Revised employer audit appendix for the tax performance system
Summary ETA issued a revised Appendix E to its Tax Performance System handbook for state employer unemployment tax audits. In January 2024, ETA cancelled this letter and rescinded the revised appendix because it had not solicited public comment. State audit staff were told to return to the prior appendix; this record preserves the withdrawn text for reference.

ADVISORY: UNEMPLOYMENT INSURANCE PROGRAM LETTER NO. 16-23
TO: STATE WORKFORCE AGENCIES
FROM: BRENT PARTON
Principal Deputy Assistant Secretary
SUBJECT: Issuance of Revised Appendix E of the Employment and Training (ET)
Handbook No. 407
1. Purpose. To notify states that Appendix E of ET Handbook No. 407, 4th Edition, Tax
Performance System (TPS), regarding state employer Unemployment Insurance (UI) audit
functions (formerly “field audit functions”) and procedures, has been revised.
2. Action Requested. Administrators are requested to distribute this advisory and the
attachment to appropriate UI tax managers, employer audit staff, and TPS reviewers. There
will be two different effective dates for the revisions to Appendix E: October 1, 2023, or
January 1, 2024 (explanations of each effective date are below).
3. Summary and Background.
a. Summary – This Unemployment Insurance Program Letter (UIPL) announces a revision
to Appendix E of ET Handbook No. 407, 4th Edition, TPS, which concerns state
employer UI tax audits of employers. State employer audit tax staff audit the records of
selected employers to ensure that the employers have complied with state UI laws and
regulations. Appendix E applies to employer audits of contributory employers 1
conducted by state auditors. The revised Appendix E Employer Audits can be found
here: https://www.dol.gov/sites/dolgov/files/ETA/handbooks/2023/Handbook 407/ETA
Appendix-E Employer Tax Audits (Accessible PDF).pdf
Appendix E was last updated in 1999. The U.S. Department of Labor (Department)
Employment and Training Administration (ETA) has revised Appendix E because states
have asked for clarification of prior guidance and changes since 1999 in the audit
program, such as implementation of the Effective Audit Measure (EAM) and the ability
for states to conduct audits remotely. The revised Appendix E replaces Appendix E in
Contributory employers pay contributions into a state unemployment fund based on contribution rates the state had
assigned to each employer.

Appendix E-Field Audit Continuing

(ESM) Part V, Section 3670-3693.2
b. Background – State employer audits are required under the Federal UI Performs
Management System, which the Department developed to meet its responsibilities under
Title 20 C.F.R. Part 602. This regulation requires the Department to assess the timeliness
and accuracy of administration of state UI programs. In accordance with UIPL No. 03-
11, state audit activity is a core measure in the UI Performs Management System. A
comprehensive employer audit program is vital to the administration of a state UI system.
A well-planned and cost-effective employer audit program, executed with other state UI
administrative functions, is an efficient means of ensuring compliance with state UI law
and timely collection of taxes on an equitable basis. Completed audits that meet the
guidelines set forth in Appendix E are reported on the ETA 581 Contribution Operations
report, and they are included in the universe of employer audits that may be subject to
review by TPS acceptance sampling.
4. Guidance.
a. Summary of Major Revisions. A summary of major revisions to Appendix E of ET
Handbook 407, TPS, is below. The revised Appendix E Employer Audits can be
found here: https://www.dol.gov/sites/dolgov/files/ETA/handbooks/2023/Handbook
407/ETA Appendix-E Employer Tax Audits (Accessible PDF).pdf.
i. Changes “Field Audits” to “Employer Audits” to align more closely with current
employer audit practices, which may include both in-person field audits and
remote audits.
ii. Revises the definition of what constitutes a completed employer audit. Prior
guidance listed seven minimum requirements for a completed audit. These seven
requirements remain unchanged. Two requirements have been singled out to
further clarify these already-existing requirements.
A. The revised definition requires that an audited employer paid wages in
covered employment in at least one audited quarter, in accordance with
prior guidance that an auditor verifies the taxable amounts of payments
made by an employer to employees and contributions paid for covered
employment. If an auditor investigated an employer and found that the
employer did not pay wages to employees in covered employment during
the scope of the audit, this activity is not considered an employer audit.
For example, an audit did not occur if the auditor found that the employer
reported all wages to the state as covered employment erroneously.
B. The revised definition of a completed audit includes that an auditor
verified the existence of a business. This addition is consistent with prior
ESM, Part V, Section 3670-3693, addressed state employer UI tax audit functions and procedures and was
included in Appendix E of ET Handbook No. 407, 4th Edition.
guidance that an auditor must include information that the existence of a
business was verified in the audit report.
iii. Includes a detailed description of an auditor's tests to verify the accuracy and
completeness of an employer’s payroll posting system and reported total and
taxable wages. These tests remain unchanged from prior guidance, as described
in Chapter 7 of ET Handbook No. 407. The tests must be completed as a
requirement for an audit to be counted as a completed audit. Since Appendix E is
the primary source of guidance on state audit programs, a description of the tests
has been added to Appendix E for the convenience of Federal and state staff.
iv. Provides a new definition for calendar quarters audited. The term is defined in
revised Appendix E since states report the number of calendar quarters audited on
the ETA 581 report and the term is not clearly defined in current guidance. The
new definition will provide consistency for reporting data on the ETA 581 report.
v. Provides updates for employer selection criteria for audits and includes two policy
changes. These changes provide more flexibility for states to select employers for
audit with the goal to pass all factors of the EAM rather than meet specific
measures. For information on the EAM, see Section 17 in this revised Appendix
and UIPLs No. 30-10 and 03-11.
A. Prior guidance that at least 10% of audit assignments must be randomly
selected from the total universe of contributory employers has been
changed from a requirement to a recommendation.
B. The requirement that at least 1% of total audits required to meet the audit
DLA (now factor 1 of the Effective Audit Measure (EAM)) must be large
employers has been removed.
vi. Revises the definitions for what constitutes the scope of employer audits. Prior
guidance stated that the scope of an audit is the number of quarters examined
without defining “examined.” To clarify what is meant by “examined,” the
revised Appendix established new terms “original quarters” (normally four) and
“extended quarters” because each term deserves separate guidance.
For example, the revised Appendix E reaffirms the difference between auditing
original quarters and extended quarters. Whereas, an auditor is required to verify
the accuracy of the employer’s payroll posting system for the original quarters,
the auditor may omit verifying the accuracy of the employer’s payroll posting
system during the period the audit is extended to cover. However, the auditor
must still verify the employer’s total and taxable wages that were reported to the
state for the extended quarters. In addition, the revised Appendix reaffirms that
the auditor must search for unreported employees in all quarters that the audit was
extended to cover.
vii. Eliminates the current provision that within the context of an audit report, auditors
should collect additional taxes at the time of the audit, and the mention in the
audit report if taxes due were collected or explain why taxes were not collected.
The revised Appendix recommends an auditor’s manager or designated staff to
review each audit report to ensure that the report summarizes adjustments to an
employer’s total wages, taxable wages and/or contributions due that may be
required because of the auditor’s final determination. A manager should check
that adjustments were processed in the state’s automated system.
The state should follow its normal procedures to bill and collect amounts due.
viii. Recommends that states establish timeliness standards for the completion of
audits and audit reports. Since many audits result in adjustments that either bill
employers for additional taxes due or provide credits for overpaid taxes, it is
important to complete audits and prepare audit reports as soon as possible. For
example, a state may establish a policy that an audit should be completed within
90 calendar days from the start of the audit (i.e., when the auditor has a pre -audit
discussion with the employer) and an audit report should be completed within 30
days after the closeout conference. (Note: Each state has the flexibility to
establish its own policy for timely completion of audits and audit reports in
accordance with its UI law and/or regulations.)
ix. Addresses the use of remote audits (or e-audits), which are audits conducted
remotely versus in-person.
x. Adds information on the EAM to the guidance. The prior version of the
Appendix did not include information about the EAM since the EAM was
established after the most recent update to the Appendix. The new information
about the EAM in the revised Appendix is only a summary and a cross reference
to information on the EAM as provided in UIPLs No. 30-10 and 03-11.
xi. Clarifies when states should report audit activity on the ETA 581 Contributions
Operations Report and when to include the audits in TPS acceptance sampling if
the audits involve other states. Prior guidance did not address three specific
situations described below.
A. If, while conducting an audit, an auditor finds workers and wages covered
in another state, the auditor documents the correct payroll for the auditor’s
state. The audit and other adjustments to the wages reported to the
auditor’s state are counted in the state’s ETA 581 Contribution Operations
report and included in the state’s TPS universe of employer audits.
Information regarding wages covered in another state is shared with the
other state based on the auditing state’s procedures on initiating out-of-
state contact.
B. A state that receives data and information from an audit that another state
completed on its behalf, is not counted in the state’s ETA 581
Contribution Operations Report and is not included in the state’s TPS
acceptance sampling universe of employer audits.
C. A joint audit, where auditors from more than one state perform an audit
together, are counted in a state’s ETA 581 Contribution Operations report
and included in a state’s TPS universe of employer audits if employees
and wages are covered in the state.
xii. Reminds states that tax auditors must be merit-staffed governmental employees
and not contractors if the auditors have the responsibility for making
determinations of monetary liability or coverage decisions based on their findings.
The basic UI audit function, as well as certain program audit functions may be
outsourced to the extent they do not involve the exercise of discretion in applying
governmental authority, but rather, involve only the investigation and verification
of past actions taken by governmental or contract employees. The outsourcing of
employer audit activities to contractors is limited to investigations that only gather
data and facts that will be transmitted to a merit-staffed employee who will make
any determination after reviewing the information. See UIPL No.12-01, Change
2 for more information. 3
xiii. Encourages states to participate in the Questionable Employment Tax Program
(QETP) with the IRS. See UIPL No. 17-07 and Training and Employment Notice
No. 03-21 for more information,
b. Effective Dates. ET Handbook No. 407 provides two different timeframes for
conducting employer audit TPS reviews. State TPS reviewers conduct acceptance
sampling of completed employer audits to determine if the audits were completed in
accordance with the Handbook. The effective date of the revision announced in this
UIPL will differ, depending on the timeframe used for TPS audit reviews.
The Handbook allows state TPS reviewers to conduct acceptance sampling of audits
completed in the fourth quarter of the previous calendar year, and the first, second,
and third quarters of the current calendar year. Under this first option, a state
reviewer can begin to review cases in October of the current calendar year. This
option of beginning the review in October instead of January may lessen the
workload burden of reviewing acceptance sampling for other tax functions and the
audit function at the same time in January.
The Handbook provides a second option whereby a state reviewer would conduct
acceptance sampling of audits completed in the four quarters of the calendar year
Unemployment Insurance Program Letter No, 12-01, Change 2, States’ Ability to Exercise Flexibility in Staffing
Models for the Performance of Certain Unemployment Compensation (UC) Administrative Activ ities, Issued
January 8, 2021
under review. Under this option, a state reviewer begins to review sample cases in
January of the next year.
• The revision to Appendix E is effective October 1, 2023, for states choosing to
conduct TPS employer audit reviews that examine audits completed in the fourth
quarter of the previous calendar year, and the first, second, and third quarters of
the calendar year under review (i.e., for calendar year 2024, this would be the
fourth quarter of 2023 and first three quarters of 2024).
• The revision to Appendix E is effective January 1, 2024, for states choosing to
conduct TPS employer audit reviews that examine audits completed in the four
quarters of the calendar year under review (i.e., for calendar year 2024, all four
quarters of 2024).
