holding vehicles.

The role of the Swiss resident director

The Swiss resident director plays a pivotal role in demonstrating substance. The function goes well beyond the legal obligation in article 718(4) of the Swiss Code of Obligations (at least one board member domiciled in Switzerland and able to represent the company). In modern practice, the resident director embodies the decisional substance expected by banks and the FTA.

My Swiss Company SA, a Swiss Corporate Services Provider with offices in Geneva, Lucerne and Zug, supports international companies from over 20 countries. Our role as resident director or manager is part of a comprehensive approach: documented governance, minutes signed on Swiss soil, follow-up on strategic decisions and coordination with the foreign organs of the group. This approach is illustrated in our case studies.

Shell company, letterbox entity, sociedad pantalla: same risk, different name

“Shell company”, “letterbox entity”, “société écran” or “sociedad pantalla”: these designations from different markets cover the same operational concept — a company without real economic substance. In a global economy where Swiss banks review files from French-, English- and Spanish-speaking entrepreneurs, mastering this terminology has become important to anticipate compliance questions.

Swiss tax authorities and the FTA mainly use the formulation “company without substance”. Anglo-Saxon regulators (FATF, OECD) refer to “shell entity” or “letterbox company”. Hispanic jurisdictions (notably Spain, Mexico, Colombia) use “sociedad pantalla”. The test remains identical everywhere: effective management, real activity, coherent equity, human presence, decision traceability.

This international convergence of the substance standard explains why an entrepreneur based in Madrid, Geneva or Singapore will face exactly the same questions before a modern Swiss bank. The vocabulary changes; the criterion does not.

FAQ: Economic substance in Switzerland

What is the economic substance of a Swiss company?

Economic substance refers to the concrete elements demonstrating that a company conducts real activity from Switzerland: human presence (employees, premises), coherent economic function within the group, equity suited to the activity, and effective location of decisions on Swiss soil. It is jointly assessed by banks, the Swiss Federal Tax Administration and compliance departments, independently of formal tax residency.

What is the difference between tax residency and economic substance?

Tax residency rests on legal criteria (registered seat or place of effective management under art. 50 DBG/LIFD) and determines where the company is taxed. Economic substance is a multi-criteria factual analysis that conditions access to banking services, treaty benefits and credibility before foreign partners. A company can be tax-resident in Switzerland while presenting insufficient economic substance.

What equity ratio is expected for a credible Swiss company?

Swiss banking practice considers that an equity ratio of around 30% of total balance sheet is a reasonable benchmark for a standard international company. A company with a ratio below 10% will frequently be perceived as artificially financed. This threshold is not an absolute legal rule and varies by sector, but it remains a decisive indicator in KYC/AML analysis.

Can a holding company without employees still have economic substance?

A pure holding can retain sufficient substance if it holds several active participations, performs a genuine international coordination role and has resident management in Switzerland signing strategic decisions on Swiss soil. Conversely, a holding holding a single passive asset, without localised governance and without activity of its own, becomes particularly fragile against modern bank and tax controls.

Why have Swiss banks become so demanding on substance?

KYC/AML obligations imposed by the Swiss Anti-Money Laundering Act (AMLA), combined with OECD/BEPS standards and the Principal Purpose Test introduced by the BEPS Multilateral Instrument, expose banks to major compliance risks in case of opaque files. A structure whose economic logic is not immediately clear represents a reputational and regulatory risk that Swiss institutions now refuse to bear, regardless of capital or legal quality of the file.

How to strengthen the economic substance of an existing Swiss company?

Several concrete levers exist: appointment of a Swiss resident director performing an effective role, documented board meetings in Switzerland, allocation of employees or providers located on Swiss soil, alignment of the equity ratio with banking standards, contractual documentation of real commercial activity and formalisation of a synthetic substance file. Support from a Swiss Corporate Services Provider with offices in Geneva, Lucerne and Zug helps to structure these elements coherently.

Is treaty shopping prohibited in Switzerland?

Treaty shopping as such is not formally prohibited, but it is largely neutralised since the entry into force of the BEPS Multilateral Instrument ratified by Switzerland. The Principal Purpose Test (art. 7 MLI) allows the FTA and foreign authorities to deny treaty benefits when obtaining them is one of the principal purposes of the arrangement. Economic substance remains the decisive criterion: a Swiss company with real substance keeps treaty access even if the structure incidentally provides a tax advantage.
