Why 401 k Compliance Should Matter to You

As an employer offering a 401 k plan, you’re providing a valuable benefit to your team—but with this benefit comes responsibility. Staying compliant with IRS and Department of Labor regulations isn’t just about avoiding penalties; it’s about protecting your employees’ financial futures and maintaining your business’s reputation.
When you maintain proper compliance, you:

• Preserve the tax-qualified status of your plan
• Safeguard your employees’ retirement savings
• Reduce your personal liability as a fiduciary
• Avoid costly penalties from regulatory agencies

Understanding the 2025 Contribution Limits

The IRS updates contribution limits annually to ensure fairness. For 2025, projections indicate:

• Employee elective deferrals: $23,000
• Additional catch-up contributions (for those 50+): $7,500
• Combined employer/employee contribution limit: $69,000
• Highly Compensated Employee threshold: $155,000

Proactively monitoring these limits throughout the year helps prevent excess contributions that could trigger penalties.

Timely Deposits: A Critical Compliance Area

One of the most common compliance issues we see involves deposit timing. The Department of Labor requires employee contributions to be deposited “as soon as administratively feasible”—typically within 7 business days for smaller businesses and 3-5 days for larger ones.

Missing these deadlines can result in:

• Penalties and excise taxes
• Potential plan disqualification
• Possible employee lawsuits

Consider automating your payroll deductions to ensure timely and accurate deposits.

Non-Discrimination Testing: Ensuring Fairness

Your 401(k) plan must demonstrate it doesn’t unfairly benefit highly compensated employees through regular testing:

• The ADP Test examines employee salary deferrals
• The ACP Test analyzes employer-matching contributions
• The Top-Heavy Test ensures key employees don’t control more than 60% of plan assets

If your plan fails these tests, you’ll need to take corrective action such as refunding excess contributions or making additional contributions to non-highly compensated employees.

Simplifying Compliance with Safe Harbor Plans

Many employers find that Safe Harbor 401(k) plans offer a streamlined approach to compliance by automatically satisfying non-discrimination testing requirements. Options include:

• Basic Match: 100% match on the first 3% of compensation, plus 50% match on the next 2%
• Enhanced Match: 100% match on up to 4% of compensation
• Nonelective Contribution: At least 3% contribution to all eligible employees

Beyond simplifying compliance, these plans often boost employee participation rates.

Correcting Compliance Issues

If you discover compliance problems, prompt correction can minimize penalties. Common remedies include:

• Refunding excess contributions
• Making additional contributions where needed
• Submitting a Voluntary Correction Program application to the IRS

Annual plan audits can help identify potential issues before they become serious problems.

Best Practices for Maintaining Compliance

Consider implementing these strategies to stay ahead of compliance requirements:

• Automate payroll deductions for consistent, timely deposits
• Schedule annual compliance reviews with fiduciary experts
• Partner with a third-party administrator to manage compliance details
• Educate your team about contribution rules and benefits
• Explore Safe Harbor options for simplified compliance
