HMRC's action against tax avoiders continues to be unacceptably slow. The Liberty scheme, for example, began in 2005 and was closed down in 2009, but it has taken until 2014 to take this case to a tax tribunal. Up to £10 million of the total £400 million tax at stake may not be recoverable because in 30 cases HMRC failed to start inquiries into personal tax returns within the 12 month statutory deadline. HMRC should report on the progress it has achieved by using new powers granted by Parliament and show that it is using its existing powers with sufficient urgency. Recent changes to the UK tax regime have been challenged by international bodies like the OECD and European Commission as constituting 'harmful tax practices'. These changes make it easier for global companies to avoid paying tax in the jurisdictions where they make a profit. HM Treasury and HMRC should provide details of progress in identifying and addressing the ways that international tax structures are exploited, and set out the actual costs and benefits of recent changes to the UK's tax regime. It is amazing that HMRC made a £1.9 billion error when it established its baseline and set targets for its compliance work. This means HMRC has been overstating the extent to which its performance on compliance yield has improved and it inadvertently presented misleading information to Parliament. Astonishingly, this significant error in a key performance measure went undetected by HMRC's own system of governance and internal audit for three years

The Committee have made taxation a key area of focus during this Parliament and have published 20 reports on taxation and made over 100 recommendations to HM Revenue and Customs (HMRC) and HM Treasury aimed at improving HMRC's performance and strengthening confidence in the tax system. The Committee believe they have influenced the debate about multinational companies paying the appropriate amount of tax due, based on their transactions conducted within the UK; exposed serious problems with how the tax planning industry pushes aggressive tax avoidance schemes to businesses and wealthy individuals; helped to reform how HMRC tackles marketed tax avoidance schemes and settles tax disputes with large corporates; and challenged HMRC to provide a better and more even-handed service to customers. The Committee welcome the action that HMRC has taken in response to the recommendations and the progress that has been made. But much remains to be done; for example, HMRC must urgently transform its currently unacceptable levels of customer service. The Committee further welcomes the lead the UK Government has taken in this area on the international stage and call on the next government to continue this work and undertake to tackle both the industry and culture that surrounds and supports tax evasion and aggressive avoidance.

The Winterbourne View scandal in 2011 exposed the horrific abuse of people with learning difficulties and challenging behaviour in a private mental health hospital. Concerns were also raised about a number of other institutions. As a result, the Government committed to discharging those individuals for whom it was appropriate back into their homes and communities. However, since then, too many children and adults have continued to go into mental health hospitals, and to stay there unnecessarily, because of the lack of community alternatives. The number of people with learning disabilities remaining in hospital has not fallen, and has remained broadly the same at around 3,200. It was refreshing that NHS England took responsibility for this lack of progress and has now committed to develop a closure programme for large NHS mental health hospitals, along with a transition plan for the people with learning disabilities within these hospitals, from 2016-17. Discharges from hospital are being delayed because funding does not follow the individual when they are discharged into the community. This acts as a financial disincentive for local commissioners who have to bear the costs and responsibility for planning and commissioning community services. Delaying discharge has the effect of institutionalising people, making their reintegration into the community more difficult. Some local authorities' reluctance to accept and fund individuals in the community will be exacerbated by current financial constraints. The Department should set out its proposals for 'dowry-type' payments from NHS England to meet the costs of supporting people discharged from hospital.

This report summarises the key areas of the Committee's work over the past five years. It draws out the areas where progress has been made and where their successors might wish to press in future. The Committee has assiduously followed the taxpayer's pound wherever it was spent. Since 2010 they held 276 evidence sessions and published 244 unanimous reports to hold government to account for its performance. 88% of their recommendations were accepted by departments. In many cases they successfully secured substantial changes, for example with the once secret tax avoidance industry. They secured consensus from government and from industry that private providers of public services do have a duty of care to the taxpayer, and in pushing the protection of whistleblowers further up the agenda of all government departments. By drawing attention to mistakes in the Department for Transport's procurement of the West Coast Mainline, more recent procurements for Crossrail, Thameslink and Intercity Express have all benefited from more expert advice and a more appropriate level of challenge from senior staff. After discovery in 2012-13 that 63% of calls to government call centres were to higher rate telephone numbers, the Government accepted our recommendation that telephone lines serving vulnerable and low income groups never be charged above the geographic rate and that 03 numbers should be available for all government telephone lines. They also secured a commitment to close large mental health hospitals.

Inspired by a postgraduate course the authors have jointly taught at the University of Cambridge since 2001, Peter Harris and David Oliver use their divergent backgrounds (academia and tax practice) to build a conceptual framework that not only makes the tax treatment of complex commercial transactions understandable and accessible, but also challenges the current orthodoxy of international tax norms. Designed specifically for postgraduate students and junior practitioners, it challenges the reader to think about tax issues conceptually and holistically, while illustrating the structure with practical examples. Senior tax practitioners and academics will also find it useful as a means of refreshing their understanding of the basics and the conceptual framework will challenge them to think more deeply about tax issues.

Since the introduction of the income tax in 1913, controversy has raged about how heavily to tax the rich. Opponents of high tax rates claim that heavy assessments have negative incentives on the productivity of some of our most talented citizens; supporters stress the importance of the rich shouldering their "fair share," and decry the loopholes that permit many to escape their obligations. Notably absent from this debate is hard evidence about the actual impact of taxes on the behavior of the affluent. This book presents evidence by leading economists of the effects of taxes on the formation of businesses, the supply of labor, the form of executive compensation, the accumulation of wealth, the allocation of portfolios, and the realization of capital gains. Among its findings are that the labor supply of the rich remained unchanged in the face of large tax cuts in 1986, and that in late 1992 executives exercised billions of dollars' worth of stock options in order to beat the tax increases expected in 1993. The book also presents a history of efforts to tax the rich, a demographic snapshot of the financially affluent, and a road map to widely used tax-avoidance strategies. Does Atlas Shrug? will be of great interest to policymakers and interested citizens who want to know how much tax revenue could really be gained by increasing tax rates on the rich, or whether low capital gains tax rates really spur economic growth.
