Financing a foreign branch or subsidiary from a Swiss parent company
For rapidly expanding Swiss SMEs, endowing a foreign entity requires absolute mastery of FTA rules (intercompany loans, safe harbour rates) and a strategy to avoid capital erosion due to exchange fees.

- Financing a foreign branch from Switzerland is a simple internal transfer: the branch has no legal personality of its own. A subsidiary, as a company under local law, is instead financed through a capital contribution or a formalised intercompany loan.
- "Safe harbour" rates: the interest rates published each year by the Federal Tax Administration (FTA) serve as the benchmark for an intercompany loan. If the headquarters lends below the market rate, the tax authority increases the Swiss profit by the interest that should have been collected.
- Currency conversion weighs on the funding: a traditional bank generally applies a margin of 1.5% to 2.5%. To fund a subsidiary with 500,000 CHF, that represents 7,500 to 12,500 CHF.
1. Subsidiary or branch: what are the legal and financial differences?
For an SME based in Geneva or the canton of Vaud wishing to establish itself in neighboring France (Valserhône, Pays de Gex, Haute-Savoie), Germany, or Italy, the choice of legal structure determines how funds can legally cross the border (in accordance with the Swiss Code of Obligations - CO).
| Analysis Criteria | Branch (Zweigniederlassung) | Subsidiary (Independent Company) |
|---|---|---|
| Legal Personality | None (Extension of the Swiss parent company) | Local law company (e.g., SARL in France, GmbH in Germany) |
| Nature of funds transfer | Simple cash allocation (Internal transfer) | Equity contribution OR Formalized intercompany loan |
| Repatriation of profits | Free (Integrated into the Swiss headquarters' income statement) | Through dividends (possible withholding tax in the subsidiary's country; no Swiss withholding tax) |
2. Which FTA tax rules must be respected to avoid an adjustment?
When the Swiss parent company finances a foreign subsidiary (in Munich, Milan, or Paris) through a loan (debt) rather than a capital increase, the financial flows enter the radar of the Federal Tax Administration (FTA).
Thin capitalization (Circular No. 6a): a rule for Swiss companies
The FTA's Circular No. 6a (in French) on hidden equity (art. 65 of the Federal Direct Tax Act, DBG) targets Swiss corporations financed disproportionately by loans from their shareholders or related parties: the excess debt is treated as equity and the corresponding interest is not deductible.
It does not apply to a foreign subsidiary, which is not taxed in Switzerland: the subsidiary's indebtedness is governed by the thin capitalization rules of the country where it is based. Likewise, dividends paid by the subsidiary to the parent company are not subject to Swiss withholding tax, which only applies to distributions by companies domiciled in Switzerland. On the Swiss side, the point to watch is the interest rate on the loan granted by the parent company.
Safe harbour rates (transfer pricing)
For an intercompany loan to comply with the arm's length principle, the parent company can rely on the safe harbour rates published annually by the FTA. These rates are optional: a rate below them creates a rebuttable presumption that the arm's length principle has not been met, which the company can rebut, for example with a transfer pricing study. If the headquarters lends money at a rate lower than the market rate, the cantonal tax authority will increase the Swiss profit by the amount of interest that should have been collected.
3. How much does a cash transfer through a traditional bank cost?
Beyond the legal challenge, cross-border financing poses a major operational challenge: converting Swiss Francs (CHF) into Euros (EUR) or other currencies.
Imagine a Vaud-based SME that needs to inject 500,000 CHF into its new Lyon subsidiary. The common reflex is to initiate an international SWIFT or SEPA transfer from the e-banking of the headquarters' traditional bank.
| Transfer method | Exchange margin | Impact on 500,000 CHF |
|---|---|---|
| Traditional Swiss bank | Between 1.5% and 2.5% | Loss of 7,500 CHF to 12,500 CHF |
| ibani Business Solution | 0.15% | Cost of 750 CHF, i.e. a net saving of 6,750 CHF to 11,750 CHF |
The company's prolonged exposure to traditional banking methods also generates significant realized exchange losses (FX Loss) when closing consolidated balance sheets. To reduce this cost, you can convert your transfers at the real market rate, plus a margin of 0.40% to 0.15% depending on the amount, before funding your foreign branch.
4. How can these flows be optimized with ibani Business?
As a Swiss financial intermediary affiliated with the self-regulatory organisation SO-FIT, ibani allows SMEs to streamline this intercompany flow while protecting their seed capital.
- A dedicated Swiss IBAN: We assign a relay account (CH IBAN) to your SME. To endow your subsidiary, you make a simple, free domestic transfer from your Swiss bank to this IBAN.
- Transparent Interbank Rate: Upon receipt, the funds are converted at the true interbank market rate, plus a tiered margin of 0.40% to 0.15% depending on the amount (0.15% for 500,000 CHF). The savings on large financing volumes are immediate and substantial (as demonstrated above).
