A trade association for UK tech companies has claimed the government's Digital Services Tax (DST) will slow investment and raise consumer costs just as the government has drafted the measure into law.
After the chancellor Philip Hammond proposed a 2% levy on the revenues of companies like Google and Facebook in October, the government yesterday inserted the policy into its draft 2019/20 Finance Bill.
The move, however, has coincided with threats by the US government to investigate a similar levy on big tech revenue proposed by France. Current French proposals suggest imposing a 3% levy on firms with an annual revenue of more than 670 million, backdated to early 2019.
The response has made the UK's tech community wary over Britain's own plans to introduce such a tax, according to techUK, because it puts their members at risk of "retaliation" from the US president Donald Trump.
"There is no doubt that the system for international taxation needs to evolve to deal with a digitising economy," said techUK's associate director for policy, Giles Derrington.
"To do that we need smart and innovative solutions developed at a global level. As a revenue tax targeted on a narrowly defined set of companies, the Digital Services Tax is not one of those smart measures.
"The US Government has said that this proposal risks creating new non-tariff barriers to trade, and there is a real risk that the Government is putting the UK at risk of retaliation from the US Government that would hurt British businesses and consumers."
The DST will slap a 2% levy on the revenues of profitable search engines, social media platforms and online marketplaces that generate more than 500 million per year. This is expected to raise more than 400 million per year from 2022/23 and beyond.
"There is one standout example of where the rules of the game must evolve now if they are to keep up with the emerging digital economy," Hammond said when first announcing the measure last year.
"Digital platforms delivering search engines, social media, and online marketplaces have changed our lives, our society and our economy. Mostly for the better. But they also pose a real challenge for the sustainability and fairness of our tax system.
"The rules have simply not kept pace with changing business models and it is clearly not sustainable or fair that digital platform businesses can generate substantial value in the UK without paying tax here in respect of that business."
TechUK has also argued the there are too many unanswered questions about how the tax will work in practice, claiming it would lead to "bizarre outcomes" such as potentially raising costs which are in turn passed on to consumers, and reducing competition.
As part of the implementation, meanwhile, Her Majesty's Revenue and Customs (HMRC) will incur costs of up to 8 million to install new IT systems and processes, as well as hire additional staff, to administer the tax.
The European Union (EU), at one stage, also proposed imposing a 3% revenue tax on major multinational tech firms, but indefinitely delayed these plans after opposition from Denmark, Ireland and Sweden.
The contents of the Finance Bill, including changes to the IR35 rules, will undergo a consultation process before they are formally ratified in the 2019 Budget during autumn.
