Company setup

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

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.

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.

Banking

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

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

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.

Family

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

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

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.
