Billionaire trader Alex Gerko lost a legal battle at the UK Supreme Court on June 17 over a £22.5 million ($30.2 million USD) tax bill. Five judges ruled that Gerko and other traders must pay income tax on their share of trading profits from a fund at GSA Capital Partners between 2010 and 2015. Gerko had argued the tax authorities were imposing “massive double taxation” on the deferred profits.
Court Rules Against Trader on Tax Liability
The UK Supreme Court rejected Gerko’s argument that deferred trading profits should not face income tax. Judges ruled on Wednesday that traders must pay income tax on their share of fund profits earned during the 2010-2015 period. The total tax bill stands at £22.5 million ($30.2 million USD).
What Gerko Argued
Gerko claimed the tax authorities were imposing double taxation by taxing deferred profits as income. He contended that the profits had already been taxed or should not face income tax treatment. The court disagreed, finding that income tax applied to the traders’ share of profits from the GSA Capital Partners fund during the specified years.
Impact on UK Tax Law
The ruling strengthens the UK tax authority’s position on how deferred trading profits are taxed. The five-judge panel decision sets a precedent for similar cases involving traders and fund managers. The outcome signals that British tax law treats such deferred profits as taxable income, not capital gains or other categories.
Final Thoughts
Gerko’s loss at the UK Supreme Court means he must pay £22.5 million in income tax on deferred trading profits. The ruling reinforces tax authority enforcement and may affect other traders facing similar claims.
