Donald Trump’s threat to impose 100% tariffs on countries taxing American digital companies has reopened a transatlantic dispute that the latest EU-US trade settlement did not resolve: whether Washington can use market access to constrain Europe’s tax and regulatory sovereignty.
The fragile EU-US trade truce is facing a new test after President Donald Trump threatened to impose a 100% tariff on goods from any country that applies a digital services tax to American companies.
In a social-media post on 26 June, Trump said the penalty would override trade agreements already negotiated or signed. The threat was directed broadly at countries taxing US digital businesses, but he singled out European governments and revived a dispute that has repeatedly centred on France’s levy on large technology groups. The reported threat covered “any and all goods” sent to the United States, rather than a narrow list of products chosen to match the value of the tax.
The European Commission responded that national digital taxes are legitimate and non-discriminatory, and warned that the EU would act “swiftly and decisively” against unjustified unilateral measures. That response, given as Washington’s latest threat emerged, matters because it frames the dispute as a defence of European regulatory autonomy, not simply a quarrel over tariff rates.
A truce with a large gap
The confrontation exposes what the transatlantic tariff settlement left unfinished. The deal capped most US tariffs on EU exports at 15%, while Europe moved to reduce duties on specified American goods. Yet digital taxation, platform regulation and several other non-tariff disputes remained outside the bargain.
That omission was always politically dangerous. Washington has long argued that digital services taxes fall disproportionately on US companies because American groups dominate global search, social media, online advertising and digital marketplaces. European governments counter that the measures respond to a mismatch between where digital companies generate revenue and users, and where their profits are ultimately taxed.
France’s tax, introduced in 2019, applies a 3% levy to certain digital revenues earned in the country by groups exceeding French and global turnover thresholds. It is based on activity, rather than corporate nationality, but its commercial incidence falls heavily on large US businesses. Trump had already threatened 100% tariffs on French wine unless Paris withdrew the measure. The new warning widens that pressure to every product exported by any country that maintains such a tax.
For Brussels, the immediate difficulty is institutional. Most digital services taxes are national measures, while trade retaliation against the EU would affect the bloc collectively. France may be the most visible target, but a sweeping US tariff could disrupt manufacturers and exporters in member states that did not enact the tax at issue.
Tax is not regulation
The distinction between taxation and regulation must also remain clear. The EU’s Digital Markets Act and Digital Services Act are regulatory frameworks, not digital services taxes. They govern market power, platform conduct, content systems and user protection. Washington has nevertheless often grouped European digital taxes and technology rules together as burdens directed at American firms.
That broader pressure is especially sensitive as Brussels tries to reduce its dependence on US technology infrastructure. Recent proposals for European cloud-procurement rules have already raised questions about access for American providers, while disputes under the Digital Markets Act have affected Apple, Meta and other US companies.
If the tariff threat expands from taxes to regulation, the conflict would move beyond fiscal policy. It would become a direct contest over whether the EU can set internal-market rules for companies operating in Europe without facing trade penalties from their home government.
The credibility problem
There are also practical questions surrounding Trump’s warning. A 100% tariff on all goods from a targeted country would be far more disruptive than the calibrated retaliation traditionally used in tax disputes. It would increase costs for US importers and consumers, interfere with integrated supply chains and risk immediate European countermeasures.
The mechanism is not yet clear. Previous US investigations into digital services taxes used Section 301 of the Trade Act, a process involving investigation and the identification of responsive measures. A social-media declaration does not by itself settle the legal basis, timing or product coverage of a tariff.
But uncertainty is part of the pressure. Companies cannot assume the threat will disappear, especially when the White House has tied it to the approaching timetable for implementing the wider trade deal. EU exporters therefore face two risks: the agreed 15% framework may not provide the stability they expected, and national policies outside the agreement may trigger additional duties.
Earlier pressure on the EU-US settlement over threatened forced-labour tariffs had already shown that new US trade actions could accumulate on top of the headline agreement. The digital-tax confrontation is more politically explosive because it touches revenue, sovereignty and the regulation of powerful technology companies at once.
The next step will show whether the threat is intended to force negotiations, trigger a formal US trade process or produce immediate tariffs. For the EU, however, the strategic question is already present. A trade deal that can be superseded whenever Washington objects to a European tax or regulation is not a durable truce. It is a temporary tariff ceiling subject to continuing political leverage.
