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.

Domestic companies and IBCs are common in international structures.

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.

Banking is selective. Bordercase coordinates banking introductions through current partners.

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.

CBI can include qualifying dependents.

Family relocation is supported on the work and start-up visa routes; schooling and healthcare access follow the main applicant's residency.
