Written evidence submitted by Christopher J Wales

Submission by Christopher J Wales, Senior Managing Director, FTI Consulting and former member of the Council of Economic Advisers at HM Treasury

EXECUTIVE SUMMARY

This note welcomes the Committee's initiative and the recent reports of the Mirrlees Review team and the OECD on taxation policy. Taxation policy outcomes can be significantly influenced, not just by principles and objectives, but by the structures, processes and governance arrangements that surround the policy process itself. The author is currently engaged on a multi-country study that examines, on a comparative basis, the way in tax policy is made and the influence that the process exerts on policy outcomes. The initial findings of that work are reported here.

1.  INTRODUCTION

1.1  I welcome the inquiry launched by the Treasury Committee into the fundamental principles of tax policy. As the Announcement notes, the inquiry follows closely on from the publication of the Mirrlees Review and the OECD report on Tax Policy Reform and Economic Growth. Each of these publications makes a significant contribution to the discussion of policy substance. They provide a reminder that good tax policy requires a complex marrying together of political, economic and legal considerations and give some sense of the depth of thinking and analysis that is required to develop effective policy. They also add valuable evidence of the influence exerted on policy outcomes by the way in which tax policy is made.

2.  THE ROLE OF TAXATION POLICY

2.1  The growth trajectory of the UK economy has been significantly affected as a result of the international financial crisis. Monetary policy was used successfully by the Government and the Bank of England during and immediately after the crisis to protect both individuals and businesses. However I believe that there is now scope and indeed a need for taxation policy to be used more fully to put the UK economy back on a path of sustainable growth.

2.2  Taxation is primarily a method of raising money to fund government expenditure but it can have a profound effect on behaviour. The imposition, variation, reduction or elimination of taxes, whether of a general or specific nature can and does have consequences for economic activity: consumption, investment, saving, job creation etc. I believe that, in principle, the broad thrust of taxation policy should be towards neutrality but I accept that, where a taxation instrument is likely to be the most effective in dealing with a particular market failure, an exception to this general rule should be made.

2.3  Governments can, of course, choose to use the tax system to influence behaviour or not but in either case, effective tax policy requires the consequences of both action and inaction in the tax policy sphere to be properly understood.

3.  THE PROBLEM WITH PRINCIPLES

3.1  This note starts from the premise that there are, in fact, relatively few absolutes in terms of principles that should underpin the tax system; and that it is easy to confuse principles with features. For example, the Government might have an objective of creating a tax environment in which business can prosper and in doing so, might set a target of imposing a lower effective rate of tax on businesses operating in the UK than those in the rest of the EU. Thus competitiveness might become a goal for policy-makers and ultimately a feature of the UK business taxation but this does not make it a principle underpinning the tax system.

3.2  Fairness might be a good principle to underpin the system but what does it mean? It is a loose concept, to which we all might subscribe, but capable of many different interpretations.

3.3  We can, of course, give more precision to the principle of fairness. We can develop and use the more precise concepts of horizontal equity and vertical equity that have been widely explored in the relevant literature. We can broaden its scope to include the newer concept of intergenerational fairness. But essentially, even these concepts are only guides to the outer limits of where policy should go rather than active principles with which to drive the development of policy.

3.4  The UK tax system, as it stands today, reflects the economic, social and legal history of our country. If legislators were to start afresh, it would be constructed somewhat differently. Society changes and the economy changes. Even principles and their relative importance can change.

3.5  Largely because of its origins and history, the tax system today is riddled with instances where principles are in conflict. Anyone seeking to derive the principles that underpin the system today from the legislation would struggle to establish any principle from what we have on the statute book that is not contradicted somewhere in another piece of legislation.

3.6  The Committee's inquiry is potential deeply philosophical. There is a place for that; but the Announcement suggests that the Committee is more interested in the active translation of philosophy into policy than in the passive pursuit of philosophical principles for its own sake; and that is where the substance of this submission will focus.

3.7  I take the view that it is ultimately for the government of the day to determine the principles that should underpin tax policy, on the basis of a mandate, properly sought and given by the people through the election process. The principles may vary because both the wishes of the people and the economic circumstances may vary.

4.  THE INFLUENCE OF POLICY PROCESS ON POLICY OUTCOMES

4.1  I do not intend, in this short note, to comment in detail on all the questions posed by the Committee in relation to this inquiry but I should like to comment in some detail on the way in which tax policy outcomes might be influenced by changes in the policy-making process itself. Good process cannot guarantee good outcomes but it can make their achievement more likely.

4.2  I am currently engaged with others in a major project to examine, on a comparative basis, the structures, processes and governance arrangements for tax policy-making in a number of countries and the influence that the process has on policy outcomes. I should like to draw the attention of the Committee to the ongoing work on this issue and to highlight the early findings of the project that may be relevant to its inquiry, even though these are tentative at this stage.

4.3  The project is being carried out under the auspices of the Oxford University Centre for Business Taxation (OUCBT) and will provide the basis for a report for a ministerial-level meeting of the OECD.

4.4  The scope of the project is to examine:

—  the functioning of the Executive in relation to the development of tax policy, including the institutional framework within Government through which tax policy is developed;

—  the influence and role of external institutions, both formal and informal;

—  the role of the Legislature in scrutinizing tax policy proposals emanating from the Executive and the rights of the Legislature to initiate tax law changes; and

—  the process through which taxpayer consent is sought for changes in tax law, including the nature and extent of any consultation with the public or with business on tax policy proposals.

4.5  The work is being carried out mainly through face-to-face interviews with ministers, advisers, high-level officials and policy experts, other commentators, business groups and financial journalists.

4.6  The study should enable good practice to be identified in each of the four areas identified above and an initial assessment to be made of the relative significance of its contribution to good policy outcomes.

4.7  The "good practice" approach should allow Governments of both developed and developing countries to benchmark their own structures, processes and governance arrangements. It is hoped that this will, in turn, make the achievement of better policy outcomes more likely.

4.8  There is still a considerable amount of work to be done but the meetings and discussions that have taken place so far have allowed some tentative initial conclusions to be drawn.

5.  THE UK TAX POLICY-MAKING PROCESS

5.1  It may be helpful to the Committee to provide some early thoughts from the project in each of the specific areas of work.

The role of internal institutions

Concentration of power

5.2  The policy making process in the UK is highly centralised. Analysis is concentrated in the hands of the Treasury and the Chancellor's departments and all of the main decision-making process takes place within the Treasury itself. There is little involvement by other government departments although the role of BIS has, I understand, become more significant in relation to business taxation issues in recent years. Some degree of concentration is evident in the tax policy-making process in other countries but the UK is at the extreme edge among the countries examined to date.

5.3  The involvement of a wider group of Cabinet ministers in government decisions about taxation policy appears to be better established in continental Europe than in the UK. Similarly, the involvement of the Prime Minister's office in decisions on tax policy appears to be more common elsewhere.

Politically-appointed advisers and officials

5.4  Taxation is a highly technical area and ministers are rarely tax policy experts. Practice differs from country to country in relation to the appointment and use of politically-appointed ministerial advisers with specialist knowledge of taxation. In Germany, ministers do not have advisers per se within the department but the appointment of some senior tax policy officials is effectively in the gift of the Finance Minister. In France, by contrast, the Finance Minister and the Prime Minister will typically each employ advisers with a specialist tax background. The appointment of some senior officials may be considered to reflect the politics of the day. In the UK, the practice has varied over time, with mixed results.

Departmental structures and a system-wide approach

5.5  The Mirrlees Review suggests that, to be most effective, taxation policy needs to be addressed on a system-wide level. This does not negate the need for detailed work on individual taxes but the whole-system review should provide a framework within which that work is carried out.

5.6  Within the UK Treasury, taxation issues tend not to be addressed at a whole system level. This could be seen as a reflection of the departmental structure, which is organised more by themes and by individual taxes; or alternatively, the departmental structure could be seen as a reflection of an approach that puts emphasis on individual taxes and groups of taxes rather than the coherence of the system as a whole. It is difficult to be certain which is correct. The situation is nevertheless better than it was 10 years ago, in the sense that senior responsibilities are now organised across a range of taxes but there is little to encourage a true system-wide approach and an absence of senior economists with whole system responsibility. This may be considered to lead to the more piecemeal approach to tax reform in the UK.

5.7  More broadly-based reform has also been held back on a number of occasions by perceived difficulties in modelling the revenue outcomes of complex change. Fundamental tax reform will remain challenging unless outcomes can be understood and modelled with confidence.

The role of external institutions

Influence on policy development

5.8  External institutions appear to figure relatively little in the tax policy-making process in any of the countries we have examined to date. It is, of course, always a matter of debate as to whether policy is influenced by one institution or another and influence over policy may be exerted in a number of different ways. For example, although the idea for a tax change may initially come from one source that has the ear of the minister, it may be another institution whose analysis is particularly influential in shaping the development of a proposal.

5.9  In the UK, there are a number of institutions that actively seek to influence policy thinking. Some of these are think-tanks, with a point of view that reflects a broad political positioning. Others are more academic in their approach. In their respective areas of expertise, among the latter group, the Institute for Fiscal Studies and the OUCBT appear to exert some influence through the analysis that they provide.

5.10  The UK is regarded by other countries as particularly well supported by external institutions but it may be questionable how far the influence goes. In principle, governments can benefit significantly from strong external institutions in this area as in others. But a key issue in the taxation area is availability of data to those external institutions. There are issues around taxpayer confidentiality, but the value of external contributions can only be fully realised if a way is found to overcome the concerns. There has been some recent progress in this area and it is to be welcomed.

5.11  Also important to the strengthening of external contributions to the policy process would be to allow much wider publication of aggregate numbers. Researchers outside government often struggle to develop even broad estimates of the costs or revenue yield of potential tax changes and this can inhibit the development of ideas and the process of sensible debate around the tax system.

Post implementation reviews

5.12  One of the ways in which external institutions could be brought closer to the policy-making process and their formal role strengthened would be for the government to use them to carry out independent post-implementation reviews of significant changes in tax policy.

5.13  Independent reviews of this nature have not been widely used either in the UK or indeed in many countries. This is perhaps surprising because a proper process of review to establish whether a particular tax reform has met its objective can potential provide invaluable information to policy-makers, particularly on behavioural responses. But they are potentially challenging for both political leaders and civil servants. They can highlight outcomes from tax changes that are different in practice from those sought or claimed at the time of their introduction. It would nevertheless impose a good discipline on the tax policy-making process if the general practice was that the legislation that introduced substantial new measures contained a requirement for an independent post-implementation review. For certain changes, this could be coupled with a sunset clause for the measure in question.

The role of the legislature

There are features of the UK parliamentary system that tend to weaken the role of Parliament in the tax policy-making process.

Access to expert support

5.14  Members of Parliament in the UK and, in particular, members of the Standing Committee dealing with the Finance Bill have, by international standards, relatively limited access either to government officials or to other experts who might assist them in scrutinising proposals made by Treasury ministers. It is relatively common for other parliaments to call as witnesses, senior government officials and groups of experts who can respectively explain and opine on legislative proposals.

5.15  There is no professionally qualified group of officials whose role is entirely to support committee members on taxation issues. Such support is not widespread in Europe but it exists, for example, in the United States.

Powers of initiation

5.16  Powers of initiation on taxation issues do exist in theory in many parliaments but, as in the UK, there are few examples among the countries that we have investigated, where such powers are widely used. The US is the most obvious exception.

The role of the second chamber

5.17  Constitutional traditions similar to those around the House of Lords and its role in relation to taxation matters are not widely found elsewhere. The absence of an effective second chamber review or policy initiation process is a relative weakness of the UK model as it stands today.

Taxpayer consent and consultation

5.18  In most democracies, tax policy is set by the few for the many and serious policy debate is held among the few. The many are not equipped by the education system to participate effectively. Public debate through the media is frequently led by misinformation of one sort or another, whether intentionally or not.

5.19  Consultation on business taxes

5.20  There is much admiration in some countries for the way that consultation on business tax issues has become established in the UK, particularly over the last 10-15 years. There is, for example, a strong feeling in France that their tax-making process and with it, tax policy outcomes, could be enhanced significantly by greater involvement from the business community.

5.21  However, the UK is not unique in involving outside parties in consultation on tax reform. The Scandinavian countries have well-established practices of examining legislative proposals long before they are brought into law, some of them more broadly-based than our own. Other countries such as Luxembourg, have encouraged the discussion of proposals among tri-partite committees of government, employers and unions.

5.22  In the UK, individual businesses and trade and employers organisations are regular contributors to tax policy debate and their involvement in the process has had positive benefits. It has benefitted policy-makers by providing an opportunity to understand more directly than was previously the case, the impact of particular proposals on both a conceptual and a detailed level. It has also strengthened the contributing organisations by giving them a focus that goes beyond their direct work with the statute as it stands and it has given them a greater understanding of the issues and constraints on tax policy. Most important of all, it has contributed to better policy outcomes.

5.23  There is an argument that organised labour could also be encouraged more formally to participate in the tax policy-making process in the UK. This would potentially have similar benefits. As noted above, it is an established feature of some other democracies.

Democracy and tax policy

5.24  By contrast to the business taxation area, broader issues of taxation generally appear to be discussed more widely and openly in many countries than they are in the UK. There is elsewhere a greater spirit of openness about taxation policy issues in the run-up to national elections than has often been the case in the UK in recent years.

5.25  For democracy to function effectively in the UK, it would be helpful if the level of debate could be raised. A number of factors influence the current situation, including the education system, the media and the approach to political debate itself. It would be beneficial if there was a better understanding of the link between taxes and government spending. Governments of all persuasions have failed adequately to explain that, in the long term, everything that the government spends is the proceeds of taxation. It is a simple mechanism that allows government to pay for the goods and services that we accept, democratically, should be provided collectively through government rather than individually.

5.26  One of the issues that affects the taxation debate in the UK is that it tends to be somewhat remote. Taxation is essentially a national issue in the UK, whereas the decentralising of tax-raising powers makes it at least partially an issue for local or regional government as well in many other countries. The UK is highly unusual in its concentration of taxation rights at the national level. This weakens choice for citizens and may be a factor in participation levels in local government elections. It is an issue that needs to be addressed.

5.27  A fuller and more open debate with the electorate on taxation policy issues can potentially pave the way for modernising policy reforms that will be of broad benefit to the economy.
