Scenario 02 · Germany → SwitzerlandGerman Companies Investing in Switzerland
A German GmbH or AG can establish or acquire a Swiss AG or GmbH, invest in a Swiss partnership or operate directly through a Swiss permanent establishment. The chosen structure is decisive for German taxation: income from shareholdings, permanent establishment profits, Swiss withholding tax, section 8b KStG, controlled foreign company taxation, transfer pricing and German filing obligations are each governed by different rules.
Starting Point
Investing in Switzerland does not end the German tax analysis
If the investing company remains resident in Germany, it continues to be subject to German corporate income tax and generally also to trade tax. The Swiss investment must therefore be incorporated into the German calculation of taxable profit and tax filings.
The German treatment depends crucially on whether the German company holds shares in a separate Swiss corporation, becomes a partner in a business partnership or operates through its own Swiss permanent establishment.
These three structures differ in their treatment of ongoing profits, distributions, disposals, accounting and application of the tax treaty.

Structure Comparison
Swiss subsidiary, partnership or permanent establishment?
From a German perspective, the legal and tax distinctions between the different investment structures are essential.
| Structure | Basic tax structure | German treatment | Key issues |
|---|---|---|---|
| Swiss AG / GmbH | Separate Swiss taxpayer | Shareholding held as a business asset of the German company | Section 8b KStG, dividends, Swiss withholding tax, AStG and exit |
| Swiss partnership | Classification requires a separate review from a German perspective | If tax-transparent, income is allocated to the German partner on an ongoing basis | Entity classification, tax treaty and permanent establishment income |
| Swiss permanent establishment | Legally part of the German enterprise | Profits remain profits of the German enterprise; treaty allocation is required | Profit attribution, exemption, trade tax and documentation |
| Swiss registered branch | Legally part of the German company | Generally analysed as a permanent establishment for tax purposes | Swiss registration and German permanent establishment treatment |
Swiss AG or GmbH
A German parent company with a Swiss subsidiary
Where a German GmbH or AG holds shares in a Swiss corporation, the parent and subsidiary generally remain two separate taxpayers.
The Swiss company’s ongoing operating profits are therefore generally taxed initially at Swiss company level. For the German parent, distributions, disposals and special international tax provisions are particularly relevant.
- Swiss company as a separate taxpayer
- Shareholding held as a German business asset
- Review section 8b KStG for dividends and disposal gains
- Account for Swiss withholding tax
- Analyse trade tax separately
- Review the AStG for controlled companies
Section 8b KStG
Income from shareholdings received by a German corporation
Section 8b of the German Corporate Income Tax Act (KStG) provides a broad exemption for certain income from shareholdings and gains from the disposal of shares in corporations. This provision generally also applies to shareholdings in foreign corporations such as a Swiss AG or GmbH.
For exempt dividends and disposal gains, 5% is generally deemed to constitute non-deductible business expenses. At corporate income tax level, qualifying income from shareholdings is therefore often largely exempt, but not entirely free of tax.
For dividends, the ownership percentage must also be considered: small portfolio holdings do not automatically qualify for the participation exemption. The trade tax treatment must also be examined separately.
Review corporate income tax and trade tax separately
A participation exemption under section 8b KStG does not automatically resolve the trade tax treatment. Foreign dividends are subject to separate trade tax conditions and ownership thresholds.
Distributions
Dividends from the Swiss subsidiary to the German parent
Switzerland generally levies withholding tax on dividends. When a dividend is paid to a German parent company, relief from Swiss withholding tax must therefore be arranged alongside the German tax treatment.
The Germany–Switzerland tax treaty provides full relief in the source state for qualifying corporate shareholdings, provided that the required direct ownership percentage and minimum holding period are met, among other conditions.
For smaller shareholdings, a residual Swiss tax may remain. The specific relief must be coordinated with Swiss procedural and documentation requirements.
| Level | Review |
|---|---|
| Switzerland | Withholding tax and treaty relief |
| Tax treaty | Ownership percentage, holding period and entitlement to withholding tax relief |
| Germany – corporate income tax | Review section 8b KStG and the ownership threshold |
| Germany – trade tax | Review trade tax participation relief separately |
| Compliance | Coordinate Swiss relief or refund procedures and German accounting entries |
Exit
Selling the Swiss subsidiary
If a German corporation sells its interest in a Swiss AG or GmbH, the disposal gain is generally assessed under section 8b KStG.
Gains from the disposal of shares in corporations are generally excluded from the corporate income tax base; 5% of the gain is generally deemed to constitute non-deductible business expenses.
By contrast, losses, write-downs to lower going-concern value and certain financing losses connected with shareholdings are subject to specific tax restrictions. An exit should therefore not be assessed solely by reference to the gross disposal gain.
Swiss Partnership
German tax classification comes before taxation
For an interest in a Swiss partnership, the Swiss legal form’s name alone is not sufficient to determine the German tax treatment.
The foreign entity must first be compared with German legal forms to determine whether it is classified as a partnership or a corporation for German tax purposes.
If it is treated as tax-transparent in Germany, a proportionate share of business or permanent establishment income may be allocated to the German company on an ongoing basis. Taxation then does not depend on a subsequent distribution.
Entity classification
Liability, management, capital structure, profit rights and other characteristics of the Swiss entity must be compared with German legal forms.
Permanent establishment
An interest in a tax-transparent entity may result in Swiss permanent establishment income being allocated proportionately to the German company.
Tax treaty
The next step is to determine which state has taxing rights over the respective business profits under the treaty.
Different classifications can produce hybrid outcomes
Germany and Switzerland do not necessarily classify a legal form in the same way. The entity classification analysis should therefore be documented before the first German tax return is filed.
Swiss Permanent Establishment
A German head office with an operating permanent establishment in Switzerland
A Swiss permanent establishment is not a subsidiary. It remains part of the German enterprise both legally and for tax purposes. Business profits must therefore be attributed between the German head office and the Swiss permanent establishment.
Under the treaty, Switzerland may tax the profits attributable to the Swiss permanent establishment. Germany must then provide relief from double taxation under the applicable treaty rules.
- Determine the Swiss permanent establishment’s profit
- Allocate functions, assets and risks
- Review treaty exemption or the applicable relief method
- German tax returns remain necessary
- Address foreign permanent establishment profits separately for trade tax
- Coordinate German and Swiss accounting records
Treaty Profit Attribution
Economically attributable profit is decisive, rather than revenue alone
For a Swiss permanent establishment, it is necessary to determine which functions are performed there, which assets are economically attributable to it and which risks are associated with the Swiss activities.
The permanent establishment’s profit is derived from this analysis. For profit attribution, the German head office and the Swiss permanent establishment are treated, in important respects, as separate functional operations.
| Area | Typical question |
|---|---|
| Personnel | Which functions are actually performed in Switzerland? |
| Assets | Which assets serve the Swiss permanent establishment? |
| Risks | Which business risks are economically attributable to the Swiss activities? |
| Sales | Where are customers acquired, prices determined and contracts negotiated? |
| Central functions | Which services remain with the German head office? |
| Financing | What capital is economically attributable to the permanent establishment? |
German Treatment
Swiss permanent establishment profits still need to be addressed in Germany
Even where the treaty exempts certain active Swiss permanent establishment profits from the German tax base, the income must be correctly calculated, attributed and accounted for in German tax filings.
Treaty exemption also requires the relevant conditions to be met. For atypical activities or activities predominantly involving asset management, the applicable relief method should therefore be examined separately.
For trade tax purposes, profits attributable to a foreign permanent establishment of a German enterprise are generally deducted from the trade tax base, provided the statutory conditions are satisfied.
International Tax Rules
A Swiss subsidiary may be subject to German controlled foreign company rules
If the German company controls a Swiss corporation, sections 7 et seq. of the German Foreign Tax Act (AStG) must be reviewed. Certain low-taxed passive income may be attributed to the German company even if the Swiss subsidiary makes no distribution.
The analysis is not based on a blanket assessment of Switzerland. It depends on the specific income categories, control and effective tax burden.
- Review control of the Swiss company
- Distinguish active and passive income
- Determine low taxation under the German AStG
- Consider the 15% threshold
- Income inclusion may arise without a distribution
- Organise German filing obligations
Specific Swiss Consideration
Switzerland is neither an EU nor an EEA member
The German AStG provides a specific exception for certain companies in EU or EEA states that carry on substantial economic activity.
This statutory exception is limited to EU and EEA companies. A Swiss company therefore does not qualify for this particular provision merely because it has genuine substance in Switzerland.
Swiss substance nevertheless remains central to many other issues, particularly management, permanent establishments, actual functions and transfer pricing. For controlled foreign company taxation, however, the specific income category under the AStG must first be analysed.
A low Swiss tax rate alone does not trigger controlled foreign company taxation
In addition to low taxation, control and the statutory conditions for passive CFC income must be satisfied. A genuine operating business in Switzerland therefore requires a different analysis from a pure financing or asset-holding company.
Transfer Pricing
Dealings between the German parent and Swiss subsidiary must be on arm’s length terms
Cross-border business dealings between a German parent company and its Swiss subsidiary are subject to German arm’s length rules.
The transfer price itself is not the only relevant factor. Functions, assets and risks must first be allocated correctly between the enterprises in economic terms.
Management
Group management and administrative charges must reflect services actually provided and benefits received.
Financing
Loan amount, interest rate, maturity and creditworthiness must be assessed on an arm’s length basis.
IP & Software
Returns from trademarks, software and other intangible assets should reflect where the value-creating functions are performed.
Goods & Sales
Purchasing, sales, warehousing, market risks and warranty risks influence the appropriate allocation of profits.
Services
Intragroup services require a clear description of the services and a substantiated pricing approach.
Documentation
Contracts, functional analysis, invoices and accounting records should reflect the same economic structure.
German Compliance
Which information from Switzerland is needed for German tax purposes?
The Swiss company or permanent establishment maintains its local accounts under the applicable Swiss rules. However, the Swiss financial statements cannot always be used unchanged for the German tax return.
Depending on the structure, Swiss data may need currency conversion, tax adjustments, allocation by income category or additional information for permanent establishment profit attribution.
| Document | German purpose |
|---|---|
| Swiss annual financial statements | Starting point for shareholding, AStG or permanent establishment analysis |
| Account details / trial balance | Analysis of individual income categories and tax adjustments |
| Swiss tax assessment | Evidence of the actual Swiss tax burden |
| Dividend documentation | Section 8b KStG, trade tax and Swiss withholding tax |
| Shareholding documents | Ownership percentage, acquisition costs and corporate rights |
| Intercompany agreements | German transfer pricing and arm’s length analysis |
| Permanent establishment records | Allocation of functions and profits between Germany and Switzerland |
Financing
Equity, loans or ongoing intragroup financing?
Financing a Swiss subsidiary affects the ongoing allocation of profits, liquidity and the subsequent repatriation of funds to Germany.
For loans, the arm’s length principle, interest rate, creditworthiness and actual implementation are particularly important. The Swiss and German treatment of interest payments must also be coordinated.
Write-downs or defaults on shareholder loans may also be subject to specific deduction restrictions in Germany.
Place of Management
A Swiss subsidiary should genuinely be managed as a Swiss company
If a Swiss AG or GmbH is managed exclusively from the German parent’s location, and significant ongoing business decisions are actually made in Germany, the Swiss company’s tax residence may become relevant alongside the taxation of the shareholding.
The legal separation between German parent and Swiss subsidiary should therefore also be reflected in practice. Swiss corporate officers need genuine functions, and decision-making processes should match the documented governance.
This is particularly important for small subsidiaries where the same individuals serve as managing directors of the German parent and as officers of the Swiss company.
