IRS’s 2008 budget request proposes to increase spending. The $11.6 billion requested total operating budget is an increase of $608.8 million (almost 5 percent) over the FY 2007 level as shown in table 1. IRS proposes to fund 92,814 full-time equivalents (FTE), a slight decrease compared to the FY 2007 level. Table 1 summarizes IRS’s appropriation accounts and shows that its 2008 budget submission continues a trend of shifting spending toward enforcement. The request for $4.9 billion for direct enforcement appropriations is an increase of 3.9 percent over the FY 2007 level and almost 4.6 percent over the FY 2006 level. Table 1 also shows that IRS is requesting more funding for operational support in 2008 over the 2007 level. Among the reasons for the increased spending is that IRS is proposing to reduce the backlog of outdated information systems and telecommunications equipment. Finally, IRS is requesting $282 million for its BSM program—a significant increase in funding over both FYs 2006 and 2007. This includes over $55 million for developing and deploying the capability to accept individual income tax returns on Modernized e-File and $16 million for new Web portals to support key business processes and compliance initiatives. When operational support funding shown in table 1 is allocated to enforcement and taxpayer service, a more complete picture of what IRS actually spends on these activities emerges. Based on the allocation reported in the budget request, IRS plans to spend a total of $7.2 billion for enforcement and $3.6 billion for taxpayer service. Including operational support, IRS is requesting almost 56,600 FTEs for enforcement and about 35,200 FTEs for taxpayer service (an increase of 0.7 percent and a decrease of 3.7 percent, respectively, compared to FY 2007 levels). Figure 1 shows that this continues a trend since 2004 of shifting a greater portion of spending toward enforcement as compared to service. In years following passage of the IRS Restructuring and Reform Act of 1998, IRS made significant progress in taxpayer service, although there were declines in many aspects of enforcement activities, such as for enforcement staff and revenue collected as shown in figures 2 and 3, respectively, later in this statement. However, at FY 2008 requested levels, total spending for enforcement will increase by over 19 percent while spending for taxpayer service will decrease by almost 4 percent since 2004. In the 2008 budget submission, IRS proposes a number of new initiatives, all of which are intended to improve taxpayer compliance—some by increasing staffing for enforcement or making legislative changes, and some by improving taxpayer service or infrastructure. The request includes estimates of the annual costs of the initiatives plus, for some initiatives, dollar estimates of the increased revenue expected to be realized, as summarized in table 2. IRS recognizes that there are likely revenue effects beyond those shown in table 2. Table 2 shows, for example, the direct revenue from new enforcement initiatives. Direct revenue is the amount collected from taxpayers targeted by IRS enforcement actions, such as audits. However, the budget submission states that enforcement actions have indirect revenue effects as well by increasing voluntary compliance by all taxpayers. The magnitude of the indirect effects of enforcement is not known with a high level of confidence because of challenges in measuring compliance; developing reasonable assumptions about taxpayer behavior; and accounting for factors outside of IRS’s actions that can affect taxpayer compliance, such as changes in tax law. However, several research studies have offered insights to help better understand the indirect effects of IRS enforcement on voluntary tax compliance and show that they could exceed the direct effect of revenue obtained. Given the uncertainty of estimates of indirect revenue, in its budget request, IRS says that it cannot measure the impact of deterrence of enforcement or service on compliance, but only that their effects are positive. Finally, the budget request also recognizes that the initiatives intended to improve taxpayer service or modernize information systems are also expected to ultimately improve taxpayer compliance. Again, however, reliable information about the magnitude of the improvement is not available. Over the 3 years shown in table 2, IRS expects the estimated cost for the initiatives will decrease while the resulting direct revenue increases. IRS is requesting about $410 million for FY 2008 to fund all the initiatives, with the estimated costs declining in FYs 2009 and 2010 because of start-up costs in FY 2008. IRS is projecting that direct revenues will increase by about $2.6 billion in FY 2010, as more staff are hired, trained, and become more productive, and all aspects of the legislative initiatives are phased-in, particularly for the information reporting requirements. However, the direct revenues expected are small compared to the estimated $290 billion net tax gap for tax year 2001. For instance, the revenue-producing initiatives are expected to yield about $699 million in FY 2010, or about one-fourth of 1 percent of the tax year 2001 net tax gap. In 2010, the total estimated increased revenue from both the revenue-producing and legislative initiatives, about $2.6 billion, is about 0.9 percent of the 2001 net tax gap. No single approach, such as IRS enforcement, is likely to fully and effectively address noncompliance. Multiple approaches are needed because noncompliance has multiple causes and spans different types of taxes and taxpayers. Approaches include devoting additional resources to enforcement, providing more enforcement tools like information reporting, improving taxpayer service, periodically measuring compliance, setting tax gap reduction goals, leveraging technology to enhance IRS’s efficiency, and simplifying or reforming the tax code. For example, regarding information reporting, we recently recommended to IRS, that to assist taxpayers in accurately reporting their capital gains and losses from securities, in the instructions to Schedule D clarify the appropriate use of capital losses to offset capital gains or other income and provide guidance on resources available to taxpayers to determine their basis. Justifications for the new spending initiatives varied in the basic information they provided. In some cases, the budget submission lacked information that would have allowed us or others to assess the proposed spending and comment on, for example, whether the initiative would be a worthwhile expenditure in light of expected benefits and costs. To better understand IRS’s initiatives and their expected benefits and costs, we asked for supplementary documentation on selected new spending initiatives: Improve compliance among small businesses and self-employed (SB/SE) taxpayers: $73.2 million; 485 FTEs Critical upgrades to IT infrastructure: $60 million; 0 FTEs Improve tax gap estimates, measures, and noncompliance detection: $41.0 million; 258 FTEs Improve compliance for large multinational businesses: $26.2 million; 158 FTEs Research effects of taxpayer service on compliance: $5.0 million; 8 FTEs Expand volunteer income tax assistance (VITA): $5.0 million; 46 FTEs Our review of the justifications showed that some had descriptive, cost, and expected performance information while others lacked such information. Our previous work on results-oriented government and performance budgeting, states that budget requests and supporting documentation should provide information on the results to be achieved with the funding requested. More specifically, our work has shown that congressional decision makers benefit from information on the problem or performance shortfall to be addressed, cost estimates, and performance measures and goals. The justification for the initiative to upgrade IT infrastructure included information on the extent of the problem, including the impact of computer downtime on employee performance and how much IRS’s aged computer inventory would grow without additional funding. Similarly, the initiatives to increase compliance among SB/SE taxpayers and large multinational businesses had such information as the portion of the tax gap that is attributable to certain types of taxpayers, data on growth in certain tax return filings for businesses that are high-risk for underreporting, and the need for increasing enforcement activity in these areas. However, the justification for expanding VITA did not provide problem or performance shortfall information, such as evidence of how some taxpayers do not receive needed services due to the current level of spending or problems with those taxpayers’ compliance levels due to the lack of services. Similarly, the initiative to research the effects of taxpayer service on compliance did not explain the problem such research would correct. The IT initiative had information on the planned expenditures to upgrade specific computer equipment, including descriptions of the equipment and how it is to be used. Also, the initiatives to increase compliance among SB/SE taxpayers and large multinational businesses had descriptions of the types of staff to be hired and work to be done—such as examinations, collections, and legal support. However, the justifications for the initiatives to improve tax gap estimates and expand VITA lacked information on how IRS determined the amount requested or FTEs needed. We could not determine the budget or FTEs or specifics about the work to be done such as the number of examinations to be conducted. Further, the initiative to research the impact of service on compliance lacked descriptive details on the work to be done—such as potential research questions, methodologies, deliverables, and estimated costs of delivering them—that would provide examples of what IRS would accomplish with proposed spending and allow Congress or others to assess the initiative. The compliance initiatives had performance measures and goals, such as direct revenue to be generated or additional examinations to be conducted; the IT initiative had quantitative targets for reducing the aged computer inventory; the VITA initiative had a target for improving the quality of returns prepared by volunteers; and the tax gap estimate improvement initiative had quantitative targets related to examinations. However, the initiatives for researching the impact of service on compliance lacked a performance measure and target, such as, for improving the use of IRS resources based on the research. We do not contend that because some of the justifications were lacking in certain information that the initiatives are not worthwhile, or that all justifications should have the same extent and types of information. For example, although the justifications for conducting research to improve tax gap estimates and determine the effects of taxpayer service on compliance lacked certain information, in previous reports and testimony we have been supportive, in general, of such research. However, without some explanation of how cost and resource needs were determined for these initiatives, assessments of whether the initiatives are worth their costs are not possible. Since gathering basic information to justify an initiative has costs, it is reasonable for justifications of more costly initiatives to have more detail. When all the basic information becomes too cumbersome to include in the budget submission itself, an agency can supplement its request with readily available supporting documentation. In its 2008 budget request, IRS identified $120 million in savings as it has done in prior years—$82.3 million through enhancing technology and streamlining work processes in its enforcement programs and $37.7 million through increases in electronic filing from its taxpayer service programs. IRS is proposing to use all internally generated savings to maintain its current operating levels. In addition to the areas identified by IRS in its budget request, there are additional opportunities for savings and efficiency gains. Increasing electronic filing through mandates: Last year we reported that state mandates that required paid preparers who file a certain number of tax returns to electronically file state tax returns increased federal electronic filing. Without a federal mandate, IRS is missing an opportunity for savings—using IRS’s estimate that it saves $2.38 on every return that is processed electronically we estimated that IRS would save $68 million per year if 90 percent of returns submitted by preparers that are currently filed on paper were filed electronically. However, IRS lacks the authority to mandate electronic filing for paid preparers and we suggested to Congress that it mandate filing by paid preparers meeting criteria, such as filing a certain number of tax returns. Consolidating telephone call sites: We previously reported that IRS has excess space at its call site operations and the agency had a study underway to determine the feasibility of consolidating those operations. IRS has nearly completed the first phase of the study and plans to complete the second phase in 2008. According to IRS officials, this study is on schedule and is important because it will allow IRS to identify the costs and benefits of consolidating phone operations. Consolidating or retiring legacy systems: We have previously recommended that IRS prepare a long-term vision and strategy for completing the BSM program, including establishing time frames for consolidating and retiring legacy systems. While IRS developed an initial modernization vision and strategy and associated 5-year plan, more remains to be done for IRS to fully address our recommendation. Consolidating and retiring legacy systems should lead to a reduction in costs associated with maintaining these systems. Changing the menu of taxpayer services: IRS recently issued its comprehensive strategy for improving taxpayer service, including for telephone, walk-in, volunteer and Web site assistance. That strategy, known as TAB, was developed in response to a congressional directive. In addition to providing information on taxpayer needs of service, TAB provides information on the cost of taxpayer serviced for the various types of service. Information on needs and costs, along with a better understanding of taxpayer’s preferences, needs and expectations, could provide taxpayers with the same taxpayer service benefits at a lower cost through alternative methods. IRS has made noticeable progress in its enforcement efforts including increasing the amount of direct enforcement revenue collected, number of collection activities undertaken, and enforcement staff. Nevertheless, enforcement of the tax laws remains high risk, because of the persistence of the tax gap and the lack of a data-based plan. IRS reported that direct enforcement revenue rose from $43.1 billion in FY 2004 to $48.7 billion in FY 2006 (a 13 percent increase). As shown in figure 2, most of the enforcement revenue is from IRS’s collection efforts ($27.5 billion), followed by examination ($17.4 billion) and document matching ($3.2 billion). In recent testimony, the IRS Commissioner reported increases in some enforcement activities; for example, he reported that the overall percentage of individual income tax returns examined between FYs 2001 and 2006 increased by about 75 percent. IRS’s 2008 budget request shows that enforcement goals are comparable or slightly greater than 2006 actual performance and 2007 planned performance; for example, the examination rate of all individual income tax returns will remain at 1 percent. Also, IRS is proposing to increase document matching activities for individual taxpayers and increase examinations for businesses. With its 2008 budget, IRS is proposing to roughly maintain its skilled enforcement staff at the FY 2006 level—just over 21,000 FTEs. This would be an increase of over 8 percent since its low in FY 2003, as shown in figure 3. However, it is 9 percent less than the skilled enforcement staff that IRS had in FY 1998. IRS has three main categories of skilled enforcement staff: revenue officers, who perform field collection work; revenue agents, who examine complex returns; and special agents, who perform criminal investigations. Despite the projections for skilled enforcement staffing, officials from the SB/SE and Large and Mid-Size (LMSB) divisions noted that even maintaining skilled enforcement staff levels may be difficult because both divisions are experiencing high attrition rates because of retirements. Furthermore, officials said the 2007 continuing resolution limited their ability to hire in 2007. SB/SE and LMSB officials noted that the delays in hiring may have an adverse affect on their ability to meet performance goals in 2008 and beyond, particularly for the most complex examination issues, including abusive tax shelters and corporate returns, because of the lead time needed to train and develop staff. Recently, IRS studied individual taxpayer compliance through the NRP, and used the resulting compliance data to estimate the tax gap for individual income tax underreporting and the portion of employment tax underreporting attributed to self-employment taxes for tax year 2001. NRP, which involved reviewing around 46,000 individual tax returns, has yielded new information on taxpayer compliance for the first time since IRS’s previous compliance measurement study was undertaken for tax year 1988. As a result of NRP, IRS has taken steps to better ensure efficient allocation and use of its enforcement resources. For example, the NRP study has provided better data on which taxpayers are most likely to be noncompliant. IRS is using the data to improve its audit selection processes in hopes of reducing the number of audits that result in no change, which should reduce the unnecessary burden on compliant taxpayers and increase enforcement staff productivity. Despite the progress in enforcement, enforcement of the tax laws remains on our high risk list because of the persistence of the tax gap and, among other things, the lack of a data-based plan to address it. The tax gap has been a persistent problem in spite of a myriad of congressional and IRS efforts to reduce it, as the rate at which taxpayers voluntarily comply with our tax laws has changed little over the past three decades. The rate at which taxpayers pay their taxes voluntarily and on time has tended to range from around 81 percent to around 84 percent. IRS’s most recent estimates of the gross tax gap are $345 billion for tax year 2001, and the net tax gap is estimated to be $290 billion. IRS’s overall approach to reducing the tax gap consists of enhancing enforcement and improving taxpayer service. IRS uses its enforcement authority to ensure that taxpayers are reporting and paying the proper amounts of taxes through efforts such as examining tax returns and document matching. IRS seeks to improve voluntary compliance through efforts such as education and outreach programs and tax form simplification. IRS needs better, more continuous compliance research and better measurements of compliance. We have long been a supporter of such research, because it can give IRS and Congress an important measure of taxpayer compliance and it allows IRS to better target enforcement resources towards noncompliant taxpayers. Taxpayers benefit as well, because properly targeted audits mean fewer audits of compliant taxpayers and more confidence by all taxpayers that others are paying their fair share. IRS’s budget request includes $41 million for improving tax gap estimates and detecting noncompliance including for a rolling NRP sample of individual taxpayers and a dedicated cadre of examiners to conduct audits. Using a rolling sample, IRS plans to replicate the 2001 NRP study by conducting audits of a smaller sample size instead of larger intermittent efforts. At the end of 5 years, IRS would have a comparable set of results to the 2001 study and continue to update the study annually by sampling the same number of taxpayers, dropping off the oldest year in the sample, and adding the new years’ results every year. While we have concerns about the lack of basic information to justify the specific funding requested, we generally support this approach. We have previously reported that doing compliance studies once every few years does not give IRS or others information about what is happening in the intervening years, and a rolling sample should reduce costs by eliminating the need to plan entirely new studies every few years or more and train examiners to carry them out. IRS also needs a data-based plan to reduce the tax gap. Congress has been encouraging IRS to develop an overall tax gap reduction plan or strategy that could include a mix of approaches like simplifying code provisions, increased enforcement, and reconsidering the level of resources devoted to enforcement. Some progress has been made toward laying out the broad elements of a plan or strategy for reducing the tax gap. On September 26, 2006, the U.S. Department of the Treasury, Office of Tax Policy, released “A Comprehensive Strategy for Reducing the Tax Gap.” However, the document generally does not identify specific steps that Treasury and IRS will undertake to reduce the tax gap, the related time frames for such steps, or explanations of how much the tax gap would be reduced. In a recent hearing, the Chairman of the Senate Finance Committee asked the Secretary of the Treasury for a more detailed plan by July 2007. IRS’s key filing season efforts are processing electronic and paper individual income tax returns and issuing refunds, as well as providing assistance or services to taxpayers. As already noted, processing and assistance were complicated this year by three tax system changes: TETR, the split refund option, and enactment in December 2006 of tax law changes. From January 1 through April 20, 2007, IRS processed approximately 104.6 million individual income tax returns, about the same number as last year, and issued 88.2 million refunds for $203 billion compared to 85.2 million refunds for $190.5 billion at the same time last year. Over 65 percent of all refunds were directly deposited into taxpayers’ accounts, up 3.5 percent over the same time last year. Direct deposits are faster and more convenient for taxpayers than mailing paper checks. IRS recently granted some extensions to taxpayers, including those affected by a major storm and those unable to file their returns because of a software company’s server problems. According to IRS data and officials, performance is comparable to last year. IRS is meeting most of its performance goals, including deposit error rate, which is the percentage of deposits applied in error, such as being posted to the wrong tax year. Groups and organizations we spoke with, including the National Association of Enrolled Agents, the American Institute of Certified Public Accountants, and large tax preparation and tax preparation software companies, corroborated IRS’s view that filing season performance is comparable to last year. IRS uses two systems for posting taxpayer account information—the antiquated Master File legacy system and CADE. The latest release of CADE became operational in early March, 2 months behind schedule because of problems identified during testing. IRS originally planned to post 33 million taxpayer returns by CADE, more than four times the 7.4 million posted by CADE last year. We reported in early April that IRS had revised this estimate down to approximately 17-19 million taxpayer returns. However, as of April 20, IRS has posted fewer tax returns than expected—9.1 million—with the remainder being posted to the Master File legacy system. This means that millions of taxpayers did not benefit from faster CADE processing this year. Taxpayers eligible for a refund this year whose returns are posted by CADE will benefit from CADE’s faster processing, receiving their refunds 1-5 days faster for direct deposit and 4- 8 days faster for paper checks than if their return had been processed on the legacy system. The CADE setback may impact IRS’s ability to deliver the expanded functionality of future versions of CADE, thus delaying the transition to the new processing system (discussed further in the BSM section of this testimony). The rate of electronic filing is up compared to the same period last year. As of April 20, over 72.6 percent of all individual income tax returns (75.9 million) were filed electronically, up 8.5 percent over the same time last year. We previously reported that state mandates for electronic filing of state tax returns also encourage electronic filing of both state and federal tax returns, and last year, we suggested that Congress consider mandating electronic filing by paid tax preparers meeting criteria, such as a threshold for number of returns filed. Last year, electronic filing of federal returns increased 27 percent for the three states (New York, Connecticut and Utah) with new 2006 mandates. This year, state mandates are likely to continue to show a positive effect on federal electronic filing because, with the addition of West Virginia, 13 states now have state mandates. Compared to processing paper returns, electronic filing reduces IRS’s costs by reducing staff devoted to processing. In 2006, IRS used almost 1,700 (36 percent) fewer staff years for processing tax returns than in 1999, as shown in figure 4. IRS estimates this saved the agency $78 million in salary, benefits, and overtime in 2006. Electronic filing also improves service to taxpayers. Returns are more accurate because of built-in computer checks and reduced transcription errors (paper returns must be transcribed in IRS’s computers—a process that inevitably introduces errors). Electronic filing also provides faster refunds. Although electronic filing continues to grow, taxpayers’ use of the Free File program continues to decline. The Free File program, accessible through IRS’s Web site, is an alliance of companies that have an agreement with IRS to provide free on-line tax preparation and electronic filing on their Web sites for taxpayers below an adjusted gross income ceiling of $52,000 in 2007. About 95 million (70 percent) of all taxpayers are eligible for free file. Under the agreement, companies are not allowed to offer refund anticipation loans and checks, or other ancillary products, to free file participants. Although IRS has increased its marketing efforts, the agency has not been successful in increasing free file use. As of April 19, 2007, IRS processed about 3.7 million free file returns—less than 4 percent of eligible taxpayers and a decrease of 2.2 percent from the same period last year. IRS officials attributed this decline in part to companies offering free electronic on-line filing separate from the Free File program. While all 19 companies participating in the Free File program allow for TETR requests, only 3 of the 19 companies offer Form 1040 EZ-T requests. TETR and split refund volume has been less than IRS projected. Over 68 percent of individuals who filed returns through April 14 have requested the TETR, although all who paid the excise tax were eligible for the refund. IRS projected that 10 to 30 million individuals who did not have a tax filing obligation could claim TETR. As of April 13, approximately 578,000 of this group have asked for a refund (3.4 percent of the 17.1 million IRS expected by this time). As of April 21, just over 77,000 individual taxpayers chose to split their refunds into different accounts, which represent a small fraction of the 57.2 million taxpayers who had their refunds directly deposited and the 3.8 million split refunds IRS projected for the filing season. IRS delayed processing a small number of returns claiming tax extender provisions until February 3 to complete changes to its tax processing systems. IRS has anticipated some problems due to the late passage of extender provisions which prevented information about them included in printed tax publications. Finally, in order to minimize problems, IRS planned and prepared extensively for this year’s primary tax system changes: TETR, split refund, and tax law extenders. For example, IRS updated forms and created new ones, hired and trained additional staff to handle potential volume of TETR and split refund requests, and updated the Web site and tax systems. As reported in App. 1, of the tax systems changes, only TETR created new compliance concerns for IRS and IRS modified its plans to address those concerns during the filing season. The number of calls to IRS’s toll-free telephone lines has been less than last year and is significantly less for automated calls than in 2002 (see table 3). Similar to last year, IRS assistors answered over 40 percent of the total calls, while the rest of the calls were answered by an automated menu of recordings. By one measure of access, IRS’s performance is somewhat better and for another it is somewhat worse than this time last year. Taxpayers’ ability to access IRS’s toll-free telephone lines is somewhat better than last year, and IRS is meeting its annual goals. According to IRS officials, IRS does not try to match previous years’ performance, but sets and tries to achieve performance goals according to the budget received. As shown in table 4, the percentage of taxpayers who attempted to reach an assistor and actually got through and received services—referred to as the level of service—was one percentage point higher than the same time period last year and greater than IRS’s goal of 82 percent for both FYs 2006 and 2007. Average speed of answer, which is the length of time taxpayers wait to get their calls answered, is just under 4 minutes, almost 15 percent longer than last year, but better than IRS’s annual goal of 4.3 minutes. IRS estimates that the accuracy of telephone assistors’ responses to tax law and account questions to be comparable to the same time period last year by using a statistical sampling process. IRS officials noted that there was unprecedented hiring for FY 2007, and while every employee working tax law applications completes a requisite certification process, new employees will be less productive than experienced employees. IRS has implemented several initiatives, such as targeted monitoring and training, to assist the new hires. IRS officials reported that tax system changes have had minimal impact on telephone operations so far this filing season. TETR-related calls are a small fraction of the TETR calls that IRS projected and all calls that IRS received. Between January 1 and April 14, 2007, IRS expected 12.4 million TETR-related calls, but received about 540,000. IRS hired 650 FTEs in FY 2007, with the expectation that those hires would be used to cover anticipated attrition in 2008. Their first assignment was answering TETR telephone calls and they also were trained to handle other accounts calls allowing more experienced employees to address paper inventory. IRS anticipated little impact on telephone service from the split refund option and tax provision extenders. For split refunds, IRS anticipated it would receive about 70,000 calls to assistors compared to the 70 million total calls it receives each year. IRS did not have projections for tax provision extensions. Use of IRS’s Web site has increased so far this filing season compared to prior years except for downloads of forms and publications. From January 1 through March 31, IRS’s Web site was visited more often and the number of searches increased over the same time period as last year. However, the number of downloaded forms and publications has decreased 22 percent over the same period compared to last year. According to IRS officials, reasons for this decrease include the increase in taxpayers using e-file, tax preparation software, and paid preparers, negating the need for taxpayers to download and print forms and publications. In terms of new features, IRS added a state deduction calculator this filing season, which IRS wants to use as a new standard for developing other on-line calculators. Web site assistance is important because it is available to taxpayers 24-hours a day and it is less costly to provide than telephone and walk-in assistance. In addition to the Free File program, IRS’s Web site offers several important features, such as “Where’s My Refund”, which allows taxpayers to check on the status of their refunds. This year, the feature allows taxpayers to check on the status of split refunds, and tells the taxpayer if one or more of the deposits were returned from the bank because of an incorrect routing or account number. However, for certain requests, the feature is not useful. For example, IRS stopped some refunds related to TETR requests, but “Where’s My Refund” informed taxpayers that their refunds had been issued. Further, if taxpayers make a mistake calculating the amount of their refund the feature would indicate that IRS corrected the refund amount, but will not show the new amount. IRS is considering providing more information about taxpayer accounts on its Web site as part of its strategy to improve taxpayer services at reduce costs. There is further evidence that IRS’s Web site is performing well as these examples show. According to the American Customer Satisfaction Index, for January through March 2007, IRS’s Web site is scored above those of other government agencies, nonprofits, and private sector firms for customer satisfaction. For example, in March, IRS scored 74 versus 72 for all government agencies surveyed and 71 for all Web sites surveyed. An independent weekly study by Keynote, a company that evaluates Web sites, reported that, as of April 9, 2007, IRS’s Web site has repeatedly ranked in the top 6 out of 40 government agency Web sites evaluated in terms of average download time. Last year, IRS consistently ranked second for the same time period. Average download time remained about the same for IRS compared to last year, indicating that IRS is not performing worse, but that other government agencies are performing better. On the basis of our own searches, we found IRS’s Web site to be readily accessible, easy to navigate, and easy to search. As of April 14, approximately 2.9 million taxpayers used IRS’s 401 walk-in sites, which is comparable to the same period last year. Figure 5 shows the trend in walk-in site use for the filing season including slight projected declines in 2007 and 2008. At walk-in sites, staff provide taxpayers with information about their tax accounts, answer a limited scope of tax law questions about, for example, income and filing status, and provide limited tax return preparation assistance. As of April 14, over 10,700 taxpayers have requested TETR on Form 1040EZ-T at walk-in sites, which is 8.5 percent of the 126,000 individuals IRS expected. IRS officials attribute this year’s projected decline in walk-in use to taxpayers’ increased use of tax preparation software and IRS.gov. This decline has allowed IRS to devote 2.3 percent fewer FTEs compared to last year for walk-in assistance (down from 260 to 266 FTEs). Volunteer sites, often run by community-based organizations and staffed by volunteers who are trained and certified by IRS, do not offer the range of services provided at walk-in sites. Instead, volunteer sites focus on preparing tax returns primarily for low-income and elderly taxpayers and operate chiefly during the filing season. As of April 15, the number of taxpayers getting return preparation assistance at over 11,000 volunteer sites has increased to approximately 2.3 million, up 16 percent from last year and continuing a trend since 2001. Although no projections have been made for TETR claims, over 80,600 taxpayers have claimed this credit at these locations. We have reported that the shift of taxpayers from walk-in to volunteer sites is important because it has allowed IRS to transfer time- consuming services, such as return preparation, from IRS to other less costly alternatives that can be more convenient for taxpayers. While IRS is collecting better data on the quality of service at walk-in sites, concerns about quality of the data and service remain. According to IRS, it is measuring the accuracy of tax law and accounts assistance. IRS has reported a goal for tax law accuracy, and plans to use data collected for 2007 to set an annual goal for accounts accuracy. While IRS provided return assistance for almost 210,000 taxpayers, it lacks information on the accuracy of that assistance. For volunteer sites, as of April 12, for a small non-statistical sample, IRS reported a 64 percent accuracy rate for return preparation, compared to its goal of 55 percent. Independent from IRS, but using similar methods, TIGTA showed a 56 percent accuracy rate. IRS developed TAB to provide the agency with information on taxpayers’ needs and preferences to improve taxpayer service at lower cost as part of a 5-year plan, in response to a November 2005 law and a congressional directive. IRS notes that with TAB, it has more information than ever before about taxpayers, partners, employees, and the effect of service- related decisions on taxpayers to help the agency provide, evaluate, and improve services. IRS issued two reports under TAB: The Phase I report, released in April 2006, outlines the results of preliminary research on taxpayer expectations and establishes five strategic themes for improving taxpayer services. Phase II, released in April 2007, includes the results of additional research, numerous areas and initiatives both funded and unfunded for service improvement, and a set of recommended performance measures. IRS has identified 54 initiatives, some of which are underway, that include taxpayer service upgrades such as improvements to the Spanish version of “Where’s My Refund” and research studies. IRS identified 28 of the initiatives as unfunded and included several as part of its FY 2008 budget request as noted above. As part of its strategy, IRS developed estimates of the cost per service contact for providing different types of taxpayer services, although there were qualifications to those estimates. As table 6 indicates some assisted services, such as e-mail, are far more expensive than self-assisted services, such on IRS’s Web site. However, while there may be some overlap in services (e.g., taxpayers can receive similar return assistance at both walk- in sites and volunteer sites), they are likely to serve different taxpayers and may provide different levels of service (e.g., taxpayers can receive account assistance at walk-in sites, but not at volunteer sites). But, even between the two self-assisted options, there is a difference in unit costs, with automated phone calls estimated to be more than five times higher than Web contacts. Having reliable cost information, together with a better understanding of taxpayers’ preferences, needs, and expectations, could assist IRS in determining whether it could provide taxpayers with the same taxpayer service benefits at a lower cost through alternative methods. However, to further evaluate IRS’s strategy, additional information would be required, for example, on how savings estimates were developed. BSM is critical to supporting IRS’s taxpayer service and enforcement goals and reducing the tax gap. For example, BSM includes projects to allow taxpayers to file and retrieve information electronically and to provide technology solutions to help reduce the backlog of collections cases. Despite progress made in implementing BSM projects and improving modernization management controls and capabilities, significant challenges and serious risks remain, and further program improvements are needed, which IRS is working to address. Over the past year, IRS has made further progress in implementing BSM projects and in meeting cost and schedule commitments, but two key projects experienced significant cost overruns during 2006—CADE and Modernized e-File. During 2006 and the beginning of 2007, IRS deployed additional releases of the following modernized systems that have delivered benefits to taxpayers and the agency: CADE, Modernized e-File, and Filing and Payment Compliance (a tax collection case analysis support system). Each of the five associated project segments that were delivered during 2006 were completed on time or within the targeted 10 percent schedule variance threshold, and two of them were also completed within the targeted 10 percent variance threshold for cost. However, one segment of the Modernized e-File project as well as a segment of the CADE project experienced cost increases of 36 percent and 15 percent, respectively. According to IRS, the cost overrun for Modernized e-File was due in part to upgrading infrastructure to support the electronic filing mandate for large corporations and tax-exempt organizations, which was not in the original projections or scope. IRS has also made significant progress in implementing our prior recommendations and improving its modernization management controls and capabilities, including efforts to institutionalize configuration management procedures and develop an updated modernization vision and strategy and associated 5-year plan to guide information technology investment decisions during fiscal years 2007 through 2011. However, critical controls and capabilities related to requirements development and management and post-implementation reviews of deployed BSM projects have not yet been fully implemented. In addition, more work remains to be done by the agency to fully address our prior recommendation of developing a long-term vision and strategy for completing the BSM program, including establishing time frames for consolidating and retiring legacy systems. IRS recognizes this and intends to conduct further analyses and update its vision and strategy to address the full scope of tax administration functions and provide additional details and refinements on the agency’s plans for legacy system dispositions. Future BSM project releases continue to face significant risks and issues, which IRS is taking steps to address. IRS has reported that significant challenges and risks confront its future planned system deliveries. For example, delays in deploying the latest release of CADE to support the current filing season have resulted in continued contention for key resources and will likely impact the design and development of the next two important releases, which are planned to be deployed later this year. The potential for schedule delays, coupled with the reported resource constraints and the expanding complexity of the CADE project, increase the risk of scope problems and the deferral of planned functionality to later releases. Maintaining alignment between the planned releases of CADE and the new Accounts Management Services project is also a key area of concern because of the functional interdependencies. The agency recognizes the potential impact of these project risks and issues on its ability to deliver planned functionality within cost and schedule estimates and, to its credit, has developed mitigation strategies to address them. We will, however, continue to monitor the various risks IRS identifies and the agency’s strategies to address them and will report any concerns. IRS has also made further progress in addressing high-priority BSM program improvement initiatives during the past year, including efforts related to institutionalizing the Modernization Vision and Strategy approach and integrating it with IRS’s capital planning and investment control process, hiring and training 25 entry-level programmers to support development of CADE, developing an electronic filing strategy through 2010, establishing requirements development/management processes and guidance (in response to our prior recommendation), and defining governance structures and processes across all projects. IRS’s high- priority improvement initiatives continue to be an effective means of assessing, prioritizing, and incrementally addressing BSM issues and challenges. However, more work remains for the agency to fully address these issues and challenges. In addition, we recently reported that IRS could improve its reporting of progress in meeting BSM project scope (i.e., functionality) expectations by including a quantitative measure in future expenditure plans. This would help to provide Congress with more complete information on the agency’s performance in implementing BSM project releases. IRS recognizes the value of having such a measure and, in response to our recommendation, is in the process of developing it. IRS’s budget submission is important because it shows the resource tradeoffs IRS intends to make between enforcement and taxpayer service—both of which have potential to reduce the tax gap. One way that IRS reallocates resources is through new spending initiatives. However, in order for Congress and other external parties to assess the merits of new initiatives, basic information about the description of the initiatives and their costs and expected performance is necessary. Without such information, decisions makers do not have an informed basis on whether to approve and fund new initiatives. Of course, the costs of developing justifications must also be taken into account. More costly initiatives generally would be expected to have more detailed justifications. We recommend that the Commissioner of Internal Revenue have available basic descriptive, cost, and expected performance information on the spending initiatives proposed in the 2008 budget submission to the extent to such information has not been provided, and include in future budget submissions, basic descriptive, cost, and performance information on new spending initiatives, with supplementary documentation available if needed. In comments on a draft of this statement, IRS’s Chief Financial Officer agreed with the second recommendation, but not the first. She stated that the FY 2008 budget and justification did provide basic descriptive, cost, and expected performance information for each initiative. IRS agreed that the amount of performance data provided for each initiative varied, stating that some of the initiatives did not necessarily merit such performance indicators and, for those initiatives, IRS provided explanations of general benefits or reasons behind the request. While we agree that for every initiative IRS provided the total proposed spending, some initiatives lacked basic information on how the amount to be spent was determined and work to be done. For example, the initiative for improving compliance estimates provided no explanation of how the 258 FTEs were determined or basic information on the work such as the number of examinations to be conducted. Without such information, at the end of the fiscal year, Congress would be unable to tell whether IRS spent the money as intended. Mr. Chairman, this concludes my prepared statement.

TETR is the only one of the three tax changes that created new compliance concerns for IRS (filers could request greater TETR amounts than they are entitled to). The split refund option does not create compliance concerns for IRS since it relates to the accounts into which taxpayers want their refunds deposited rather than to complying with tax provisions. Since these provisions extending the tax laws already existed, IRS anticipates that any compliance concerns for 2006 returns will be the same as for previous years. IRS developed a plan before the filing season began to audit suspected TETR overclaims before issuing refunds. IRS’s plan for TETR was consistent with good management practices identified in previous GAO reports. IRS’s plan included appointing an executive, developing an implementation plan for TETR that included standard amounts that individuals could request, developing a compliance plan to select TETR requests for audit, and monitoring and evaluating compliance by using real-time data to adjust TETR compliance efforts. For example, each week, IRS reviews the requests for TETR, selects some for audit, and revises the criteria for audit selection as necessary. As of April 21, 2007, about 324,000 individuals had requested the actual amount of telephone excise tax paid for a total of $128 million. IRS selected about 3.4 percent of these requests for audit, involving about $33 million. IRS has closed 464 of the individual audits with the taxpayer agreeing to accept the standard amount; it has not completed the remaining individual audits. About 346,000 businesses had requested TETR for a total of about $161 million. IRS selected over 1,000 for audit, involving about $22 million. IRS has closed four business audits. IRS reassigned about 77 FTEs from discretionary audits and Earned Income Tax Credit audits to conduct TETR audits. Additionally, Criminal Investigation has spent 13 FTEs staff on TETR activities in 2007.

Summary: The Internal Revenue Service's (IRS) budget request shows how IRS intends to balance spending for enforcement and taxpayer service, including spending for new initiatives and the Business Systems Modernization (BSM) program. A combination of enforcement and taxpayer service promotes compliance with the tax laws. GAO was asked to (1) compare IRS's proposed FY 2008 budget to prior years' and assess how the new spending initiatives are justified, and (2) describe IRS's enforcement, filing season, and BSM performance. GAO analyses are based on IRS's 2008 budget submission, supplementary IRS data, interviews with IRS officials, and prior GAO reports. Some of GAO's analyses have been reported earlier this year and updated here. IRS's budget proposes to increase spending by almost 5 percent to $11.6 billion. The budget proposes shifting a greater proportion of spending to enforcement, continuing a trend since 2004. IRS projects that revenue from the new initiatives will have a relatively small impact on the tax gap--less than one percent of the gap last estimated at $290 billion in 2001. The tax gap is the difference between what taxpayers owe and voluntarily pay. Justifications for the new initiatives varied with some lacking descriptive, cost, and expected performance information. For example, an initiative for improving compliance estimates provided no information on how the budget and staff needed or work to be done were determined. Without such information, decision makers do not have an informed basis for approving and funding the new initiatives. IRS has made noticeable progress in its enforcement efforts including increasing the amount of enforcement revenue collected and enforcement staffing. For example, between FY 2004 and 2006 enforcement revenue increased 13 percent to $48.7 billion. Nevertheless, enforcement remains on GAO's high-risk list. The tax gap has been a persistent problem in spite of efforts to reduce it, as the rate of taxpayers' voluntarily compliance with the tax laws has changed little over the past three decades. To better target enforcement resources, IRS has requested funding to do additional compliance research which GAO has long supported. Finally, GAO has reported on IRS's lack of a data-based plan to improve compliance. Filing season performance in 2007 improved in some areas compared to prior years', but there have been challenges. As of April 20, IRS processed about 104.6 million individual income tax returns and issued 88.2 million refunds. Electronic filing grew, telephone access is somewhat better, and Web site use continues to grow. However, fewer than 4 percent of eligible taxpayers used the Free File program. The latest release of Customer Account Data Engine (CADE), the new tax processing system, was delayed. As a result, millions of taxpayers did not benefit from CADE's faster processing of refunds. IRS recently issued its plan, the Taxpayer Assistance Blueprint, to improve taxpayer service. Despite progress in implementing BSM projects including for CADE and improving management controls and capabilities, significant challenges and serious risks remain. Delays in the latest release of CADE resulted in continued contention for key resources and will likely impact future releases. IRS has more to do to address GAO's prior recommendations such as developing a long-term strategy that would include time frames for retiring legacy computer systems.
