Take That have come under fire after it emerged the pop stars have still not repaid the £20million they owe the taxman - one year after they were ordered to do so. Gary Barlow, Mark Owen and Howard Donald, who embark on their latest UK tour tomorrow, were told to pay back the cash 11 months ago after the 'investment' scheme they put millions into was ruled invalid. It is understood the trio are dealing directly with HMRC but have yet to stump up the cash. Scroll down for video . Fury: Take That members (from left) Gary Barlow, Howard Donald and Mark Owen have still not paid back the £20million they owe the taxman, one year after they were ordered to. The band begin their UK tour tomorrow . A source close to the band said: 'They are not appealing the decision, they are dealing directly with HMRC.' The delay has been criticised by The Taxpayers' Alliance, with pressure mounting further by the fact that TV sports presenter Gabby Logan has already fulfilled her promise to pay back all the money she owed from the 'tax shelter' scheme, according to the Sunday Mirror. Andy Silvester, campaign director, said: 'Everyone should play by the rules, and that means paying back on time if HMRC say so. 'However, the real moral of this story is that we desperately need to simplify the tax code to get rid of the loopholes that those with clever accountants can drive a Take That tour bus through. 'Politicians make an awful lot of noise about tax evasion and avoidance but are addressing the symptom rather than the cause.' The Take That trio have not appealed against last May's tax tribunal ruling that the Icebreaker scheme they paid millions of pounds into was created as a way of exploiting legal loopholes. Repaid: Other well-known clients who used the Icebreaker 'investment' scheme include TV sports presenter Gabby Logan (pictured right). Unlike Gary Barlow (left), she has already repaid everything she owed . Prime Minister David Cameron used a Take That lyric during Prime Minister's Questions, directed at Barlow, where he said 'We want your money back for good' as part of a pledge to get tax avoiders to return £5billion . Money poured into Icebreaker, which used investment in the music industry to gain tax reliefs aimed at boosting the UK's creative industries, did not attract income tax. Icebreaker officials claimed that the initiative was funding music, supporting little-known artists to famous names such as Sinead O'Connor. But it was ruled by Judge Colin Bishopp that the scheme was mainly for tax avoidance rather than investments. Many of the 1,000 clients who invested in Icebreaker claimed they did not know the scheme broke any rules. David Cameron has previously used a Take That lyric during Prime Minister's Questions, directed at Barlow, where he said 'We want your money back for good' as part of a pledge to have £5billion returned by tax avoiders. There is no suggestion Robbie Williams or Jason Orange took part in the Icebreaker scheme, which saw more than 7,000 repayment notices, totaling £1.6billion, issued by HMRC as part of a crackdown. A spokesman for Barlow, Owen and Donald said: 'I can confirm that Gary Barlow, Mark Owen and Howard Donald have now received confirmation from HMRC that their tax affairs are fully up to date.'
