PR is more important than saving tax, perhaps. So Facebook has decided it needs to pay some tax in the UK.
Facebook paid £4.16m in UK corporation tax last year, as it expanded its business in the UK. It is a big increase on the £4,327 paid in 2014, which prompted an outcry from campaigners who argued it had paid too little. However, critics may also be riled by the fact that the company will receive a tax credit of £11m, which can be used to offset tax bills at a later date.
