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

Limited Şirket (LLC) and AŞ (Joint Stock) are common structures. Notary registration, tax registration, and a tax representative are typically required.

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.

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.

Personal banking for residents is broadly accessible; non-resident corporate banking has tightened. Source-of-funds and ownership clarity are central.

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.

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 reunification is supported on most routes. International schools (English, German, French, Italian) are available in Istanbul and Ankara.

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

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