Department Name: Economics

Abstract

Good tax design and administration are central to the functioning of the economy. Taxes are important determinants of economic behaviour, and good implementation can significantly increase economic and social welfare. The role of the Tax Administration Research Centre is to deliver research that enhances tax policy and provides lasting benefit to the economy. There are many research tools that can contribute to this goal but the greatest success will be achieved by combining a range of research methodologies and disciplines.
The Centre will unite researchers from two institutions with distinguished reputations for research into tax administration and tax design. Complementary abilities and methodologies will be brought together to address a wide range of intersecting research projects. The research methodologies will include economic modelling, econometric analysis, experimentation, numerical simulation, and qualitative analysis. In undertaking its work the Centre will make extensive use of the HMRC/HMT Datalab to permit innovative empirical work to be undertaken.
Some examples of the research projects to be conducted at the Centre are:
Risk-based auditing and taxpayers' responses will investigate the reaction of taxpayers to audits, and how this will change the pattern of compliance behaviour. The project will study whether taxpayers learn about the audit strategy over time, and how a risk-based strategy should be updated to take this into account. The project will link with laboratory experiments on compliance and with research on the role of tax advisers. The results will increase the return on resources allocated to auditing.
Decomposing the elasticity of taxable income will determine how the response of individuals to taxes summarised by the "elasticity of taxable income" can be separated into the channels through which individuals respond (e.g. reduced work effort, increased pension contributions or charitable contributions, moving income abroad, taking income in other forms). The results will enable greater focus of tax interventions and improved design of tax structure.
Consequences of pre-population will study the implications of pre-populated tax returns for compliance. If the pre-populated form shows an income level below actual income this might convey an impression to the taxpayer that they can successfully evade. The research will implement an experiment that randomises the allocation of pre-populated returns. The outcome will advise on how best to proceed with the implementation of pre-population.
Large business (Intermediaries) relationship with HMRC will use qualitative depth interviews address the extent to which new initiatives have altered working practices in intermediary firms and their clients' businesses, the HMRC understanding of tax avoidance practices, and the appropriateness of current policy strategies currently. This will enhance understanding of the effects of HMRC operational policy and improve administration.
Understanding the determinants of customer experience will link HMRC survey data on customer experience with objective measures of service delivery standards, third-party information, and tax return data in Datalab. The linked data will be used to analyse the systematic determinants of subjective customer experience and will show which aspects of HMRC delivery generate a positive customer experience, and which do not.
The Centre will enhance tax administration and tax design. It has ambitious plans to become the leading international centre with a central role in research and in building research capability in tax analysis through the training of PhD students and training of research staff.

Planned Impact

The immediate impact of the Centre's activities will be an improved understanding in tax authorities in the UK and other countries of how they can enhance tax policies and administrative practices in order to better achieve the fundamental aims of the tax system. Specifically, for the UK the Centre will aid fulfilment of the aims of Parliament: to raise the desired level of revenues equitably and at least economic cost, with the minimum of administrative cost. In addition, the Centre will impact positively on the consumer experience and, through international benchmarking, drive quality improvements for tax authorities worldwide. This impact will be especially strong as the research topics for the Centre have been guided by the questions identified by the HMRC/HMT as important to their service delivery.

A further impact is that the Centre's work will benefit the international tax research community by developing a novel interdisciplinary approach to tax analysis, advancing knowledge, demonstrating innovative ways of exploiting the Datalab, training PhD students to build research capacity, and offering practical advice on the implementation of its research findings in the international context. This will generate further original research around the world to enhance tax policies and administrative practices. The academic community will benefit from membership of the Centre as International Fellows, from the visitor programme, and from participation in workshops organised by the Centre. The first international workshop is scheduled to coincide with the launch of the Centre. The Centre will also generate impact through building research capacity for the HMRC/HMT through training courses, Master Classes, and secondments.

The impact of enhanced tax policies and administrative practices will be felt in the wider community. There are clear gains to taxpayers and the economy of a tax system that is well designed and efficiently administered. Better design and administration ensure that more tax revenue is raised for given tax rates so avoiding the deleterious effects of higher rates. It also reduces the incentive for taxpayers to engage in costly tax avoidance and raises social cohesion by improving the fairness of the tax system. Improving the customer experience will also enhance the public's attitude to the tax system. These are salient impacts for public policy in the UK, and many other countries, given the current imperative to reduce large public debts and promote economic growth.

Centre members will undertake research of the highest standard that informs policy and will be published in leading academic journals. Workshops will provide opportunities for dissemination to a targeted audience. The Centre's research will also be disseminated through presentations at seminars and international conferences. The Centre will also provide user-focussed dissemination by means of reports, briefings, and presentations at HMRC/HMT. Practitioners will benefit from the training courses and Master Classes organized by the Centre. The Centre workshops will be open to practitioners from the UK and from overseas. These activities, as well as the Centre's publications aimed at tax authorities, will benefit policy by reporting the latest advances in tax research.

Description TARC has produced research along many dimensions. Key findings from a selection of projects are as follows:

Pre-population of tax returns
The experimental research of TARC has generated significant knowledge in our understanding the ways taxpayers react to the pre-population of returns that contain correct information about income or alternatively incorrect information that may lead to the over-payment or under-payment of tax. The research identified that using prompts of descriptive norms designed to increase compliance, that is messages describing the behaviour of others, were only effective when used in a dynamic manner. This has opened up a number of important questions regarding, for example, the role of technology in tax compliance. This research has informed the approach that HMRC take to the implementation of pre-population.

Avoiding errors in self-assessment
TARC has also been engaged in experimental work to understand if and how appropriate nudges and tax guidance may reduce errors among taxpayers wishing to be compliant. The design of the experiments, which was undertaken in conjunction with HMRC, examined the effectiveness of particular nudges in their ability to increase the overall level of compliance, while testing that inappropriately used nudges did not lead to a reduction in compliance. The outcomes will inform the approach that HMRC take to the design of the digital platform used in the making tax digital project as regards the amount of information taxpayers receive during the process of filling in their tax assessment. This has opened up the possibility of further collaboration with HMRC for rolling out this work in order to test the policy in a randomised control trial.

Tax Gap
TARC has been engaged in empirical work to estimate the 'income gap' (defined to be one minus the proportion of reported to true income) of the self-employed in Great Britain, an issue of particular interest for HMRC, and the evasion response of the individual characteristics of this category of taxpayers (age, marital status, and residency). The research identified ways to verifying that the income gap observed is not explained by other reasons than underreporting-and this being the innovative feature of the methodology developed. The estimates derived were in accordance with HMRC's estimates, so this work has provided a robustness confirmation to HMRC for the estimates they themselves derive. This work of TARC has also increased research capability in IAPR of Greece, as it has been adopted by the Strategic Planning Directorate of the IAPR of Greece to provide the basis for estimation of the income gap in Greece, opening up new and innovative ways of measuring the phenomenon. It has also guided (through the work of a TARC-PhD who secured a placement there) the recent attempt of the New Zealand Inland Revenue to estimate the 'income gap'.

Long run effects of audits
TARC has been engaged in empirical work, in conjunction with HMRC, to estimate (using data from HMRC's random audit programme) how long lasting are tax audits and how the behaviour of taxpayers changes after such an event. This has opened up new research questions related to how the long-run effects of audits interact with the social network of audited taxpayers. Understanding such mechanism provides valuable information to HMRC regarding their optimal audit strategy.

Large Business Advisors
An interview based study canvassing opinions of tax advisors to large businesses from a range of backgrounds regarding recent developments in the relationship with HMRC. The project finds that the market for tax advice for large business taxpayers is complex and dynamic, responding to recent initiatives designed to curtail the incidence of tax avoidance .
A qualitative study of how people talk about tax and compliance obligations in social media finds that most participants are not concerned with finding ways to avoid paying taxes, but rather are wanting to comply with their tax obligations and find it difficult to find out the correct procedures. There is evidence of social pressure, especially in relation to newcomers to the tax regime.

Taxpayer Compliance
A project looking at the tax gap and has produced some interesting findings using ONS data that are being used by HMRC. The research investigated the extent of income underreporting by the self-employed in Great Britain for the period 2010-12 and the characteristics of the individuals most associated with non-compliance with the aim of answering not only 'How Much' but also 'Who'. It found that self-employment income is underreported on average by 19.3%, which translates into a lower bound estimate of unreported taxable income of 1.6% of GDP.

The researchers further investigated which characteristics of the individuals are mostly associated to noncompliance using not only characteristics that typically appear on tax returns but also a wider range of socioeconomic characteristics ('Who?'). They found that men are less compliant than women and that individuals become more compliant as they age. Regarding occupations, blue-collar households seem to underreport more than white-collar. Self-employed operating in partnerships are found to underreport more than own account self-employed and the presence of more than one self-employed in the household seems to give more opportunity to evade.
Overall, this study responds to a need for a reassessment of the extent of income underreporting by the self-employed as it is becoming an increasingly common occupational choice in the UK. The findings of this study are useful to inform the revenue agency about the individuals to whom compliance activities should be directed in order to increase their impact given that resources are limited.

A further project investigated the dynamic effects of tax audits on income reported in subsequent tax returns. Results suggest that audits lead to a modest increase in survival in self assessment for two years after the audit, peaking at 1.1 percentage points in year two before falling back. This pattern is consistent with individuals being more diligent in filing their tax returns while audit investigations are ongoing. For reported total taxable income, we find a statistically significant increase of £795 two years after audit. Increases in subsequent years are not significant but are still substantial at around £500 until at least the sixth year after audit. For total tax, the point estimates are all positive but are not significant.
Exploitation Route TARC has taken the findings forward through direct interactions with HMRC, the tax authority community in the UK and other stakeholders, such as the Tax Administration Diagnostic Tool (TADAT), International Monetary Fund, World Bank, Organisation for Economic Co-operation and Development (OECD), tax authorities including the Independent Authority of Public Revenue of Greece, Bulgarian National Revenue Authority, New Zealand Inland Revenue.

TARC has engaged intensively with beneficiaries, most notably HMRC, which has had input to some extent in all existing research projects and with which several research projects have been explicitly co-developed. It has also engaged extensively with IAPR of Greece.

Description The research at TARC is funded jointly be the ESRC and by HMRC/HMT. There is a close working relationship between TARC and HMRC. Each project is assigned key contacts within Knowledge and Intelligence (KAI) at HMRC and further linked with stakeholders within HMRC. The research design requires that the TARC projects have benefit for the stakeholders within HMRC. The research outputs have fed back to inform the operations of the stakeholders. Two projects illustrate this work. TARC has been engaged in experiment work to determine the reaction of taxpayers to pre-population of tax returns. The intention of HMRC is to digitize all operations and to move to pre-population. The research of TARC has revealed the ways in which taxpayers react to pre-population returns that have information missing on some sources of income or incorrect pre-populated information. This research will inform the approach that HMRC take to the implementation of pre-population. A second TARC project has considered the effect of tax amnesties to encourage the declaration of income held abroad. This work has been presented at HMRC to very interested audiences and will be an input into the design of future amnesty projects. The TARC projects are informed by policy issues and pursued in close collaboration with HMRC. We are also pursuing public engagement activities informed by the work TARC pursues.

Impact TARC has committed to provide a programme of masterclasses that will benefit both academics and tax administrators. The first masterclass was held in November. The class was given by Brian Erard who has published on tax compliance and has extensive consulting experience with US Internal Revenue Service. The target was to attract 20 participants to the masterclass. This was considerably exceeded and eventually 39 participants registered. Over 70 percent of the participants were tax administrators, (including representatives from the Australian Tax Office, Canada Revenue Service, Danish Customs and Tax Administration, HMRC, and the Italian Revenue Agency. The academics participants were from the UK and Germany. The class was focussed on the measurement of the tax gap. HMRC have a formal duty to report an annual measure of the tax gap and are continually seeking to improve the measure. Brian Erard has provided advice to the IRS on statistical methods to improve measurement of the tax gap. The participants valued this experience and the satisfaction ratings submitted at the end of the masterclass were excellent. The masterclass was a perfect knowledge exchange activity with two days of active discussion and interaction.

PI Contribution Behavioural Compatibility between Individual Choice and Collective Action TARC has developed considerable expertise in applying agent-based modeling to investigate audit strategies. The simulations in Hashimzade et al. (2013, 2014a, 2014b) base the modeling of individual agents on recent advances in behavioural economics. The agents make choices under risk with non-expected utility preferences, learn attitudes and beliefs from interaction in a social network, and make decisions taking into account the social environment in which they are located. The methods underlying this work can be extended and modified to address a much broader set of policy questions. TARC also has specialized capabilities in experimental economics. It has ready access to a large body of student experimental subjects. More importantly, it has pioneered the use of online experiments in collaboration with market research companies to target specific sectors of the population. The results in Fonseca et al. (2015) demonstrate the value of using online experiments to access a subject pool of the self-employed, whose experimental behaviour is significantly different from that of the student population. TARC also provides competence at econometric analysis and the analysis of large datasets. Advani et al. (2015) demonstrates how a question that has long been debated - the effect on future compliance of an audit - can be answered by applying imaginative empirical techniques to administrative data
Collaborator Contribution IQTE is one of most important departments in CASS and acts as a "think tank" for supporting state decisions on fiscal (tax) and financial policy-making. It is highly skilled in studying realistic economic problems using mathematical and interdisciplinary analysis and other relevant methods. There are some research areas such as agent-based modeling (ABM), experimental economics, and game theory that have risen to prominence in IQTE in recent years. The application of these methods has been focused on economic development and social welfare enhancement. Cai (2015) exploited big data techniques to show how to understand the effect of micro-behavioural characteristics on macro outcomes, Dong (2014) analyzed the behaviour of trans-national investors to explain outcomes in international financial and capital markets, Wang (2012, 2014) explored income gap evolution and public services in China using experimental methods incorporating human subjects and computational agents with support from the NSFC. IQTE intends to develop further capabilities in behavioral analysis and wishes to pay increasing attention to understanding macro outcomes through deeper analysis of micro behavior. The understanding of the behavioral compatibility between individual choice and collective action will be applied to policy issues confronting the Chinese economy.
Impact The respective capabilities of IQTE and TARC provide a very promising foundation upon which to establish an international partnership. There is a strong overlap of expertise in research methodologies and a commonality in the wish to apply frontier research methods to practical policy problems.

PI Contribution TITLE: Estimating risk-based audit rules The project develops from TARC01. That project was concerned with audit rules in a theoretical model. This project uses self-assessment data and audit data located in Datalab to estimate the factors determining the compliance behaviour of individuals and the outcome of audits. The results so far have been derived using data for 2010. The cross-sectional study of UK tax non-compliance has been extended for 6 years (2005-2010). The econometric output is robust for each year and confirms previous findings in literature. For each year all four types of taxpayers including "Individual", "Company", "Partnership", and "Trust" are included in the analysis. In addition, more observations for each type have been included in our calculations to detect omitted income tax. The recent work has estimated a Probit equation to determine the probability of audit as a function of tax return information. The estimated probability will be used as control variable in the compliance estimation equation.

PI Contribution TITLE: Analysing individuals' use of tax relief for pension contributions To develop an understanding of what determines individuals' private pension contribution decisions that will assist in government policy making. This was done by analysing the change in pension contributions that arose as a result of the change in the income tax law to phase out the personal allowance for taxpayers with adjusted net income above £100,000. The resulting estimates were used to develop a model of decision-making behaviour that can be used to better understand the likely impact of changes in pension rules (such as limits on pension accrual) and tax rate changes on individuals' income tax liabilities and on the size of their pension contributions.

PI Contribution Title: Voluntary Disclosure Schemes for Offshore Tax Evasion: An Analysis In recent years tax authorities worldwide have implemented voluntary disclosure schemes to recover tax on offshore investments. Such Schemes are characterized by the acquisition of non-audit information on offshore holdings, and a subsequent opportunity for affected taxpayers to make a voluntary disclosure. Accepted disclosures are subject to a discounted fine rate, but verified under-disclosure attracts a higher penalty. We characterize the optimal Scheme and show that an optimal Scheme can generate a Pareto improvement over the optimal auditing equilibrium without a Scheme, and can stimulate legitimate offshore investment activity. We show when a tax authority optimally gives incentives for honesty, and when it does not. The analysis yields practical design insights for HMRC practitioners.

The working hypothesis is that the model of HMRC cannot be extended to include a credible description of financial transactions whilst retaining the current solution process and modelling language.

PI Contribution Title: Laboratory experiment on pre-population TARC 21 was undertaken to conduct a series of experiments testing (1) the impact of pre-populating tax returns on compliance behaviour; (2) the impact of behavioural prompts on compliance. We report on data from an artefactual field experiment on the effect of pre-populating tax forms with third-party data, as well as using behavioural prompts designed to increase compliance. We use a sample of UK taxpayers as our subject pool. The main results were: (i) the correct pre-population of values in tax forms has no effect on compliance; (ii) the incorrect pre-population of income values in the tax form reduces compliance; (iii) the introduction of barriers to editing pre-populated fields may worsen non-compliance if the pre-populated values are incorrect; (iv) behavioural prompts concerning descriptive norms of compliance can mitigate the negative impact of incorrect pre-population of tax returns only if they are responsive to behaviour in the filing process; finally (v) a proportion of subjects overpaid taxes when the tax form was populated with a value above the true income.
Collaborator Contribution HMRC actively participated in the co-designing of the experimental environment and treatments, using not only insights from their operational teams, but also having in mind policy priorities.

PI Contribution The aim of this project is to understand what effect reforms to capital gains tax (CGT) have on realisations of capital gains. From a policy perspective, this is important to know, since it will help with the design of future reforms. There have been a number of important reforms to capital gains tax (CGT) over recent years, many of which have provoked significant interest and reaction from the public and businesses. In April 2008, a single CGT rate of 18% was introduced (except for certain assets eligible for entrepreneurs' relief, taxed at 10%). In June 2010, the CGT rate for assets not under entrepreneurs' relief was raised from 18% to 28% for higher-rate income tax payers.
Collaborator Contribution HMRC have provided feedback to TARC researchers
Impact We conducted an assessment of the feasibility of estimating the impact of reforms to capital gains tax (CGT) on realisations of capital gains. We concluded that the data was not of sufficient quality to enable work to continue. Specifically: • To analyse the 2008 CGT reform, we need to be able to identify what assets (would) qualify for taper relief and for entrepreneur's relief both before and after the reform. This is not possible: all we observe is broad asset class (which doesn't pin down entitlement to taper relief and entrepreneur's relief) • For the 2010 reform, the idea was to compare realisations of non-qualifying assets for higher-rate taxpayers (for which the tax rate increased from 18% to 28%) against a group that was not affected by the reform (e.g. realisations of non-qualifying assets for basic-rate taxpayers). For this we need to use the detailed asset-level CGT data, which is only available for a small subset of individuals declaring capital gains on their self-assessment returns. Unfortunately the number of observations in treatment and control groups was not large enough to be able to make reliable comparisons.

In the first study we manipulate the extent to which different quality levels of service provision in the experiment lead to different levels of non-compliance. From the first study, we aim to identify the potential channels through which service quality affects non-compliance. And we hypothesize that one of the most important channels may be the psychological/emotional state of the customer. In the second study, we exogenously vary subjects' psychological states and estimate the effect of those different psychological states have on honesty over and above standard economic explanations for non-compliance.

PI Contribution Title: Is there a positive compliance impact of sending nudges to HMRC's customers? The objective of any national tax administration is to collect the correct amount of tax owed by taxpayers. Doing so means minimising the degree of non-compliance by taxpayers, either due to evasion or genuine error. To this end, in autumn 2015 the UK Government announced the introduction of online digital tax accounts. A modern tax system, based on digital technology will make it easier for businesses to get their tax right. Reducing the amount of avoidable errors will also reduce the cost, uncertainty and worry that businesses face when HMRC is forced to intervene to put things right. The logic of digitising the tax system is widely recognised and millions of businesses are already banking, paying bills, and interacting online. The next step is to digitise routine business tasks such as record keeping; many businesses have already done so. The new digital system allows HMRC to employ an array of behavioural nudges to help taxpayer's get things right and reduce common errors. The research project aims to answer the following three questions: - Do nudges improve compliance/elicit a change? - Do taxpayers ignore the nudges? If so, why? - How much time do taxpayers spend reviewing the nudge and making changes to their data? This project is a test of the effectiveness of particular forms of nudges on behaviour and their mode of delivery in terms of helping taxpayers get things right and reducing common errors. It is done in tandem with the development of the actual Making Tax Digital for Business (MTDfB) delivery system used by HMRC, and therefore of great benefit to tax administration. The research will determine the effectiveness of our delivery of nudges through software and identify further opportunities to improve upstream compliance measures.
Collaborator Contribution HMRC actively participated in the co-designing of the experimental environment and treatments, using not only insights from their operational teams, but also having in mind policy priorities.

PI Contribution Project Title: Role of Intermediaries in the relationship of large business customers with HMRC Descriptive Summary: In order to better understand the market for tax advice in the context of large business (in the first instance) the research aims to: • Map the field of intermediaries to obtain a clearer picture of the types of intermediaries, the particular services they offer and to which type of client. • Determine how intermediaries have changed or modified advice to clients in response to recent developments such as DoTAs, CRMs, SAO. • Obtain a clearer understanding of how tax intermediaries 'translate' the tax code, and changes therein, into advice to clients. The project is interview based: all interviews completed as at December 2015. The project overlaps with work being done under the Horizon 2020 EU funded project "FairTax" (http://www.fair-tax.eu) for which a new round of interview fieldwork is currently underway
Collaborator Contribution HMRC analysts provided suggestions regarding topics of interest to be explored during the fieldwork data collection. A meeting with operational staff from the Large Business Unit to discuss the final report has informed the analysis and development of scholarly publication (in progress).

Description TARC Project 8 led by Miguel Fonseca 
Organisation HMRC HM Revenue & Customs
Country United Kingdom 
Sector Public 
PI Contribution TITLE: Understanding the Determinants of Customer Experience HMRC offers a wide variety customer services and the level of contact to which customers are exposed to these will vary considerably. Across these services there are a variety of factors which may impact on customers' perceptions of them. In turn, the customers' experiences could affect their behaviour in a number of different ways, ranging from increases in avoidable error through to deliberate evasion. The two behavioural responses under scrutiny will be (i) the extent to which participants comply (note that we may not be able to distinguish errors from deliberate non-compliance), and (ii) the timeliness with which participants file their return.
Collaborator Contribution HMRC have provided feedback to TARC researchers
Impact This project was withdrawn due to it not being a high-priority area within HMRC. Preliminary work on this project informed the experimental work on pre-population. The preliminary work has also been used to inform a project on customer satisfaction that is being conducted under contract to the NAO.

Results and Impact Lynne Oats presented ' What Makes Tax Collection Sustainable?' at a dissemination event in at the Swedish Representation in Brussels for the FairTax EU funded project that links to TARC 7.

In the final presentation, Karen Boll, Copenhagen Business School and Lynne Oats, Exeter University presented their research on the topic "What makes Tax Collection Sustainable?". The researchers pointed out that the administrative dimension of tax policy implementation is crucial to its success. Using the case of large businesses, cooperative relationships between taxpayers and tax authorities are being examined in several countries to identify features leading to sustainability and barriers to success.

The discussant for this session, Hans Gribnau, Tilburg University, responded to the presentation and noted that willingness of the taxpayers to comply with taxes is at the heart of cooperative compliance. There is a common interest between the tax administration and the taxpayer in getting a clear, certain result. Mutual trust is an important element in the success of cooperative arrangements.

The presentation was followed by a question and answer session, during which some very interesting and thought provoking questions were put to both the presenters and discussants.
