June 26 (UPI) — President Donald Trump on Friday threatened to impose a 100% tariff on any country that enacts a digital services tax against a U.S. company.

The new tariff would be applied to all goods shipped into the United States and be levied on top of any other tariff already in effect for that country, Trump said in a post on Truth Social.

At least a dozen nations have digital services taxes, which are meant to limit the influence of large technology companies — especially large U.S. companies such as Apple, Amazon and Meta — and are being considered by several European countries, CNBC and Politico reported.

Canada last year rescinded a digital services tax hours before it was set to go into effect in order to restart trade negotiations with the United States, which Trump held back on until the tax was canceled.

“Please let this statement serve to represent that any Country that imposes such a Tax will immediately be met with a 100% TARIFF on any and all Goods sent to the United States of America,” Trump said in the post.

“This TARIFF will supersede Trade Deals made with the Country, whether implemented, signed, or not,” Trump said. “Additionally, the 100% TARIFF will be immediately imposed, if they proceed.”

Canada’s tax was to be levied against online marketplace and advertising services companies, as well as social media companies, but Trump called it a “direct and blatant attack” on the United States and canceled talks on the tax was rescinded.
