EXPLANATION OF THE PROBLEM
e IRS leads taxpayers to expect that it will process their amended returns within 16 weeks. While this is
true for most amended returns, a subset takes longer to process or hits snags that the IRS does not explain
very well. e IRS does not disclose to taxpayers that if their amended returns are selected for audit,
processing will likely take several more months and sometimes the IRS will simply stop processing them. In
these situations, the Wheres My Amended Return tool, which is not available to business taxpayers, is of
little help because it has only three statuses (received, adjusted, or completed) and does not explain where an
amended return is in the processing pipeline or estimate when processing will be complete.
In fiscal year (FY) 2019, the IRS’s failure to set clear expectations and keep taxpayers informed of the status
of their amended returns generated over 2.2 million calls, 1.4 million of which it was able to answer, and
resulted in over 9,400 TAS cases.
2
Many taxpayers file an amended return to request a refund of a tax
overpayment, but the IRS also has the statutory authority to consider a taxpayers request to reduce an assessed
tax that remains unpaid, i.e., a request for abatement.
3
e IRS has exercised that authority and established
procedures for processing amended returns requesting an abatement.
4
However, it sometimes refuses to
consider the claim and issues a form letter without an adequate explanation to the taxpayer. e form letter

simply states the law does not allow a claim to reduce tax owed and instructs the taxpayer to pay the tax
followed by another amended return.
ANALYSIS
An amended return is not defined in the IRC, and taxpayers are not required to file an amended return.
5
e
Supreme Court has held an amended return is a creature of administrative origin and grace.
6
In practice,
taxpayers regularly file amended returns to correct an error on a previously filed return, and the IRS has
adopted specific procedures for handling amended returns.
7
Most individual taxpayers receive a refund after
they file an amended return. e IRS’s announced timeframe for processing individuals’ amended returns is
16 weeks.
8
e IRS advises that it often takes three to four months to process corporations’ amended returns.
9
Taxpayers who file amended income tax returns include:
Individuals filing Form 1040X, Amended U.S. Individual Income Tax Return;
10
Corporations filing Form 1120X, Amended U.S. Corporation Income Tax Return, or other Form
1120-series amended returns such as Form 1120-S, U.S. Income Tax Return for an S Corporation, and
checking a box on the form to indicate that the return is an amended return;
Partnerships filing Form 1065X, Amended Return or Administrative Adjustment Request (AAR), or
Form 1065, U.S. Return of Partnership Income, and checking a box on the form to indicate that the
return is an amended return; and
Estates and trusts filing Form 1041, U.S. Income Tax Return for Estates and Trusts, and checking a box
on the form to indicate that the return is an amended return.
In distinguishing between a request for abatement (i.e., a request for a “decrease in the tax that was assessed”)
and a request for refund (i.e., “a request for the return of a paid assessment”), the IRS notes that “[a]lthough
IRC Section 6404(b) provides that taxpayers have no right to file a claim for abatement of income, estate, or
gift tax, the Service will consider a taxpayer’s request for an abatement of such taxes where the taxpayer files an
amended return with the IRS that shows a decrease in the tax that was assessed.
11
Various codes on IRS computer systems show the receipt of an amended return and its movement through
different IRS functions as it is processed.
12
e codes do not show the correction the taxpayer sought on the

amended return, but they do show what adjustment was made to a taxpayers account after an amended return
was filed. e outcomes can be grouped into the following four categories:
Category 1: e IRS agreed the taxpayer made an overpayment of tax and issued a refund to the taxpayer
(or offset the overpayment to the taxpayers tax liability for a different year);
Category 2: e IRS abated some or all the tax, i.e., the IRS adjusted its records to show the taxpayer
owed less tax than the amount shown on the original return;
Category 3: e IRS adjusted its records to show the taxpayer owed more tax than the amount shown on
the original return; or
Category 4: e IRS did not make any change to its records to reflect information shown on the
amended return. is category includes cases in which the IRS rejected or declined to consider the
change proposed on the amended return, and where the IRS disallowed refunds requested on an
amended return.
Figure 1.9.1 shows an estimate of the number of amended returns the IRS processed in FYs 2017-2019 by the
type of filer and the ensuing adjustment to the taxpayers account, according to the categories described above.

As the “Total” column in Figure 1.9.1 shows, individual taxpayers file the most amended returns; corporations
file the next largest number of amended returns.
14
In terms of outcome, most individual taxpayers belong
to Category 1 (i.e., the taxpayer was issued a refund, or the overpayment was offset to a different years tax
liability). Most business taxpayers belong to Category 4 (i.e., no change). e Category 4 “no change
outcome is the second most likely outcome for individual taxpayers. us, this discussion focuses on the two
largest groups of taxpayers — individuals and corporations — and Categories 1 and 4 outcomes.
15
Estimated median processing time of amended returns varied depending on whether the IRS examined, or
audited, the amended return, as discussed below.
Examinations Add Months to Median Processing Time
As Figure 1.9.2 shows, the estimated overall median processing time for individual amended returns
that resulted in a refund was never more than four weeks overall when the return was not audited.
(Estimated median processing time for these amended returns doubled from two weeks to four weeks from
FYs 2017-2019 but was well within the announced 16-week timeframe.) In FY 2017, estimated median
processing time for these audited returns stretched up to 35 weeks; by FY 2019, it had decreased to 20 weeks,
a significant improvement compared to FY 2017, but still 25 percent longer than taxpayers were told to
expect.

Most Serious Problem #9: Amended Returns
Taxpayer Advocate Service136
Most Serious Problems
For many individual taxpayers and most business taxpayers, amended returns result in no change to their
tax liability. Figure 1.9.3 shows the estimated median processing times for these amended returns filed
by individuals and by corporations according to whether the return was audited. While individuals
unaudited returns in this category were processed in two to four weeks, estimated median processing time for
corporationsunaudited amended returns increased from eight to 17 weeks in FYs 2017-2019.
For audited individual and corporate amended returns that resulted in no change, estimated median
processing time in FY 2017 was 32 weeks for individuals and 47 weeks for corporations. By FY 2019, these
estimated median processing times were 29 weeks for individuals and 37 weeks for corporations.

Whether a taxpayer files an amended return on paper or electronically, the IRS processes it manually.

In
terms of outcomes, most taxpayers belong to Category 1 or Category 4 (i.e., the taxpayer either received a
refund or no change resulted from the amended return). e processing steps generally followed by audited
amended returns filed by individuals and corporations with estimated processing timeframes for Category 1
and Category 4 cases in FYs 2017-2019 are summarized in Figure 1.9.4.

1. Amended Returns Routed to Accounts Management
The IRS Submission Processing (SP) function receives individual taxpayers’ amended returns. SP either (1) evaluates the
requested adjustment and makes (or declines to make) the requested changes or (2) routes the amended return to the
AM function, a process that took an estimated two to four weeks.
1
Corporations’ amended returns are routed directly to AM
for processing (SP records the receipt of amended returns but does not process them further).
2
2. Amended Returns Selected for Audit
AM evaluates some amended returns but is required to refer some amended returns, known as
CAT-A returns, to the Examination function (Exam).
3
Exam then selects some of these amended
returns for examination. This process, which applied to about three percent of the individual
amended returns and about 1.3 percent of corporations’ amended returns AM received in Step 1,
took an estimated median of five to six weeks for individual amended returns and less than a
week for corporate amended returns.
3. Amended Return Assigned to Auditor and Audit Opened
Some amended returns selected for audit are assigned to an examiner (who contacts the
taxpayer), and an audit is opened. This step, which applied to between 27 percent and 56 percent
of individual amended returns and between 8.5 and 44 percent for corporations’ amended returns
selected for audit in Step 2, took an estimated median of three to nine weeks for individual amended
returns, and 14 to 16 weeks for corporate amended returns.
4. Amended Return Audit Closed
The examiner concludes the audit and closes the case, which took an
estimated median of 17 to 20 weeks for individual amended returns, and
35 to 41 weeks for corporate amended returns.
4
Thus, the median exam
time alone took just as long or longer than all the preceding steps 1-3.
1 The applicable IRM during FYs 2017-2019 provided for a timeframe of 12 calendar days (20 days during the March-June peak filing
season) to route amended returns from SP to AM. See, e.g., IRM 3.11.6.2(8), General Form 1040-X Information (Nov. 21, 2019). The
decision to route the individual’s amended return to AM is “based on the issue, the dollar tolerance, computer program capabilities
(e.g., Blocking Series), and other various reasons.” IRM 3.11.6.4.15 (1), Accounts Management Cases (Jan. 2, 2019). This processing
step is automated for electronically filed Forms 1040X, which is expected to reduce delays. IRS response to fact check
(Nov. 24, 2020). Due to the COVID-19 pandemic, as of September 26, 2020, there were over a million Forms 1040X in SP inventory,
of which about 974,000 were more than 21 days old. IRS, JOC, Customer Account Services Form 1040X Consolidated Inventory
Report, Submission Processing (Sept. 26, 2020).
2
IRM 21.7.4.4.4.11.13, Form 1120-X, Amended U.S. Corporation Income Tax Return (Oct. 1, 2020). As of Sept. 26, 2020, there were more
than 230,000 Forms 1120X in AM inventory, of which about 89,000 were more than 120 days old. IRS, JOC, AMIR National Inventory
Age Report (Sept. 26, 2020). The 120 days begins on the date the IRS received the amended return, as recorded by SP; thus, the
delays in SP processing described above overflowed into AM.
3 IRM 21.5.3-2, Examination Criteria (CAT-A) – General (Aug. 7, 2020). CAT-A criteria were established based on past examinations that
identified characteristics indicating a high degree of noncompliance.
4 The maximum time it took to close a case in FYs 2017-2019 was 99 weeks for an individual amended return case and 101 weeks for a
corporate amended return case, i.e., once opened, these audits alone took almost two years to conclude.

DELAYED REFUNDS CAUSE THE GOVERNMENT TO INCUR INTEREST CHARGES
e government is required to pay interest on the overpayments taxpayers claim, and the interest generally
begins to accrue 45 days after the taxpayer requests a refund from the IRS.
23
us, delays in processing
amended returns on which taxpayers seek refunds contribute to overpayment interest.
24
Millions of Taxpayers Call the IRS Seeking Information About Their Amended Returns
Since 2013, the IRS has provided a “Wheres My Amended Return” tool.
25
e tool is accessible online at
IRS.gov or by calling a toll-free number for an automated phone system, referred to as the amended return
hotline. e tool allows taxpayers to ascertain whether the IRS received their amended return, whether the
IRS made any adjustment to their accounts, and whether processing of the amended return is complete.
However, beyond these three statuses (received, adjusted, or completed), the tool does not explain where an
amended return is in the processing pipeline or estimate when processing will be complete.
26
Moreover, the
application is not available for business taxpayers or for taxpayers who file an amended return with a foreign
address, among others.
27
In FY 2019, taxpayers accessed the tool online through IRS.gov more than five
million times and called the amended return hotline more than 2.2 million times; 1.4 million of these calls
were answered.
28
Taxpayers Seek Assistance From TAS in Resolving Amended Return Issues
In each of FYs 2017-2019, the fourth most common reason taxpayers came to TAS was for assistance in
resolving problems caused by amended return processing.
29
Past analysis of TAS cases with this issue showed
that the underlying factor in these cases is that the processing period greatly exceeded the IRS’s announced

timeframe.

As discussed above, processing time is considerably lengthened when taxpayers’ amended returns
are audited. A review of TAS cases that were closed in FY 2019, discussed below, suggests that taxpayers
encounter an additional difficulty: the IRS may refuse to consider their amended returns on which they
request an abatement of tax.
In Letter 916C, the IRS Declines to Consider Amended Returns Requesting Abatement
of Tax
e IRS has the statutory authority to abate income taxes; it has exercised that authority and has adopted
procedures for processing amended returns that request abatement.
31
As Figure 1.9.1 shows, the IRS abated
taxes in about 100,000 cases each year in FYs 2017-2019 (Category 2 cases). Yet, in some situations the IRS
refuses to consider these claims.
For some amended returns requesting an abatement of tax the IRS sends the taxpayer Letter 916C, Claim
Incomplete for Processing; No Consideration.
32
Letter 916C is a blank template, with the IRS employee
developing the content of the letter by selecting among pre-written paragraphs including Paragraph M.
33
Paragraph M of Letter 916C says:
e law allows you to file a claim for a refund of taxes you have paid. However, the law doesnt
allow you to file a claim to reduce the tax you owe. If you disagree with the amount of tax you
owe, you can appeal our decision. To appeal our decision, you must:
Pay the tax you owe.
File an amended return with documentation that supports a reduction in the tax you owe.
File your claim for refund within 3 years from the date you filed your return or 2 years from the
date you paid your tax, whichever is later.
34
e reference to the option to “appeal our decision” in paragraph M does not refer to the right to an
administrative appeal, which is not available in tax abatement cases, but rather to the right to pay the assessed
tax, request a refund from the IRS (which may include an administrative appeal), and if unsuccessful, bring a
refund suit in a U.S. district court or the U.S. Court of Federal Claims.
35
While taxpayers are required to pay
the assessed tax before they may bring a refund suit in federal court, there is no requirement that they pay an
assessed tax before they seek abatement of some or all of the tax from the IRS.

Most Serious Problems
e IRS justifies including Paragraph M in Letter 916C when requests for abatement do not contain adequate
explanation or documentation by affirming that:
is procedure was established to provide a courtesy to the taxpayers, to allow AM CSR’s
[Customer Service Representatives] to consider a claim, even though the taxpayer may not
have paid the tax they owe. Instead of outright denying the claim, AM CSR’s will review the
claim in full and determine if it is fully processable and contains all the necessary supporting
documentation.
37
e IRS also notes: “[t]hat is why in IRM 21.5.3.4.6(3), we advise our CSR’s not to deny claims based solely
on the nonpayment of tax, rather to consider the claims if they contain all of the necessary documentation.
It appears the IRS considers requests for tax abatement, but only if the request is submitted with adequate
explanation and documentation. When the request is incomplete, rather than asking taxpayers to provide the
missing information, taxpayers are told that “the law doesnt allow you to file a claim to reduce the tax you
owe.”
38
is practice is unacceptable. e IRS should contact the taxpayer and provide a reasonable period of
time to submit documentation in support of the request for abatement.
Each Year, TAS’s Inventory Includes Abatement Requests the IRS Did Not Consider
In FY 2019, TAS closed 9,602 cases in which the primary issue was IRS delays in processing amended
returns.
39
Of these, there were 240 “no consideration” cases in which the taxpayer, after filing an amended
income tax return, was issued Letter 916C that was viewable on IRS databases.
40
Even though these cases
comprise a small portion (three percent) of TAS cases involving delays in processing amended returns, they
demonstrate inconsistencies in the IRS’s treatment of amended returns.
Of the 240 cases, in 52 cases the taxpayer sought an abatement of tax rather than a refund. In 22 of these
52 cases (42 percent), Letter 916C informed the taxpayer that the law does not allow claims for abatements.
Either Paragraph M was selected (18 cases) or a fill-in paragraph contained the same information (four
cases).
41
In all 22 cases except one, this was the only reason given for not considering the claim (i.e., in only
one case was the taxpayer advised that the supporting information was not complete).
CONCLUSION AND RECOMMENDATIONS
Most amended returns filed by individuals result in a refund, and the IRS usually processes these amended
returns within its announced timeframe of 16 weeks, although auditing these returns increased processing
time to a median of 20 weeks in FY 2019. Amended returns filed by individuals and corporations often do

not result in any change in liability. When they are not audited, these amended returns are usually processed
timely (within a median time of four weeks for individuals and 17 weeks for corporations in FY 2019). When
these amended returns are audited, processing times increase significantly, reaching an estimated median
of 29 weeks for individuals and 37 weeks for corporations in FY 2019; these taxpayers wait seven or eight
months to learn, e.g., that their claimed refund or request for tax abatement was denied. e main driver of
increased processing times for audited amended returns is the time it takes to conduct the audit.
e IRS has the authority to abate income taxes. It has exercised that authority and adopted procedures for
considering requests for tax abatement submitted on an amended return. About 100,000 amended returns
result in tax abatement each year. However, a review of TAS cases shows that when the IRS refuses to consider
requests for tax abatement, it frequently cites as the reason for its refusal that the law doesnt allow taxpayers
to file a claim to reduce the tax they owe. at response is misleading and undermines taxpayers rights to be
informed and to pay no more than the correct amount of tax.
Preliminary Administrative Recommendations to the IRS
e National Taxpayer Advocate preliminarily recommends that the IRS:
1. Change its procedures by:
a. Revising the IRM to provide that if a request for tax abatement is incomplete, the employee
should solicit the necessary documentation from the taxpayer, and if the documentation is not
forthcoming or is insufficient, the employee should deny the request, explain the reason for the
denial, and explain the different procedures that apply to requests for tax abatement and requests
for refund;
b. If the IRS determines the taxpayer is not entitled to an abatement, issuing a 30-day letter
providing taxpayers the right to file a protest with the Independent Office of Appeals
42
for
abatement of tax and updating and clarifying the IRM’s No Immediate Tax Consequence
provisions by referencing abatement cases;
c. Removing any selectable paragraph in Letter 916C that states the law does not allow taxpayers
to file a claim to reduce the tax they owe or appears to advise taxpayers that they cannot seek an
abatement of tax without first paying the amount of tax already assessed (Paragraph N in the
current version of Letter 916C); and
d. Revising the IRM to instruct employees not to use a fill-in paragraph in Letter 916C to state the
law does not allow taxpayers to file a claim to reduce the tax they owe or to inform taxpayers they
cannot seek an abatement of tax without first paying the amount of tax already assessed.
2. Identify and address the cause of lengthy examination times for amended returns.
3. Identify and address the cause of the increase in processing time for corporations’ unaudited amended
returns.
4. Add additional status updates to the “Wheres My Amended Return” tool to allow taxpayers to see
when the IRS selects their amended return for audit, when it assigns the audit to an examiner, and
what an estimated completed processing time is based on the returns current status.

IRS COMMENTS
e IRS is committed to processing amended returns accurately and efficiently. On August 17, 2020,
the IRS began receiving electronic Forms 1040X, Amended U.S. Individual Income Tax Return,
which has been an important goal for the IRS and our industry partners for many years. Electronically
filing a Form 1040X will reduce errors and decrease processing time. As of November 21, 2020, over
144,000 electronically filed amended returns have been accepted from 18 industry partners. Future
upgrades will allow taxpayers to file an electronic amended return for the current and two prior years.
And, although the IRS has been converting more complex paper amended returns into electronic
Correspondence Imaging System (CIS) cases for years, we initiated a pilot process in October 2020 to
convert less complex paper amended returns to CIS cases. If the pilot is successful streamlining our
ability to work and resolve these cases, we plan to implement the process Servicewide.
We are making progress in reducing the Business Masterfile (BMF) amended return inventory that
has increased due to the lapse in appropriations in 2019 and office closures due to COVID-19 in
2020. As of November 2020, the current BMF inventory is about 670,000 cases, down 20 percent
from a peak of 840,000 cases one year prior. We anticipate BMF amended return processing will
increase once new employees are trained and are focused on this inventory.
Our efforts to ensure compliance with the tax laws extend to amended returns. Before determining
whether to survey or examine an assigned claim for refund, examiners thoroughly review the return to
identify large, unusual, or questionable items per IRM 4.10.2.3, In-Depth Pre-Contact Analysis, and
evaluate the audit potential of the entire return, and possibly, for related returns for the same or other
tax years. e examination is not limited to the issues raised in the claim for refund if there are other
issues that warrant further consideration (IRM 4.10.11.2.4 and 4.10.11.3.3). erefore, the effort
and time required to examine an amended return can rise to the same level as in other examinations,
although current data shows the cycle time for examinations on amended returns is lower than other
examinations both in Field and Campus operations (269 days in fiscal year 2020 compared to 319
days for all examinations). e length of any audit is based on the unique facts and circumstances
of each case, the timeliness of taxpayer responses to IRS letters, and may be affected by the need
to balance competing priorities or extenuating circumstances such as disasters. To help expedite
examinations, campuses began forwarding claims and assigning cases to the field electronically in
July 2020.
We are always seeking to improve how we communicate with taxpayers and will consider how the
“Where’s My Amended Return” tool could be improved in this regard, taking into account cost and
competing IT priorities. We will also review and consider other recommendations provided by the
National Taxpayer Advocate.
Some amended returns include requests for abatement of tax owed, before the tax is paid. Currently,
we consider these requests where sufficient documentation is provided. We do so as a courtesy to
taxpayers, to allow the Service to consider a claim even though the taxpayer has not paid the assessed

tax that is due. We are working with the IRS Office of Chief Counsel to determine how best to
address the concerns raised by the Advocate with our procedures in addressing requests for abatement
that are incomplete.
TAXPAYER ADVOCATE SERVICE COMMENTS
TAS understands that there are good reasons why amended returns may take almost as much time to
audit as other returns. TAS looks forward to the improved processing times expected to result from
electronic filing, electronic assignment of some cases that are assigned for exam, and scanning some
paper returns so they are accessible in the CIS database. In any event, taxpayers should be given
more realistic estimates of what the expected processing time will be; the IRM should be adjusted if
the current 16 week expected processing time is no longer accurate, and the Wheres My Amended
Return tool should be improved accordingly. e Form 1120X instructions should likewise be
adjusted if the referenced processing time of three to four weeks is not accurate.
However, the IRS’s explanation for lengthy processing times for amended returns filed by businesses
is not supported by the data in this report, which is based on operations for FYs 2017-2019. ere
was indeed a government shutdown due to a lapse of appropriations in FY 2019, as the IRS notes,
but amended return processing times improved in FY 2019 compared to FYs 2017 and 2018. e
COVID-19 pandemic affected IRS operations, but not until FY 2020.
e National Taxpayer Advocate appreciates the IRS’s willingness to work with the IRS Office of
Chief Counsel to better address requests for abatement. As with any other taxpayer request, the IRS
should advise taxpayers when they need to submit additional information in order for their request
to be considered. e blanket statement currently in use (that the law doesnt allow taxpayers to file
a claim to reduce the tax owed) without further explanation is not appropriate and often confusing
for taxpayers. Providing the taxpayer an administrative review or initiating a specific request for
documentation prior to rejection should be standard procedures. e IRS should also consider
permitting these taxpayers to appeal their cases to the Independent Office of Appeals rather than
having to pay the tax the taxpayer believes is not due, then file another claim of refund, or bring a
refund suit in order for the IRS to review their documentation. Taxpayers have the right to pay no
more than the correct amount of tax, and the IRS should assist them with that determination.

RECOMMENDATIONS
Administrative Recommendations to the IRS
e National Taxpayer Advocate recommends that the IRS:
1. Revise the IRM to provide that if a request for tax abatement is incomplete, the employee
should solicit the necessary documentation from the taxpayer, and if the documentation is not
forthcoming or is insufficient, the employee should deny the request, explain the reason for
the denial, and explain the different procedures that apply to requests for tax abatement and
requests for refund.
2. If the IRS determines the taxpayer is not entitled to an abatement, issue a 30-day letter
providing taxpayers the right to file a protest with the Independent Office of Appeals
43
for
abatement of tax and updating and clarifying the IRM’s No Immediate Tax Consequence
provisions by referencing abatement cases.
3. Remove any selectable paragraph in Letter 916C that states the law does not allow taxpayers
to file a claim to reduce the tax they owe or appears to advise taxpayers that they cannot seek
an abatement of tax without first paying the amount of tax already assessed (Paragraph N in
the current version of Letter 916C).
4. Revise the IRM to instruct employees not to use a fill-in paragraph in Letter 916C to state the
law does not allow taxpayers to file a claim to reduce the tax they owe or to inform taxpayers
they cannot seek an abatement of tax without first paying the amount of tax already assessed.
5. Identify and address the cause of lengthy examination times for amended returns.
6. Identify and address the cause of the increase in processing time for corporations’ unaudited
amended returns.
7. Add additional status updates to the “Wheres My Amended Return” tool to allow taxpayers
to see when the IRS selects their amended return for audit, when it assigns the audit to an
examiner, and what an estimated completed processing time is based on the returns current
status.
8. Revise the IRM and Form 1120X instructions to more accurately reflect the expected
processing time for amended returns.

Appendix A
METHODOLOGY
Traditional amended return data found on IRS databases includes items such as IRS received dates,
transaction codes, action codes, and transaction dates. For example, we identified individual amended returns
by searching taxpayer accounts for a transaction code of 971 and an action code of 120. e data in this
report was gathered according to the following methodology:
1. Only one amended return per taxpayer per fiscal year was taken into account. If a taxpayer filed more
than one amended return in the same fiscal year, whether or not it was with respect to the same tax
year, only the earliest amended return was included, and processing times were computed with respect
to that amended return. If a taxpayer filed more than one amended return with respect to the same
tax year, the amended returns were all included in the analysis to the extent they were filed in different
fiscal years.
2. Also not included in the analysis are individual amended returns that were filed after an audit was
opened and amended returns that were filed with a function other than Submission Processing (e.g.,
IRS Appeals, IRS Exam, Automated Underreporter Unit).
3. e analysis of individual amended returns is limited to individual amended returns filed on Form
1040X, although the IRS also processes as amended returns some filings taxpayers submit on another
IRS form, such as Form 1040, U.S. Individual Income Tax Return, that indicate the filing is intended
to be an amended return.
4. Other Business Master File returns not included in Figure 1.9.1 include, e.g., employment tax, estate
tax, gift tax, excise tax, and tax-exempt organization returns.
Processing Times of Audited Amended Returns in Categories 1 or 4
Step 1: SP routes amended returns to AM: In FYs 2017-2019, SP received 2,152,508; 2,383,472; and
1,998,609 Category 1 and 4 Forms 1040X, respectively. SP routed 909,464 (42 percent); 929,902 (39
percent); and 791,716 (40 percent) of these returns to AM in FYs 2017-2019, respectively.
44
is step took
an estimated median of two weeks, three weeks, and four weeks in FYs 2017-2019, respectively. In addition,
SP routed 183,817; 184,605; and 194,508 Forms 1120X in Categories 1 and 4 to AM in FYs 2017-2019,
respectively.
Step 2: AM refers CAT-A returns to Exam, and Exam selects some of them for audit: is process, which
affected a small portion of amended returns, took an estimated median of five to six weeks for individual
amended returns, and less than a week for corporate amended returns, as shown in Figure 1.9.A1.
