Tax expert Richard Murphy from Tax Research UK has told Daybreak that "there's no excuse" for tax avoidance and that celebrities who have been using schemes to do so "made a choice to cheat".
Comedian Jimmy Carr faced merciless teasing from his 8 Out Of 10 Cats team-mates after dominating the headlines this week over his tax affairs.
During tonight's recording, team captain Sean Lock waded in by telling Carr: "We all like to put a bit of money away for a rainy day, don't we? But I think you're more prepared than Noah."
And broadcaster Georgie Thompson chipped in: "On the plus side, at least you've been in a top 5 list of something."
8 Out Of 10 Cats is on Channel 4 at 10pm tomorrow.
The anti-austerity campaign group UK Uncut has said that individuals and corporations who it claims are avoiding paying tax are "clearly acting immorally" and urged the Government to clamp down on the practice:
The government must make Vodafone, Phillip Green, Amazon, Google, Barclays, Goldman Sachs- and all the other mega-rich individuals and corporations raking in massive profits- pay their fair share in tax. They must invest the money they raise in our public services, stop the cuts, and protect our jobs, pensions, welfare and other public sector goods and services. And they must do it now.
Lord Digby Jones, Former Minister for Trade and Investment, has said that the Prime Minister's comments about Jimmy Carr's tax arrangements may "come back to bite him".
He said that there are many "comfortable" but not "wealthy" people in the UK who avoid moderate amounts of tax, but should not be demonised.
Footballers, he says, are fair game:
Richard Murphy, an accountant who writes the blog Tax Research UK, has said that the Government needs to use its common sense and root out people whose tax bill does not match their earnings. Commenting on Jimmy Carr's tax arrangement (which he has vowed to change) he said:
There is a mismatch between economic reality andthe way [income] is being taxed. When that happens the Revenue should be ableto say: we are going to ignore all the artificial [tax avoiding] steps and instead tax theincome ... Whenever you put a rule in place the accountants find a way to break the rules. What we have to say is: rules are not good enough. We need a principle that lets us say (tax avoidance) is wrong.
Comedian Jimmy Carr has hinted that he will receive a dose of his own medicine on Channel 4's '8 Out Of 10 Cats' programme tonight:
Earlier on today I tweeted about my current situation. It's obviously serious but tonight I'm recording '8 Out of 10 Cats'.
So it's business as usual. I've dished it out enough times lets see if I can take it.
The Labour MP Michael Meacher has said that tax avoidance is happening on "an industrial scale" in the UK.
He told BBC News that under the proposed legislation "any device that was purely to avoid tax would be declared null and void."
He continued: "that would make it easier for the Inland Revenue to block these schemes which are now on an industrial scale".
He said that the vast majority of tax avoiders are ultra wealthy people rather than ordinary wage earners, and added that he pays his dues.
Prime Minister David Cameron said he would not be giving a "running commentary on different people's tax affairs" as "that would be wrong". He was responding to ITV News Political Editor Tom Bradby who asked if he thought Gary Barlow's tax affairs were morally wrong.
Mr Cameron also said it was important to distinguish between tax avoidance and tax evasion: the latter being illegal. He said the government would support for HMRC to pursue individuals engaging in "aggressive tax avoidance."
Comedian Jimmy Carr refused to expand on the statement he released on Twitter earlier when he arrived at the BBC studios to film his Channel 4 show 8 out of 10 Cats.
ITV News Political Editor Tom Bradby asked David Cameron if he thought Gary Barlow's "tax affairs were morally wrong and should he give back his OBE".
The Prime Minister dodged the question by saying he would not give a "running commentary on different people's tax affairs" as "that would not be right".
I made an exception yesterday because it was a very specific case where the details seem to have been published and it was a particularly egregious example of an avoidance scheme that seemed to me to be wrong and I made that clear.
I think the rules of the road here should be pretty frank. Tax evasion is illegal and should be pursued with all vigour by the authorities.
