HIGHLIGHTS: Management Took Actions to Address Erroneous Employee
Retention Credit Claims; However, Some Questionable Claims Still Need to Be Addressed
Final Audit Report issued on September 30, 2024
Report Number 2024-400-068

Why TIGTA Did This Audit
In July 2021 and August 2022,
TIGTA issued reports on the IRS’s
efforts to implement employer tax
credits included in the Coronavirus
Disease 2019 Pandemic (Pandemic)
relief legislation. This report is a
continuation of our review of the
Employee Retention Credit (ERC).
The overall objective of this review
was to assess the IRS’s processes
to ensure the accuracy of both
original and amended returns with
the ERC, and the IRS’s compliance
initiatives to prevent or recover
erroneous ERC.
Impact on Tax Administration
The ERC was intended to provide
businesses with relief from the
adverse financial effects of the
Pandemic. Delays in processing
ERC claims may impact legitimate
businesses that are eligible for the
ERC and could result in increased
interest paid by the IRS to these
businesses, if a determination is
made that the ERC claim is
legitimate.
The IRS must balance taxpayer
burden and potential interest it
may be required to pay with
ensuring adequate scrutiny of ERC
claims. The unintended
consequences of refundable
credits are that they can result in
the issuance of improper payments
and can be the targets of
unscrupulous individuals. As such,
they pose a significant risk as an
avenue for those seeking to
defraud the Government.
On September 14, 2023, the IRS
placed a moratorium on
processing new ERC claims due to
a surge in the volume of suspicious
claims from unscrupulous actors.

What TIGTA Found
IRS management increased awareness about ERC eligibility
requirements. For example, the IRS issued numerous press releases
and electronic news articles to tax professionals and other
subscribers about both eligibility requirements and ERC promoters.
These news articles also directed taxpayers to frequently asked
questions and other eligibility information on the IRS’s website, such
as a new eligibility checklist. The IRS also updated identity theft
filters and reports it identified more than 155,000 tax returns claiming
potentially erroneous ERC preventing $487 million in refunds from
being issued during Processing Years 2021 through 2023. However,
the IRS does not apply updated filters to tax returns that were
previously screened using old criteria. TIGTA identified 997 returns
reporting $19.6 million in potentially erroneous ERC through
July 20, 2023, that the IRS did not identify.
Our review also found that through June 29, 2023, IRS management
made decisions to double the threshold and change the referral
criteria to include only returns that met specific return scenarios. The
threshold and scenarios were used to determine which returns
should be referred for possible prerefund examination and which
returns should have the ERC claim paid. According to IRS
management, these changes were to deal with the influx of ERC
claims and to expedite the processing of ERC claims. However, these
decisions led to 184,923 returns claiming $41.8 billion in the ERC
from being considered for possible prerefund examination.
Finally, IRS management implemented several initiatives after the
moratorium that assessed or prevented erroneous ERC amounts.
These initiatives have prevented $1.6 billion in the ERC and allowed
the IRS to assess $573 million in the ERC as of April 13, 2024.
However, TIGTA identified an additional 923 entities that claimed the
ERC of $105 million that should have received a disallowance letter
but were not initially identified by the IRS.
What TIGTA Recommended
TIGTA made four recommendations, including that IRS management
review the 997 tax returns not flagged by identity theft filters and the
184,923 tax returns not considered by the IRS for possible prerefund
examination, and consider these returns for post-refund compliance
review to recover any potentially erroneous ERC paid. In addition,
TIGTA recommended that the IRS send disallowance letters to the
923 entities that did not initially receive a letter.
The IRS agreed with three recommendations and plans to review and
refer additional tax returns that met its updated identity theft filters
for recapture where appropriate, issue disallowance letters to the
923 entities TIGTA identified, and update its strategy to identify
businesses for ERC recapture in subsequent years. The IRS partially
agreed to review the 184,923 tax returns citing the need to assess
competing priorities, resources, and remaining time on statutes.

Credit Claims; However, Some Questionable Claims Still Need to Be Addressed
Background
The Employee Retention Credit (ERC) is a refundable employer tax credit introduced in the
Coronavirus Aid, Relief, and Economic Security Act (CARES Act).1 The credit encouraged eligible
employers to keep employees on their payroll despite experiencing economic hardship related
to the Coronavirus Disease 2019 Pandemic (Pandemic). Employers could claim the ERC on
Form 941, Employer’s QUARTERLY Federal Tax Return.2 Eligible employers that did not claim the
ERC on their original Form 941 or that wanted to adjust the amount originally claimed could file
a Form 941-X, Adjusted Employer’s QUARTERLY Federal Tax Return or Claim for Refund
(Forms 941-X claims are hereafter referred to as ERC claims).3
The legislation relating to the ERC was amended three separate times between March 2020 and
November 2021.4 The amendments changed both the amount of the credit and eligibility
requirements. For example, the credit increased from $5,000 per employee per tax year to
$7,000 per employee per quarter. The amendments also occurred at a time when the Internal
Revenue Service (IRS) was not only dealing with the Pandemic, but also working to implement
processes to effectively process legitimate claims while providing adequate scrutiny. The timing
of the various legislative changes increased the number of ERC claims received by the IRS.
Figure 1 provides a summary of ERC legislative changes.

1 The ERC can be a nonrefundable credit, a refundable credit, or both, depending on the amount of the credit that can
be claimed for a particular tax period and the amount(s) of certain other nonrefundable credit(s) being reported. How
the credit is applied depends on the tax period for which it is being claimed. Pub. L. No. 116-136, 134 Stat. 281
(codified as amended in scattered sections of 2, 5, 12, 15, 20, 21, 29, 42, and 45 U.S.C.), as amended by the
COVID-Related Tax Relief Act of 2020 and the Taxpayer Certainty and Disaster Tax Relief Act of 2020 (2020). See
Appendix IV for a glossary of terms.
2 Employers could also claim the ERC on Form 943, Employer’s Annual Federal Tax Return for Agricultural Employees;
Form 944, Employer’s ANNUAL Federal Tax Return; and Form CT-1, Employer’s Annual Railroad Retirement Tax
Return.
3 Employers could also file an ERC claim on Form 943-X, Adjusted Employer’s Annual Federal Tax Return for
Agricultural Employees or Claim for Refund; Form 944-X, Adjusted Employer’s ANNUAL Federal Tax Return or Claim
for Refund; and Form CT-1 X, Adjusted Employer’s Annual Railroad Retirement Tax Return or Claim for Refund.

The IRS experienced delays in processing ERC claims
The IRS also experienced the effects of the Pandemic. For example, we previously reported that
the Tax Processing Centers were closed between March 20, 2020, and June 29, 2020, which
resulted in significant backlogs of unopened mail.6 In August 2022, we reported that continued
processing delays prevented businesses from receiving Pandemic relief benefits.7 Specifically,
the IRS did not begin processing ERC claims for 12 months, due to a lack of updated
programming and procedural guidance.
Figure 2 shows the timeline of processing ERC claims through February 9, 2022.
Figure 2: Processing Timeline for ERC Claims

Source: TIGTA summary of Servicewide Electronic Research Program Alerts.
The IRS began processing ERC claims for the first time between March and April 2021. However,
because these ERC claims were filed on paper forms, they were processed manually, not
electronically. Thus, working through the backlog of ERC claims was challenging for the IRS and
frustrating for employers and stakeholders.
Eligibility is difficult to determine without adequate data
Refundable tax credits, such as the ERC, present a unique risk to tax administration because
taxpayers not only can have their tax reduced to zero; they can also receive a "refund" of excess
credit. The unintended consequences of refundable credits are that they can result in the
issuance of improper payments and can be the targets of unscrupulous individuals. As such,
they pose a significant risk as an avenue for those seeking to defraud the Government.
Specifically for the ERC, the IRS does not have all the data it needs to verify the eligibility of the
employer to claim the credit or accuracy of the claims by employers for the ERC. For example,
the IRS had no data to support whether the employer fully or partially suspended operations
due to a Pandemic government order, whether it experienced a decline in gross receipts, or how

much it paid its employees during the relevant time period. In an instance like this, the only way
the IRS could determine if an employer met these eligibility criteria would be through a
resource-intensive examination, which would require the employer to cooperate and provide the
necessary documentation for the IRS’s review.
The IRS increased its focus on ineligible ERC
In March 2023, the IRS updated its annual “Dirty Dozen” list to include companies that promote
large refunds related to the ERC, i.e., making offers that are too good to be true. According to a
news release, the IRS “spotlighted ERC following blatant attempts by promoters to con ineligible
people to claim the credit.” In this same news release, the IRS announced that it would be
stepping up enforcement action involving these ERC claims and that “people considering filing
for these claims – only valid during the pandemic, for a limited group of businesses – should be
aware they are ultimately responsible for the accuracy of the information on their tax return.”
The IRS added resources to assist with processing the inventory of ERC claims, as the IRS
previously received ERC claims at a faster pace than it could process them. In addition, the IRS
received more claims than when the ERC was originally enacted into law. For example, total
amended business returns filed as of March 25, 2023, had already exceeded those filed during
Fiscal Year 2021. Furthermore, the IRS continued to receive pressure from external stakeholders
to accelerate processing tax returns claiming the ERC, because the ERC provided businesses with
much needed relief from the adverse financial effects of the Pandemic. As a result, the IRS
publicly committed to increase the number of employees working ERC cases to reduce the
inventory.
Figure 3 provides an overview of events that occurred during Calendar Year 2023 leading up to
the IRS’s moratorium on processing the ERC.

Credit Claims; However, Some Questionable Claims Still Need to Be Addressed
After the moratorium was announced, the IRS continued processing ERC claims it had already
received, but with additional scrutiny and at a much slower rate. New ERC claims received by
the IRS after the moratorium were held while the agency developed plans for handling growing
concerns with noncompliance. The IRS subsequently announced a series of initiatives intended
to either prevent ineligible ERC claims from being paid or to recover erroneous ERC claims
previously paid. This included:
•
Withdrawal initiative.8 The withdrawal option allowed certain employers, including those
that were pressured or misled by ERC promoters into filing ineligible requests for the
ERC, to withdraw their submission. Eligible employers were those that had not yet
received a refund, or that received a check but had not yet cashed or deposited it.
Claims that were withdrawn will be treated as if they were never filed. As such, the IRS
will not impose penalties or interest. As of April 17, 2024, the IRS was still accepting
requests for ERC withdrawals.
•
Voluntary Disclosure Program (VDP).9 This initiative incentivized businesses that received
the ERC in error to voluntarily repay 80 percent of the claim the business received. In
addition, the employer was not required to repay any interest it may have received on
the ERC refund, and the IRS would not charge penalties and interest on the claimed ERC
amount if the employer repaid the 80 percent in full. This initiative was in effect from
December 21, 2023, through March 22, 2024.
In addition, the IRS conducted data analysis and sent letters to employers in two high-risk
categories. This included employers that did not meet certain eligibility requirements for the
ERC and employers whose claims were erroneous or excessive, as detailed below:
•
Entity did not exist or did not pay employees during the period of ERC eligibility.10 As
shown in Figure 1, the ERC applied to qualified wages for periods from March 13, 2020,
through December 31, 2021. Entities that were established after December 31, 2021, or
did not have employees who were paid during an eligible period were not entitled to
claim the ERC. The IRS sent Letter 105 C, Claim Disallowed, to employers that did not
meet these basic eligibility requirements.
•
Recapture letters.11 The IRS identified employers for which the ERC paid exceeded the
maximum allowable amount based upon the number of Forms W-2, Wage and Tax
Statement, the amount of qualified wages, or the amount of compensation reported.
The IRS sent Letter 6577, ERC 2020 W-2, to these employers proposing tax adjustments
to their Tax Year 2020 tax return to recapture the erroneously claimed ERC.

Results of Review
This review is a continuation of our review of the IRS’s processing of claims for the ERC. We
previously issued reports in July 2021 and August 2022. The results in this report are presented
as of April 18, 2024.
The backlog and processing of ERC claims continued to be a challenge for the IRS during
Calendar Years 2022 and 2023. As of April 13, 2024, the IRS reported 1.4 million in ERC
inventory waiting to be worked. However, the IRS’s increased focus on ineligible requests for
the ERC prevented $1.6 billion and assessed $573 million in the ERC as of April 18, 2024.12
Management Increased Awareness About the Eligibility Requirements and
Prevented Erroneous Employee Retention Credit Amounts
With an increased number of ineligible ERC requests identified, the IRS took steps to increase
eligibility awareness and prevent potentially erroneous ERC. These steps included:
•
Conducting outreach and raising awareness about both eligibility requirements and ERC
promoters. The IRS issued numerous press releases and electronic news articles to tax
professionals and other subscribers on these topics. These news articles also directed
taxpayers to frequently asked questions and other eligibility information on the IRS’s
website.
•
Publishing a new eligibility checklist on IRS.gov with a tool to allow businesses to answer
step-by-step questions to determine their eligibility for the ERC. The IRS also provided a
printable checklist with all five eligibility questions and information about how to claim
the ERC or resolve an incorrect ERC claim previously filed. Our review of this checklist
found that it was accurate, complete, and streamlined for taxpayers.
•
Creating six business rules to identify potentially erroneous ERC claimed on original
returns at tax return filing. Business rules are used to validate information included on
electronically filed tax returns for acceptance into tax return processing. The IRS rejects
electronically filed tax returns from processing when the return does not meet a business
rule condition. Our review of the six business rules found that they were accurately
accepting and rejecting electronically filed returns claiming the ERC.
•
Implementing three identity theft filters to identify suspicious Forms 941 reporting the
ERC, all of which were updated for Processing Year (PY) 2023. During PYs 2021 through
2023, the IRS reports it identified more than 155,000 tax returns claiming potentially
erroneous ERC and prevented $487 million in refunds from being issued. The IRS
proactively updates the identity theft filters when it receives information relating to new
schemes. However, when the IRS modifies or updates its filter criteria, it does not apply
the updated filters to tax returns that were previously screened using the old criteria.
Using the IRS’s updated filter criteria as of July 20, 2023, we analyzed Forms 941 that
were processed during PYs 2021 through 2023, as of the same date. Our review

12 Using its recapture regulations, the IRS is reclaiming excessive or erroneous ERC through normal tax assessment and
collection procedures.

Page 7

Credit Claims; However, Some Questionable Claims Still Need to Be Addressed
identified 997 Forms 941 reporting $19.6 million ($19.1 million refundable and
$0.5 million nonrefundable) in potentially erroneous ERC claims. Because potentially
erroneous ERC was paid and given the IRS’s emphasis to more heavily scrutinize
potentially erroneous ERC, it is important that the IRS review these returns and recover
any erroneous amounts.
Recommendation 1 (E-Mail Alert): On February 28, 2024, we alerted the ERC Team Lead of
our concern and recommended that the IRS review the 997 tax returns we identified and
consider them for post-refund compliance review to recover potentially erroneous ERC paid.

Management’s Response to E-Mail Alert: IRS management agreed with the
recommendation. Taxpayer Services previously identified 525 of these modules for
potential recapture of an improperly paid credit. The IRS will analyze the remaining
472 modules and refer these to the Small Business/Self-Employed Division for recapture
where appropriate.
Management’s Decisions Led to Billions of Dollars in Claims Not Being
Considered for Prerefund Examination
Beginning in January 2022, IRS management decided to double the referral threshold.
Subsequently, in November 2022, the IRS further changed its referral criteria to include only
returns that met specific return scenarios. The threshold and scenarios were used to determine
which returns should be referred for possible prerefund examination and which returns should
have the ERC claim paid. The IRS continued to use these revised criteria through June 2023.
When we asked IRS management why they made these changes, they stated the changes were
intended to deal with the influx of ERC claims and expedite the processing of ERC claims.
However, these decisions led to hundreds of thousands of returns with billions of dollars in ERC
claims not being considered for possible prerefund examination.
Increased thresholds resulted in $19.5 billion in unreviewed ERC
From January 6, 2022, through June 29, 2023, the IRS doubled its normal threshold for the
Accounts Management function to refer ERC claims for possible examination. However, our
review of more than 1.9 million ERC claims processed by the IRS during that time frame
identified 139,993 Tax Years 2020 and 2021 claims for $19.5 billion in the ERC that exceeded the
IRS’s original threshold but were below the IRS’s updated threshold. As a result, these ERC
claims were not referred for possible prerefund examination. We estimate that $824 million in
refundable ERC and $135.5 million in nonrefundable ERC may have been allowed because of the
IRS‘s increased thresholds.
Further refinements of referral criteria resulted in $22.3 billion in the ERC that bypassed
possible prerefund examination
From November 7, 2022, through June 29, 2023, the IRS further limited referrals of ERC claims
for possible prerefund examination by only requiring review of two of the 11 test scenarios
developed to identify potentially erroneous ERC claims. According to the IRS, the shift to these
two tests served to strengthen the referral criteria and limit referrals to potentially questionable
returns. Thus, the only ERC claims referred were cases that failed one of the two specified tests.

Page 8
Management Took Actions to Address Erroneous Employee Retention
Credit Claims; However, Some Questionable Claims Still Need to Be Addressed
Our review of more than 1.9 million ERC claims processed by the IRS during the same time
frame identified 44,930 Tax Years 2020 and 2021 ERC claims totaling $22.3 billion that exceeded
the IRS’s updated threshold for referral and passed the two specified test scenarios. These ERC
claims were neither referred for possible prerefund examination nor tested on the remaining
nine scenarios developed to identify potentially erroneous ERC claims. We estimate that
$948.3 million in refundable ERC and $149 million in nonrefundable ERC may have been allowed
because of the IRS’s limited referral criteria.
Recommendation 2 (E-Mail Alert): On February 28, 2024, we alerted the ERC Team Lead of
our concern and recommended that the IRS review the 139,993 and 44,930 Tax Years 2020 and
2021 returns and consider them for post-refund compliance to recover any potentially
erroneous ERC paid.

Management’s Response to E-Mail Alert: IRS management partially agreed with the
recommendation. The Small Business/Self-Employed Division will check all returns
processed with the ERC for potentially excessive or improper payment under its
recapture program. The IRS cannot agree that the 139,993 and 44,930 Tax Years 2020
and 2021 returns included potentially erroneous ERC paid simply because the returns did
not meet the referral criteria. The IRS will consider additional post-refund compliance
actions to recover potentially erroneous or excessive ERC paid after assessing competing
priorities, available resources, and time remaining on the statute of limitations.

Office of Audit Comment: We understand that the IRS has competing priorities
and limited resources. The tax returns we identified were not previously
considered for prerefund examination by the IRS before the associated ERC
claims were paid. This occurred because management changed the referral
threshold and scenarios as a way to deal with the increased number of ERC
claims. As a result, these tax returns present a significant risk to tax
administration because the IRS now has to try and recover the funds that were
already paid. Using the IRS’s examination rates for ERC claims, we estimated that
more than $2 billion in erroneous ERC may have been potentially paid in
error. Therefore, the IRS should prioritize and review those returns where the
statute remains.
Management Implemented Several Initiatives That Assessed or Prevented
Erroneous Employee Retention Credit Amounts
Because ERC claims are paper filed, the IRS developed a process for capturing key data to
analyze the backlogged inventory. The IRS had employees manually transcribe data from each
ERC claim while it worked on a more efficient and accurate technology solution that allowed for
systemic transcription of key data elements. The captured data were analyzed by the IRS’s
Research, Applied Analytics, and Statistics function to evaluate the potential risk of questionable,
invalid, potentially ineligible, or overstated claims. Beginning February 9, 2024, the IRS
exclusively used the technology solution to transcribe ERC claims.
A team of cross-functional IRS employees, referred to as the ERC team, explored options and
initiatives to assess or prevent erroneous ERC amounts. Figure 4 lists each initiative, the date it
was announced publicly, and the amounts prevented or assessed by each initiative.

As shown in Figure 4, these initiatives have prevented $1.6 billion and assessed $573 million in
the ERC as of April 13, 2024.
Entity-level disallowance letters
The IRS identified 16,185 entities that were ineligible for the ERC and had unprocessed returns
with the ERC as of September 14, 2023. The IRS determined that these entities were ineligible
because either the entity was established after December 31, 2021, or because the entity had no
employees who were paid during an eligible period. As of April 13, 2024, the IRS sent letters to
13,802 of the 16,185 entities.14 The IRS has yet to report the amount of erroneous ERC claims
that were prevented through the disallowance letters. However, based upon data available for
3,669 entities, we estimate that the IRS has prevented at least $1.3 billion in erroneous ERC
claims.15
Moreover, our review of unprocessed ERC claims on Forms 941-X as of September 14, 2023,
identified an additional 923 entities that were not initially identified by the IRS. This includes:
•
873 entities claiming the ERC of $100.8 million ($90.4 million refundable and
$10.4 million nonrefundable) with no employees who were paid during Tax Years 2019
through 2021.
•
50 entities claiming the ERC of $4.2 million ($3.9 million refundable and
$312,802 nonrefundable) that were established after December 31, 2021.

13 While not yet assessed, the IRS reports it received 2,609 VDP applications disclosing over $1 billion in the ERC.
14 The disallowance of the ERC and adjustments to each entity’s tax account is a manual process that is generally
completed by the same employees who assist taxpayers via IRS telephone lines. The IRS’s focus during the
2024 Filing Season has been to deliver the required level of service on the telephone.
15 The erroneous ERC amounts are only available for returns that were transcribed by the IRS. Amounts reported are
subject to the amounts being transcribed correctly.

Page 10

Credit Claims; However, Some Questionable Claims Still Need to Be Addressed
We shared the 923 entities that we identified with IRS management and asked that they review
these cases to determine if they should be disallowed. IRS management agreed that the ERC
claims associated with these entities should be disallowed. In addition, management performed
a subsequent analysis on these entities and found that the claims were categorized as very
high-risk/unprocessable. As a result, the IRS plans to issue these entities a disallowance letter.
However, the IRS has not finalized its plans for issuing the letters.
Recommendation 3: The Commissioner, Small Business/Self-Employed Division, should ensure
that the 923 entities we identified receive a disallowance letter to prevent erroneous ERC claims
from being paid.

Management’s Response: IRS management agreed with the recommendation and had
previously identified these entities. The Small Business/Self-Employed Division will
provide Taxpayer Services with a list of the 923 modules to be issued disallowance
letters.
Withdrawal requests
As of April 13, 2024, the IRS reports it received 6,125 withdrawal requests for 3,602 entities.16 Of
the 6,125 withdrawal requests, the IRS closed 5,123 (84 percent) preventing $341 million in
erroneous ERC. The remaining 1,002 withdrawal requests were not yet closed by the IRS as of
April 13, 2024. As previously mentioned, the withdrawal process is for those taxpayers whose
ERC has not been paid yet, or who received a check but have not yet cashed or deposited it.
Claims that are withdrawn will be treated as if they were never filed.
To be eligible for the withdrawal process, the business must have:
•
Filed an adjusted employment tax return, such as Form 941-X, claiming only the ERC.
•
Faxed a signed and dated copy of the adjusted return, with the words “withdrawn” in the
left margin, and the name and title of an authorized person in the right margin of the
first page.17
Processing the withdrawal requests is a manually intensive process. The withdrawal requests are
generally submitted via a dedicated fax line and delivered as electronic images to a shared drive.
Imaging software is used to create a new case in the Correspondence Imaging Inventory
database with a priority and category code. They are then assigned to an IRS employee who
reviews the documentation to verify basic eligibility requirements are met and captures key data
in a tracking spreadsheet. In addition, the IRS employee is required to input certain transaction
codes on the entity’s tax account to show if the withdrawal was accepted/rejected and to release
any refund freezes. With this being such a manual process, it is subject to human error.

16 Generally, a business files four quarterly employment tax returns each year. Thus, a business may withdraw
multiple tax forms claiming the ERC.
17 An authorized person depends on the type of business. For example, for a sole proprietorship, the individual who
owns the business can sign. For a corporation, the president or vice-president may sign for the business.

Credit Claims; However, Some Questionable Claims Still Need to Be Addressed
We evaluated a statistically valid sample of 89 withdrawal requests processed by the IRS from
November 13, 2023, through December 2, 2023.18 Our review found that IRS employees made
some errors when recording information in the tracking spreadsheet. For example, an employee
entered an incorrect date or understated the amount of the ERC withdrawn. In addition,
employees did not always take required actions when processing the withdrawal requests. For
example, they failed to enter required notes or transaction codes on the entity’s tax account.
Although the IRS generally made the correct determination when accepting or rejecting the
withdrawal, incorrect tracking affects the IRS’s ability to report complete and accurate
information about the withdrawal program.
We shared our concern about employee errors with IRS management and asked if management
considered whether they would complete their own quality reviews of ERC withdrawal requests.
Management Action: In response to our raising this concern, IRS management implemented a
weekly targeted review of ERC withdrawal requests and shared feedback with employees who
made mistakes processing the withdrawal requests. According to the IRS, steps were also taken
to correct the mistakes that were identified. The IRS’s own review has also identified concerns
with errors. As of April 13, 2024, IRS management’s review of 220 processed withdrawal
requests identified that 62 (28 percent) contained errors.
Recapture letters
As of April 13, 2024, the IRS mailed Letter 6577 to 12,408 businesses assessing $572.9 million in
potentially erroneous ERC previously paid for 22,072 Tax Year 2020 ERC returns. Figure 5
provides a summary of the results of the recapture letters for the 22,072 ERC returns.
Figure 5: Summary of Recapture Letter Results

Source: Information provided by the IRS’s ERC team (data as of April 13, 2024).
We asked the IRS why 15 percent of the recapture letters sent to businesses resulted in the ERC
claim being fully allowed.19 IRS management explained that the data used to identify the
number of Forms W-2 filed by the employer sometimes did not include an accurate count for
that employer. This can occur when a Form W-2 is filed late, or the Form W-2 was furnished to
the employee but not the IRS. We also asked IRS management if they planned to update the
strategy or methodology for identifying businesses for recapture for subsequent tax years.

18 Our sample was selected using a 95 percent confidence interval, 50 percent error rate, and ±10 percent precision
factor.
19 In Tax Year 2021, the IRS reported a 7 percent no-change rate for employment tax return examinations.

Page 12
Management Took Actions to Address Erroneous Employee Retention
Credit Claims; However, Some Questionable Claims Still Need to Be Addressed
IRS management stated they updated their strategy to include a secondary source for analysis
of Forms W-2 prior to contacting the taxpayer; however, the strategy was not available at the
time we concluded our review. Therefore, we could not verify IRS management’s assertion.
Recommendation 4: The Commissioner, Small Business/Self-Employed Division, should ensure
that any subsequent analysis to identify businesses for recapture letters uses accurate wage data
and takes into consideration lessons learned from the Tax Year 2020 recapture letters.

Management’s Response: IRS management agreed with the recommendation. The
Small Business/Self-Employed Division will ensure that the strategy for identifying
businesses for recapture for subsequent years is updated to include a secondary source
for analysis of Form W-2 data prior to contacting the taxpayer.
The VDP
The ERC VDP was open from December 21, 2023, through March 22, 2024. To apply for the ERC
VDP, employers submitted Form 15434, Application for Employee Retention Credit (ERC)
Voluntary Disclosure Program, online via the IRS’s Document Upload Tool. According to the IRS,
through March 22, 2024, it received 2,609 applications disclosing over $1 billion in the ERC.
However, the IRS does not have any data yet to show how many applicants repaid and the
amount of their repayment i.e., paid in full or on a payment plan.
As of April 17, 2024, the IRS has processed two applications. We reviewed both applications and
did not find any concerns with the IRS’s processing of these applications.
Other initiatives were implemented during Calendar Year 2024
The IRS also implemented other initiatives during Calendar Year 2024. According to the IRS, the
purpose of these initiatives was to collect data on taxpayer compliance and to determine how
businesses respond to the notices, which will help inform the IRS’s future compliance plans.
•
Prerefund audits. The week of January 15, 2024, the IRS mailed 500 Letters 6612,
Pre-Refund ERC Claim Examination. The businesses were selected at random, with a few
exclusions from unprocessed amended ERC returns that were received by the IRS prior to
September 14, 2023.20 These businesses claimed refunds totaling $80.8 million for
1,736 tax periods. As of April 13, 2024, the IRS reported it has received responses from
273 businesses. Of the remaining 227 letters that were sent, 166 businesses have not yet
responded, 51 businesses requested an extension, and the remaining 10 businesses had
their cases closed without an examination.
The IRS completed a quality review of 173 of the 273 businesses that provided a
response to Letter 6612. The 173 responses addressed 551 tax periods. Figure 6 shows
the percentage and dollar amounts of prerefund audit dispositions for all 551 tax periods
as of April 13, 2024.

20 Exclusions included returns already selected for further review, third-party payers, churches, and withdrawn claims.

Figure 6: Prerefund Audit Dispositions

Source: TIGTA graphic based upon information provided by the IRS’s ERC team.
As shown in Figure 6, the IRS has provided most businesses with an additional opportunity to
substantiate the ERC reported by requesting additional records. Therefore, the number of audits
that will result in full disallowance is currently unknown.
•
Educational notices. On February 9, 2024, the IRS mailed CP 271, Pre-refund Compliance
Notice, to 2,990 businesses. Like the prerefund audits, these businesses were selected at
random, with a few exclusions, from unprocessed amended returns with the ERC that
were received by the IRS prior to September 14, 2023. The letter asks the business to
confirm it is entitled to the ERC claimed, by reviewing the abbreviated checklist provided
in the letter. If the business determines it is entitled to the ERC, no action is needed. If
the business determines it is not entitled to the ERC, the business is encouraged to
withdraw its claim following the instructions provided in the letter. As of April 17, 2024,
the IRS reports 42 businesses have withdrawn their ERC claims totaling $1.1 million.
When asked if they had plans to send additional notices, IRS management initially
indicated that they did not and instead would focus their efforts on their other
compliance initiatives. However, we suggested that they consider sending these
educational notices to targeted risk populations, instead of at random, to increase their
effectiveness.
Management Action: As of April 11, 2024, IRS management indicated they will consider
educational notices for other targeted risk populations.
•
Educational sessions hosted by IRS’s Criminal Investigation (CI). On January 25, 2024, the
IRS announced that CI would host educational sessions for preparers. CI mailed
220 letters to preparers inviting them to a session at a location near them on a specific
date/time. These sessions were hosted at IRS field offices across the country from
February 12, 2024, through February 16, 2024. In general, the preparers that were
identified were associated with numerous tax return filings with ERC claims. CI reports
that 123 (56 percent) preparers responded with 116 confirming attendance and seven
declining the invitation. The remaining 97 (44 percent) preparers did not respond to the
letter. As of April 25, 2024, CI stated that it plans to study the impact of these
educational sessions and whether there were behavioral changes made by these
preparers in the coming years.

Future of the ERC
The ERC team worked with the IRS’s Research, Applied Analytics, and Statistics function to
evaluate the risk of erroneous ERC payments. Specifically, by evaluating the quality and the
amount of ERC claims to identify the potential risk factors based on different characteristics of
the business or found on the return itself. The ERC team is using this information to help guide
its decisions and to continue to refine and finalize its compliance plans. The ERC team
completed its initial evaluation of potential risk factors in June 2024.
In August 2024, the IRS announced additional actions to help businesses and prevent improper
payments in the ERC program, including to accelerate more payments. Specifically, the IRS
stated it will now start processing the highest and lowest risk claims filed between
September 14, 2023, and January 31, 2024. Moreover, the IRS announced that it was reopening
the VDP, through November 22, 2024, for the ERC claimed during Tax Year 2021. As of
September 2024, the moratorium remains in effect for claims received after January 31, 2024.
The ERC team will continue to work with the Research, Applied Analytics, and Statistics function
to refine and update the potential risk factors to determine how to work the remaining ERC
inventory
Delays in processing ERC claims may impact legitimate businesses that are eligible for the ERC
and could result in increased interest paid by the IRS to these businesses, if a determination is
made that the ERC claim is legitimate. The ERC team is working with the Office of Servicewide
Interest to calculate the amount of estimated credit interest that could potentially be paid
because of the delayed processing of ERC claims.21 The ERC team is using these estimates to
compare the risk of paying potentially erroneous ERC claims to the potential amounts of interest
paid as it moves forward with its decisions on how to work the inventory. According to the IRS’s
estimates, the moratorium and additional time taken to analyze and process ERC claims will be a
cost savings to the Government, i.e., the IRS will pay less in interest on the legitimate claims
when compared to the claims identified as high risk and likely erroneous.
Finally, on January 31, 2024, the U.S. House of Representatives passed legislation which would
have prevented any credit or refund for the ERC for any claim filed after January 31, 2024.22 The
legislation would have also extended the assessment statute of limitation for ERC claims to six
years. However, as of September 2024, the legislation has not advanced further. IRS
Commissioner Werfel has publicly commented that the legislation would be helpful in the IRS’s
administration of the ERC.23

21 For ERC interest estimates, interest was calculated from the normal due date of the original return to an estimated
overpayment refund date. Additionally, for amended returns processed within 45 days of receipt, interest on the
overpayment generally stops accruing on the amended return received date – Internal Revenue Code § 6611(e)(2).

Appendix I
Detailed Objective, Scope, and Methodology
The overall objective of this audit was to assess the IRS’s processes to ensure the accuracy of
both original and amended returns with the ERC, and the IRS’s compliance initiatives to prevent
or recover erroneous ERC. To accomplish our objective, we:
•
Determined if the new eligibility checklist was accurate, complete, and streamlined for
taxpayers.
•
Determined whether the processes to identify potentially fraudulent original returns were
working as intended during Calendar Year 2023.
•
Met with IRS management to discuss their efforts to prevent or recover erroneous ERC
and any new compliance initiatives they were considering.
•
Assessed each of the IRS’s new compliance initiatives, including the withdrawal option,
the VDP, entity disallowance letters, recapture letters, educational notices, prerefund
audits, and CI educational visits for accuracy and effectiveness.
•
Reviewed a statistically valid stratified sample of 89 ERC withdrawal requests from the
population of 932 ERC withdrawal requests processed by the IRS and determined
whether the withdrawal requests were correctly processed and tracked. Our stratified
sample was selected using a 95 percent confidence interval, a 50 percent error rate, and
a ± 10 percent precision factor. We used a statistical sample because we planned to
project the population. TIGTA’s contract statistician assisted with developing the
sampling plan.
•
Determined whether inconsistent and changing referral criteria resulted in potentially
fraudulent ERC being processed and paid.
Performance of This Review
This review was performed at the Cincinnati, Ohio, and Ogden, Utah, Accounts Management
locations during the period July 2023 through April 2024. We conducted this performance audit
in accordance with generally accepted government auditing standards. Those standards require
that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a
reasonable basis for our findings and conclusions based on our audit objective. We believe that
the evidence obtained provides a reasonable basis for our findings and conclusions based on
our audit objective.
Major contributors to the report were Diana Tengesdal, Assistant Inspector General for Audit
(Returns Processing and Account Services); Linna Hung, Director; Jeffrey Cullum, Audit Manager;
Jaclynne Durrant, Lead Auditor; Van Warmke, Senior Auditor; Hee Koo Kang, Auditor; and
Sandy Ramos, Auditor.

Data Validation Methodology
During this review, we obtained data extracts from the following:
•
TIGTA’s Data Center Warehouse: Accounts Management Services, Business Master File,
Business Tax Return File, and the Correspondence Imaging Inventory.
•
The IRS’s Compliance Data Warehouse: Form 94X Accepted and Rejected Files,
Form 94X-X Transcribed Data, Business Transaction History, and Small Business
Administration Payment Protection Program Loan Data.
•
The IRS’s ERC Shared Drive: ERC Withdrawal Claims and VDP Applications.
Before relying on the data, we ensured that each file contained the specific data elements we
requested. In addition, we selected judgmental samples of each extract and verified that the
data in the extracts were the same as the data captured in IRS systems, such as the Integrated
Data Retrieval System. We also performed analysis to ensure the validity and reasonableness of
our data, such as ranges of dollar values and obvious invalid values. We determined that the
data were sufficiently reliable for purposes of this report.
Internal Controls Methodology
Internal controls relate to management’s plans, methods, and procedures used to meet their
mission, goals, and objectives. Internal controls include the processes and procedures for
planning, organizing, directing, and controlling program operations. They include the systems
for measuring, reporting, and monitoring program performance. We determined that the
following internal controls were relevant to our audit objective: IRS management’s processes for
preventing erroneous ERC and identifying/recapturing erroneous ERC paid, and management’s
assessment of identifying low-, medium-, and high-risk ERC returns. We tested these internal
controls by discussing IRS management’s initiatives with them to understand the thought
processes and requesting/reviewing all documentation related to each of IRS management’s
compliance initiatives to ensure that the logic was reasonable and fair.

Appendix II
Outcome Measures
This appendix presents detailed information on the measurable impact that our recommended
corrective actions will have on tax administration. These benefits will be incorporated into our
Semiannual Report to Congress.
Type and Value of Outcome Measure:
•
Cost Savings (Funds Put to Better Use) – Potential; $19,087,019 in potentially erroneous
refundable ERC claimed on 976 of the 997 tax returns that met updated identity theft
filter criteria and should be part of a post-refund review (see Recommendation 1).1
Methodology Used to Measure the Reported Benefit:
The IRS implemented three ERC identity theft filters. Using the IRS’s filter criteria as of
July 18, 2023, we replicated the three filters by querying the Business Return Transaction File as
of July 20, 2023, for Forms 941 claiming the ERC during PYs 2021 through 2023. Our analysis
identified 1,961 Forms 941 that met one or more of the updated identity theft filters but were
not identified by the IRS because the updated filter criteria was not in place when these returns
were processed. In addition, to be conservative, we also identified any transaction codes posted
to the Business Master File Other Transactions Table as of October 26, 2023, that could reflect
the potential for post-refund examinations or adjustments. As a result, we limited our results to
976 of the Forms 941 claiming $19,087,019 in refundable ERC.
Type and Value of Outcome Measure:
•
Revenue Protection – Potential; $544,285 in potentially erroneous nonrefundable ERC
claimed on 773 of the 997 tax returns that met updated identity theft filter criteria and
should be part of a post-refund review (see Recommendation 1).
Methodology Used to Measure the Reported Benefit:
The IRS implemented three ERC identity theft filters. Using the IRS’s filter criteria as of
July 18, 2023, we replicated the three filters by querying the Business Return Transaction File as

not identified by the IRS because the updated filter criteria was not in place when these returns
were processed. In addition, to be conservative, we also identified any transaction codes posted
to the Business Master File Other Transactions Table as of October 26, 2023, that could reflect
the potential for post-refund examinations or adjustments. As a result, we limited our results to
773 Forms 941 claiming $544,285 in nonrefundable ERC.

1 Since a taxpayer may claim both a refundable and nonrefundable ERC amount, the total number of tax returns,
Forms 941-X, and entities will not be equal in each set of outcome measures presented in Appendix II.

Page 18
Management Took Actions to Address Erroneous Employee Retention
Credit Claims; However, Some Questionable Claims Still Need to Be Addressed
Type and Value of Outcome Measure:
•
Cost Savings (Funds Put to Better Use) – Potential; $1,772,359,718 in refundable ERC
claimed on 182,717 of the 184,923 Forms 941-X for Tax Years 2020 and 2021 that were
not considered for possible examination due to changing referral criteria (see
Recommendation 2).
Methodology Used to Measure the Reported Benefit:
The IRS doubled the threshold for its examination referral criteria for Accounts Management
employees processing Forms 941-X with the ERC and changed its criteria to include only returns
that met specific return scenarios when considering potential referral. Specifically, our review
identified:
•
138,415 amended returns with refundable ERC of $16,714,212,232 processed by the IRS
between January 6, 2022, and June 29, 2023, that exceeded the IRS’s original threshold
but was below the IRS’s updated threshold. The IRS’s referral data from January 2022
(prior to changes discussed in the report) showed that *****2***** of returns referred
were selected. In addition, Fiscal Year 2024 examination closure results as of
April 11, 2024, showed that *****2***** of all closed ERC examinations resulted in a full
disallowance of the ERC. Based upon this, we estimate that $824,010,663
($16,714,212,232 x *****2***** x *****2*****) in refundable ERC may have been allowed
because of the IRS doubling its threshold and not considering these returns for possible
examination, as it had previously.
•
44,302 amended returns with refundable ERC of $19,236,289,147 processed by the IRS
between November 7, 2022, and June 29, 2023, that met the IRS’s updated threshold for
referral but were not tested on nine scenarios developed to identify potentially
erroneous ERC or referred for possible examination. The IRS’s referral data from
January 2022 (prior to changes discussed in the report) showed that *****2***** of
returns referred were selected. In addition, Fiscal Year 2024 examination closure results
as of April 11, 2024, showed that *****2***** of all closed ERC examinations resulted in a
full disallowance of the ERC. Based upon this, we estimate that $948,349,055
($19,236,289,147 x *****2***** x *****2*****) in refundable ERC may have been allowed
because of the IRS limiting its referral criteria to specific potentially erroneous ERC
scenarios.
$1,772,359,718 = $824,010,663 + $948,349,055.

Management’s Response: IRS management disagreed with this outcome. All returns
processed with the ERC will be checked for potentially excessive or improper payment
under their recapture program. The IRS will consider additional post-refund compliance
actions after assessing competing priorities, available resources, and time remaining on
the statute of limitations. The IRS cannot determine the corresponding dollar amounts
until appropriate actions are taken to review and address the Forms 941-X.

Page 19

approximately $1.8 billion in cost savings is contingent upon the IRS’s ability to
review the potentially excessive or improper payments as part of its post-refund
compliance activities and on the extent that taxpayers can adequately
substantiate these claims once contacted.
Type and Value of Outcome Measure:
•
Revenue Protection – Potential; $284,551,288 in nonrefundable ERC claimed on 168,836
of the 184,923 Forms 941-X for Tax Years 2020 and 2021 that were not considered for
possible examination due to changing referral criteria (see Recommendation 2).
Methodology Used to Measure the Reported Benefit:
The IRS doubled the threshold for its examination referral criteria for Accounts Management
employees processing Forms 941-X with the ERC and changed its criteria to include only returns
that met specific return scenarios when considering potential referral. Specifically, our review
identified:
•
127,581 amended returns with nonrefundable ERC of $2,748,745,346 processed by the
IRS between January 6, 2022, and June 29, 2023, that exceeded the IRS’s original
threshold but was below the IRS’s updated threshold. The IRS’s referral data from
January 2022 (prior to changes discussed in the report) showed that *****2***** of
returns referred were selected. In addition, Fiscal Year 2024 examination closure results
as of April 11, 2024, showed that *****2***** of all closed ERC examinations resulted in a
full disallowance of the ERC. Based upon this, we estimate that $135,513,146
(2,748,745,346 x *****2***** x *****2*****) in nonrefundable ERC may have been allowed
because of the IRS doubling its threshold and not considering these returns for possible
examination, as it had previously.
•
41,255 amended returns with nonrefundable ERC of $3,023,086,045 processed by the IRS
between November 7, 2022, and June 29, 2023, that met the IRS’s updated threshold for
referral but were not tested on nine scenarios developed to identify potentially
erroneous ERC or referred for possible examination. The IRS’s referral data from
January 2022 (prior to changes discussed in the report) showed that *****2***** of
returns referred were selected. In addition, Fiscal Year 2024 examination closure results
as of April 11, 2024, showed that *****2***** of all closed ERC examinations resulted in a
full disallowance of the ERC. Based upon this, we estimate that $149,038,142
($3,023,086,045 x *****2***** x *****2*****) in nonrefundable ERC may have been allowed
because of the IRS limiting its referral criteria to specific potentially erroneous ERC
scenarios.
$284,551,288 = $135,513,146 + $149,038,142.

Office of Audit Comment: As management noted in its response, administering
the ERC was complex and resource intensive. Our outcome measure illustrates
the impact on tax administration of ERC claims that were not considered for
examination due to changing referral criteria. The actual amount of the
approximately $285 million in revenue protection is contingent upon the IRS’s
ability to review the potentially excessive or improper payments as part of its
post-refund compliance activities and on the extent that taxpayers can
adequately substantiate these claims once contacted.
Type and Value of Outcome Measure:
•
Cost Savings (Funds Put to Better Use) – Potential; $94,302,374 in refundable potentially
erroneous ERC claimed by 852 of the 923 entities that should have received a
disallowance letter but were not initially identified by the IRS (see Recommendation 3).
Methodology Used to Measure the Reported Benefit:
The IRS identified entities that should receive an ERC disallowance letter and provided TIGTA
with its criteria for identifying these entities and a list of entities identified. Using the IRS’s
criteria, we identified Forms 941-X reporting the ERC from the Correspondence Imaging
Inventory that was received by the IRS as of September 14, 2023. These returns were limited to
tax periods ending June 30, 2020, through December 31, 2021. Using Business Master File data,
we limited our results to entities that were established after the ERC eligibility period,
i.e., December 31, 2021. We also analyzed Forms W-2 filed for Tax Years 2019, 2020, and 2021
to determine whether the entities were eligible to claim the ERC. We then compared our
population to the population provided by the IRS and identified 50 entities established after
December 31, 2021, and 873 entities with returns for the ERC that had no Forms W-2 filed, that
were not initially identified by the IRS, and that did not receive an ERC disallowance letter. We
identified a total of 923 entities (50 + 873) with 852 entities claiming refundable ERC totaling
$94,302,374.
Type and Value of Outcome Measure:
•
Revenue Protection – Potential; $10,712,328 in nonrefundable potentially erroneous ERC
claimed by 686 of the 923 entities that should have received a disallowance letter but
were not initially identified by the IRS (see Recommendation 3).
