What Is Actual Contribution Percentage (ACP) Test?

The Actual Contribution Percentage (ACP) test is a vital nondiscrimination test applied annually to qualified retirement plans, such as a 401(k) plan, to ensure that the benefits provided do not disproportionately favor Highly Compensated Employees (HCEs) over Non-Highly Compensated Employees (NHCEs). This test falls under the broader umbrella of [retirement plan compliance], specifically addressing the fairness of [employee contributions] and [matching contributions] made to the plan. The primary objective of the ACP test is to prevent situations where HCEs receive significantly greater benefits relative to their compensation compared to NHCEs, thereby upholding the integrity and fairness of the retirement savings system.

History and Origin

The framework for nondiscrimination testing in employer-sponsored retirement plans, including the Actual Contribution Percentage (ACP) test, originates from the Employee Retirement Income Security Act of 1974 (ERISA). This landmark legislation established minimum standards for most voluntarily established private-sector pension and health plans to protect individuals in these plans. Over time, further refinement occurred through subsequent tax laws, notably the Internal Revenue Code (IRC), to ensure that tax-advantaged [retirement plans] truly serve a broad base of employees, not just a select few. The specific regulations governing the ACP test are detailed under Section 401(m) of the [Internal Revenue Code] and its corresponding Treasury Regulations. These regulations specify the calculation and requirements for the ACP test, serving as a critical mechanism to enforce the [nondiscrimination rules] and ensure equitable access to benefits. The U.S. Department of Labor's Employee Benefits Security Administration (EBSA) provides extensive compliance assistance for plan sponsors to navigate these complex regulations.⁵

Key Takeaways

• The Actual Contribution Percentage (ACP) test ensures that employer matching contributions and employee after-tax contributions in a [defined contribution plan] do not favor Highly Compensated Employees.
• It is one of several [nondiscrimination rules] mandated by the IRS to maintain a plan's qualified status.
• Failure to pass the ACP test typically requires corrective actions, such as distributing excess contributions to HCEs or making additional contributions for NHCEs.
• The test compares the average contribution rates of HCEs and NHCEs based on their compensation.
• Plans that include a "safe harbor" provision can be exempt from performing the ACP test, provided they meet specific contribution requirements for all eligible employees.

Formula and Calculation

The Actual Contribution Percentage (ACP) for a group of employees (either HCEs or NHCEs) is calculated as the average of the Actual Contribution Ratios (ACRs) of the eligible employees within that group. An individual employee's ACR is their total employee contributions (after-tax) and [matching contributions] for the [plan year], divided by their compensation for that year. The test itself involves comparing the ACP of the HCE group to the ACP of the NHCE group.

The specific conditions for passing the ACP test are:

1. The ACP for eligible HCEs for the plan year is not more than 1.25 times the ACP for eligible NHCEs for the applicable year; OR
2. The excess of the ACP for eligible HCEs over the ACP for eligible NHCEs is not more than 2 percentage points, AND the ACP for eligible HCEs is not more than two times the ACP for eligible NHCEs for the applicable year.⁴

The formula for an individual's Actual Contribution Ratio (ACR) is:

Where:

• (ACR_i) = Actual Contribution Ratio for employee i
• Employee Contributions (After-Tax) = The employee's after-tax contributions to the plan.
• Matching Contributions = The employer's contributions that match employee contributions.
• Compensation = The employee's compensation as defined by the plan, typically limited by IRS maximums.

The ACP for a group (HCEs or NHCEs) is then:

Interpreting the Actual Contribution Percentage (ACP) Test

Interpreting the Actual Contribution Percentage (ACP) test results is crucial for plan sponsors to ensure their [qualified retirement plan] remains compliant with IRS regulations. A passing ACP test indicates that the plan's design and participant behavior are, on average, not disproportionately benefiting [Highly Compensated Employees]. If the test fails, it means that HCEs are, on average, contributing a higher percentage of their compensation in after-tax or [matching contributions] than is permissible when compared to NHCEs.

Plan administrators must analyze the results to understand why a failure occurred. This could be due to a significant disparity in the participation rates or contribution levels between the two employee groups. For example, if many NHCEs choose not to make [employee contributions] or do not receive significant matching contributions, while HCEs fully utilize these plan features, the test could fail. Corrective actions, such as issuing [corrective distributions] to HCEs or making additional qualified non-elective contributions to NHCEs, are then necessary to rectify the disparity and prevent the plan from losing its tax-advantaged status. The goal is to balance the average contribution rates across the employee spectrum to meet the [nondiscrimination rules].

Hypothetical Example

Consider "TechInnovate Inc.," a company with a 401(k) plan that includes both pre-tax and after-tax [employee contributions], as well as a 50% employer match on the first 6% of an employee's salary.

In a given [plan year], the company has:

• 5 Highly Compensated Employees (HCEs)
• 20 Non-Highly Compensated Employees (NHCEs)

Let's assume the following Actual Contribution Ratios (ACRs) based on their contributions and compensation:

HCEs' ACRs:

• HCE 1: 8%
• HCE 2: 7%
• HCE 3: 6%
• HCE 4: 8%
• HCE 5: 7%

NHCEs' ACRs:

• (Averages for simplification)
• NHCE Group Average: 4%

Calculation:

1. Calculate the ACP for HCEs:
   ACP_HCE = (8% + 7% + 6% + 8% + 7%) / 5 = 36% / 5 = 7.2%

2. ACP for NHCEs (given):
   ACP_NHCE = 4%

3. Apply the ACP test rules:

   • Rule 1: ACP_HCE (7.2%) <= 1.25 * ACP_NHCE (4%)?
     7.2% <= 5% (False)

   • Rule 2:

     • Excess of ACP_HCE over ACP_NHCE <= 2 percentage points?
       7.2% - 4% = 3.2% (Greater than 2 percentage points, so this part of the rule is False)

Since neither condition is met, TechInnovate Inc.'s [401(k) plan] fails the ACP test for this plan year. The company would need to take corrective action, such as returning excess after-tax and matching contributions to the HCEs or making additional qualified non-elective contributions on behalf of the NHCEs to bring the plan into compliance.

Practical Applications

The Actual Contribution Percentage (ACP) test has several practical applications in the realm of [retirement plan compliance] and administration. Primarily, it is a mandatory annual requirement for many employer-sponsored [defined contribution plan]s, particularly those offering [matching contributions] or allowing after-tax employee contributions. Plan sponsors must conduct this test to ensure their plan maintains its [tax-deferred] status and favorable tax treatment.

Beyond regulatory adherence, the ACP test serves as an indicator of plan participation dynamics. A recurring failure of the ACP test can signal that NHCEs are not adequately utilizing the plan's savings features, potentially due to low engagement, lack of financial literacy, or perceived financial constraints. This can prompt employers to review their plan design, communication strategies, or even consider implementing "safe harbor" provisions which, if met, exempt the plan from the ACP test and the similar Actual Deferral Percentage (ADP) test.³ The Employee Benefits Security Administration (EBSA), a part of the U.S. Department of Labor, actively promotes compliance through various programs, including guidance on the Employee Retirement Income Security Act (ERISA), which underpins these tests.² This proactive approach from regulatory bodies underscores the importance of the ACP test in upholding benefit security for American workers.

Limitations and Criticisms

While the Actual Contribution Percentage (ACP) test is essential for ensuring fairness in [qualified retirement plan]s, it does have certain limitations and has faced criticism. One primary critique is its reactive nature: the test only identifies a problem after the [plan year] has ended, requiring potentially complex and burdensome [corrective distributions] or additional contributions to rectify the imbalance. This can lead to administrative challenges and, for HCEs, unexpected taxable income if excess contributions must be refunded.

Another criticism is that the focus on average contribution rates might not fully capture the underlying reasons for disparities. For instance, low participation among [Non-Highly Compensated Employees] could stem from factors unrelated to the plan's design, such as lower disposable income or a preference for other savings vehicles. Some argue that while the test prevents overt discrimination, it doesn't necessarily encourage increased savings among the broader workforce. Research from institutions like the Center for Retirement Research at Boston College has explored the effectiveness of various retirement saving incentives and policies, sometimes noting that tax preferences might not always significantly increase overall retirement saving or participation rates, suggesting a broader policy challenge beyond just nondiscrimination testing.¹ Additionally, some plan designs or complex [profit-sharing plan] structures might struggle to consistently pass the ACP test without careful monitoring and frequent adjustments, placing a significant [fiduciary duty] burden on employers.

Actual Contribution Percentage (ACP) Test vs. Actual Deferral Percentage (ADP) Test

The Actual Contribution Percentage (ACP) test and the Actual Deferral Percentage (ADP) test are both critical [nondiscrimination rules] for [401(k) plan]s, but they evaluate different types of contributions. The primary distinction lies in what each test measures.

The Actual Contribution Percentage (ACP) test focuses on ensuring that [employee contributions] made on an after-tax basis, and employer [matching contributions], do not excessively favor [Highly Compensated Employees] (HCEs) over [Non-Highly Compensated Employees] (NHCEs). It looks at how much an employee contributes after taxes and how much the employer matches, relative to their compensation.

In contrast, the Actual Deferral Percentage (ADP) test specifically examines employee salary deferrals—that is, the pre-tax or Roth [elective deferrals] made by employees to their 401(k) accounts. Its purpose is to ensure that HCEs do not defer a disproportionately higher percentage of their compensation compared to NHCEs.

Here's a simplified comparison:

While distinct, both tests are crucial for maintaining a [qualified retirement plan]'s tax-favored status and upholding the principle of broad-based benefit distribution.

FAQs

Q1: Why is the ACP test necessary for retirement plans?

The ACP test is necessary to comply with [nondiscrimination rules] set by the IRS. Its purpose is to prevent [qualified retirement plan]s from disproportionately benefiting [Highly Compensated Employees] through employer [matching contributions] and employee after-tax contributions, thereby ensuring the plan is fair to all eligible employees.

Q2: What happens if a plan fails the ACP test?

If a plan fails the ACP test, the employer must take corrective actions. Common solutions include distributing "excess aggregate contributions" (the portion of after-tax and [matching contributions] that caused the test failure) back to the [Highly Compensated Employees], or making additional qualified non-elective contributions to [Non-Highly Compensated Employees] to increase their average contribution percentage. Failure to correct the issue can result in the plan losing its qualified status.

Q3: Are all 401(k) plans required to pass the ACP test?

Not all [401(k) plan]s are required to pass the ACP test. Plans that adopt "safe harbor" provisions, which involve meeting specific minimum employer contribution requirements (e.g., a certain matching contribution or a non-elective contribution for all eligible employees), are typically exempt from the annual ACP and ADP [nondiscrimination rules].

Q4: How does compensation affect the ACP test?

Compensation is a key factor because the Actual Contribution Ratio for each employee is calculated as their contributions divided by their compensation. This ensures the test evaluates contributions as a percentage of pay, making the comparison fair across different income levels, whether for [Highly Compensated Employees] or [Non-Highly Compensated Employees].

Q5: Can a company choose not to offer matching contributions to avoid the ACP test?

Yes, if a [defined contribution plan] does not allow for after-tax [employee contributions] and does not offer [matching contributions], then the Actual Contribution Percentage (ACP) test would not apply. However, most employers offer matching contributions to encourage participation and assist employees with retirement savings.
