In a post-COVID-19 world, anecdotal evidence suggests that individuals and families are relocating to new jurisdictions of residence. Equally, individuals have evidenced renewed vigor in acquiring and structuring assets across a range of jurisdictions. When the individual is a U.S. citizen and the place to relocate or acquire assets is the U.K., care must be taken to avoid common – and not so common – traps and pitfalls regarding taxation. In their article, Ed Powles, a Partner of Maurice Turnor Gardner, London and Emma-Jane Weider, the Managing Partner of Maurice Turnor Gardner, London, identify areas for which tax planning is crucially important prior to a move. Included are (i) tax residence and domicile rules for individuals, (ii) residence tests for trusts, companies, and charities, (iii) identifying areas for which income tax treaties do not necessarily provide relief against double taxation, and (iv) ways in which gift and estate planning, dissolution of marriages, forced heirship, and structures to own personal use residential real property are affected by the move.
