France and the United States are locked in a slow-motion trade standoff over a tax that brings in less than a billion euros a year. Emmanuel Macron’s refusal to drop France’s Digital Services Tax, despite escalating tariff threats from the Trump administration, is the kind of geopolitical stubbornness that tends to send ripples through markets far bigger than the policy itself.

The core dispute is straightforward. France taxes big tech companies 3% on the revenue they generate from French users. The US views this as a targeted strike against American firms.

What France’s digital tax actually does

France’s Digital Services Tax, first enacted in 2019, applies to companies pulling in more than €25 million in French revenue and €750 million globally. In English: it’s designed to hit the Googles, Amazons, and Metas of the world, not your cousin’s Shopify store.

The tax generated roughly €756 million in collections during 2024. Proposals floated in 2025 suggested bumping the rate to 5-6%, which would significantly increase the burden on US tech giants operating in Europe.
