On April 23, 2026, HMRC published its annual digital services tax statistics, confirming the UK's 2% levy on large online platforms raised £944 million in 2025-26 — a 17% increase from £808 million the year before. The number of paying companies rose from 28 to 32, with a growing share headquartered outside the United States. By revenue, the UK DST remains the largest such levy in the world.
For the Treasury, the numbers are unambiguously good. For trade negotiators, they are not.
A Tax That Performs Far Above Its Own Projections
When the Finance Act 2020 introduced the DST, HM Treasury estimated it would raise approximately £275 million per year. It is now raising more than three times that without any broadening of scope. HMRC's statutory review, published in November 2025, found no evidence of avoidance or fraud. The digital advertising market the DST partly targets grew to over £35 billion annually by 2024, suggesting the levy has not suppressed sector expansion. Online marketplace usage among UK consumers rose from 81% to 90% between 2019 and 2024.
That record deserves a fair hearing before the trade argument is made. The DST applies at 2% on revenues — not profits — and only above thresholds of £500 million in global turnover and £25 million in UK-derived revenues. Companies absorbed it rather than materially repricing services. A levy that raises nearly £1 billion per year at an implementation cost of £6.3 million, per the November 2025 review, is not obviously disproportionate on fiscal grounds. The steel-man case for maintaining it is straightforward: it captures value created by platforms serving UK users who, absent the DST, would face no meaningful UK tax liability.
The Scaffold That Never Arrived
The problem is that the DST was never designed to be permanent. The Finance Act 2020 committed the government to removing it "once an appropriate global solution on the reallocation of taxing rights is in place." That solution was the OECD's Pillar One framework — a multilateral agreement that would have replaced unilateral DSTs with a unified set of allocation rules for large multinationals.
Pillar One is now effectively dead. President Trump's executive order of January 20, 2025 withdrew the United States from the OECD global tax agreement, removing the one counterparty whose participation was non-negotiable. Without US buy-in, Pillar One cannot function. Without Pillar One, the UK government's own statutory condition for removing the DST cannot be met — unless it chooses to revise that condition unilaterally.
Other jurisdictions have drawn the obvious conclusion. Canada withdrew its digital services tax in June 2025 after Washington made clear it would not advance trade talks while the levy remained in place. India and New Zealand abandoned their proposed DSTs under similar pressure earlier. The UK has held its position.
Section 301 Is Not a Hypothetical
The United States has already put the UK DST on a formal legal track. In January 2021, the US Trade Representative determined the UK's levy was "unreasonable or discriminatory" and "burdening or restricting US commerce" — making it actionable under Section 301 of the Trade Act of 1974. Retaliatory tariffs were prepared but held in suspension as Pillar One negotiations continued. With that diplomatic cover gone, the suspension is no longer obviously warranted.
The Computer and Communications Industry Association made this explicit in April 2026, responding directly to the HMRC receipts announcement. CCIA Vice President Jonathan McHale stated: "Absent a clear path to phase out this distortive regime, countermeasures will be inevitable." The CCIA further noted that the UK "remains out of step: as others move away from digital-specific taxes, it continues to rely on a DST that is both discriminatory and growing."
A Complication the Trade Narrative Omits
The rising share of non-US payers adds texture the CCIA framing tends to elide. Freedom of Information analysis by TaxWatch UK found that 37% of in-scope corporate groups are not US-headquartered, and 28% of actual payers are non-US companies. The expansion from 28 to 32 paying firms in 2025-26 likely reflects platforms based in Asia and Europe whose UK revenues have crossed the thresholds.
This somewhat undermines the argument that the DST functions exclusively as an American burden. It does not, however, neutralise the Section 301 exposure. US trade law assesses whether a measure "disproportionately affects" US commerce — and a levy concentrated on search, social media, and online marketplaces, sectors dominated by US-headquartered firms, still satisfies that threshold regardless of whether some non-US platforms also pay.
What the Revenue Record Actually Signals
The UK government must now decide what the DST actually is. If it was always an interim measure pending global reform — and that reform is no longer reachable on any near-term horizon — then the DST has become something else by default: a permanent structural levy on a sector central to UK economic growth and investment attraction.
That might still be the right policy choice. But it should be made explicitly, with a clear-eyed assessment of trade risk and a credible account of what replaces OECD Pillar One as the off-ramp. A record revenue year is a moment for transparency, not complacency. The scaffold was always meant to arrive. It hasn't. London should say so — and price in the consequences before Washington does.
