Global accounting firm, Deloitte has urged the UK government to provide clarity on the direction of the tax law reforms in the country stating that there have been mixed signals on the issue.

Chief executive and senior partner David Sproul of Deloitte UK said that a number of companies have delayed their plans to establish presence in the UK due to the lack of clarity on the tax laws. He pointed out that there have been conflicting signals from the Treasury and the House of Commons Public Accounts Committee (PAC) on tax laws.

"On the one hand, you've got a government pursuing a tax strategy to make the UK one of the most completive regimes. But then you've got a push by the PAC and by others to say... we want to make sure everyone's paying their fair share of tax and we'll determine what that fair share of tax is," Sproul said.

A panel involving cross-party lawmakers has urged the government to conduct a review of the existing corporate income tax laws and bring necessary reforms. They said that the current tax system is not working and needs reforms, urging the UK Treasury to look for scope for radical changes to the existing tax regime. The House of Lords committee on economic affairs released a report calling for transparency, greater oversight and a review of tax rules.
