UK Limited companies are widely used internationally. HMRC corporation tax, VAT thresholds, and PSC (people with significant control) reporting apply. Substance expectations have tightened.

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.

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

GBC (Global Business Company) and Domestic Companies are the standard structures. Substance requirements following OECD reforms must be considered; the GBC framework has evolved materially.

Resident banking is mature but onboarding is slow for non-residents. Many international founders use UK EMIs (Revolut, Monzo Business, etc.) alongside high-street accounts. 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.

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.

Local banks support resident and corporate accounts; KYC and source-of-funds requirements are real. Bordercase coordinates banking introductions.

Family reunification is supported. Schools (state, private, international) are widely available; competition for top schools is real.

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

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

Family inclusion is supported. International schools are available in major regions.
