Rule coverage

What the rules say about Switzerland

The rules below are the ones most likely to shape a stay in Switzerland, in plain words and with the source behind each one. Your own report tells you which of them apply to you.

1. Significant issueTax residency

   30 days of working from Switzerland makes you a Swiss tax resident, not 90 or 183

   Under Article 3 of the Federal Direct Tax Act (DBG/LIFD) and the matching cantonal rule, 30 or more days of continuous stay while engaged in gainful activity is enough to make you a Swiss tax resident, taxed on worldwide income and assets. This is the single most common trap for a working stay in Switzerland, a three-month nomad stint is almost certainly Swiss tax residency, and it catches people who planned around the 90 or 183-day thresholds common elsewhere. Federal tax tops out at 11.5 percent marginal, but combined federal, cantonal and communal rates run roughly 21.9 percent in Zug up to around 43 percent in Geneva, and the exact figure depends on your canton and commune.

2. Significant issueImmigration and visa

   Past 90 days on a short-stay status, you are overstaying and working without authorisation

   Schengen short stays, visa-free or on a C visa, max out at 90 days in any 180. Past that without a permit you breach the Foreign Nationals and Integration Act (AIG/LEI). Switzerland cross-checks entry and exit, so this is real enforcement risk, not a theoretical one, and reported consequences include fines, removal and a Schengen-wide entry ban recorded in the SIS. Longer than 90 days needs a permit regardless of nationality, and for a remote worker there is no nomad visa to reach for, only the routes covered in the right-to-work and residency findings.

3. Significant issuePermanent establishment risk

   Signing contracts or managing the business from Switzerland creates real tax residency risk for the employer

   Swiss courts look at where a company is actually managed, not just where it is registered. A foreign company with little substance abroad that is effectively managed from Switzerland can be deemed a Swiss tax resident company under place-of-effective-management doctrine and taxed on worldwide profits, or at minimum taxed as a Swiss permanent establishment on attributable profit. Habitually signing contracts or making management decisions from Switzerland is exactly the fact pattern that triggers this.

4. Significant issueMoving your company

   Keep running your foreign company from Switzerland and you risk dragging its tax residency here with you

   If you relocate to Switzerland but keep managing your existing foreign company from here, day to day, Swiss courts can deem that company effectively managed from Switzerland under place-of-effective-management doctrine. A company with its statutory seat abroad but little genuine foreign substance, run from your new Swiss base, can be treated as Swiss tax resident and taxed on worldwide profits, or at minimum taxed as a Swiss permanent establishment on attributable profit. This is the classic trap for a founder who relocates personally but does not restructure the company. The lack of Swiss CFC rules does not help you here, this is a residency question about the company itself, not a CFC attribution question.

5. Significant issueRight to work

   Serving Swiss clients or taking up Swiss employment without a permit is unambiguously not allowed

   Whatever tolerance exists for quiet remote work for a foreign employer, taking up Swiss employment or providing services to Swiss-market clients without the right work authorisation is not in that grey zone at all. This is the one bright line in an otherwise fact-specific area, and it applies regardless of how short the stay is or which entry status you hold.

6. Needs checkingResidency routes

   Third-country employment residency runs through a hard annual quota and a labour market test

   For 2026 the federal ceiling for third-country nationals is 8,500 permits, split 4,500 B permits and 4,000 L permits, plus a separate ring-fenced allocation of 3,500 for UK nationals specifically, 2,100 B and 1,400 L, reflecting the UK's post-Brexit status outside the AFMP. On top of the quota, employers must clear a labour market test and applicants generally need to meet a highly qualified bar of a degree plus relevant experience. This is a genuinely constrained route, not a formality.

What tends to surprise people here

• 30 days of working presence trigger Swiss tax residency, far stricter than the usual 183-day rule
• No digital nomad visa, and a 2026 quota limits third-country work permits
• Cantonal tax rates and lump-sum minimums vary widely across all 26 cantons
