LONDON, April 5 (Reuters) - A levy imposed by Britain on the revenues of big tech companies such as Google, Facebook and Amazon in 2020 as a stopgap measure pending an international tax agreement risks becoming permanent, a group of tax experts said on Wednesday.
The levy was introduced after concerns were raised about low levels of tax paid by some major tech companies, and raised 358 million pounds ($447 million) in its first year.
Without an agreement on how to allocate taxation rights that all major trading partners could sign up to, there was a real risk that the tax could effectively become permanent, the CIOT said.
"A revenue tax such as this is a blunt instrument that cannot accurately represent the tax on the profits generated in the UK," the CIOT's director of public policy, John Cullinane, said.
The tax is forecast to raise around 3 billion pounds by 2024-25, it noted.
