Founding a company in Switzerland: what cross-border commuters need to know

Cross-border commuters (Grenzgänger) hold one of the strongest starting positions for Swiss entrepreneurship: they know the market, they already work in the country, and founding a GmbH from CHF 20,000 or an AG from CHF 100,000 capital is open to them without relocation. What the standard formation guides skip is the commuter-specific part — the G permit, the residence requirement for signatories, and the question of which country collects social insurance and tax. This guide covers exactly that.

Who counts as a cross-border commuter

A cross-border commuter in the legal sense is a person who lives in one country and works in Switzerland, returning to their place of residence at least once a week — most commute daily from Germany, France, Italy or Austria. EU/EFTA citizens receive the G permit under the Agreement on the Free Movement of Persons; since 2007 they may live anywhere in the EU/EFTA area and work anywhere in Switzerland, the old border-zone restriction having been abolished for them. The permit is issued for five years when the underlying employment contract is unlimited, and it covers employed as well as self-employed activity. Third-country nationals can also be cross-border commuters, but only under far stricter conditions, including long-term residence in a neighbouring border zone.

Owning a Swiss company from across the border

Share ownership in a Swiss GmbH or AG is not tied to nationality or residence — a commuter living in Konstanz or Annecy can hold 100% of the shares. The catch sits in company law, not ownership law: Art. 718 para. 4 OR (for the AG) and Art. 814 para. 3 OR (for the GmbH) require that the company can be represented by at least one person resident in Switzerland — one individual signatory, or two people signing jointly.

A cross-border commuter, by definition, lives abroad and therefore does not satisfy this residence test, even with a G permit and a daily presence in the office. The standard solutions:

• A resident co-founder or employee receives signing authority alongside you.
• A resident director mandate: a Swiss fiduciary professional joins as managing director or board member with signing authority. This is a routine, priced service — see our director and board mandates.

The company also needs a registered office in Switzerland from day one; a business address in Zug or Zurich satisfies this requirement and gives the company a legal domicile for official correspondence.

The G permit when the company employs you

Employment in your own company changes the permit mechanics in a way many founders miss. Once your GmbH is registered, it becomes your employer: the company applies for your G permit with the cantonal migration office, submitting the employment contract. For EU/EFTA citizens this is an entitlement, not a discretionary decision — approval is the norm and processing takes a few weeks.

If you operate as a self-employed cross-border commuter instead (for example as a sole proprietor before incorporating), you apply for the G permit yourself and must demonstrate a viable self-employed activity — business plan, accounting records, client contracts. Founding a GmbH is often the cleaner route precisely because the employer–employee relationship is easier to document.

What differs for commuters — at a glance

Social insurance: one country, clear rules

The EU coordination regulation decides which country's social insurance system applies, and the principle is single-country coverage. A commuter employed by their Swiss company and working in Switzerland pays into the Swiss system: AHV/IV/EO, unemployment insurance, occupational pension (BVG) and accident insurance are all deducted from the Swiss salary.

Two situations pull the answer back to the residence country, and both matter for founder-managers:

• Substantial activity at home. If 25% or more of your working time or remuneration arises in your country of residence, the residence country's system applies to your entire income — including the Swiss salary. Your Swiss GmbH would then have to register as an employer in Germany or France and pay foreign social charges, which are typically higher.
• Telework. The multilateral framework agreement in force since 1 July 2023 relaxes this for home office: up to 49.9% cross-border telework is possible without switching insurance country, provided both states have signed (Switzerland and all four neighbours have, as of 2026) and the employer applies for the A1 certificate accordingly.

Plan your working pattern before formation, not after — retroactive reclassification into a foreign social system is one of the most expensive surprises in cross-border structures.

Formation process in brief

The formation itself follows the standard Swiss playbook, described in detail on our Swiss company formation service page. Condensed to the commuter-relevant essentials:

1. Choose the legal form

   GmbH with CHF 20,000 fully paid-in capital suits most owner-managed businesses; the AG with CHF 100,000 (minimum CHF 50,000 paid in) adds prestige and shareholder anonymity.

2. Secure the Swiss substance

   Registered office address, and a resident signatory arrangement if no co-founder lives in Switzerland.

3. Deposit capital and notarise

   Capital goes into a blocked account at a Swiss bank; a notary certifies the incorporation deed and articles of association.

4. Commercial register entry

   The cantonal commercial register office enters the company; with clean documents the whole formation takes two to three weeks.

5. Register as employer and apply for the G permit

   The company registers with the compensation office and an accident insurer, then files your G permit application with the employment contract.

When founding as a commuter does not make sense

Founding in Switzerland is not automatically the right structure for every commuter. If your customers, suppliers and daily management would all remain in Germany or France, the company risks being treated as tax-resident there under the place-of-effective-management rule — you would carry Swiss formation and administration costs while gaining no Swiss tax position. The same applies if the budget does not cover genuine substance: a resident director mandate and a real registered office are recurring costs, and a letterbox setup without them invites challenges from both tax administrations. In these cases, staying employed in Switzerland while running a home-country business, or comparing jurisdictions first, is the honest recommendation — our Switzerland vs Germany comparison sets out the numbers side by side.

Next step: clarify the three commuter-specific points — resident signatory, G permit route, working-time split — before you book the notary. Everything else in the formation is standard and fast.
