Jeremy Corbyn has vowed to stop multinational companies offshoring their tax bills to “lower tax regimes” with measures to force them to pay their fair share in the UK.
The Labour leader met workers at an Amazon depot in Sheffield as he warned big companies they would have to pay taxes on all operations in the UK.
Labour expects the measures would raise £6.3 billion for the exchequer in 2024 to help pay for its manifesto plans to nationalise key utilities in a “green industrial revolution”.
Mr Corbyn and shadow employment rights secretary Laura Pidcock set out plans to clamp down on “enablers of tax dodging”, increase HMRC targeted audits and establish an inquiry into the finance sector.
The Labour leader told reporters: "We're here to say to big companies that operate in Britain that in future you're going to have to pay taxes on all your operations in this country - you will not be able to offshore your tax bill to some lower tax regime.
"I think these are just basic issues of social justice."
He said zero-hours contracts would be a "thing of the past" under Labour, and everyone in work would know "exactly what their basic income is going to be".
If Labour wins the December 12 election, it would introduce a 20% offshore company property levy, require greater scrutiny of MPs’ tax affairs and scrap non-dom status which gives tax advantages.
Labour also highlighted other existing policies to end in-work poverty with plans to give a £10-an-hour minimum wage for all, ban zero-hours contracts and give every worker full rights from their first day on the job.
The decision to have made the speech outside the Amazon depot is a combative one, as Mr Corbyn has long sparred with tech giants.
He previously wrote a birthday card to Amazon founder Jeff Bezos wishing the company “many happy tax returns” and demanding it pays more UK tax and improve working conditions.
An Amazon spokesman said: “These claims about Amazon are false. The Government wrote the tax laws and they are designed to encourage investment, and we are investing heavily in creating jobs and infrastructure across the UK – more than £18 billion since 2010.
“This investment helped contribute to a total tax contribution of £793 million during 2018 – £220 million in direct taxes and £573 million in indirect taxes.
“This year we announced plans to create 2,000 new jobs in the UK, taking our total workforce to over 29,500. Our associates receive industry-leading pay, with all employees earning at least £9.50 to £10.50 an hour depending on location.”
