Summary

A final audit report issued September 2, 2021 by the Treasury Inspector General for Tax Administration, Report Number 2021-46-064, on the IRS's actions to address the backlog of unworked inventory affecting business taxpayers after Tax Processing Center closures. It reports the IRS closed its Tax Processing Centers nationwide as of April 6, 2020 and that Treasury extended filing and payment deadlines to July 15, 2020. It finds more than 7.9 million paper-filed business returns still needed processing as of the week ending December 31, 2020, compared with 239,285 as of December 31, 2019. It also finds the IRS erroneously assessed 211 Failure to Pay penalties totaling $45,451 and incorrectly assessed 1,256 estimated tax penalties. The report makes two recommendations, which IRS management agreed with.

HIGHLIGHTS:  Effects of the COVID-19 Pandemic on Business Tax Return Processing Operations 
Final Audit Report issued on September 2, 2021 
Report Number 2021-46-064 
 
 
Why TIGTA Did This Audit 
This audit was initiated to provide 
selected information related to 
the IRS’s 2020 Filing Season, 
including information related to 
the impact of the Coronavirus 
Disease 2019 (COVID-19).  The 
overall objective of this review 
was to assess the IRS’s actions to 
address the backlog of unworked 
inventory affecting business 
taxpayers as a result of Tax 
Processing Center closures. 
Impact on Taxpayers 
In response to COVID-19, the IRS 
took unprecedented and drastic 
actions to protect the health and 
safety of its employees and the 
taxpaying public.  These actions 
included closing its Tax 
Processing Centers nationwide as 
of April 6, 2020. 
In addition, on April 9, 2020, the 
Department of the Treasury 
extended the Federal income tax 
filing due date for various tax 
filing and payment deadlines that 
occurred starting on April 1, 2020, 
to July 15, 2020.  As a result, 
affected businesses had until 
July 15, 2020, to file returns and 
pay any taxes that were originally 
due during this period. 
 
 
 
 
 
 
 
 
 
 
What TIGTA Found 
The closure of Tax Processing Centers created a significant backlog of 
business tax returns, correspondence, and other types of business 
taxpayer-related work that needed to be processed.  As of the week 
ending December 31, 2020, the IRS had more than 7.9 million 
paper-filed business returns that still needed to be processed.  In 
comparison, the IRS had 239,285 paper-filed business returns that 
were in process as of December 31, 2019. 
Some penalties were inappropriately assessed due to delays  
in processing payments or tax forms.  For example, the IRS 
erroneously assessed 211 Failure to Pay penalties totaling $45,451 
due to a programming error.  The IRS also incorrectly assessed 
1,256 estimated tax penalties from April 1, 2020, through 
December 31, 2020.  The IRS submitted an information technology 
work request on July 15, 2020, to update penalty processing, but the 
programming was not implemented until January 2021.  As a result, 
estimated tax penalties assessed for business taxpayers with tax years 
ending between April 2020 and December 2020 and filed before 
January 2021 had penalties calculated without considering the relief. 
In addition, systemic payment processing limitations caused further 
delays in processing payments.  The IRS’s system was limited to 
processing payments that were received within 30 days or less.  
However, upon the June 2020 reopening of the Tax Processing 
Centers, most payments exceeded this limit.  The IRS did not revise 
the limit until October 1, 2020, because it was unaware that the 
programming could be changed. 
Finally, redirecting more payments to the lockbox sites could 
facilitate reducing the backlog.  While the majority of paper 
payments are directed to a lockbox location, more than 6.9 million 
payments totaling more than $37.6 billion were processed at the 
IRS’s Tax Processing Centers during Fiscal Year 2020.  This includes 
more than 339,000 payments totaling $3.4 billion received by IRS 
field office employees. 
What TIGTA Recommended 
TIGTA recommended that the Commissioner, Wage and Investment 
Division, ensure that the incorrectly assessed estimated tax penalties 
are corrected, and evaluate the feasibility to direct additional types of 
payments from Tax Processing Centers to lockbox sites. 
IRS management agreed with both recommendations.  Corrections 
were made to the incorrectly assessed estimated penalties.  The 
Lockbox Electronic Network Imaging Functional Specification 
Package has been updated to include processing capability for 
several additional notices.  Analysis of the volumes of notices is being 
performed to determine if all notices can be directed to lockbox sites.  
However, management determined it was not feasible for payments 
received in field offices to be directed to lockbox sites.

Effects of the COVID-19 Pandemic on Business Tax Return Processing Operations 
Background 
As we previously reported, the Internal Revenue Service (IRS) took unprecedented and drastic 
actions in response to the Coronavirus Disease 2019 (COVID-19) pandemic to protect the health 
and safety of its employees and the taxpaying public.1  This included closing its Tax Processing 
Centers, Taxpayer Assistance Centers, and other offices nationwide.2  The backlog of returns, 
correspondence, and other types of work resulting from the pandemic has and will continue to 
have a significant impact on the associated business taxpayers.  Figure 1 provides a comparison 
of business tax return inventory levels in various stages of processing that the IRS normally 
carries into a new calendar year compared to inventory levels carried into Calendar Year 2021.

The Department of the Treasury extended the income tax filing due date 
To assist businesses impacted by COVID-19, the Department of the Treasury extended the 
Federal income tax filing due date and permitted taxpayers to defer Federal income tax

Effects of COVID-19 on Tax Processing Operations (Mar. 2021). 
2 All IRS Taxpayer Assistance Centers were closed as of March 23, 2020, and all Tax Processing Centers were closed as 
of April 6, 2020.  The Tax Processing Centers were re-opened in June 2020. 
3 Tax returns identified with an error condition are suspended from processing and sent to a tax examiner for 
correction. 
4 Tax returns that cannot be processed, usually due to missing or incomplete information.  Tax examiners correspond 
with the taxpayer to clarify an entry on a return.  When the taxpayer responds, the tax examiner will resolve the issue 
and the return will continue processing. 
5 Transactions that will not post to the taxpayer’s account because they failed validity checks.  The unpostable 
condition must be resolved in order to complete processing of the transaction. 
6 Corrected tax returns filed that are either being worked by the Submission Processing or Accounts Management 
functions.

payments.  On April 9, 2020, tax relief was granted that postponed various tax filing and 
payment deadlines that occurred starting on April 1, 2020.  As a result, affected businesses had 
until July 15, 2020, to file returns and pay any taxes that were originally due during this period.  
This includes 2019 individual and business returns normally due on April 15, as well as various 
2019 business returns due on or after April 1, 2020.  Taxpayers were also permitted to defer 
Federal income tax payments due on April 15, 2020, to July 15, 2020, without penalties and 
interest. 
In addition, the following legislation was enacted which included provisions to assist businesses: 
• 
The Families First Coronavirus Response Act,7 enacted on March 18, 2020.  This provides 
businesses with tax credits to cover certain costs of providing employees with paid sick 
leave and expanded family and medical leave for reasons related to COVID-19, from 
April 1, 2020, through December 31, 2020.  Eligible employers can claim these credits on 
their Federal employment tax returns, e.g., Form 941, Employer's QUARTERLY Federal Tax 
Return, or an employer can benefit more quickly by reducing its Federal employment tax 
deposits.  For those employers for which there are insufficient Federal employment taxes 
to cover the amount of the employer’s credit, the employer may request an advance 
payment of the credits from the IRS by submitting Form 7200, Advance Payment of 
Employer Credits Due to COVID-19. 
• 
The Coronavirus Aid, Relief, and Economic Security Act,8 enacted on March 27, 2020, 
included provisions:  to encourage eligible employers to keep employees on their payroll 
with an employee retention tax credit; to allow employers to defer the deposit and 
payment of the employer share of Social Security taxes (Tier 1 employer tax for railroad 
employers); and that made modifications that temporarily repeal certain restrictions 
imposed by the Tax Cuts and Jobs Act 9 affecting net operating losses.10 
• 
The Consolidated Appropriations Act, 2021,11 signed into law on December 27, 2020, 
made changes to the new employer tax credits created in the Families First Coronavirus 
Response Act and the Coronavirus Aid, Relief, and Economic Security Act passed in 
March 2020.  Employers are eligible to continue to claim the Sick and Family Leave 
Credit(s) through March 31, 2021, and the Employee Retention Credit through 
June 30, 2021.

9 Pub. L. No. 115-97, 131 Stat. 2054 (2017). 
10 A net operating loss is created when certain deductions exceed income from all sources.  These deductions must 
relate to a trade or business, work as an employee, or casualty or theft losses.  A net operating loss deduction can be 
applied, or “carried,” to offset taxable income in either preceding or later taxable years.  A net operating loss may 
allow a refund for taxes already paid when carried back to an earlier year.

The American Rescue Plan Act of 202112 was signed on March 11, 2021, further 
extending the Sick and Family Leave Credit to September 30, 2021, and the Employee 
Retention Credit to December 31, 2021. 
TIGTA recently reported on the IRS’s efforts to ensure the validity and accuracy of tentative 
refund applications reporting a carryback loss,13 employer tax credit claims, and the accuracy of 
the employer reconciliations of advance payments.14 
Results of Review 
This report presents the results of our continued assessment of the IRS’s efforts to process 
business tax returns and provide quality customer service to business taxpayers.  Similar to 
delays impacting individual taxpayers, the closure of Tax Processing Centers resulted in a 
significant backlog of unprocessed business tax returns and other types of business tax account 
work.  While much of the IRS’s workforce continues to telework, the work performed at the IRS’s 
Tax Processing Centers is not conducive to a remote telework environment.  This work includes 
the receiving, sorting, and distributing of mail and the processing of paper tax returns, which 
requires manually inputting information from the tax return into IRS systems, correcting errors, 
and corresponding with the taxpayer, if needed.  Although the Tax Processing Centers are 
currently open, the IRS was not always able to operate at full capacity due to social distancing 
requirements.  These requirements include limiting close contact with other employees and 
maintaining a physical distance of at least six feet.  In addition, as we reported previously, a 
significant number of employees remained on weather and safety leave.  However, beginning 
October 13, 2020, the IRS required medical documentation from those employees claiming high 
risk. 
Unlike individual tax return filers, business taxpayers file various tax return types with different 
filing due dates.  As a result, business tax returns continue to be filed further increasing 
backlogs.  Figure 2 provides a summary of select business tax return types and their associated 
due dates.  With the exception of those tax returns that are filed each quarter, the due dates are 
based on taxpayers that file a calendar year return.15

In an effort to address inventory backlogs, the IRS increased employee telework capability, 
provided incentive pay for employees, and offered overtime.  The IRS also transshipped 
unopened mail from the Kansas City, Missouri, and Ogden, Utah, Tax Processing Centers, to the 
Louisville, Kentucky, or Cincinnati, Ohio, lockbox22 sites.  For example, from October 14, 2020, to 
December 14, 2020, the IRS transshipped more than 2 million pieces of unopened mail items to 
these lockbox sites.  The lockbox sites sorted the mail and processed 103,173 payments totaling 
almost $328 million associated with this unopened mail.  The IRS stated that it used this process 
to help it work through the backlog of unopened mail.  Further, the IRS indicated that the mail 
returned from the lockbox sites was sent to the second sort function, thus bypassing the 
extraction and initial sort functions. 
Further, as we have reported, the IRS continues to have difficulty hiring sufficient staff needed to 
continue to work backlog inventory and process Tax Year 2020 tax returns.23  The inability of the

Finally, tax examiners who had training in business tax returns did not return to work or  
those that returned to work did not have the necessary training to process these returns.  For 
example, in the Code and Edit function at the Kansas City Tax Processing Center, only 41 of the 
74 employees who were trained to process business tax returns returned to work as of 
June 15, 2020.  However, the IRS stated that, as of February 19, 2021, there were 98 employees 
who are now trained to process business tax returns.  We plan to continue to monitor the IRS’s 
efforts to address backlogs of work in its various Submission Processing functions and will 
provide further results in our 2021 Filing Season report.26 
Processing Business Tax Returns 
During Calendar Year 2020, the IRS received approximately 60.6 million business tax returns 
(22.3 million filed via paper and 38.4 million filed electronically).27  When the Tax Processing 
Centers closed, taxpayers still had the ability to continue to electronically file their tax returns.  
Nearly 5.7 million paper returns were processed as of the time Tax Processing Centers were 
closed.  However, once closed, all processing of paper-filed tax returns was halted.  The IRS 
reported that it had about 2.9 million paper-filed business tax returns on-site and unprocessed 
when operations were halted. 
Once operations resumed, the IRS prioritized the processing of the backlog of business returns 
and payments by received date.  For example, in June 2020, Submission Processing function 
management sent the Tax Processing Center staff a document outlining processing priorities for 
                                                 
24 Fiscal Year 2021 Hiring Projections. 
25 In-process employees are defined as the number of candidates with a tentative job offer on an open 
announcement.  Not all will be successfully onboarded.

business tax returns.  This document showed that the staff should focus on processing business 
refund returns and the Heavy Highway Vehicle Use tax return as the number one priority.  The 
Heavy Highway Vehicle Use tax return is filed by owners of highway motor vehicles that are used 
on public highways.  Owners of these vehicles are required to provide proof of payment before 
they can register these vehicles with their State’s Department of Motor Vehicles.  The IRS issued 
five prioritization documents from June 22, 2020, through December 15, 2020.  Figure 5 shows 
the various processing priorities.

September 21, 2020, October 29, 2020, and December 15, 2020. 
In August 2020, Submission Processing management issued an update to the prioritization 
document replacing Form 940 with Form 720.  The excise taxes remitted with the Form 720 are 
deposited into one of many trust funds maintained by the Government.  One such fund is the 
Highway Trust Fund, and monies deposited into this fund are used to invest in and maintain the 
Nation’s highways and bridges.  According to IRS management, they were contacted by 
representatives from the Department of Transportation with an urgent concern regarding the 
Aviation and Highway Trust Funds.  Because of delays processing Forms 720, excise taxes were 
not being credited to these trust funds, thus causing a potential insolvency situation.  This in 
turn caused issues with availability of funding for certain construction projects around the 
country.  The changes in processing priorities at times required staff to re-sort returns in the 
unopened mail, thus causing further delays processing business tax returns. 
On February 4, 2021, IRS management stated that they would not be issuing prioritization 
documents for Filing Season 2021.  Instead, they plan to follow processing priority guidelines 
that use the number of days the IRS expects to process a paper return once received.  IRS 
management indicated that these guidelines are normal for a filing season and focus on 
processing refund returns and prioritizing employment tax returns, e.g., Forms 941, based on tax 
quarter and received date. 
However, on March 23, 2021, IRS management noted that some employment tax returns were 
being processed out of date order.  Further evaluation of the concern identified that the

Kansas City Tax Processing Center had approximately 460,000 Forms 941 that were being held 
from processing.  This often occurs when an employee is unable to complete processing a batch 
of tax returns prior to the end of their shift.  This work should be re-assigned to the next shift 
before assigning them any new batches of tax returns to process.  This did not occur.  IRS 
management indicated that processing these batches and the backlog of Forms 941 are their 
priority.  To facilitate completion of this work, management is exploring assigning some of this 
work to the Fresno, California, and Austin, Texas, Tax Processing Centers. 
Computer programming errors contributed to increasing inventories of tax documents 
that need to be processed 
The Tax Processing Centers identified a high volume of error cases involving Forms 1041 on 
January 28, 2021, and Forms 1065 on February 23, 2021.  The IRS found that programming 
errors were incorrectly identifying all of these returns as having errors requiring manual review 
by the Error Resolution function.  In response, Submission Processing management began 
holding Forms 1041 from data input on January 28, 2021, and Forms 1065 on February 24, 2021, 
to avoid sending additional work to the Error Resolution function and correct the programming 
error.  IRS management stated that the issues had been fixed as of April 5, 2021, and 
April 8, 2021, respectively, and they subsequently released the hold on processing these forms.  
However, this temporary hold resulted in further increasing business tax return backlogs.  
Figure 6 provides a comparison of the IRS’s reported volumes of Forms 1065 and 1041 to be 
processed as of March 27, 2021, with inventory as of December 31, 2020.

Due to backlogs, management decided to destroy information returns and delay 
processing others 
We continue to perform on-site walkthroughs at the Ogden Tax Processing Center and meet 
with staff to discuss challenges they are facing while addressing these ongoing backlogs of 
inventory.  During our walkthrough of the Ogden Tax Processing Center, we learned that the IRS 
                                                 
29 The IRS’s Filing Season Statistics Report for the week ending March 27, 2021, is rounded to the nearest thousand.

Effects of the COVID-19 Pandemic on Business Tax Return Processing Operations 
destroyed paper-filed information return30 documents.  Management subsequently stated they 
estimated that approximately 30 million documents were destroyed on or around 
March 19, 2021.  These documents are used during post-processing compliance activities, such 
as the IRS’s Automated Underreporter Program.31  IRS management noted that once the tax 
year concludes, the information returns, e.g., Forms 1099, can no longer be processed through 
the Service Center Recognition Imaging Processing System.  This is because the system is taken 
offline for programming updates in preparation for the next filing season.  Also, the Service 
Center Recognition Imaging Processing System is used to scan and process Forms 941, which 
had a higher processing priority than information returns. 
IRS management stated that the decision to destroy these information returns involved 
discussions with both the Wage and Investment and Small Business/Self-Employed Divisions.  
Although IRS management considered maintaining the documents in paper form, they  
decided against this because retrieval of the documents would be difficult.  Further, 
management indicated that the vast majority of information returns are submitted electronically, 
and their priority was to process the backlog of individual and business tax returns.  Small 
Business/Self-Employed Division management subsequently developed a risk assessment  
to evaluate the impact these missing information reporting documents would have on its  
post-processing compliance activities. 
In addition, the IRS has placed the processing of prior and current year Affordable Care Act 32 
information returns on hold since December 23, 2020.  This includes, for example, Forms 1094-C, 
Transmittal of Employer-Provided Health Insurance Offer and Coverage Information Returns; 
Forms 1095-B, Health Coverage; and Forms 1095-C, Employer-Provided Health Insurance Offer 
and Coverage.  The IRS uses these forms in its post-processing compliance activities.  For 
example, the IRS uses information from Forms 1094-C and 1095-C to ensure compliance with 
the Employer Shared Responsibility Provision.33  IRS management indicated that the hold on the 
processing of these information returns is to allow testing of updates to its processing systems.  
The IRS estimated that 5 million prior year Affordable Care Act information returns were on 
hold.  The IRS placed a similar hold on processing these information returns last year from 
December 16, 2019, through July 21, 2020.  The IRS indicated that the closure of its Tax 
Processing Centers in response to COVID-19 prevented the processing of paper forms.  
Moreover, information returns were considered of lower importance compared with other 
priorities.

Updates to computer programming needed to implement legislation passed in 
December 2020 and March 2021 resulted in backlogs of Forms 7200  
The IRS created Form 7200 to enable employers to request an advance payment of the 
employer tax credits, e.g., Sick and Family Leave Credits and Employee Retention Credit.  As of 
December 30, 2020, the IRS reported having 3,079 Forms 7200 and other non-Form 7200 
submissions in review.  However, by April 6, 2021, this increased to 12,222 Forms 7200 and other 
non-Form 7200 submissions in review.34  The IRS published the Tax Year 2021 Form 7200 on 
February 4 2021, and started reviewing Forms 7200 on March 25, 2021.  The IRS began 
processing Tax Year 2021 Forms 7200 on April 13, 2021, two months after the release of the 
form. 
When we discussed our concern with IRS management, they explained that Forms 7200 could 
not be processed during this period because the IRS had to update processes and procedures  
to incorporate legislative changes.  The Consolidated Appropriations Act, 2021, signed on 
December 27, 2020, extended the Sick and Family Leave Credits to March 31, 2021, and the 
Employee Retention Credit to June 30, 2021.  Additionally, this legislation updated the credit 
amount and requirements on the Employee Retention Credit.  In some instances, an employer 
who received a Paycheck Protection Loan can also receive the Employee Retention Credit, 
whereas, previously they were not eligible.  Further, the American Rescue Plan Act of 2021 
signed on March 11, 2021, further extended the Sick and Family Leave Credits to 
September 30, 2021, and the Employee Retention Credit to December 31, 2021. 
These legislative changes required the Information Technology organization to update internal 
systems to allow for the processing and posting of these first quarter forms, but also 
necessitated updating the automated tool that the Form 7200 reviewers use to research 
accounts, identify if forms are/are not processable, and input the adjustments for the credits.  
When asked if IRS management notified taxpayers of this processing delay, management stated 
they did not. 
Finally, IRS management noted that there was an increase of Tax Year 2020 Forms 7200 sent 
after December 2020.  This occurred because of the retroactive change to the Employee 
Retention Credit.  In instances in which an employer filed a Form 7200 for a prior quarter to 
request the Employee Retention Credit, their form was being rejected because the forms were 
filed after the deadline to file for the quarter.  According to the IRS, these taxpayers would have 
received a rejection letter explaining this along with instructions on how to resolve.  In 
January 2021, the IRS published an article on IRS.gov advising taxpayers that they could claim 
the retroactive Employee Retention Credit on their fourth quarter 2020 Form 941 (if they had 
not already submitted that for processing), or they could file a Form 941-X, Adjusted Employer’s 
QUARTERLY Federal Tax Return or Claim for Refund.  In an effort to work through the backlog of 
Forms 7200, the Small Business/Self-Employed Division increased the number of reviewers and 
requested overtime. 
                                                 
34 This figure includes timely filed Tax Year 2021 and untimely filed Tax Year 2020 Form 7200 submissions.  This could 
also include e-fax submissions that contained multiple Forms 7200, blank pages, and other non-Form 7200 
submissions.

Balance due notices were issued because of the mail backlog 
Our analysis identified that some penalties were erroneously assessed.  For example: 
• 
The IRS has assessed 2,545,120 Failure to Pay penalties from April 1, 2020, through 
December 31, 2020, totaling almost $1.4 billion.  During this same time, the IRS has fully 
abated 24,926 of these Failure to Pay penalties totaling more than $738 million because 
the taxpayer in fact made a tax payment, but the payment was not processed timely.  In 
addition, our review found that 3,378 of these penalties totaling more than $54 million 
were refunded to the taxpayer because the taxpayer paid the penalty assessed. 
• 
The IRS has assessed 577,835 Failure to File penalties from April 1, 2020, through 
December 31, 2020, totaling almost $1.2 billion.  During this same time, the IRS has fully 
abated 217,924 of these Failure to File penalties totaling about $475 million because the 
taxpayer filed a timely extension.  In addition, our review found that 1,103 of these 
penalties totaling more than $13 million were refunded to the taxpayer because the 
taxpayer paid the penalty assessed. 
Taxpayers receive notices for a balance due, late payments, and/or late returns.  Although the 
Department of the Treasury extended the due date of payments and return filings, penalties 
were assessed when the extended dates or required payments were not met.  IRS management 
indicated that notices are legally required when there is an unpaid balance due.  However,  
the backlog of mail caused erroneous penalties and notices due to unprocessed tax forms,  
e.g., extensions of time to file a tax return or taxpayer payments.  To mitigate burden to 
taxpayers, on May 9, 2020, the IRS implemented programming to pause balance due accounts 
from progressing to their next status if they remain unresolved.  The pause expired in late 
October 2020. 
Finally, the IRS erroneously assessed 211 Failure to Pay penalties totaling $45,451.  When we 
advised the IRS of this issue on February 2, 2021, the IRS indicated that this occurred due to a 
programming error that did not recognize the grace period for the Failure to Pay penalty.  The 
IRS indicated that it implemented a programming change on February 25, 2021, that will correct 
the error and adjust the accounts with the erroneous penalties we identified.  However, our 
review of a judgmental sample35 of 25 of the 211 taxpayer accounts identified that not all 
penalties had been abated as of April 6, 2021.  We followed up with management and they 
indicated that the Office of Servicewide Penalties anticipates the adjustments will be input the 
week of April 12, 2021.  As of April 22, 2021, we confirmed that our sample of 25 taxpayer 
accounts had an abatement of the Failure to Pay penalty. 
Some business taxpayers were assessed incorrect penalty amounts during the  
relief period  
Our review identified that the IRS incorrectly assessed 1,256 estimated tax (ES) payment 
penalties totaling $876,121 from April 1, 2020, through December 31, 2020.  Taxpayers can incur 
a penalty when one or more of the four estimated tax payments is paid late or underpaid,  
                                                 
35 A judgmental sample is a nonprobability sample, the results of which cannot be used to project to the population. 

 
Page  12

i.e., not enough.  The IRS may assess the penalty when the taxpayer does not self-assess the 
penalty or incorrectly calculates the penalty using Form 2220, Underpayment of Estimated Tax 
by Corporations. 
The penalty is calculated based on, among other factors, the due date of the return and the 
number of days the ES payment is late.  As discussed previously, the Department of the Treasury 
granted tax relief that postponed various tax payment deadlines that occurred starting on 
April 1, 2020.  This allowed businesses until July 15, 2020, to pay any taxes that were originally 
due during this period including ES payments.  While the IRS submitted an information 
technology work request to update penalty processing on July 15, 2020, to recognize the 
postponement of ES payment dates, the programming was not implemented until January 2021.  
The relief provided reduced the amount of the ES penalty, but did not eliminate it. 
As a result, ES penalties assessed for business taxpayers, with tax years ending between 
April 2020 and December 2020 and that were filed before January 2021, had their penalties 
calculated without considering the relief, and generally were higher in amount than required.  
When we brought our concern to IRS management’s attention on September 3, 2020, the  
IRS indicated that there were not enough fiscal year filers to justify implementing the 
programming earlier.  In addition, they planned to perform a review after the end of Processing 
Year 2020 to identify ES penalties assessed in error.  On March 23, 2021, the IRS stated that  
they performed a review using data extracts to identify impacted taxpayers.  Their analysis 
identified 1,295 business accounts with penalties totaling $934,148 that will be subject to the 
manual review process.36  The IRS anticipates making these corrections later in Fiscal Year 2021. 
Recommendation 1:  The Commissioner, Wage and Investment Division, should coordinate 
with the Office of Servicewide Penalties to ensure that the 1,295 taxpayer accounts with 
potential incorrect ES penalties are reviewed and corrected as necessary.  
 
Management’s Response:  The IRS agreed with this recommendation.  The Office of 
Servicewide Penalties completed the review and correction of the 1,295 taxpayer 
accounts.  The corrections were posted to accounts the week of April 15, 2021, and 
notices were generated to the taxpayers with a notice date of May 10, 2021. 
Case Inventories Continue to Grow as Backlogged and Current Year Business 
Returns Are Processed 
Both paper-filed and electronically filed tax returns identified with error(s) are sent to the IRS’s 
Error Resolution function for tax examiner review.  When a tax return is identified with certain 
types of error conditions, the IRS suspends the tax return from processing and sends the tax 
return to a tax examiner to address the error.  The IRS’s Error Resolution function is responsible 
for correcting these error conditions.  Once corrected, the tax return will continue to be 
processed.  Similarly, processing of the tax return and other forms can also be delayed due to 
                                                 
36 The IRS’s analysis was as of February 25, 2021, while our analysis was through December 31, 2020.  As a result, the 
IRS identified additional penalties assessed.

other issues on the return or tax account.  Other functions working these issues in the Tax 
Processing Centers include: 
• 
Rejects – This work includes returns which cannot be processed, usually due to missing 
or incomplete information and in which a tax examiner needs to receive additional 
information from the taxpayer in order to continue processing the return. 
• 
Unpostables – This work includes returns with a transaction that will not post to the 
taxpayer’s account because it failed validity checks. 
• 
Entity – This work includes payments, returns, and forms that require research for 
Employer Identification Numbers37 or perfection of the business taxpayer’s account.   
In addition to the Tax Processing Centers, the IRS works additional business account issues in its 
Accounts Management function.38  This work includes amended business tax returns, 
correspondence, and the issuance of Employer Identification Numbers.  Figure 7 shows the case 
inventories for each of these functions continue to grow.

Systemic Payment Processing Limitations Caused Delays in Processing 
Remittances  
Following the reopening of the Tax Processing Centers in June 2020, IRS systems did not allow 
for the automated processing of remittances it had received during the shutdown.  The system 
used to scan and process remittances could not process remittances that were more than 
30 days after the received date (essentially all remittances that were part of the backlogged 
                                                 
37 A unique, nine-digit number used to identify a taxpayer’s business account. 
38 The Accounts Management function is responsible for assisting taxpayers with questions about the tax laws, their 
account, and the status of their refunds and adjusting their tax accounts when necessary. 
39 This does not include cases that the Accounts Management classifies as both, i.e., either an individual and  
business case.  This work includes refund inquiries and updates to the Centralized Authorization File.  This inventory 
included 867,625 cases as of May 30, 2020; 1,475,942 cases as of December 26, 2020; and 1,795,103 cases as of 
March 27, 2021.   

 
Page  14 
Effects of the COVID-19 Pandemic on Business Tax Return Processing Operations 
mail).  As a result, management requested assistance from tax examiners in the Accounts 
Management function to manually process these remittances requiring additional time to 
process and causing further delays.  The IRS could not provide an estimate of the number of 
payments that needed to be processed manually due to this limitation; however, we noted that 
almost 1.3 million payments totaling more than $14 billion were processed manually during 
June 2020 to October 2020 to prepare the payment for deposit. 
In our discussions with IRS management, they stated that they were aware that the remittance 
processing system 30-day limitation has always been in place, but were unaware that the 
programming could be changed.  However, as part of the process of installing a new payment 
processing system, they found that the number of days for the limitation could be changed.  As 
a result, IRS management stated that they had the current payment processing system 
programming updated on October 1, 2020, to allow remittances dated up to 180 days from 
receipt to be processed systemically. 
Redirecting more payments to the lockboxes could facilitate reducing the backlog 
While the majority of paper payments made to the IRS are directed to a lockbox site, some 
payments continue to be required to be sent directly to a Tax Processing Center.  For example, 
payments with a Form 1041 and Form 1065 are required to be sent to a Tax Processing Center.  
During Fiscal Year 2020, IRS reports show that more than 6.9 million payments totaling  
more than $37.6 billion were processed at the IRS’s Tax Processing Centers.  More than 
339,000 payments totaling $3.4 billion were received by the IRS’s own field office employees, 
i.e., employees who work in Examination, Collection, Appeals, etc.  IRS guidelines require that 
the field offices send the payments to the Tax Processing Centers. 
The lockbox network did not shutdown during the pandemic, whereas the Tax Processing 
Centers closed with no payments being processed.  As such, lockbox sites continued to process 
payments received during this closure.  On September 30, 2020, we asked management whether 
there were plans to continue to move payments to lockbox sites.  Management stated that 
additional programming is required to allow processing of additional form types by the lockbox 
sites.  Management noted that they would evaluate lockbox locations accepting additional 
payments at the conclusion of the 2021 Filing Season.  As part of its evaluation, the IRS should 
consider remittances received by field office operations being sent for processing to the lockbox 
sites.  As more payments are directed to the lockbox sites, IRS employees are available to 
process more complex payments, reducing payment processing backlogs should a similar 
situation arise again. 
Recommendation 2:  The Commissioner, Wage and Investment Division, should evaluate the 
feasibility to direct additional types of payments from Tax Processing Centers to lockbox sites.  
This evaluation should also assess the feasibility of directing payments received by field office 
employees to lockbox sites for processing.  
 
Management’s Response:  The IRS agreed with this recommendation.  IRS management 
stated that the lockbox network has updated the Lockbox Electronic Network Imaging 
Functional Specification Package to include processing capability for 23 additional 

 
Page  15 
Effects of the COVID-19 Pandemic on Business Tax Return Processing Operations 
Computer Paragraph notices.  These additional Computer Paragraph notices are not 
currently directed to a lockbox site; however, should a site receive a notice, they will have 
the capability to process the remittance rather than being required to forward it to a 
Submission Processing Center.  Management is analyzing the volumes associated with 
these notices and current lockbox site volumes to determine which notices, if not all, can 
be revised to have the remittance sent directly to a lockbox facility.  Additionally, IRS 
management has evaluated the feasibility of directing payments received by field office 
employees to the lockbox sites and determined it was not feasible because lockbox sites 
do not have access to the IRS’s internal systems and processes needed for research and 
accountability.

Appendix I 
Detailed Objective, Scope, and Methodology 
Our overall objective was to assess the IRS’s actions to address the backlog of unworked 
inventory affecting business taxpayers due to Tax Processing Center closures resulting from the 
COVID-19 pandemic.  To accomplish our objective, we: 
• 
Evaluated the IRS’s plans to address backlogs of business paper return filings once the 
Tax Processing Centers reopened. 
• 
Monitored the IRS’s plan to increase hiring for Filing Season 2021 to determine how 
many employees are available to process the backlog of business tax returns as well as 
the current business tax returns. 
• 
Identified sources, i.e., inventory reports used, for tracking backlogs of business tax 
returns. 
• 
Tracked and monitored the backlogs of business paper tax return filings. 
• 
Identified the IRS’s plan to create and use priority documents to assist employees in 
processing of backlog business tax returns. 
• 
Analyzed specific penalties to business return filers, resulting from the backlog of 
inventory, to determine if the IRS was correctly assessing penalties and abating them 
when necessary. 
• 
Analyzed specific penalties related to business return filers, resulting from the relief 
period granted to filers, in which the IRS had incorrectly assessed penalties. 
• 
Determined if the IRS is timely depositing remittances for current and prior year business 
tax returns that were not timely processed due to the pandemic. 
• 
Obtained information from the Business Master File and identified 211 taxpayer accounts 
that were erroneously assessed Failure to Pay penalties during Filing Season 2020.  We 
selected a judgmental sample of 25 taxpayer accounts to determine if the IRS abated the 
erroneous penalty.  We used a judgmental sample because we did not plan to project 
the population. 
Performance of This Review 
This review was performed with information obtained from the Wage and Investment  
Division Headquarters in Atlanta, Georgia, and the Wage and Investment Division Submission 
Processing function offices in Kansas City, Missouri, and Ogden, Utah, during the period 
May 2020 through April 2021.  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 Russell P. Martin, Assistant Inspector General for Audit 
(Returns Processing and Account Services); Diana M. Tengesdal, Director; Darryl J. Roth, Audit 
Manager; Nikole L. Smith, Lead Auditor; Christopher W. Harding, Auditor; Lorenzo D. Moss, 
Auditor; and Cally M. Sessions, Auditor. 
Validity and Reliability of Data From Computer-Based Systems  
During this review, we obtained extracts from the Business Master File, which were available on 
TIGTA’s Data Center Warehouse.  We selected judgmental samples of each extract and verified 
that the data in the extracts were the same as the data captured in 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.  Based on the results of our tests, we 
believe that the data used in our review were reliable. 
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:  the process for planning, 
organizing, directing, and controlling program operations for the 2020 Filing Season.  We 
evaluated these controls by meeting with IRS management, reviewing IRS procedures, and 
reviewing IRS reports.

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: 
• 
Taxpayer Rights and Entitlements – Actual; 211 taxpayer accounts erroneously assessed 
Failure to Pay penalties totaling $45,451 (see page 6). 
Methodology Used to Measure the Reported Benefit: 
Our analysis of the Business Master File identified 211 taxpayer accounts erroneously assessed 
the Failure to Pay penalty totaling $45,451.  This occurred due to a programming error that did 
not recognize the grace period for the payment due date.  The IRS implemented a correction on 
February 25, 2021, to correct the programming error and adjust the accounts with the erroneous 
penalties we identified. 
Type and Value of Outcome Measure: 
• 
Taxpayer Rights and Entitlements – Actual; 1,256 taxpayer accounts incorrectly assessed 
$876,121 in ES penalties (see Recommendation 1). 
Methodology Used to Measure the Reported Benefit: 
Our analysis of the Business Master File identified 1,256 taxpayer accounts erroneously assessed 
$876,121 in ES penalties.  This occurred due to a programming error that did not recognize the 
relief for tax payments due between April 1, 2020, and July 15, 2020.  We identified that business 
taxpayers with tax years ending between April 2020 and December 2020 and filed before 
January 2021 had ES penalties calculated without considering the relief.
