UK tax authorities are reviewing the finances of George Cottrell, a close ally of Reform UK leader Nigel Farage. The scoping exercise by HM Revenue and Customs (HMRC) is focusing on his tax residency, income, and business activities. Farage has described Cottrell, 31, as “like a son to me,” and he has emerged as a key figure in the party’s leadership and fundraising network.
Cottrell, known as “Posh George,” leads a high-profile lifestyle, frequently travelling and using a £4 million property in west London. While he does not hold an official role in Reform UK, party insiders describe him as influential in policy, strategy, and the party’s growing social media presence. A recent poll put Reform UK at 35%, 15 points ahead of Labour.
Lawyers for Cottrell said he was unaware of any formal HMRC investigation. They confirmed he runs Geostrategy.com, which provides advisory services to governments and political parties, with offices in London, Washington, Podgorica, and Zurich. He is also writing a book on money laundering intended for law enforcement and policymakers, with proceeds going to charity.
Cottrell has financially supported Farage, including paying £15,000 for a US trip last year, while claiming to be tax resident in Montenegro. His mother donated £750,000 to the party in 2024. UK law allows overseas residents to fund party travel but limits other donations to UK-registered voters.
Sources say HMRC’s review is currently not a formal investigation and may conclude without further action if Cottrell is compliant. The review partly relates to his history of high-stakes gambling, which can trigger tax scrutiny due to large movements of money.
Cottrell served eight months in a US prison in 2017 for wire fraud linked to offering money laundering services online. At the time, he cited a multimillion-dollar gambling addiction as a factor in his illegal activity.
Officials are also examining Cottrell’s use of the west London property. Non-UK residents are exempt from UK tax on overseas income if they spend fewer than 90 days per year in the country. Longer stays can trigger residency status and require tax compliance. Public records list the property as owned by a company controlled by another Reform UK supporter, though Cottrell has reportedly used it frequently.
HMRC is understood to be reviewing Cottrell’s use of cryptocurrency exchanges, including Tether.bet and GT Holding, though his lawyers deny any involvement with these companies. Reform UK has advocated for political donations in cryptocurrency, and Cottrell is seen as a leading voice for crypto-friendly policies within the party.
Before entering politics, Cottrell worked in financial services, helping to manage a private office in Mayfair at age 19. He has claimed his wealth comes from an investment portfolio. He has lived between Montenegro and the UK and previously held a role in Ukip, Farage’s former party, before supporting Farage in the Reform UK campaign.
HMRC has not commented on the review, citing strict confidentiality laws that prevent confirming or denying investigations into identifiable taxpayers or businesses.
