19.2 IQPA Independent Audit Threshold: SECURE 2.0 100-Participant Account Balance Rule

19.2 IQPA Independent Audit Threshold: SECURE 2.0 100-Participant Account Balance Rule

[!NOTE] The Most Significant Form 5500 Regulatory Reform in Decades Under ERISA §103(a)(3)(A), the plan administrator of an employee benefit plan must engage an Independent Qualified Public Accountant (IQPA) to conduct an annual examination of the plan's financial statements, books, and records. The resulting IQPA audit report and accountant's opinion letter must be attached to Form 5500 Schedule H.

Historically, this audit requirement applied to any plan with 100 or more total eligible participants on the first day of the plan year, including employees who chose not to contribute and had an account balance of zero. For small businesses adopting 401(k) plans, an IQPA audit represents an annual administrative expense often ranging between $10,000 and $25,000. Enacted as part of SECURE 2.0 Act of 2022 §404 and finalized in 2023 DOL/IRS regulatory amendments, the participant counting methodology was completely overhauled to count only participants with account balances. This reform has reshaped small plan compliance and forms a central focus of the ASPPA QKA examination.

The Statutory Audit Mandate: ERISA §103(a)(3)(A)

An employee benefit plan subject to ERISA Title I must maintain accurate financial records and disclose its financial condition annually. When a plan reaches Large Plan status (generally 100 or more participants), ERISA §103(a)(3)(A) mandates an independent certified audit:

• The Independent Auditor: Must be an independent certified public accountant (CPA) or licensed public accountant. The auditor cannot have any direct financial interest in the plan or plan sponsor.
• Audit Opinion Attached to Schedule H: The auditor must render an opinion regarding whether the financial statements and schedules are presented in conformity with U.S. Generally Accepted Accounting Principles (GAAP) or an Other Comprehensive Basis of Accounting (OCBOA).
• Audit Types under AICPA Statement on Auditing Standards (SAS) 136:
  • ERISA Section 103(a)(3)(C) Audit (formerly known as a Limited Scope Audit): An audit procedure where the auditor does not perform auditing procedures on investment assets certified by a "qualified institution" (such as a regulated bank, trust company, or insurance carrier under 29 CFR §2520.103-8). The auditor must test participant data, contributions, distributions, and plan operations.
  • Non-Section 103(a)(3)(C) Audit (formerly Full Scope Audit): An audit where the auditor tests and verifies all investment valuations, transactions, and certifications without statutory certification exemptions.

Participant Counting: Historic Rule vs. SECURE 2.0 / 2023 DOL Rule

The pivotal dividing line between a Small Plan (Schedule I, no audit) and a Large Plan (Schedule H, mandatory audit) is the 100-Participant Threshold measured on the first day of the plan year. Understanding how participants are counted before and after 2023 is vital for the QKA exam.

+---------------------------------------------------------------------------------------------------+

1. The Historic Counting Rule (Pre-2023)

Under the historic regulation, the participant count evaluated on Day 1 of the plan year included every single individual eligible to participate in the plan, regardless of whether they ever contributed a dime or had a penny in an account:

• If an employer with 115 workers offered a 401(k) plan with 1-year eligibility, and 105 employees were eligible, but only 25 chose to participate while 80 deferred nothing and had an account balance of $0, the plan was treated as having 105 participants.
• Consequently, the plan was legally classified as a Large Plan, requiring Form 5500 Schedule H and an annual IQPA audit costing upwards of $15,000 for a plan with only 25 actual savers!
• This statutory anomaly created a massive barrier against adopting automatic enrollment or expanding eligibility to part-time workers.

2. The SECURE 2.0 / 2023 DOL Regulatory Reform

Recognizing this anti-competitive disincentive, the DOL, IRS, and PBGC adopted regulatory changes for plan years beginning on or after January 1, 2023:

$\text{Beginning-of-Year Count} = \sum \text{Participants with an Account Balance on Day 1}$

Under this modernized standard:

• Active Participants with a Balance: Counted.
• Former / Retired / Terminated Employees with a Balance: Counted.
• Deceased Participants whose Beneficiaries Hold a Balance: Counted.
• Eligible Non-Contributing Employees with a $0 Balance: EXCLUDED FROM THE COUNT!

[!IMPORTANT] The Zero-Balance Rule Eliminates Thousands of Unnecessary Audits: Under the new rule, if an employer has 300 eligible employees but only 75 have an account balance as of January 1, the plan has a participant count of 75. The plan is a Small Plan! It files Form 5500-SF (or Form 5500 with Schedule I) and is completely exempt from the IQPA audit mandate.

The "80-120 Participant Rule" (29 CFR §2520.103-1(d))

Congress and the DOL recognized that growing small businesses hovering near the 100-participant mark might oscillate between small plan and large plan status from year to year. Forcing a plan to undergo an audit in Year 1, drop to small plan status in Year 2, and return to large plan status in Year 3 would create severe administrative disruption. To provide stability, 29 CFR §2520.103-1(d) established the 80-120 Participant Rule.

|   If the number of participants with account balances on the first day of the plan year is        |
|   between 80 and 120 (inclusive: 80 <= Count <= 120), the plan administrator MAY ELECT to file     |

+---------------------------------------------------------------------------------------------------+

Operational Rules for Applying the 80-120 Rule:

1. Prerequisite - Ongoing Plan: The 80-120 rule can only be applied to an ongoing plan that filed a Form 5500 return for the immediately preceding plan year. A brand-new plan in its first plan year cannot use the 80-120 rule because there is no prior year filing!
2. Small Plan Category Continuity: If a plan filed as a Small Plan (Schedule I or Form 5500-SF) in Year 1, and on Day 1 of Year 2 its beginning balance count rises to between 100 and 120 participants:
   • The plan is not required to file as a Large Plan.
   • The administrator may elect to file as a Small Plan, avoiding Schedule H and the IQPA audit!
3. Breaching the 120 Ceiling: If the beginning balance count reaches 121 or more participants, the 80-120 rule ceases to provide relief. The plan MUST file as a Large Plan (Schedule H with IQPA audit).
4. Large Plan Category Continuity: Once a plan files as a Large Plan (e.g., after crossing 120 participants), it must continue filing as a Large Plan in subsequent years as long as its beginning count remains at 100 or more. If its count drops into the 80-99 range, the administrator can utilize the 80-120 rule to continue filing as a Large Plan, or elect to drop down to Small Plan status because its count is below 100.
5. Dropping Below 80: If a large plan's beginning count drops to 79 or fewer balance holders, it must file as a Small Plan; the 80-120 rule no longer permits it to file as a large plan.

Qualifying ERISA Fidelity Bond Requirements (ERISA §412)

Every employee benefit plan covered by Title I of ERISA must protect plan assets against fiduciary theft, fraud, and embezzlement. Under ERISA §412, every fiduciary of an employee benefit plan and every person who handles funds or other property of such a plan ("plan officials") must be bonded.

1. Mandatory Bond Amount Calculation

Under ERISA §412(a), the amount of the fidelity bond is fixed by statute:

$\text{Required Fidelity Bond} = \max\left(\$1,000, \; \min\left(\text{Statutory Maximum}, \; 10\% \times \text{Funds Handled}\right)\right)$

• Base Percentage: Exactly 10% of the amount of funds handled during the preceding plan year (or estimated funds handled for a new plan).
• Statutory Floor: A minimum bond amount of $1,000.
• Standard Statutory Ceiling: A maximum bond amount of $500,000 for plans holding standard investments.
• Elevated Statutory Ceiling for Employer Securities: A maximum bond amount of $1,000,000 for plans that hold qualifying employer securities (such as employer stock in an ESOP or a 401(k) plan with a company stock fund).

+---------------------------------------------------------------------------------------------------+

2. What Constitutes "Handling Funds"?

Under 29 CFR §2580.412-6, handling funds encompasses any power or duty that creates a risk of loss through fraud or dishonesty, including: physical contact with cash or checks; authority to sign checks; power to disburse funds; authority to direct investments; or power to transfer funds electronically between accounts.

3. Fidelity Bond vs. Fiduciary Liability Insurance

A frequent ASPPA QKA exam question tests the critical legal distinction between an ERISA fidelity bond and fiduciary liability insurance:

---

Small Plan Audit Waiver Requirements (29 CFR §2520.104-46)

Small plans (< 100 participants with balances) are conditionally exempt from attaching an IQPA audit report to their annual return. Under 29 CFR §2520.104-46, this audit waiver is not automatic; the plan must satisfy two cumulative requirements:

1. The Asset Quality Test (The 95% Rule)

As of the end of the preceding plan year, at least 95% of plan assets must be "qualifying plan assets":

• What are Qualifying Plan Assets? Any asset held by a regulated financial institution (bank, trust company, registered broker-dealer, insurance carrier); shares of mutual funds; participant loans; and investment contracts.
• The Non-Qualifying Asset Remedy: If less than 95% of assets are qualifying plan assets (e.g., the plan holds 20% in raw land, private equity, or physical gold), the plan can still qualify for the audit waiver if any person who handles the non-qualifying assets is covered by an enhanced ERISA fidelity bond equal to 100% of the value of the non-qualifying assets!

2. Summary Annual Report (SAR) Mandatory Disclosure

The plan administrator must include a specific statutory notice in the annual Summary Annual Report (SAR) distributed to participants, disclosing:

• The name of each financial institution holding qualifying plan assets;
• The name of the surety company issuing the fidelity bond;
• A statement notifying participants that they have a legal right to inspect financial statements and custodial records; and
• A statement that participants may contact the DOL Employee Benefits Security Administration (EBSA) if they cannot obtain copies of custodial statements.

[!WARNING] Failing the Audit Waiver Triggers Schedule H and an Audit: If a small plan holds 15% non-qualifying assets and fails to obtain the 100% enhanced fidelity bond for those assets, or fails to include the mandatory audit waiver disclosures in its SAR, the small plan instantly loses its audit waiver. It is forced to hire an IQPA and attach an audited financial report to Form 5500!

Comprehensive Worked Scenario: Counting & Bonding

Precision Optics Laboratory, Inc. sponsors the Precision Optics 401(k) Plan. The plan year is the calendar year. The TPA is determining reporting status and bonding for the 2024 plan year.

Plan Demographics as of January 1, 2024:

• Active Employees Eligible to Defer: 160 employees.
  • 70 active employees make elective deferrals and hold account balances;
  • 25 active employees made deferrals in prior years, stopped deferring, but hold balances;
  • 65 active employees are eligible to defer but never enrolled and have a $0 balance.
• Terminated Participants: 15 terminated employees maintain vested account balances.
• Deceased Participants: 2 deceased employees whose surviving spouses hold balances.
• Prior Year Filing (2023): Filed as a Small Plan with Schedule I.
• Plan Financial Assets Handled (as of 12/31/2023): Total assets = $4,800,000 (all invested in qualifying mutual funds, zero employer stock).

Step 1: Compute Participant Count under SECURE 2.0 / 2023 Rules:

$\text{Active Contributing (with balance)} = 70$ $\text{Active Non-Contributing (with balance)} = 25$ $\text{Terminated (with balance)} = 15$ $\text{Beneficiaries (with balance)} = 2$ $\text{Eligible Non-Deferrers (ZERO balance)} = 0 \quad \text{(EXCLUDED!)}$ $\text{Total Beginning-of-Year Participants with Balances} = 70 + 25 + 15 + 2 = \mathbf{112 \text{ Participants}}$

Step 2: Apply the 80-120 Participant Rule:

• The participant count is 112.
• Because 112 is between 80 and 120, Precision Optics is eligible to apply the 80-120 Participant Rule of 29 CFR §2520.103-1(d).
• Because the plan filed as a Small Plan in 2023, the plan administrator elects to continue filing as a Small Plan for 2024!
• Impact: Precision Optics avoids Schedule H and avoids the $15,000 IQPA independent audit expense!

Step 3: Calculate Required ERISA §412 Fidelity Bond:

• Total funds handled: $4,800,000.
• Base bond percentage: $10% \times $4,800,000 = $480,000$.
• Compare against statutory limits:
  • Minimum: $1,000.
  • Maximum: $500,000 (no employer stock held).
• Required Fidelity Bond: Exactly $480,000.

Common ASPPA QKA Exam Traps

• Exam Trap 1: Counting Zero-Balance Eligible Employees Post-2023: Exam questions will explicitly list 130 eligible employees where 50 have never contributed and hold $0 balances, and ask whether an audit is required. Candidates using pre-2023 rules count all 130 and mandate an audit. Under the post-2023 SECURE 2.0 rule, only the 80 balance-holders are counted; the plan is small (< 100) and no audit is required!
• Exam Trap 2: Attempting to Use the 80-120 Rule in the First Plan Year: A brand-new plan establishes on January 1, 2024 with 105 participants holding account balances from a spin-off. Candidates attempt to file as a small plan under the 80-120 rule. The 80-120 rule requires a prior year filing; it can NEVER be used in a plan's first year! With 105 participants, a new plan MUST file as large.
• Exam Trap 3: Confusing Fidelity Bond Maximums for Employer Stock: A plan with $12,000,000 in assets holds $2,000,000 in employer stock. Candidates cap the bond at $500,000. Under ERISA §412, plans holding employer securities have an elevated statutory cap of $1,000,000. The required bond is 10% of $12M capped at $1,000,000!
• Exam Trap 4: Fiduciary Liability Insurance Substituting for Fidelity Bond: A plan sponsor purchases a $2,000,000 fiduciary liability policy with a $25,000 deductible and cancels its ERISA fidelity bond, believing the fiduciary policy provides superior coverage. This is an ERISA violation! Fiduciary liability insurance is optional and cannot satisfy the mandatory ERISA §412 bonding requirement.
• Exam Trap 5: Failing the 95% Audit Waiver Rule: A small plan holds $800,000 in mutual funds and $200,000 in raw land (20% non-qualifying). Candidates assume the small plan is exempt from the audit simply because it has 40 participants. Because non-qualifying assets exceed 5%, the plan must obtain a 100% bond ($200,000) on the non-qualifying assets or it MUST undergo an IQPA audit!
