US President Donald Trump has ordered an investigation into France’s planned tax on tech giants – a move that could result in retaliatory tariffs.
“The United States is very concerned that the digital services tax… unfairly targets American companies,” the US trade representative said.
The French parliament is expected to approve the new tax on Thursday.
It will target firms such as Google and Facebook with a 3% levy on revenue made inside France.
The tax is expected to raise about €400m ($450m; £360m) this year.
Any digital company with revenue of more than €750m – of which at least €25m is generated in France – would be subject to the tax.
