Global coffee chain Starbucks says it is in talks with British government departments over how much tax it pays there.
It is one of several well-known firms that were criticised over the level of their corporation tax payments.
The firm admitted that it "needed to do more" in Britain on tax.
Meanwhile, Chancellor George Osborne has pledged more funds for the British authorities to tackle tax avoidance by multinationals.
He told the BBC an announcement would be made on Monday about the "extra investment in the part of the Inland Revenue that tackles tax avoidance by multinational companies".
A Public Accounts Committee report on the topic of how much tax multinational firms pay in Britain is due on Monday.
In November the committee took evidence from executives from Starbucks, Google and Amazon.
