Social network giant Facebook paid just £4,327 ($6,643) in corporation tax in 2014, its latest UK results show.
BBC reports that its most recent Companies House filing shows the company as making a pre-tax loss of £28.5m last year, but the firm also paid its 362 UK staff a total of £35.4m in share bonuses.
The share bonuses amount to £96,000 on average per UK Facebook employee.
It means Facebook's UK corporation tax bill was less than the tax the average UK employee paid on their salary.
The average UK salary is £26,500 on which employees pay a total of £5,392.80 in income tax and national insurance contributions.
In January, Facebook reported global fourth-quarter profits of $701m (£462m), a 34% increase on the same period a year earlier.
Total profits for the year were $2.9bn, almost double its profit for 2013.
Facebook said at the time that advertising revenue grew by 53% to $3.59bn, with nearly 70% of that coming from mobile ad sales.
The social networking giant says it now has 1.39 billion active users each month, a 13% increase from a year ago.
