Company setup

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.

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

Banking

Personal and corporate banking for residents is broadly accessible. Source-of-funds documentation matters for non-standard cases. Bordercase coordinates banking introductions.

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.

Family

Family reunification is supported. Schools (public, private, English, German, French) are concentrated in Sofia, Plovdiv, and Varna.

Family reunification is supported. Schools (state, private, international) are widely available; competition for top schools is real.
