Select Committee on Public Accounts Twenty-Third Report


3  Improving efficiency in dealing with tax returns

21. Operating the Income Tax Self Assessment filing process costs £220 million a year in staff costs or some £22 per return issued, excluding overhead costs such as IT.[59] Chasing overdue tax returns and carrying out enquiries to confirm whether the right amount of tax is being declared incurs further costs. The cost of processing an accurate paper-based return is around £13.[60] By comparison, the cost of processing benefits applications ranges from £17 for Social Fund applications to £60 for Income Support applications.[61]

22. The Department has an overall target to make efficiency savings of over £500 million and reduce staff numbers by 12,500 posts by March 2008.[62] Some 8,000 staff years are used to process self assessment tax returns and a further 1,800 staff years to chase returns and manage debt.[63] The Department processed returns at 74 offices in the UK. Two offices process around 500,000 returns, while almost half the offices handle less than 100,000 and some process only a handful (Figure 1). The Department intends to concentrate processing at about five centres by 2008 to achieve efficiency gains.[64]

23. The Department also expects to make efficiency savings of between 200-300 staff years from 2005-06 by applying more widely the practices of the more efficient offices. Further opportunities to improve efficiency arise by increasing the extent of automatic data capture from tax returns. The Department is carrying out trials to improve its processing of tax returns by introducing standardised, quicker and more accurate procedures. Although it has not yet compared the costs of processing with other taxes, it intends to benchmark cost and quality with other taxes to identify good practice.[65]

Filing returns electronically

24. The Department encourages all taxpayers to file their returns electronically. Electronic filing reduces costs both for taxpayers and the Department and improves accuracy by identifying simple errors through validation checks on the return. The Department considers the cost of processing a tax return excluding overhead costs is reduced from £22 to £13 if the return is filed electronically, by eliminating the costs of data entry and of rectifying simple errors made by taxpayers in completing the form.[66]

25. The Department has a target to obtain 35% of Self Assessment returns electronically by 2007-08, with an interim target of 25% by 2005-06. It achieved 12% in 2003-04 and met its forecast of 17% in 2004-05 -just over 1.6 million returns submitted electronically. Electronic filing in the UK is lower that in some other countries, for example the United States has achieved 44% and Australia 83%. To increase take up of online services the Department is targeting groups with high potential to file electronically through e-marketing campaigns.[67] It has offered limited incentives, such as performing the tax calculation on behalf of the taxpayer irrespective of when they file their return, to encourage self assessment filing on-line, whereas it has used financial incentives to encourage small sized businesses to file their employer returns electronically.[68] It has a mandatory regime for employers with 250 and more employees to have filed PAYE returns online.[69] The review by Lord Carter[70] of e-filing is expected to suggest ways in which the Department can increase e-filing.[71]

26. The Department acknowledges that taxpayers want a reliable service. But over the weekend of 29 and 30 January 2005, when large numbers of people were seeking to file by the 31 January deadline, the online filing service did not operate properly. Around 80,000 people did not get a message to confirm they had submitted their completed return and they were therefore unsure whether their return had been successfully filed. HM Revenue and Customs gave those affected a two week extension to file their returns. It has reviewed the problems experienced to identify the causes and prevent a recurrence. While it has increased the scale of its web-based technology, the Department cannot provide an assurance that similar problems will not occur in the future given the high number of returns that are filed on the 31 January deadline.[72]

27. There are major peaks in the workload for the Department around the two filing deadlines of September and January each year (Figure 2), which increases the Department's costs. Taxpayers are increasingly filing tax returns later each year - around 25% within two weeks of the January 31 deadline.[73] This brings a higher risk of errors in processing as the Department seeks to process these returns by the end of March so that it can take account of the information in sending out the following year's tax returns and in issuing tax codings for the start of next tax year. The Department encourages people to file by the end of September with the incentive that the taxpayer will not have to calculate the tax and if the taxpayer files on-line this facility is extended to the end of December.[74]

28. Experience of other tax authorities suggests that HM Revenue and Customs might consider more fundamental changes to the filing deadlines to reduce costs and errors. Taxpayers in the United Kingdom have 10 months to file their returns whereas overseas tax authorities typically allow taxpayers only three to four months.[75] Some tax authorities tend to collect during the year a level of tax that is likely to be higher than the final assessment and therefore taxpayers have a greater incentive to submit returns promptly to obtain the refunds owed.[76] Getting returns in earlier by bringing forward the January deadline to the autumn, or setting differential filing deadlines for different groups could smooth the peaks in workload and help to reduce errors in processing and setting tax codes.[77]

29. Sending out the returns later would also ease some of the pressure on the Department to finish processing the previous year's returns by the end of March, and the forms would also reach people when they are in a better position to complete them.[78] Lord Carter's review is considering a range of options for changing the dates when returns are sent out and the time allowed for taxpayers to return them[79] [80] and the findings of the National Audit Office's Report. The Department considers that any change in filing dates would need to reflect the differing circumstances of taxpayers, some of whom have more complicated financial affairs. It had not undertaken a cost benefit analysis of the various alternatives, but it intends to develop the management information needed for such analysis.[81]

30. Differential filing dates for paper and electronic returns are in place in ten of the 30 Organisation for Economic Co-operation and Development (OECD) member countries (Australia, Austria, Canada, France, Greece, Iceland, Ireland, Italy, Netherlands and Norway). In addition the United Kingdom has the most generous return filing dates for self calculating personal taxpayers of any OECD country. The Department has provided evidence to Lord Carter to inform his review. This outlines several options for differential filing dates such as moving the Self Assessment filing deadline from 31 January to 30 November of the preceding year; proposals for introducing a paper filing charge which would apply after a certain date while still retaining a late filing penalty; and changing the cut off date when the taxpayer does not have to calculate the tax. The Department considers that differential filing would increase the take up of online filing to 57% in the first year.[82]
