MEMORANDUM FOR COMMISSIONER, INTERNAL REVENUE SERVICE
FROM: Michael R. Phillips /s/ Michael R. Phillips
Deputy Inspector General for Audit
SUBJECT: Final Audit Report –The Strategic Improvement Themes in the Taxpayer Assistance Blueprint Phase I Report Appear to Be Sound; However, There Were Some Inaccurate Data in the Report (Audit # 200740012)
This report presents the results of our review to assess the accuracy and reliability of the
data used to develop the Taxpayer Assistance Blueprint (TAB) Phase I report.
Impact on the Taxpayer
In July 2005, Congress issued a
report requesting that the Internal Revenue Service (IRS) develop a 5-year plan
including an outline of which services the IRS should provide and how it will
improve services for taxpayers. The conclusions and
strategic improvement themes outlined in the TAB Phase I report were valid;
however, not all information included in the Phase I report was accurate and/or
consistent. As the IRS moves forward with
its 5‑year service delivery plan, inaccuracies and/or inconsistencies will
put the plan at risk of improperly aligning service content, delivery, and
resources with taxpayer and partner expectations.
Synopsis
The focus of the TAB
initiative is on services that support the needs of individual filers who file
or should file Form 1040 series tax returns.[1] The IRS indicates the initiative will address
the challenges of effectively and efficiently aligning service content,
delivery, and resources with taxpayer and partner expectations.
Management stated
they have improved the process for validating information in the TAB Phase II
report
To satisfy the
report submission date of April 14, 2006, the IRS designed the TAB as a two‑phased
process. The TAB Phase I report identified
strategic improvement themes by researching IRS service relative to taxpayers’
needs and preferences. The TAB Phase II report
will validate the strategic improvement themes through further research of taxpayers’
service preferences and develop the 5-year plan for service delivery.
The majority of the information
reviewed was accurate. Information found
to be inaccurate and inconsistent did not affect the IRS’ strategic improvement
themes. Moreover, the five strategic improvement
themes are common to organizations that aspire to deliver successful customer
service.
In general,
the TAB Phase I report was well documented and accurate; however, there were
some inconsistencies and inaccuracies which we brought to management’s
attention.
In the TAB Phase I
report, the IRS cited 173 data sources, which included surveys, studies,
analyses of Form 1040 series tax return data, and discussions with
internal and external stakeholders. The
documentation for the data sources was well organized and easily
accessible. A sample of 56 (27 included
in the body of the report and 29 listed in the Reference Appendix) of the 173
data sources showed documentation was adequately
maintained for all 56 data sources.
Ninety-five percent (55 of 58) of the statements reviewed (29 from
the report’s Reference Appendix and 29 statements sampled from the report
text) were found to be accurate. However,
the types of problems we found with the compilation of some of the data could
adversely affect IRS management decisions.
For example, we found inaccuracies in the report related to changes in
If these inconsistencies exist in the Phase II report, the risk
increases that the IRS will draw inaccurate conclusions based on erroneous
data. We are unable to determine the
impact the inconsistencies may have on results outlined in the TAB Phase II
report because it was not available for review.
The IRS would not provide us with a copy of the report before it was
officially issued. The TAB Phase II
report was issued the week of April 9, 2007, after completion of this review,
and we have now begun our review to evaluate it.
The inaccuracies and
inconsistencies resulted primarily from the IRS not having an effective process
to ensure all statements in the TAB Phase I report correctly reflected the
results of its research and data analyses.
We shared our results with management throughout the course of our
review. They recognize the need to
improve their quality assurance process.
Management officials stated that actions have been taken to improve the
process for the validation of information included in the TAB Phase II
report. This process includes an indepth
review to locate and verify the accuracy of all footnoted citations, reference
documents, and data points contained in all charts and tables in the
report. Verifications were also
performed to ensure the accuracy of statements and representations included in
the report. Therefore, we are not making
recommendations at this time but will include testing of the quality review
process in our review of the TAB Phase II report.
Response
IRS management indicated that prior to the completion of this report, a thorough quality review process was developed and implemented for the TAB Phase II. Experienced analysts validated information in the TAB Phase II report, including all citations, reference documents, and data presented in the report. This process was thoroughly documented, and the IRS believes the result is an accurate and well-documented TAB Phase II report. Management’s complete response to the draft report is included as Appendix V.

Taxpayer Assistance Blueprint |
In May 2005, the Internal Revenue Service (IRS) announced plans to close a portion of its Taxpayer Assistance Centers[2] as part of the agency’s continuing efforts to create efficiencies, modernize operations, and reduce costs while maintaining its commitment to taxpayer service. Congress expressed concern about the proposed taxpayer service reductions due to the IRS’ inability to explain the potential impact of these changes on taxpayers. Congress was also concerned that the proposed service cuts lacked specificity and the IRS had not developed concrete plans to provide adequate alternative services that would replace the proposed service cuts. Finally, Congress questioned the IRS’ estimated cost savings from reducing some of its services.
In July 2005, Congress issued a report requesting that the IRS develop a 5-year plan for taxpayer service activities[3] and in November 2005 requested the IRS report to the House and Senate subcommittees by April 14, 2006. The plan was to include long-term goals that are strategic and quantitative and that balance enforcement and service.[4] The Senate Committee Report stated the plan should outline the services the IRS should provide to improve service to taxpayers. The plan was also to detail how the IRS plans to meet the service needs on a geographic basis and address how the plan would improve taxpayer service based on reliable data on taxpayer service needs. The plan was to be developed with the IRS Oversight Board[5] and the National Taxpayer Advocate.
The focus of the Taxpayer Assistance Blueprint (TAB) initiative is on services that support the needs of individual filers who file or should file Form 1040 series tax returns.[6] The IRS indicates the initiative will address the challenges of effectively and efficiently aligning service content, delivery, and resources with taxpayer and partner[7] expectations.
To satisfy the report submission date of April 14, 2006, the IRS designed the TAB as a two‑phased process. The TAB Phase I report identified strategic improvement themes by researching IRS service relative to taxpayers’ needs and preferences. The TAB Phase II report will validate those themes through further research of taxpayers’ service preferences and will develop the 5-year plan for service delivery. The 2006 TAB Phase I report, issued April 24, 2006, presented five strategic improvement themes. Figure 1 list these themes and Appendix IV provides details of each theme.

The themes were based upon:
· Current baseline of taxpayer services.
· Preliminary understanding of taxpayers’ needs and preferences based on primary research (collected through surveys, focus groups, and interviews with stakeholders, employees, and partners and secondary research gathered through studies, research reports, and literature reviews)
· Targeted research and analyses of customer insights from external organizations.
TAB Phase II will build on the strategic improvement themes and will produce a 5-year plan for preferred service delivery to individual taxpayers within available resources. The themes will be refined and validated in the TAB Phase II. The resulting 5-year plan will describe the evolution of taxpayer services over the next 5 years, with specific and measurable operational goals. The IRS originally planned to deliver the TAB Phase II report to Congress in December 2006.
The IRS would not provide the Treasury Inspector General for Tax Administration with a copy of the report before it was officially issued. The TAB Phase II report was issued the week of April 9, 2007, after completion of this review, and we have now begun our review to evaluate it.
This review
was performed at the IRS Wage and Investment Division, Customer Assistance,
Relationships, and Education Office and the Strategy and Finance, Research
Office located in
The Taxpayer Assistance Blueprint Phase I Report Was Well Documented, but Some Information Included in the Report Was Not Accurate or Consistent
The Government Accountability Office stresses[8] significant events need clear documentation that should be readily available for examination. The data used to prepare the TAB Phase I report was well documented, organized, and maintained. The majority of the information reviewed was accurate. Information found to be inaccurate and inconsistent did not affect the IRS’ strategic improvement themes. This is because the five strategic improvement themes are common to organizations that aspire to deliver successful customer service. Therefore, the erroneous information was not needed to support the resulting five themes.
IRS officials stated that most of the data developed and used in the Phase I report were for perspective. They estimate the Phase I report contains only 20 percent of the data used in developing the TAB Phase II report, which had not been finalized or approved during this portion of our review. Consequently, we could not evaluate what impact any errors might have on the Phase II report. We have begun evaluating the TAB Phase II report.
The IRS originally planned to deliver the TAB Phase II report to Congress in December 2006. IRS officials stated the Senate Finance Committee staff was pleased with the April delivery of the Phase I report. The staff also stressed they wanted the IRS to take the time necessary to deliver the Phase II report to ensure the report is what Congress wanted the IRS to deliver.
Although the errors identified did not affect the conclusions of the TAB Phase I report, these types of problems with the compilation of data could adversely affect IRS management decisions. As the IRS moves forward with the development of a 5-year service delivery plan, inaccuracies and/or inconsistencies will put the IRS’ plan at risk of improperly aligning service content, delivery, and resources with taxpayer and partner expectations.
The IRS maintained the documentation
to support data sources cited in the TAB Phase I report
In the TAB Phase I report, the IRS cited 173 data sources that included surveys, studies, analyses of Form 1040 series tax return data, and discussions with internal and external stakeholders. The documentation for the data sources was well organized and easily accessible.
A sample of 56 (27 included in the body of the report and 29 listed in the report’s Reference Appendix) of the 173 data sources showed documentation was adequately maintained for all 56 data sources. We conducted further testing for the 29 data sources listed in the Phase I report’s Reference Appendix and confirmed the data sources were used to support information in the report.
Some information in the TAB
Phase I report was inaccurate or inconsistent
Ninety-five percent (55 of 58) of the statements reviewed (29 from the report’s Reference Appendix and 29 statements sampled from the report text) were found to be accurate. However, some statements were inaccurate and the IRS did not ensure consistency between income and generational analyses and conclusions. The inaccuracies and inconsistencies were associated with information detailed in the Current Taxpayer Services, Taxpayer Understanding, and Leading Practices sections of the TAB Phase I report.
· The Current Taxpayer Services section provides an overview of the current taxpayer services and a snapshot of volume patterns of key service delivery channels.
· The Taxpayer Understanding section provides a comprehensive overview of the IRS customers’ expectations for services.
· The Leading Practices section provides customer service practices gathered through research and analyses of government agencies, non-profit organizations, and private sector companies.
The information included in these three sections of the TAB Phase I report was provided for perspective only. Although in most instances the documentation and/or analyses were accurate, statements in the Phase I report were incorrect. Since business decisions are expected to be made from the Phase II report, and the report establishes the IRS’ 5‑year plan to improve taxpayer service, it is essential that all statements and conclusions in the Phase I report are accurate.
Inaccurate
statements
Three statements were found to be inaccurate, though the conclusions drawn from the statements were mostly accurate.
·
The report
states that since Fiscal Year 2003, the number of telephone calls answered has
decreased by more than 18 million (19 percent) and Taxpayer Assistance Center visits
have decreased by almost 300 thousand (9 percent). Supporting documentation shows that the
decrease in the number of telephone calls was more than 20.8 million, a 26
percent decrease, and the decrease in
The report states that the senior[9]
and baby boomer[10]
generations comprise approximately 60 percent of the United States population. Supporting documentation shows 50 percent of the United States population in 2000 was
seniors and baby boomers and decreases to 45 percent in 2005.
·
The report
states that survey results from the 2005 IRS Oversight Board Taxpayer Attitude
Survey revealed 78 percent of the taxpayers surveyed were satisfied with the
levels of service they receive over the telephone. However, the survey question asked
respondents how important it was that the
IRS provides each of the following services to assist taxpayers.
·
A toll-free telephone number to answer your
questions.
·
Office locations you can visit where an IRS
representative will answer your questions.
·
A web site to provide you with information.
·
The ability to e-mail your questions directly
to the IRS.
Seventy-eight percent of the respondents indicated it was very important that a toll-free number was provided, not that they were satisfied with the service they received.
Inconsistent use of income and generational segmentation
To better understand the expectations of a broad taxpayer base, the IRS segmented the population using two differentiating factors – income and age by generations. The IRS stated that similar to the process used by leading financial organizations, segmenting by income affords important insights into commonalities and differences across income groupings. Research indicates that generational segmentation also offers important insights into behaviors, specifically in four areas the IRS believes remain relatively stable. These four areas are (1) communication preference; (2) information seeking behavior; (3) attitudes toward government, commerce, and finance; and (4) technology base. Figure 2 outlines how the IRS defined the income and generational segmentation.

The IRS was not consistent in its use of income segmentation. Figure 3 shows the differences identified in the report between the volume of taxpayers based on the Taxpayer Segmentation Framework and the volume of taxpayers shown in the graphs. The volume of taxpayers in the graphs have been overstated for the Moderate Income taxpayers and understated for the Moderately High Income taxpayers. The IRS indicated the analyses supporting the graphs included the correct income segmentation. However, the income ranges detailed in the graphs were mislabeled.

In addition, age ranges used for an analyses conducted to identify preferences based on generational segmentation were not consistent with those defined by the IRS and its Taxpayer Segmentation Framework. Specifically, the age ranges used to identify the preference of older and younger taxpayers categorized Millennials as ages 18 to 29 years, Generation X as ages 30 to 44 years, Baby Boomers as ages 45 to 59 years, and Seniors as ages 60 years and older. However, the Taxpayer Segmentation Framework classified Millennial as ages 0 to 29 years, Generation X as ages 30 to 40 years, Baby Boomers as ages 41 to 60 years, and Seniors as ages 61 to 116 years. As a result, the age segmentations are overstated or understated. For example, the volume of Generation X taxpayers is overstated by 39 percent, or approximately 10 million taxpayers, and the volume of Baby Boomers is understated by 26 percent, or approximately 12 million taxpayers.
Figure 4 provides a comparison of the volume of taxpayers when segmenting using age ranges found in the Taxpayer Segmentation Framework and when segmenting using age ranges used by the IRS when performing the generational analyses.

analyses of the generational study compared to the Taxpayer Segmentation
Framework.
IRS management stated the inconsistent generational segmentation happened because of the short time period they had to deliver the Phase I report. The contractor the IRS used to perform the generational segmentation analyses used an existing panel of individuals to survey. This existing panel was not segmented into the same generational segments as in the TAB Phase I report.
The inconsistencies relating to income and generational segmentation have no impact on the strategic improvement themes outlined in the TAB Phase I report. However, we are unable to determine the impact the inconsistent income and age segmentation may have on results outlined in the TAB Phase II report because it was not available for review. If these inconsistencies exist in the Phase II report, the risk increases that the IRS will draw inaccurate conclusions based on erroneous data. We plan to initiate an audit of the TAB Phase II report once it has been issued.
Lack of validation of the information in the
report
The inaccuracies and inconsistencies identified resulted primarily from the IRS not having an effective process to ensure all statements in the TAB Phase I report correctly reflected what was in the source documents. The IRS stated an extensive quality assurance process was used to validate the Phase I research. The IRS explained that the review process ensured research products were continuously subjected to rigorous peer, senior management, and executive review. However, there was no step in the process to ensure what was written in the report agreed with the research and data analyses. Without an improved quality assurance process, the risk increases that decisions the IRS makes on its 5-year plan to improve taxpayer service will be based on inaccurate data.
The Government
Performance and Results Act of 1993[14] directs Federal Government agencies
to focus on their missions and goals, how to achieve them, and how to improve
their structural organizations and business processes. Performance measures need to be based on
program-related characteristics and performance data and must be sufficiently
complete, accurate, and consistent.
Performance data must be used to improve organizational processes,
identify performance gaps, and set improvement goals.
We shared our results with management throughout the course of our review. They recognize the need to improve their quality assurance process. Management officials stated that actions have been taken to improve the process for the validation of information included in the Phase II report. This process includes an indepth review to locate and verify the accuracy of all footnoted citations, reference documents, and data points contained in all charts and tables in the report. Verifications were also performed to ensure the accuracy of statements and representations included in the report. We are not making recommendations at this time but we will include testing of the quality review process in our review of the TAB Phase II report.
Appendix I
Detailed Objective, Scope, and Methodology
Our overall objective was to assess the accuracy and reliability of the data used to develop the TAB
Phase I report. Because we did not have
the resources to test all statements and validate all data in the report, we
consulted a statistician to determine the best methodology to use for our
testing. To accomplish this objective,
we:
I. Determined the process followed for developing the Phase I report.
II. Determined whether the IRS had documentation supporting data sources cited in the TAB Phase I report.
A. Identified 55 data sources cited in the TAB Phase I report.
B.
Based
on a statistician’s recommendations, we used a random sample and selected 27 data
sources.
1. We chose a sample size of approximately 30 data sources and used a random number to make the selection. We divided the number of references, 55, by 30 resulting in the number 1.833. We rounded it to 2.
2. We used an interval selection by selecting every second source starting with the number 2, resulting in a random sample of 27. The final sample ended at number 54 and because there was no second sample beyond 55, we concluded with a sample of 27.
C. Reviewed the supporting document to ensure the source cited in the report was the same as the source provided by the IRS.
III. Determined whether the data sources cited in the TAB Phase I Reference Appendix were used to support information included in the Phase I report and whether the IRS had documentation supporting these data sources.
A. Identified 118 data sources cited in the Reference Appendix.
B.
Based
on a statistician’s recommendations, we used a random sample and selected 29 data
sources from the report’s Reference Appendix.
1. We chose a sample size of approximately 30 data sources and used a random number to make the selection. We divided the number of references, 118, by 30 resulting in the number 3.933. We rounded the number to 4.
2. We used an interval selection by selecting every 4th reference starting with the number 4, resulting in a random sample of 29. The final sample ended at number 116 and because there was no fourth sample beyond 118, we concluded with a sample of 29.
C. Once we found support for the statement, we determined whether the support contained evidence that supported the report and whether the information cited was accurate.
IV. Determined the accuracy of the statements used in the TAB Phase I report.
A.
Reviewed the Phase I report and identified key
assumptions and conclusions cited in the report.
B.
Based on a statistician’s recommendations, we
used a stratified sample.
1.
We listed all 124 assumptions from the Phase I report,
under the headings of Taxpayer
Understanding and Leading Practice.
2.
We met as a team and determined which assumptions we believed
would have the most impact on the results.
3. We determined that 29 statements warranted review and determined whether the assumptions could be supported.
C. Once we found support for the statement, we determined whether the support contained evidence that supported the report.
