Addison Lee founder owes £20.5m in tax after UK tribunal ruling

{"

John Griffin's Domicile Status and HMRC's Challenge":"John Griffin, the founder of Addison Lee, a London-based taxi company, had argued that he should be treated as a non-dom despite living in the UK since childhood. However, the UK's tax authority, HMRC, challenged this claim, arguing that England should be considered Griffin's home. The tribunal ruled in HMRC's favor, finding that Griffin had settled in England in every meaningful sense by 2013. The tribunal members stated that England was where Griffin had established his home, raised his family, built his business, accumulated his wealth, and organized his personal, social, and professional life.","

Legal Background and HMRC's Arguments":"Under UK law, a child's domicile is the same as their father's if the parents were married at the time of their birth. Griffin's father, Jack, had come to England from Ireland in search of work in 1935. As part of his appeal against HMRC's stance, Griffin had argued that his domicile should be the same as his father's. However, legal counsel for HMRC argued that Griffin's domicile status under UK law would have changed when his father's domicile of choice became England. They argued that this change had occurred some time before Griffin reached adulthood at the age of 21 in 1963.","

The Impact of the Ruling":"The tribunal's ruling makes Griffin's worldwide income from the period subject to UK tax rules. HMRC calculated that Griffin owes an additional £20.5m covering the seven-year period. This ruling caps off a long-running inquiry into Griffin's tax affairs and reflects the period after he sold Addison Lee to a private equity firm in 2013. The business was reported to be worth £300m at the time. The decision could have implications for other non-dom taxpayers and may impact the UK's tax system for individuals who have dual citizenship or strong ties to another country."}
