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.

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.

SA de CV (Sociedad Anónima) and S de RL de CV are the standard private entity types. Formation involves a notary, RFC (tax registration), and IMSS where staff are involved. Mexican tax residency is triggered by primary home and centre of economic interests.
