Company setup

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

Private Limited (Pte Ltd) is the standard structure. ACRA registration, a local resident director, and a registered office are required. Substance, accounting, and corporate governance standards are real.

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.

Banking

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.

Corporate banking has strong KYC and source-of-funds processes; relationship banking is common. Personal banking depends on residency status. Bordercase coordinates introductions through partners.

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

Family

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

Family relocation is well-supported via Dependant's Pass and LTVP routes. Schools (local, private, and international) are widely available; international schools are competitive.

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