History. 0 of 6. In none of the six cases did a US tariff over the tax come into force. For Britain, France and five other countries the US announced tariffs and suspended them in the same notice.
Hunch.
The tariff market resolves on the Federal Register and the White House list of presidential actions: YES if, by 30 November 2026, extra US duties on goods from the United Kingdom are in effect and the order or notice names the Digital Services Tax as a reason. Tariffs announced but suspended, or starting after 30 November, do not count; Reuters and BBC News are the backup.
We looked for cases where the US named a trade punishment to make a country drop a tax that falls mostly on American tech firms, and that country's government had to decide. We found six since 2019, two of them British. Canada and India dropped their taxes, both within five weeks of the threat. Britain twice, France and five other countries kept theirs. Where the US announced tariffs over such a tax, it suspended them at once.
