How to Correct a Top-Heavy 401(k) Plan: A Comprehensive Guide
Are you a business owner or plan administrator wondering if your 401(k) plan is "top-heavy"? Do you find yourself scratching your head at the thought of IRS compliance and complex retirement plan rules? You're not alone! Many small to medium-sized businesses face this challenge, and understanding how to navigate it is crucial for maintaining your plan's qualified status and avoiding hefty penalties.
A top-heavy 401(k) plan essentially means that the majority of your plan's assets are concentrated in the accounts of "key employees." The IRS has strict non-discrimination rules to ensure that retirement plans benefit all employees, not just the highly compensated or owners. If your plan is determined to be top-heavy, you'll need to take corrective action. But don't worry, we're here to guide you through it step-by-step.

| How To Correct A Top Heavy 401k Plan |
Step 1: Understanding What "Top-Heavy" Actually Means
Before we dive into corrections, let's ensure we're on the same page about what makes a 401(k) plan top-heavy. This is where many businesses get caught off guard!
What is a Key Employee?
The IRS defines a "key employee" as someone who, at any time during the prior plan year, met one of the following criteria:
An officer with annual compensation exceeding a certain indexed amount (e.g., $220,000 for 2024).
A more than 5% owner of the business.
A more than 1% owner of the business and has annual compensation exceeding $150,000 (not indexed).
It's important to note that family attribution rules may apply, meaning that if a spouse, parent, child, or grandparent of an owner has a certain percentage of ownership, they may also be considered a key employee.
How is Top-Heavy Status Determined?
Your plan is considered top-heavy if, as of the last day of the preceding plan year (the "determination date"), the aggregate value of the plan accounts of all key employees exceeds 60% of the aggregate value of all employee accounts under the plan.
For example, if on December 31, 2024 (the determination date for the 2025 plan year), the total value of key employee accounts is $650,000 and the total value of all plan accounts is $1,000,000, then your plan is top-heavy (65% > 60%).
This test is performed annually, so a plan that wasn't top-heavy last year could become top-heavy this year. Factors like employee turnover, significant contributions by key employees, or low participation from non-key employees can all contribute to a plan becoming top-heavy.
Step 2: Identifying If Your Plan is Top-Heavy
This is not a theoretical exercise; it's a critical compliance check! Your Third-Party Administrator (TPA) or plan provider typically performs this test for you. However, it's your responsibility as the plan sponsor to understand the results and take action if needed.
Reviewing Your Annual Compliance Report
Tip: Read once for gist, twice for details.
Each year, you should receive a detailed compliance report from your TPA. This report will explicitly state whether your plan passed or failed the top-heavy test.
Look for clear indicators: The report will usually break down the key employee and non-key employee account balances and show the calculated top-heavy ratio.
Understand the "determination date": Remember the test is based on the prior year's-end balances. So, a top-heavy determination for December 31, 2024, means your plan is top-heavy for the entire 2025 plan year, and any required corrections apply to that year.
If you're unsure how to interpret your report, don't hesitate to reach out to your TPA for clarification. They are your primary resource for understanding these complex regulations.
Step 3: Understanding the Consequences of a Top-Heavy Plan
Failing the top-heavy test isn't just a slap on the wrist; it comes with specific obligations. The primary consequence is the requirement to make a minimum contribution to your non-key employees.
The Minimum Contribution Rule
If your plan is top-heavy, you generally must contribute a minimum of 3% of compensation to each eligible non-key employee for the plan year.
Lesser of 3% or Highest Key Employee Contribution: The actual minimum required contribution is the lesser of:
3% of the non-key employee's annual compensation, OR
The highest contribution percentage (including elective deferrals) made on behalf of any key employee.
Example: If the highest contribution percentage for a key employee was 2%, then non-key employees only need to receive a 2% contribution, not 3%. However, if a key employee contributed 5%, then non-key employees would still only need to receive 3%.
Vesting Requirements: These minimum top-heavy contributions must be 100% vested within six years, typically through either:
Three-year cliff vesting: 100% vested after 3 years of service.
Six-year graded vesting: A progressive vesting schedule (e.g., 20% after 2 years, 40% after 3 years, up to 100% after 6 years).
Crucially, elective deferrals (employee contributions) made by non-key employees do NOT count towards satisfying this 3% minimum. This means employers must make additional contributions.
What Happens if You Don't Correct It?
Failure to make the required top-heavy minimum contributions can lead to serious compliance issues, including:
Plan Disqualification: The most severe consequence, which can result in significant tax penalties for both the employer and employees.
IRS Penalties: Fines and interest for non-compliance.
Loss of Tax Deductions: The employer may lose the ability to deduct contributions made to the plan.
Step 4: Strategies for Correcting a Top-Heavy Plan
Now that you understand the "why," let's explore the "how." There are several ways to address a top-heavy plan, ranging from immediate fixes to long-term plan design adjustments.
Option 4.1: Making the Required Minimum Contribution
This is the most direct and common corrective action. If your plan is determined to be top-heavy, you simply make the required 3% (or lesser) contribution to all eligible non-key employees.
Who is eligible? Generally, any non-key employee who is eligible to defer into the plan and remains employed on the last day of the plan year is eligible. The plan cannot impose a minimum hours requirement for this contribution.
When to make the contribution? While you have until the last day of the plan year following the top-heavy year to deposit the contribution, it's often advisable to do so by the employer's tax filing deadline (including extensions) to claim a deduction for the prior year.
Pros: Straightforward compliance. Cons: Can be an unexpected expense for the employer. Key employees may not receive this additional contribution.
Tip: Pause whenever something stands out.
Option 4.2: Implementing a Safe Harbor 401(k) Plan Design
This is a proactive and popular way to avoid top-heavy testing and often, other non-discrimination tests (like ADP and ACP testing) altogether. A Safe Harbor 401(k) requires the employer to make certain mandatory contributions that automatically satisfy the non-discrimination requirements.
Sub-Option 4.2.1: Safe Harbor Contribution Types
There are generally three main types of Safe Harbor contributions:
Basic Matching Contribution: The employer matches 100% of the first 3% of an employee's compensation deferred, plus 50% of the next 2% deferred (for a maximum match of 4% if an employee defers 5%).
Nonelective Contribution: The employer contributes at least 3% of compensation to all eligible employees, regardless of whether they defer into the plan. This is often the most straightforward for compliance but can be the most expensive.
Enhanced Matching Contribution: The employer matches at a rate at least as generous as the basic matching contribution. For example, 100% match on the first 4% of deferrals.
Important Note: Safe Harbor contributions must be 100% immediately vested.

Pros: Eliminates the need for top-heavy testing and often other complex non-discrimination tests, providing greater certainty and administrative simplicity. Can encourage higher employee participation. Cons: Employer contributions are mandatory, which can be a significant ongoing cost.
Sub-Option 4.2.2: Adopting a Safe Harbor Mid-Year
While typically adopted for a full plan year, under certain circumstances (like newly established plans or plans converting from traditional to safe harbor), a safe harbor provision can be adopted mid-year, often requiring a higher nonelective contribution (e.g., 4% instead of 3%). Consult with your TPA immediately if you are considering this, as strict notice requirements and deadlines apply.
Option 4.3: Adjusting Key Employee Contributions
In some cases, particularly for smaller plans with very few non-key employees, a simple solution can be to limit or eliminate contributions by key employees.
If key employees make no contributions (employee deferrals or employer contributions), then the highest contribution percentage for key employees is 0%, and thus, no minimum top-heavy contribution is required for non-key employees.
Pros: Avoids employer contributions. Cons: Limits the retirement savings opportunities for key employees, which may be counterproductive to the purpose of offering a 401(k) plan.
Option 4.4: Utilizing Profit Sharing Contributions
Profit-sharing contributions can sometimes be used to satisfy the top-heavy minimum contribution requirement. If you make a profit-sharing contribution to all eligible participants that equals or exceeds the required top-heavy minimum (e.g., 3% of compensation for non-key employees), then no additional top-heavy contribution may be needed.
Pros: Offers flexibility, as profit-sharing contributions are often discretionary. Can benefit all employees. Cons: If the profit-sharing contribution is less than the required top-heavy minimum, a separate top-heavy contribution may still be necessary.
Option 4.5: Increasing Non-Key Employee Participation and Deferrals
QuickTip: If you skimmed, go back for detail.
This is a long-term strategy but highly effective. By encouraging more non-key employees to participate in the plan and/or increase their deferral rates, you naturally shift the balance of assets away from key employees, making the plan less likely to become top-heavy.
Sub-Option 4.5.1: Strategies for Boosting Participation
Automatic Enrollment: Implement automatic enrollment, where eligible employees are automatically enrolled in the plan unless they opt out. This significantly boosts participation rates.
Employee Education: Provide clear, concise, and regular education to employees about the benefits of participating in the 401(k) plan, how it works, and how to enroll.
Financial Wellness Programs: Offer financial literacy workshops or access to financial advisors to help employees understand the value of retirement savings.
Employer Matching Contributions: Even if not a Safe Harbor plan, an employer match is a powerful incentive for employees to contribute.
Pros: Improves overall employee financial well-being, helps retain talent, and reduces the likelihood of future top-heavy issues. Cons: Takes time to see results, and may still require a top-heavy correction in the short term.
Step 5: Working with Your Plan Administrator/TPA
Correcting a top-heavy 401(k) plan is not a DIY project. Your plan administrator or Third-Party Administrator (TPA) is your most valuable partner in this process.
Communicate Immediately: As soon as you receive notification of a top-heavy plan (or even if you suspect it might be), contact your TPA.
Discuss Options: Your TPA can help you analyze the best correction strategy for your specific business, considering your budget, goals, and employee demographics.
Ensure Proper Documentation: Any corrective actions or plan amendments must be properly documented and communicated to employees as required by IRS regulations.
Stay Informed: Regularly review your plan's performance and compliance reports. Proactive monitoring can help you identify potential issues before they become significant problems.
Conclusion: Staying Compliant and Proactive
A top-heavy 401(k) plan is a common occurrence, especially for smaller businesses. While it triggers specific compliance requirements, it's a manageable issue with the right approach. By understanding the rules, diligently monitoring your plan, and working closely with your plan administrator, you can ensure your 401(k) remains compliant, provides valuable benefits to all your employees, and avoids potential penalties.
Remember, proactively addressing potential issues is always better than reacting to failures. Regularly review your plan design, consider a Safe Harbor approach if appropriate, and educate your employees on the benefits of participation. This will set your 401(k) plan up for long-term success and compliance.
10 Related FAQ Questions
How to calculate if my 401(k) plan is top-heavy?
To calculate if your plan is top-heavy, sum the account balances of all "key employees" (officers with compensation over the limit, >5% owners, or >1% owners with compensation over $150,000) as of the last day of the prior plan year. Then, divide this sum by the total account balances of all employees (key and non-key). If the result is greater than 60%, your plan is top-heavy.
How to define a "key employee" for 401(k) top-heavy testing?
A key employee is defined as an employee who, at any time during the prior plan year, was an officer earning over the IRS-indexed amount (e.g., $220,000 for 2024), a more than 5% owner of the company, or a more than 1% owner with compensation exceeding $150,000. Family attribution rules may also apply.
Tip: Rest your eyes, then continue.
How to make the required minimum contribution for a top-heavy 401(k)?
If your plan is top-heavy, you must make an employer contribution to all eligible non-key employees. This contribution is generally the lesser of 3% of their compensation or the highest contribution percentage (including deferrals) made for any key employee. Non-key employee elective deferrals do not count towards this minimum.
How to avoid top-heavy testing altogether?
You can avoid top-heavy testing by implementing a Safe Harbor 401(k) plan. This requires the employer to make mandatory contributions (either a specific matching contribution or a 3% (or 4% for mid-year adoption) nonelective contribution) that are 100% immediately vested.
How to use profit sharing contributions to correct a top-heavy plan?
A profit-sharing contribution can be used to satisfy the top-heavy minimum contribution if it is allocated to all eligible non-key employees and is at least equal to the required top-heavy minimum percentage (e.g., 3% of compensation).
How to encourage non-key employee participation to prevent top-heavy status?
To encourage participation and help prevent top-heavy status, consider strategies like automatic enrollment, offering clear and consistent employee education about the plan's benefits, and providing a generous employer matching contribution.
How to determine the deadline for making top-heavy corrections?
While the top-heavy minimum contribution generally needs to be made by the last day of the plan year following the top-heavy year, it's often advisable to deposit it by the employer's tax filing deadline (including extensions) to claim a tax deduction for the prior year.
How to handle a top-heavy plan if there are no non-key employees?
If your plan consists solely of key employees and no non-key employees, the plan will technically be top-heavy, but no minimum contributions will be required as there are no non-key employees to contribute for.
How to ensure my 401(k) plan remains compliant with top-heavy rules?
To ensure ongoing compliance, regularly review your annual compliance reports from your TPA, understand the definition of key employees, monitor participation rates among non-key employees, and consider a Safe Harbor plan design if consistently facing top-heavy issues.
How to correct a top-heavy failure if the deadline has passed?
If the deadline for making a required top-heavy contribution has passed, it's considered an operational failure. You may be able to correct this under the IRS's Employee Plans Compliance Resolution System (EPCRS) using the Self-Correction Program (SCP) for minor, timely corrected errors, or the Voluntary Correction Program (VCP) for more significant or delayed corrections. Immediate consultation with a qualified professional is essential in this scenario.
