Former President Donald Trump has warned the United Kingdom faces tariffs if it doesn't abandon its digital services tax on US tech companies, escalating tensions between the two nations. This move occurs amidst broader strains in the US-UK relationship and ahead of a state visit by King Charles III.

Digital Services Tax at the Heart of Dispute

Trump’s threat, delivered from the Oval Office, centers around the 2% levy introduced in 2020. This tax targets the revenues of large US tech companies based on their digital activity within the UK. The tax generated over £800 million in revenue for the UK in 2024-25.

Trump's Criticism of the Tax

Trump characterized the tax as an attempt by the UK and other nations to unfairly profit from American companies, stating they are trying to ‘make an easy buck’ at the expense of the United States. He indicated any retaliatory tariffs would be ‘more than what they’re getting’ from the digital services tax.

Tax Details and Scope

The digital services tax specifically targets companies with global revenues exceeding £500 million, with a minimum of £25 million originating from UK users. Despite discussions during negotiations for the UK-US trade deal finalized in May 2025, the tax remained unchanged.

Broader US-UK Relationship Strains

This latest outburst from Trump adds to a growing list of strains in the bilateral relationship. Recent disagreements include differing stances on the conflict in the Middle East, where UK Prime Minister Sir Keir Starmer has ruled out British military involvement.

Starmer's Position on Military Involvement

Starmer addressed the pressure directly in Parliament, reaffirming his commitment to prioritizing UK national interests and refusing to be drawn into what he described as ‘not our war’.

Previous Warnings and Trade Deal Implications

Trump has previously hinted at altering the terms of the trade agreement, suggesting it is not a fixed document. This threat mirrors similar warnings issued to other European countries – including France, Italy, and Spain – that have implemented their own digital taxes.

In August 2025, Trump used his Truth Social platform to denounce these taxes as discriminatory, vowing to impose ‘substantial additional tariffs’ on nations that do not remove them.

Timing and King Charles III's Visit

The timing of this renewed threat is particularly sensitive, occurring just ahead of a planned state visit to the US by King Charles III and Queen Camilla, intended to commemorate the 250th anniversary of American independence. While meant to symbolize a strong alliance, Trump’s rhetoric casts a shadow over the event.
