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.

Domestic companies and IBCs are common in international structures.

Portugal supports Lda (private limited) and SA (public limited) structures. Tax registration, social security registration, and a Portuguese tax representative are typically required. Substance, accounting, and reporting obligations are real.

S.R.O. (private limited) is the standard entity, with relatively low minimum capital and well-established formation processes. VAT registration depends on activity.

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.

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

Personal accounts are accessible to residents and many non-residents; documentation is structured and predictable. Corporate banking depends on company structure and intended activity; Bordercase coordinates with banking partners for introductions.

Resident banking is straightforward; corporate banking varies by activity. Bordercase coordinates introductions for cross-border cases.

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

CBI can include qualifying dependents.

Family reunification is supported on most residency routes. Schools (public, private, and international) are widely available; the public system is generally accessible to legal residents.

Family reunification is supported. International schools are available in Bratislava.
