The
Challenges of Transparency in Corporate Tax Departments
What Will the New Audit Documentation Requirements
and FIN 48 Reveal to the IRS?
By Mark
J. Cowan and Tom English
OCTOBER 2007 - In the wake of the accounting
scandals of recent years, standards-setters have aspired to improve
financial reporting documentation and transparency. In particular,
recent guidance with respect to section 103 of the Sarbanes-Oxley
Act (SOX), “Auditing, Quality Control, and Independence Standards
and Rules,” and FASB Interpretation (FIN) 48, Accounting
for Uncertainty in Income Taxes, has put pressure on companies
and their auditors to better articulate tax risks and exposures.
At the same time, the IRS appears to be getting more aggressive
in seeking access to tax accrual workpapers. The confluence
of these trends puts in-house corporate tax departments in a very
difficult position. First, already overburdened tax departments
will have to rise to the challenge of complying with the new documentation
requirements. Second, the tax accrual workpapers, particularly
with regard to tax exposures, must now be more detailed than ever.
Should the IRS gain access to such workpapers, a company’s
tax “secrets,” including aggressive tax positions
and other tax “soft spots,” would be revealed. This
disclosure would give the IRS the upper hand in audits and put
corporate tax managers at a significant disadvantage.
What follows is a review of the efforts by accounting and auditing
authoritative bodies to enhance documentation in the tax function,
including the consolidated impact of guidance issued with respect
to SOX section 103 and FIN 48; a discussion of how tax departments
can cope with these new requirements; and an assessment of the
risk posed by these new requirements in light of IRS policies
on workpaper access.
Increased Audit Documentation Requirements
Historically, auditing rules for all companies were issued by
the Auditing Standards Board (ASB), a private technical group
created by the AICPA. Section 101 of SOX created the Public Company
Accounting Oversight Board (PCAOB), a new private-sector, nonprofit
corporation vested with the authority to issue auditing standards
for companies that report to the SEC. Audits of companies that
do not report to the SEC continue to be governed by the ASB’s
standards.
The PCAOB issued Auditing Standard 3 (AS3), Audit Documentation,
on August 25, 2004. The standard is effective for audits of financial
statements for fiscal years ending on or after November 15, 2004.
The standard was the result of SOX section 103(a)(2)(A)(i), which
required the PCAOB to establish standards regarding audit documentation.
It is one of the few specific items that SOX requires of the PCAOB,
demonstrating the significance the law places on documentation
and transparency. AS3 indicates that documentation includes “evidence
obtained, and conclusions reached by the financial statement auditor”
(para. 2). It requires the financial statement auditor to maintain
documentation that has sufficient detail to allow “an experienced
auditor, having no previous connection with the engagement to
understand the nature, timing, extent and results of procedures
performed” (para. 6) and “should include identification
of the items inspected … [and] abstracts or copies of the
documents” (para. 10). These items are to be maintained
for outside reviewers such as “external inspection teams
that review documentation to assess audit quality and compliance
with auditing and related professional practice standards; applicable
laws, rules and regulations” (para. 3).
Similarly, the ASB issued SAS 103, Audit Documentation
(included in the AICPA Professional Standards at AU 339), effective
for audits of all companies for fiscal years ending on or after
December 15, 2006. It states that documentation “should
include the identifying characteristics of the specific items
tested” (AU 339.20). The documentation should demonstrate
“the accountability of the audit team for its work by documenting
the procedures performed, the audit evidence examined and the
conclusions reached” (AU 339.8). Specific pieces of evidence
should be included “if they are needed to enable an experienced
auditor to understand the work performed and conclusions reached”
(AU 339.6). If transferring a paper copy to another medium, “the
auditor should apply procedures to generate a copy that is faithful
in form and content to the original paper document” (AU
339.5).
While the above PCAOB and ASB standards are of recent vintage,
financial statement auditors were already following similar procedures
in practice up until the mid-1990s. In the 1990s, auditors began
to stray from this detailed approach to documentation toward a
more general policy in an effort to provide less detail for plaintiffs’
attorneys and to streamline audit files (e.g., auditors stopped
identifying the specific invoices that had been tested). Compliance
with these increased documentation requirements will return financial
statement auditors’ documentation to pre-1990s levels and
place greater demands on auditors and their clients. Audit files
will have more detail about a client’s tax position, including
potential tax exposures.
FIN 48
FASB issued FIN 48, Accounting for Uncertainty in Income
Taxes, on June 13, 2006. FIN 48 interprets SFAS 109, Accounting
for Income Taxes. FIN 48 is effective for fiscal years beginning
after December 15, 2006. Once adopted, FIN 48 applies to all tax
return positions taken by the company, including tax returns filed
in prior years (para. 23). A full technical discussion of FIN
48 is beyond the scope of this article, but a detailed analysis
can be found in Neil D. Kimmelfield, et al, “Accounting
for Uncertainty in Income Taxes—The Effect of FASB Interpretation
No. 48,” The Tax Executive, July–August 2006.
FIN 48 could represent a sea change in the way that companies
report income taxes on their financial statements. While the basic
framework of SFAS 109 remains the same, companies must meet a
new threshold before they can report tax benefits on their financial
statements. Under SFAS 109, companies would estimate the amount
that would be reported on their income tax returns in current
and future years and use that as a basis to report their current
and deferred liabilities or assets. Diverse methods were then
used to account for any additional tax that could become due because
of aggressive tax positions. (See FIN 48, para. B2.)
While practice varied, many companies would use SFAS 5, Accounting
for Contingencies, to determine whether a liability should
be established for aggressive tax positions. Under the SFAS 5
approach, a liability had to be established only if it was “probable”
that the company would owe additional tax as of the balance sheet
date and such amount could be reasonably estimated. “Probable”
means likely—generally a likelihood that is less than 100%
but greater than 50%. In practice, most viewed an event as probable
if it had a 75% or greater likelihood of occurrence. Larger companies
that were regularly audited by the tax authorities would do an
analysis showing their major exposure items and their chances
of success with each. Corporate tax managers would then ensure
that they maintained an additional tax liability at least equal
to the added tax they would probably need to pay. Most companies
would also provide for additional amounts, establishing a cushion
against any unexpected fluctuations in their tax expense. Smaller
companies that were not regularly audited by the tax authorities
would often not do a detailed review of their tax exposure items.
Under FIN 48, SFAS 5 can no longer be used. Instead, tax benefits
claimed (or to be claimed) on a tax return may only be recorded
on the financial statements if it is “more likely than not”
(a likelihood of more than 50%) that such benefits would be sustained
on examination by the tax authorities or ultimately in court.
This approach is the opposite of SFAS 5, under which a benefit
claimed on a tax return was also generally claimed on the financial
statement unless it was probable it would not be sustained on
audit. Thus, unless the tax benefit was likely to be lost on audit,
it was generally recorded. (For further detail on SFAS 5 analyses
and pre–FIN 48 alternative views as to the proper recognition
of tax benefits, see James R. Browne, “Financial Reporting
for Uncertain Tax Positions,” Tax Notes, October
3, 2005.) Under FIN 48, a benefit cannot be claimed at all unless
there is a more than 50% likelihood that it would be sustained
on audit or in court.
In other words, under SFAS 5, a company generally reported a
tax benefit unless it could establish that it had an approximately
75% chance of losing if the benefit was challenged (i.e.,
only a 25% chance of winning). Under FIN 48, a company reports
no tax benefit unless it can establish it has a greater than 50%
chance of winning if the benefit is challenged. In applying
FIN 48, it is presumed that the position would be examined by
the relevant tax authority and that such authority would have
knowledge of the relevant facts (para. 7a).
Furthermore, per FIN 48 (para. 21), companies must annually disclose
the gross amounts of unrecognized tax benefits and increases or
decreases in the amounts during the year. The disclosures must
include, in gross, the increases or decreases resulting from positions
taken during current and prior years, settlements with tax authorities,
and changes resulting from the closing of statutes of limitations.
Even though this information will be provided in gross, it will
provide more detail to investors and the tax authorities than
in the past. (For an example of the presentation of these new
disclosures, see FIN 48, para. A33.)
Under FIN 48, companies will need to apply more scrutiny to their
tax positions than ever before. Smaller companies that are not
regularly audited by the tax authorities, and thus did not worry
about setting up a reserve for tax positions under SFAS 5, will
be forced to critically evaluate their tax positions and exposures
in detail—perhaps for the first time. (For further discussion
of this issue, see William L. Raby and Burgess J.W. Raby, “Quantifying
Uncertain Tax Positions,” Tax Notes Today, October
11, 2006.)
Larger companies that have historically performed an SFAS 5 analysis
will need to apply even more scrutiny to document that their tax
positions are more likely than not to be sustained. Because of
the prior diversity in accounting for uncertain tax positions,
the adoption of FIN 48 will affect companies in different ways.
Some companies that used the SFAS 5 approach may see their tax
liabilities increased upon adoption of FIN 48. Other companies
may have, in the past, erred on the side of conservatism in recording
tax benefits. Such companies may see their tax liabilities decrease
upon adoption of FIN 48. (For a summary of some early FIN 48 disclosures,
see, for example, Thomas Jaworski, “Tax Disclosures Week
in Review: Time Warner, Others Foresee Sizable Effects from FIN
48,” Financial Reporting Watch, February 23, 2007.)
FIN 48 is likely to affect tax planning as well. Management is
often concerned with whether the tax benefits resulting from proposed
tax planning ideas can be recorded on the financial statements.
Corporate tax departments will now need to run potential tax planning
ideas or transactions through a FIN 48 analysis to determine the
financial statement impact. This should be done when the transactions
are being planned, in order to give management advanced warning
of tax benefits that may not be recordable under FIN 48.
Consolidated Impact of AS3, SAS 103, and FIN 48
To support recognition under FIN 48’s “more likely
than not” standard, a company must accumulate evidence to
support its tax positions. FIN 48 (para. 5) indicates that the
amount and type of evidence required are matters of judgment based
on the particular facts and circumstances of the position. FIN
48 (para. B34) makes it clear that external legal tax opinions
can serve as evidence that the more-likely-than not standard has
been met, but such opinions are not necessarily required. In any
case, evidence of some kind must be gathered and documented in
order to conform to FIN 48 and SFAS 109. Presumably, this may
take the form of legal memos prepared by a company’s tax
department analyzing the facts and applicable tax law of various
tax positions.
External auditors are likely to demand a substantial amount of
evidence to support a company’s FIN 48 analysis. First,
there will be uncertainty regarding how much evidence is required,
given that FIN 48 allows for judgment in this area. Auditors will
likely err on the side of requesting too much, rather than too
little, support. Second, an auditor’s exposure has changed
under FIN 48. Previously, when tax uncertainties were governed
by SFAS 5, the auditor opined on a negative assertion: that the
company did not have any unreserved tax exposures where it was
probable additional tax would be due. Under FIN 48, the auditor
is opining on a positive assertion: that the tax positions reported
on the financial statements are more likely than not to be sustained.
The auditor is put at a greater risk under FIN 48 and will therefore
have a strong interest in obtaining substantial evidence to support
the client’s assertion.
Once auditors have obtained the evidence, they must review it
and, under the PCAOB and ASB standards previously discussed, document
their review of this evidence. This documentation must be detailed
enough to allow an audit professional with no prior involvement
in the audit to determine, upon review of the workpapers, what
audit work was performed, and assess the outcome of such work.
Given the complexities of FIN 48 and the rigor of the new PCAOB
and ASB documentation standards, it is likely that auditors will
want to retain substantial documentation regarding the tax provision,
such as legal memoranda in support of a client’s FIN 48
assertions.
In short, the confluence of AS3, SAS 103, and FIN 48 will result
in tax accrual workpapers that are more detailed and informative
than ever before. This poses two major challenges to corporate
tax departments: 1) documenting the evidence the external auditors
will demand in order to comply with FIN 48, and 2) assessing the
risk that such documentation may be obtained by the IRS.
Improving Documentation
FIN 48 and the accompanying pressure on auditors to more fully
document their work will put pressure on corporate tax departments
to better assess, articulate, and document their tax positions.
In this sense, FIN 48 adds to an already burdensome litany of
new pressures on corporate tax departments.
The role of the corporate tax department has shifted significantly
in recent years, and the stress of such changes has been evident.
Over the past decade, corporate tax departments have evolved from
cost centers, focused on efficiently complying with the tax law,
to profit centers, focused on reducing the company’s effective
tax rate. More recently, tax departments have had to adapt to
the changing regulatory environment. On top of their normal tax
compliance and planning functions, tax departments are now confronted
with many new requirements, including compliance with the internal
control requirements of SOX section 404, the newly expanded disclosure
of book/tax differences on Schedule M-3 of the corporate tax return,
IRS-mandated electronic filing of tax returns, and now FIN 48.
Compliance with SOX section 404 was particularly difficult for
tax departments because of documentation concerns. In fact, in
the first year of section 404 compliance, tax accounting was the
second most reported reason for internal control material weakness
disclosures. This is not surprising because, historically, tax
professionals have not been overly concerned with standardized
documentation practices. For example, many tax departments would
use ad hoc “homegrown” spreadsheets to compute tax
provisions and deferred tax amounts for year-end financial statement
reporting. These and similar documentation issues became painfully
clear as tax departments went through the first-year SOX internal
control review. (For a detailed discussion of these issues, including
best practices to address them, see Mark J. Cowan and Tom English,
“Sarbanes-Oxley Section 404 and Mandatory E-Filing,”
The CPA Journal, July 2006.)
To overcome the historic problems they have encountered in tax
accounting, tax departments will need to train their personnel
not just in the technical requirements of FIN 48, but in proper
documentation techniques as well. This is an area where the internal
audit department can help. For years, some public accounting firms
have required tax professionals to participate in one or more
financial statement audits. While some of this cross-fertilization
may have been driven by staffing needs or state CPA licensing
requirements, this effort also helped tax professionals gain an
understanding of good documentation practice. This same practice
is in place in many internal audit departments for management
trainees. Many management development programs involve rotating
management trainees through various departments, including internal
auditing. This experience provides the trainee with an overview
of the company and knowledge of good internal control practices.
In-house tax professionals could benefit from such a practice.
New hires would benefit from an internal audit stint that would
ultimately provide a pool of tax professionals with the tools
necessary to meet SOX internal control and documentation requirements
and the FIN 48 documentation that the external auditors will require.
This, of course, assumes that the tax department can spare new
hires for such an assignment. Furthermore, internal audit departments
can conduct sessions for tax professionals on documentation, or
otherwise consult with the tax department on good documentation
practice.
IRS Policy on Access to Workpapers
Once tax departments have successfully implemented FIN 48 and
external auditors have complied with the new PCAOB and ASB documentation
directives, the tax accrual workpapers will be very detailed—and
a tempting target for IRS auditors. To properly assess the risk
this scenario poses, it is necessary to understand the IRS’s
position on requesting tax accrual workpapers. “Workpapers”
can refer to both audit workpapers maintained by the external
auditor and in-house documents supporting the tax accrual. For
purposes of this discussion, any internal documents are assumed
to have been provided to the external auditors as part of their
SFAS 109/FIN 48 review. Internal documents that are not provided
to the auditors raise certain attorney-client or work-product
privilege issues beyond the scope of this article. That is, such
documents may, in certain circumstances, be entitled to greater
protection from IRS scrutiny. Given the discussion above on FIN
48 and auditor documentation requirements, however, it can safely
be assumed that the most critical and revealing documents relating
to the tax accrual have been reviewed by the auditor—and
are thus subject to the rules discussed below.
The U.S. Supreme Court, in U.S. v. Arthur Young & Co.
[465 U.S. 805 (1984)], recognized that the IRS has broad powers
to examine tax accrual workpapers. In Arthur Young, the
IRS was attempting to gain access to tax accrual workpapers prepared
by the auditors of Amerada Hess Corp. The Court noted that communications
between a taxpayer and its independent auditor were not privileged
or covered by any sort of a work-product privilege. Auditors work
for the public and, unlike attorneys, do not act as advocates
for their clients. In fact, the Court noted that making accrual
workpapers reviewed by the independent auditor confidential would
make it appear that the auditor was an advocate for the client,
weakening public confidence in the auditor’s independence
and the perceived accuracy of the financial statements.
While Arthur Young made it clear that the IRS had broad
authority to examine tax accrual workpapers, in practice the IRS
requested such workpapers only in unusual circumstances. The IRS
exercised restraint, perhaps out of fear of protests from industry
and accountants that would result if the IRS began to routinely
request tax accrual workpapers.
The restraint exercised by the IRS in the years after its victory
in Arthur Young has begun to fade. In 2002, the IRS changed
its policy and indicated that it would be more aggressive in requesting
workpapers (see IRS Announcement 2002-63, 2002-2 C.B. 72). Between
1984 (when Arthur Young was decided) and 2002, the IRS
requested tax accrual workpapers less than a dozen times. Since
2002, however, the IRS has requested tax accrual workpapers 92
times (Jesse Drucker, “Tax Battle: IRS vs. Textron,”
Wall Street Journal, June 20, 2006, quoting Deborah M.
Nolan, commissioner of the IRS Large and Mid-size Business Division.)
This acceleration in workpaper requests is largely driven by
the government’s focus on tax shelters. The IRS, much like
the PCAOB, ASB, and FASB, has been on a transparency campaign
of its own. The target of this campaign has been corporate tax
shelter activity. The detailed book/tax reconciliation in Schedule
M-3, tax shelter (so-called “listed transaction”)
disclosures, and mandatory electronic filing of corporate tax
returns are examples of IRS attempts to streamline their audits
and more readily identify aggressive tax shelter activity. Access
to detailed tax accrual workpapers would give the IRS yet another
powerful weapon in its audit arsenal.
The IRS’s current policy on requesting tax accrual workpapers
is incorporated in the Internal Revenue Manual (IRM) section 4.10.20.
The complete policy (including special rules relating to tax returns
filed prior to July 1, 2002) is available online at www.irs.gov
/irm/part4/ch10s23.html. The IRS divides the workpaper universe
into three categories and then designates policies applicable
to each one, as shown in the Exhibit.
At least for the time being, the IRS will request the tax accrual
workpapers (presumably including the new FIN 48 materials) only
if the taxpayer is engaged in a tax shelter (listed transaction
or similar transaction), or under “unusual circumstances.”
IRM 4.10.20.3.1 elaborates on the unusual circumstances standard,
indicating that the IRS should look to the taxpayer’s records
as the primary source of needed information. The tax accrual workpapers
should be requested only when the facts required for the audit
are not available from the taxpayer’s records or third parties.
Even then, only the relevant portions of the workpapers should
be requested. Any request for workpapers under the unusual-circumstances
standard must be approved by a higher-level IRS official. For
example, in the case of an audit conducted by the IRS’s
Large and Mid-size Business Division, the director of field operations
must approve the request (IRM 4.10.20.4).
Responding to taxpayer fears, IRS Chief Counsel Donald Korb indicated
that safeguards were in place to prevent the IRS from broadening
the scope of the unusual-circumstances test. Korb indicated that
the IRS’s policy was designed to discourage taxpayers from
engaging in tax shelter transactions. If the taxpayer engaged
in a tax shelter, the IRS would request the workpapers. If not,
the IRS would only request the workpapers in unusual circumstances.
If the IRS were to get more aggressive in seeking workpapers from
all taxpayers, the incentive to avoid tax shelter transactions
would disappear. (See Thomas F. Carlucci, et al, “The Perfect
Storm Gathers,” The Tax Executive, November–December
2005.)
Despite the restraint of current IRS policy and the reassurances
by Korb, there is still cause for concern. First, the acceleration
of workpaper requests in recent years suggests that the IRS may
be pushing its policy as far as possible. Second, current IRS
policy and Korb’s comments were made prior to the release
of FIN 48. Since then, IRS officials have been sending mixed signals,
sometimes indicating the IRS will stay the course with its policy
of restraint and at other times indicating that its workpaper
policy may be under review. With the new analysis and detail required
by FIN 48, the IRS will clearly be tempted to be more aggressive
in making workpaper requests.
Third, the IRS is clearly willing to take taxpayers to court
in support of its workpaper requests, at least in the tax shelter
arena. United States v. Textron, Inc. is currently pending
in the U.S. District Court for Rhode Island. In this case, the
IRS has accused Textron of engaging in several listed transactions
and is therefore seeking all of Textron’s tax accrual workpapers.
The outcome of this case may help define the parameters of the
IRS’s power in this area, clarify whether any sort of work
product privilege can apply in the tax accrual area, and shed
further light on the how the IRS is implementing its workpaper
policy. (For more on Textron, see Christopher M. Netram,
“Summons Enforcement Action Filed for Tax Accrual Workpapers,”
Tax Notes Today, May 2, 2006.)
To minimize the risk of IRS access, experts traditionally advised
corporate tax departments to provide independent auditors only
with summary information about their tax exposures (e.g., Thomas
F. Carlucci, et al, “The Perfect Storm Gathers,” The
Tax Executive, November–December 2005). The hope was
that if the auditor was not provided significant detail, then
confidentiality could be maintained, Arthur Young would
not apply, and the work-product and attorney-client privileges
would therefore be more likely to apply. Auditors’ reduced
documentation practices in the 1990s, previously discussed, aided
in this strategy. This approach is no longer feasible under FIN
48.
The AICPA professional audit standards instruct financial statement
auditors to consider lack of documentation access or existence
when forming an opinion on the financial statements. In general,
client-imposed limitations on access to material information will
result in significant report modifications, including the potential
for a disclaimer of opinion (AU 508.24). These standards apply
to all audits (both public and private) because AU 508 was adopted
by the PCAOB as part if its interim standards. As noted above,
auditors have more exposure in light of FIN 48 and will likely
not settle for mere summary schedules in support of the client’s
FIN 48 assertions.
More Disclosure, More Risks
The recent PCAOB and ASB documentation standards and FIN 48 should
result in more accurate financial reporting, more useful information
to auditors and investors, and better management of tax risks.
At the same time, these new rules create compliance headaches
for already overburdened corporate tax departments. Tax departments
should consider using the experience of their internal audit departments
to deal with this issue. The internal audit function is uniquely
situated to provide assistance in this area because it involves
internal control, tax, documentation, and audit standard expertise.
A more troubling problem, and one less easy to address, is that
the new rules result in tax accrual workpapers that can provide
the IRS with precise directions to the company’s tax exposures.
While the IRS has historically restrained itself, it has been
more aggressive recently in requesting tax accrual workpapers.
With so much detail now required, the IRS may be tempted to be
even more expansive in its scope.
Corporate tax departments are in a bind. They must provide
their auditors with the tax exposure information required by FIN
48 in order to ensure an unqualified opinion. Withholding information
from the auditors to keep it safe from IRS scrutiny is clearly
not an option. Corporate tax departments need to keep this risk
on their crowded radar screens, monitor IRS activity and the Textron
case, and collectively urge the IRS to maintain its historic restraint.
