The UK offers unique tax advantages for wealthy expatriates through non-domiciled status and remittance basis taxation. This comprehensive guide covers the UK tax system, recent policy changes, and optimization strategies for high-net-worth individuals.

What is Domicile?

Domicile of choice - Acquired by moving with intention to remain permanently
Deemed domicile - UK resident for 15 of last 20 years, or UK domiciled in last 3 years

Non-Dom Benefits

Remittance basis - Only pay UK tax on foreign income brought to UK
No UK inheritance tax on foreign assets (with exceptions)
Capital gains deferral on foreign assets
Offshore trust benefits for pre-arrival assets
