Tax Administration: IRS Improved Performance in the 2004 Filing
Season, But Better Data on the Quality of Some Services Is Needed
(15-NOV-04, GAO-05-67).

Most taxpayers have their only contact with IRS during the filing
season, with tens of millions filing their returns, getting
refunds, and seeking assistance by calling or visiting IRS's
offices or Web site. GAO was asked to assess IRS's performance in
2004 relative to goals and prior years' performance as well as
initiatives or other factors that significantly affected
performance for the following areas: (1) the processing of paper
and electronic returns, (2) telephone service, (3) walk-in
service, and (4) Web site service.

IRS Improved Performance in the 2004 Filing Season, But Better Data on the
Quality of Some Services Are Needed

What GAO Found

During the 2004 filing season, IRS met many of its performance goals and
continued a trend of improvement in recent years. However, IRS did not
improve in all dimensions of its filing season services and lacks
sufficient data to evaluate quality in others.

IRS processed returns and issued refunds smoothly. The proportion of
returns filed electronically is up to 47 percent. Despite this achievement
and numerous initiatives to increase electronic filing, IRS does not
expect to reach its long-term goal of having 80 percent of all individual
tax returns filed electronically by 2007. A higher percentage of taxpayers
was able to reach IRS assistors by telephone than last year and the
accuracy rate for providing taxpayers with information about their
accounts remained stable. However, the accuracy rate for answering tax law
questions declined to 2001 levels. Consistent with IRS's strategy, the
number of taxpayers visiting IRS walk-in sites declined, while the number
having tax returns prepared at volunteer sites increased. Finally,
although IRS continued to expand its Web site services, the site's feature
for answering tax law questions raises some concerns.

Despite the 2004 improvements, IRS has opportunities for further service
improvements. For example, IRS has limited data with which to assess the
quality of key services at its walk-in sites and sites staffed by
volunteers. Although IRS has initiatives under way to measure quality at
both types of sites, the initiatives have been delayed and important
details have not yet been determined, which may undermine IRS's efforts to
improve services in this area. In the meantime, some of IRS's quality data
is likely to be biased. Until IRS fully implements its initiatives and
gathers data on quality, it will have difficulty monitoring and improving
performance at its walk-in sites and volunteer sites.

The Honorable Amo Houghton
Chairman, Subcommittee on Oversight
Committee on Ways and Means
House of Representatives

Dear Mr. Chairman:

Most taxpayers have their only contact with the IRS during the tax filing
season1 making the agency's performance during this period a key indicator
of how well IRS is serving the public and helping them fulfill their tax
obligations. IRS's filing season is an enormous undertaking, requiring
thousands of IRS staff years to process well over 100 million individual
income tax returns, issue refunds, and respond to telephone calls and other
requests for assistance. To the extent that IRS can improve filing season
operations and provide services more efficiently, it could shift resources to
other areas such as enforcement.

Because of the importance of IRS's filing season activities to taxpayers and
the Congress, you asked us to assess the 2004 tax filing season. Our
objectives were to assess IRS's filing season performance, relative to this
year's goals and prior years' performance, and any initiatives or factors that
significantly affected performance. We did this for (1) the processing of
individual tax returns filed on paper or electronically, (2) tollfree
telephone service, (3) walkin and volunteer site service, and (4) IRS's
Internet Web site. We testified on IRS's interim performance in a hearing
held by your Subcommittee on Oversight, Committee on Ways and Means
on March 30, 2004.2

Our assessment is based on reported results and analyses of key IRS
performance measures and data, observations of IRS's operations,
interviews of IRS officials, information from representatives of the tax
practitioner community, and analyses by the Treasury Inspector General
for Tax Administration (TIGTA). For the purpose of this report, we found

1 Most taxpayers file their tax returns between January 1 and April 15, which is the deadline for filing individual income tax returns. However, millions of taxpayers receive extensions from IRS, which allows them to delay filing until as late as October 15.

Request and 2004 Filing Season Performance,
GAO04560T (Washington, D.C.: Mar. 30, 2004).

IRS's data to be sufficiently reliable for assessing IRS's 2004 filing season performance and for comparison to prior filing seasons. Further details on our scope and methodology are provided later in this report. We performed our work from January through September 2004 in accordance with generally accepted government auditing standards.

Results in Brief
During the 2004 filing season, IRS met many of its performance goals and continued a trend of improvement in recent years. However, IRS did not improve in all dimensions of its filing season services and lacks sufficient data to evaluate quality in others.

Processing: IRS nearly met or exceeded most of its 2004 goals for processing tax returns and issuing refunds. Performance has generally improved since 2001. Over 61 million returns or 47 percent of all individual income tax returns were electronically filed in 2004. Despite this achievement and numerous initiatives to increase electronic filing, IRS does not expect to meet its longterm goal of having 80 percent of all individual tax returns filed electronically by 2007.

Telephone Service:
Access to IRS assistors increased and the accuracy of IRS's response to account questions has remained stable since last year. However, the accuracy rate for responding to tax law questions declined for the second consecutive year and is at the same level as 2001.

Walk-in
Assistance: The number of taxpayers visiting IRS walkin sites continued to decline in the 2004 filing season, while the number receiving return preparation assistance at nonIRS sites staffed by volunteers increased, consistent with IRS's strategy to shift return preparation to those sites. Available, but limited, data raise questions about the quality of key services provided at both types of sites. In addition, some of the quality data IRS expects to have available in 2005 is likely to be biased. Initiatives under way to improve quality measurement have experienced delays, and important details have not yet been determined.

Internet Web Site: IRS's Web site is generally easy to access and use. However, we still have some concerns about IRS's performance answering tax law questions submitted via the site.

We are making recommendations to the Commissioner of Internal Revenue that IRS recognize and disclose the limitations of the performance data that will be collected at walkin sites in the 2005 filing season; take steps to

ensure that its initiatives to improve data on the quality of services at walkin and volunteer sites are implemented in a timely manner; and recognize that decisions about the prominence and staffing to give its Web site feature for answering tax law questions are related. In commenting on a draft of this report (see app. III), IRS agreed with the recommendations about walkin and volunteer site initiatives. Additionally, IRS agreed with the intent of the other two recommendations, but disagreed with our assessment of the extent of the problems. However, without stronger evidence, such as statistically valid data, our concerns remain.

Scope and Methodology

Our assessment of IRS's 2004 filing season performance was based on analyses of IRS data and information obtained from sources outside IRS, interviews with IRS officials and private sector tax practitioners, observations of IRS operations, and, for the comparison to previous years, on our past filing season reports.

More specifically, we

o
reviewed and analyzed IRS reports, testimonies, budget submissions, other documents and data, including workload data and data from IRS's current suite of balanced performance measures, which we used to assess performance this year;

o
interviewed IRS officials about current operations, performance relative to 2004 goals and prior filing seasons, and significant factors and initiatives that affected performance;

o
interviewed representatives of large private and nonprofit organizations that prepare tax returns and trade organizations that represent both individual practitioners and tax preparation companies;

o reviewed related TIGTA reports and interviewed TIGTA officials;

o
followed up on GAO recommendations made in prior filing season and related reports;

o
tested for statistical differences between yearly changes for various IRS performance measures;

o
analyzed information posted to IRS's Internet Web site based on GAO's knowledge of the type of information taxpayers look for, and assessed

the ease of finding information, as well as the accuracy and currency of data on the site;

o
reviewed information from companies that evaluated Internet performance and assessed various aspects of IRS's Web site; and

o
reviewed staffing data for paper and electronic processing, telephone assistance, and walkin assistance.

This report discusses filing season performance measures and data covering the quality, accessibility, and timeliness of IRS's services. We have previously reported that some of the performance measures IRS uses to assess aspects of its filing season performance had attributes of successful measures, including objectivity and reliability, although in some cases, the measures could be further refined.3 Since that report, IRS has made refinements in some measures. We also reviewed IRS documentation, interviewed IRS officials about computer systems and data limitations, and compared those results to GAO standards of data reliability.4 As a result, we determined that the IRS data we are reporting are sufficiently reliable for assessing IRS's filing season performance. Data limitations are discussed where appropriate.

We conducted our work at IRS headquarters in Washington, D.C.; the Small Business/SelfEmployed Division headquarters in New Carrollton, Maryland; the Wage and Investment Division headquarters, the Joint Operations Center (which manages telephone service), and a telephone call site in Atlanta, Georgia; and walkin and volunteer locations in Georgia, Maryland, and Virginia. We selected these offices for a variety of reasons, including the location of key IRS managers, such as those responsible for telephone and walkin and volunteer services. We performed our work from January through October 2004 in accordance with generally accepted government auditing standards.

Season Performance Measures, GAO03143 (Washington, D.C.: Nov. 22, 2002).

Data, GAO0215G (Washington, D.C.: Sept. 1, 2002).

Background
IRS's filing season is an enormous and critical undertaking that includes two key activities-returns processing and taxpayer assistance-and which consumes thousands of staff years annually. Processing of paper returns is labor intensive and errorprone. IRS employees manually transcribe paper tax return information into IRS's computer systems, which can introduce errors. Electronic filing allows taxpayers to receive refunds faster, and processing is less laborintensive and error prone than for paper returns. IRS does not have to transcribe electronic tax return information and builtin checks eliminate many errors that IRS has to deal with when processing paper tax returns, such as computational mistakes and incorrect social security numbers. The rate for this type of error on electronic tax returns was almost 4 percent compared to almost 25 percent on paper tax returns, as of July 9, 2004.

To help taxpayers comply with their tax obligations, IRS provides various services at its call sites, walkin sites, and on its Web site. Figure 1 shows how tollfree telephone calls from taxpayers typically are routed through IRS's telephone system and answered by customer service representatives (CSRs) or by automated services.

Figure 1: How IRS Typically Routes Taxpayers' Calls to Toll-Free Numbers

Source: GAO analysis of IRS data and Art Explosion.

At IRS's approximately 400 walkin sites taxpayers ask tax law questions, get account information, receive assistance with their accounts, and have returns prepared (if annual gross income is $35,000 or less). In addition, lowincome and elderly taxpayers get tax returns prepared at over 13,500 volunteer sites5 run by communitybased coalitions that partner with IRS. IRS awards grants, trains and certifies volunteers, and provides reference materials, computer software and, in some cases, computers to these volunteer organizations.

IRS's Web site is important because it allows taxpayers to instantly download hundreds of tax forms and publications, access current information on tax issues and electronic filing, and ask IRS tax law and procedural questions.

5 Most volunteer sites have limited days and hours of operation and are open primarily between January and April 15.

Since passage of the IRS Restructuring and Reform Act of 19986 (RRA 98), IRS has been focused on improving filing season services. In 2001, IRS established a suite of balanced performance measures.7 The system emphasizes accountability for achieving specific results and reflects IRS's priorities, including providing quality service to each taxpayer in every interaction. As part of its strategic planning and budgetary processes, IRS establishes performance goals each fiscal year8 and uses them to hold managers and frontline staff more accountable for improving filing season performance.

IRS Has Generally Improved Its Performance Processing Tax Returns but Does Not Expect to Meet Its LongTerm Electronic Filing Goal

IRS processed individual income tax returns and issued refunds smoothly in 2004. IRS nearly met or exceeded many of its 2004 performance goals, with performance generally improving since 2001. However, despite continued growth this year and despite various initiatives to encourage electronic filing, IRS is not on track to achieve its longterm goal of having 80 percent of all individual tax returns filed electronically by 2007.

As of September 17, 2004, IRS had processed about 128 million individual tax returns, including for 67 million returns filed on paper, with no significant disruptions and issued nearly 100 million refunds within specified tolerances.9 According to IRS data, IRS nearly met or exceeded seven out of its eight processing performance goals in 2004. Similarly, 2004 performance nearly met or exceeded 2003 performance for six of the seven comparable measures.10 Appendix 1 provides details. Furthermore, as Appendix 1 and the following examples show, IRS has generally improved its processing operations over a longer period.

6 P.L. 105206, July 22, 1998.

7 IRS's balanced measures system is consistent with the Government Performance and Results Act of 1993 (P.L. 10362), which was enacted to hold federal agencies accountable for achieving program results (See GAO03143).

8 Although IRS establishes goals for its balanced measures on a fiscal year basis, our assessment of these measures was based on different times during the filing season, depending on the filing season activity being assessed.

9 Time periods covered for paper returns and refunds were January 1 through September 17, 2004.

10 IRS's measure for deposit timeliness for 2004 was not comparable to previous years because IRS changed the formula to not include weekends in calculating timeliness.

o
The percent of notices with errors has declined since 2002 (for notices sent to taxpayers about possible simple mistakes on their returns). In 2002, 18.7 percent of the notices were issued with errors compared to 9.4 percent as of July 31, 2004 (the most current data available).

o
The refund error rate, the percentage of refunds with IRScaused errors (e.g., incorrect name or Social Security number), has decreased from 9.8 percent in 2001 to 5.3 percent in 2003, to 4.9 percent as of July 31, 2004 (the most current data available).

Tax practitioners, who last year prepared approximately 62 percent of all individual income tax returns, agreed that the processing of returns in the 2004 filing season has gone smoothly. Representatives from the National Association of Enrolled Agents, American Institute of Certified Public Accountants, and other tax related organizations had positive comments on IRS's 2004 filing season and processing. Similarly, TIGTA officials told us that IRS generally processed returns smoothly in 2004.

IRS officials attributed this year's performance in part to their planning for tax law changes, such as the advance child tax credit and the increase in electronic filing.

Electronic Filing Grew but Is Not on Track to Achieve LongTerm Goal

The number of individual income tax returns that IRS received electronically continued to grow, and IRS exceeded its 2004 goals for the number and percentage of tax returns to be filed electronically. From January 16 through September 17, 2004, it had received an estimated 61.1 million individual tax returns electronically or 47 percent of all returns filed to date. Also, the growth rate of 15.8 percent is greater than IRS's projected growth rate of 13 percent for this year. Figure 2 shows that growth since 1996.

Figure 2: Percent of Tax Returns Filed Electronically 1996-2004

0 1996 1997 1998 1999 2000 2001 2002 2003 2004

Source: GAO analysis of IRS data.

According to IRS officials, the primary reason for the greater than expected growth rate is that five states mandated electronic filing of state tax returns prepared by qualified tax practitioners for 2004. According to these same officials, these mandates led to significantly more electronic filing of federal tax returns in these states because tax practitioners converted their entire practices to electronic filing. For example, for California and Michigan, the largest of the five states, the number of tax returns filed electronically increased from 4.7 million and 1.9 million in 2003 to 7.1 million and 2.6 million respectively as of May 2004.

The current rate of growth of electronic filing, however, will not allow IRS to achieve its longterm electronic filing goal of 80 percent of all returns by 2007, provided by RRA 98. Assuming a continuation of the current growth rates of 15.8 percent for individual returns filed electronically and .23 percent for the total number of individual tax returns filed, IRS would receive 73 percent of individual tax returns electronically by 2007.

However, neither IRS nor the Electronic Tax Administration Advisory Committee (ETAAC)11 expects IRS to maintain this year's growth rate. In fact, IRS is predicting declining growth rates of about 11.5 percent, 9.9 percent, and 8.1 percent in 2005, 2006 and 2007, respectively. In its June 30, 2003, report to Congress, ETAAC concurred with IRS's prediction of lower annual growth rates.

IRS officials stated that achieving the 80 percent goal would require taxpayers and tax practitioners who prepared 39 million individual income tax returns12 on a computer but filed them on paper would instead have to file them electronically, or legislation would have to be proposed and passed that mandates electronic filing by tax practitioners.

Electronic filing is important because, according to IRS, it costs less to process electronic tax returns than paper tax returns. IRS estimates it saves $2.15 on every individual tax return that is processed electronically. However, we cannot independently verify this estimate and its basis is unclear, because as we have reported, IRS does not have a cost accounting system to support preparation of such cost estimates.13 Electronic filing has allowed IRS to close paper processing centers, devote less staff to the processing of tax returns, and control processing costs by shifting resources from laborintensive paper return processing to other areas, such as compliance. For example, with the elimination of paper tax return processing at the Brookhaven Submission Processing Center, IRS used about 1,000 fewer staff years to process paper returns in 2003 than in 2002, and plans additional staffyear savings when paper tax returns processing at the Memphis Submission Processing Center is eliminated in 2005. (See app. 2 for more information on staff years).

Because increasing electronic filing is so important, IRS officials do not want to reduce the 2007 goal, even though IRS projects that it is not

(Washington, D.C., June 2003). RRA 98 mandated that the Secretary of the Treasury convene an electronic commerce advisory group to ensure that the Secretary receives input from the private sector on IRS's plan to increase electronic filing.

achievable. Retaining this goal serves as a symbol of their determination to take actions to convert taxpayers to file electronically.

IRS Has Taken Numerous Actions to Encourage More Electronic Filing

Over the years, IRS has taken numerous actions to encourage electronic filing, including

o
making electronic filing free to most taxpayers via the Free File Alliance Program,14 a program that began last year;

o
surveying taxpayers and tax practitioners in response to a recommendation in our 2001 filing season report 15 to determine why 40 million tax returns were prepared on a computer but filed on paper;

o
making over 99 percent of all individual tax forms suitable for electronic filing; and

o
making the process totally paperless if a person uses a personal identification number to sign the tax return.

For the 2004 filing season, IRS took the following actions to encourage taxpayers and practitioners-primarily those who prepared returns on a computer, but filed them on paper-to file electronically IRS. IRS

o
improved the Free File Alliance Program (as of September 17, 2004, about 3.5 million individual tax returns have been filed electronically via the Free File Alliance, compared to 2.8 million for all of last year, a 26 percent increase);

o
contacted about 12,200 tax practitioners who prepared business returns on computers, but filed electronically to advise them about the benefits of electronic filing;

14 In 2003, IRS entered into a 3year agreement with the Free File Alliance, a consortium of tax preparation companies that provides free electronic filing to taxpayers who access any of the companies via a link on IRS's Web site. IRS is currently in the second year of the initiative, and 17 companies offered free filing via IRS's Web site.

15 GAO, Tax Administration: Assessment of IRS' 2001 Tax Filing Season,
GAO02144, (Washington, D.C.: Dec. 21, 2001).

o
targeted the approximately 8 million individual taxpayers who filed their own paper returns prepared on a computer by mailing them a modified version of Publication 8160E that cites the advantages of electronic filing;

o spent $11.2 million marketing electronic filing; and

o made six more forms available for electronic filing.

Other major electronic filing initiatives could lead to more individual electronically filed tax returns starting in 2005. However, IRS did not expect the following initiatives to dramatically increase electronic filing in 2004 because taxpayers and practitioners will need time to adjust their behavior.

o
The modernized Efile program, which for the first time, allows electronic filing of corporate tax returns, could lead to more individual tax returns being filed electronically. According to IRS officials, some tax practitioners reported they would not file electronically until they could do so for both individual and corporate tax returns, saying it did not make business sense to file tax returns two different ways.

o
The Eservices program, offered to tax practitioners who have filed at least 100 electronic tax returns, gives them the ability to conduct business, such as electronic account resolution and transcript delivery with IRS electronically 24 hours a day 7 days a week for services.

Despite these initiatives, IRS does not expect to reach its 2007 goals for electronic filing. However, because of the potential for cost savings, we continue to see value in such initiatives.

Access to IRS's IRS exceeded its 2004 telephone service goal for access to customer

service representatives (CSRs) and has improved in this area since 2001.Telephone Assistors However, the accuracy of CSR answers to tax law questions declined. IRS Improved but Tax Law initiated two pilots in 2004 to help assess options for improving its Accuracy Declined telephone service.

Access to Customer Service Representatives Continued to Improve; the Accuracy of Account Inquiries Was Stable; but the Accuracy of Tax Law Questions Declined

IRS received 84 million calls on
its tollfree telephone lines in 2004 through midJuly. Figure 3 shows that almost half
of those calls were from callers trying to obtain information on
the status of
their tax refunds; the rest were primarily account or tax law questions.

Figure 3: Reasons Taxpayers Called for Telephone Assistance During the

Note: The "other" category includes, for example, special telephone
numbers not available to the public, such as those for disaster relief,
tax practitioners, and calls that were received on the automated services
line that were abandoned. Data cover the period January 1, 2004 through

As table 1 shows, compared to last year, access to CSRs continued to
improve, the average time taxpayers waited for CSRs remained stable, and
the accuracy of CSR responses to account questions remained stable, while
the accuracy of CSR responses to tax law questions declined.

recommended that IRS develop a customer satisfaction survey to measure approval of the automated service. At the time, the IRS Commissioner responded that he agreed that measuring customer satisfaction for
automated service was important. According to IRS officials, the needed computer programming changes were not done for the 2004 filing season, but are in the queue to be done when programming resources permit.

IRS officials continue to attribute the decline in tax law accuracy rate

questions. Last year, we reported18 that IRS attributed
the decline in the tax
law accuracy rate on a new format for the P&R guide, among other factors.
At that time, an IRS official believed that after CSRs became familiar with the guide, the problem would be resolved and IRS continued using the new format. IRS began to address the problems with the P&R
guide during the 2004 filing season. For example, CSRs told us that they attended a meeting of managers and CSRs in March 2004 to identify the problems with the guide and develop an action plan to correct the problems.
According to IRS officials, IRS tested changes to the guide at the St. Louis, Missouri and Cleveland, Ohio call sites in June 2004. In addition, IRS has a written plan
with deadlines for testing the guide for the 2005 tax filing season. The new
guide was to be made available in hardcopy
by October 1, 2004 and was to be used for purposes of training employees before the start of the 2005 filing season.

IRS Initiated Two Pilot Programs For Telephone Service

IRS initiated two pilot programs in 2004 to assess options for
improvements on its tollfree telephone services. IRS piloted having a
contractor answer tax law questions instead of IRS employees to determine (1) if a contractor could deliver an equal or superior level of service and (2) the public's
perception regarding being assisted by someone other than
IRS employees. IRS routed 10 percent of the tax law
calls19 received on its
tollfree lines to a contractor for 60 days (February through April 2004). With respect to the accuracy of tax law responses provided to taxpayers, the contractor's performance was about half that of IRS's-44.6 versus 82.46 percent, respectively. IRS attributed the contractor's performance to
a longerthanexpected learning curve. Also, taxpayers' raised concerns
regarding privacy, although no confidential information is shared in
answering tax law questions. In September 2004, IRS officials decided not
to go forward with further testing.

The second pilot was for contact recording, which involves recording all
telephone contacts between taxpayers and CSRs and, for 10 percent of the calls, also capturing computer screen displays accessed by the CSR. It is
intended to enable supervisors to provide CSRs with more complete

feedback on their performance. Figure 5 illustrates the process for contact
recording.

IRS conducted the contact recording pilot
from January through April 2004 at three call
sites. According to IRS officials and our interviews with
CSRs, CSRs liked being able
to hear and see how they handled calls. In September
2004, IRS officials told us that they had decided to implement contact
recording at all call sites by the end of the 2005 filing season.

Taxpayer Use of IRS Walkin Sites Continued to Decrease While Use of Volunteer Sites Increased; Quality Data Are Limited

The total number of taxpayers visiting IRS walkin sites continued to
decrease while those having their returns prepared at volunteer sites
increased. Available data raise questions, however, about the quality of
services provided at both walkin and volunteer sites. IRS has initiatives under way intended to improve the quality of data, though implementation may not be ready for the 2005 filing season.

Number of Taxpayers Based on the data obtained from IRS and shown in figure 6, the total Visiting IRS
Walkin Sites number
of taxpayers seeking assistance at IRS sites declined an average of Decreased While Number At
over 8 percent per year between 2001 and 2004. IRS officials attributed the

overall decrease to taxpayers' use of more convenient means to obtainVolunteer Sites Increased
services, such as IRS's tollfree telephone lines and Web site. Taxpayers

seeking return preparation assistance at walkin sites decreased an average
of 26 percent per year between 2001 and 2004.

In contrast, since 2001, the number of taxpayers seeking return preparation assistance at volunteer sites increased an average of 19 percent per year. During the 2004 filing season, taxpayers had over five times more returns prepared at volunteer
sites than at IRS walkin sites.
These divergent trends reflect IRS's strategy to shift return preparation to sites staffed by volunteer and communitybased coalitions that are overseen by IRS. IRS has
encouraged the shift by advertising the locations of these sites.

Note: "Other walk-in contacts" includes assistance for account notices,
tax law inquiries, forms, and
compliance work, but not return preparation. For the walk-in sites, the
time periods covered are
December 31, 2000 through April 28, 2001; December 30, 2001 through April
27, 2002;
December 29, 2002 through April 26, 2003; and December 28, 2003 through
April 24, 2004. For
volunteer sites, the time period covered for 2001 is January 1, 2001
through April 21, 2001; all other
periods are the same as those for IRS walk-in sites.

The shift of taxpayers from walkin to volunteer sites is important because
it has transferred some timeconsuming services, such as return
preparation, from IRS to volunteer sites. It also enabled IRS to
shift more

taxpayers to its telephone and Web site services, allowing it to
concentrate on services at walkin sites that only IRS can provide, such as account
assistance or compliance work (see app. 2).

Limited Data Raise Questions About the Quality of Services
at Walkin and Volunteer Sites

While shifting taxpayers from
IRS walkin sites to volunteer sites has the advantage of freeing up some IRS resources, IRS has limited performance measures and data
on the quality of tax law assistance, account assistance,
timeliness, and return preparation provided at either type of site. We have noted in prior filing season reports that this raises concerns about quality and oversight.20

o Tax Law Assistance: Both TIGTA and IRS reported that IRS had not
reached its goal of 80 percent accuracy at the walkin sites they visited.21
Since the sites were selected judgmentally, the results cannot be projected to all sites.

o Account Assistance: During the 2004 filing season, IRS did not measure
account assistance accuracy at its walkin sites. According to IRS
officials, the focus on tax law accuracy diverted staffing resources from gathering data on account assistance accuracy.

o
Timeliness: IRS also did not measure timeliness, although GAO has recommended22 that IRS readopt a timeliness measure for its walkin sites, stating that the presence of a quality measure should provide balance and a disincentive for employees to ignore quality in favor of timeliness.

Season, GAO01158 (Washington, D.C.: Dec. 22, 2000). Also, see GAO03143 for
further discussion of data and measures for IRS walkin sites.

at the Taxpayer Assistance Centers Could be
Improved, Reference No. 200440152 (Washington, D.C.: 2004).

22 GAO03143.

o Return Preparation: The utility of the current measure for accuracy of
return preparation assistance provided at walkin and volunteer sites is
limited, because it narrowly defines accuracy. It counts a return as accurate only if no calculation errors or other obvious factual errors, such as omitted or inconsistent data, are identified on the return. In addition, the results of recent TIGTA audits raise questions about the
accuracy of return preparation assistance at both walkin and
volunteer sites.23

IRS Has Initiatives Under Way Intended
to Better Measure Quality at Walkin and Volunteer
Sites Though Implementation May Not be Timely

IRS has initiatives under way intended to better measure the quality of key services at walkin and volunteer sites. Key parts of both the walkin and volunteer site initiatives that were scheduled for implementation in 2005, have experienced delays, have important details to be determined, and may not be implemented on schedule. The initiative for walkin sites has the following four components.

o Embedded Quality provides a standardized checklist for managers to
measure the accuracy, professionalism, and timeliness of employee responses to taxpayers. Initially under Embedded Quality, a manager
will directly observe the employee/taxpayer interaction. However, this could yield biased data, because employees will know they are being observed, which could influence their behavior. Consequently, Embedded Quality data gathered by direct observation may not be representative of true performance.

o Contact Recording24
will replace direct observation as the method for gathering data on Embedded Quality. Under contact recording, the
IRS employee/taxpayer interactions will be recorded and a random sample
assessed using the Embedded Quality checklist. A pilot was scheduled to begin in August 2004. According to IRS, as of September, the Department of Treasury
has not yet approved the pilot. It is unlikely the pilot will
begin until January 2005. Since the pilot and evaluation are

for IRS's telephone system.

planned to take 3 months, it is also unlikely that contact recording will
be fully implemented until well into the 2005 filing season.

o Q-Matic
is an automated system that keeps track of such things as customer waittime, assistance provided, and staff time used. As of
September 2004, QMatic implementation is proceeding on schedule.

o Performance-based individual
learning (ELearning) is a training component that will be used to identify and address deficiencies.

Until contact recording replaces direct manager observation as a means of gathering data, IRS may have biased data on the quality of its walkin services. Such biased data has significant limitations for drawing conclusions regarding performance and for making comparisons to other
years. This in turn creates difficulties for managers trying to identify
problems and make improvements to service. Furthermore, until
Embedded Quality and contact recording are implemented together for a
full filing season, assessing quality at walkin sites will be based on two different data collection methods, thus limiting comparisons.

At volunteer sites, IRS plans to implement the following;

o Quality Assurance is an initiative where IRS, working with volunteer
and communitybased coalitions, is developing quality standards and a means of monitoring the quality of return preparation services.25 This is
consistent with an earlier recommendation we made for IRS to develop performance measures for volunteer sites to help ensure that taxpayers were receiving an adequate level of service.26 IRS planned to implement
the initiative for the 2005 filing season. However, as of September 2004,
IRS had missed its milestones for developing guidelines for monitoring volunteer
sites, and was still developing and revising its implementation plans, revising its schedule, and determining important details, such as
how and when volunteer sites will be monitored and how quality will be
measured.

25
According to IRS officials, IRS and members of communitybased coalitions will likely
share responsibility for monitoring volunteer sites. IRS officials will conduct various types
of visits to volunteer sites. With some visits, IRS
officials will visit a statistically valid
sample to observe volunteers and operational procedures. With others, they
will have returns prepared by volunteers, similar to TIGTA's audit
in the 2004 filing season.

26 GAO01158.

We are concerned that the Quality Assurance initiative may not be implemented in
time to measure performance for the
2005 filing season. As with IRS's initiative for its walkin
sites, until Quality Assurance is fully implemented, IRS will
continue to have limited and potentially unreliable
information on the quality of return preparation at volunteer sites for the
2005 filing season. As a result, IRS officials have less information available when making decisions about the role of volunteer sites and how IRS should support them.

Use of IRS's Web Site Increased, But Concerns Exist About a Feature for
Answering Tax Law Questions

IRS's Web site is important because it provides taxpayers and tax practitioners with customer service without having to directly contact IRS employees. Although overall Web site usage increased over last year, we have some concerns about IRS's performance answering tax law questions.

Web Site Use Increased and the Site Was User Friendly and Highly Rated

IRS's Web site usage increased in 2004, continuing a trend as shown in table
2.27 Further, there was extensive use of the "Remember Your
Advanced Child Tax Credit" feature that was new in 2004.

27 IRS officials believe that the 2004 Forms, publications and other
documents download figure reported in table 2 is understated when compared
to last year for two
reasons. First, a major Form 1040 file was not formatted the same as last
year by error, resulting in significantly
fewer downloads being reported. Second, taxpayers can now view publications
and instructions directly via the Web site's normal search function and these views
do not count as
the form being downloaded. Evidence exists to support IRS's contention that
downloads would have been higher.

Source: GAO analysis of IRS data.

Note: All figures rounded to closest million, as of August 31, 2004.

Overall we found that
IRS's Web site was userfriendly and generally easy to
access and use. For example, based on our knowledge of the type of information taxpayers look for, we found (1) no broken links or outdated
or inconsistent data; (2) facts and information were logically arranged and easy to obtain; (3) with few
exceptions, search functions guided us to
appropriate forms, publications and information; and (4) response time was quick. However, we still have concerns about the feature answering tax law questions.

Two independent assessments done by Keynote and Brown University's
Center for Public Policy confirmed our observations on IRS's Web site.

o
Keynote, an independent Web site rater of Internet performance, reported that IRS's site performed very well. Keynote reported that, for
the average delivery time to download to IRS's Web site homepage, IRS was in the top 10 out of 40 government agencies measured for 12 of 15 weeks during the filing season. It also reported that, during the filing
season, IRS's response time was consistent with other organizations being measured. Finally, Keynote reported that, when it comes to success rate (being able to access a desired location on the Web site) IRS was always at 99 or 100 percent for the filing season.

o Brown
University's Center for Public Policy rated IRS's Web Site 5th out
of 60 federal government Web sites in providing service to citizens.

Performance and Use of Tax Law Assistance Feature Declined

The quality of IRS's Electronic Tax Law Assistance (ETLA) feature, which enables taxpayers and practitioners to ask tax law questions via the Internet and receive an email response from IRS, has declined. Usage has also declined, apparently by design.

IRS did not meet its 2004 goal to respond to email questions within 2
business days. On average, IRS responded to email questions in over 3
business days and only reached the 2 business day goal in 6 of the 27
tax law categories. Neither did IRS meet its accuracy goal. IRS's performance data showed that IRS answered about 64 percent of the email
questions accurately, compared to its goal of 78 percent.

IRS did not meet its goals because of a mismatch between the number of
questions from taxpayers and staff available to respond to the questions. At the beginning of the 2004 filing season, IRS increased the prominence of
the ETLA feature. However, an IRS official told us that this resulted in the site receiving more questions than staff could handle. The official said that
in response IRS moved the ETLA feature to a less prominent position on the Web site. In fact, in its current location, IRS does not expect taxpayers to be aware of the ETLA feature unless they stumble upon it
accidentally while looking for other information on IRS's
Web site. As a result, the ETLA feature was used significantly less this year than last. In 2004, taxpayers and practitioners submitted about 90,000 tax law and procedural questions via the Web site, down from 153,000 in 2003, a 41 percent decrease. IRS officials have decided not to move the ETLA feature to a more prominent
location as of October 2004.

Although the number of questions received from taxpayers via the Web site
is small, when compared to the number of questions received over the telephone, providing accurate responses to these questions is particularly
important. Not only do inaccurate and untimely responses disappoint the taxpayers asking the questions, IRS also runs the risk of widespread dissemination of inaccurate email responses to other taxpayers.

The decisions about the prominence of the feature and
staffing are related. Achieving timeliness and accuracy goals depends, in part, on recognizing that decisions about the prominence of the feature, which affect taxpayer demand, and decisions about staffing are related. If IRS is unwilling to
devote significant staff to answering tax law questions, then the feature cannot be prominent on the Web site. If IRS believes the feature is worth making prominent, then there are implications for staffing. For the 2004 filing season, IRS's decisions failed to recognize the relationship.

IRS Continues to Offer New Web Services

IRS continued to offer new services via its Web site. New services are popular with taxpayers, as shown by the increasing use of features, such as
"Where's My Refund?" shown in table 2. In 2004, IRS added the following customer service features for taxpayers and tax practitioners.

o
"Remember Your Advanced Child Tax Credit" that allows taxpayers to check the amount of their child tax credit.

o "EServices" which is a suite of Internet services for tax practitioners
that is previously discussed in the processing section of this report.

Conclusions IRS improved its filing season performance this year compared to last.
More importantly, in many areas the improved performance is part of a trend that IRS is sustaining over time. IRS's filing season performance is
important because it affects over 100 million taxpayers. Taxpayers want a quick turnaround on their refunds; they want easy access to IRS's
telephone assistors if they have questions; and they want to instantly
download forms and publications when they need them.

The improvements we found are the result of systematic, longterm efforts by IRS. Processing results have improved and resources have been saved because of IRS's promotion of electronic filing, telephone access has improved
because IRS implemented new call routing technology, and laborintensive walkin assistance is decreasing because of improvements to
alternative services. IRS should be commended for its efforts to improve service.

At the same time, however, we have identified several areas that present opportunities for further improvement. IRS has limited performance measures and data with which to assess the quality of services at walkin
and volunteer sites, primarily because its initiatives for doing so are only partially implemented. IRS deserves credit for planning initiatives to
address these data limitations. However, we are concerned that until the
walkin initiative is fully implemented, IRS will have biased quality data on walkin service. Furthermore, the history of delays and incomplete plans for the walkin and volunteer site initiatives leaves us unsure about when IRS will fully implement them. Until IRS fully implements
these initiatives
and gathers data on quality, it may not be able to effectively monitor and improve performance at its walkin sites or volunteer sites and, as a consequence, could be risking its credibility among taxpayers who use the

sites and the communitybased coalitions that prepare returns
at volunteer sites.

Finally, IRS failed to meet its goals for accuracy and timeliness of email
responses to tax law questions, at least in
part, by failing to match taxpayer
demand for the feature with staffing. The risk associated with providing
inaccurate email responses may be high because of the potential for widespread dissemination.

Recommendations To address problems with the data for assessing the quality of services at
IRS walkin and volunteer sites, we recommend that the Commissioner of Internal Revenue direct the appropriate officials to

o recognize and disclose the limitations of the Embedded Quality
performance data that will be obtained by direct management
observation in 2005 when interpreting and reporting on service quality at walkin sites;

o
ensure that the causes of delays in implementing improved quality measurement at walkin sites are addressed; and

o
ensure that the delays with the development and implementation of the Quality Assurance initiative at volunteer sites are addressed.

With respect to the Web site's ETLA feature, we recommend that the Commissioner

o
recognize that decisions about the prominence and staffing to give the feature are related.

Agency Comments and Our Evaluation

The Commissioner of Internal Revenue provided written comments in a November 8, 2004, letter (see app. III). The Commissioner noted that the 2004 filing season was one of the best ever, with improved telephone service, timely and effective return processing, substantial increases in
electronic filing, and a successful shift in the number of tax returns prepared in IRS walkin sites to volunteer sites. The Commissioner said he appreciated that our report recognized IRS's achievements for this filing season and over the past few years as well.

The Commissioner agreed with the importance of recognizing and disclosing the limitations of performance data obtained by managers directly observing employees in 2005. He also said that IRS has
communicated the limitations in briefings with all levels of management and outside stakeholders, and will continue to do so. However, the Commissioner differs with our assessment of the extent of the limitations
in the data. While he agreed that there may be some bias in the data because employees know that their managers are observing them, he disagreed with our subsequent finding that data obtained through this
method may not be representative of true performance. However, as our
report indicates, because of the potential for bias and absence of other
data, we cannot determine if the observed performance is representative or
not. Further, according to IRS officials, the accuracy rates compiled by the quality review staff and managerial reviews cited by the Commissioner are not based on statistically representative samples.

The Commissioner agreed with the recommendation to ensure that causes
of delays in implementing improved quality measurement at walkin sites
are addressed. He said that while the delay in the implementation of
contact recording as a means of collecting embedded quality data is
attributable to the lengthy approval process, IRS expects to begin the contact recording pilot by January 2005 and is
on target for postpilot initial
implementation for the last quarter of fiscal year 2005. Regarding volunteer sites, the Commissioner also agreed with the recommendation to implement quality initiatives in a timely manner and address delays.

The Commissioner agreed with the intent of our recommendation about the ETLA feature, but disagreed with our assessment of the cause. He agreed that it is important to recognize the relationship between the
prominence of the feature and staffing, but disagreed that the decline in
ETLA performance is attributable to inadequate recognition of this
relationship. He stated that the ETLA feature was inadvertently placed in a
more prominent location on IRS's Web site, thus creating unexpected
demand. However, inadvertent placement suggests that the IRS needs to be more deliberative in recognizing the impact that placement of this feature can have on demand and staffing.

Data on IRS's Processing Performance Relative to Fiscal Year 20012003 Performance and Fiscal Year 2004 Goals

As table 3 shows, the Internal Revenue Service (IRS) nearly met or
exceeded seven out of the eight processing performance goals in 2004. For
four measures (i.e., deposit error rate, deposit timeliness, refund interest
paid, and productivity), IRS exceeded its goals. For two of the measures, IRS met their goals. For the remaining two, IRS missed its goals by a statistically significant amount. In the case of
refund timeliness, however,
the point estimate of 98.2 percent, nearly met the goal of 98.4 percent. In the case of letter error rate, the point estimate was 7 percent compared to
the goal of 6.2 percent-13 percent greater than the 2004 goal.

Comparing actual 2004 performance to 2003 shows that IRS's performance improved or remained about the same
for six out of the seven measures that could be compared. Table 3 also shows that IRS's processing performance in 2004 has generally improved in comparison to 2002 and 2001 for the measures that could be compared.

a The measures for fiscal year 2004 are through July 31, which were the
latest data available at the time we ended our audit work. According to
IRS officials, the 2004 results through July 31 are reflective of IRS's
performance during the filing season. In addition, IRS officials told us
that the results for the measures should not change significantly through
September 30.

b According to IRS officials, they did not compute a margin of error for
these measures in 2001.

c Systemic errors are computer-generated errors over which a particular
processing center would have no control.

d IRS estimates these measures to have a 90 percent confidence interval.

e IRS's measure for Deposit timeliness for 2004 was not comparable to
previous years because IRS changed the formula to not include weekends in
calculating timeliness.

Appendix II

IRS Spends Thousands of Staff Years on Filing Season Activities

IRS's performance during the filing season has significant budgetary
implications because IRS spends thousands of staff years on its key filing
season activities.1

Table 4 shows IRS has significantly decreased the number of staff years2
used for key activities related to processing individual tax returns
between fiscal years 1999 and 2003.3 The number of staff years used for
key processing activities such as data transcription and correcting errors
has decreased over 17 percent during this period.4 Beginning in fiscal
year 2001, IRS separated the processing of individual and business tax
returns and began consolidating paper processing centers. IRS officials
expect additional savings when it further consolidates processing paper
operations in Memphis, Tennessee in 2005.

1 The source of data for this appendix is IRS's time and attendance
systems, the output of which is used to calculate IRS's payroll expenses.
IRS reports these payroll expenses annually in its Statement of Net Cost,
the reliability of which GAO tests as part of our audits of IRS's
financial statements. These audits have concluded that for the fiscal
years ended September 30, 2000 through 2003, IRS's Statement of Net Cost
was reliable. See GAO, Financial Audit: IRS's Fiscal Years 2004 and 2003
Financial Statements, GAO-05-103 (Washington, D.C.: Nov. 10, 2004).
Therefore, the data is likely to be reliable to show trends over time.

2 Staff years and Full-Time Equivalents are units of measurement that are
often used interchangeably. According to IRS, a Full-Time Equivalent is
the equivalent of one person working full-time for one year with no
overtime. A staff year includes overtime. Therefore, the cost of one staff
year is equal to the cost of one Full-Time Equivalent plus overtime.

3 On a larger scale, we have previously reported that IRS spent about
14,065 Full-Time Equivalents for all submission-processing activities and
operations (i.e., both individual and business income tax returns and
other correspondence work outside of processing returns) in fiscal year
2003 or about 14 percent of its entire 98,381 Full-Time Equivalent
allocation. This was down over 1,000 Full-Time Equivalents or 1 percent
from around 15,101 Full-Time Equivalents used in fiscal year 2002. See
GAO-04-560T and GAO, Internal Revenue Service: Assessment of Fiscal Year
2004 Budget Request and 2003 Filing Season Performance to Date,
GAO-03-641T (Washington, D.C.: Apr. 2003).

4 According to IRS officials, the decrease in staff years for electronic
filing is due to the reduction of documents required by IRS to be filed on
paper. For example, power of attorney forms can now be filed
electronically.

Activities

However, the time IRS spent directly on return preparation assistance at
walkin sites during the filing season has decreased significantly. As the demand for walkin assistance has declined, IRS has assigned walkin staff
other responsibilities such as working on compliance cases. Figure 7 shows that direct FullTime Equivalents6 decreased 62 percent for time
spent directly (not counting overhead) on return preparation services between 2001 and 2004.

At the same time, IRS reduced its reliance on compliance staff at walkin sites. For years, IRS detailed staff from its compliance functions, such as
Examination and Collection, to help provide walkin assistance during the filing season. IRS has now limited the number of such details. IRS reduced the number of compliance FullTime Equivalents detailed to assist at walkin sites from 244 in the 2001 filing season to 9 in the 2004 filing season.
