Matt Brittin, head of Google Europe, Middle East and Africa said he would provide the figure at a later date after Meg Hillier, head of the public accounts scrutiny committee, demanded it four times.
"You don't know what you get paid?" the lawmaker said.
"Our there, taxpayers, our constituents, are very angry. They live in a different world, clearly, to the world you live in if you can't even tell us what you are paid," said the Labour opposition MP.
Britain's tax agency announced last month that Google would pay a 130 million pounds (166 million euro, USD 187 million) tax settlement for 10 years' operations in Britain where it makes 11 percent of its global sales.

Finance minister George Osborne hailed the agreement as a victory.
But there was a barrage of criticism, including from within Prime Minister David Cameron's own Conservative Party as the announcement coincided with a key tax filing deadline for many Britons.
It later emerged that Google had made profits of 106 million pounds on revenues of 1.18 billion pounds in Britain in the last 18 months alone and the Labour opposition claimed the giant was paying only "three percent tax".
He replied: "I understand the anger and understand that people, when they see reported that we are paying three percent tax, would be angry. But we're not. We're paying 20 percent tax".
Tom Hutchinson, Google Inc's vice-president for finance, told the committee hearing that the 130 million pounds was the largest tax settlement following audit ever paid by Google outside the United States.
The company thought it was "fair", he said.
Brittin also dismissed British press reports of higher tax payments being demanded of the company in France and Italy, where it has less business.
