Facebook appears to have paid substantially more in UK corporation tax last year than the £4,327 it handed over in 2014, accounts show.
While it said incurred a £4.2m tax charge – the sum remained a fraction of the £210m in UK revenue reported by the social network.
Facebook also reported a tax credit, within the business, of £15.5m. It is unclear whether the figure, which relates to stock options for employees, meant that it effectively paid nothing.
It lodged the figures months after pledging it would stop routing most UK sales through to a profit base in Ireland where corporation tax is charged at a lower rate.
