Google will give evidence to Commons Public Accounts Committee inquiry today into taxation of multinational companies.
Google's filings show it had $4 billion of sales in the UK last year, but despite having a group-wide profit margin of 33 percent, its main UK unit had a tax charge of just £3.4 million in 2011.
The company allegedly avoids UK tax by channeling non-U.S. sales via an Irish unit, an arrangement that allowed it to pay taxes at a rate of 3.2 percent on non-U.S. profits.
Big brands Amazon, Starbucks and Google were questioned by MPs today on their entirely legal tax avoidance methods.
MPs will today pour scorn at the UK tax affairs of the likes of Amazon and Starbucks, despite setting the rules within which they operate.
