Country profile
The world's 6th-largest economy and Europe's leading financial centre. Post-Brexit the UK is rebuilding its global trade posture while keeping deep capital markets, world-class universities, and the most fintech-friendly banking infrastructure on the planet. The non-dom regime ended on 6 April 2025 — replaced by a 4-year FIG regime, recalibrating the UK's appeal to internationally mobile high earners.
