Sp. z o.o. (limited liability) is the standard private entity. Online formation via S24 is possible; otherwise notary registration. Tax registration, VAT, and ZUS (social contributions) follow. CIT and the new estonian-style lump-sum CIT regime may apply.

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.

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.

OOD (LLC) and EOOD (single-shareholder LLC) are common structures. Formation is well-documented. Corporate tax is at a flat rate; VAT registration depends on activity.

Personal and corporate banking for residents is widely accessible. Non-resident structures take longer; documentation must be tight. Bordercase coordinates introductions where useful.
