(Telecompaper) Facebook has announced plans to start billing customers in the UK from its local subsidiary, rather than through Ireland, a move that is expected to make the company liable for higher taxes in the UK, the Guardian reports. Starting in April, the social network said it will change its policy so that revenue generated from its largest advertisers displaying content on Facebook will be routed through the UK rather than Ireland. The company added that the move had been planned for some time and comes in response to changes in UK tax law. Where Facebook UK deals with advertisers directly "adding value" to the transaction, advising companies and planning ads, it will invoice through the UK. Smaller businesses that use the social network's online ad buying tools will still be invoiced through Facebook Ireland, which will remain the company's international headquarters handling all business outside of North America.
