Administering a 40 k plan comes with immense responsibility, and failing to stay in compliance with federal regulations can lead to severe consequences.

With decades of experience guiding employers through the complex world of retirement plan compliance, our team provides more than oversight—we offer strategic partnership. In this comprehensive guide, we break down the most frequent compliance issues, explain their root causes, and deliver proactive solutions that create a foundation of long-term fiduciary success.
The Importance of 401 k Compliance for Iowa Employers
Maintaining a compliant 401(k) plan is more than a legal requirement—it’s a crucial part of fulfilling your fiduciary duty and protecting employee trust. For Iowa businesses, compliance can also be the difference between a sustainable benefits package and costly IRS or Department of Labor (DOL) investigations.
Non-compliance can lead to:
- Disqualification of the retirement plan
- Substantial fines and penalties
- Legal action from participants
- Reputational damage
- Personal liability for plan fiduciaries
Ensuring that your plan is properly designed, administered, and monitored is not just good business practice—it’s a necessary step in fostering workforce confidence and reducing corporate risk.
Top 10 401 k Violations—and Their Professional Solutions
1. Late Deposit of Employee Contributions
Federal rules dictate that salary deferrals must be deposited into the plan as soon as reasonably possible. For many plans, this is within three to five business days.
Professional Correction:
Calculate and restore lost earnings using DOL methodologies. Implement automated payroll interfaces and internal controls to ensure timely deposits. Document process improvements and maintain audit-ready records.
2. Incorrect Eligibility Tracking
Misapplying eligibility rules—such as missing part-time employees or using outdated plan language—can deny participants access to benefits they are legally entitled to.
Professional Correction:
Retroactively enroll affected employees, contribute missed deferrals and match amounts, and calculate applicable earnings. Update eligibility systems, provide fiduciary training, and revise policies accordingly.
3. Plan Document vs. Operations Misalignment
When your actual plan operations deviate from what’s written in your plan document—such as using incorrect match formulas or loan terms—you’ve committed a plan operation failure.
Professional Correction:
Re-align plan operations with documented provisions, or amend the document retroactively with IRS approval. Maintain consistency moving forward through annual compliance reviews.
4. Loan Violations
Improperly issued or administered loans—such as loans exceeding IRS limits, improper repayment schedules, or delinquent repayments—can create taxable events.
Professional Correction:
Recalculate amortization schedules, issue corrective disclosures, and classify deemed distributions properly. Educate employees on loan limits, grace periods, and tax implications.
5. Vesting Schedule Errors
Incorrectly applying vesting can result in overpayments to employees who leave early or underpayments to those entitled to full benefits.
Professional Correction:
Audit past distributions, apply the correct vesting schedule retroactively, and correct all records. Use compliance software with built-in vesting logic to prevent recurrence.
6. Failure of Nondiscrimination Testing
Failing the ADP/ACP or Top-Heavy tests can trigger mandatory refunds to highly compensated employees or required contributions to non-HCEs.
Professional Correction:
Process corrective refunds or employer contributions in a timely manner. Consider adopting Safe Harbor plan provisions to avoid future testing.
7. Missing or Inadequate Participant Notices
Failing to distribute required plan notices—such as Safe Harbor notices, QDIA disclosures, and Summary Plan Descriptions (SPDs)—is a common oversight.
Professional Correction:
Distribute retroactive notices when appropriate, and establish an automated notification system with delivery tracking and annual scheduling.
8. Improper Handling of Distributions
Delaying required minimum distributions (RMDs) or issuing premature payouts without proper documentation can result in tax penalties and participant dissatisfaction.
Professional Correction:
Verify distribution timing protocols, update plan provisions for SECURE 2.0 changes, and maintain logs of distribution approvals and delivery.
9. Unaddressed Historical Violations
Failing to correct known past issues can be viewed as gross fiduciary negligence and attract DOL scrutiny.
Professional Correction:
Document all known violations, prioritize remediation, and file under the IRS Voluntary Correction Program (VCP) when necessary. Maintain internal audit trails.
10. Lack of Formal Fiduciary Processes
Failure to meet fiduciary obligations—such as monitoring investments, benchmarking fees, or maintaining governance records—exposes plan sponsors to legal risk.
Professional Correction:
Establish a fiduciary committee, hold quarterly meetings, and create an Investment Policy Statement. Document all decisions and maintain compliance records in a secure, accessible format.
Root Causes of Noncompliance
The underlying causes of 401(k) plan failures typically stem from:
- Lack of ongoing training for HR or payroll teams
- Disjointed communication between service providers
- Manual processes with little oversight
- Outdated plan documents
- Failure to designate a plan compliance officer
Wittrock Financial conducts a full compliance health check to identify these weaknesses, implement controls, and provide staff training to prevent recurrence.
Correction Programs Available to Plan Sponsors
The IRS and DOL offer structured correction pathways, including:
- Self-Correction Program (SCP): For minor errors corrected within two years
- Voluntary Correction Program (VCP): For significant violations that need IRS approval
- Audit CAP: For corrections made during an audit, often with sanctions
Our specialists handle documentation, calculations, and communications with regulators, ensuring your plan remains in good standing.
Building a Culture of Compliance
Compliance is not a one-time task—it must be built into the culture of your organization.
We help employers:
- Develop compliance calendars
- Assign fiduciary responsibilities
- Conduct training sessions
- Implement real-time monitoring systems
- Perform annual plan governance audits
By integrating these steps, you create a proactive environment that prevents errors and supports long-term plan health.
