DOO (limited liability) is the standard structure. Formation is well-documented and reasonably fast. Tax and VAT registration follow.

GmbH and AG are the standard structures. Cantonal variation in tax, registration, and substance treatment is real. Federal and cantonal compliance is precise.

GmbH and UG (haftungsbeschränkt) are common structures. Notary involvement is required for formation. Tax registration, trade registration (Gewerbeanmeldung), and German GAAP / tax accounting standards apply.

OÜ (private limited) is the standard structure, formed online via e-Residency or in person. Reporting obligations are real but proportionate; accounting partners are widely available.

Personal banking for residents is accessible. Corporate banking depends on activity. Bordercase coordinates introductions where useful.

Swiss banking has tightened materially since the 2010s. Personal accounts require residency or strong nexus; corporate banking requires substance and clear source of funds. Bordercase coordinates introductions through current partners.

Personal banking for residents is well established; certain non-resident structures take longer. SCHUFA history is relevant for residents. Bordercase coordinates introductions for cross-border cases.

Estonian banks have tightened KYC for non-resident e-residents; many international founders rely on EMIs (Wise, Revolut Business, Payoneer, etc.) for day-to-day banking. Local bank accounts typically require strong substance evidence.

Family inclusion on residency applications is supported. International schools are available in Podgorica and on the coast.

Family reunification is supported on most permits. Schools (public, private, and international) are widely available; international schools are well-established but selective.

Family reunification is well supported. Schools (public, private, bilingual, and international) are widely available; international schools are concentrated in major cities.
