Proof of activity and viability
One key legal requirement is demonstrating that your planned self-employment is genuine and viable. At the time of registering as self-employed (or when applying to convert/renew your permit), Swiss authorities will ask for evidence of your freelance business. You may need to show a business plan, contracts or client agreements, invoices for work done, or other proof that you have an active business that can financially sustain you (From EU/EFTA).
Examples of accepted proof include a valid VAT number, an entry in a professional register (if applicable), registration with social insurance as self-employed, accounting records of your business, or an entry in the commercial register (From EU/EFTA). The core idea is to convince authorities that you will not become a burden on social welfare – in other words, that your freelance income (or resources) will be enough to support yourself (and any dependents). For instance, when first applying for a self-employment permit, you must submit “documents proving that you are or will be self-employed and can support yourself and your family (e.g. your accounting records)” (Working in Switzerland as a foreign national).
Permit issuance and duration
If you are coming to Switzerland specifically to be self-employed (or switching your purpose of stay to self-employment), you should inform the cantonal migration office and apply for self-employment authorization.
For EU/EFTA citizens, once approved, the authorities will issue a B residence permit valid for five years (renewable) for the purpose of self-employment (Self-Employment). In practice, if you already hold a B permit (for example, obtained through a salaried job or family reunification), you are allowed to become self-employed without needing a completely new permit – but you should notify the cantonal authorities of your change in activity.
The good news is that an EU B permit includes full professional mobility: you can change employers or switch from salaried work to self-employment (and vice versa) without losing your residence rights (From EU/EFTA). Just ensure that at your next permit renewal you can provide evidence of ongoing gainful activity or sufficient income. (Cantonal migration offices can provide guidance in individual cases (From EU/EFTA).)
Exceptions and special cases
Note that there can be restrictions for certain professions or scenarios. Some regulated professions (e.g. doctor, notary, financial auditor) require specific authorization or qualifications before you can practice independently (Self-Employment).
These regulations can be federal or cantonal, so if your freelance work falls into a regulated field, check the requirements (licenses, diplomas, etc.) in that industry. Additionally, as of 2023, Croatian nationals (who recently gained full EU free movement rights) are subject to temporary quotas in Switzerland – meaning a Croat seeking self-employment might need a quota-limited B permit (From EU/EFTA). This is a special safeguard measure and may be lifted in the future, but it’s worth confirming the current status if it applies to you.
Other EU/EFTA nationals do not face quota limits for permits. Finally, non-EU nationals generally cannot freelance in Switzerland on a B permit unless they have a C permit or are a spouse of a Swiss/C-permit holder (Self-Employment) – but this does not concern EU citizens, who benefit from the free movement agreement.
